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.

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.

30 years ago – August 1991

/

August 1991 was a stressful month at work for me – several people I depended on took advantage of an early retirement offering from the company and the two projects I was working on were both demanding a lot of time. It might have been one of the highest overtime months of my career after motherhood. Between work and my daughter’s needs, I had very little discretionary time for myself. It was the month I fully appreciated how critical my husband’s support was to enable the peaks of my career.

We had a surprise visit from one of my aunts (with her husband and 2 grandchildren); they only stayed one night but it just added to the overwhelming activity for the month.

We had visited Texas in July and were getting follow up letters in August: my Mother starting her last year of teaching, one sister house hunting and planning to visit in October, another going through similar motherhood experiences with her child the same age as mine, and the sister 8 years younger than me realizing she didn’t know me very well. The documentation I have for the month is largely through those snail mail letters!

My daughter was savoring some activities at home that she had enjoyed for the first time while we were in Texas: dabs of shaving cream to wear around before playing in her pool (a substitute bath) and painting (on paper and herself). She was beginning to use her right hand more although she was not as strongly right-handed as her cousin. She discovered she could make footprints on the deck if she walked with wet feet.

She also remembered music from the Texas visit. Whenever the cassette tape with “Let’s go fly a kite” on it played…she always smiled and clapped when that song played.  

When we went to Wheaton Park we discovered she liked the swings under a large catalpa tree better than the carousel!

It was a time of tension between work and motherhood. The techniques I had for coping were developing - not perfect; over the next few years – I accepted that it was OK to always be developing rather that achieving perfection. But in August 1991, I was pushing for perfection.

I also noted a high ozone day. Looking back, I realize that if there had been action during the 1990s…the climate situation would be better today. I was aware of the greenhouse effect…and that the earth was warming; but in 1991 I thought it was an academic idea, not something that was actionable. Like so many others – I thought it would be very gradual and there would plenty of time for corrective action. So now we are facing an urgent need to pivot --- a challenge to us all. I find myself thinking about what it will be like in 30 years – trying to take actions in my own life to sustain hope for the successful transitions we’ll have to make going forward.

Emerging Monarch

/

I went out each morning after finding the Monarch butterfly chrysalis on the day lily leaf; on the second morning that the chrysalis had turned from pale green to clear – the indication that the butterfly was almost ready to emerge. Since I hadn’t seen any Monarchs in our yard this year…I decided to attempt capture the emerging butterfly with my camera.

I came back 30 minutes later…thought perhaps the chrysalis wall was weakening…that some parts in the middle were beginning to split. I had changed to my bridge camera (Canon Powershot SX70 HS), mounted it on a monopod, and was sitting on a comfortable stool.

30 minutes later it looked like the top – above the horizontal row of gold dots - was beginning to split.

Another 30 minutes and I was out again – zooming in with the camera and thinking, at first, that nothing much had changed. But then I noticed some action on the other side of the chrysalis.

I changed to video since I knew the emergence would happen very quickly. It is not a great video (I need practice with video as much as I do with macro photography!) but I learned a lot from watching it later. The chrysalis did crack open but not exactly in the way I anticipated. What I was seeing at the top of the chrysalis was the abdomen of the insect which was huge! It must contain the fluid that is needed to expand the wings. The papillae on either side of the proboscis moved a lot at the beginning and I wondered if they were somehow involved in the fluid distribution or simply cleaning up the area around the face. See the video here.

After the video of the main event – I went in to let my husband know it had occurred and came back out to finish the event with some photes. Over the next 30 minutes the butterfly’s wings continued to unfurl and expand. At some point the butterfly ejected the extra fluid in its abdomen.

30 minutes later the butterfly finally opened its wings. Note that the abdomen is smaller than when it first emerged and it is probably a female.

What a great way to start the day!

Day Lily Leaves

/

In the later part of summer, I always cut the day lily leaves when they start to turn yellow so that they come back with new growth that is fresh and green until the frost. It probably reduces the amount of bulb growth underground but the beds are so dense in the beds that it doesn’t matter. Last year it happened in early August. This year the leaves stayed green longer. Maybe we got more rain or maybe the temperatures were better for the leaves to continue growing – or maybe their season is longer now due to climate change. The two areas we have day lilies are in the front flower beds and around the base of our oak tree.

