Pair of Resting Cuckoo Bees Wins the Royal Entomological Society’s Insect Photo Competition – Wonderful images of insects. My favorite is the Wavy-lined Emerald Moth (“A forest gem”).

The Role of Commons in Our Future Resilience - The climate and biodiversity crises will make collective land and water resources the source of future cooperation and conflict. If our commons aren’t governed well, we can have a “future of global violence.” Balancing the needs of local communities and conservation and restoration will require strong relationships between governments and the people who depend on commons for their livelihoods and culture.

Study shows how liver damage from stress and aging might be reversible – The study showed that aging exacerbates non-alcoholic liver disease by creating ferroptic stress, and by reducing this impact, we can reverse the damage.

Extreme Heat’s Far-Reaching Impacts - In addition to the expected impacts — dehydration, heat exhaustion, and heat stroke — heat can also endanger pregnant women, impact sleep patterns, and increase irritability, depression, and suicide rates. Heat is also associated with higher rates of violence and aggression, including intimate partner violence and gun violence.

The chemistry of Polaroid photography – The technology behind taking a picture and printing it instantly.

Cooling Solutions for Cities That Lower Surface & Air Temperatures – Some productive and appealing ways to cool urban heat centers.

Funny Early Entries of the 2024 Comedy Wildlife Photo Awards – Images that will make you smile!

Climate change and sea level rise pose an acute challenge for cities with combined sewer systems - Some 40 million people currently live in areas served by combined sewer systems (in places like Philadelphia, New York, and Boston) that are at increasing risk of being inundated by untreated sewage during floods.

Ancient Egyptian Scribes Were Worked to the Bone - Scribes sat in cross-legged or kneeling positions for long periods of time, hunched over paper and ink. Such activity was bound to overload the jaw, neck and shoulder regions. 30 skeletons of scribes from a northern Egyptian cemetery were examined. Much of the damage was found on the skeleton’s right sides, with the right knee being an especially common point of osteoarthritis, possibly because scribes repeatedly squatted on their right legs, the researchers theorize. And ancient Egyptian iconography commonly depicts scribes writing with their right hands. The posture impacted scribes’ backs.

Pronghorn Place: Preserve Protects Wildlife Migration Route – About the Flat Ranch Preserve on the outskirts of Yellowstone National Park…what has been learned about the Pronghorns migrating through. It reminded me of the pronghorns I saw at Sevilleta National Wildlife Refuge (New Mexico) in 2018.

Northern Pacific Railroad eBooks from 1880s

/

The eBooks of the week are from a railroad company in the 1880s…illustrating some of its routes. They provide a view of some special places of the time – when the west was still somewhat ‘wild’ but developing rapidly with the extension of railroads and more people coming. Enjoying browsing these books on Internet Archive!

The Wonderland route to the Pacific coast (1885)

 I think about where my ancestors were at the time these books were published. One side of the family was still in Bohemia (Europe) – not emigrating to the US until a decade later. The other side was already in the US and mostly in Missouri.

Two Baby Condors at Pinnacles National Park Are Healthy, ‘Adorable Fluffballs’ – Avian flu killed at least 20 California Condors in Arizona and Utah last spring…so the health of these birds is great news. So far, their lead levels (often a problem if their parents bring them carrion with bullet fragments) are low. They will make their first flights in October or November.

Biden Designates Baaj Nwaavjo I'tah Kukveni - Ancestral Footprints of the Grand Canyon National Monument – Protecting the land around Grand Canyon National Park.

Nearly Two-Thirds of All Species Live in the Ground, Scientists Estimate - Soils are richer in life than coral reefs or rainforest canopies, providing a home to nearly two-thirds of all species. The study is the first to tally the total number of soil dwellers, large and small, finding that more than twice as many species live in the ground as was previously thought: 59 percent of all species depend on soil for their survival, including 90 percent of fungi, 86 percent of plants, and 40 percent of bacteria.

Incredible Winners of Light Microscopy Awards Show Artistry of Scientific Imaging – The beauty of microscopic life….

Research Sheds Light on Steamboat Geyser’s Eruptions, Past and Present – They discovered that the strength of shaking decreased as snow depth increased. The ability of snow to absorb sound makes a difference!

Stunning Fields of Sunflowers Are Blanketing North Dakota – The states farmers grew 625,000 acres of sunflowers this year…and they bloom throughout August. Maybe one year we’ll make the trek to see them; I haven’t been to North Dakota before.

