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!

Illustrations in Children's Books - Soviet Union 1980s

/

Internet Archive has quite a collection of books for children published in the Soviet Union for export during the 1980s. I was very familiar with books for children published in the US during the same time because I was reading a lot of them with my young daughter in the early 1990s. The illustrations are the big draw – as the sample images from the books I browsed last January show. They are often colorful…sometimes artsy or whimsical…sometimes realistic. Enjoy browsing some children’s books!

In This Storied Egyptian City, Rising Seas are Causing Buildings to Crumble – Alexandria, Egypt. Since 2001, 290 building have collapsed as the rising water table weakens soil and erodes foundations. There are other historic coastal cities with the same problem.

Astronomers Discover 128 New Moons Orbiting Saturn, Cementing the Planet’s Title of ‘Moon King’ – The total number of moons of Saturn is now 274….almost twice as many as all the rest of the moons in our solar system combined.

Microplastics could be fueling antibiotic resistance - Microplastics -- tiny shards of plastic debris -- are all over the planet. They have made their way up food chains, accumulated in oceans, clustered in clouds and on mountains, and been found inside our bodies at alarming rates. Scientists have been racing to uncover the unforeseen impacts of so much plastic in and around us. One recent discovery: bacteria exposed to microplastics became resistant to multiple types of antibiotics commonly used to treat infections. They say this is especially concerning for people in high-density, impoverished areas like refugee settlements, where discarded plastic piles up and bacterial infections spread easily.

How the Development of the Camera Changed Our World - From glass plates to paper prints to digital photograph imaging, the photo revolution's intention remains the same—to immortalize our world.

Alphonse Mucha Helped Define Art Nouveau. A New Show Explores His Lasting Influence – Mucha was undeniably revered in his day, when his posters and advertisements were widely disseminated. His posters lined the streets, and his illustrations graced the covers of major magazines. And to feed the public demand for his work, Mucha even produced smaller posters printed in publications, allowing people to bring his ornately detailed lithographs home without having to rely on the luck of finding one in the wild. The special exhibit will be at the Nelson-Atkins Museum of Art, 4525 Oak Street, Kansas City, Missouri, April 11–August 30, 2026….maybe I will plan a road trip for next spring!

'You look up and see light coming through': The divers venturing under the ice in the name of science - In a remote corner of Lapland, northern Finland…a lake with 28 in. layer of ice with a hole cut in it. Divers are tethered to the surface using a safety rope, with a handler on the surface communicating with the diver via rope signals. The training here on the frozen lake is practice for work that will be done out on the sea ice of the Arctic and Antarctic, where there are added dangers – large seals sometimes gather at the dive holes, preventing divers from leaving the water. In 2017, Alf Norkko, a professor of marine research at the University of Helsinki, and his team discovered big changes on the seafloor under Antarctic sea ice since their previous diving expedition in the same area in 2009.  "There was a remarkable increase in the abundance of life," he says. Norkko says that he and his fellow scientists are so dedicated to this work because they are aware of the urgency of climate change. At present, there is a race afoot to understand it, and to respond to it.

Grave of Roman Twins Excavated in Croatia – Twins that died between birth and 2 months…placed face to face. Suffered malnutrition before birth. Infant mortality was as high as 30% in Roman societies.

Particulate matter levels in air exceed WHO limits in majority of world's big cities - Fewer than one in five global cities met World Health Organization air pollution standards (for PM2.5) in 2024 with Central and South Asia accounting for the nine most polluted metropolitan areas on Earth. Los Angeles and Ontario, California are the most polluted in the US.  Mayaguez, Puerto Rico had the cleanest air of any metro area around the world. Man-made activities such as fossil fuel burning for transportation, generating electricity and domestic heating, industrial processes, fireworks and smoking were the largest sources of pollutant PM2.5, but that natural sources including wildfires, dust, pollen and dirt also contributed to particulate loads in the air.

China’s First Domestic Cats Took the Silk Road 1,400 Years Ago, New Study Finds - The Tang Dynasty (618–907 C.E.), from which the oldest cat in the study hails, saw peak activity along the legendary trade network, which boosted the exchange of goods and ideas between China, India, and Persia. It’s not improbable that merchants from the West could have carried cats on their journey to East Asia.

Can Toxic Mining Waste Help Remove CO2 from the Atmosphere? - On the coast of Newfoundland, waste from a shuttered asbestos mine has been a troubling source of contamination for decades. Now, a company plans to process the waste to draw CO2 from the air — one of several projects worldwide that aim to turn this liability into an asset. A 2022 report by the Lawrence Livermore National Laboratory estimated that existing asbestos tailings in Canada and the United States could remove up to 750 million tons of CO2 in total — while also removing an environmental health hazard.