20210821_072558.jpg

And every year, one of the tools I use is the old hedge trimmers I have from my grandfather.

He gave them to me when I bought my first house in the mid ‘70s; the handles were already mended. They must be over 50 years old and maybe much older! They are a wonderful reminder of him. I like using them more than the electric hedge trimmers because of the good memories that crowd into my mind when I pick them up (and they don’t bother my hands as much as the vibrations from the electric trimmers do). I also think how much things have changed since he was born in 1901…the way we now live on the Earth with a lot more people and technology that is damaging the planet…how we have to make some difficult changes to enable ourselves and future generations the quality of life on Earth that recent past generations experienced.

The area around the base of the oak was trimmed all the way around. When the new leaves come in they will cover over the mess. I noticed one side was lower than the other and realized the deer must have been nibbling there. The bed near the house was another story. I got about half done – avoiding cutting any of the black eyed susans – when I stopped because of a small discovery.

Do you see the Monarch chrysalis on the leaf (near the center of the image)? I was surprised to see it since I hadn’t seen any Monarch butterflies or caterpillars this year in our neighborhood. I’m going to take a daily picture of it until the butterfly emerges.

20210821_081701.jpg

Tomorrow’s post will include a few macro pictures of the chrysalis so stay tuned!

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.

Henriette Willebeek LeMair

/

This week I am highlighting 4 Internet Archive books published between 1912 and 1917 that include Henriette Willebeek LeMair’s illustrations of children. They are an idealized version of childhood during that time in Holland. I was interested in the activities depicted!

Grannie’s Little Rhyme Book (1914) is a collection of old nursery rhymes that she illustrated.

The Children’s Corner (1915) was written by R.H. Elkin. Ordinary things like a child getting a haircut and dolls in timeout show up in the text and illustrations!

Old Dutch Nursery Rhymes (1917) has tunes compiled by J. Joentgen…with the English added by R.H. Elkins. The illustrations I chose for my samples are for tunes “The Ducks” and “The stork has brough a baby brother”!

Little Songs of Long Ago (1912) has tunes compiled by Alfred Moffat. The tunes illustrated by the samples below are “Dame get up and bake your pies” and “See-saw, Marjorie Daw.”

Life has changed in many ways for children in the past 100+ years….but the spirit of children that comes through in the illustration is still easy to find today. What will it be like for children 100 years from now? It is something I am thinking about a lot recently….and how I can turn my concern about the changes happening in the Earth’s climate into action.

Precursors to Fall

/

It is not fall yet but we already have a few leaves falling; the majority are oak or sycamore. There are always the precursors to the big fall that happens in a few months…usually reaching a crescendo in October in our part of Maryland.

s 2021 08 IMG_5006 (4).jpg

There is always one corner of our deck where the leaves accumulate. The wind sweeps them into the corner and the only way they leave is with some effort on our part with a broom or rake. Right now - they are mostly sycamore leaves but later the tulip poplar leaves will be there too.

The sycamore leaves are sometimes bigger than dinner plates this time of year. The big ones have been growing all summer. There are still smaller, younger ones on the tree….and sometimes they fall off while they are still green. I noticed an odd leaf that was very dark around the edges…not the normal look to a sycamore leaf on the ground and I’m not sure what caused it.

The oak leaves are changing color on the tree – looking glorious in morning light.

There are some unusual looks for the oak leaves too – green at the stem area then brown in the upper part of the leaf or green in the center and brown around the edges. These leaves might indicate the tree is somehow challenged – hopefully something it will recover from.

I am trying to separate what is normal for our trees and what I might notice that is an indication of climate change. One thing I am starting to monitor is when the big last big swirl of leaves happens from the tulip poplar; in fall of 1994 (the year we moved into this house), it occurred on Halloween. I wonder when it will be this year.

