Gleanings of the Week Ending January 1, 2022

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.

Spruce Tree House – extreme rockfall management – It’s been decades since I visited Mesa Verde, but I’m still drawn to any articles about it. This one was a reminder of the fragility of the place from a geologic perspective.

4 of the biggest archeological advancements of 2021 – including one ‘game changer’ – I always browse these end-of-year summaries…catch up on any big things that I somehow missed when they were originally in my news feeds.

No more annual flu shot? New target for universal influenza vaccine – Wouldn’t it be nice if this could happen? Even if they did develop a vaccine effective against all strains of influenza…would we still have to get boosters (i.e. would our immunity fade over time)?

With omicron, you need a mask that means business – I’ve been wearing KF-94 masks since February. My Christmas present from daughter was some patterned ones…although I still have a good supply of the black (the Ninja look) ones. I wear one anytime I am indoors (and not at home) and if I am outdoors with a lot of people around. Now that it’s cold, I wear them for warmth too; it’s surprising how much the mask keeps the nose and face comfortably warm….and the mask seals well enough that my glasses don’t fog!

Climate Clues from the Past Prompt a New Look at History – Some examples of the outsized role of climate in human affairs….and the interdisciplinary contributions to papers on the topic.

As Wetland Habitats Disappear, Dragonflies and Damselflies Are Threatened with Extinction – Maybe we need to start thinking about having wetland/ponds in our gardens as well as pollinator gardens…reduce the ‘lawn’ part of the area around our houses.

Forest Keepers: The National Park System is an essential laboratory—and also a battleground—in the management of invasive pests – The invasive pest pictured at the top of this article is woolly adelgid…something a learned to recognize in our area of Maryland…that has killed most of the hemlocks. Some of the trees growing in parks were saved with aggressive treatment, but the ones in the forest behind our house are gone.

New smart-roof coating enables year-round energy savings – A technology that changed the reflection/absorption properties of the roof based on temperature would be another step toward increasing the energy efficiency of buildings….reducing the heat island that plagues cities.

Study shows critical need to reduce use of road salt in winter – This has been a topic in several water quality sessions I’ve attended overthe past few years in Maryland. I have noticed the spraying of brine prior to storm events in our area so maybe some jurisdictions are already following the suggestions in this article.

Inside Idaho’s Campaign to Include Indigenous History in Its Highway Markers – Good idea; history of the US is more than European colonization. This article also prompted me to wonder if there are web sites that document the location and text of highway markers. I did some web searches and found several at the state level…and a general one: https://www.hmdb.org/

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.  

Shrikes: Meet the Bird That Impales Prey on Spikes – The bird creates its “pantry” on barbed wire…other spikey objects. Gruesome…but it’s an adaptation that works for the bird.

The color of your clothing can impact wildlife - ScienceDaily – For water anoles – orange is better than green if you want to see the lizards!

We're Destroying Virgin Forests for Toilet Paper -- What Are the Alternatives? | CleanTechnica – Not good! We in the US are the biggest users…change is hard.

Why Clouds Are the Key to New Troubling Projections on Warming - Yale E360 – Fewer clouds as the planet warms? If so, we’ll heat up more because more solar energy will strike the planet. That’s what the most recent models are predicting and real-world data from satellites suggests that the modelers’ predictions may already be coming true. We’ll have less snow and ice around too to reflect solar energy back into space. It seems like we should make all sky facing manmade surfaces (like roofs) white or lighter colored (unless they are generating energy)…and look for other opportunities to reflect like clouds.

New Research Rewrites the Demise of Easter Island | Smart News | Smithsonian Magazine – There is mounting evidence that Easter Island people created the statues until at least 1750 – after contact with Europeans. And their population has been relatively stable since the 1400s. By the time the British explorer James Cook arrived in 1774 the statues were in ruins. By 1877, just over 100 people remained on Easter Island.

How do woodpeckers avoid brain injury? – Woodpeckers avoid concussions with some adaptions: 1) specialized skull bones, neck muscles, beaks and tongue bones 2) less internal fluid surrounding their brain to limit the motion of the brain during pecking. Interesting…and maybe can help devise ways to protect and heal human brain injuries.

Anti-solar cells: A photovoltaic cell that works at night -- ScienceDaily – Some research…potentially a way to balance solar power over the day-night cycle.

How did the last Neanderthals live? - BBC Future – From caves in Gibraltar….the insight that they were much more like us than we once believed: they exploited seafood and marine mammals (they could swim…hunted dolphins), wooly mammoths, woolly rhinos, ibex, birds (maybe used their feathers…particularly the black ones); they decorated walls and shells; their hyoid bone was like ours (which means they might have had speech like ours); they made tools of bone that were copied by modern humans.

