Gleanings of the Week Ending November 4, 2023

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.

Oldest fossil human footprints in North America confirmed – New research that supports the dating of the footprints found in White Sands National Park to between 21,000 and 23,000 years old.

Downtown Dallas Gets a New Park – Harwood Park. It reminded me of a field trip with my parents – taking the light rail train from Carrollton to downtown Dallas to visit Klyde Warren Park and have lunch in 2014. I’m glad there is another park added to the downtown area.

BLM Releases New Plan for Moab Area - The plan limits motorized recreation to protect natural and cultural resources. I hope the BLM can succeed in reducing the impact of off road vehicles….requiring ORV users/organizations to take precautions to protect the environment for themselves and everyone else to enjoy in this area.

Active children are more resilient – Interesting….I’ve assumed this but the way the researches went about confirming the idea was worth knowing and reassuring.

A Road Trip Along the Northern Shore of Lake Superior – The Trans-Canada Highway from Thunder Bay to Marathon in June. Maybe a place we’ll go one summer?

What your hands say about your health – I wish the article had better pictures!

Trouble in the Amazon - In the southeastern Amazon, the forest has become a source of CO2….and maybe more will cease to be a carbon sink as well. Large-scale deforestation… plus even intact forest is no longer as healthy as it once was, because of forces such as climate change and the impacts of agriculture that spill beyond farm borders. Data has been collected every two weeks for 10 years! The selective logging permitted by the Forest Code in Brazil is often not sustainable. That’s because the trees that are removed are generally slow-growing species with dense wood, whereas the species that grow back have less-dense wood, so they absorb less carbon in the same space.

A Summer Light Show Dims: Why Are Fireflies Disappearing? – Habitat destruction (clear cutting, fragmentation of forests), water pollution (in Asia many firefly larvae are aquatic), pesticides and yard chemicals, light pollution (it blinds males so that they can’t find females). On a positive note: firefly ecotourism is increasing in Mexico and Malaysia….and around Great Smokey Mountains National Park in the US.

Large herbivores keep invasive plants at bay - Native plants have evolved such that they can withstand brutal treatment from species of herbivores they have co-existed with for millennia, while invasive plants usually cannot.

The Amazon May Be Hiding More Than 10,000 Pre-Columbian Structures - Based on a new aerial survey and modeling study, archaeologists suggest at least 90 percent of sites known as earthworks remain undetected. Also found - high concentrations of 53 domesticated tree species near earthwork sites. These include cacao, Brazil nut, breadnut and Pará rubber trees, plus dozens of others. This demonstrates how the region’s inhabitants altered the natural landscape, likely so they would have a steady supply of food and useful materials.

Kitchen chemistry hacks explained – How many of these did you know before this article? I knew about lemon juice slowing browning of fruit…I’m going to try the ‘brown onions more quickly’ and ‘chop onions more comfortably.’

Top 10 Things You Didn’t Know About Distributed Wind Power – Interesting update….and map of annual average wind speed at 30 m. There is so much potential in the center of the country. It would be interesting to see the map extended offshore…but maybe that kind of wind power is only used for wholesale generation rather than distributed wind power.

Dust: how the pursuit of power and profit has turned the world to powder – A review of the book about ‘tiny particles doing terrible things’ created by detonation of nuclear weapons, burning coal, and drying of lakes via irrigation. These tiny particles influence our environment, our health, and our relationship with the world around us. They move around the planet through the air…no one is ‘safe’ from them.

More small airports are being cut off from the air travel network. This is why - A shortage of pilots is partially to blame for major airlines' departure from smaller airports. But changing airline economics means the challenge facing regional airports could become insurmountable. Williamsport PA is the example used in the article.

Health evidence against gas and oil is piling up, as governments turn a blind eye – An Australian perspective…but seems to be applicable to many developed countries, including the US. The methane leaks, water contamination, air pollution…why do we continue to push for gas and oil development rather that pivoting to cleaner (and renewable) sources?

Wyoming and Utah Borderlands – A picture from the International Space Station. I remembered a trip to Utah in 2008 where we drove in the area with a Roadside Geology of Utah book explaining the surface geologic features!

New research explains 'Atlantification' of the Arctic Ocean – Changes coming in the Arctic as a 15-year cycle is ending….and the next phase could result in a faster pace of sea-ice loss.