Black Squirrel

/

We have a black squirrel visiting our deck occasionally. The zoomed images show that the undercoat fur in not black and the claws are more visible because of the contrast with the coat color. Other than the darker coat, it seems the same as the other squirrels; it doesn’t get seed directly from the feeder either. I’m pretty sure it is in our neighborhood all the time…that our deck/feeder/bird bath are on the edge of its normal territory so we don’t see it every day.

The acorns are not having a big year – so the squirrels may be keener to get the seeds this year. The last few years have been slim for acorns from our oak. I’m not sure if it’s just the normal fluctuation between mast (big acorn) years, if our oak is infected with something that reduces its acorn production, or if the weather in the spring caused a problem. I am pretty sure it was some cold weather in the spring of 2020 but not sure about this year.

Our oak (and the others in our neighborhood) are more important to the long-term health of the squirrels (and other wildlife in our neighborhood – including birds and insects) than our feeder. In an ecosystem being challenged more and more by climate change – we are becoming more aware of how our actions are important to sustaining what is here.

Changing Food Habits

/

It’s hard to change the foods we eat. Recently several articles about ultraprocessed food and the impact of our food choices on the environment have prompted me to evaluate what it eat…and decide on some changes I want to make. It’s going to be hard…many of the foods I am focused on are well-entrenched habits. This is only the beginning.

20210814_081914.jpg

Diet Pepsi (and other soft drinks). They are not food – just liquid that has 0 nutritional value and may have negative impacts on health (jitters and hydration skew caused by caffeine, increasing craving for sugar). But I’ve been buying and drinking them for a very long time; they are a habit that is hard to change. Earlier this year, I changed from plastic bottles to aluminum cans when it became obvious that plastic bottles were not being recycled properly (whereas aluminum cans were)…but that is not enough. When scrutinized objectively – they are not worth anything positive…so why buy them at all.

Peppermint candy. Aargh! These come in big bins…I buy them when I travel then continue eating them after I get home. The lure of sugar and peppermint. I will stop buying them to avoid the temptation. Maybe I should start chewing fresh mint leaves from the garden to get the flavor but not the refined sugar!

Soy or Almond Milk. I’ve been drinking the non-dairy milk – to get calcium via my diet without the challenge of lactose intolerance. The change I am contemplating now is to transition to lactose free milk as a less processed alternative and get more protein too (9 grams vs 6 grams for soy milk).  Also - all the non-dairy milks have supplemental calcium so they are almost like taking the supplement which is an ultimate in ultraprocessed ‘nutrition’!

Turkey sausage. Highly processed but a better choice than pork sausage in terms of calories from fat and also less environmental impact (poultry vs swine). It does have a lot of sodium. I won’t eat it more than once a week or so…but is a quick way to add protein to a meal.

20210814_081748.jpg

Dark chocolate. Ultraprocessed…but I am choosing to still have it for my 1st breakfast (two squares of the Lindt 70% is my favorite). I like the kickstart it gives my day…enough calories to keep me going before I am ready to prepare my 2nd breakfast at mid-morning. But I am not going to eat more than that small amount very often.

Overall – I am pleased that I have so many fresh vegetables (and some fruits) in my diet. I enjoy the farmers market and the produce section….and finding new ways to prepare salads, smoothies, soups, stir fries – skewing toward raw and whole!  I haven’t become a vegetarian – yet – but I am eating less meat that I was 5 years ago (almost no pork and less beef)…ramping up nuts.

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).

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!

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.

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:

20210602_114618.jpg

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

20210620_095023.jpg

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!

20210604_073259.jpg

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.

2021-06-10-Sunrise partial solar eclipse-6071.jpg

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)

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. Projects include protecting high altitude cushion bogs and shoring up ancient water storage (routing water in the wet season to natural infiltration basins). These are ‘slow water’ solutions…mitigations that should be studied for other areas that are drying out as the climate changes.

An Estimated 50 Billion Birds Populate Earth, but Four Species Reign Supreme | Smart News | Smithsonian Magazine – And the 4 species are: house sparrow, European starling, ring-billed gull, and barn swallow.

How humanity has changed the food it eats - BBC Future – Perspectives on the processing of food through our history (and pre-history)…and where we are now. It is still possible to make choices that are healthy for us…but a lot of ultra-processed ‘foods’ readily available that are not.