Exceptional Winners of the 2023 Nature inFocus Photography Awards – Beautiful…and educational. My favorite image is the ant with aphids (“A Sappy Alliance”).

What Pots Say—and Don’t Say—About People – “What can such a well-traveled artifact tell us about the people who left it in the ground? Its culture of origin may be less important than how it fit into life where it was found.”

Microplastics found in human heart tissues, both before and after surgical procedures - Everywhere scientists look for microplastics, they've found them -- food, water, air and some parts of the human body….even in the heart. But it still is not known how/if the microplastics impact the cardiovascular system.

Microalgae vs. Mercury - In the search for ways to fight methylmercury in global waterways, scientists at Oak Ridge National Laboratory discovered that some forms of phytoplankton are good at degrading the potent neurotoxin.

Four key questions on the new wave of anti-obesity drugs – Several of the drugs were originally developed to treat type 2 diabetes but now are popular weight loss drugs.

Sweet smell of success: Simple fragrance method produces major memory boost – A study done by the University of California, Irvine on older adults…participants reaped a 226% increase in cognitive capacity compared to the control group. A product based on their study and designed for people to use at home is expected to come onto the market this fall.

How the US is fighting back against deadly floods – Identifying flood plains…not building back in them after a flood.

Old-Growth Trees, Some Dating To 17th Century, Protected at New River Gorge – The Burnwood Loop – where I want to hike first in the New River Gorge National Park and Preserve!

Does Cooking with Gas Stoves Hurt Indoor Air Quality? – Yes…but how much is the better question. 12.7% of current childhood asthma in the United States is attributable to gas stove use.

A quick look inside a human being – Magnetic Particle Imaging (MPI)…using a portable scanner to visualize dynamic processes in the human body such a blood flow.

Why it's so important to figure out when a vital Atlantic Ocean current might collapse - Humans are changing the fundamental processes of the Earth faster than we can understand them. The collapse of the current would have effects around the planet: temperatures in Europe would fall, heat in the tropics would rise, rainfall would decrease across the Sahel in Africa, the summer monsoon would weaken across Asia, and sea levels would rise even faster in the eastern US.

New Thermal Activity on Geyser Hill in Yellowstone National Park – Short video from the Yellowstone Volcano Observatory.

‘Perfectly Preserved’ Glassware Recovered From 2,000-Year-Old Shipwreck – The shipwreck was located 1,148 feet below the surface in waters between Italy and France. Two remotely operated vehicles (ROV) were used to scan the site and recover artifacts.

Short bursts of daily activity linked to reduced cancer risk - A total of just 4.5 minutes of vigorous activity that makes you huff and puff during daily tasks could reduce the risk of some cancers (i.e. cancers associated with physical activity such as liver, lung, kidney, gastric cardia (a type of stomach cancer), endometrial, myeloid leukemia, myeloma, colorectal, head and neck, bladder, breast and esophageal adenocarcinoma (cancer of the esophagus) by up to 32 percent.

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.

Humans taking a toll on Yellowstone wildlife - In recent days two black bears have been killed by motorists, an elk and a bison were also hit by vehicles, a newborn elk calf was picked up by motorists concerned for its fate, and a bison calf had to be put down after a visitor tried to help it out of the Lamar River so it could catch up with its mother. I remember that the park had good signage trying to educate people….seems that it isn’t as effective as I assumed it would be.

See the Rare Albino Echidna Spotted in Australia – It’s been named (Raffie) and photographed…evidently still in the wild! A piece of trivia from the article: a baby echidna is a puggle.

Tune in to the Great Salt Lake kestrel cam – Take a look…they hatched on May 17th…and they are growing up fast.

Scientists target human stomach cells for diabetes therapy – Still very much in research phase…but it would certainly improve the lives of a lot of people if it can be developed into a treatment!

This New Device Generates Electricity from Thin Air – Evidently the device can be made from any material that can be punctured with ultra-small holes. Too good to be true….or competitive with established clean energy sources like wind and solar?

Super low-cost smartphone attachment brings blood pressure monitoring to your fingertips – A clip that fits over the phone’s camera and flash…an app. It costs about 80 cents to make but the cost could be as low at 10 cents when manufactured at scale. Evidently it does not need to be calibrated either! I wonder if cuffs will become a thing of the past very quickly!

