Top 25 birds of the week: September 2021 – Such a variety of birds in the world!

The Love Stories of Sleepy Lizards – An Australian lizard…they are monogamous and have a surprising threat display. They have been studied for over 40 years.

Searching for the Fisher Kings – The Calusa of south Florida…a capital on a man-made island made of shell. Surviving the Spanish but not the British.

New Coal Plants Dwindle Amid Wave of Cancelled Projects – Good! We need to be ramping up generation of electricity with renewables….and dramatically reducing the methane released by the oil and gas industry in their extraction processes…and then begin to reduce our need for oil and gas in areas that can be electrified (like transportation and heating/cooling).

Explore Life Under the Microscope with the Winners of the Nikon Small World Photomicrography Contest – Photomicrography frequently creates art from reality that it too small for our eyes to see without the magnification and specialized equipment.

August 2021 global climate summary – From NOAA. Two global maps (temperature and precipitation). Where I live, August was hotter and slightly wetter than the average (averages from 1981-2010 for temperature…from 1979-2020 for precipitation).

People synchronize heart rates while listening to stories – Thinking about the brain as part of physical body….looking at the brain-body connection more broadly.

Study Links Transportation Noise to High Rates of Dementia and Alzheimer's – From Denmark.

Indigenous Resilience Center Launched at the University of Arizona – My daughter did her graduate work at University of Arizona; I’m glad they are launching the center to find and implement culturally appropriate solutions to the challenges of climate change.

The chemistry of dahlia flower colors – Also explains why there are no blue dahlias.

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.

Young female black bears in Asheville, North Carolina, are big, have cubs early – More research needed…it’s still not known what is causing them to be so much bigger and mature early…or if the population is increasing or not. It is clear that there are quite a few bears and lots of opportunity for interactions between people and bears – many not healthy for the bears.

The alarming risks of mixing common drugs – It is a problem that is acute in most elderly patients with good medical care. Their various doctors have gradually built up the medications…and the regime to take them all appropriately becomes daunting. Hopefully it will become best practice to constantly review and minimize drugs that are prescribed.

Work Of First African American Painter With International Reputation Explored – Henry Ossawa Tanner (1859-1937)

Hummingbirds can smell their way out of danger – I was thinking a lot about hummingbirds this past week after my success photographing one at Brookside Gardens.

Praying Mantis – I see these more frequently in the fall…but not every fall. There are so many mantis egg cases, there should be plenty to see; I need to improve my observation skills.

How much energy do we need to achieve a decent life for all? – The most important take away from this study: “energy for eradicating poverty does not pose a threat for mitigating climate change.” That is good news

The lost generation of ancient trees – The ancients are dying….and there are not enough trees old enough to replace them. There are various ways being tried to veteranize younger trees so they can play the role of ancient trees in ecosystems.

Fall Armyworms are Attacking Lawns and Crops on an ‘Unprecedented’ Scale – Hmmm…maybe this is a prompt to reduce or eliminate the grassy portion of the yard.

Mammoth Cave National Park: The World's Longest Cave Is Longer Than Before - 8 more miles mapped bringing the total to 420 miles!

Hand pollination of crops is of major importance – I was surprised that hand pollination is already used for important crops like apple, palm oil and cocoa.

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.

Wind Energy Accounted for 42% of New US Power in 2020 – And solar was 38% of the new energy. And 8 east coast states have large offshore wind projects in the works in the years ahead. Hurray! It’s a good trend and it looks like the slope of the trend will keep increasing for wind and solar (decrease and go to 0 for new natural gas).

How people respond to wildfire smoke -  Another reason to slip on a mask.

Devastating Rain in Tennessee – A map of the change in soil moisture between August 20 and August 21. The floods on August 21 in Tennessee (area circled on the map) killed at least 22 people. I was surprised that there was an area of Illinois (to the north and a little west of the flash flood circle) where the soil moisture increased even more; perhaps that area floods frequently and the area is managed with flooding in mind.

New analysis reveals Vesuvius Victims’ diverse diets – From analysis of Herculaneum skeletons. Men got more of their protein from seafood. Women ate more meat grown on land, eggs and dairy products.

