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.

Purple gallinule with chicks – I remember seeing an adult purple gallinule on a birding field trip in Florida. Aren’t the chicks cute? Little black fluffs.

Reproductive factors and dementia risk – Hurray! My life events skew toward reduced dementia risk…according to this study.

Macro photos reveal the often unseen beauty and diversity of slime molds – Hmmm…maybe I should hone my observational skills to find these on my next hike…attempt some macro photography of them.

As EV Sales Soar, Automakers Back Higher Fuel Standards – So glad that industry is finally onboard…projecting a ‘we can do it’ attitude. I’d rather society take action…build some optimism into our view about the future rather than being depressed by trends that seem dystopian.

Beginner’s Tips for Identifying Backyard Bird Nests – It’s the nesting time of year! Look…id…don’t disturb!

Ozone may be heating the plant more than we realize – We’ve been concerned about ozone in the upper atmosphere for years (hence the Montreal Protocol) but this study also points to ozone in the lower atmosphere (caused by chemical reactions between pollutants like vehicle exhaust fumes and other emissions) as contributing to climate change as well. Until now, we thought of lower atmosphere ozone as a health problem (I get headaches if I am outdoors on a high ozone day, for example). This research says that it also is contributing to climate change by affectioning ocean heat uptake.

American Lung Association Says EVs Save Lives – Good for our health….and also for the planet. I also noted that where I live now is in the American Lung Associations Tops 10 US urban areas at risk from airborne pollution…another reason to move away from this area!

New Technology Employed to Protect Pompeii – A four-legged robot used to gather data on structural and safety issues.

Flamingo that escaped from a zoo in Kansas is spotted once again in Texas 17 years later – The flamingo is a species from Tanzania….and must be a very lonely bird.

Brain charts for the human lifespan – Normative trajectories derived from over 100,000 MRI scans that allow quantification of individual variation. Figure 1 in the post can be enlarged by simply clicking on the image.

The Birds of California (Dawson/Brooks)

/

The Birds of California was published in 4 volumes in 1923. The author was William Leon Dawson with illustrations by Allan Brooks. There are some of Dawson’s photographs used as illustrations as well. Follow these links to see the eBooks: V1, V2, V3, V4. I selected a sample image from each book below.

Two aspects to keep in mind with a work of this vintage:

  • A lot has happened to California in the almost 100 years since the volumes were published. The habitat for some of the birds has probably succumbed to development or is degraded by pollution. Undoubtedly some of the birds are endangered…maybe a few are gone entirely.

  • Classification of birds is always changing. Some of these older books have birds as separate species that are now considered  single species. The advent of DNA analysis for classification is the most recent perturbation.

But these don’t detract at all from enjoying the illustrations!

Winners of Wildlife Photography Competition Show the Power of Water – Starting out the gleanings list with some eye candy this week.

Personality traits are associated with well-being and satisfaction in life after work – My husband and I have transitioned to ‘life after work’ and seem to have easily established ‘new fulfilling life patterns.’ In an odd way, the COVID-19 pandemic has helped us focus on the most important aspects of those patterns.

A New Study of the Permian Basin – a US oil-drippling hotspot is kicking out far more methane that we thought – I keep thinking that the technology to reduce emissions in the fossil fuel extraction process has improved from the early days. Maybe it has…maybe the hasn’t. The industry may not be motivates. Is it all about maximizing profits for them and their stockholders…everyone else doesn’t matter?

Toad Wisdom – A story of webs of life from the Prairie Ecologist.

European earthworms reduce insect populations in North American forest – Even small invasive species can have a significant impact.

Mapping Inequality – Redlining in New Deal America – An introduction….then downloads and data for maps for urban areas across the US from the 1930s.

Top 25 birds of the week: birds on flowers – Enjoy some photographs of birds…flowers…springtime!

Scents help researchers identify contents of Egyptian vessels – The smells of ancient Egypt!

Norway at new record high 92% plugin EV share in March – Hopefully the EV share in the US will start climbing more rapidly.

“Flash droughts” coming on faster, global study shows – Extreme weather….not all on the wet side.