What we know about the health risks of ultra-processed foods – Research teasing out what exactly about ultra-processed food is bad. I’ve been trying to reduce ultra-processed food…so have been following the advice in this article for at about a year: if you're considering eating a packaged food, read the ingredient list…If you really have no idea what some of those ingredients are, it probably went too far.

You can make carbon dioxide filters with a 3D printer – Printing a hydrogel material that holds carbonic anhydrase (an enzyme that turns carbon dioxide and water into bicarbonate).

Nepal Won’t Move the Mount Everest Base Camp for Now, Despite Risks – Everest’s highest glacier has lost half its mass since the 1990s because of higher temperatures. It may only be a few years before the camp needs to move.

Colombia’s ‘cocaine hippo’ population is even bigger than scientists thought – Wild descendants of the hippos introduced in Columbia by Pablo Escobar….considered the largest invasive animal in the world. There are probably 181-215 of them in Columbia. Several strategies are being tried: contraception administered via dart, castration, exporting the animal to sanctuaries abroad. Culling appears to be the only strategy that can save the biodiversity of Columbia.

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.

Digesta: An overlooked source of Ice Age carbs – Partially digested vegetable matter from large herbivores (such as bison) might have provided carbohydrates and other macro nutrients reducing the burden of ‘gathering’ for a time after an animal was slaughtered. Perhaps during migration, it was the dominant source of carbohydrates in a situation with reduced accessibility of plants. And maybe women participated in hunting to a larger extent than previously thought; ‘grave goods’ in burials found that perhaps 30-50% of all large-game hunters in the Americans during the late glacial era may have been female!

Anemia found to be common in ancient mummified Egyptian children – CT scans were done on 21 child mummies (between ages 1-14 at death) to study the skeleton inside the wrapped remains. 7 of the children had pathological enlargement of the cranial vault, typically associated with anemia. The study also found a child that died less than a year after birth of thalassemia (the body could not produce hemoglobin).

Bathing through the ages: 1300 – 1848 – 14th and 15th century bathhouses provided services beyond bathing (lancing abscesses, pulling teeth, steam rooms, mineral baths, cupping, herbal concoctions); they helped shape the public health services of larger cities as they grew, and health conditions deteriorated. By the 16th century, bathhouses started to disappear as Europe was ravished by plague, smallpox, and syphilis. But – by the 1800s, sanitation reformers were arguing that making bathing facilities available to the poorest classes of society offered an ‘affordable and immediate way’ of improving public cleanliness and health. Bathhouses, along with waterworks and sewage systems, laid the foundation for the UK Health Act of 1848.

Glass or Plastic: which is better for the environment? – There is not a clear-cut answer. I will lean toward glass because of its non-toxicity….but I also realize we need to improve the ways we use it (less single use) and recycle it (better sorting and improved processing that avoids melting it twice),

Greener batteries – Batteries with Organic Electrode Materials (OEMs) are one alternative that is being researched…in this case using azobenzene by a research team at a Chinese University. Hopefully there are researchers around the world also focused on producing greener batteries.

Protein powders: When should you use them? – I think of protein powder as an ultra-processed food….a food I only want to use if I can’t manage to get enough protein from unprocessed or lightly processed foods in my diet. It is not something I want to use every day!

Long Reviled as ‘Ugly,’ Sea Lampreys Finally Get Some Respect – Not so long ago…lampreys were an organism that seemed destined for extinction because we only saw it as a predator that wiped out the Great Lakes lake-trout fishery. Now, the consensus is that, in their natural habitat, marine lampreys are “keystone species” supporting vast aquatic and terrestrial ecosystems. They provide food for insects, crayfish, fish, turtles, minks, otters, vultures, herons, loons, ospreys, eagles, and hundreds of other predators and scavengers. Lamprey larvae, embedded in the stream bed, maintain water quality by filter feeding; and they attract spawning adults from the sea by releasing pheromones. Because adults die after spawning, they infuse sterile headwaters with nutrients from the sea. When marine lampreys build their communal nests, they clear silt from the river bottom, providing spawning habitat for countless native fish, especially trout and salmon. Wow!

The Pacific Garbage Patch Is Home to Coastal Species—in the Middle of the Ocean – A surprise for researchers…they found shrimp-like arthropods, sea anemones and mollusks, Pacific oysters, orange-striped anemones and ragworms. Crustaceans were taking care of eggs and anemones were cloning themselves. This does not make the Garbage Patch acceptable!

