The Mysterious Turkish Megaliths That Predate the Pyramids - Göbekli Tepe or “Potbelly Hill” in Turkish…it may be the world’s oldest calendar.

Planes, trains and monster diggers: The vehicles pushing the limits of electric power - BBC Future Planet recently went on a hunt for some of the biggest electric vehicles in the world – by size and weight. There is no shortage of impressive examples, from giant mining machines to trains and cargo ships. Often the largest excavators are connected to an electric power source by a cable, rather than using an on-board battery. But in terms of weight, heavy goods vehicles are among the largest EVs you might find yourself sharing the road with. Volvo's FH Electric truck, if you include its double trailer and load, is among contenders for the heaviest battery-powered electric road vehicle. Though research suggests we might one day see electric passenger aircraft capable of carrying as many as 90 people. The biggest electric planes today can accommodate a maximum of around nine passengers. The most powerful electric train in the world is perhaps the Shen24 in China. It is capable of carrying more than 10,000 tons – of coal – at up to 120km/h (75 mph).

Maine! Ghost Flower, the inside view – I’ve seen Ghost flowers a few times…but never the inside of the flower.

Crested Rats & Hairy Porcupines: Meet 7 of the World’s Coolest Rodents – The only one of the 7 I’ve seen is the Capybara (at the Dickerson Park Zoo in Springfield, MO).

A photographer captures life in America’s last remaining old-growth forests – What a great project photographer David Herasimtschuk had undertaken!

Plankton mark seasons in the sea, just like leaves and flowers on land – The seasonal flux of phytoplankton and zooplankton. The photo of diatoms (algae) in this post was what caught my attention; I’ve always enjoyed finding them in water samples.

14 Extraordinary Highly Commended Photos From the 2024 Wildlife Photographer of the Year Contest – My favorite was “Leaving the Nest” …two tawny owlets.

The Ancient Temple Carved Out of a Single Rock - Kailasa Cave, one of 34 in the Ellora Caves complex that has been cut and dug from the basalt rock of the Deccan plateau. 100 feet high and 300 feet long would make it the world’s largest—with all four sides liberated and sculpted into pavilions, halls, vestibules, towers, and courtyards by 800 hardy monks over 150 years beginning in the 7th century BCE. It was once painted white to mimic the Himalayan peak.

Thracian horseman’s grave unearthed in Bulgaria - The man was buried wearing clothing decorated with gold appliqués. A gold necklace, a gold diadem, a gold ring, and a knife decorated with gold and semiprecious stones were recovered from the burial, in addition to the remains of a horse and full battle gear, including a breastplate, sword, scabbard, and other knives and spears

Microplastics Found in Human Brains - The brains of people who suffered from dementia contained significantly more plastic than the brains of healthy people. Troublingly, the new study found more plastic in brain samples gathered in 2024 than in samples gathered in 2016.

Dragonflies Reveal Path of Mercury Pollution – Dragonfly larvae collected from 150 national parks and then analyzed for mercury revealed: in arid regions, mercury comes from snow and rain, while in wetter, more forested areas, airborne mercury clings to leaves, which then fall to the ground, where the toxin spreads.

Komodo dragons have iron-coated teeth to rip apart their prey – A clue to how dinosaurs like Tyrannosaurus rex killed and ate their prey.

COVID-19 devastated teacher morale − and it hasn’t recovered - A National Education Association survey of members found that, as of late 2022, a staggering 55% of educators were thinking of calling it quits because of: eroding sense of safety in the school, intense and unrelenting workload, lackluster leadership and changing expectations, and cuts in jobs and budget. Better pay is a start. I was disappointed that this article did not suggest more than that.

25 Stunning Images of the Cosmos from the Chandra X-Ray Observatory as It Celebrates 25 Years in Space - As NASA continues to grapple with a limited budget this year, Chandra is in danger of ending up on the agency’s chopping block and the program faces cuts in funding.

National Park Fun Facts: Petrified Forest – I’ve been to Petrified Forest National Park several times….still learned something from this post.

Art Bites: Michelangelo’s ‘David’ Was Carved Out of a Flawed Marble Slab – Some history of the famous statue.

8 Tips for Maximizing Your Home Solar Savings in 2024 – I am beginning to read articles like this…we will probably put solar on our house within the next year.

