Gleanings of the Week Ending January 20, 2024

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.

Just how big can a snowflake get? It depends on what you mean by 'snowflake' - A snow crystal with six-fold symmetry is the kind of snowflake you might cut out of folded paper with scissors. But the word "snowflake" also can refer to white puffballs that drift down from the sky, which are made of many individual snow crystals that have collided and gotten entangled.

Treating tuberculosis when antibiotics no longer work - Substances that have a dual effect against tuberculosis: They make the bacteria causing the disease less pathogenic for human immune cells and boost the activity of conventional antibiotics.

Planning a city that gets people moving – Lake Wales, Florida has a plan to create a built environment that promotes mobility through walking, cycling, e-biking, or other means of transportation beside automobiles. One way to do that is through proximity—to a park, multiuse pathway, protective bike lane, or walkable destination. Another is to ensure that the environment is pleasant for walking or using a bicycle.

The qualities that are more attractive than our looks - When it comes to finding the right match agreeableness accentuates the benefits of other parts of our personalities. It really could pay to be kind after all.

Archaeologists Uncover ‘Exceptional’ Ancient Mural Near Colosseum - Crafted of shells, a special volcanic stone called pozzolana, marble, colored glass, and Egyptian tiles found in the remains of a house from more than 2,000 years ago. Its intricate designs show weapons and instruments hanging alongside ships and tridents. Archaeologists think a wealthy Roman officer commissioned it after a military success. Whoever the owner was, he may not have stayed wealthy for long. Evidence suggests that his family fell out of favor when the Roman emperor Augustus came to power. The building and its contents were later buried and replaced with a grain store built directly on top of it.

A Lake Born out of an Earthquake – Earthquakes can fundamentally reshape the landscape, reroute rivers, and even form new lakes. Consider the northwest corner of Tennessee in the early 19th century. Between December 1811 and February 1812, three earthquakes with magnitudes greater than 7 occurred in the New Madrid seismic zone, which encompasses southeastern Missouri, northeastern Arkansas, and neighboring parts of Tennessee and Kentucky. The last of these quakes, on February 7, 1812, centered near New Madrid, Missouri, was especially notable: It temporarily rerouted the Mississippi River, permanently dammed the Reelfoot River, and directed water to fill in a low-lying area to form Reelfoot Lake. More than two centuries later, Reelfoot Lake remains a persistent feature on the Tennessee landscape. An image from Landsat 9 shows the area in late 2023. The area of lake and surrounding wetlands is a state park and national wildlife refuge.

Cats Prey on More Than 2,000 Different Species - Scientists have long known that free-ranging cats—those that spend unsupervised time outdoors—can affect biodiversity by hunting and eating insects, birds, reptiles and mammals. Researchers sifted through hundreds of previous studies, books and reports to put together a database of every animal cats have been recorded eating, as well as the location. In the end, their list featured 2,084 species, which includes 981 birds, 463 reptiles, 431 mammals, 119 insects and 57 amphibians, plus 33 additional species from other groups. Some of the creatures that made the list—including humans—are too large for cats to hunt but reflect their scavenging tendencies. Though the findings are useful, some scientists say they distract from a much larger threat to biodiversity: humans.

Autistic people experience loneliness far more acutely than neurotypical people -Small adjustments to lighting, acoustics, decor and wayfinding, among other sensory factors, can significantly reduce the burden on people with sensory processing differences and open up more social spaces to them.

Inhalable sensors could enable early lung cancer detection - The new diagnostic is based on nanosensors that can be delivered by an inhaler or a nebulizer. If the sensors encounter cancer-linked proteins in the lungs, they produce a signal that accumulates in the urine, where it can be detected with a simple paper test strip. It could replace expensive CT scans for lung cancer (and be more accurate…not as many false-positives).

This Photographer Captured One Image of Cambridge (England) Every Day for 13 Years - After 5,000 photos, Martin Bond has decided to conclude his project, which showcased the city’s mundane and extraordinary moments. “The best thing about street photography ... is that it is possible for the final viewer of a picture to see more than the original photographer—proof, if any were needed, that there is more going on in any moment than a single person can understand.”

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.

As the Mississippi Swerves, Can We Let Nature Regain Control? - After the lower Mississippi began pouring through and enlarging Neptune Pass in 2019, sediment began flowing into a sand-and-silt-starved Delta Bay. Now the Army Corps of Engineers — breaking with tradition — is considering letting at least part of the river have its way…..a change from always ‘filling the breach’ strategy of years past that has had positive economic impacts but caused environmental problems. According to the U.S. Geological Survey, since 1932, more than 2,000 square miles of land in the Mississippi Delta have disappeared under water.