Photography In the National Parks: Same Spot, Different Time / Season / Weather – Spots in Yellowstone, Mount Rainier, and Olympic National Parks.

Greater fat stores and cholesterol increase with brain volume, but beyond a certain point they are associated with faster brain aging – People in wealthy countries have largely grown accustomed to eating more and exercising less -- habits that are associated with decreased brain volumes and faster cognitive decline. This study looks at indigenous people (two tribes in Bolivia that live along tributaries of the Amazon). The tribe that was closer to our subsistence ancestors had the lowest rates of hear disease and minimal dementia; in this group - BMI, adiposity and higher levels of "bad" cholesterol were associated with bigger brain volumes in older adults!

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.

Arctic river channels changing due to climate change – The prediction was that Arctic rivers would be destabilized by atmospheric warming…that thawing permafrost would weaken riverbanks causing faster channel changes. Using 50 years of satellite data for areas of Alaska, the Yukon and Northwest Territories (which is experiencing the sharpest atmospheric warming due to climate change), researchers have discovered that greening of the area due to warmer temperatures has caused the riverbanks to be more stable…decreasing the sideways migration of river channels by 20% in the Western Arctic!

US Energy Storage Made Record Gains Last Year – A good new story! Something I didn’t know too: “they US remains the largest demand market for energy storage in the world.”

A pool at Yellowstone is a thumping thermometer – The water vibrates…the ground shakes. The intervals between reflects the amount of energy heating the pool at the bottom and how much heat is being lost from the surface.

Awe-Inspiring Videos Show Powerful Ospreys Diving in Pursuit of Prey – Photographer Mark Smith’s Osprey pictures/videos. I saw this post and the photographer was mentioned in the composition class I was views on the same day!

Crocodiles are uniquely protected against fungal infections. This might one day help human medicine too – Crocodiles have unique defensins (components of white blood cells and mucous membranes) that are inactive at neutral pH (as in the blood) but are active in sites of infection where the pH is lower (i.e. acidic). There is a lot more research and trials between this finding and application to humans.

'All work, no independent play' cause of children's declining mental health – The reduction has happened over decades. I was surprised by the quantification: “Between 1950 and 2010, the average length of the school year in the U.S. increased by five weeks. Homework, which was once rare or nonexistent in elementary school, is now common even in kindergarten. Moreover, by 2014, the average time spent in recess (including any recess associated with the lunch period) for elementary schools was just 26.9 minutes a day, and some schools had no recess at all.”

Mesa Verde National Park has plan to save Spruce Tree House – The area has been closed since 2015 because of concerns that layers of sandstone could peel away from the arch at any time. There is a lot of work involved and the plan is current open for public comment. When we visited Mesa Verde back in 1980, it was still open to visitors. Mesa Verde is still a National Park I would like to revisit.

Toxic red tide is back in Florida – Another deterrent to making a road trip to Florida….although it appears that right now there are no red tides in the panhandle…which would be the closest destination for us…I’m thinking maybe Pensacola.

Here Are the Incredible Winners of the 2022 World Nature Photography Awards – A little eye-candy for this week. ‘Fungus Horizon’ is my favorite.

Heat pumps for every home – A good introduction to heat pumps. I want a variable speed heat pump that uses the existing ducts in my house!

Archaeologists Uncover Hundreds of Colorful Sarcophagi at Saqqara—and They’re Not Done Yet – The seeming endless interest in Egypt…sustained by continuing new finds.

8 cool wild cats you probably don’t know – So many wild cat variations!

Fjords emit as much methane as all the deep oceans globally – When storms churn up water in fjords….oxygenating the fjord floor…methane emissions spike. If the water mixed more frequently the methane emissions would drop because anoxic environments at the bottom of fjords would disappear.

Tree rings are evidence of megadrought – and our doom – Tree ring data indicates that the 22-year period from 2000 through 2021 was the driest and hottest in the last 1,2000 years for the North American Southwest. There was another 22-year drought from 1571-1592 that was nearly as dry but not as hot as the current drought. And the water distribution allocations were made based on a 22-year period between 1900 and 1921 that we now know was an anomalously wet period for area! Not good signs for the future.

A 3400-year-old city emerges from the Tigris River – Drought lowered the Mosul reservoir. There was a quick survey…discovery ceramic vessels with 100 cuneiform tablets…and the conservation measures to project the site as the water rose again. The site is now completely submerged.