Stone Case Holding Precious Items Found at Templo Mayor – 15 stone figures found at the temple complex of Tenochtitlán, the capital of the Aztec empire. The figures may have already been 1,000 years old when the Aztecs conquered the Mezcala people that carved them. Also in the case: two rattlesnake-shaped earrings, more than 180 green stone beads, snails, shells, and marine corals.

Workers like it when their employers talk about diversity and inclusion - Research has shown that diversity, equity and inclusion (DEI) initiatives improve creativity, innovation, productivity and organizational performance. One of the reasons DEI initiatives have a positive impact is because workers appreciate them. It’s about making sure everyone feels valued and included.

What Does It Take to Photograph a Bat Cave? – Photographer Stephen Alvarez….lots of specialized photographs.

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.

Cold is beneficial for healthy aging, at least in animals – Research with nematodes and cultivated human cells. Both carried genes for ALS and Huntington’s disease. Cold actively removed protein clumps…preventing protein aggregation that is pathological for those diseases. The protease activator that caused the change was discovered…and the impact of temperature explored. Interestingly – “human body temperature has steadily declined by 0.03 degrees Celsius per decade since the Industrial Revolution, suggesting a possible link to the progressive increase in human life expectancy over the last 160 years.”

See Colorful Paintings of the Zodiac Signs from an Ancient Egyptian Temple – Ceiling paintings in a Ptolemaic temple…suggesting Greeks brought the zodiac tradition to Egypt.

 Nearly 1,000 Acres Added to New River Gorge National Park and Preserve – The acres are in the Preserve part of the park. I have visited the park only once…passing through on one of my many trips between Maryland and Missouri. There is a lot to explore there!

Vehicle Exhaust Filters Do Not Remove “Ultrafine” Pollution – Aargh! No wonder there are so many yellow and red air quality days in our cities caused by particulates.

What it really takes for Asia to get to net zero – Home to 5 of the 10 largest emitters: China, India, Indonesia, Japan, and South Korea. An article posted ahead of the BBC’s Sustainability Summit in Singapore. "The perception of higher cost for sustainability practices remains," says An (chief sustainability officer of City Developments Limited in Singapore). "But companies are starting to wake up to the fact that achieving climate goals is an "investment, not a cost."

Thread-like pumps can be woven into clothes – My first thought was maybe these will be commonplace in clothes – enabling us to work outdoors even on very hot days.

Sabertooth cat skull newly discovered in Iowa reveals details about this Ice Age predator – Almost as iconic as dinosaurs when it comes to childhood curiosity about extinct animals. One piece of trivia about modern cats: 40% of lion skulls in a study had survived head trauma to hunt another day. One of the ‘sabers’ of the Iowa Sabertooth was broken not that long before it died…might have even caused its death. Prey fights back…the predator does not always ‘win.’

Europe's unique trials in food 'social security' – Two projects: Montpellier, France and Brussels, Belgium. Run by collectives. The idea that quality, nutritious and organic food should be accessible to everyone.  Each citizen receives a monthly allowance enabling them to buy food meeting certain environmental and ethical criteria. The trials are running for 12 months. The big challenge is changing the way society thinks about food.

The Beauty of Bugs – The picture at the beginning of the article jogged my memory – of the necklace made from insect exoskeletons I saw at the Edge of Cedars State Park Museum when I visited Utah in 2013! I posted about it and took a picture back then…and am pleased to learn more about it and the possible implication it might have re the Basketmaker II culture.

Study investigates source of Amazon’s “Dark Earth” – Created intentionally? It is less acidic than surrounding soils…probably from the addition of ash.

New York City Greenery Absorbing All Traffic Emissions on Many Summer Days – There is a lot more greenery that previously thought…looking beyond parks to modest backyards, shrubbery growing in vacant lots, and trees dotting city sidewalks. That’s good for the summer when everything is green and growing….but it also implies that winter air quality is problematic.

‘Stomp’ Performers Hang Up their Garbage Lids – After 3 decades off-Broadway. Watch the video!

Riddle solved: why is Roman concrete so durable? – It wasn’t just volcanic ash that made Roman concrete better…lime clasts play a self-healing role!

Why is every parking lot covered with solar panels? – Evidently Michigan State has done it…hopefully other universities and big box stores do similar projects. 

How the war in Ukraine is killing marine mammals – The dolphins that were washing up on the shore of the Black Sea prior to the war were few and usually had markings suggesting entanglement in fishing gear.  The theory about the increased number appearing now, without marks, is that the dolphins are experiencing acoustic trauma from the increased use of sonar by Russian submarines.