The Craftsman (magazine)

/

I browsed 24 months of The Craftsman magazine from the early 1900s back in December. They are available from The University of Wisconsin-Madison digital library. They are a way to understand the way people were living at the time – a time when my grandparents were born. Some of the styles look “heavy” by today’s standards…but they were built to last from daily use. Some would still fit into a home today. Click on any of the sample images below to see a larger version…and use the links to browse the whole magazine.

The Largest Harbor in Ancient Greece Is Centuries Older Than We Thought - A discovery of lead pollution and 5 lumps of brown coals were carbon dated to the days of the Bronze Age.

When This Brilliant Author Died, She Left Behind a Legacy of Grief, Haunting Poetry and Surprising Resilience – I remember reading Silvia Plath books as a teenager.

Maple seeds’ unique spinning motion allows them to travel far even in the rain, a new study shows – Autorotation keeps the seeds in the air for longer, so they travel farther. The researchers studied how raindrops that hit the seeds reduce the time they are in the air. The next part of the study will look at rolling samaras (from tulip poplar and ash trees).

Rare Footage Shows Baby Polar Bears Emerging from Their Den in the Arctic - At birth, polar bears are blind, nearly hairless and weigh just over a pound—about the same as a loaf of bread. But they spend their first few months snuggled inside a snowy den, fattening up on their mother’s milk. By the time they emerge in the spring, the cubs are covered in fluffy white fur and weigh 22 to 26 pounds. Scientists have managed to capture rare footage of a polar bear mother and her cubs leaving their den in the Arctic for the first time.

Summer Heat Wave in South America - In February 2025, an area of high pressure parked over the southern Atlantic Ocean, causing temperatures to soar in parts of South America. As of February 27, Argentina noted that six provinces were under a red-level (very dangerous) alert for extreme heat.

The world's strongest ocean current should be getting faster – instead, it is at risk of failing – The Antarctic Circumpolar Current - five times stronger than the Gulf Stream and more than 100 times stronger than the Amazon River. Fresh, cool water from melting Antarctic ice is diluting the salty water of the ocean, potentially disrupting the vital ocean current.

More Than 1,500 Sandhill Cranes Killed by Bird Flu in Indiana - In recent weeks, biologists with the Indiana Department of Natural Resources have counted hundreds of dead sandhill cranes statewide. At least 500 of the birds were found dead in Jackson County, in the south-central part of the state, in early January. So far, no sick or dead cranes have been reported in Nebraska.

Inside the Clear Waters of England’s Ancient Chalk Streams - A globally rare type of waterway found almost exclusively in England—these rivers’ specific features both create rare biodiverse habitats and make them uniquely vulnerable. Burbling up from aquifers formed in chalk layers that date back to the Cretaceous Period, these rivers exist only where chalk sits close to the Earth’s surface. That’s why of the 200-odd identified chalk streams in the world, nearly all of them are found in England, where 66 million years ago a shallow seabed collected the skeletons of aquatic creatures—the makings of chalk. Ideal habitat for trout and Atlantic salmon.

How our lungs back up the bone marrow to make our blood - Researchers at UCSF found hematopoietic stem cells (HSCs) in human lung tissue that make red blood cells, as well as megakaryocytes, which produce the platelets that form blood clots.

Gold Jewelry Found at Karnak Temple - Karnak was the largest and one of the most important religious sites in ancient Egypt. An Egyptian-French team was investigating the northwest sector of the precinct when they uncovered a ceramic vessel that contained a collection of gold jewelry and statuettes dating to the 26th Dynasty (664–526 b.c.). One of the statuettes depicts the Theban triad of gods: Amun, his wife Mut, and their son Khonsu. Archaeologists also discovered several mudbrick buildings dating to the same era that were likely used as workshops or storage facilities connected to the Karnak temples.

Francois Le Vaillant’s Birds

/

The week’s eBook pick is the six volumes of Francois Le Valllant’s Histoire naturelle des oiseaux d'Afrique published between 1796 and 1808 and available from Internet Archive. The illustrations of birds were created from his collection of skins preserved with arsenic soap that were stuffed and mounted in near lifelike positions. He was one of the first to use color plates in his books about birds and was a keen observer of bird behavior. Enjoy the sample images….and browsing the whole volumes!