Where Have All the (Big) Cypress Trees Gone ... And Are They Coming Back? – The cypress stands survived logging but they may never again be as dominant as they were before. The largest trees now are about 3.5 feet diameter; the largest stumps from logging are about 5 feet diameter.

8 bird migrations, from past to present – The annual movement of birds is a part of spring….part of the yearly progression.

Cherry Blossom Time In Washington, D.C. – I was glad to get home in time to see the cherry tree in our yard bloom; it’s a little behind the trees in DC (we are a little north and not on the water).

Nature Conservancy to build solar farms at abandoned coal mines in Virginia – And thus an energy producing community, continues…leaning into the future!

The sound of Merlin: like Shazam, but for birds – An app that IDs birds by their songs…a learning experience to take on a walk.

Higher risk of temperature-related death if global warming exceeds 2°C – We’ll have to be more aware of heatwaves. Perhaps we would modify our behavior during those times…and medical interventions might help. There is a heat threshold above which our bodies are not adapted very well…that will cause increasing problems.

Rarely Seen Paintings by J.R.R. Tolkien Portray a Lush ‘Lord of the Rings’ Landscape – Another perspective of Tolkien…through his art rather than writing.

No breathing easy for city dwellers: particulates – Southeast Asia has seen the largest annual average increases in concentration and mortality rates between 2000 and 2019 from this type of air pollution.

How climate change is leading to bigger hailstones – The records for the largest hailstones have been broken in the last 3 years in Texas, Colorado and Alabama….reaching sizes of up to 6.2 inches in diameter. Large hail causes a lot of damage…if the incidence of large hail increases the damage/costs will trend higher too; the post includes a picture of a car damaged by large hail…daunting to anyone that doesn’t have their car parked in a garage.

Missouri Man Indicted For Fire That Destroyed Ozark National Scenic Riverways Visitor Station – I am paying more attention to news about natural areas in Missouri…now that I am preparing to move to the state. It’s sad when this type of destruction occurs – hard to fathom why someone would burn a visitor station.

Zooming – March 2022

/

When I use my bridge camera, pictures are composed using the zoom on the camera. I chose 9 to feature in this post; they’ve already appeared in other posts with others from the same location, but I like to pull my favorites together as a way of summarizing the locations I enjoyed in March: home, Brookside Gardens, a yard in Carrollton TX and Josey Ranch Lake (Carrollton)…seasonal representatives of the usual types of subjects: plants, insects, birds.

How triple-pane windows stop energy (and money) from flying out the window – How long will it be before all window replacements and windows in new houses will be triple paned? I guess is depends a lot on affordability….and then availability. I like that they reduce noise too.

Yellowstone At 150: Challenges Go More Than Crowd-Deep – A post about Yellowstone’s past, present…projections for the future. My husband and I have only visited the park once…hopefully we’ll be able to see it again.

Beware the joro spider. Scientists say the giant, but harmless, arachnid is spreading – A native of Japan…it has been in the southeastern US for the past decade. It may be poised to continue up the eastern seaboard. Fortunately, they are not lethal to humans and the eat mosquitos/stink bugs.

Top 25 birds of the week: Seedeaters! – We see some of these at our birdfeeders!  

Cognitive Bias Codex, 2016 – A graphic I had not seen before….very thought provoking.

Revealing an Ice Age Route of Indigenous Peoples – Vancouver Island…analyzing lake sediments. One of them, Topknot Lake, was evidently never covered by glaciers so the sediment was very deep.

Hidden dangers lurking in your kitchen - A little history…and one that is relevant to my house hunting: I don’t want to buy a house with gas stove…if I do, it will be replaced with an electric ASAP.

Common house plants can improve air quality indoors – Modern homes are more airtight than ever…and indoor air quality can become a problem. Good to know that plants can help – and they are generally aesthetically pleasing too.

Spring is starting sooner and growing warmer – (A color coded map) Almost the whole US is experiencing earlier Spring. A small area of North and South Dakota is the exception.