Florida scientists study health effects from exposure to toxic algae - UPI.com – Blue-green algae toxins make people sick (liver damage/disease, skin rashes, headaches, trouble breathing) but does it cause disease when it is absorbed via breathing (i.e. airborne particles) during algae blooms? Fish kills are bad too. It’s good to research the topic but shouldn’t we do everything we can to prevent the blooms in the first place?

Researchers Find Cell-Free Mitochondria Floating in Human Blood | The Scientist Magazine® - Surprise! Now to figure out their function….

Neandertal slaughters · john hawks weblog – Analysis of 5 sites indicates that Neandertals were excellent tacticians, casual executioners, and discerning diners.

Rare Gemstone Hidden in Ancient Teeth Reveals a Surprising Truth About Medieval Women – Lapis Lazuli found in the remains of a middle aged woman’s teeth and jaw. She was buried in an all-female monastery in Germany sometime around 1000-1200 CE. The researchers concluded that she most likely was painting with the pigment (licking the end of the brush while painting) creating manuscripts.

More solutions needed for campus hunger – A new report states that 9-50% of America’s college students face food insecurity…and that does not include graduate students. There are some programs that could help but often the students are not aware of them…and there may be enough stigma attached to them that students shy away. These are young adults that need adequate nutrition to continue their schooling and growth into adulthood.

Image of the Day: What We've Dumped | The Scientist Magazine® - Yuck! Stuff that washed up on 12 shoreline sites on barrier island along the US Gulf Coast…and it’s all stuff that people put in the water.

US Cancer Death Rate Dropped for 25 Years Starting in 1991 | The Scientist Magazine® - Down 25% over 27 years…a positive trend.  But there are still issues of race and socioeconomic inequality when it comes to prevention and treatment. The trend is not good for obesity related cancers; they are on the rise.

Top 25 Wild Bird Photographs of the Week: December – National Geographic Society Newsroom – I always like bird pictures.

Natural Disasters Caused $160 Billion in Damage in 2018 - Yale E360 – It did seem like there were a lot of disasters last year: fires in California, Hurricanes Michael and Florence…and that’s just the ones in the US.

Medical marketing has skyrocketed in the past two decades, while oversight remains limited -- ScienceDaily – I have been suspicious of medical marketing (particularly ads on television) for some time. The study seems to show that state and federal regulators are overwhelmed.

Image of the Day: Geckos on the Run | The Scientist Magazine® - It must take a lot of energy for the gecko…but it can indeed run across the surface of the water.

The Acoustics of Ancient Greek Theaters Aren’t What They Used to Be | Smart News | Smithsonian – Legendary acoustics? Maybe not. But they are still very good even with the changes in the structures over time (pitting of smooth surfaces, no backdrops, etc.)

BBC - Future - The useless design features in modern products – copper rivets and watch pockets in jeans, cockpits with analog dials/leavers/knobs, and keyboard layout. The look of modern products has a lot to do with history!

Five Things to Know About the Yellowstone Supervolcano | Smart News | Smithsonian – I can remember my daughter being fascinated that Yellowstone is a Supervolcano when we visited. She was enthusiastic about finding a book about it and was puzzled when the person manning the bookstore seemed surprised that she wanted a book about super volcanoes!

Keeping Your Balance as You Age | Berkeley Wellness – Some reasons to do some balance exercises…and some easy ones that don’t need any equipment.

Some items about a favorite food around Thanksgiving: Pumpkin genomes sequenced, revealing uncommon evolutionary history -- ScienceDaily and 7 Pumpkin Recipe Ideas | Berkeley Wellness

Caribbean’s largest concentration of indigenous pre-Columbian rock art -- ScienceDaily - Artists before Columbus: New research on the Caribbean’s largest concentration of indigenous pre-Columbian rock art (how it was made, paint recipes). The pictographs are in very narrow spaces deep in caves. Follow the materials link at the bottom of the article to see some images. As I read the article, I realized that the research had probably been completed before the recent hurricanes.

Older Neandertal survived with a little help from his friends – Loss of a forearm, deaf…and he survived into his 40s…about 50,000 years ago.

The Weird Growth Strategy of Earth’s First Trees | The Scientist Magazine® - The first tree grew large very differently than modern trees!

4 Myths About Meditation and How to Overcome Them | Berkeley Wellness – For me – the ‘myths’ are no so important…the mediation is.
