10/06/2026 Smithsonian Magazine New Research Shows That These Ancient Egyptian Servants May Have Been Brutally Sacrificed and Buried Alongside Their Pharaohs - Forensic research has identified deliberate and fatal wounds on skulls from simple grave sites near First Dynasty royal tombs in Upper Egypt. by the beginning of Egypt’s Second Dynasty, around 2730 B.C.E., subsidiary graves had all but disappeared.

10/06/2026 Planetizen NYC’s landfills will soon overflow — expanding them invites health risks -New York City’s trash will exceed its landfill capacity within 16 to 25 years. The landfill is already the single largest source of methane emissions in New York state.

10/06/2026 Yale Environment 360 Caribbean Nations Have Installed Twice as Much Solar as Official Figures Suggest - In the Caribbean, energy shocks are particularly pronounced as island nations with little in the way of fossil fuel reserves are heavily dependent on imports. Renewable energy offers a cheaper alternative. Across the Caribbean, people have installed roughly twice as many solar panels as official statistics would suggest. A new report calls on countries to make it easier for new solar installations to connect to the grid.

10/03/2026 Clean Technica Texas PUC Greenlights Coal Plant Closure & Renewables Construction - The Texas Public Utility Commission (PUC) ruled that Southwestern Public Service Company (SPS) can proceed with closing its Tolk coal plant near Lubbock and constructing renewable energy and battery storage to provide reliable, clean electricity to Southwest Power Pool customers. When Tolk closes, it will save abundant water in a drought-prone region, millions of ratepayer dollars, and eliminate millions of tons of harmful pollution every year, making rural West Texas a healthier place to live.

10/03/2026 Science Daily Vitamin C linked to fewer deaths in blood disorder trial - In a phase 2 trial of people with precancerous or low risk blood cancers, daily vitamin C did not slow abnormal cell growth, but it was linked to favorable changes in inflammation and fewer serious complications. An exploratory follow up also found fewer deaths among participants taking vitamin C than among those receiving placebo.

10/2026 Archaeology Magazine A change in Fashion - Ken Hill stands out from the otherwise flat terrain of Norfolk County on England’s east coast. The site is now recognized as having yielded the greatest assemblage of prehistoric jewelry to have been found anywhere in Europe. They may be evidence of a society-wide ritual of retiring an old-fashioned symbol of authority by burying it.

10/07/2026 The Conversation Rising seas threaten the world’s migratory shorebirds - Among the 37 studies that we examined, 21 predicted negative impacts of sea-level rise on shorebird habitats such as declines in habitat area or quality, while 17 predicted negative impacts on shorebird populations or individuals such as decreased survival or abundance. Sea-level rise is expected to drive substantial habitat loss at many sites of international importance for migratory shorebirds. These include San Francisco Bay and Humboldt Bay in the United States, the Colorado River Delta and Marismas Nacionales in Mexico and the Yellow Sea region in East Asia, each of which supports 150,000 to more than one million shorebirds annually. Urgent action will be required to preserve shorebirds and their fascinating migrations for generations to come.

10/7/2026 BBC Future Inside an active Antarctic volcano, gentoo penguins are flourishing with climate change - The global population of gentoos increased by around 11% between 2013 and 2020, with more marked increases along the Western Antarctic Peninsula at 23%. A suite of traits help gentoos deal with climate change. They're not fussy eaters – unlike their two closest relatives, they'll switch their diet from krill to fish and back again depending on what's around. And if their eggs are destroyed by a sudden flood or a freak snowstorm – something growing more common with climate change, Lynch notes – they can simply lay more eggs. Despite its eruptions and industrial past, Deception Island remains a unique wildlife hotspot. The outside of Deception Island is one of the most stunning amphitheaters of penguinness that we have in the Antarctic.

10/7/2026 Clean Technica The Solar Century: Landmark Moments in the History of Solar Energy - Since the creation of the first silicon solar cell 70 years ago, solar leaders have been innovating, improving efficiency, lowering costs, and growing this American-born technology into an essential part of our nation’s energy system. In 2025, solar and storage accounted for 79% of new electricity generating capacity added to the grid, and the industry employed over 260,000 Americans. In May of 2026, solar energy generated more electricity than coal for the first time in American history.