Here are the world’s 25 most endangered cultural heritage sites – The post is a summary from Smithsonian Magazine. More details are available from the World Monuments Fund. There are sites in Ukraine that are in danger from the war there – will probably be on the next list (Smithsonian post and article with pictures of the 7 Ukranian UNESCO World Heritage Sites.

Bani Hasan Part IV from the Egypt Exploration Fund

/

Bani Hasan Part IV was published in 1893 by the Egypt Exploration Fund. It is a small volume (82 pages) available on Internet Archive as are some of the other volumes in the series…but this one was my favorite. It includes ancient Egyptian depictions of birds and animals as well as activities of daily life. I’ve selected 4 sample images from the volume.

I learned from the Wikipedia entry that:

  • Beni Hasan is an ancient Egyptian cemetery that spans the 21st and 17th centuries BCE…primarily the Middle Kingdom of ancient Egypt. The tombs are famous for the quality of their paintings.

  • Howard Carter (famous for discovering Tutankhamun’s tomb) spent a season there in 1891 as a teenager – producing watercolors of the tomb paintings. (He is listed on the title page of this book along with others.)

  • The paintings are now in poor condition.

Why soil is a surprisingly noisy place – Wow! A whole new way of studying soil…listening to it.

Gas flares tied to premature deaths – A study done by Rice University environmental engineers with data from North Dakota and Texas. There are currently no limits to flaring, unfortunately. Why can’t we use the gas productively? It bothers me when we hear that we need more fossil fuels to observe the way the industry still is so wasteful and polluting.

Dying for makeup: Lead cosmetics poisoned 18th century European socialites in search of whiter skin – I had heard of lead makeup before…but never is this detail.

Top 25 birds of the week: forest birds – The only one of these that appears in the forest behind our house in Maryland is the Tufted Titmouse.

Study questions the role of vitamin D2 in human health but its sibling, vitamin D3, could be important for fighting infections – The labelling on foods fortified with Vitamin D does not say which type is used – hopefully it is D3. The supplemental Vitamin D I take is definitely D3.

The Prairie Ecologist – Photos of the Week – February 26, 2022 – Winter photography….it’s about over for us. Daffodils are up!

What is the best age to learn to read? – There is more variability that I realized…generally between 4 and 7. There is growing consensus that there is no reason to rush it. Learning language is key and often older children learn to read faster because their spoken language skills are greater.

Effects of noise on marine life – The study was focused on turtles and observed noise-induced hearing loss (sometimes temporarily) which hampers their ability to detect predators, communication, navigation, etc.

Rash-causing moths are spreading in Maine because of climate change – Browntail moths (native to Europe). I thought when I saw the headline that it might be about the saddleback caterpillar which is native to North America and has stinging spines that cause a painful rash. We had a specimen in the Brookside Gardens Wings of Fancy exhibit back in July/August 2018.

Study of algae in Acadia National Park lakes shows recovery from acidification – A success story…the Clean Air Act Amendments enacted in the 1900s are making a difference!

After a shaky start, airborne wind energy is slowing taking off – Another way electricity might be generated in the future…but still a lot of work to be done.

Crews working to cull 600-900 bison from Yellowstone’s herds – I guess this happens every year at this time…even though in the rationale to cap the Yellowstone herd at 5,000 animals involved the mistaken idea that the bison were spreading brucellosis to cattle herds (research has shown that it is elk that spread the disease).

What damaged that tree? Probably not what you think – I guessed correctly….but only because I had seen something similar on a tree during a naturalist led hike…and they had identified the animal that make the marks!

The mystery of Mexico’s vanishing stream oaks – A great piece of trivia: Mexico has more species of oak tree than any other country! The article is about trying to save one of those species.

Three in four people worldwide support a ban on single-use plastic – Wide support…but no clear path on how we can do it. As a consumer – I try to avoid single use plastics, but some products don’t come in any other kind of packaging!

Seeing ‘green’ can ease confusion, anger in navigating hospitals – It’s not just hospitals that could use more natural views and ‘green.’