Whorls of White off Greenland – A satellite image (from the Terra satellite), captured on February 24, 2025, shows the southern part of Greenland, from its snow-topped ice sheet and glaciers to the sea ice swirling along its coasts. When this image was acquired, the sea ice extent along Greenland’s East Coast was about average. However, Arctic-wide, sea ice in late February was exceptionally low for the time of year due to a warm winter.

The baby boom in seven charts - The US baby boom is typically defined as the time period between 1946 and 1964. But – it appears that the increase in birth rate began earlier…in the late 1930s. And it happened in many countries at the same time. This common trend across many countries suggests that the baby boom was driven by shared societal shifts rather than isolated national circumstances. The baby boom was also surprising because it happened alongside rising levels of women’s education and workforce participation — changes that now often coincide with falling birth rates.

Cheap Chinese Panels Sparking a Solar Boom in the Global South - A surge in solar installations in parts of the developing world. The glut of cheap solar means poorer countries can speed their shift away from fossil fuels while shoring up their supply of energy.

Following Frogs into the Flames – The tree frogs are using the trees all the way up to 40 feet, up to the crown of the tree, as a safe place during fires, and also for several weeks after the fire, when the ground is still somewhat inhospitable.

Brewing tea removes lead from water – Brewing black tea in cellulose tea bags works best for removing lead…longer steeping removes more.

Where California’s Land Is Sinking and Rising – Analysis of vertical land motion between 2015 and 2023. Areas of sinking land in coastal California cities and in parts of the Central Valley are caused by factors like soil compaction, erosion, and groundwater withdrawal.

Oldest Section of China’s Great Wall Uncovered - The recent excavations occurred around what is known as the Qi Wall, which was already considered to be the oldest in existence. New dating, however, suggests that the wall’s construction originates to the late Western Zhou Dynasty (ca. 1050–771 BC) and the Spring and Autumn Period (770–ca. 475 BC), making it 300 years older than previously thought.

What happens when a diet targets ultra-processed foods? - The findings suggest that people can reduce their ultra-processed food intake, if given the proper tools, and that they will be enthusiastic about interventions designed for this purpose. The results also suggest that reducing UPF intake will lead to meaningful health improvements -- such as weight loss and better mood -- in as short as eight weeks.

Glass fertilizer beads could be a sustained nutrient delivery system - Excessive and inefficient use of agricultural fertilizers can present an environmental threat, contaminating waterways and generating greenhouse gases such as nitrous oxide. Now, researchers have addressed those challenges with glass fertilizer beads. The beads control nutrient release….releasing fertilizer over a longer time period.

Historic Frank Lloyd Wright Home Gifted to Chicago University – The last remaining example of Wright’s prairie-style designs. When the Bach residence was completed in 1915, it boasted walnut furnishings throughout and a clear view of Lake Michigan from its rear porch.

Scientists Investigate Smell of Egyptian Mummies – A systematic study of the smells of 9 Ancient Egyptian mummified bodies. Odors are from pine, cedar, juniper, frankincense and myrrh.

'Healthy' vitamin B12 levels not enough to ward off neuro decline – The conclusion: “we need to invest in more research about the underlying biology of B12 insufficiency, since it may be a preventable cause of cognitive decline.”

Rethinking Fire-Resistant Landscaping: Which Trees Should We Plant? – After the recent wildfires across Southern California - Experts recommend replacing highly flammable trees with fire-resistant alternatives such as oak, sycamore, toyon, lemonade berry, and lilac. While the idea of removing iconic palm trees may be met with resistance, fire safety advocates argue that proactive changes in landscaping are necessary to adapt to the increasing wildfire risks in California.

Floods Swamp Tennessee – Satellite image from February 17 of the flooding after the February 15-16 storm. The area of western Kentucky to the north had more severe flooding….but clouds prevented a similar image on the 17th.

Learn COVID pandemic lessons — before it’s too late - “The science will deliver if we have a new emerging infectious disease,” says Joanne Liu, a pediatric emergency-medicine specialist at McGill University in Montreal, Canada, and a former international president of the medical-aid organization Médecins Sans Frontières (also known as Doctors Without Borders). “I think it will be the people who aren’t going to deliver…..None of us thought about the case scenario in which we would have leaders and a large part of the population that do not believe in science.” Yet that scenario is here. It means that researchers in public health and infectious diseases must work closely with social scientists who have been studying how another disease — misinformation — spreads and how best to counter it.

In many countries, people breathe the cleanest air in centuries. What can the rest of the world learn from this? – Lots of graphs….focused on sulfur dioxide and nitrogen oxide emissions….and the relationship to coal and catalytic converters.