Why Covid-19 is spreading this summer – We’ve got to stop thinking about COVID as something that is like the flu…it isn’t.

Saving Dixie: 24 Hours Caring for a Wallaby Joey – The mother killed along a highway….and the Joey discovered alive…fortunately by someone who was willing to take care of him long enough to get him to an experienced wildlife carer.

Happy 50th birthday to the UPC barcode - While the world has changed a lot since the mid-1970s, the Universal Product Code (UPC) – what most people think of when they hear the word “barcode” – hasn’t. The code first scanned on a package of gum on June 26, 1974, is basically identical to the billions of barcodes scanned in stores all over the world today.

Intact Roman-Era Sarcophagus Discovered in France – From the 2nd century AD, sealed with iron clasps, weighs about 1,700 pounds. It hasn’t been opened yet, but x-rays and an endoscope camera have revealed the contents.

Selective removal of aging cells opens new possibilities for treating age-related diseases - Aging cells, known as senescent cells, contribute to various inflammatory conditions and age-related ailments as humans age. The researchers created technology that specifically targets organelles within aging cells to initiate the cell’s self-destruction. There is still a lot of work to be done (and preclinical and clinical trials).

Cloud Rings Around a Volcano Takes Top Prize in ‘Weather Photographer of the Year’ Contest – Capturing dramatic weather moments…

Brainless Jellyfish Are Capable of Learning - Experiments that provide evidence that box jellyfish are capable of associative learning, or the process of linking two unrelated stimuli together.

How maps can protect children from extreme heat - Heat is becoming increasingly dangerous and it's a threat that is not going away. Community heat maps may not solve the long-term problem, but they are a step in the right direction, by providing awareness and empowering vulnerable children and their families.

Stunning 16th-Century Turkish Bath Reopens in Istanbul - Called the Çinili Hamam, the revitalized site won’t offer traditional bathing until 2024. In the meantime, however, it will feature private gardens and contemporary art in the newly discovered Byzantine cisterns that originally fed the baths. Nearby, a new accompanying museum will display objects associated with traditional bathing rituals—including towels, bowls and ornately decorated wooden shoes—and explain the baths’ original water and heating systems. It will also showcase artifacts from the Byzantine, Roman and Ottoman periods uncovered during the restoration.

The Resiliency of Urban Wildlife - Four distinct sets of traits that help urban wildlife adapt and survive in environments that seem hostile to animals: diet, body size, mobility, and reproductive strategy. Important to know since if you look at the traits animals are adopting to survive in urban environments, you can see how cities could be modified to become more habitable to a wider variety of species.

See the Trove of Ancient Treasures, including a Shrine to Aphrodite, Just Discovered in an Underwater City Off the Coast of Egypt - Thonis-Heracleion was Egypt’s biggest port for centuries, before being surpassed by Alexandria. The city was eventually lost thanks to a combination of rising sea levels, earthquakes, and tsunamis, disappearing beneath the waves along with a large section of the Nile delta. It was largely forgotten for centuries, until 21st-century archaeologists began investigating.

New Patch Inspired by Octopus Suckers Could Deliver Drugs Without Needles - A tiny, drug-filled cup that sticks to the inside of the cheek like an octopus sucker. The device is easily accessible, can be removed at any time and prevents saliva from dissolving the drug, which gets absorbed through the lining of the inner cheek.

Buried ancient Roman glass formed substance with modern applications - Photonic crystals were created by corrosion and crystallization over centuries. If we could significantly accelerate the process in the laboratory, we might find a way to grow optical materials (i.e. materials for communications, lasers, solar cells) rather than manufacture them.

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.

Lake Springfield Boathouse/Meadow – August 2023 (2)

/

There was also wildlife to observe and photograph during our short walk at Lake Springfield boathouse and meadow. There were some very large funnel spider webs at the edge of the forest between the path and the lake. I didn’t see the spider…wondered if it was a larger than usual spider too. There was a very large round web (about a yard across) with a flower behind it…also on the forest side. Both were more visible because of small droplets from the fog that had recently burned away.

Grasshoppers were everywhere in the meadow. Occasionally it was possible to follow one as it jumped…and zoom in for a picture.

Pollinators were out and about too.

The high point of the morning was watching a pair of Indigo Buntings taking turns tending their young in a nest box. The box had been checked while we were walking by and the young were still there…but about ready to fledge.