Climate impact labels on sample food menu had strong effect on food selection – A study done by Johns Hopkins. The result indicate that this kind of labelling could promote more sustainable choices….and have positive health benefits as well!

Aerial Photos Capture the Abstract Beauty of Salt Ponds – From a new book….with images and background about these man-made landscapes.

Great Salt Lake will disappear in 5 years without a massive ‘emergency rescue’ – My husband and I visited the lake back in 2008. The pictures in the article are so different that I needed the captions to recognize the place. The lake was already shrinking in 2008 but the shrinking has increased with long term drought and increased population diverting more water that would otherwise flow into the lake. Aside from the ecological collapse if the lake goes dry, the dust from the dry lakebed is kicked up by winds and can damage lungs/exacerbate other respiratory illness. This does not bode well for public health in Salt Lake City.

Painted skulls from Peru’s Chincha Valley analyzed – The red paint on the skulls was not all the same on all the skulls: some have iron-based ochres and others have mercury-based cinnabar….the red paint on one of the skulls was a combination of the two!

Battle Over Bears Ears Continues in Utah – I am looking forward to visiting Bears Ears and Grand Staircase-Escalante National Monuments and hope that their boundaries stay the way the tribes that have used the area for a very long time want. At some point Utah and the counties that are opposing the size will recognize the values of the tribes and country that want to preserve historical, paleontological, and geologic aspects of these places….and that the state benefits significantly from people visiting. The tourism $ may become more dependable and long term than other uses of the land.

Pyramid and Hundreds of New Kingdom Coffins Found in Egypt - An Old Kingdom pyramid, 300 New Kingdom coffins with well-preserved mummies with names of the deceased, and nearby a pyramid to Queen Neith…a previously unknown Queen.

Long-COVID clinics are wrestling with how to treat their patients – Frustrating situation.

Fenced In: How the Global Rise of Border Walls Is Stifling Wildlife – Border walls have increased since the end of the Cold War! This makes climate change an even bigger challenge to mammals…because they cannot move to better habitat if there is a border wall in the way.

Baby's vaccine responses linked to birth delivery method, study finds – Babies born via Caesarian section have lower antibody levels after vaccinations than babies born naturally.

Scientists Discover More Than 22,000 Endangered Manta Rays off Coast of Ecuador – Larger than any other Manta Ray population.

A Massive Freshwater River Is Flowing Under Antarctica’s Ice – It is flowing at 3 times the rate of the Thames. This finding helps understand some problems with existing models…hopefully it will allow for model updates to predict the impact of warming more accurately on Antarctica’s ice.

A Field Guide to Jackrabbits – Hard to see denizens of the western US (and Mexico).

France Looks to Mandate Solar Panels Over Large Parking Lots – Good idea…maybe it will begin to happen in the US even without a mandate.

Bright LEDs could spell the end of dark skies – Hope cities can learn to use LEDs like Tucson…not overuse bright white LEDs.

Lots of wonderful photography posts to enjoy this week: Winners of the Weather Photographer of the Year Contest Celebrate the Beauty of Nature, West Coast Landscape Photographer Perfectly Captures the Region’s Magical Vistas, Awe-Inspiring Winners of the 2021 Natural Landscape Photography Awards, and Photographer Zooms in on the “Hidden Beauty” of Small Seeds and Fruits – Not sure why there seemed to be so many of these in my feeds this week….

What is Play-Doh made of? – Thinking of toys this time of year….play-doh is something that has been around a long time. We don’t have any young children in our immediate family and I’m missing the joy of watching a child at play.

How your house will go carbon free – Efficiency and renewable energy. At least some of the technologies already exist and many can be retrofitted into existing houses.

Armadillos advance northward as temperature rises – I remember seeing armadillos years ago in Texas when we were camping….maybe we’ll be seeing them closer to Missouri and Maryland in the near future – although hopefully not digging up my yard.

Catching up on Top 25 birds of the week: Breeding and November 2021 – I am ready to do some birding…my husband registered us for a birding hike in a Baltimore hike in December and I hope the pandemic will wane enough that the birding festivals will be back in 2022.

Red, White and Green: Winter Colors in Arches are Awaiting You – My husband and I visited some of the Utah parks in October several years ago…and there was already a dusting of snow on some of the mornings and in the mountains. Maybe we’ll go in November next time.

