Top 25 birds of the week: #Spectacular - Wild Bird Revolution and Top 25 birds of the week: #August - Wild Bird Revolution – A double dose of bird pictures for this week!

A New Look at Ancient Nubia - Archaeology Magazine – South of Egypt….evidence of sophisticated culture centuries before the pharaohs extended their rule to the area.

New fabric could help keep you cool in the summer, even without A/C -- ScienceDaily – Interesting. But are there some negatives to ‘nanofibrous membranes’? Could they be worse pollutants than microplastics if we aren’t careful with them?

Photography in The National Parks: Gearing Up, Staying Safe, And Getting Back Out There with My Cameras at Crater Lake National Park  - I’m still not confident enough to try a road trip to a national park when I am still carefully timing my trips to the grocery store! I’d have to purchase a lot more masks than I have now --- and develop a strategy for ‘rest’ stops along the way.   

Older adults coped with pandemic best, study reveals -- ScienceDaily – This study seems intuitive to me. My husband and I are in the over 65 crowd and post-career. We miss volunteering and traveling…but we are not anxious about a job or childcare or facing financial catastrophe. 2020 is a going to be an odd year for us…but not a bad one. It’s not hard to laugh about not knowing when we’ll get a haircut!

Activities Discovered for Some Inactive Drug Ingredients | The Scientist Magazine® - There is more than the drug in the capsule….and it’s hard to know how many ‘side effects’ to drugs are actually a reaction to something that was supposed to be inert – but isn’t for everyone.

The Weird, Wondrous and Vulnerable American Horseshoe Crab – Cool Green Science – Blue bloods…and ancient…. Can they survive their interaction with humans?

Forty percent of dementia cases could be prevented or delayed by targeting 12 risk factors throughout life -- ScienceDaily – There 9 risk factors identified in 2017 (less education in early life; mid-life hearing loss/hypertension/obesity; later life smoking/depression/social isolation/physical inactivity/diabetes) and now there are 3 being added: excessive alcohol intake, head injury in mid-life, and air pollution in later life.

Forest Photos Captured in Different Seasons Shows the Beauty of Change – Interesting idea of a long-term photography project. I’ll have to start scouting some places easy for me to get to.

Childhood connection to nature has many benefits but is not universally positive, finds review: A connection to nature is complex, as well as positive emotions, it can generate negative emotions linked to issues like climate change -- ScienceDaily – But those negative emotions can lead to actions toward a more livable world….which would net to a positive in the long run.

Unique Activities for Yesterday:

Cicada on the Screen. There don’t seem to be as many cicadas around this year. I hear one occasionally…but no answering song. I hope they are finding mates but would be more confident if there were the usual overlapping songs. There was one on the screen of our covered deck in the early morning. It must have spent the night there and it was not quite warm enough for it to be singing. Later in the day it was gone.

Performance of the Year | The Prairie Ecologist – Video of an Eastern Hognose Snake pretending to be dangerous.

Millennia-Old Rock Art in Israel Offers Window into Lost Culture | Smart News | Smithsonian Magazine – Monuments 4,000 years old…dolmens. There are more than 400 in the same area. A survey of them started 2012 after the first rock art engravings were discovered (14 trident-like shapes on the ceiling of a large dolmen).

Backyard Birding in Central India to Beat Lockdown – Backyard birding - something that is happening around the world during the pandemic!

Granite tors evidence of ice-free Alaska - The Field - AGU Blogosphere – Tors mark the Pleistocene pathway that was free of glaciers for plants and animals during the ice age.

Great, Warm Lakes – This is an article from a month ago…I’m just getting around to reading it. The surface temperatures were warmer than usual as of July…in some of the lakes there are areas warmer by more than 4 degrees C (including most of Lake Michigan)!

Restoration of Sicily’s Temple of Zeus Continues - Archaeology Magazine  - A 26-foot-tall sculpture of Atlas dated to the 5th century BC…and there might have been as many as 40 such statues.

Winners of International Photo Contest Celebrate the Art of Movement – Capturing a moment…freezing motion.

Blood-thinner with no bleeding side-effects is here – Still work to be done….the current formulation is filtered out by the kidneys very quickly. It has applicability in artificial lungs (used to bridge the time between lung failure and lung transplantation) currently.

Poor Everglades Nesting Season A Result of Climate Change and Untimely Storms – It appears that 2020 isn’t a good year for roseate spoonbills and wood storks in Florida.

This Medieval Potion Kills Stubborn Bacteria – “Bald’s eyesalve” – garlic, onion, wine, cow bile. It appears to be effective at combating antibiotic resistant bacterial strains…biofilms that are particularly challenging to kill…including diabetic foot infections.

Unique Activities for Yesterday:

3 racoons. Our birdfeeder camera made a video of some visitors to our deck just before 2 AM on Wednesday, 8/5: three racoons! They looked smaller than the female that came several times earlier in the summer. Perhaps they were her young….out foraging on their own (maybe she was nearby). They were no more successful than she was getting seed from our squirrel proof birdfeeder! The action started with one up on the deck railing under the feeder and another 2 directly below on the deck floor. The one on the railing comes down almost on top of one that was on the deck floor. The one that was on the deck railing stayed in the video the longest…thoroughly searching under the feeder after going down to the deck floor.

Sycamore branch. Back on August 2nd I posted about a dead branch in our Sycamore tree (picture on the left). My husband discovered the branch on the ground near the base of the tree when he went out to use the weed eater and it took both of us to pulled it to our brush pile at the edge of the forest. It came down without bringing a lot of other branches with it….a little sooner than I expected but probably brought on by the thunderstorms that have been sweeping through the past few days.

Yellow wooly bear. My sister sent me a picture of a caterpillar from her garden in Carrollton, Texas. It appears to be a yellow wooly bear that becomes a Virginian Tiger Moth. Evidently, they are common but neither one of us had seen one before.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Identifying sources of deadly air pollution in the United States -- ScienceDaily – Focusing on fine particulates associated with heart attacks, strokes, lung cancer, and other diseases…about half comes from burning fossil fuels; the other half is from animal agriculture, dust from construction and roads, and burning wood for heating/cooking. Ammonia is one pollutant that is not regulated as much as the others and yet it causes a 5th of all deaths caused by fine particulates. It could be reduced with targeted manure management and improving formulations of cleaning supplies, paints, and inks, etc.

Free Technology for Teachers: 500+ Icebreaker Questions – These could also be used as writing prompts…they are good for a bit of self-exploration…useful even if you are not in as many groups right now.

Aztec Palace and House Built by Hernán Cortés Unearthed in Mexico City | Smart News | Smithsonian Magazine – History through layers of stone floors.

Biosignatures may reveal a wealth of new data locked inside old fossils -- ScienceDaily – Not DNA…chemical analysis (using non-destructive Raman spectral analysis) of products of degraded proteins, lipids, and sugars in fossils. Results group into 3 types of biosignatures: biomineralization, tissue, and phylogenic.

Infographic: What Social Isolation Can Mean for the Brain | The Scientist Magazine® - I wondered if the brain structural observations were a cause or effect (or neither). Does the observation that people who are lonely have smaller amygdalae because that are isolated or because they were born that way and it wouldn’t matter if there were a lot of people interacting with them…they would always feel lonely/isolated.

Top 25 birds of the week: July 2020 - Wild Bird Revolution – Always beautiful birds.