The Science of Snakehead Slime - One of this fish’s most reported habits is its ability to move about on land. The answer, according to new research, may lie at least in part with another of the snakehead’s infamous features: its slime.

Wide-Eyed Fly Wins the 2024 Royal Entomological Society Photography Competition – Macro photography of insects…great work my amateur photographers. My favorite was the ladybird larva feeding on a colony of aphids.

How much protein do you really need to get strong? – A concerning take away: In 2018, a nonprofit group called the Clean Label Project, based in Broomfield, Colorado, released a report about toxins in popular brands of protein powders in the US. Researchers screened 134 products for 130 types of toxins and found that many protein powders contained heavy metals (lead, arsenic, cadmium and mercury), bisphenol-A (or BPA, which is used to manufacture plastic), pesticides, or other contaminants with links to cancer and other health conditions. Interestingly, one certified "organic" product had twice the contaminants of non-certified ones. Plant-based protein powders were the most contaminated, while egg and whey-based powders were found to be the cleanest.

Dust from Car Brakes More Harmful than Exhaust – Brake dust evidently causes greater injury to lung cells than diesel exhaust. Brake pads on the market now include copper which can aggravate asthma when inhaled. Note: the shift to electric vehicles could curb pollution from brake pads. Most electric cars use regenerative braking that limits the need for conventional brake pads.

Victorian Decorative and Applied Arts

A Five-Pound Hunk of the World’s Oldest Known Synthesized Pigment Was Found in Nero’s Palace – Egyptian Blue. The pigment is a synthetic pigment produced by firing a mixture of silica, limestone and minerals containing copper and sodium carbonate at high temperatures. The Roman architect Vitruvius recorded the recipe in his treatise De Architectura in the first century B.C.E., reflecting how the color spread through the Mediterranean world. Archaeologists discover traces of Egyptian blue that are all but imperceptible to the human eye. For instance, with the help of microscopes and luminescent imaging, researchers at the British Museum discovered that Egyptian blue once adorned the Parthenon marbles.

See the First Stunning Images Taken by the Blue Ghost Lunar Lander on Its ‘Scenic Route’ to the Moon – It still has a few months before reaching the moon….lots of Blue Marble views.

Changing cholesterol over time tied to risk of dementia – Interesting result. I wondered if cholesterol fluctuation is more concerning that merely being high….that there in an underlying reason for the fluctuations that indicates a problem that is not being directly addressed by the medications that generally are trying to lower cholesterol.

Astronomers have spied an asteroid that may be heading for Earth. Here’s what we know so far – On December 22, 2032,  the asteroid 2024 Y04 might collide with Earth. It was first detected on December 27, 2024 and will continue to be observed until it will be lost to our telescopes until we will see it again in 2028 and refine what we know….be able know for sure whether there will be a collision and where on earth the collision will be. In just the past few years, we have discovered 11 asteroids before they hit our planet. In each case, we have predicted where they would hit, and watched the results. We have also, in recent years, demonstrated a growing capacity to deflect potentially threatening asteroids.

An Arctic 'beyond recognition' by 2100 - Under 2.7 degrees Celsius of warming, the Arctic region is likely to experience the following effects:

  • Virtually every day of the year will have air temperatures exceeding pre-industrial temperature extremes.

  • The Arctic Ocean will be free of sea ice for several months each summer.

  • The area of the Greenland Ice Sheet that experiences more than a month of surface temperatures above 0 degrees Celsius will quadruple compared with pre-industrial conditions, causing global sea levels to rise faster.

  • Surface-level permafrost will decrease by 50 percent of pre-industrial levels.

Study Highlights Challenges to The Electrification Of Homes In The US - Solar powered homes demonstrated impressive resilience during summer heat waves. However, they proved remarkably vulnerable during winter storms. In fact, fully electrified homes were nearly three times more vulnerable to winter outages, compared to those drawing power from mixed energy sources. The integration of distributed energy resources such as solar and battery storage has emerged as a critical factor in household resilience.

Sky skimmers: The race to fly satellites at the lowest orbits yet – A handful of pioneering companies have begun work on designs for satellites that may be able to orbit the planet at unusually low altitudes while simultaneously harvesting air and using it to make propellant – literally on the fly. This new generation of orbiters could enable ultra-high-definition surveillance of activities on the ground, or superfast satellite-based communications. The race is on. (I wondered if the US activities mentioned in the post are going to survive budget cuts.)