10/7/2026 Smithsonian Magazine A Ship Carrying Stacks of Ancient Dishware Sank Off the Coast of Turkey 2,100 Years Ago. Its Ceramic Cargo Is Still Remarkably Intact - Stacks upon stacks of plates; bowls; and trays purpose-built for different foods, such as nuts, fish and soup. The amphorae were probably made on the Aegean Islands, while the bulk of the plates and bowls were likely manufactured in the port of Rhosus, now the Turkish city of Arsuz.

How long will you live? New evidence says it’s much more about your choices than your genes - Environmental factors influence health and longevity to a far greater extent than genetics. Environmental factors had the greatest impact on lung, heart and liver disease, while genetics played the biggest role in determining a person’s risk of breast, ovarian and prostate cancers, and dementia. The environmental factors that had the most influence on earlier death and biological ageing included smoking, socioeconomic status, physical activity levels and living conditions.

'The ice melted beneath our feet': The huskies that revealed the rapid shrinking of Greenland's ice - Greenland experienced record ice loss in 2019, shedding a total of 532 billion tones from its giant ice sheet, according to a 2020 study. On average, Greenland loses 234 billion tons of ice per year. What's distinctive about Greenland is how much melting happens on the surface in the summer, because Antarctica doesn’t get anywhere near as much.

Humboldt Penguins on the Edge – Temperate penguins of Chile and Peru. They hunt in the cold, nutrient-rich waters of the Humboldt Current, the world’s largest marine upwelling, that flows a few miles offshore. They are excellent swimmers and deep divers in their pursuit of anchovies and other fish. Humboldt penguins have come back from the edge of extinction before—it will take the continued efforts of local communities, governments and partners to bring them back again.

Study: 'Sustainable intensification' on the farm reduces soil nitrate losses, maintains crop yields - A nine-year study comparing a typical two-year corn and soybean rotation with a more intensive three-year rotation involving corn, cereal rye, soybean and winter wheat, found that the three-year system can dramatically reduce nitrogen -- an important crop nutrient -- in farm runoff without compromising yield.

These Everyday Artifacts Tell the Story of Harriet Tubman’s Father’s Home as Climate Change Threatens the Historic Site – The site is in Blackwater National Wildlife Refuge – the first place I saw a bald eagle in the wild (in the early 1990s). My family visited there many times when we lived in Maryland, and we observed the transition of the marshes to ghost forests and then then open water over the next 30 years. The refuge is obviously changing with rising sea level.

Plastic recycling gets a breath of fresh air - The researchers used a molybdenum catalyst and activated carbon -- both of which are inexpensive, abundant and non-toxic materials. The mixture with PET was heated and, after a short period of time, the chemical bonds within the plastic broke apart. With the tiny bit of moisture from air, the material turned into terephthalic acid (TPA) -- the highly valuable precursor to polyesters. The only byproduct was acetaldehyde, a valuable, easy-to-remove industrial chemical.

This English Burial Site May Be Centuries Older Than Stonehenge - Flagstones, a burial site in Dorset, on the English Channel, may be the earliest known large circular enclosure in Britain. It is a perfectly circular ditched enclosure, with burials and cremations associated with it and may have even served as a prototype for later sites such as Stonehenge, which is located just 45 miles to the northeast. The ditched enclosure was created around 3200 B.C.E., with burials placed in it at that time. The scientists were also intrigued to find that a young man was buried under a large stone at the site fully a millennium later.

Climate change threatens future of banana export industry - It will be economically unsustainable by 2080 for many areas across Latin America and the Caribbean to continue growing bananas for export, because of rising temperatures caused by climate change.

Spring Spectacle: Thousands of Tulips Bloom at One of LA’s Top Gardens – Reminds me that I need to plan a visit to the botanical gardens near where I live in Missouri for tulips soon!

Portraits of women who 'shine a light': from an 'analog' astronaut to a watermelon farmer – Vignettes of women from around the world…what a range of activity!

Restored Glass Negatives Capture Daily Life in 19th-Century New England – Photographs taken from the 1860s to 1930s….Massachusetts…different photographers.