Top 25 birds of the week: waterbirds and seabirds – Terns, scoters, herons, gulls, cormorants, ducks, spoonbills, kingfishers, sandpipers, plovers, grebes…enjoy the photographs!

Warming temperatures are turning Antarctica green – Another indicator of how fast the Earth is changing….and that even Antarctica is not immune.

Drought depletes a reservoir in Spain, revealing a ghost village – The dam was installed in 1992 so this is not an old reservoir. The US is having similar drought related problems with Lake Mead behind Hoover Dam installed in 1935.

After 25 years at sea, shipwrecked Lego pieces are still washing ashore on beaches in England – Plastic is very durable…the pictures of the small Lego pieces still look pristine. Some of the pieces sank…some floated…they are all moving around and, very slowly, breaking down either in the ocean or on the beaches of Cornwall.

Daniel Giraud Elliot’s Bird eBooks

/

Daniel Giraud Elliot was a founder of the American Ornithologist Union and its 2nd President in 1890. I browsed through 7 of his well-illustrated books about birds from the later 1800s. Taxonomy has changed over the years, so they are not the ‘references’ they were when first published. But - they are historically interesting…part of the the uptick in documentation of the world’s flora and fauna in the 1800s. I looked at the illustrations as ‘art’ and wondered how many of the bird species depicted no longer exist. Enjoy the sample images…and take a look at some of the volumes via the provided links.

Oyster Hatcheries Help the Industry Adapt to Climate Change – There are lots of aspects of climate change that impact oysters – making mitigation more complex. The industry is trying to be proactive as problems are recognized.

Could COVID-19 still be affecting us in decades to come? – A summary of some research particularly about brain function/Parkinsons and diabetes relationship with COVID-19 just beginning…there is so much we don’t know yet.

The porcupine’s winter in slow-motion – How do porcupines in Alaska survive being out and about in the winter?

Top 25 birds of the week: Bird Interactions – Mostly adults of the same species…but there are a few with different species and the first image is a pair of young owls (siblings).

2,000-Year-Old Roman Bowl Discovered Intact in the Netherlands – Blue glass that look like it could have been made very recently.

Locations of ancient Maya sacred groves of cacao trees discovered – History of cacao (chocolate) trees…grown around sinkholes…so special that the beans were used a currency.

Monarch butterfly numbers soar in California after dramatic losses – It’s great to have some good news about Monarchs….but they’re still a species that needs our help.

AccuWeather shares how an electric school bus fares in Alaska – Evidently the bus has done well even at -48 degrees Fahrenheit!

Musings from the parks: Navigating National, Wild, Recreational, and Scenic Rivers – Prompted by a proposal to refine limits on the horsepower boaters can use in Ozark Scenic Riverways in Missouri…a look at regulations at other rivers in the National Park System. I’d prefer that we begin the transition to electric motors (if motors are allowed at all) rather than only focusing on horsepower.

Epidemiologists develop advanced state-of-the-art tool for measuring the pace of aging – A blood test to measure the pace of biological aging…with the possibility of identifying interventions that would slow aging… and attempt to build aging health equity.

Birds through my Office Window - January 2022

/

There seemed to be a lot of bird activity visible from my office window this past month. The most common ones – juncos, sparrows (white-throated and house), finches (gold and house) - do not feature as much in my photos but they were always around.

Mourning Doves are too heavy for the feeder, but they are frequent visitors under the feeder on the deck and out in the yard. They also perch in the maple. They look largest when it is cold, and their feathers are fluffed.

The Northern Cardinals come to the feeders and flit all over the yard and trees. They seemed to be more activity in January than usual because there were more of them around. We have a resident pair that are around all year but in January there were at least 2 other pairs that were occasionally coming for food…and the interactions of both the males and females were high drama to watch.

The other resident pair that we usually see all during the year are a male and female (pictured) Red-bellied Woodpecker. Hopefully they’ll have young again this year. The birds dig through the seeds at the feeder…always leave with a peanut or sunflower seed.