Fifty years later, Kim Phuc Phan Thi is more than ‘Napalm Girl’ – One of the most iconic photos of the Vietnam war…still makes be as emotional now as the first time I saw it. She says – To confront violence head-on…’the first step is to look at it.’

Two articles about the flooding in Yellowstone: Repairing and reopening Yellowstone National Park won’t be easy and Extreme flooding devastates Yellowstone, forcing the closure of all park entrances – Very sad….also scary.

Wildlife bedtime: weird nesting habits of North American wildlife – Black bears, black-footed ferrets, jumping spiders, bald-faced hornets, and red-sided garter snakes.

How Vivian Maier, the Enigmatic Nanny Who Took 150,000 Photographs, Found Her Place in History – Street photographer…that only became known after a storage locker of her photographs/negatives was auctioned off when she couldn’t make the payments on it.

Zapping orange peel oil into new, pleasant aroma compounds – I’ve always liked the smell and taste of orange peel (I buy organic oranges and use the whole orange!) but evidently the compound that is in orange peel, limonene, can be the starting platform for other scents as well.

Major infrared breakthrough could lead to solar power at night – A very small amount of energy was produced in the test…more research required for practical application.

Restoration Reveals Engravings in Egypt’s Temple of Esna – Follow the link at the top of the post to see a few more pictures of the restored engravings.

What we are still learning about how trees grow – A new study finds that tree growth is limited by cell growth rather than photosynthesis which has been assumed to be the limiting factor previously. The models that predict how much carbon forests can absorb need to be updated.

Spring Flowers are Blooming Earlier in Greater Yellowstone – The recovery of detailed records made in the 1970s by Frank Craighead of when flowers bloomed is helping document changes…help restoration planners determine the best seed mixes for native plants…try to mitigate the impact of climate change.

Cutting air pollution emissions would save 50,000 US lives, $600 billion each year – Yet another reason to take actions to dramatically reduce air pollution.

Traces of an ancient watery world in Capital Reef – Satellite views of Capitol Reef National Park…and the story in the rocks.

Prehistoric feces reveal parasites from feasting at Stonehenge – A piece of trivia: beef and pork were spit-roasted or boiled in clay pots but the evidence of particular parasites in coprolites reveals that liver and lungs from an infected animal were consumed raw or undercooked.

Vangelis, famed film composer and synth pioneer, dead at 79 – I remember going to see Chariots of Fire when it first came out in the early ‘80s….and the unforgettable music. This obituary post includes a link to a YouTube video with the music.

How cranberries could improve memory and ward off dementia – I like cranberries…but eating a cup (equivalent) per day is a lot. In the study they used cranberry powder.

More heat, more drought: New analyses offer grim outlook for the US west – The latest seasonal outlook projects the drought to continue across virtually the entire American west through the summer. New research suggests that Colorado, Utah, and Wyoming will increasingly look like the Southwest as temperatures continue to rise.

Why human brains were bigger 3,000 years ago – Some possible explanation: human populations reached a large enough size to share/divide labor and knowledge with others, writing….however, brain size/IQ relationship is not deterministic.

Operating rooms are the climate change contributor no one’s talking about – The health care industry accounts for 8.5% of all greenhouse gas emissions in the US. Operating rooms represent 70% of waste in hospitals and 3 to 6 times as much carbon as the rest of health systems.

Where tornadoes strike most frequently is changing – More erratic tornado activity and the broad impacts of climate change.

Do you have a lost twin? - The rate of twins among live births is only about 1.3%. But as many as 12% of all naturally conceived pregnancies may begin as twin pregnancies.

Wild fox kills 25 flamingos and a duck at National Zoo – We see foxes in our neighborhood. They seem to have adapted to the suburban environment. This one was very efficient to kill 25 birds, though.

A 10,000-year history of geo-ecological change in Yellowstone’s lower geyser basin – A study using a 26.5-foot core from Goose Lake.

US could cut transport emissions by 34% b 2030 – The current trend will reduce emissions by 19% but a bit more focus would provide a bigger reduction.

Garbology: How to spot patterns in people's waste – We’ve been getting rid of a lot as we prepare to move. I try to do as much as possible via donations and recycling…but there is still a lot going in the trash. Some of it came from Texas with us back in 1983…and was still in the same box!