Eye provide peek at Alzheimer’s disease risk – Amyloid plaques can form in retinas of the eye. Does their presence there provide a visible biomarker for detecting Alzheimer’s risk?

Top 25 birds of the week: Wild Birds! – Bird photography…..challenging and beautiful subjects for our cameras.

Have you seen a weasel lately? – There is a suspicion that weasels are in the decline…but the data is circumstantial. These are not predators that have been widely studied. The post points to a role for citizen scientists!

Dispatches from a world aflame – Reviews of two books about the recent fires…and the relation to climate change.

Preemption of Green Cities in Red States – At a time when we need to get serious about addressing climate change – a drive by some states to keep local governments from taking any action. There is a cognitive dissonance between historically arguing for local control then usurping that control when the state government does not agree with it. I like local control but acknowledge that higher up the governance hierarchy could make sweeping changes easier. Perhaps some of these state governments will redeem themselves by quickly taking strong action toward climate change reduction and mitigation – soon. The top issue for me when I vote these days has become climate change!

Climate Change Is The Greatest Threat To Public Health, Top Medical Journals Warn – Another reason that actions to address climate change must be at the forefront of our thinking about the future. Medicine cannot make up for the injury we are making to ourselves and every living thing on the planet.

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.

Entomologists Eradicated the First Asian Giant ‘Murder’ Hornet Nest of 2021 – Includes a picture of the 9 layers of the nest that was carved into an alder tree’s interior.

Turning thermal energy into electricity – It seems like this type of electricity production would have application beyond the military. Even solar panels produce heat and finding a way to automatically harness that into more electricity would be a good thing.  

Climate Change Producing More “Fire Weather” as Far East as Oklahoma – It’s not just the west coast that has a higher risk for fire as the planet gets hotter.

Aztec Pictograms Are the First Written Records of Earthquakes in the Americas – One of the pictograms matched to a 1507 earthquake that coincided with a solar eclipse!

Food systems: seven priorities to end hunger and protect the planet – A thoughtful commentary re ending hunger and improving diets; de-risking food systems; protecting equality and rights; boosting bioscience; protecting resources; sustaining aquatic foods; and harnessing digital technology.

Eating walnuts daily lowered 'bad' cholesterol and may reduce cardiovascular disease risk – There was a similar article about pecans a few days ago. I’m glad I like both walnuts and pecans! However – ½ cup is a lot to eat in one day. Usually ¼ cup is considered a serving.

Top 25 birds of the week: Woodpeckers! – I always enjoy hearing a woodpecker in the forest…and its a special tree to see them in our yard. The piliated, downy, and red-bellied woodpeckers are native to our area.

How to fight microplastic pollution with magnets – Many people filter their drinking water…but the conversation about filtering microplastics is newer. Hopefully filters that are effective and affordable will become the norm. It will take a long time to reduce the microplastic load already in the Earth’s water. We are just not recognizing the damage they are causing.

Americans Moving to Disaster-Prone Areas, Despite Climate Change – I’ve started to think about this more recently so appreciated seeing this post. Taking climate change into account – why would anyone buy property in areas that will be increasingly flood prone or incredibly hot/dry? A house nestled in a forest may look appealing but there are an increasing number of people that have already experienced the hazards of that beauty.

1,800-Year-Old Flower Bouquets Found in Tunnel Beneath Teotihuacán Pyramid – I visited Teotihuacan in the spring of 1966 when my parents took me to Mexico City. It was one of the highlights of the trip. The new discoveries are interesting….and I am thinking about whether I would like to see it again. Maybe in spring of 2026? The article references a site with some great pictures of Teotihuacan – worth a look.

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 subtle influence of the moon on Earth’s weather – Tides….and a lot of complex interactions associated with them. High tide flooding will increase as the climate changes for example.

So much ice is melting that Earth’s crust is moving – When the weight of ice is removed, the land lifts upward…but new measurements show that it moves horizontally as well.

Top 25 birds of the week: Spiderhunters and Sunbirds! – Lots of colorful feathers in this group!