There was a hawk that was around occasionally. Once it was at the edge of the forest diving into the leaves…came up empty. Another time I heard a tussle on the deck and glanced out to find the hawk on the deck railing – also without prey that it had probably been stalking. I was particularly relieved that it didn’t kill one of the birds coming to the feeder!

I’ve noticed Northern Flickers more in our yard. They blend into the leaves so well they are hard to spot…don’t come to the feeders.

The White-breasted Nuthatch comes to the feeder and is very assertive – drives away all except the Red-bellied Woodpecker.

There was a mixed flock of Red-winged Blackbirds and Brown-headed Cowbirds (pictured) that flew into the treetops of at the edge of the forest. I was glad they didn’t come down to our feeders! There were occasionally some cowbirds that came in the subsequent days; hope they don’t stick around for nesting season.

The downy woodpecker doesn’t come to our feeders frequently; they must be very hungry when the do because they eat quite a few seeds!

Photography In the National Parks: My 10 Favorite Shots From 2021 – I only went to one national park in 2021: New River Gorge (in West Virginia). There are so many beautiful National Parks to see…and they’re worth seeing again and again.

Big Gulp: Blue Catfish Eat Wood Duck – We’ve seen fishermen catch blue catfish at the base of Conowingo Dam (we’re there for the bald eagles). They are huge…sorry to learn that they eat ducks.

Top 25 birds of the week: Raptors! – How many of these live in your area of the world?

Air Pollution Makes It Harder for Bees to Sniff Out Flowers – Not just a problem for bees…also moths, hoverflies and butterflies are having a harder time. This results in a 14-31% reduction in pollination among plants exposed to polluted air.

Ocean microplastic pollution may be greater than estimated – Not a good trend…and this form of pollution that is new enough that the full impact is still being discovered.

With Fewer Animals to Move Their Seeds, Plants Are Stuck in Threatened Habitats – Another way the world is becoming less resilient at a time when climate change is pushing all life to use all the resilience available.

Large Permian Basin Methane Leaks Are Causing As Much Climate Pollution as 500,000 Cars – It’s frustrating that the oil industry has not been a better steward of resources they are extracting for energy. The methane leaks are a waste of the effort put into extraction….and bad for the planet too.

Dinosaur food and Hiroshima bomb survivors: maidenhair trees are ‘living fossils’ and your new favorite plant – Learn more about the ginkgo tree! There is one along my walking route in my neighborhood and others I find in local gardens and parks near where I live. They are so different from other trees…worth noticing.

North Sea Fossil Fuel Companies Plan to Invest More in Wind than Oil Drilling – Hurray! Maybe other companies around the world begin to do this too….a strategic move for Shell, Total and BP.

Antimicrobial resistance now a leading cause of death worldwide, study finds – This challenge will increase over time…if we don’t take action to slow the development of resistance and develop new antimicrobial techniques (maybe we need more strategies than simply trying to develop new antibiotics).

The Roots of Violence – Reexamining bones excavated in the 1960s with new 3D imaging techniques….defining the violence of their lives and deaths shown in the bones. There is a history of archeological thinking here too. For a long time, evidently there was a presumption that prehistory was a less violent time…but the evidence is mounting that it was not.

Reducing air pollution: policies that pay off – An analysis done in Europe of the economic benefit of measures to reduce fine particle air pollution from wood heating and transport. It seems that similar type analysis could happen in other places in the world with some variation to tailor the reductions to have the biggest impact.

30 Incredible Winning Photos From the 2021 Nature Photographer of the Year Contest – Some eye-candy. My favorite is the caterpillar ‘walking among fennels’ – a similar scene happened at our CSA the first summer of the pandemic.

Assessing the U.S. Climate in 2021 – There were 20 separate billion-dollar weather and climate disasters that impacted the US in 2021.

Savanna Fire Management Can Fund Africa’s Protected Areas – Another article about the new economics we will need to understand to address climate change.

The forgotten medieval habit of 'two sleeps' – Maybe one long period of sleep is ‘modern’….that humans slept in two phases prior to the industrial revolution. One of my grandmothers developed a ‘two sleeps’ pattern late in her life when she was living alone….and I am beginning to wonder if I will.