6,000-Year-Old Slate Rings May Have Symbolized Relationships – Friendship rings? Careful analysis revealed the rings had been intentionally broken…and shared (i.e. pieces of a ring were found in two separate burial sites).

How Taipei discovered an active volcano on its doorstep – Disconcerting. Even of there is some ability to provide early warning of an eruption…could the city be abandoned quickly enough?

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.

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.

Old Faithful at Yellowstone (1880s-1909)

/

Internet Archive has 4 volumes of images of Yellowstone National Park produced by F. Jay Haynes from the 1880s to 1909. It is interesting to think about what it must have been like to visit the park during those early years. It would have taken a lot more effort to get there than it does today! At the same time – the facilities would have been minimal/primitive….there would not be crowds of people or problems with vandalism either.

I selected pictures of Old Faithful as sample images – a wonderful variety of depictions: 2 in color, 1 at sunrise. Each volume is well worth browsing for the other images as well.

Yellowstone National Park: in water colors (188?....the volume does not have a title or copyright page but presumably it was sometime after fall 1881 when he spent 2 months in the park and took over 200 photographs; he had a lease for a small photography studio in the park by 1884).

Yellowstone National Park: the world's wonderland (1889 with Truman Ward Ingersoll and Charles Frey)

Haynes souvenir album : Yellowstone Park (1909)

I’ve only been to Yellowstone once…and it was before I photography became a hobby…thinking about what time of year I want to go next time and hone my plans for the type of photography I want to attempt there.

Top 25 birds of the week: Predatory Birds – Starting out the gleanings list this week with birds…and photography.

The ingenious living bridges of India – Maybe other kinds of structures could be grown instead of built. The bridges look like Ewok structures from Star Wars movies!

Watch Over 150 Bison Weave Through Traffic in Yellowstone as Winter Migration Begins – I remember bison on the roadway during the early summer we went to South Dakota more than 20 years ago. It is an awesome experience to see them – using the car as a blind.

Chocolate: From Witchcraft to Miracle Worker in Early Modern Europe – A little history of chocolate as it was introduced to Spain.

More than ceremonial, ancient Chaco Canyon was home, new study says – I’ve only visited Chaco Canyon once…want to go again.

Richly Adorned Egyptian Tomb Could Rewrite the History of Mummification – Maybe….there is still testing to be done before the mummy in the tomb is confirmed to be old enough to be the man the tomb was built to hold.

Surprising Tales of Toxic Animals – I enjoyed the historical perspective in the information about several of the animals.

A diet of essential amino acids could keep dementia at bay – I wonder how long it will be before the patent for the supplement is awarded…..and it is released as a supplement. Hopefully there will be testing him humans beforehand.

This New Installation Pulled 20,000 Pounds of Plastic From the Great Pacific Garbage Patch – We need to stop producing messes….and clean up the ones we’ve already created. This is one attempt to start a massive cleanup of plastics that are in our oceans.

Bone-loss discovery points to new treatment for osteoporosis – I am glad there is ongoing research on this issue since the existing treatments don’t seem to work that well….often have side effects. Hopefully there will be more effective treatments by the time I might need them.

National Park Service Publications on Internet Archive

/

Last September - I browsed 18 publications from the National Park Service that have been scanned and are freely available on Internet Archive. They are all decades old….reflect history of the places. The oldest one is from 1917 (The National Parks Portfolio) which is clearly a snapshot from the early years of National Parks. I was particularly interested in the “Astronomy and astrophysics national historic landmark theme study” published in 1989 – the year my daughter was born and she has grown up to be an astrophysicist! The only park I visited before the publication was Yosemite; the publication is from 1990 and I visited in 1984. I’ve provided a sample image for each volume. Enjoy some armchair traveling with some browsing via Internet Archive…find some correlations in the publications and your own life.

Wind Cave, 1979

Agate Fossil Beds National Monument, Nebraska, 1980

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.

America’s First National Wildlife Refuge – Pelican Island National Wildlife Refuge….I’m including it in our plans for the next time we go to Florida; it’s about 1.5 hours to the south of Merritt Island National Wildlife Refuge which is always one of the places we visit in Florida.

Highly functional membrane developed for producing freshwater from seawater: A desalination membrane laminated with nanosheets featuring 2D nanochannels -- ScienceDaily – Still in the research stage. Maybe this is one of the technologies that will enable low-energy desalination - something we will need to avoid water shortages in many areas of the world.