Innovative Birds Face a Lower Risk of Extinction | The Scientist Magazine® - Birds that are dropping nuts on roads, stealing burning candles to eat the wick, using bread to lure fish, and pecking open sugar packets…..coming up with new behaviors to cope with new aspects of their environment.

A Silk Road Renaissance - Archaeology Magazine – Many more commodities than silk on the ‘silk’ road: jade, glass, spices, metalwork, ceramic….and missionaries. And the Sogdians were the people that made it work from the 5th to 8th centuries. Panjakent, in modern Tajikistan, has been excavated since the 1940s; many murals have been found depicting myths, fables and everyday life of the Sogdians. In 755 a failed Sogdian coup against the Chinese emperor and thereafter incursion of Arabs from their west caused the culture to fade.

New Research Reveals Surprising Origins of Egypt's Hyksos Dynasty | Smart News | Smithsonian Magazine – Based on chemical analysis of skeletons from the Hyksos capital, the dynasty was likely the result of an immigrant uprising rather than a hostile outside invasion!

Weird and Unbelievable Facts About Earwigs – Entomological trivia…always fun.

Unique Activities for Yesterday:

Blue Jay Behavior.  There was a blue jay on the deck railing making noise….fluttering its wings…making eye contact with 3 or 4 other blue jays around at the time. Those other jays seemed to ignore the ruckus and flew away. Then the bird flew down to the floor of the deck to look for seeds. Maybe it was a fledgling wanting to be fed by the adults…but the adults were forcing the young bird to find its own food? I’m not sure…but I enjoyed witnessing the minute or so of action…whatever it was about. Maybe it was the same jay that tried to get seed from our bird feeder a few days ago (and failed).

Native Americans Crossed the Pacific Long Before Europeans | The Scientist Magazine® - Using DNA to find more definitive answers.

Forest Surprise: A Wolf Story – West of Flagstaff ---- probably a Mexican grey wolf male…trying to find a new territory and exploring a restored forest appealing.

See Archaeological Treasures Unearthed by U.K. Residents During Lockdown | Smart News | Smithsonian Magazine – The uptick in gardening and yard work leads to finding things in or on the ground…and then people having plenty of time to find out more about what the objects are. Something positive happening during the pandemic.

You Can Now Explore All 48,000 Panels of the AIDS Memorial Quilt Online | Smart News | Smithsonian Magazine – I was glad to see this online version of the quilt is available – complete with search and zoom. I found the square for a person that I’d worked with in the 1970s and saw him at IBM sponsored conferences in the 1980s. Our early career crowd was scattered all over the country by the time he died in 1993.

Eleven Awesome Owls from Around the World – Good pictures and a short summary characterizing each bird.

Turmeric could have antiviral properties -- ScienceDaily – It’s already one of the supplements I take…as an anti-inflammatory. This study points to it being anti-viral as well.

Stain Solutions | U of I Extension – A good reference although in recent years the laundry detergents and cold water often get stains out.

Top 25 birds of the week: Wild Birds - Wild Bird Revolution – Enjoy the beautiful birds!

Solar Will Kick Most of Texas's Remaining Coal Fleet Offline – Good news for air quality in Texas. Evidently the growth of utility-scale PV production is rapid changing the Electric Reliability Council of Texas (ERCOT) market.

Infographic: How Breastfeeding Protects Mothers | The Scientist Magazine® - Research about the mechanism behind the observation that women that breastfeed their children have reduced long term risk of developing type 2 diabetes.

Unique Activities for Yesterday:

Circular voids. I am starting a series of Zentangle tiles that have circular voids in otherwise dense tangles. I got the idea from some Mordecai Ardon paintings (slideshow on Internet Archive here) like Fatal Eclipse shown at the right. My first two tiles are below.

Compost bin. Between rain showers – I put on the boots I have for river field trips and got all my containers of kitchen scraps and spent flower stalks (mostly day lilies) out to the compost bin. It took 4 trips! There have been more things recently that produced more kitchen scraps than usual: fresh corn on the cob, cantaloupe, cabbage cores, and tough onion/leek tops. I’ve learned to save cucumber skins for use in smoothies so those get eaten these days and veggies like beets and carrots just get a thorough scrubbing rather than being peeled. I put all the new scraps on one side of the bin and then turned the other side over on top of it. I should deteriorate very rapidly.

Fresh flowers in the house. There are now small bouquets from the CSA cutting garden in my office and on the kitchen table. The one below is the one in my office. I like having flowers in my field of view! It’s a way I show kindness to myself.

Gleanings of the Week Ending July 18, 2020

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Listening to Silence: Why We Must Protect the World’s Quiet Places - Yale E360 – I realized after 9/11 that most of the modern world sounds at my house are from transportation: planes/helicopters and cars/trucks with occasional yard equipment. While we had a stay-at-home order with this pandemic, it became noticeable as well. There are still times when those noises are subdued or gone. I notice the bird songs in the early morning…when the other sounds don’t intrude. As we skew more toward electric ground transportation….the noise level will notch downward. I enjoy the natural sounds a lot more than our man-made ones.

Declining eyesight improved by looking at deep red light -- ScienceDaily – I wonder if this is something doctors will start prescribing!

Why your organs might reach 100 even if you don't - BBC Future – A summary of some current research areas re aging. There are a lot of different approaches with the primary goal of most being to extend healthy lifespan.  Even if different organs age at different rates…they are interrelated to the body they comprise.

Maryland offshore wind farm could become stop-over for migrating sturgeon, striped bass -- ScienceDaily – I live in Maryland….so this story grabbed my attention. Will the offshore windfarm become a rest stop for fish? And they will offer a convenient infrastructure for researchers to collect data.

Where Will Climate Migrants Go? – THE DIRT – It’s something to think about now. Some coastal cities are already experiencing more flooding even without unusual storm events…and people that can move will probably do so. Will climate trends weigh in decisions about where they move? The article talks about cities and towns in the Midwest that have experienced declining population becoming ‘receiver’ locations. I wondered if people that have discovered that they can work from home during the pandemic – and can continue to do so – will be freer to move to these new locations and still have the same employer! Otherwise there is the challenge of how to sync moving to a new place with a new job.

The chemistry of cats: Allergies, catnip and urine – Compound Interest – Evidently male cats produce higher levels of allergen and have smellier urine…unless they have been neutered.

Ways to keep buildings cool with improved super white paints -- ScienceDaily – White roofs should probably become the norm….it will be hot enough without the added heat island effect caused by a lot of man-made structures with dark roofs.

How humans are altering the tides of the oceans - BBC Future – It’s happening around the world. Dredging river channels and filling in coastal wetlands cause shifts in how tides interact with the land. And then there is sea level rise too. Some places cited in the article that have experienced dramatic change: Cape Fear River in North Carolina (tidal range at Wilmington has doubled since 1880) and the same is true for St. Johns River/Jacksonville Florida. Sacramento’s tides disappeared in the late 1800s because of silt but dredging brought them back and the Thames tidal range was 2 meters during Roman times and 8 meters by the Victorian age.

Meet the Mountain Chickadee – We have mostly Carolina Chickadees where I live in Maryland…this is their relative in the western US (mountains).

Ancient Maya reservoirs contained toxic pollution: Mercury, algae made water undrinkable in heart of city -- ScienceDaily – Mercury from pigments used on Mayan building. Cyanobacteria blooms that made the water smelly and toxic. Not pleasant for a city center!