The Horned Helmets Falsely Attributed to Vikings Are Actually Nearly 3,000 Years Old – Another look at artifacts…and better dating…and the history derived/assumed previously is changed.

Top 25 birds of the week: bird coloration! – This time of year…a little color from birds is a welcome sight. I’m noticing the ones in my neighborhood: Northern Cardinal, House finches, and red-bellied woodpeckers.

Across the Boreal Forest, Scientists Are Tracking Warming’s Toll – The northern forests becoming carbon emitters….. peatlands are drying out, and hotter, drier conditions are leading to a steady increase in wildfires — all of it accelerating permafrost thaw.

The Legacy Of "Pele's Grandson," Alex Lancaster – Some history of volcano observation on the big island.

Top 25 Birds of the Week: January 2022 – This set includes a photo of a white-throated sparrow…one of the birds we see at our feeders only in the winter (along with juncos).

Threatened and Endangered Parks: Ghost Forests and rising seas – I recognized Blackwater National Wildlife Refuge in the pictures; I’ve visited it more frequently that any other NWR…and have observed some changes over the years. It was the first place I saw a bald eagle in the wild…back in 1990.

Musfur sinkhole: The chasm in Qatar’s desert. – Usually we think of the Arabian Peninsula being full of sand…but there are evidently sinkholes as well…deep enough to show layers of limestone and gypsum.

The Western megadrought is revealing America’s ‘lost national park’ – The water level in Lake Powell has fallen so much that Glen Canyon is revealed again. Gorgeous.

California mice eat Monarch butterflies – Mice eating butterflies that are on the ground had been observed in Mexico’s aggregation site…and now a similar interaction has been observed at a site in California where the Monarch’s aggregate.

Race and ethnicity across the nation – Data from the most recent census visualized on a map. Explore some places you know.

Findings open the way to more precise diagnoses and treatments of Alzheimer’s disease – A difference in Tau protein relates to slow or rapid development of the disease. There is a lot of research on the Alzheimer’s and other diseases that cause cognitive decline going on; with aging populations around globe, it is important to refine the way the diseases are diagnosed…and then treated. One treatment is not going to work for all.

Here's what you should keep in your car and other ways to prepare for winter driving – After the recent prolonged closure of I-95 in Virginia, I started thinking more about this…and will pack a few extra things in my car if I make a road trip to Texas this winter. I would normally have the items listed in the article anyway since I am minimizing the need to stop along the way during the pandemic (but I would need to check the batteries in the flashlight…and add some extras). I would add a sleeping bag too since it is relatively compact and would make it a lot easier to stay warm; I was surprised that this item was not on the list in the article. And I will not wait until the gas tank is down below ¼ tank before I stop for more!

See something weird at the bird feeder? It’s not just you – So far, the only somewhat unusual bird I’ve seen at our feeder was a red-breasted nuthatch; we see the white-breasted ones all the time but there was a season that we had a few of the red-breasted birds too.

See Pandas, Elephants, Cheetahs and More Enjoy a Snow Day at the National Zoo – Fun in the snow…the young panda seems to enjoy rolling or sliding down hills!

2021 Year In Review: Top Stories From The National Parks – Lots of perspectives in these ‘top stories’ – lots of challenges but some room for hope in 2022.

Earth in 2021 – A 3-minute video summary from NASA….lots of before and after catastrophic events. The text in the post has a short description of the events in the video.

Top 25 birds of the week: Birding! – Bird photographs…always a great look.

Stopping dementia at the nose with combination of rifampicin and resveratrol – The research was done in mice…they started preparation for human clinical trials in November. If it is effective in humans and can be produced/distributed economically, it could be a boon for aging populations around the world.

Saguaro National Park – A place I visited frequently while by daughter was in Tucson for graduate school. It’s interesting how they are monitoring the keystone species in the park…concern is that fewer young saguaros are surviving these days.

Climate-driven weather disasters inflicted billions in damage in 2021, study says – The cost of climate change already is impacting economies around the world….doing something to reduce/mitigate climate change is quickly becoming the option that makes the most economic sense for everyone.