California Condors Surprise Scientists With Two ‘Virgin Births’ – Maybe this happens in other species too. There was no way to verify the phenomenon before genetic testing became available.  

Seeing Red: What the Color of House Finches Can Tell Us – House Finches are frequent visitors to our bird feeders. It was good to learn more about them from this blog post.

For women, greater exposure to estrogen in life may protect brain regions that are vulnerable to Alzheimer’s – This post left me wondering if estrogen mimics in our environment (i.e. pollution) might be protective as well…and, if so, will younger women be less likely to experience brain shrinkage after menopause than the older generations of women are experiencing.  

Why mandatory vaccination is nothing new – A little history of vaccine mandates. I didn’t know that George Washington required all troops to be inoculated against smallpox in 1777!

Utah’s arches continue to whisper their secrets - GeoSpace - AGU Blogosphere – A study to measure arches to hone 3-D models from the Geohazards Research Group at Universe of Utah. The 30 second video of the model showing how Moonshine Arch moves is worth viewing.

Will the world be quieter after the pandemic? - BBC Future – I know I appreciate having a quieter environment; it’s an aspect of the pandemic that has been positive. The quiet is one of the things I like about my Prius Prime when it is in EV mode. Maybe some of the new norm will involve choices to maintain, as much as we can, the quiet.

Exposure to air pollution impairs cellular energy metabolism -- ScienceDaily – A study from Finland – exploring how particulates impact the olfactory mucosa (a neural tissue located at the upper part of the nasal cavity…the first line of defense against inhaled agents). As I read the article, I wondered if this is the tissue impacted my COVID-19 in people that lose their sense of smell when infected….and also, does wearing a mask filter enough particles to give the tissue a break from other air pollutants.

Renovations Reveal Rare Maya Murals Hidden in Guatemalan Home | Smart News | Smithsonian Magazine – From a colonial home in a mountain village.

Bird feeding helps females more than males -- ScienceDaily – The female cardinals are at my bird feeder much more frequently that the males in both winter and summer. This study doesn’t really point to a reason for that. I’ve always thought that other than the males dominance getting food first….the females might need more food at certain times….when they are laying eggs, for example.

London Foxes Show Early Signs of Self-Domestication | Smart News | Smithsonian Magazine – “Domestication syndrome” – shorter snout and smaller brain.

Painted Vault Revealed at Villa Near Pompeii - Archaeology Magazine – There are new discoveries because they are excavating a part that has not been studied before.

Marine Biologist Braves Cold Water to Photograph Little Known Sea Creatures – Creatures of the ocean….many so delicate they can’t be studied in a lab. Alexander Semenov is a marine biologist and photographer working like a 19th century naturalist, but with 21st century technologies.

Plot Brewing To Blanket US In Solar Panels + Pollinator-Friendly Plants – A beginning…. building hope via steps in the right direction. This article coincided with the MACCEC conference earlier this week. I ended the week more optimistic that the ball is in motion for many ‘drawdown’ actions.

Fish Eggs Can Survive a Journey Through Both Ends of a Duck – The study in this article was done with common carp and Prussian carp…. but what about other invasive species. If most types of fish eggs can survive the duck’s gut - it is bad news for efforts to stop the spread of invasive fish species.

Unique Activities for Yesterday:

Thinking about the first women in my family that could have voted. Women have had the right to vote in the US since 1920 – we’re celebrating 100 years this year. My sister and I have been talking about our great-grandmothers (and maybe the great-great grandmothers too). It’s interesting to think about what it was like in 1920 in our family; they were all citizens by then…although one side of the family were immigrants or children of immigrants.

We wondered if their relationship to immigration and obtaining citizenship would have made it more likely that they would have voted. One of them was divorced with her children teenagers or older; she was educated in Europe before she immigrated. Did her oldest son go with her to vote? The other great-grandmother might have voted as well; she had 3 daughters in 1920 with the youngest being 8 years old (there would be one more after 1920) and they lived on a farm…but went into town often enough. My grandparents from that side of the family always voted, so there’s a reasonable chance that their mothers did to.

One of the things I learned during the recent conversations, is that the grandparents on the other side of the family hosted the local polling place in their garage in the 1940s! That’s an indication that voting was important to them and that could have been passed down from their parents.  One of those great-grandmothers ran a boarding house (around 1920) so she was aware of things going on in town and would have had easier access to the polling place. She insisted that her daughter finish high school a few years later which might indicate that she was attune to the changing role of women more broadly.