Low-level traffic air pollution linked to liver damage and fatty liver disease - When we inhale air pollution, the very tiny particles known as PM2.5 enter the bloodstream through the lungs. The liver, which filters toxins from the blood, then accumulates these substances, which can include heavy metals such as arsenic, lead, nickel and zinc. The study authors suggest avoiding peak hour traffic, taking less congested routes when walking or cycling or consider wearing a mask, and keeping car windows closed with air recirculation mode on while driving in heavy traffic.

Hitting Its Stride or Hitting a Wall? South Texas at a Watershed Moment - Between extreme heat, flooding, drought, and the vagaries of politics and international trade, there is a growing fear that the Valley’s boom times could come to a grinding halt — or worse, that the region will experience the same type of climate-related exodus that has pushed many of today’s current immigrants to its doorstep. An even bigger question is whether the region has become a harbinger of mounting international tensions over shrinking resources that are expected to play out with more frequency in coming years.

Searching the entire sky for the secrets to our universe - As soon as the end of February, NASA and the Jet Propulsion Laboratory will launch a new telescope into orbit around the Earth. SPHEREx will join the ranks of other space telescopes, filling in a crucial gap by detecting infrared light with wavelengths too long to see with the naked eye. It's an important addition because no single instrument can fully perceive the universe and its contents. Infrared can also be used to detect the unique fingerprints of particular molecules in the universe, including the basic components of life — water and organic materials frozen in the ices of interstellar dust clouds where stars are born.

Images of the Middle East in the 1830s

The New York Public Library Digital Collections has the lithographs from Léon de Laborde’s Journey through Arabia Petraea, to Mount Sinai, and the excavated city of Petra available online. There are 60+ plates to browse! I liked that almost all of them include people…providing scale to the monuments and landscapes depicted. How many of those places still exist…how many are rubble now because of the many wars that have happened in the years since 1830?

Archaeologists Unearth Ancient Footprints of People Fleeing Vesuvius Eruption – From 2,000 years before the eruption of the same mountain destroyed Pompeii.

Oldest Known Evidence of Lead Pollution Found in Ancient Greece - Scientists identified traces of lead contamination that date back more than 5,000 years by analyzing sediment cores from Greece’s mainland and the Aegean Sea. The lead emissions followed the development of smelting technologies, which produced metals like silver. A sharp increase occurred about 2,150 years ago, which coincides with the Roman conquest of the Greek peninsula in around 146 B.C.E. and drove demand for silver higher for currency and lead for construction/tableware.

Half a degree further rise in global warming will triple area of Earth too hot for humans - The amount of landmass on our planet that would be too hot for even healthy young humans (18-60-year-olds) to keep a safe core body temperature will approximately triple (to six percent) -- an area almost the size of the US -- if global warming reaches 2°C above the preindustrial average. Last year was the first calendar year with a global mean temperature of more than 1.5°C above the pre-industrial average, and at current rates of warming, 2°C could be reached by mid to late century.

How Tearing Down Small Dams Is Helping Restore Northeast Rivers - Restoring natural flows, improving habitat for aquatic life, and reopening thousands of river miles to migratory fish, from shad to American eels. I was aware of several dams being removed on the Patapsco River in Maryland before we moved to Missouri.

Yellowstone National Park: Where Geology Is on Display Nearly Everywhere – Maybe we should plan a trip Yellowstone; it’s been 20 years since we were there before. It would be a great capstone to the geology course I am taking this semester.

Restoring Appalachian Forests After a Legacy of Mining – It isn’t about returning land to some “pristine” past. It’s about creating a resilient future, a forest where native plants and wildlife can thrive. When mining companies left, following state and federal guidelines, they often replanted their sites with plants that would mainly reduce erosion. That sounds good in theory, but many of those plants were invasives like autumn olive and sericea lespedeza. Trees that thrived on such sites tended to be adaptable species. These former mine lands offered little habitat to wildlife and little value to carbon storage. The first step is to control the invasives, through mechanical clearing. And then bulldozers rip up the soil. Next came the planting, accomplished by crews hand planting trees on the site, a diverse mix of trees, grasses and wildflowers. Some native plants, their dormant seeds “freed” from compacted soil, return on their own. Wildlife begins using restored areas almost as soon as they’re established. It benefits popular game species like white-tailed deer, turkey and elk.

Vertical Farms Grow in Office Buildings - Vertical farming can make use of vacant office space and grow food where agricultural land might be scarce. One drawback: energy use. Vertical farms need a lot of electricity to run lighting and ventilation systems, smart sensors and automated harvesting technologies….so maybe clad the office buildings in solar panels and put batteries in the basement?