Dragonflies were flying over the meadow looking for prey. Sometimes that sat long enough to be photographed.

A deer drank from a puddle in a low area at the edge of the meadow. It looked skinny for August with ribs showing as it walked away.

In the flowers near the boathouse, there seemed to be more butterflies than in the meadow. Butterfly weed and cone flowers are the big draw.

Zooming – July 2023

/

The photographic opportunities bulged with the addition of a trip to St. Louis along with the monthly trip to Texas…. local walk abouts in our yard and neighborhood…the Lake Springfield boathouse too. They all added up to a lot of zoomed images taken with my bridge camera (Canon Powershot SX70 HS). I enjoyed choosing which ones to include in this month’s post!

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 ground is deforming, and buildings aren’t ready – Underground climate change in urban areas where heat islands underground cause enough expansions and contractions to damage building foundations…particularly in older buildings.

How noise pollution impacts nature – A study out of Vail, Colorado, showed that increased trail use by hikers and mountain bikers disturbed elk so much the cows birthed fewer calves. Another out of Grand Teton National Park showed that backcountry skiers scared bighorn sheep during winter when food was scarce, with potentially lethal consequences.

Hospital understaffing and poor work conditions associated with physician and nurse burnout and intent to leave - The study from the University of Pennsylvania School of Nursing found that physicians and nurses, even at hospitals known to be good places to work, experienced adverse outcomes during the pandemic and want hospital management to make significant improvements in their work environments and in patient safety. The solutions to high hospital clinician burnout and turnover, they say, are organizational improvements that provide safe workloads and better work-life balance NOT resilience training for clinicians to better cope with adverse working conditions.

The simple ways cities can adapt to heatwaves – Heat monitoring and planning is become more important for cities…the climate emergency in cities is a health emergency.

New biodegradable plastics are compostable in your backyard – New plastic made from blue-green cyanobacteria that isstronger and stiffer than previous plastics from the same raw ingredient. They can be recycled…but also degrade rapidly in the environment.

Giant Hand Axes Discovered in England Point to Prehistoric Humans’ ‘Strength and Skill’ – More than 300,000 years old perhaps from an interglacial period. Early Neanderthal people inhabited Britain then…and maybe other archaic human species too.

Germs, genes and soil: tales of pathogens past – DNA sequencers and powerful computational tools…applied to ancient microbes…probing their role in human history. This article describes how the work is done, ethical considerations…using examples of what has been accomplished so far. The field of archaeogenetics is just beginning.

Back from the Dead: New Hope for Resurrecting Extinct Plants – There is a global effort to digitize herbaria specimens which had helped identify holdings of extinct plants…sometimes finding seeds. And then the challenge is how to best attempt to grow old seeds.

Pain risk varies significantly across states – Pain due to arthritis varies geographically in the US – with the moderate to severe pain being 23% in West Virginia vs 7% in Minnesota.  There is also a difference between people that did not complete high school…and those who obtained at least a bachelor’s degree – with the delta being greatest in West Virginia, Arkansas, and Alabama. There is a need to focus on the macro-level policies (i.e. generally at the state level) while continuing current individual interventions.

The Acropolis Adopts Crowd Control Measures for the First Time – The post-pandemic travel surge is overwhelming at some places – including the Acropolis!

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.

In 2050, over 800 million people globally estimated to be living with back pain: Analysis also dispels common back pain myth -- ScienceDaily – Attributable to occupational factors, smoking and being overweight. More common among older people and women. Current clinical guidelines for back pain treatment and management do not provide specific recommendations for older people. Low back pain continues to be the greatest cause of disability worldwide.

Why Are Some Wolves Black? The Answer Will Surprise You - Cool Green Science – There are more black-colored wolves in the southern Rocky Mountains…more gray coated wolves everywhere else. The black is from dogs that traveled with humans across the Bering Strait around 10,000 years ago, and those genes also make the black-colored wolves more resistant to distemper (which came with the conquistadors to South America).

We now know exactly what happens in nature when we fell forests -- ScienceDaily – When agriculture replaces forestry…a detailed study done in the Azores…substantiates the advise to plant native trees and flowers…stop mowing the lawn!