Unique Activities for Yesterday:

Regenerative Landscaping lecture (via zoom). The lecture was about an hour and my big take away was about the huge environment cost of lawns…and the many dimensions of that cost. The one I hadn’t thought much about before was from the California Air Resources Board fact sheet on Small engines in California (small engines being spark-ignition engines in things like lawn mowers). Their fact sheet says: “In the early 2020s, however, total smog-forming emissions from small engines are projected to exceed those from passenger cars in the South Coast Air Basin because passenger car emissions will continue to decrease. By 2031, small engine emissions will be more than twice those from passenger cars.” For comparison – they show 1 hour of lawn mowing emits as much smog-forming pollution as driving a Toyota Camry 300 miles! This must be an issue in all areas where there is a lot of mowed turf grass – kike most suburbs. There are multiple ways to address the problem and the one discussed in the meeting was transitioning to less lawn or lawn that does not need to be mowed as frequently (or at all). Another way would be to transition to electric mowers and other yard equipment. Right now – the only gasoline powered equipment I have is the mower. I’d been thinking about an electric mower because I don’t like the noise and smell of our current machine. So - this overall air quality issue is just one more reason to do it.

Enjoyed a slideshow of Armand Guillaumin (1841 – 1927) paintings available on Internet Archive here. He was a French impressionist painter and lithographer.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Utah’s arches continue to whisper their secrets - GeoSpace - AGU Blogosphere – A study to measure arches to hone 3-D models from the Geohazards Research Group at Universe of Utah. The 30 second video of the model showing how Moonshine Arch moves is worth viewing.

Will the world be quieter after the pandemic? - BBC Future – I know I appreciate having a quieter environment; it’s an aspect of the pandemic that has been positive. The quiet is one of the things I like about my Prius Prime when it is in EV mode. Maybe some of the new norm will involve choices to maintain, as much as we can, the quiet.

Exposure to air pollution impairs cellular energy metabolism -- ScienceDaily – A study from Finland – exploring how particulates impact the olfactory mucosa (a neural tissue located at the upper part of the nasal cavity…the first line of defense against inhaled agents). As I read the article, I wondered if this is the tissue impacted my COVID-19 in people that lose their sense of smell when infected….and also, does wearing a mask filter enough particles to give the tissue a break from other air pollutants.

Renovations Reveal Rare Maya Murals Hidden in Guatemalan Home | Smart News | Smithsonian Magazine – From a colonial home in a mountain village.

Bird feeding helps females more than males -- ScienceDaily – The female cardinals are at my bird feeder much more frequently that the males in both winter and summer. This study doesn’t really point to a reason for that. I’ve always thought that other than the males dominance getting food first….the females might need more food at certain times….when they are laying eggs, for example.

London Foxes Show Early Signs of Self-Domestication | Smart News | Smithsonian Magazine – “Domestication syndrome” – shorter snout and smaller brain.

Painted Vault Revealed at Villa Near Pompeii - Archaeology Magazine – There are new discoveries because they are excavating a part that has not been studied before.

Marine Biologist Braves Cold Water to Photograph Little Known Sea Creatures – Creatures of the ocean….many so delicate they can’t be studied in a lab. Alexander Semenov is a marine biologist and photographer working like a 19th century naturalist, but with 21st century technologies.

Plot Brewing To Blanket US In Solar Panels + Pollinator-Friendly Plants – A beginning…. building hope via steps in the right direction. This article coincided with the MACCEC conference earlier this week. I ended the week more optimistic that the ball is in motion for many ‘drawdown’ actions.

Fish Eggs Can Survive a Journey Through Both Ends of a Duck – The study in this article was done with common carp and Prussian carp…. but what about other invasive species. If most types of fish eggs can survive the duck’s gut - it is bad news for efforts to stop the spread of invasive fish species.

Unique Activities for Yesterday:

Thinking about the first women in my family that could have voted. Women have had the right to vote in the US since 1920 – we’re celebrating 100 years this year. My sister and I have been talking about our great-grandmothers (and maybe the great-great grandmothers too). It’s interesting to think about what it was like in 1920 in our family; they were all citizens by then…although one side of the family were immigrants or children of immigrants.

We wondered if their relationship to immigration and obtaining citizenship would have made it more likely that they would have voted. One of them was divorced with her children teenagers or older; she was educated in Europe before she immigrated. Did her oldest son go with her to vote? The other great-grandmother might have voted as well; she had 3 daughters in 1920 with the youngest being 8 years old (there would be one more after 1920) and they lived on a farm…but went into town often enough. My grandparents from that side of the family always voted, so there’s a reasonable chance that their mothers did to.

One of the things I learned during the recent conversations, is that the grandparents on the other side of the family hosted the local polling place in their garage in the 1940s! That’s an indication that voting was important to them and that could have been passed down from their parents.  One of those great-grandmothers ran a boarding house (around 1920) so she was aware of things going on in town and would have had easier access to the polling place. She insisted that her daughter finish high school a few years later which might indicate that she was attune to the changing role of women more broadly.

I like to think that maybe all 4 of my great-grandmothers voted in 1920…their first opportunity to do so.

What if all viruses disappeared? - BBC Future – We are more aware of pathogenic viruses….but there are a lot more that are not pathogenic to humans….and are often beneficial (directly and indirectly).

Scythian Warrior's Genome Analyzed - Archaeology Magazine – Surprise! Discovered in 1988 and assumed to be a young warrior based on the weapons in the grave. DNA revealed it was a girl and was younger than 14 years old.

90 Percent of U.S. Could Be Powered by Renewables by 2035 - Yale E360 – Technically feasible…but do we have the determination as a country to do what we need to do for future generations?

Repetitive negative thinking linked to dementia risk -- ScienceDaily – But can training/therapy to reduce negative thinking reduce the risk? Whether it does or doesn’t – it seems that people who perceive the positives in their lives are more satisfied/happy….so teaching strategies to enhance that kind of thinking is probably worth it.

How Iceland is undoing carbon emissions for good - BBC Future – Examples of how Iceland is pushing the technical envelope for carbon capture even in heavy industry.

What Makes Some People More Resilient Than Others - The New York Times – Tools most common in resilient people: realistic optimism, a moral compass, religious or spiritual beliefs, cognitive and emotional flexibility, social connectedness.

Memory consolidation during REM sleep: Researchers identify neurons responsible for memory consolidation during REM sleep -- ScienceDaily – I remember the babies I’ve known well having frequent REM sleep….they are doing a lot of memory consolidation!

Top 25 birds of the week: Camouflage – They are easy to spot in these zoomed pictures….in the field, their camouflage is highly effective.

Urine test reveals quality of your diet -- and whether it's the best fit for your body – Interesting work. Maybe in the future we’ll get feedback from the toilet about the ‘health’ of our diet as easily as we get feedback about heart rate and sleep quality from wearable devises now.

The Winnowing of the Wilson’s Snipe – A bird that could fit in the camouflage group…but this bird is special – it makes sound with specialized tail feathers!

Unique activities for yesterday:

Three kinds of day lilies. I have three different kinds of day lilies blooming right now. I love having the flowers in my office and something new opening every day!

Ice maker repair. My husband ordered a replacement part for our ice maker once we started having water overflowing the unit and accumulating in the freezer. He’d done some research online and it seemed likely that the new part would fix the problem. It came and after a few days of the box sitting around to decontaminate, we pulled out the refrigerator to install it (using the opportunity to clean the floor too). This is the type of thing we would have called for repair service pre-pandemic. There are areas where we’ve become a lot more resourceful in recent months and I wonder if we’ll continue that trend post-pandemic.

