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.

A looming 'demographic cliff': Fewer college students and ultimately fewer graduates – Universities are already experiencing declining enrollment. In the first half of last year, more than one college a week announced that it would close….and the projection is that the pace of college closings could accelerate. This does not bode well for the US economy.

Charging Ahead: Key Geographical Clusters for Electric Trucks – The realistic sequence looks like: The west coast of the US up to British Columbia and New York to Virginia will be the first wave of green charging corridors for trucks. Virginia to Florida and then Texas to California with be the second wave.  I am bummed that Missouri (where I live) is not positioning itself to be in the second tier which would facilitate a complete cross county route.

Severe Cold Spells May Persist Because of Warming, Not in Spite of It – Evidently, we have a weaker, more meandering jet stream that allows frigid air to reach further south because the Arctic is heating up and there is not as much difference between the Arctic and warmer air to the south.

A Quarry Worker Felt Strange Bumps While Digging. They Turned Out to Be the Largest Dinosaur Trackway in the U.K. – I remember going to see the dinosaur tracks at Glen Rose, Texas. Somehow the huge tracks make it easier to internalize how big these animals were!

U.S. Surgeon General offers 'parting prescription' to heal America's division – Thought provoking.

Seven key climate and nature moments to look out for in 2025 - Big moments in 2025 that could shift the dial on climate and nature….while extreme weather continues.

Who built Europe’s first cities? Clues about the urban revolution emerge - Around 6,000 years ago, a group known as the Cucuteni–Trypillia culture developed egalitarian settlements north of the Black Sea and created the region’s earliest urban centers. Then, after two millennia, they vanished. Cucuteni–Trypillia has always stood out as something of an anomaly, because its settlements seemed to have been egalitarian societies that were devoid of social hierarchies. Their distinctive pottery was discovered almost simultaneously in two locations in the late nineteenth century: Romania (where the culture was named after a site in Cucuteni) and Ukraine (where the same culture was named Trypillia, also after a community where artefacts were found). The group made pots, hunted and gathered, farmed, raised cattle and lived in settlements where all the houses were the same size. People ate legumes and cereals grown on the rich soils of Ukraine, which were well manured by cattle. Livestock animals were also eaten, although isotope analysis of rare human remains shows that meat made up only roughly 10% of people’s diets. Despite the organized urban design of Cucuteni–Trypillia megasites, there were no palaces, no grand temples, no signs of centralized administration and no rich or poor houses.

Looking Back on Geological Activity in Yellowstone During 2024 - Hydrothermal explosion in Norris Geyser Basin in April, July explosion of Black Diamond Pool at Biscuit Basin, Economic Geyser(in Upper Geyser Basin) experienced a series of eruptions for the first time since 1999, Abyss Pool began to heat up and overflow/its color changed from dark and somewhat murky to a deep blue as the summer progressed, Steamboat Geyser continued to be active although with many fewer eruptions than in previous years…but the year was seismically calm!

Citizen science reveals that Jupiter's colorful clouds are not made of ammonia ice - The abundance of ammonia and cloud-top pressure in Jupiter's atmosphere can be mapped using commercially available telescopes and a few specially colored filters and the instrumentation/analysis showed that the clouds reside too deeply within Jupiter's warm atmosphere to be consistent with the clouds being ammonia ice.

Photographer Highlights the Importance of Monarch Butterfly Conservation Through Stunning Images – Photographs from Jaime Rojo. The monarch butterfly isn’t just a pretty sight—it’s an essential pollinator that keeps our planet healthy. But in the last 40 years, their population has dropped by a staggering 90%, leaving them on the brink of extinction.

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

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

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

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

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

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

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

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

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

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

BBC - Future - What happens when we run out of food? – Even in the US, nearly 12% of households re classed as being food insecure; more than 6.5 million children go without adequate food. And the whole food system can be disrupted very easily by war and very bad government all around the world.

Refugee women have healthier pregnancies than US women -- why? An unhealthy US culture: For African refugee women, acculturation may negatively impact health -- ScienceDaily – I was surprised that the researchers did not explore the idea that maybe the value of early pre-natal care is overrated for people that are generally healthy when they get pregnant since the refugee women tended to not start pre-natal care until their 2nd trimester.

Top 25 Wild Bird Photographs of the Week: Migration – National Geographic Society  - Birds are migrating through our area…we’re seeing more robins…and the juncos will leave soon to go further north. These pictures feature birds from around the world…that are migrating.

Hospital disinfectants should be regulated like antibiotics new study suggests – It’s not just antibiotics that drive antimicrobial resistance…it’s disinfectants (particularly in hospitals) too.

BBC - Future - The unexpected magic of mushrooms – New items made from fungus...replacing some kinds of plastics. It’s good that fungi are so plentiful on the planet – exceeding the biomass of all animals.

An Island Apart – Acadia National Park’s Isle ad Haut. A very different experience from Mount Desert Island

Beautiful cherry blossoms photos – Our cherry tree is in bloom right now. I guess cherry trees are enjoyed around the world very year about this time. There is a picture of the cherry trees around the tidal basin in Washington DC included in the pictures.

Green tea cuts obesity, health risks in mice: Follow-up study in people underway -- ScienceDaily – More research needed…. but I am enjoying green tea already (my favorite is a blend with mint).

A Mysterious Disease Is Killing Beech Trees | The Scientist Magazine® - Beech Leaf Disease…first spotted in Ohio in 2012 and expanding since then. It appears to be an infectious disease but the causal agent hasn’t been determined and there is no treatment yet. We have a lot of beech trees in Maryland’s forests. We lost the hemlocks and ashes….and years before the chestnuts. Each loss changes the forest.

The microbes that help make you and me and  BBC - What we do and don’t know about gut health and  Is it worth taking probiotics after antibiotics?  and How dirty air could be affecting our gut health and How to eat your way to a healthy gut – A series from BBC- Future.

New wisdom about high cholesterol treatment for adults aged 80 and older -- ScienceDaily – So many of the medical guidelines were developed with trials including younger people…and the assumption was made that it would be the same for older people. But now more people are living past 80 and it’s becoming clearer that it is not always the case.

See what your ZIP code says about you using Esri's ZIP lookup tool - Business Insider – The link is at the bottom of the article. I looked at places I am familiar with and it seemed about right. This would be an interesting tool to use if you were moving to a new area…provide a different perspective to your home search.

The Hidden Environmental Toll of Mining the World’s Sand - Yale E360 – Sand is needed for concrete…and a lot of building going on in the world. The problem of extreme mining in rivers and estuaries is increasing.

BBC - Future - The natural products that could replace plastic – Can any of these happen fast enough to stop – or even reduce - the flow of plastics into our rivers and oceans and landfills?