Babcock Ranch: Florida's first hurricane-proof town - When Hurricane Ian made landfall on the southwest Florida coast, it brought 150 mph winds, 17 inches of rain within 24 hours, and storm surges of up to 18 ft. It was the costliest hurricane in Florida's history, causing more than $112 billion  in damage – and at least 150 deaths. Babcock Ranch is an 18,000-acre development that was sitting in the eye of the storm on the southwest of the state just north of Fort Myers. Built to withstand powerful storms, the town came out relatively unscathed. Is this type of development going to be the only kind economically viable for states like Florida in the future?

Year-round school: Difference-maker or waste of time? – No conclusion in this article….evidently there is renewed interest in the idea in the Southeast. But – the concept is not what most people probably assume. The implementation does not involve more days in school for students and often makes childcare more difficult!

What Are Heat Pump Air Conditioners? - Modern heat pumps are superefficient and can deliver heat down to -15 degrees Fahrenheit…but I had to look to find that they can deliver cool air up to 115 degrees which should have been in the article since it was about air conditioning!

Controversial dwarfism drugs spur growth — but do they improve health? – Hard choices.

Microplastics infiltrate all systems of body, cause behavioral changes – Especially in older mice…behaviors akin to dementia in humans. The changes became more profound in older animals. The microplastics in the study were delivered orally via drinking water…and not in high doses.  It’s scary to think about how microplastics might be impacting humans too.

Can California Cropland Be Repurposed for Community Solar? – Evidently the current farming practices are not sustainable, and some farmland needs to be retired. The idea is that the already disturbed land could be repurposed for new community solar projects. I wondered where the food we now are getting from California will be grown in the future…how robust is the US food production system?

TB research shows a good diet can cut infections by nearly 50% - Improved nutrition in family members of patients in India with lung TB reduced all forms of TB by nearly 40%, and infectious TB by nearly 50%. And…for the patients: An early weight gain in the first two months was associated with 60% lower risk of TB mortality. The other benefits were higher treatment success and better weight gain. During the six-month follow-up period, a remarkable treatment success rate of 94% was achieved.

Top 10 Things You Didn’t Know About Wind Power – How many of these 10 did you know already? I knew 4 of the 10…and knew a little about several others. It’s good to see the progress being made. Kudos to Iowa and South Dakota where over 50% of their electricity generation is from wind energy.

Soils forming on the branches of trees are an overlooked forest habitat – This was a study of a tropical forest in Costa Rica, but it reminded me of a tree along a field trip hiking route in Maryland that I always pointed out to students. It was an old maple that had an indention in its trunk that contained soil about 6 feet above the base of the tree. The tree had grown some roots into that soil and there was moss there. Spider webs filled in. Once we found a shed snakeskin hanging from the area!

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.

Fibromyalgia likely the result of autoimmune problems – Maybe this change in thinking (neurologic to immune system) will improve diagnosis and management of the disease.

How freezing changed the green pea – A little food history

Massive Antarctic Lake Vanishes in Just Three Days – A lot can be learned with observations from space…and once we see something interesting like this there is historical imagery that can provide a view from past years too.

Tuberculosis: The Forgotten Pandemic – The search for a better vaccine for TB….some history of the past 100 years of TB around the world.

Top 25 birds of the week: Bird Interactions! – Birds with others…of their own species and sometimes another bird species.

The Finalists of the Bird Photographer of the Year 2021 Are Announced – Just found this post that came out back in April…enjoy a double dose of bird photos in this gleanings list.

Photos of the Week – June 17, 2021 – Spider photos from The Prairie Ecologist

Fire Destroyed 10 Percent of World’s Giant Sequoias Last Year—Can They Survive Climate Change? – Very sad….and this year there could be more fires.

6 Surprising Tales of Predatory Birds – The 6 birds featured are: pelicans, great blue herons, turkeys, crows, kelp gulls, and vampire finches.

Coelacanths may live nearly a century, five times longer than researchers expected – An ancient form of fish that evidently lives a long time, reaches maturity at about 55 years old and gestates offspring for 5 years. This slow life history has implications for conservation of the fish. I also wondered how many other species we know only from fossils had slow life histories compared to organism we observe today.