The viruses that helped to make you human - BBC Future – About 8% of the human genome comes from viruses but, curiously, there is not evidence of new endogenous retroviruses (ERVs) entering the human genome in the last few 1000 years (Koalas are being invaded by koala retrovirus with the viral DNA found in some populations but not others). The most studied human ERV is HERV-W; first described in 1999; genes that are essential for the placenta to form.

Algae in the Andes – Bursts of phytoplankton are not unusual in oceans, seas, gulfs, and canals. Now they are in lakes too….and potentially hazardous.

New Low Cost High Performance Perovskite Solar Cells – It appears that solar cells are on track to get better and better!

Communities should reconsider walking away from curbside recycling, study shows -- ScienceDaily – Maybe the trend of towns and cities across the US cancelling or scaling back recycling programs due to rising costs needs to keep recycling but focus on recycling materials with the greatest market value (newspaper, cardboard, aluminum/steel cans, HDPE/PET plastic bottles) and highest potential for carbon offset.

Does the roar of rocket launches harm wildlife? These scientists seek answers – Launches at Vandenberg have increased from 5-15 rockets per year to 50-100. There are biodiversity hotspots near launch sites in California, Texas, and Florida; the study at Vandenberg is intended to provide more insight about how launches impact wildlife. The study is funded for 3 years but may need a decade to understand some of the impacts.

Remains of Child Mill Workers Examined in Northern England - Archaeology Magazine – A study of 150 remains from a churchyard cemetery…many were young people between the ages of 8 and 20. They were pauper apprentices and their bones showed signs of stunted growth, malnutrition, rickets, and tuberculosis.

Turmeric: here’s how it actually measures up to health claims – Many of the health claims have only been proved in the lab or in animals. There are studies that show that turmeric has a modest benefit for pain compared to a placebo – but the studies are often on small populations and there is a wide variation in the amount of turmeric participants were given. There is not enough research to firmly support any of the claims…although it is a great spice (flavor and color).

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!

Farmers Find Wild African Cat Wandering Around Missouri – A serval found when a farming family set a live trap to capture the culprit leaving bones and feathers between their stacks of hay bales! The Turpentine Creek Wildlife Refuge came to the rescue. This is all close to where I live and I was saddened that evidently the new Big Cat Public Safety Act does not include the smaller non-native wild cats…and that someone was cruel enough to release this cat of the African savanna into the wild in Missouri.

Caribou have been using the same Arctic calving grounds for 3,000 years – Analysis of antlers found on the tundra….discovering some of them are 3,000 years old! But the Arctic is warming faster than other parts of the globe. The elders of the village south of the calving grounds comment that they have noticed a lot more trees, less barren tundra. What will happen to the barren ground caribou as this habitat gets converted to forest?

Why fabric fraud is easy to hide – The fashion supply chain is fragmented and very dense….most apparel companies do not track their own supply chain (or don’t go past their immediate suppliers). Organic cotton is one of the prime examples of how end products labelled as organic cotton…might not be. It is hard to determine where the fraud is inserted in the process; the result is that the consumer is paying a premium price…not getting what they are paying for. And to improve the system will require big changes in the fabric/apparel business.

A Field Guide to Unexpected, Out-of-Place Wildlife – Sometimes animals have ranges that are changing or are a lot larger than we anticipate…sometimes birds are in very different places that their usual range!

Dirty Laundry: How much microfiber do we emit with our laundry – A study done in the UK…but probably relevant to the US as well. Microfibers from laundry in the UK weigh 6,850 to 17,847 tons per year. Yes…that’s a lot and pollutes water…however, it is a dwarfed by the 365,000 tons of clothing going into UK landfills per year.

Antibiotic use in farming set to soar despite drug-resistance fears – The increase in bacterial infections that cannot be treated with antibiotics (because of bacteria developing resistance to antibiotics) has been growing in recent years. Overuse of antibiotivs in agriculture is thought to be a major driver of the problem. Governments around the world have attempted to curb the use of antibiotics to promote growth but the use is still expected to grow by 8% between 2020 and 2030. The article includes a chart of agricultural antibiotics by country in 2020…and a projection for 2030.

The Lifelike Glass Models of Leopold and Rudolf Blaschka – Thousands of realistic models of plants and sea creatures made by a father and son from the 1860s until 1938.