Molecules that reduce 'bad' gut bacteria reverse narrowing of arteries in animal study: Promoting a healthy gut microbiome may be a powerful strategy for lowering cholesterol and other heart attack risk factors -- ScienceDaily – Eating differently could help…but eventually we might take ‘medication’ that helps us reduce or eliminate the unhealthy gut bacteria even if we are not as mindful about what we eat.

Study Suggests Human Relatives Were Genetically Compatible - Archaeology Magazine – Using genetic distance values to predict that hybrid offspring of Neanderthal and Denisovan would have been health and fertile…and thus explaining why modern humans have traces of their DNA.

Travelling for pleasure: a brief history of tourism – A little history lesson of travel…..more of a virtual experience right now rather than planning to travel anytime soon.

Just being in the outdoors. I ate breakfast and lunch out on the deck. It felt a little cool for breakfast – made worst by the very cold breakfast smoothie - and then warmer and muggy by lunchtime. This month I have been intentionally spending more time outside and broadening what I am doing there…it is not just about lawn work or hiking or nature photography…I am reading and interacting with the cat and writing blog posts (i.e. making the covered part of the deck a ‘room’ of our house). The point of it all is to just be outdoors. The only negative would be if I was allergic to something, but it seems that most of the pollen that bothers me is not around right now. All I am experiencing is the positive.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Why some older adults remember better than others -- ScienceDaily – The article seems to be more about the technology that enables these studies….hints at findings that may eventually be actionable.

The World’s Forests Are Getting Younger and Shorter, Research Finds - Yale E360 – This article is a little confusing. It says that ‘climate change is altering the age and structure of the world’s forests’….but it’s more than climate change. It’s also land use decisions (like logging , conversion to agriculture, introduction of invasive species) that have changed the forests. I was disappointed in the article although the last sentence seems obvious: “We as a human society are hitting these forests so rapidly with so many different changes that they can’t keep up.” Now the big question is – what are we going to do about it?

Remains of 60 Mammoths Discovered in Mexico | Smart News | Smithsonian Magazine – North of Mexico City.

Photographer Captures ISS Transiting the Sun in First Solar Photo Shoot – A challenge…requiring lots of planning, practice….and then success!

Top 25 birds of the week: LBBs - Wild Bird Revolution – Little brown birds…. they are everywhere.

Ancient Roman Mosaic Floor Unearthed Beneath Italian Vineyard | Smart News | Smithsonian Magazine – Finally returning to a site first discovered in 1922 and making this find within a week of starting excavations. The mosaic floor is well preserved a few meters below the vineyards surface and is thought to date from the 3rd century AD.

The Infant Gut Microbiome and Probiotics that Work | The Scientist Magazine®  - Evidently the infant microbiome has changed in the past 100 years…even among breastfed babies. And maybe that explains some of the immunologic problems in young children. There are indications that the probiotic helps babies nutritionally and immunologically.

Two bacteria allow spittlebugs to thrive on low-nutrient meals -- ScienceDaily – One of the bacteria uses aerobic glycolysis to process glucose to synthesize 7 essential amino acids plus 2 biproducts that the other bacteria uses to create ATP to produce 3 additional essential amino acids. It’s a similar two cell type process used by cancer cells.

An Encounter with Mating Gopher Snakes – Springtime out in nature…. this article from Idaho.

The gilded mummy of Lady Isaious | Egypt at the Manchester Museum – A Graeco-Roman Period mummy from the 1st century CE.

Unique activities for yesterday:

A large Zentangle tile. I printed a page (on card stock) from The genera of the plants of the United States illustrated by figures and analyses from nature by Asa Gray and Isaac Sprague published in 1848 available from Internet Archive.

Then I used the lotus as the ‘string’ for an 8.5x11 Zentangle tile. Like most strings….it mostly vanished. It took me about three days working for short periods of time to finish. Next time I’ll use more colors so that the botanical print ‘string’ remains more visible.

Gleanings for this week

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Volunteers Spot New Sites in Aerial Images of England - Archaeology Magazine – Volunteers and lidar scans…a productive combination!

Seven highlights from 70 years of the National Science Foundation - The Bridge: Connecting Science and Policy - AGU Blogosphere – Deepwater Horizon oil spill, public radio and television, ozone hole, strong curricula for introductory science, deep-sea exploration, student opportunities, and COVID-10 response. It seems like the list it too skewed to recent years.

We don’t need nearly as much protein as we consume - BBC Future – Another recommendation of getting nutrients from food rather that highly processed food or supplements….and moderation too. Skewing the diet toward protein at the expense of other nutrients is not healthy!

The Coolest Kingfishers from Six Continents – I’ve seen the first three! All three in south Texas and the Belted Kingfish elsewhere too.  Kingfishers are an easily recognized shape….heavy bill, bigger head relative to body…etc.

How Americans are coping with COVID-19 stress -- ScienceDaily – This report was prior to the additional stressor of George Floyd’s death….the racism of police evident in the videos of the event and the response to protests that seems too militarized. It seems like 2020 will be a pivot point in our nation’s history and how we all respond to the stressors of the year is important in the outcome. I hope that we can show the best of ourselves…our utmost caring for all people and our planet that is our home.

Ice Arch Persists Despite Warm Arctic – It won’t last long…the ice arch which prevents sea ice from drifting south generally breaks up in June or July. Last year it broke up in mid-April.

'New' Footage of Benjamin, the Last Tasmanian Tiger Ever Seen Alive | Smart News | Smithsonian Magazine – A 21-second video from 1935.

Top 25 birds of the week: Seabirds - Wild Bird Revolution – I’ve seen most the North American birds in these photographs….except for the puffins.

Babies know when you imitate them -- and like it -- ScienceDaily – Most parents probably realize this to some extent…but the research teases out more specifics about how babies respond to knowing they are being imitated.

The remarkable power of the prickly pear - BBC Future – Grown as a crop for food in arid areas and then using the waste left after the food is extracted to generate biofuel. Wish we had more processes like this.

Unique activities for yesterday:

Aftermath of thunderstorm. I did another early morning in the outdoors – noting the aftermath of the thunderstorm the night before. Both birdbaths had been filled by the rain. The one in front is surrounded by day lily leaves…I’m not sure how often it is used by birds, but I like the way it looks from our front door.

The sycamore tree trunk still looked very wet. I had forgotten the Virginia creeper climbing up. There were a few sycamore leaves that were blown into the yard…but the wind must not have been too bad.

The wetness of the leaves kept some of the maple leaves flipped over. It’s always surprising that the underside is so light in color.

Finally, I noticed a dead bee just before I settled into my chair. It must have gotten into the screened part of the deck and not been able to escape.

The rest of my outdoor time I spent making a couple of Zentangle tiles….and listening to the birds.

Mint as a fresh veggie. Mint grows so easily and comes back year after year. My front flower bed has a lot of it…enough to use it for more than a garnish. I cut a handful of stems and strip the leaves – it is the leafy green in a smoothie with chocolate protein powder. Yummy!

A Zentangle Prompt

Make a two tangle tile today with ROSCOE and SAND SWIRL.

Here is a tile I made yesterday based on the prompt: Three patterns to combine in a tile today: FAUX WEAVE, FEATHER FALL, and MEER.

Gleanings, MAELSTROM prompt, and a Phoebe

Continuing the blog post series prompted by COVID-19….

Gleanings from the Past Week

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

The world’s most nutritious foods - BBC Future – The one on the list that surprised me was ‘pork fat.’