I like to think that maybe all 4 of my great-grandmothers voted in 1920…their first opportunity to do so.

Radio Tracking a Rare Crayfish – Cool Green Science – There are a lot more species of crayfish than I realized…and they have a bigger role in the stream that I assumed.

Mindfulness for middle school students: Focusing awareness on the present moment can enhance academic performance and lower stress levels -- ScienceDaily – I wonder if ‘mindfulness’ is something we need to teach more overtly now than in the past because technology and daily life tends to push us in ‘unmindful’ ways.

Canadian Canola Fields – I looked at this article because the Bugs101 course that I took recently mentioned the canola fields of Canada (for some reason I had never known very much about Canola as a crop). This article provides more history. It has become a cash crop for Canada in recent decades.

There's a Troubling Rise in Colorectal Cancer Among Young Adults | The Scientist Magazine® - Incidence of colon cancer is falling in older people…but becoming more common in people under 50. It has continued to go up over the past decade. In young adults, the cancer is discovered later too…usually stage 3 or 4.

A Northwest Passage Journey Finds Little Ice and Big Changes - Yale E360 – Lots of changes. Grizzly are moving northward…fewer polar bears…salmon far north of where they used to be…lungworm killing muskox…plastic in ice cores.

Researchers Discover New Family of Viruses | The Scientist Magazine® - The new viruses are found in lung biomes of people that had had lung transplants or have periodontal disease….many times the patients are critically ill. But we don’t know yet if the new family of viruses are linked to disease.

Utah's red rock metronome: Seismic readings reveal Castleton Tower's unseen vibrations -- ScienceDaily – On the plus side – it does not appear that climbers of the tower are impacting it…but this work is a baseline and there could be some longer term effects. Wikipedia has some pictures and a short article about Castleton Tower.

Infographic: History of Ancient Hominin Interbreeding | The Scientist Magazine® - Still learning about the hominin tree and how modern humans carry the genetic heritage.

Camera Trap Chronicles: The Pennsylvania Wilds – Cool Green Science – I wonder what I would see coming through my back yard. I know we have deer…and I occasionally see a fox. Maybe racoons. My first though was to put a camera on the bird feeder or the bird bath.

BBC - Future - Is there a worst time of day to get sick? – Circadian rhythms are important to health….and our medical system doesn’t use them to advantage. I remember being concerned when my mother was in the hospital years ago and the lights were very bright day and night. No wonder she had difficulty sleeping!

I have a growing list of gleanings from sites that are not operational because of the partial government shutdown; they’ll come out in the list for the Saturday after the sites are operational again.

Climate, life and the movement of continents: New connections -- ScienceDaily – Sediment, which often includes pieces of dead organisms, may create a lubricating effect between plates, accelerating subduction and increasing plate velocity!

Earthquake Damage Detected in Machu Picchu - Archaeology Magazine – Evidence of an AD 1450 earthquake that damaged Machu Picchu is seen in cracks and stone damage of the buildings. The Inca’s modified their construction techniques after the event too.

Shrinking of Utah National Monument May Threaten Bee Biodiversity | Smart News | Smithsonian – Grand Staircase-Escalante is home to 660 bee species, 84 of which live outside of protected land under changes. At a time when we know pollinators are under stress…one more reason why our Federal lands are needed as refuges from human activities that damage the environment.

Scientists Don't Stay for Long in Their Jobs Anymore: Study | The Scientist Magazine® - About half of scientists who enter a scientific discipline drop out after 5 years; in the 1960s, it was 35 years. We are probably training more people in science fields but many don’t stay in academia. This study used publishing records to determine if a person stayed ‘in the discipline.’ I’d prefer to see numbers of people that had careers in a STEM related field rather than just the one they trained in and find another metric than published papers to make the determination. There are a lot more jobs today where people use their science training that do not use ‘publication’ as a measure of success.

BBC - Future - Can we cheat ageing? – Some areas of active research to help us stay healthy longer (may or may not help us live longer).

Corn Domestication May Have Taken Thousands of Years - Archaeology Magazine – It all started 9,000 years ago in southern Mexico. The process continued in Mexico and the southwestern Amazon for several thousand years. It was a slow process.

Ring in the New Year With Dazzling Total Lunar Eclipse of a Supermoon | Smart News | Smithsonian – Hope we have good weather on January 20-21….since it should be visible from our house!