Poison Ivy – You don’t want to touch it…but it’s best left alone when it’s growing in a place where people are unlikely to contact it. Its berries provide food for birds in the winter, it does not hurt the trees it climbs, and its leaves turn red in the fall.

Chalk steams: why ‘England’s rainforests’ are so rare and precious – This article brought back memories of wading in chalk bottomed creeks in the Dallas, TX area when I was teenager. I don’t remember much about the plants and animals…more about the fossils weathering out of the chalk.

2021 Year In Review - Another Year of Photography During The Pandemic – Beautiful places…and some little photography lessons too.

The year in chemistry: 2021’s biggest chemistry stories – 2021 was quite a year for big chemistry stories! Several of them are likely to have high impact for years to come.

Philip Henry Gosse Books

/

Back in October, I enjoyed browsing 8 volumes published in the mid-1800s by Philip Henry Gosse available on Internet Archive. He was an active naturalist and popularizer of natural science with his ability to create appealing/accurate scientific illustrations for his books. I found out from Wikipedia’s biography of him that he was the inventor of the saltwater aquarium in early Victorian England too. Enjoy browsing a Gosse book or two or three…

New copper surface eliminates bacteria in just two minutes – One of the emerging technologies to fight bacteria (and viruses) without antibiotics. Copper is already being used in some applications, but this materials research developed a new structure of copper that is more effective and faster. The article didn’t comment about durability…but still very promising finding.

Home Battery Storage: The (Solar) Rich Get Richer – There is beginning to be more equity in solar panel installation….but storage is still a challenge at lower incomes. Some states have programs that may be the wave of the future and there are incentives in pending legislation. Hopefully a positive momentum will build over the next few years.

California Readies Launch of Largest Food Waste Recycling Program in the U.S. – Part of the county where I live in Maryland has curbside pickup of food waste for composting…but not the part where I live. I have a backyard compost bin…but many people do not so there is still considerable food waste going to the landfill.

10 Winter Birds to Spot During the Christmas Bird Count – Seen any of these in your area?

Why is snow white? – 3 videos…the last one with more ‘bonus’ explanations (such as why polar bears are white).

Top 25 birds of the week: Bird Pigment – This post was a bit confusing since it wasn’t explicit about which colors were from pigments ( as in the red of cardinals) and which were from light scattering caused by the physical structure of the feathers (for example, in blue jays). Read more about this non-pigment phenomenon particular for blue feathers here.

Winter is coming: Researchers uncover the surprising cause of the little ice age – New research shows that the little ice age in the early 1400s occurred when the Atlantic Meridional Overturning Circulation (AMOC) collapsed after a warming period which flushed Arctic ice into the north Atlantic, cooling it and reducing its saltiness. Could the AMOC collapse again with ice melting because of climate change? Existing climate models do not model the impacts of ice melt (making the north Atlantic cooler and less salty)!

From blood clots to infected neurons, how COVID threatens the brain – An overview of the research into how COVID-19 impacts the brain; there is still a lot more to be learned about this - probably one of the most devastating aspects of ‘long Covid’. It appears that the cognitive impact experienced by some COVID-19 survivors improves over time, but half the patients in one study were not back to normal after a year. It is a very sad prospect for individuals and for or society.

Watch This Giant Phantom Jellyfish With 33-Foot-Long Arms Float Through the Deep Ocean – The video is less than a minute…worth watching.

AAA Electric Vehicle Infographic — The Good & The Bad – My current car is a plug-in hybrid….the next one will most likely be an EV.

It was a challenge to pick one picture from each month of 2021 to feature in this post….but a worthwhile exercise. I did not use consistent criteria for my choices, so these images are special for a variety of reasons.

January for witnessing interesting bird behavior – A bluebird on our deck railing looking up at our bird feeder full of other members of the flock…waiting a turn!

February for learning to make high key images – A high key image of a lily….the flower purchased at the grocery store. I had just watched a video about high key photography and was thrilled to have some easy successes.