New Thoughts on Corn Cultivation at Cahokia - Archaeology Magazine – Evidently maize arrived between AD 900 and 1000…about 1,000 years later than previously thought. I remember visiting Cahokia in 2010 about this time….a road trip from Ithaca NY to Flagstaff AZ with my daughter for her summer of undergraduate research.

Old Wisteria Tree in Japan Is the Most Beautiful in the World – I missed the wisteria blooming at Brookside Gardens this year. This 150 year old tree in this post is huge in comparison.

How the news changes the way we think and behave - BBC Future – I find that I feel better when I don’t check the news as often…once or twice a day is often enough unless there is something happening that impacts what I am doing (like very bad weather coming). I want to stay informed but don’t need stories repeated again and again…one time is generally enough and there are very few that I need to know as they are developing.

Top 25 birds of the week: #May 2020 - Wild Bird Revolution – A little feathery color….

Waves of Fluid Bathe the Sleeping Brain, Perhaps to Clear Waste | The Scientist Magazine®  - Still a lot to learn about the brain. I found myself wondering of poor sleep is the cause or effect of some disorders.

An Intimate Look at Italy’s Saffron Harvest - The New York Times – Color and flavor – and labor intensive.

Saber-tooth surprise: Fossils redraw picture of the fearsome big cat – The big cat was a forest/ambush hunter rather than one that hunted in more open environments.

Welcome Back! | The Prairie Ecologist – Noticing the firsts of spring….a bird returned…insects emerging (or sometimes returning), plants beginning to grow….lots to take in.

Medieval Arrows Inflicted Injuries That Mirror Damage Caused by Modern Bullets | Smart News | Smithsonian Magazine – The English longbow. The best ones were made from yew and measured 6 feet long. Drawing the weapon required 150-180 pounds of force. They shot arrows to 1,000 feet. At the Battle of Crecy in 1346, historians estimate that the English archers shot as many as 35,000 arrows per minute….were victorious even though they were outnumber by 2 to 1.

A Zentangle Prompt

Experiment with the MAELSTROM pattern. This is a grid pattern and is an opportunity to play with different orientations of a simple basic design made in each small square.  I always like to reuse materials I have around the house and an old calendar is great for these patterns. My calendar has large enough blocks for each day that I divide each into 4 x 4 grids and then cover the whole page (except for the small blocks that have a number in them) – in this case with MAELSTROM variations. I’ll share the results with you tomorrow.

Here is a tile I made yesterday based on the prompt: Make a tile with TRIPOLI as the central tangle.

Unique activities for yesterday:

Phoebe in the morning. I hear a phoebe almost every morning but usually don’t get a photograph. Yesterday I did…while it was proclaiming its name.

Small chipping sparrow. I’ve noticed a chipping sparrow that looks smaller than the others coming to the feeder the past couple of days. I finally got a picture of it with another chipper on the other side of the feeder. Doesn’t the one on the right look smaller? Maybe it is just the way the bird is oriented/holding itself.

Venturing Out and Weekly Gleanings

Continuing the blog post series prompted by COVID-19….

A Zentangle Prompt

Inspiration for a pattern can come from our environment. Sometimes creating a pattern is relatively straightforward. The prompt for today is to create your own pattern based on the picture of tiles to the right. Hint: start with a grid of squares. Use your pattern in a tile. Other patterns in the tile are tangler’s choice (i.e. whatever you want).

Here are some tiles I made based on yesterdays prompt: Make a tile using the gingo pattern.

It is one of my favorite patterns for mono-tangle tiles.

Venturing away from Home

I went to Howard Country Conservancy’s Mt Pleasant to record a Facebook Live Zentangle session. It was the first time I had driven my car in May! It was also my first volunteer gig since early March – and a good experience – but I realized how out of practice I have become with getting out and about. There was a ‘newness’ to my car even though I’ve had it for a few years. Mt Pleasant is a place I know very well but hadn’t been there since January; it felt unfamiliar.

I was glad the flip chart pad and gallery board were wrapped in plastic trash bags because it was raining heavily when I got there. It took two trips to get into the building and I was glad I had worn a windbreaker and waterproof boots.

The mask that I wore during set up did not stay in place as well as I wanted. I need more experience with securing it and being certain that I can breathe well enough through the layers of fabric. It’s a good ‘lesson learned’ before I venture out to try doing my own grocery shopping in June.

The materials I had prepared ahead of time worked well…minimizing the amount I had to create while I was talking.

The Facebook Live session lasted about 20 minutes and made a three-part tile using TIPPLE, CRESCENT MOON, and either MEER or POKEROOT. I missed not being able to create a mosaic of the student tiles at the end. Here are tiles I made with the patterns after the session.

I’m not sure how any of my volunteer gigs will be possible anytime soon but I’ll probably do some hiking at Mt. Pleasant…on a sunny day…another small ‘venturing away from home.’

Gleanings of the Week

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Soak in the Details of the Moon with this High-Definition Photo – A backyard astrophotographer with a lot patience.

Record conservation study of Tutankhamun's tomb solves mystery and raises new questions – Teasing out more history from a much-studied place.

Top 25 birds of the week: Bright Colours - Wild Bird Revolution – It’s a gray rainy day as I write this….I am appreciating the colors!

New Thoughts on Turkey’s Oldest Temple Complex - Archaeology Magazine – Gobekli Tepe…built by hunter gatherers over 11,000 years ago….requiring hundreds of people to construct. I first learned about it in a Coursera course a few years ago.

NASA's ICESat-2 measures Arctic Ocean's sea ice thickness, snow cover -- ScienceDaily – ICESAT-2 was launched in September 2018; I learned about it during visits to NASA Goddard during my HoLLIE class in spring 2018. It’s good to get an update on it now.

The ingredients for a longer life - BBC Future – Study of populations where many live to 100…focusing on eating habits, social connection, a few cups of tea or coffee, sweet potato and bittersweet melons, landscape…and moderation.

Saving energy and lives: How a solar chimney can boost fire safety -- ScienceDaily – If a building has a solar chimney, it will suck smoke out of a building during a fire…giving people more time to escape!

Risks of Clutter, Tips for Decluttering Your Home | Berkeley Wellness – I had intended to spend some of the ‘stay at home as much as possible’ time de-cluttering. But I moved on to other projects. Now I am returning to the idea just as I am beginning to tentatively venture out. The clutter in my house is not enough to make it unsafe…but I do have a lot of stuff that I no longer need.

Tracing the human genetic history: Every tooth tells a different story – Another data point for forensics when DNA is not available. Teeth often survive for longer than other parts of the body.

New evidence of watery plumes on Jupiter’s moon Europa - GeoSpace - AGU Blogosphere – I’m missing Charles Cockell’s Life in the Universe Pandemic Series. This article is about new analysis of data collected by the Galileo mission flyby of Europa in 2000.  The ESA Juice mission, which is scheduled to launch in 2022, will study the potential habitability and underground oceans of three of Jupiter’s moons: Ganymede, Calisto, and Europa.

Weekly Gleanings, Racoon Visits and Rearranging Office

Continuing the blog post series prompted by COVID-19….

(I’m still social distancing/staying at home as much as possible….but am changing the title of the blog posts to reflect the accumulation of topics in the posts. I’m tired of only the date changing in the title since March 15th, 2020)

Here are the unique activities for yesterday:

Racoon in early morning of 5/12…and then on 5/15! I was downloading the birdfeeder cam videos and noticed right away that there was an odd one just before 2 AM on 5/12….it was a racoon! It was a female probably hungry because she has babies still in the den – too young to eat on their own.  It didn’t appear that she got anything from our feeder.