A mild way to upcycle plastics used in bottles into fuel and other high-value products -- ScienceDaily and How Paving with Plastic Could Make a Dent in the Global Waste Problem - Yale E360 – Two articles about uses for the plastic waste that is overwhelming the planet right now. There still needs to be significant testing on plastic for paving: will it withstanding heavy traffic…will it shed microplastic particles, etc.

Pompeii's Museum Reopens With Dazzling Display of Archaeological Treasures | Smart News | Smithsonian Magazine – I enjoyed the article…and the website for the new museum.

A large number of gray whales are starving and dying in the eastern North Pacific -- ScienceDaily – Ongoing research but one explanation being explored in a decline in prey (i.e. amphipods) availability in their Arctic feeding grounds – maybe caused by warming there due to climate change.

For the Birds: Why Designing for Birds is Good for Everyone - News | Planetizen – Fast Company interviewed Tim Beatley about his book; he was one of the speakers at the Birds on the Niagara conference.

Wombats Poop Cubes, and Scientists Finally Got to the Bottom of It | Smart News | Smithsonian Magazine – Over 40,000 contractions as the feces moves down the intestine to shape a very dry cube. Evidently the cube shape is an indicator of wombat health!

Water Warning: The Looming Threat of the World’s Aging Dams - Yale E360 – Lots of people live downstream from big dams. Yikes! Decommission of dams is not easy…arguably it could be harder than the building of the dam originally.

Thousands of Wild Bee Species Haven't Been Seen Since 1990 | Smart News | Smithsonian Magazine – Most of the data came from Europe and North America….with some from the rest of the world. All of it sums up to a grim picture when it comes to bees.

Yellowstone's Hotspot Has Been Simmering For About 17 Million Years – An example of how continued data collection and study…can shift our understanding of geologic history even in areas like Yellowstone that have been studied for a long time.

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 Has Photography's Relationship With Nature Evolved Over the Past 200 Years? | Smart News | Smithsonian Magazine – A little history…that I used as a prompt to look for some of the works on Internet Archive. I’ll post about what I found for Kazumas Ogawa in a post next week.

Infographic: Deciphering Diet from Blood and Urine Samples | The Scientist Magazine® - Full article also available and more interesting that the infographic! The approach is still not perfected…but it may eventually help us get to personalized nutrition plans without as much trial and error that is required now.

Connection between gut bacteria and vitamin D levels -- ScienceDaily – Lots more needed to understand Vitamin D. This study indicated that blood tests for Vitamin D might not be useful at all since they don’t measure active Vitamin D….and active vitamin D is what correlates to gut bacteria…and potentially bone health. “Maybe it’s not how much vitamin D you supplement with, but how you encourage your body to use it.”

Get a Bird's-Eye View of UNESCO World Heritage Sites Across the Globe – Some beautiful places…from overhead.

How Non-Native Plants Are Contributing to a Global Insect Decline - Yale E360 – Insect declines….then birds. Lots of reasons to focus on planting natives a much as we can. I’m glad the forest behind my house is full of native trees and that I’ve replaced 2 bushs in the front of my house with natives. The challenge is to control the small but prolific invasive plants growing on the forest floor and into our yard enough for non-natives to survive. There used to be native jack-in-the-pulpits in our forest until several years ago.

How do we separate the factual from the possible? New research shows how our brain responds to both -- ScienceDaily – This article was frustrating. The study found that factual language is something our brains respond to. That’s not the issue at this moment in our nation’s history. The problem is the use of factual language about something not factual! Maybe this article is why we need to be more worried about public discourse/pronouncements.

It's One Hot Place Deep Down On The Floor Of Yellowstone Lake – About studies at Yellowstone Lake…the sensors and what they are revealing.

Shuttering fossil fuel power plants may cost less than expected -- ScienceDaily – Interesting…but I hope we’ll retire them all well before 2035 with the cost of renewals coming down so quickly. It will make economic sense to just do it!

Keeping Black Bears Wild And People Safe – This article is about black bears in Smokey Mountains National Park and the BearWise program more broadly. We do have Black Bears in Maryland and they occasionally show up in our area; there was one that showed up at our nearby elementary school a few years ago – caused a school lockdown until it wondered off.