As Temperatures Rise, Dengue Fever Spreads and Cases Rise – The mosquitos that carry dengue viruses are extending their range. There were 0.5 million cases in 2000…5.2 million in 2019. In recent years, dengue has popped up in places it had never been seen, including Afghanistan, parts of Southern Europe, and, this year, Chad. An additional 2 billion people would be at risk of dengue exposure by 2080, compared to 2015. Areas unfamiliar with dengue may be hard hit even if case numbers aren’t high as people won’t have immunity from previous exposure to the virus, and public health systems may not be strong enough to cope with dengue outbreaks.

The World’s Largest Iceberg Is Drifting Three Miles Into the Ocean Each Day - The world’s largest iceberg, which had been grounded on the seafloor since the mid-1980s, is moving away from Antarctica and picking up speed. It could disrupt the foraging of seals, penguins and other seabirds. Called A23a, the iceberg measures around 1,500 square miles—more than 20 times the size of Washington, D.C.—and it’s roughly 1,300 feet thick, making it two and one-third times the height of the Washington Monument. It weighs nearly one trillion metric tons.

Landscape Photography Awards Rewards Authenticity in Photography – My favorite was “Little Leaves”….maybe because it didn’t have time to see a lot with fall foliage this year.

Expansive Alexander Calder Exhibition Opens in Seattle – Take a look at the museum’s site for the exhibit at well.

Bird Photography Contest Celebrates the Unique Diversity of Australia’s Wildlife - Nine winners were singled out for their work, rising above more than 6,000 images that were submitted. My favorite of this group is “Jambalaya on the Bayou.”

Volcano Monitoring Can Be A Risky Business: How Scientists Work Safely - Common PPE used in the field by HVO staff include respirators to filter volcanic gases, gas badges to monitor sulfur dioxide (SO2) concentrations, along with helmets and eye protection.  When molten lava sampling, crews will carry a face shield, fire-resistant clothing, and gloves to protect the wearer from radiating heat.

Best of 2023: Top 42 Photographs From Around the World – I have two favorites in this group of photos: the bald eagles and the dancing mantises!

African Penguins Tell Each Other Apart by Their Polka Dot Patterns – Evidently the chest plumage is unique to each bird….and the birds recognize the dots of their partners!

Photographer Chronicles the Enchanting Life of a Wild Red Fox for 8 Months – A Hungarian photographer’s project at his cottage in the forest after he noticed a fox running under the window one night.

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.

Why the Dutch embrace floating homes – Maybe other coastal areas around the world should be looking at this kind of development…or mitigation strategy. Otherwise - there is going to be a lot of migration away from coasts that will become more and more prone to flooding in the decades to come.

New Antarctic Penguin Colonies Discovered Further South than Normal – Good news for the Gentoo penguins - there is more space on Antarctica now; previously the areas were too icy for these birds. On the downside – there is less area suitable for penguin species that previously lived there and there might be less food available for them all as warming continues.

Three people with spinal-cord injuries regained control of their leg muscles – There has been a lot of research in this area over the past decade; perhaps we are coming to a point where rapid advances are going to be made.

Why to flickers knock on your house? – Not just why they knock but other interesting behavior…made me consider putting up a flicker box to give them a place to raise young.

Dog feces and urine could be harming nature reserves – A study providing rationale for requiring dogs on leashes and owners removing their dog’s feces in natural areas.

Top 25 birds of the week: February 2022 – My favorite this week is the Great White Pelican. Somehow pictures of birds from the front like this always give them a rather assertive appearance.

US household air conditioning use could exceed electric capacity in next decade due to climate change – Not good. Implementation of mitigation strategies need to ramp up quickly. As an individual homeowner, I am thinking: 1) increase efficiency (heat pump or geothermal, more insulation, solar screens on any window getting full sun sometime during the day, maybe upgrade windows/doors) and 2) solar panels on the roof with storage battery.

Threats from QAnon conspiracists force butterfly sanctuary to close – Sad. My husband and I visited the butterfly sanctuary on a rainy day during the Rio Grande Birding Festival in 2017; it wasn’t a good day for butterflies, but we always thought we’d come back on a warmer/sunnier day during some future visit to the area --- then the border wall and the conspiracists has ended it all.