Pecan-enriched diet shown to reduce cholesterol – 470 calories per day is a lot of pecans more than ½ cup. I like pecans but will generally stick to about ¼ cup at a time…may skew toward eating pecans over other nuts although walnuts are a healthy choice as well.

California Drought Hits World’s Top Almond Producer – And maybe almonds are a nut that will be increasing in price…maybe driving people away from almond milk. I’ve already made my switch to lactose free milk.

Northern paper wasps recognize each others faces – Each face is unique!

Giant clams have a growth spurt – thanks to pollution – Evidently modern clams grow faster than ancient ones because of nitrates in the water. It doesn’t necessarily mean that are healthy…just that they are growing faster.

Photography In The National Parks: Fun Fact Photography, Part 2 – The post not only includes ‘fun facts’ about the National Parks – it also explains how the images were captured!

What happens to your brain when you give up sugar – A well timed article for me --- I am dramatically reducing refined sugars and artificial sweeteners in my diet (i.e., I still eat foods that are sweet like bananas).  I thought the headaches that occurred in the first week of my new diet were the simultaneous reduction in caffeine but maybe they were also caused by the sugar reduction.

Watch a bolt of lightning strike the Washington Monument – The monument is on a hill and the tallest thing around…..a conduit to the ground for lightning.

Gleanings of the Week Ending August 21, 2021

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.

Nine things you should know about sea horses – The males give birth! Like many creatures right now – they are in trouble from climate change (and overfishing in some parts of the world). Not long ago – I learned that there is a species of seahorse native to the Chesapeake Bay. They live in sea grasses and estuaries…habitats that are in trouble.

Electric cars and batteries: how will the world produce enough? – One of the important steps that needs to ramp up as batteries (and solar cells) reach end of life – is recycling. We need to think about closed loops for the resources required to manufacture future renewables!

New analysis of landmark scurvy study leads to update on vitamin C needs – An example of the research behind how those ‘daily requirements’ of vitamins and minerals were developed. I wonder if more of the values need to go through a validation…how many would change just as the vitamin C requirement did.

Top 10 Grassland Species Across the Globe – The ones we have in the US are Long-billed Curlew, Black-footed Ferret, Pronghorn, Swift Fox, and American Bison.

The multi-billion dollar giants that are melting away – Glaciers. When they are gone…many parts of the world will be drier places. This article is primarily about central Asia…but the situation in South America is similar.

Loss of biodiversity in streams threatens vital biological process – Fungi and bacteria can’t do the decomposition job alone…the aquatic insects (often larvae) and crustaceans are needed too. And the populations and diversity of those organisms in our streams is declining.

Top 25 birds of the week: plumage! – Bird photographs…always colorful and interesting.

Gender revolutions in who holds the purse strings – The study was done in Britain…I wonder if similar (or different) changes are happening elsewhere in the world.

‘Polluter pays’ policy could speed up emission reductions and removal of atmospheric CO2 – A change that could speed up the transition we need to make…if we can somehow overcome the lobbying for the status quo trajectory.

Photography In The National Parks: Fun Fact Photography – This is a kind of photography you can do in lots of places. A little curiosity and a camera…some web searches…a neat cycle of learning/art that can turn again and again.

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 your phone battery creates striking alien landscapes – Lithium….needed for batteries that are needed for so many things (not just phone batteries).

Why do house finches love your hanging plants? – These birds are frequent visitors to our feeder. Based on the crowd we are seeing now – they’ve had a very successful breeding season…lots of young birds.

Ultraprocessed foods now comprise 2/3 of calories in children and teen diets – This article prompted me to look at what ultraprocessed foods I am eating…and making some changes. I am keeping the 1st breakfast that includes 90 calories of dark chocolate…but all the other ultraprocessed foods are going to become occasional or rare in my diet.

Tracking the Restoration of the River of Grass – An interview with Eric Eikenberg, President of the Everglades Foundation. There is a lot of work coming to fruition this decade in restoration of the Everglades…some positive news from Florida. It was an encouraging article but after reading the whole thing, it still seems to me that climate change will be a continuing disaster for Florida.