Not so snowy Alaska - A spell of unseasonably warm weather in winter 2024–2025 has meant less snow for parts of the normally frozen state of Alaska.  Images from the Moderate Resolution Image Spectroradiometer on NASA’s Terra and Aqua satellites.

Colossal squid: The eerie ambassador from the abyss – The biggest invertebrate on Earth. One of the creatures was captured alive (briefly) off New Zealand 100 years ago. The first clues of their existence in the deep ocean was from occasional remains found in the bellies of whales that hunt them. It has swiveling hooks on its arms and a beak made out of protein similar to human hair and fingernails. The eyes are the largest eyes found in any animal yet discovered.

The Breathtaking Hermitage Museum, Filled with Treasures Like the Kolyvan Vase and the Peacock Clock, First Opened to the Public on This Day in 1852 – There are 6 main buildings and it has about 50 cats that keep it free of mice! It is the second largest museum in the world (the Louvre is the largest).

Ippolito Rosellini’s Ancient Egypt

/

The New York Public Library Digital Collections includes the illustrations of Ippolito Rossillini’s I Monumenti dell'Egitto e della Nubia. It was published between 1832 and 1844 documenting the Franco-Tuscan expedition to Egypt (1828-1829) and after the death of Jean-Francois Champollion (leader of the expedition) in 1832.

There are over 400 plates to enjoy – some simple drawings and some with color. I picked 6 of the color images as samples.

Frank Lloyd Wright’s Only Skyscraper to Be Sold for $1.4 Million After Legal Saga – Hopefully the power gets turned back on right away and the conservation of the building starts.

Under Colonial-Era Barracks Floorboards in Australia – Peanut shells, peach pits, citrus peel, hazelnuts….hiding the remains of treats from the authorities.

Experts Are Unraveling the Mysteries of This Breathtaking 2,000-Year-Old Mosaic Depicting Alexander the Great in Battle – The mosaic comes from the ruins of Pompeii and was discovered in 1831. It is housed in the National Archaeological Museum of Naples. Conservation work started in 2020. The mosaics tesserae rocks could have come from Italy, Greece, the Iberian Peninsula and Tunisia.

Mt. Washington Cog Railway Goes Electric! - Engineering students from the University of New Hampshire are working alongside the Mt. Washington rail staff to develop an all-electric locomotive, with help from robotic welding systems. It will be the world’s first entirely battery-powered mountain-climbing electric vehicle.

As Oceans Warm, Predators Are Falling Out of Sync with Their Prey - Warning signs are beginning to be observed in marine ecosystems planetwide, from herring and zooplankton in the North Sea, to sardines and bottlenosed dolphins in the Southern Ocean, to — along with striped bass — baleen whales and menhaden in the northwest Atlantic.

Meet the Channel-billed Cuckoo, the World’s Largest Brood Parasite - They’re the size of a raptor, with broad wings, a long, trailing tail, and a honking great bill reminiscent of hornbills or toucanets. Their plumage is a light grey, with thick black and white banding on the tail feathers. And their eyes: large, beady, blood-red, surrounded by a strawberry-colored ring of bare skin.   

Noise as a Public Health Hazard - Cities in Europe and the United States are starting to map noise levels to understand where dangerous sound levels exist and how to better protect people living and working nearby.

Atop the Oregon Cascades, team finds a huge, buried aquifer - Scientists have mapped the amount of water stored beneath volcanic rocks at the crest of the central Oregon Cascades and found an aquifer many times larger than previously estimated -- at least 81 cubic kilometers. The finding has implications for the way scientists and policymakers think about water in the region -- an increasingly urgent issue across the Western United States as climate change reduces snowpack, intensifies drought and strains limited resources.

Carbon Dioxide Levels Rose by a Record Amount Last Year - Last year saw the biggest one-year jump on record for the past 60 years, with carbon dioxide levels rising by 3.58 parts per million. Increasingly severe heat and drought mean that trees and grasses are drawing down less carbon dioxide than in the past, while desiccated soils are also releasing more carbon back into the atmosphere. Conditions were particularly poor last year owing to a very warm El Niño which fueled hotter, drier weather across much of the tropics. The forecast is for a smaller jump in carbon dioxide levels in the coming year because the Pacific is now in the La Niña phase.

Floods linked to rise in US deaths from several major causes - Over the last 20 years, large floods were associated with up to 24.9 percent higher death rates from major mortality causes in the U.S. compared to normal conditions. A new study demonstrates the sweeping and hidden effects of floods --including floods unrelated to hurricanes, such as those due to heavy rain, snowmelt, or ice jams.