8 everyday foods you might not realize are ultra-processed – and how to spot them – I am cutting back on ultra-processed foods this year. Some of the 8 listed in this article are easy: I don’t eat breakfast cereals, I only eat protein bars as ‘emergency rations’ (i.e. not frequently) and avoid yogurt, meal bases and sauces, processed meats, and margarine. I’m still looking for a soy milk that has fewer ingredients; will give up on soy milk soon if I don’t find one. And I try to buy bakery bread.

Did Philip II bring invasive fish to Spain? – Evidently his efforts to acquire fish and crayfish from afar spanned at least 25 years!

Study reveals that much still not known about cognitive decline - Data came from 7,068 participants in the 1996-2016 Health and Retirement Study. Participants were born between 1931 and 1941. Researchers measured their cognitive functioning at age 54 and how it declined until they were 85. At age 54, socioeconomic status, education and race -- explained only 38% of the variation in functioning. Those same factors explained only 5.6% of the variation in how quickly cognitive functioning declined in people between age 54 and 85. So much we don’t know about cognitive decline although it is pervasive in older adults, even those without dementia.

Milk packaging influences its flavor – Light blocking containers are best….and plastic/glass is better than paperboard. So why aren’t paperboard cartons being phased out (they are also harder to recycle than plastic milk cartons).

Clean Energy Saw as Much Investment as Fossil Fuels for the First Time in 2022 – Good! And hopefully this will continue to be the case…and we don’t allow any fossil fuels to be counted as ‘clean.’

What Secrets Lie Beneath This 17th-Century French Aristocrat’s Smile? – Decaying teeth and an ivory prosthesis (in front) held in place with gold wire….and a woman kept her smile and place in society.

A curious Colorado bear strikes a pose for 400 selfies on a wildlife camera – A bear that noticed the camera!

Leprosy: the ancient disease scientists can’t solve – There is treatment…but diagnosis is complicated and there is no cure. And we still don’t know how it is transmitted.

Researchers find rare 17-pound meteorite in Antarctic ice – A team spent a week and half in the Antarctic summer (14 degrees Fahrenheit…so still very cold) sleeping in tents and riding snowmobiles to search for meteorites. They found small ones….and a big one!

New mosquito repellents that work better than DEET – Maybe the next generation mosquito repellent?

In 2021, 20% of electricity in the US was generated from renewable sources – And wind surpassed hydroelectric in 2019 as the predominant renewable source. Hopefully, the percentage of electricity from renewables will go up quickly in the coming years.

Three grizzly bears tested positive for avian flu in Montana - The animals were euthanized in the fall; suspected to have rabies, they tested negative. But they were positive for avian flu. The bears were ‘in poor condition and exhibited disorientation and partial blindness, among other neurological issues.’ So – the current outbreak of avian flu that has impacted wild and domestic birds (more the 52 million have been killed or culled to contain the virus) is impacting more than birds.

Drone video of moose shedding its antlers – Wow – it happened so quickly; the video is only 16 seconds! The moose just shakes its body, and the antlers fall off. It seems to want to leave the scene quickly once they are off too.

How an asteroid impact would transform the food we eat – Thought provoking…and scary. Right now, I am beginning to wonder how the level of drought in the US is going to change the food we eat…or will we eat the same way but pay much higher prices.

A Field Guide to Unexpected, Out-of-Place Wildlife – Why wildlife shows up in the ‘wrong’ place… I had read about the shifting range of armadillos last spring (was reminded of it by the reference to the Virginia opossum in this post).

State Of the Birds Report: More Than Half of U.S. Bird Species Are Declining – Sad….another indicator that the Earth is changing.

Economic losses from hurricanes become too big to be offset by the US if warming continues – I’ve been wondering about this since Hurricane Harvey and finally there is some analysis of the data…but, so far, it does not seem to be changing the way we deal with the aftermath of these catastrophic storms. The dominate idea still seems to be ‘rebuild.’

Life expectancy improves in some countries after big drops in 2020 – but US and others see further falls  - The life expectancy at birth in the US was 79.8 in 2019 and was down to 77.4 in 2021. It might take a few years until the impact of COVID-19 on life expectancy is fully understood. It seems to me that there are other cultural changes that happened concurrent with the COVID-19 pandemic that could impact life expectancy in the US into the future: reduced vaccination rates, reduced trust in medical professionals, increased belief in whatever is said on social media and conspiracy theories, increased stress/mental health challenges, etc.