Red Tide Rages Along Florida’s Gulf Coast – On a more pessimistic note about the environment in Florida right now…

Top 25 birds of the week: August 2021 – Birds….so many different kinds to see.

Crawling with crickets: the insect swarm in the western US – Mormon Crickets (really katydids) have population crescendos in 3 of every 10 years in the west. The occurrences are patchy but damaging for some crops.

Music in the American Wild – I watched the Missouri Music at 200 webinar this week and am now looking at more of the concert videos from the ensemble. I’ll post the “Missouri Music at 200” webinar video address (when it is available on YouTube). Of course – live performances would be even better. I enjoyed the Hawaii 2020 project videos already…lots of good views of the island (particularly birds and volcanos!).

The ancient Persian way to keep cool – We’ve had quite a few heat advisory days recently…will probably have an increasing number every summer. The world will need to implement the most efficient strategies available to keep people cool.

Camera Trapping As Mainstream Nature Activity – Little cameras in the wild…they are probably less obtrusive than a human being in the place all the time…but not totally benign in every place.

A roadrunner taking a dust bath wins the 2021 Audubon photography awards – This gleaning list is big on bird photos! This is the first one.

Top 25 birds of the week: Conservation – This is the second. These posts encourage me to get outdoors in areas near my home to photograph birds!

How giraffes deal with sky-high blood pressure – Multiple differences between giraffes and humans when it comes to blood pressure!

Permafrost Thaw in Siberia Creates a Ticking ‘Methane Bomb’ of Greenhouse Gases – The article is about what happened in summer 2020…made me wonder about what is happening this summer in Siberia. This along with the fires that seem to be worse each season are signs that climate change is happening faster than anticipated…that the models might be optimistic rather than realistic.

Plastic, the Trojan Horse – A study that found plastic accumulation in foods may be underestimated. Not good.

Smoke Across North America – Lots of fires this summer. My husband told me that the local astronomy club has cancelled several nights they’d planned for observing because no stars were visible through the haze here in Maryland.

How the sun affects our skin – An infographic about vitamin D, sunburn and skin cancer.

This catfish doesn’t just move on land, it reffles – Plecos – from the aquarium trade – are now invasive in warmer waters in the US. They do have an interesting way of moving on land (videos of their reffle)…..this means if found/caught they shouldn’t be left on the bank to die (since they will easily move back to the nearest water). The article didn’t say what to do with them (presumable kill them).

Drought, Heat Taking a Toll on National Parks in Southwest – I’ve enjoyed so many of the parks mentioned in this article – Saguaro, Grand Canyon, White Sands, Petrified Forest. It has always been dry there…but now it is getting drier and hotter.

Take a Virtual Tour of Artworks Inspired by Efforts to Preserve Plant Biodiversity – A virtual site of an exhibit not at the Royal Albert Memorial Museum and Art Gallery in Exeter, England. Watch the 5 minute video about the site….then enjoy the exhibit here.

Climate Change Responsible for Recent Decline of Eastern Monarch Butterflies – I know that the milkweed in my Maryland yard is not as healthy looking and I don’t see as many butterflies as I did in the 1990s…it’s a sad trend.

Top 25 birds of the week: July 2021 and Perching – A special treat – two collections of bird photographs in this gleanings post!

The parenting penalties faced by scientist mothers – There are no single or quick ‘fixes’ – moving forward requires thoughtful approaches. The status quo is not acceptable or sustainable!

True Grit: Adventures in Red-Cockaded Woodpecker Research – My husband and I saw red-cockaded woodpeckers in Florida during a birding festival field trip…so I tend to look at articles that appear in my news feed about them.

Florida Breaks Annual Manatee Death Record In First 6 Months Of 2021 – Florida seems to be a less appealing place to visit these days. Manatees were an animal my husband and I always wanted to see there and now they are starving to death because the seagrass (their food) is dead or dying in polluted waters. Other animals are probably impacted as well.