Warmer, Greener Arctic Becoming a Source of Heat-Trapping Gas - Roughly half of the region is growing greener, but only 12% of those greener areas are actually taking up more carbon.

More Than 100 Died When the S.S. Valencia Wrecked in the ‘Graveyard of the Pacific’ - Not long before midnight on a night with poor visibility in 1906, the Valencia struck a rocky reef off the west coast of Vancouver Island. The captain ordered the ship run aground, but it caught on rocks less than 400 feet from shore….and sank over the next 40 hours. The rough seas made it difficult of lifeboats and many capsized. 136 people died, 37 survived. Weather, waves, swift currents and a shifting sandbar made the area particularly hazardous, even for experienced captains. Lessons learned from the wreck of the Valencia are its most lasting legacy.

Menopause research is globally underfunded. It’s time to change that - The overwhelming majority of studies in the field of ageing do not consider menopause…and yet half the population will experience it. The disruptive nature of menopause and its health impacts have been known perhaps for millennia and should have been a topic for health funders for a long time. It is never too late to start.

How To: Go Snow Day Birding (with Merlin) – A good idea for a snowy day (maybe not if the temp is in the teens or single digits though).

Fighting Forest Pests With AI: A Hemlock Success Story – Fighting the hemlock woolly adelgid…increasing the odds of saving some trees. It’s too late for the ones behind where I used to live in Maryland. They succumbed to the pest years ago.

Incredible Winners of the 2024 Ocean Art Underwater Photography Contest – I like the ones that are good documentation of a species…and art at the same time.

In the Northeast, 50% of adult ticks carry Lyme disease carrying bacteria – Not good for public health

Inca Tunnel System Identified Under Cuzco – More than a mile of tunnels that reflect the streets and walkways in the Inca capital.

Archaeologists in Pompeii Discover Private Spa Where Dozens of Guests Bathed in Luxury 2,000 Years Ago – Found in a lavish home…big enough to host 30 people. Three rooms: calidarium (hot water), tepidarium (rub oil on skin and immerse in warm water), and apodyteriaum (changing room with mosaic floor). The spa was connected to a banquet room decorated with elaborate frescoes depicting characters from the Trojan war.

New study identifies how blood vessel dysfunction can worsen chronic disease - Specialized cells surrounding small blood vessels, known as perivascular cells, contribute to blood vessel dysfunction in aging, chronic diseases such as cancer, diabetes and fibrosis.

Bird Images from Ancient Egypt

/

Jean-François Champollion is best known as a founding figure of Egyptology – primarily known as the primary decipherer of Egyptian hieroglyphics. He died in 1831 (at 41 years old) and the book I am featuring as the ‘book of the week’ was published posthumously by his brother. There are many illustrations in the book and the version available from the New York Public Library Digital Collections includes many illustrations in color. It is well worth browsing.

Monuments de l'Égypte et de la Nubie

My favorite images in the book are of birds from the tomb of Khnumhotep II at Beni Hasan. The notation in the book is: Béni-Hassan el-Qadim [Beni Hasan]. Peintures copiées dans les tombes de Névôthph et de Ménothph. Beni Hasan is famous for tombs with high quality paintings although many are in poor condition today; fortunately, several of them were well documented in the 1800s…as the bird images shown in this book.

Learning about Missouri Geology – January 2025

/

After the field trip to the Joplin History and Mineral Museum, I set a goal for myself to learn more about Missouri Geology in 2025…hopefully make field trips throughout the state. January was a month to do some research. I already had two books (Roadside Geology of Missouri by Charles G. Spencer and Geology of Missouri State Parks by Max W. Reams and Carol A. Reams) that I was reading – already referencing to plan the coming months.

I found that my local library had several other books. They were older and out of print. Two of them could only be used in the library. Sitting in a comfy chair in the library browsing them was an hour well spent. I took pictures of the cover/title page and some of the maps/pictures/tables – realizing that this was a better option than the copier machine.

Missouri Geology by A.G. Unklesbay and Jerry D. Vineyard

Springs of Missouri by Jerry D. Vineyard and Gerald L. Feder

The third book was available for checkout so it was actually read: Gargoyle Country – The Inspiring Geology of Springfield & Greene County by Jerry D. Vineyard.

I also discovered a great overall Geology resource – a National Park Service website! It’s not specific to Missouri though.

America’s Geologic Legacy

My husband and I signed up for two birding field trips this winter that are in very different areas of the state. They will both double as geology field trips! The first one is in a prairie area of Missouri and the second is far north in the state in an are that was glaciated in the last Ice Age. I’ll take my reference books and look at roadcuts along the way (since my husband will be driving)….and geologic features while we are out of the car.