The Clean Water Act at 50: Big Successes, More to Be Done – The Act was passed the year I graduated from high school. I had done a project about algae as pollution indicator in the streams around Dallas, Texas in the fall before so I was aware of water pollution issues of the time. It is frustrating that there is still so much to be done….

New model of Alzheimer’s as an autoimmune disease – A new perspective….maybe leading to new therapies in the future.

Ancient Maya Cities Were Polluted with High Levels of Mercury – The Maya coated surfaces (walls and floors and bodies) with cinnabar…and the mercury from that leached into the water supply and soils. Chronic mercury poisoning causes tremors, weakened vision and hearing, and paralysis! The contamination at some sites is high enough that archaeologists need to use mitigation techniques and protective gear.

Young kids avoid one learning trap that often snares adults – Young kids are not as good at focused attention as adults which means they notice new things happening away from a ‘focus area’ more quickly…..but focused attention can also mean learned inattention in adults which might not be the best strategy in all situations.

After Three Summers, Man Finally Gets Photos of Hummingbird with Rainbow Wings – Beautiful pictures. They prompted me to look up why hummingbird feathers can show the colors of the rainbow. I found a Science Daily post from back in 2020 that offers an explanation.

London, Ontario: Carpenter Ant

/

My daughter and I waited for the warmest afternoon to eat outdoors at Morrissey House near our hotel. Shortly after we sat down, a small insect flew onto the menu. A case of wildlife in the city of London, Ontario! I began to take macro images of it and then realized it was shedding its wings! It looked like an ant to me. My daughter commented that it could be a termite.

The sequence above happened over less than a minute! The waitress returned and took the menu – ending my photographic opportunity.  

A little research using the photos….and I concluded that it was a carpenter ant.

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.

Josey Ranch Lake After a Heavy Rain

/

I headed over to Josey Ranch Lake (Carrollton, TX) late in the day when the heavy rain finally stopped. Lots of water was still running off into the storm drains on the streets during the short drive; I avoided the curbside lane when I could. My goal was to see if the nesting mute swans at the lake had a cygnet.

When I got there, one of the swans was out on the lake – doing a lot of preening.

As I got closer to the area of cattails where the nest was located, there was a sheen of water running over the sidewalk and part of the boardwalk was under water. The white blob in the cattails is the second swan.

2021 05 IMG_7391 (2).jpg

I zoomed in on the blob. The camera focused on the cattails, but the second swan is identifiable. There is a second bird in the picture too…more about that one later.

2021 05 IMG_7391 (8).jpg

I walked further around on the paved bike path, stepping around the drifts of silt and trying not to splash water into my shoes. I found a little better vantage point to watch the second swan. The bird was picking up soggy sticks and dried cattail leaves…trying to pile them up again…frantically moving about as the vegetation sank into the water. Oh no! There must have been about 6 inches of water where the nest had been. The nest had been flooded. No cygnet…no egg…no nest.

2021 05 IMG_7391 (14).jpg

The bird that had been on the lake moved onto the bank still preening. The two birds were responding to the stress of the nest flooding very differently. I wondered which one was the male and which was the female. Was it early enough in the season that they will build another nest and try again?

 Now for the other bird that was near the swans’ nest – a juvenile Little Blue Heron that I had seen previously at the lake. It was standing in the cattails…observing the scene. It had more blue feathers since I saw it a few weeks earlier. The color of the beak and eye ring looks very striking on this young bird. As I looked at my pictures of the bird on my larger monitor, I wondered if the bird had a damaged wing or if it was simply wet. I’ll have to go to the lake again before I leave Texas to find out.

There were a few Mallard Ducks. It appears they already have 4 young with them….juvenile size rather than ducklings! They were on the shore rather than in the water the whole time I was there.

Rounding out the birds I noticed but didn’t take time to photograph - pigeons and grackles. There were people venturing out for exercise; some had already made it around the lake and commented about the water gushing from the dam on the other end. Others arrived while I was there. It was a quick outing. I was sad about the swan’s nest…. felt privileged to observe the birds’ response to their tragedy from a distance.

Hawai’i Island Festival of Birds

/

Wow – 5 days of the virtual Hawai’i Island Festival of Birds. Like the other virtual festivals we’ve seen….I want to go to the Hawai’i festival some year…the sooner the better! When we travelled to the big island in 2015, it was before we’d been to any birding festivals and I took only a few (poor) pictures of birds.