We had another racoon visit on the 15th just after 2 AM. I couldn’t tell if it was a female or not. It could have been another racoon or the same one giving it another try. The animal used a different strategy to get the seed coming at the feeder from above rather than below….but the strategy didn’t work. It looks longingly at the feeder from the bench on the deck before it leaves.

Rearranging my office.  It’s a work in progress.  The room has been my office since we moved into the house in November 1994 – and it’s the best room in the house for an office because it looks out to trees. I bought the three-piece computer office tables from IKEA as we moved in and had them connected in an L until about 9 years ago when I wanted better access to the windows. I detached the longer table from the corner piece at that point. Then I detached the shorter table about a year ago so I could use the whole surface area of the corner piece…and now I’ve moved the small table by the window but pulled out a bit. When I am sitting at the small table, I have a clear view of the bird feeder. We’ll see how it works. I might not like it in the afternoon when the sun shines in and I need to close the curtains to keep the room from heating up.

And now for the gleanings from my news feeds during this past week….

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Check Out the Beautiful Flowers in Bloom at the Keukenhof – I missed going to Brookside Gardens this spring. I’m glad there are beautiful photographs like these and that we have the forest behind our house.

Researchers Reexamine Ritual Sacrifices in Ancient Mesoamerica - Archaeology Magazine – Evidently there is skeletal evidence that there were 3 distinct methods used for heart extractions.

Researchers Uncover New Evidence That Warrior Women Inspired Legend of Mulan | Smart News | Smithsonian Magazine – Not specifically Mulan but there is physical evidence that female warriors road across the steppes of what is now Mongolia around the 4th or 5th century AD which is about the time the first historical mention of Mulan appears.

Dolphins, Surfers and Waves Sparkle in Bright Blue Bioluminescent Glow Off California Coast | Smart News | Smithsonian Magazine – Dinoflagellates. Watch the two videos.

Top 25 birds of the week: Birds of Prey - Wild Bird Revolution – This group includes a Snail Kite – which we saw in Florida a little over a year ago. (I posted about it too!)

Nearly half of US breathing unhealthy air; record-breaking air pollution in nine cities -- ScienceDaily – I was surprised at some of the cities listed on the top 10 most polluted cities (short term particle pollution)…and the comparison of that list with the year-round list was interesting.

Cool Facts About Common Backyard Wildlife – The list includes racoons. Evidently racoons are usually very clever about accessing urban/suburban food sources. So far – the design of our bird feeder is working…frustrating the racoon.

Infographic: Building Bacteria to Fight Cancer | The Scientist Magazine® - Work being done in mice at this point…goal is to target tumors specifically and minimize side effects of treatment.

Paleontologists reveal 'the most dangerous place in the history of planet Earth' -- ScienceDaily – 100 million years ago the Sahara had flying reptiles and crocodile-like hunters!

Great Lakes Without Winter Ice – A picture taken from the International Space Station in February.

Filling a Day of Social Distancing - 5/8/2020 - Gleanings

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Coloring a flower picture. I found a wonderful book on Internet Archive – Flower Designs by Marcia Bradford. It is printed one flower per page with light lines. They were originally intended for watercolors. I selected the one that looks like a California Poppy first (saving the morning glory for another day); there are 18 flower pages to pick from!

View fullsize

View fullsize

I saved the page from the book as a jpeg then printed it on manila cardstock. I used a paper cutter to make ‘tiles’ (so that it would be a mosaic rather than one 8.5x11 inch page). I like the colored result. Tomorrow I’ll fill in some of the blank area with ‘tangles’!

Bringing in more iris stems. We had a freeze watch for overnight, so I cut two more iris stems yesterday. The others are not far enough along to bloom, so I left them outside and hoped they would survive the frost. I took the vase outside so that I could put the new stems into water right away with the stem I’d cut previously.

Unfortunately, I bumped the flower on the way back into the house so now the flower is in its own small water glass.

While I was out, I also cut more mint to use in my smoothie with the chocolate protein powder. It tasted so good last time that I’ve added the combination to my smoothie rotation. Hopefully, the temperature will not get down low enough overnight to kill the mint.

And now – the Gleanings for this week

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

One little Chipmunk on a Mission! – Pic for Today – Chipmunks are such fun to watch. We have had then periodically around our house but not all the time. They seem to like our front flower beds and porch when they are around. Squirrels are the constant in our neighborhood.

New PMEL Science at Work Video: How tiny particles affect air quality and climate | NOAA Pacific Marine Environmental Laboratory (PMEL) – The video as just under 4 minutes…. explaining how we learn about aerosol particles (important because the particles can impact health).

Image of the Day: Ancient Dental Enamel | The Scientist Magazine® - Quite a lot can be derived from protein sequence analysis these days.

Top 25 birds of the week: Endemic Birds - Wild Bird Revolution – Some birds native only to a certain place.

City of Houston Surprises: 100% Renewable Electricity — $65 Million in Savings in 7 Years | CleanTechnica – The city is planning to power all municipal operations with renewable energy! Also included in the program – the provider will help city employees purchase discounted renewable energy.

Organic food growers see surge in demand during pandemic - UPI.com – Glad the organic farmers are thriving. So far- I’ve been able to get organic produce in my grocery deliveries. My local Community Supported Agriculture farm will begin in June.

Understanding deer damage is crucial when planting new forests -- ScienceDaily – UK research on an issue we deal with in the US too.

Frozen, fresh or canned food: What’s more nutritious? - BBC Future – A little update. The article confirmed what I already knew…it’s good to know I don’t need to reset my thinking.

Analysis of Pompeii's Garbage Suggests the Ancient Romans Recycled, too | Smart News | Smithsonian Magazine – Evidently garbage was piled at city walls and sorted for reuse. They lived much closer to their garbage.

Wildflower Watching as a Source of Solace and Diversion – This is the time of year to find wildflowers. I am always surprised at how amazing even the tiny ones look when I can get close enough to photograph them.

Filling a Day of Social Distancing - 5/1/2020 - Gleanings

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Downloading Woody Plants of the Northern Forest by Jerry Jenkins.  The Northern Forest Atlas organization has 3 digital atlas guides: woody plants, mosses and sedges. They are available as free downloads (PDFs). The images are wonderful…the downside is that the guides are HUGE because of the high quality images. The woody plant guide is 630 MB. Put the download in a place you will remember to retain it as a reference (and avoid downloading it again).

Browsing the books illustrated by Frederick Richardson on Internet Archive. He illustrated books in the early 1900s. The samples below are from Edith Ogden Harrison’s The Enchanted House and Other Fairy Stories.

Walking laps. It’s been very wet here, so I’ve been indoors more. I’ve plotted various circuit paths through my house to get some exercise! I do laps for 5 or so minutes every hour…or that is the general goal.

Receiving a new office chair. My constant bouncing on the Swopper stool at my computer had recently started to bother my back rather than sustaining my back muscles….so I opted to move to a more traditional office chair. We had one that was over 30 years old that I thought might work but the height adjustment no longer functioned. My husband found a new chair from Staples…ordered it…and it came to our front porch within a day or so. It’s now assembled and will be the chair at my computer. The Swopper will still get used daily….but not as heavily as it has for the past 10 years!

Links to my previous “filling a day of social distance” posts  here.