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 Will Climate Change Affect the Spread of Invasive Species? - The silver lining of knowing humans are still one of the main drivers of invasive species spread, is that humans can also curb invasive species spread. We can plant native plants in our yards and gardens instead of ornamentals from other states and countries. We can clean our boots, shoes, fishing waders and boats when we travel from one area to another, and we can stop releasing unwanted pets into local parks, ponds or creeks.

Kangaroo species went extinct in the Pleistocene - Nearly two dozen kangaroo species vanished in the Pleistocene. If things get warm enough, dry enough, kangaroos today are going to have a tough time making it, regardless of whether they're mixed feeders.

Medieval Crowns and Scepters Discovered Hidden Inside the Walls of a Crypt Beneath a Lithuanian Cathedral – It had been hidden for 85 years—since it was stowed for safekeeping beneath the Vilnius Cathedral in southeastern Lithuania - put there at the outbreak of World War II in 1939.

Your work habits may be threatening your sleep - Sedentary workers experience a 37% increase in insomnia-like symptoms. Employees working nontraditional schedules experience a 66% greater risk of needing 'catch-up sleep.' It’s more about how jobs are structured and staffed than individual ‘habits.’

Bold Parakeet Biting a Lizard’s Tail Wins SINWP Bird Photographer of the Year Contest – Lots of great photos!

Renewables Supplied Two-Thirds of Germany’s Power Last Year - In Germany the solar buildout continues to surpass government targets, with solar now amounting to 14 percent of power generation. Wind remains the biggest source of clean electricity, accounting for 33 percent of generation, though new wind farms are being developed more slowly than planned. Along with new renewable power plants, Germany is seeing a growth in battery storage as homeowners install batteries alongside rooftop solar panels.

Why just two hours of exercise a week can be life-changing - One retrospective study of over 37,000 people found those who did their week's worth of physical activity over just one or two days had the same reduction in cardiovascular disease risk as those who did activity spread throughout the week.

Lead pollution likely caused widespread IQ declines in ancient Rome, new study finds - Scientists used Arctic ice core records to reconstruct historic atmospheric lead pollution in Ancient Rome and link exposure to cognitive declines. Ancient lead pollution stemmed largely from silver mining, whereby the lead-rich mineral galena was melted down to extract silver. For every ounce of silver obtained, this process produced thousands of ounces of lead -- much of which was released to the atmosphere. In the 20th century, lead pollution predominantly came from the emissions of vehicles burning leaded gasoline.

A Half Mile Underwater on Connecticut’s Eight Mile River - Designated a Wild and Scenic River. Black rock geology and tannin in the water take most of the light making visibility to a snorkeler limited.  Caddisfly larvae, mussels, Chinese snails (invasive, aquarium escapees), musk turtle, white sucker, common and spottail shiners, sea lamprey (a native here, unlike in the Great Lakes), redbreast sunfish.

Pirates, princes and hostages: inside the mysterious life of the unnamed medieval princess of Cyprus – An example of how medieval women found ways to overcome the limitations placed on them…but not one with a ‘happy’ ending.

David Roberts’ Lithograph Prints from Egypt and Nubia

/

The New York Public Library Digital Collections has a book of prints created between 1846 and 1849 by Scottish artist David Roberts. The were evidently based on his sketches made during his travels to Egypt and Nubia between 1838-1840. The images were a success in Britain – predating the earliest photographs of the sites. This collection is well work a look! I’ve picked 4 samples…but there are many more online and easy to browse.

52 years

Another wedding anniversary…

January is the month I got married…52 years ago. There were patches of ice on the ground in much of Dallas on the day, but the roads were clear enough that our small ceremony and larger reception at my parents’ house went as planned.

Looking back at the years, I am a little surprised at how many of them there are! We were among the first of our friends to marry and we survived those early years even better than we expected…being in school for most of the first 10 years.

There are so many positive trends that made our marriage easier than most:

Our careers were enjoyable and well-paying --- more than keeping up with inflation (which was a challenge in the 1970s and 1980s).

Every move to a new home was a better house than the last.

Our daughter was born after 16 years of marriage and still brings joy to our lives.

Our medical expenses were never great (always well covered by insurance through our employers and, now, Medicare).

Travel was always within our budget (we now tend to stay in hotels rather than camp as we did in the early years) and has resulted in many new experiences.

The post-career years have been good (so far).

Of course, there were some choices that might not have been the best, but they didn’t have a long-term negative impact. My philosophy all along has been to live in a way that I will have few regrets….and it has served me well.