Chaco Culture National Historical Park: Hard To Reach, Filled With The Unexpected – I’ve only been to Chaco Canyon once….in the spring when it wasn’t overly hot. There were not many people on the windy, cool day we were there. The sounds of the place increased the sense of history in the ruins.

Air pollution during pregnancy may affect growth of newborn babies – There are so many aspects of the human impact on our environment that overwhelm what our bodies can handle…we should probably assume that there will be health impacts – particularly noticeable in the very young and the very old.

Burrowing Owls Face an Uncertain Future – They need holes from small colonial mammals….areas that are not plowed.

U.S. Power Sector Sees Biggest One-Year Drop in Emissions in More Than Two Decades – Picking up the pace as more renewables come online.

‘Inflammation clock’ can reveal body’s biological age – Maybe this turns out to be a good diagnostic to prompt interventions to extend healthy lifespan (via treatments on specific types of inflammation).

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.

Night Sky Celebrations Across the National Park System – We’re not doing this kind of traveling this summer….but maybe we’ll do several of these ‘star parties’ in summer 2022.

Tooth loss associated with increased cognitive impairment – Another reason to not neglect going to the dentist! It’s not just about preserving cognitive impairment either….quality of life is a big motivation as well.

Top 25 birds of the week: Seabirds – From around the world…a few I’ve seen in North America.

Mucus and mucins may become the medicine of the future – There is still a lot to learn about how this might work….but it appears that this is an opportunity to treat disease by enhancing the mechanisms already used by the body. Maybe one of the first uses will be for eye drops to treat eye infections rather than the antibiotics used today.

Protect Pollinators – reform pesticide regulations – Hopefully the action requested by these scientist from around the world will happen…our ecosystems are having enough challenge dealing with climate change. Many pollinator species won’t survive the continued threat of status quo pesticide use.

Keeping your composure: Creative Ways to Compose Your Photographs (part 1, part 2, part 3) – Always good to browse through these kinds of tutorials…pick up some new ideas, celebrate the things you are already doing.

What to do with food waste? – It doesn’t appear than there is any one strategy that will work broadly. I’m glad I have already dramatically reduced food waste and then have a large enough yard to have a compost bin.

Waterfalls of North Carolina – A few years ago, my husband and I made a waterfall themed trip to New York. It seems that North Carolina would be another state that has a lot of opportunities for waterfall photography. Maybe next spring?

Creativity Myths – A recent ‘letter’ on The Painter’s Keys website.  I enjoy the twice-weekly blurbs that appear in my inbox (free subscription) and often follow the ‘click here to read more’ link.

Exposure to light with less blue before sleep is better for energy metabolism – I already change the color balance on my PC screens to ‘nightlight’ between sundown and sunrise. Maybe we will do more eventually based on this and subsequent research. It is probably true that no one should be watching a television screen just before going to bed!

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 'Zoom Boom' Can't Save the Midwest – People are leaving dense, high-cost urban metro areas…but very few of them are going to the heartland.  Maybe some of the areas will benefit from migration because of climate change. Or maybe the Midwest should simply focus on investments to help their economies and create places people want to live….do the groundwork to encourage people to move to the region.

Poison Mushrooms: How to Tell – From the Natural History Society of Maryland…good pictures.

The Avenues of America – An overview picture of Washington DC taken from the International Space Station.

The Invasion Of The National Park System – Quagga mussels, Burmese pythons, feral swine, household pets gone wild, tamarisk trees….and those are just the ones pictured!

Incredible Footage of Iceland’s Fagradalsfjall Volcano – And there are people in many of the pictures to provide scale!

Major advance in fabrication of low-cost solar cells also locks up greenhouse gases – There are so many articles about technologies that sound promising toward creating faster pathways away from fossil fuels….hope a lot of them move forward.

Elephant Trunks Can Suck Water at 330 Miles Per Hour – Wow

Pyramid made of dirt is world’s oldest known war memorial – Located in Syria…and at least 30 people – male and presumed to be warriors – buried in horizontal steps.