And now for the weekly gleaning list….

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Deep Sea Squid Communicate with Glowing Skin: NPR – The video is a little over a minute…deep sea footage of Humboldt Squid taken by the Monterey Bay Aquarium Institute off the California coast.

To Cut Carbon Emissions, a Movement Grows to ‘Electrify Everything’ - Yale E360 – All-electric new construction…preparing the way for dramatic reduction of fossil fuel consumption.

Top 25 birds of the week: April 2020 - Wild Bird Revolution and Top 25 birds of the week: Blue Feathers - Wild Bird Revolution – A double dose of bird photographs this week!

Enjoy the Red-Winged Blackbird Show – I saw red-winging blackbirds on one of my walks in the neighborhood – at the storm water retention pond. There was a bit of drama I’ll share in a post next week.

The Hidden History in My Backyard – A history of a Florida backyard/neighborhood. I am content with the idea that my back yard was a forest….and that there is still a swath of forest down to the river.

Skulls from the Yucatan Peninsula a Clue to Early American Settlers | The Scientist Magazine® - Analysis of Quintana Roo skulls from people that lived 13,000-8,000 years ago…found in underwater caves that were above sea level at that time.

Pictures of Redwood National and State Park – Huge trees – always awesome.

Southwest Drought Rivals Those of Centuries Ago, Thanks to Climate Change - The New York Times – The last sentence is the bottom line: ‘We don’t have the whole story on Southwestern hydroclimate nailed down.’ The article talks about the analysis we have now….it probably means that the population growth in the Southwest happened at a time that was unusually wet, and that it won’t be supportable into the future.

Insect wings hold antimicrobial clues for improved medical implants -- ScienceDaily – Beginning to understand how nanopillar structures in cicada and dragonfly weeks kill bacteria on contact.

What chemical analyzes of human bones tell us about kitchen utensils in the Middle Ages - HeritageDaily - Archaeology News – Copper in bones….shows continuous exposure for cooper from AD 800 to AD 1800…consumed in daily diet prepared in copper cookware!

Filling a Day of Social Distance – 4/24/2020 - Gleanings

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Finishing Fashion as Design Coursera course. The theme for the last module was Expression. It was a good way to end the course. I have enjoyed both courses I’ve done from MoMA and will probably start a third one – What is Contemporary Art – early next week.

Hearing a piano practice. My husband opted to start up piano practice…not sure why he hadn’t thought to play it weeks ago. What’s not to like about a grand piano? It was tuned last winter just before the coronavirus pandemic, so it is in excellent condition. His playing didn’t last for long, because the cat demanded attention…and has decided that the best place to sleep is under the piano.

And then there are the gleanings for the past week:

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

How Rain Evolved Its Distinct Scent—and Why Animals and Humans Love It | Smart News | Smithsonian Magazine – The chemical that is the scent of newly moistened soil, geosmin, has been known to scientists since the 1960s….but now we are figuring out its purpose. It is made by 120 of 122 species of bacteria in the genus Streptomyces that have been studied. The scent attracts springtails (tiny arthropods) that eat the bacteria and spread the bacteria’s spores via their excrement or the spores that attach to their body and then fall off. Many other insects, fungi and nematodes are killed by chemicals produced by the bacteria. So – the scent after rain is connected to the lifecycle of bacteria that are one of the most important sources of antibiotics known to science!

Top 25 birds of the week: Terrestrial Birds - Wild Bird Revolution – Enjoying images of birds from around the world.

Long-living tropical trees play outsized role in carbon storage -- ScienceDaily – They used ‘hindcasting’ to validate their model: seeded the model with forest composition data collected at their site in Panama during the 1980s and then ran the model forward to see that it adequately represents the changes that occurred from then until now.  Once that was done…they can use the model to predict what will happen to the forest with climate change. Will the forest continue absorbing some of the excess carbon – or not?

Flamingos in Captivity Pick Favorite Friends Among the Flock | Smart News | Smithsonian Magazine – 2-4 birds…not limited to mated pairs. Some were together for the whole 5 years of the study! The study found no loners but some bounded between groups.

What do soap bubbles and butterflies have in common? Butterfly breeding gives insight into evolution of iridescence -- ScienceDaily – A 75% increase thickness in the chitin lamina of wing scales turned iridescent gold to shiny blue….the same way a soap bubble iridescence works! And now there is a whole new genetic approach to investigate structural color in butterflies – and may lead to new ways to produce photonic nanostructures for solar panels, paints, clothing, and cosmetics.

How to mine precious metals in your home - BBC Future – Theoretically - the “urban mine” is far richer in high value materials per ton than traditional metal ore mines….but we don’t quite have the way to collect the ‘ore’ or effectively extract the metals.  

Springfield Plateau: Cowbird Eggs – Cowbirds….I’m trying not to be too judgmental. (I’ve included a picture of cowbirds at our bird feeder below. The female is a more frequent visitor than the male.)

Colorful Image Lights Up Microscopic Guts of 'Water Bear' | Smart News | Smithsonian Magazine – Enhancing our view of a tardigrade with fluorescent stain….and done close to where I live at University of Maryland Baltimore County!

Take a Free Virtual Tour of Five Egyptian Heritage Sites | Smart News | Smithsonian Magazine – These are best viewed on your largest monitor!

Common protein in skin can 'turn on' allergic itch -- ScienceDaily – Turning off the production of the protein periostin in the skin can reduce the itch from atopic dermatitis (in mice). More research needed to see if it works for humans too.

Filling a Day of Social Distance – 4/17/2020 - Gleanings

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Browsing through some issues of Vogue. The Internet Archive has some issues of Vogue online. I particularly enjoyed the one labeled Vol 138: Vogue which includes issues from October - December 1961 (a bound reference volume); you’ll have to create a free-sign on to check it out – browse through. I was in 2nd grade when these issues were originally published and the designs appealing; maybe we all have a subconscious affinity for clothes that were worn as we were growing up. It was a time when natural fiber fabrics were being replaced with synthetic fibers. I can remember learning to iron my cotton shorts and tops during the summertime when I was in the later grades of elementary school!

Noticing filaments algae in the sycamore branch vase. How did it get here? Were there spores on the branch when I brought it in? The picture on the left below is looking down into the vase, the branch being the diagonal shape in the lower left corner. I pulled some algae out and put it on the top of my iPad (using the iPad as a light table) and took a picture through the jeweler’s loupe (picture on the right)…not enough magnification to see any internal detail, unfortunately.

Can fashion ever be sustainable? - BBC Future – This article fit right in with the Fashion as Design Coursera course I am working my way through right now. I already buy more than half my wardrobe from thrift stores and don’t buy very often. My closet is still too full; one indication is recently finding a pair of jeans I had forgotten about! This article has prompted me to think about how often I wash my clothes. Maybe I don’t need to launder some of them as frequently.

Why This Rare, Huge Ozone Hole Over the Arctic Is Troubling Scientists | Smart News | Smithsonian Magazine – It probably will close soon – but it’s an interesting phenomenon that probably would have gotten more press if coronavirus wasn’t overwhelming all other news.

Blood test detects over 50 types of cancer, some before symptoms appear -- ScienceDaily – This type of test has been a goal for years. Are we getting closer to reality?