More spice could help seniors avoid salt – Yes! Lemon pepper (the kind without salt in it) is one of my favorites…and any of the components that come under the heading of ‘Italian seasoning.’ I dry my own orange peel (any time I eat an organic orange…the peel gets processed and dried). It helps to use fresh ingredients too (i.e. avoid no-salt version from cans…they have never tasted good to me no matter how they are prepared).

Star Bright: What are Dark Sky Reserves? – Staunton River  (where we’ve been for ‘star parties’) is a Certified IDA International Dark Sky Park….maybe we’ll visit one of the Reserves post-pandemic. Right now – the closest one to us is the one in Canada (just north of Vermont/Maine).

Top 25 birds of the week: Bird Interactions! - Wild Bird Revolution and Top 25 birds of the week: Raptors!  and Top 25 birds of the week: Feathers!  – A treat this week – 75 bird photographs – enjoy!

The unseen 'slow violence' that affects millions - BBC Future – The harms that happen so slowly that we don’t notice in the moment. It happens over months and years and decades (maybe even centuries). We notice as we use our ‘big data’ to see hot spots of ill-health, where the environmental degradation is at it’s worst, and populations that can’t seem to escape their dire situation. And the issue very quickly becomes – how does our culture respond to the awareness of that ‘slow violence.’

Carbon: Getting to net zero -- and even net negative -- is surprisingly feasible, and affordable -- ScienceDaily – A detailed model of the entire US energy and industrial system….showing how to achieve carbon neutrality by 2050…with particular emphasis on what needs to happen in the next 10 years.

The country rejecting throwaway culture - BBC Future – France has introduced an index of ‘repairability’ rating for appliances…hoping to increase the electronics repair rate to 60% within 5 years. I’m glad I opted to repair my clothes drier rather than replace it….although the repair (replacing of the failed heating element) produced some trash it was a lot less than the whole appliance! Things like phones and laptops and monitors are harder.

Carolina Wrens Will Nest in Just About Anything and Why Carolina Wrens Have Moved into Your Neighborhood – We had a Carolina Wren make a nest in a gas grill we hadn’t used in along time. It surprised me when I opened the lid and the bird – startled and then panicked – flew out onto the deck railing. There is usually a pair nesting somewhere around our yard; we see them when they come to the feeder and hear them even more frequently. The forest behind our house and the brush pile at the edge of the forest are good places for them.

Federal Funding Obtained to Replace Zion National Park's Shuttle Fleet – And they’ll be electric! What a great way to keep the air smelling like nature rather than combustion fumes!

Rare Yellow Penguin Photographed for the First Time | Smart News Science | Smithsonian Magazine – What an unusual looking bird! It’s a king penguin on South Georgia Island with leucism, a condition where melanin is only partially lost and some parts of the body retain color. In this case…the ability to produce the usual black pigment is missing.

New River Gorge is America's Newest National Park - News | Planetizen – This park is within ‘road trip’ distance from where we live….maybe a destination post-pandemic.

How we turned a golf course into a haven for rare newts, frogs and toads – Hopefully US golf courses are doing things like this too. I usually think of them as using a lot of chemicals and would not want to live near a golf course….but if they consciously made places for amphibians….it would mean that other creatures could survive in the space too. There is an Audubon International Certification program for golf courses but they don’t publish a list of course that are certified.

The Arctic Ocean might have been filled with freshwater during ice ages – Based on a geochemical study of sediments.

Filling a Day of Social Distance – 3/22/2020

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Trying macro photographs of spicebush and red maple. My original plan was to tromp through the backyard and into the woods…do the photography outdoors. But – it was colder and breezier than I anticipated so I cut a small spicebush branch and picked up a twig of red maple samaras that had blown off. The photography part of the project would be done inside.

I worked with the red maple samaras first. I used a jeweler’s loupe and my cell phone with the samara on my kitchen countertop…a small flash light supplementing the natural light coming from one side. I like the graceful ridges in the ‘wings.’