When we go back – I’ll be more prepared after having the experience of this virtual festival. My cameras (and photographic skills) are better than in 2015 too.

The sessions were pre-recorded and not as lengthy some of the other festivals. This was the only festival where native names and language (Hawaiian) were an integral part of the festival.

I listened to all the sessions…even the ones that were readings of books for children about Hawaiian birds….and I learned something from them all.

Day 1 was the longest because I also watch the two virtual field trip sessions:

  • An interview with the authors/photographer for the Field Guide to the Birds of Hawai’i…how it was put together and introducing a topic woven throughout the conference - the extinctions of native birds and actions to help the surviving species

  • Natural history and status of Hawaii’s seabirds….the impact of sea level rise on Midway Atoll where 91% of seabirds nest in Hawaii…and translocation projects to higher islands (islands within islands to keep mammalian predators out of nesting areas). Pacific Rim Conservation

  •  A Virtual Tour of Hakalau Forest National Wildlife Refuge…only place in Hawaii where native forest birds are stable and increasing…We’d get a guide or go with a tour group from the festival when we go. Birds are hard to see in the forest!

  • A Virtual Tour of Kaulana Manu Nature Trail … newly opened…off the saddle road on the big island. There is good signage and it’s something we could do on our own. There was a decontamination station for cleaning boots; there is a fungus that causes Rapid Ohi’a Death…a tree that many native birds depend on.

  • The status of eBird, Merlin, and Community Science in Hawaii….I need to remember to load Merlin’s Hawaii pack before we go!

  • Choosing the best binocular for You!...some binoculars have a short enough minimum focus distance that they can be used for butterfly watching; I quickly decided that, for me, I’d rather use my camera’s zoom to get close images of butterflies rather than watching them through binoculars. But – I did hear about Insect Shield Scarves…which might be something to have for warm weather birding!

Day 2:

  • Marvelous Moli…The albatross…The speaker wrote a book – Holy Moli….If we want to see them on nests we’ll have to go to Kauai. Maybe the festival will have a field trip for that.

  • Kolea…Pacific Golden Plover…learned a lot about how tagging has evolved over the years and how sophisticated tagging has shown how long and exact their migration is. The book by the speaker found here.

  • Hula and storytelling….listening and watching…like a meditation

  • Albatross of Kauai, the story of Kaloakulua…a particular Laysan Albratross from 2013/2014 season

Day 3:

  • Papahanaumokuakea Marine National Monument…a big place…not sure how we would ever be able to visit

  • Garbage guts…a children’s book about plastic garbage in the sea and a Laysan albatross

  • Tracking the endangered ‘Akiapola’au…with transmitters and receivers in the Pu’u maka’ala Natural Area Reserve. I remembered that my daughter and I walked around part of that reserve in 2015. I didn’t photograph any birds, but I did take one of my favorite pictures of the whole trip just as we left the fenced area heading back to the car – a camellia among tree fern fronds

2015 12 IMG_7720.jpg

Day 4:

  • Albatross…doing nest counts….they live very long lives (there is a female that was tagged in 1956 on Midway Atoll that is still producing healthy chicks there!)…World Albatross Day was June 19, 2020

  • A Perfect Day for an Albatross (book)… the author talked about producing the book and demonstrated her block print technique before the book was read by 2 educators at Kauai

  • Manu, the Boy who Loved Birds (book)…author talking with the publisher and the expert that helped with the book…and then a reading of the book…thinking about recent extinctions and what we can do to help surviving species in Hawaii

Day 5

  • Hawaii Wildlife Center…bird assistance/hospital and conservation programs…I learned that warm water is required if birds need to be washed because their normal temperature is higher than ours and if they are injured/oily/emaciated, they will go into shock if washed with room temperature water!

  • Manu-o-Ku (white tern) nesting in Honolulu…what happens when the chick falls out of the nest? Most of the time, volunteers are called and it’s put back in the nest or in the tree close to the nest…and the parents welcome it back!

  • No Ka Manu Hea Keia Nuku? (To which bird does this beak belong) (book) – In Hawaiian and about Hawaiian birds! It was a great finale to the Festival.

And after all the joy of the videos, I won a drawing for a festival swag pack that will be coming in the mail! The virtual festival was a great addition to our mid-October during this pandemic year!