COVID-19 pandemic has been linked with six unhealthy eating behaviors -- ScienceDaily – Eating disorders are one of the deadliest psychiatric health concerns and 6 of them have a correlation to the pandemic: mindless eating and snacking, increased food consumption, generalized decrease in appetite or dietary intake, eating to cope, pandemic related reductions in dietary intake, and re-emergence or marked increase in eating disorders.

How flooded coal mines could heat homes – Evidently the water in the mines could be tapped as a source of geothermal heating/cooling!

Fibromyalgia likely the result of autoimmune problems – Maybe this change in thinking (neurologic to immune system) will improve diagnosis and management of the disease.

How freezing changed the green pea – A little food history

Massive Antarctic Lake Vanishes in Just Three Days – A lot can be learned with observations from space…and once we see something interesting like this there is historical imagery that can provide a view from past years too.

Tuberculosis: The Forgotten Pandemic – The search for a better vaccine for TB….some history of the past 100 years of TB around the world.

Top 25 birds of the week: Bird Interactions! – Birds with others…of their own species and sometimes another bird species.

The Finalists of the Bird Photographer of the Year 2021 Are Announced – Just found this post that came out back in April…enjoy a double dose of bird photos in this gleanings list.

Photos of the Week – June 17, 2021 – Spider photos from The Prairie Ecologist

Fire Destroyed 10 Percent of World’s Giant Sequoias Last Year—Can They Survive Climate Change? – Very sad….and this year there could be more fires.

6 Surprising Tales of Predatory Birds – The 6 birds featured are: pelicans, great blue herons, turkeys, crows, kelp gulls, and vampire finches.

Coelacanths may live nearly a century, five times longer than researchers expected – An ancient form of fish that evidently lives a long time, reaches maturity at about 55 years old and gestates offspring for 5 years. This slow life history has implications for conservation of the fish. I also wondered how many other species we know only from fossils had slow life histories compared to organism we observe today.

Top 25 birds of the week – June 2021! – The first picture startled me – a bird with a turquoise beak!

Beach Safety Tips: How To Avoid Being Bitten or Stung This Summer – I’m don’t go to the beach frequently…and then am usually more interested in shells and ghost crabs than being in the water! Still – the safety tips were interesting.

Concrete: The material that defines our age – With the collapse of the reinforced concrete building in Florida….this story seemed particularly timely.

Edible Cholera vaccine made of powdered rice proves safe in phase 1 human trials, study suggests – Reminded me of distribution ease of the polio vaccine sugar cubes back in the 1960s. In this case the special rice is powdered and sealed in aluminum packets that are then mixed with 1/3 cup liquid and drunk. Hopefully, the subsequent phases of the trials will be successful…it could save a lot of lives.

Yellowstone and Warming: An Iconic Park Faces Startling Changes – A few degrees makes a big difference….in National Parks too.

Scientists Find Toxic ‘Forever Chemicals’ in More Than 100 Popular Makeup Products – I hope manufacturers of makeup will check their ingredients more carefully….make their products PFAS-free.

Canada is right to classify single-use plastics as toxic – I hope the US takes similar action. Industry should get on board with this idea and be innovative rather than taking legal action.  There is no ‘responsible plastic use’ for single use plastic. We consumers are too accepting that single use plastics are inevitable. It’s pretty easy for us to avoid singe use plastic bags, straws, stirring sticks, six-pack rings, plasticware….the one that is challenging for me is the hard-to-recycle food containers because of the lack of options in grocery stores and restaurant takeout.

Move Over Bald Eagle: Meet 12 of the World’s Coolest National Birds – Some are flashy…some are majestic….a little history of how they were selected aa representatives for their country.

Losing Ladybugs – Native and non-native ladybugs….you are more likely to see the non-natives now.

Florida’s Manatees Are Dying at an Alarming Rate – Starving because water pollution (nutrient runoff causing algal blooms) smothers seagrass. More than 10% of the manatee population of Florida has died so far in 2021. Very sad for other aquatic species that need the same habitat … and people too.