2020 03 s IMG_8548 (2) clip.jpg

Then I ‘got close’ with my Canon point-and-shoot camera….let its macro setting do it’s best. These are small immature samaras…about 1/4 inch.

2020 03 s IMG_8548 (1).jpg

The spice bush flowers are small too. I put the branch in a vase (with the sycamore branch). I might get to see its leaves unfurl too…after the flowers are done. I noticed an ant on the branch as I put it in the water. Can ants be pollinators?

I tried several approaches to photographing the small flowers. The ones below were done with the clip-on macro lens on my phone. The challenge is the shallow depth of field. These flowers are small but not flat!

Then I tried putting my Canon bridge camera on a tripod across the kitchen and using the zoom. It blurs the background and provides more depth…but the color is gone. Maybe I’ll put more light on the flowers and try again. The sycamore buds might benefit from the same photographic strategy. My husband gets into the action too – helping me with the more complicated set ups.

Catching up on the Cincinnati Zoo Home Safari videos:

Completing the Jackson Pollock segment of the In the Studio: Postwar Abstract Painting Coursera course. I’ve been doing one ‘week’ of the course every day and enjoying all of them – particularly the part about learning how they were made.

Re-assessing our investment strategy…making some changes. At first, we thought that maybe the social distancing strategy would work, and the economy would blip but recover soon. Not enough people are following the guidance – it says something very sad about us as a nation – and means that the pandemic with be more overwhelming. From an economic standpoint, it is more than a blip and deteriorating further. So we made some investment changes to stabilize rather than free fall…..continuing our social distancing…and hoping that the tests of potential therapeutic drugs work well enough to save lives and shorten the time people are in the hospital to recover. Both my husband and I fell of the wagon of limiting time spent following the coronavirus stories and statistics yesterday…back to limiting that activity today – no one needs a constant pounding of repeating bad news.

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.

Look at What the Coastal Storms Have Done to the Chesapeake Bay - AGU Blogosphere – We had high winds in our area a week ago and it was worse (even higher winds and more precipitation) north of us. Trees feel, power outages prevalent, and some rail cars fell from a bridge as they crossed the Susquehanna River. The suspended matter in the rivers around the Chesapeake Bay were dramatically high…and it moved fast (lots of difference between March 4 and March 5). Wow!

New Perspectives on Bogotá’s Architecture Thanks to Drone Photography – I liked the first picture the best: the building footprint and the rooftop gardens…the trees below.

Forecasting diseases one image at a time – National Geographic Blog – Los Alamos working on predictive models of disease outbreaks in populations suplementing traditional data sources (with lag times in data availability) with non-traditional sources that are available more quickly to enable more timely response to disease outbreaks.

Are flamingos returning to Florida? -- ScienceDaily – Florida had flamingos in the 1800s but by 1900 they had been eliminated (killed for their plumage). Since 1950 they have been increasing in numbers and this study indicates that they are not just escapees from captive flocks. Most are birds from the Caribbean or Mexico that have repopulated Florida.

Can You Ever Have Too Many Turkeys? – Cool Green Science – Turkeys in Oregon – not native to the area but thriving – and an experience with the citizen science project to count them.

The Pileated Woodpecker in Winter – Cool Green Science – We have some pileated woodpeckers that make their rounds in the forest behind our house. They are indeed easier to see in the winter time than any other time of the year.

Welcome to the Age of Climate Migration - Rolling Stone – People are already moving from areas that are flooding more frequently. This appears to be an early indicator of economic consequences for climate change denial.

The Strange and Magnificent Nudibranchs of the Cape – National Geographic Blog – Marine slugs look so different from life we are used to seeing…they could be from another planet…but they are here on earth. Enjoy the pictures in this blog post.

Low magnesium levels make vitamin D ineffective: Up to 50 percent of US population is magnesium deficient -- ScienceDaily – Yet another reason to eat those leafy greens…or take a magnesium supplement.

Recovery: Evicting Rabbits – Cool Green Science – Ridding some islands of non-native rabbits so native flora and fauna can recover (penguins, birds, lots of plants)…with the help of a Labrador retriever wearing rubber booties!