Meet the Dipper, the Songbird That Swims – Evidently they are easier to spot in Colorado during the winter when they are concentrated long streams that remain unfrozen…but they are in the Rockies all year round…Dippers are elevation migrants (higher in the summer….lower in the winter). Maybe some post-pandemic trip we’ll look for them!

Ancient Artisans in Arabia, the Americas Invented Same Technology Independently | Smart News | Smithsonian Magazine – Stone fluting… and the fluting is not the same so it may have had a different purpose.

Baby boomers show concerning decline in cognitive functioning: Trend reverses progress over several generations, study finds -- ScienceDaily – The impact of modern life in the long term?

Ramesses II Statue Unearthed in Egypt - Archaeology Magazine – Multiple statues have been found…made of black and pink granite.

Top 25 birds of the week: #Waterbirds – Beautiful birds…not as many from North America as I expected.

Stone Sculptures of ‘Chronicles of Narnia’ Characters to Adorn Medieval Church – Replacing weathered carvings. There are 14 limestone carvings that will be displayed at ground level for visitors to see before being installed on the church’s exterior.

On the Delaware, A Promising New Era in Cleanup of an Urban River – Like many urban rivers in the US – a lot of progress has been made since the mid-20th century….but there is still a ways to go. Many of the urban rivers are clean enough in some stretches for recreational use….but often not after storms when sewage systems and extra industrial waste might be in the water along with the storm water.

Are you being served? A short history of waiters and servers in restaurants – Many of us are still in the mode of only getting carry out!

Examining the Chemistry of Yellowstone National Park's Thermal Waters – A little chemistry lesson in this post. Many of the hot springs and geysers are basic…mud pots and steam-driven fumaroles are acidic.

U.S. Commercial Rooftops Hold 145 Gigawatts of Untapped Solar Potential – The big challenge is logistical and financial. It seems that a partnership between commercial properties and community/utility solar would be worthwhile. It would be much better to use commercial rooftops than farmland for solar panels and many of the rooftops are in areas that consume a lot of electricity as well.

Record-Breaking 60,000 Flamingos Flock to Southern France -The picture of an adult flamingo surrounded by babies/juveniles caught my attention. I didn’t know that young flamingos are gray!

Unique Activities for Yesterday:

Flu shot. I got to my grocery store’s pharmacy just after they opened at 8:30 AM – got a flu shot. The store was busier than when I do my grocery shopping staring around 6:30….but it was still mostly possible to social distance…and everyone was wearing masks. I’ll stick with the earlier time for my grocery shopping.

Chasing Little Frost Trees in a Prairie Wetland | The Prairie Ecologist – We haven’t have many days for me to look for frost trees here in Maryland this year. This is always a matter of taking advantage of a frosty sunny day when it’s fun to look for interesting frost formations on exposed surfaces – grass – windshields, etc.

Stoneflies and mayflies, canaries of our streams – It’s great to see an article about the adult forms of the insects we collect as macroinvertebrates (larval form) when we do water quality monitoring either quarterly or with high school students on a field trip to a river.

Earthquakes in and around Yellowstone: How Often Do They Occur? – There are lots of them! About 5 that are strong enough to be felt have happened each year over the past decade.

Top strategies for successful weight loss maintenance-- ScienceDaily - Choosing healthy food, tracking what you eat and using positive self-talk….seems like common sense, but it is not ‘easy’ and so we struggle on. It comes down to making changes for the long term rather than just for a little while. New habits are always tough but, once truly habitual, become just the way be live our lives.  

Eero Järnefelt, painter of Finnish nature | Europeana Blog – Images of the natural world in the late 1800s. Koli National Park in eastern Finland was visited by the painter frequently.

Sustainable Farming Comes to America's Heartland | CleanTechnica – Iowa farmers…leading with their actions…responding to climate and environmental changes to farm better.

Can we heat buildings without burning fossil fuels? - BBC Future – Capturing heat from nearby places…using it for heating. It’s geothermal in the cities!

Bloom in McMurdo Sound – Green swirls in the water off Antarctica (some of the green color might be on the ice as well.

Camera Trap Chronicles: Cool Critters of New Hampshire – Maybe sometime  we’ll put our camera, currently pointed at the birdfeeder, in another location….see what comes into our backyard. I know we have deer but there could be other things as well. Our camera already picked up what looked like a racoon on our deck.

Top 25 birds of the week: groups of birds – Beautiful birds…a good ‘last addition’ to the gleanings list this week.