Covid-19: The history of pandemics - BBC Future – The impact of coronavirus on our day to day lives is a unique experience for most of the world’s population. This article is a short history of  other pandemics: Justinian plague (6th century…killed as many as 50 million which was half the global population), the Black Death (14th century…killed up to 200 million), smallpox killed as many as 300 million people in the 20th century alone even though there was an effective vaccine available since 1796, 1918 influenza (50-100 million died), and HIV (killed 32 million and infected 75 million with more added every day). Since 1980, the number of outbreaks of new infectious diseases per year has tripled.

Here are the unique activities for yesterday:

Photographing the sunrise. I seem to get busy and miss the sunrise most mornings…but not yesterday!

Catching up on Charles Cockell’s Life in the Universe Pandemic Series:

• What is all this astrobiology?

• The astrobiology of the night

Noticing more sycamore leaves emerging. There are now three buds that have popped…lots of tiny leaves.

Making experimental face masks from materials I have at home….for when/if we need to go out. I made a mask with a paper napkin, small binder clips, the cut off top of a small gift bag (for the loops). The napkin would be replaced after each use…the rest sprayed with Lysol. It would probably fit better over the nose if I made some pleats. Even better using a scarf (or paper towels) and two hair ties/covered bands. (How to videos I watched). This is all about protecting others; I don’t want anyone to get sick if I happen to be an asymptomatic carrier.

Started Fashion as Design course on Coursera. The week 1 optional 2-hour video of 4 speakers and then Q&A (Under Review and then Reading) on the topic was well worth it.

25 Photos of Madeira's Dreamy Fanal Forest by Albert Dros – Calming nature. It is a quite different forest than the one I see from my office window. Both views are much appreciated.

Tips for how to stay happy in troubling times - BBC Future – Hopefully, some of these work for you. I find that limiting the time I spend catching up on ‘news’ is the one I need to keep reminding myself about; it’s so easy to get absorbed in all the pandemic news (none of it good). I want to be informed but not 24/7.

Monarchs Covered 53 Percent Less Area in Mexico this Winter | The Scientist Magazine® - The last paragraph of the article was the worst news: “The butterflies have already begun their journey north but there is not enough milkweed in Texas to support the butterflies’ reproductive cycle this spring.”

How your personality changes as you age - BBC Future – It seems like there are a lot of positive general trends in personality as we age: more altruistic and trusting individuals, willpower increases, a better sense of humor, more control over emotions. They’re calling it ‘personality maturation’ and it continues until at least the 8th decade of life! And its observed across all human cultures.

Top 25 birds of the week: Eagles - Wild Bird Revolution – Never can resist the birds….

On This Scorching-Hot Exoplanet, a Forecast of Molten Iron Rain | Smart News | Smithsonian Magazine – 640 light-years outside our solar system

Tour A National Park from The Comfort of Your Couch -  Hmmm….I’m going to start working my way through the virtual tours….Maybe one a day?

Unprecedented preservation of fossil feces from the La Brea Tar Pits: A 50,000-year-old Snapshot of Los Angeles trapped in asphalt -- ScienceDaily – The La Brea Tar Pits have been studied for more than a century….but apparently there are still things to learn from them. Fossilized rodent pellets found in context (so definitely not modern, they also were radiocarbon dated to ~50,000 years ago). They are preserved along with twigs, leaves and seeds….an intact woodrat nest!

Massive Mammoth-Bone Structure Found in Kostenki, Russia - Archaeology Magazine – A circular structure about 41 feet in diameter…made with bones from at least 60 mammoths.

Tree Tapping Isn’t Just for Maples – The 2020 season is over for getting sap from trees – this is still an interesting article about how it is done…and other trees that also have sweet sap. I was surprised to see sycamore on the list.

Tree Rings, Wildfires, and Climate | The Scientist Magazine® - Evidently the linkage between winter precipitation and fires in the spring in California – long documented in tree ring studies – has disappeared. Wildfires now are as likely to happen after a wet winter as they are after a dry one.

New Research Shows Healthy Agriculture Means Healthier Birds – Honing our understanding of healthy agricultural schemes that promote healthy farmland birds.

How cutting your food waste can help the climate - BBC Future – Over the past few years, I have started composting and reduced my food waste by eating food – never forgetting what I have in the refrigerator. Keeping a mental inventory of fresh fruits and veggies…freezing anything that I might not use before it goes bad….has been key. I enjoy frozen bananas in smoothies more than the unfrozen! This time at home (social distancing) gives me an opportunity for another round of reducing food waste….although it’s harder now since I’ve done all the easy actions.

'Grand Challenge' review stresses global impact of microplastics -- ScienceDaily  - Where major research and discovery are needed re microplastics impact on the environment and health. Recognizing that all plastic is not the same and new tools will be needed.

20+ Photos of a Snow-Covered Winter Wonderland in the Forest and 15 Incredible Finalists of the Smithsonian Magazine Photo Contest – So many beautiful pictures. I needed the boost of natural images this week.

Dragonflies are efficient predators: They consume hundreds of thousands of insects in a small area -- ScienceDaily – Exploring predation in the insect world…its impact on prey species and the community.

A Naturalist’s Guide to the South African Cape – Some unique species.

Top 25 birds of the week: Migratory birds - Wild Bird Revolution – I always enjoy the 25 bird pictures each week.

Sinking ships to stop erosion - The Landslide Blog - AGU Blogosphere – The example shows ships sunk after World War I to stop erosion…and now more than 100 years later – it’s obvious that it worked!

Staying in? Keep learning with science activities that kids and families can do at home | National Oceanic and Atmospheric Administration – Some resources from NOAA….ocean and atmosphere topics to explore without leaving the house!

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.  

Can Destroying Senescent Cells Treat Age-Related Disease? | The Scientist Magazine® - Lots of trials going on…this may be a way to extended years of healthy life (not elongate life).

This 'Blood-Red' Snow Is Taking Over Parts of Antarctica | Smart News | Smithsonian Magazine – I remember seeing snow that was the color of watermelon in Colorado…it’s algae Chlamydomonas nivalis, which is the most common type of snow algae around the world. It hasn’t been as common in Antarctica until this year.

Spotted Zebras, Yellow Cardinals, and Three-Antlered Deer: What Causes these Animal Oddities? • The National Wildlife Federation Blog – Some uncommon forms of animals we all recognize.

What Makes a Venus Flytrap Snap | The Scientist Magazine® - It’s complicated…and nuanced so that the plant only invests in digestion efforts when there is food!

Just a Tiny Fraction of America’s Plastic Can Actually Be Recycled, Report Finds - Yale E360 – We can’t send it to China any more…so it’s all on us to clean up our own mess. Unless and until we can get recycling working well…it’s important for all of us to reduce our use of plastics as much as possible. It’s hard to do.

States with highest rates of melanoma due to ultraviolet radiation identified: Several landlocked states among those with highest rates -- ScienceDaily – It’s not all about being out in the sun either. The prevalence was higher in younger females due to tanning bed usage by teen girls in the late 1990s contributing.

Interactive Infographic: How Salt Transforms Coastal Forests | The Scientist Magazine® - We noticed this process as we’ve visited Blackwater National Wildlife Refuge over the years. There are some areas that used to be marsh with some trees that are now open water.

Top 25 birds of the week: March 2020 - Wild Bird Revolution – No birding festivals in our future near term….but still enjoying pictures taken by others.

Why your internet habits are not as clean as you think - BBC Future – A good compilation of studies about energy consumption for various aspects of our online activities….maybe we can skew toward the lower energy use ones more frequently. Some of the energy, we pay for in terms of our electricity use….others are embedded in products or services we use where the energy usage is not something we see directly.