Ten Little Celebrations – June 2021

After being away from home in May…being in Maryland again rippled with little celebrations associated with home. Here are my top 10 little celebrations from June 2021:

Scenic drive from Lexington KY to home. Light traffic, good highway, beautiful scenery….I took a picture to celebrate being back in Maryland.

Farmers Market. I’ve been going every week and it’s a celebration every time. The piles of produce fresh from the local farms (and artisan bread) make it a happy errand…and then I enjoy the bounty in meals all during the week. It’s a great substitute for belonging to a CSA (which is not practical for me this year because of my traveling).

A good watermelon. There was a sign in the produce section of Wegmans for seeded watermelons. I always remember them from my childhood….sweeter than the ones without seeds that we find more frequently in stores today. I bought one – hoping it would live up my expectations. And it did. Celebrating a watermelon as good as I remembered!

Yard work. An hour of work (several of them on mornings when it is still cool enough to be pleasant)…2 wheelbarrow loads to the brush pile or compost bin….celebrating a neater yard and satisfaction of encouraging native species.

Apple crisp. While I was away, my husband did curbside pickup for his groceries. He somehow got a huge bag of apples. Some of the excess apples made a great apple crisp…celebrating bounty (and not wasting food).

Howard County Conservancy Mt Pleasant. Every time I hike there, there is something new to celebrate – most recently dragonflies and a black-crowned night heron.

Maryland sunrise and partial solar eclipse. Celebrating being in the right place at the right time to see it.

New crowns. I had anticipated that getting 3 new crowns was going to be uncomfortable but was pleasantly surprised that my expectation was way over the top; there was almost no discomfort during the drilling or sensitive areas afterward…. celebrated that it happened that way.

New computer glasses. Hurray for seeing better…and the red frames.

The Institutions of Extraterrestrial Liberty talks. There were 4 days of webinars….and I found many of them very thought provoking. I celebrated the content…and that they were made available by the sponsors of the virtual conference. (Day 1: https://tinyurl.com/4t7zjv72 Day 2: https://tinyurl.com/2f9n4b72 Day 3: https://tinyurl.com/48rbba2k Day 4: https://tinyurl.com/5bbey7pr)

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.

Top 25 Birds of the week: Habitats! – Birds are everywhere (at least now/recent past). The decline in insect populations could make it problematic for many species to survive.

The Institutions of Extraterrestrial Liberty (Day 1: https://tinyurl.com/4t7zjv72 Day 2: https://tinyurl.com/2f9n4b72 Day 3: https://tinyurl.com/48rbba2k Day 4: https://tinyurl.com/5bbey7pr) – A series of webinars chaired by Charles Cockell (I enjoyed his astrobiology course on Coursera back in 2015 and his “Life in the Universe Pandemic Series’ back in Spring 2020). The subject in these webinars is freedom beyond Earth with talks on everything from liberty in Martian settlements to war in space. This is not about the search for life beyond Earth, but it is about the human future beyond Earth and how human societies might evolve over time. The schedule for each of the days is in the comments section so it is easy to select segments easily.

Gigantic flying pterosaurs had spoked vertebrae to support their 'ridiculously long' necks -- ScienceDaily – Their necks were longer than a giraffe’s…and the vertebrae had internal structure not seen in any other animal. The discovery was made with a CT scan and petrographic sections through the bone.  

Linking Birds, Farmer Attitudes and Conservation – The approach is not as straightforward as it might seem…there are nuances and feedback loops that need to be considered to get a positive result.

A breathtaking treasure reveals the power of the woman buried with it : Research Highlights – Early Bronze Age southeastern Spain…heavy silver diadem, silver ornaments…pots with intricate silver plating and daggers with silver-plated handles.

Challenging Conservation Not to Leave Women Behind – An example from the Solomon Islands….globally relevant.

100-Year-Old Lungs Yield Genetic Samples of 1918 Flu Viruses | The Scientist Magazine®- Lungs of 2 soldiers and a civilian preserved in formalin….from the first wave of the 1918 flu…when it was not as deadly as the later waves.

Why Peru is reviving a pre-Incan technology for water - BBC Future – One of the world’s first efforts to integrate nature into water management on a national scale.