March for beauty old and new – The crocus were out at Brookside Gardens but I found the remnants of last seasons flowers more interesting.

April for a bird trusting that I wasn’t a threat– A bird looking rather assertive. I had paused its search for food in the leaves to make sure I wasn’t a threat; evidently I wasn’t because it went back to its search a few seconds later.

May for memorializing a bird – A juvenile little blue heron in the cattail leaves at Josey Ranch in Carrollton TX. It had a broken wing so I think of this image as a monument to its short life.

June for something that only happens every 17 years – The periodic cicadas seemed to be thick everywhere – even our yard. This one was under our red maple.

July for interconnection in nature– Back in Texas…am insect on a cosmos flower on a cool morning.

August for the fragile beauty of a new butterfly – A monarch butterfly seconds after it emerged from its chrysalis is our front flower bed.

September for capturing a small thing, seeing it better than I could with my eyes – Some birds nest fungus in the mulch at Howard County Conservancy. I was thrilled that I had my gear (phone, clip on macro, clicker) even though I hadn’t planned to do any macro photography!

October for being in a river – More macro photography – this time the wing of an insect on a rock just above the water line….photographed on a volunteer gig before the students arrive.

November for the colors of the flower – Another view of a cosmos flower. I like it when the light is such that a black background is possible.

December the new orb sculpture at Brookside – A surprise (for me) at Brookside – I hadn’t seen this sculpture before…and I also enjoyed the holiday lights (missed them last year).

Gleanings of the Week Ending December 18, 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.

Monkeying Around with Venom – Hadn’t heard about ‘Snake Detection Theory’ before; it is the idea that snakes have exerted a selection pressure on the origin of primates’ visual systems, a trait that sets primates apart from other mammals. This paper is some recent research that supports the theory.  A condensed description of the research paper is found here.

Why climate lawsuits are surging - Lawsuits are becoming tool to force change…in conjunction with activism, policy and science. There have been some successful lawsuits…and more in the pipeline. Sometimes the suit is about better enforcement of environmental laws…and sometimes it is about climate protection for future generations becoming a constitutional issue.

Florida to Feed Starving Manatees, as Pollution Shrinks Food Supplies – Florida farm runoff caused alga blooms that cut the penetration of sunlight into the water so much that it killed the seagrass that manatees eat…and there have already been more than 1,000 that have starved. It is estimated that there are about 8,000 manatees remaining in Florida waters. It is unclear that the seagrass can be restored.

Top 25 birds of the week: December 2021 – Enjoying bird photographs!

How volcanic eruptions helped the ancestral Puebloan culture flourish – Response of people to the stresses of abrupt climate change evidently resulted in larger population centers…universal pottery making and turkey cultivation…more sedentary living…increasing social inequity.

Major Contract Awarded To Rehabilitate Section Of George Washington Memorial Parkway – The parkway is along the Potomac River between Great Falls and Mount Vernon. It was one of the first beautiful and history things we discovered when we moved to the area in 1983…and long overdo for renovation. Parts of it carry a lot of daily commuter traffic in Northern Virginia.

The impact of drugs on gut microbes is greater than we thought – Most people are aware of the impact of antibiotics, but other drugs impact the gut microbes too…and some of those drugs are treating chronic conditions so are taken for years. It appears this study was mostly about methodology to tease out the impact of drugs vs the underlying disease….much more work still to be done before concrete recommendations can be made.

The race to make vaccines for a dangerous respiratory virus – RSV (Respiratory Syncytial Virus). There are currently 4 candidate vaccines and one monoclonal antibody treatment that are in last-stage trials. It appears we are at the cusp of much faster vaccine development times because of what happened to develop the COVID-19 vaccines.

The tomatoes at the forefront of a food revolution – The idea is to use Crispr modification to sustain the productivity of the tomato crop as the climate changes.

Chronic exposure to air pollution may increase risks for ICU admission or death among COVID-19 patients, study finds – Sometimes it is hard to separate the role of the environment on health disparities. This study analyzed 6,500 COVID-19 patients admitted to 7 New York City hospitals.
