Rare ‘Doomsday’ Oarfish Surfaces in California, Just the 20th Discovered in the State Since 1901 - Usually lives as far as 3,280 feet below the surface. Scientists conducted a necropsy, but they couldn’t discern a reason for the elusive fish’s death. Scientists aren’t totally sure why oarfish and other deep sea-dwelling creatures sometimes surface, but they suspect the animals may be disoriented, sick or injured.

Owl-Inspired “Bionic” Fan for EVs Reduces Fan Noise 50% While Improving Efficiency 10% - Making EVs even quieter!

Do you have knee pain from osteoarthritis? You might not need surgery. – Article written by researchers in Australia about the updated treatment guidelines for knee osteoarthritis that stress exercise, increasing physical activity, weight management, and pain medication (in moderation and not opioids). The links at the end of the article include an online exercise program specifically for knee osteoarthritis.

Frank Lloyd Wright’s Only Skyscraper Set to Close Amid Controversy – Price Tower in Bartlesville, Oklahoma. Built in 1956. Designated a National Historic Landmark in 2007.

Rebuilding the Genome of Woolly Mammoths - Typically, ancient DNA fragments yield short snippets of DNA and provide an incomplete picture of the genomic puzzle. However, the woolly mammoth skin sample showed promise. The team assembled the first 3D reconstruction of the woolly mammoth’s genome, which had 28 chromosomes; the order of genes was very similar to that of the Asian elephant. They discovered: the specimen was female; differences from modern elephants in the genes related to hair follicle development and, more broadly, hair maintenance; cooling and dehydration can preserve the molecules in their original locations.

Homelessness – From Our World in Data. Interesting…but frustrating too. I was glad that they emphasized when the data is not consistently collected…and the analysis gets very tricky.

Only One Country Is Making Progress on Electrifying Everything – Unfortunately it is not the US…it’s China. The country that electrifies most rapidly and builds the most renewables to power its electrified economy will be the most competitive economy globally.

As Arctic Thaws, New Evidence of Looming ‘Mercury Bomb’ - Scientists estimate that the amount of mercury in the atmosphere has grown sevenfold over the last 500 years, primarily from burning coal. Air currents are carrying airborne mercury toward the Arctic, where it is absorbed by plants, which then deposit the toxin in the soil. Over centuries, mercury has built up in the frozen ground, such that today, Arctic permafrost may hold more mercury than the atmosphere, the oceans, and every living organisms combined. As the region warms, melting permafrost could liberate this buried mercury.

Rare Fossils Give Clues to How Tardigrades Survived Mass Extinctions by Hitting the Snooze Button - Tardigrades are known for being some of the most resilient animals to exist, capable of surviving extreme temperatures, pressure, radiation and starvation—they can even withstand exposure to outer space. Only four known fossils of tardigrades have been found to date, and all of them are preserved in amber, or ancient tree resin; recently they were reanalyzed using confocal fluorescence microscopy. Cryptobiosis is the secret to tardigrades’ incredible resilience, and it appears to have evolved in two tardigrade linages (at least). In survival situations, these hardy creatures will expel the water from their bodies and suspend their metabolism almost completely allowing them to outlast unfavorable conditions of their environment.

Five ways the brain can age: 50,000 scans reveal possible patterns of damage - Results could lead to methods that detect the earliest stages of neurodegenerative disease. Dementia and its precursor, mild cognitive impairment, had links to three of the five patterns. Intriguingly, the researchers also found evidence that the patterns they identified could potentially be used to reveal the likelihood of more brain degeneration in the future. Other patterns were linked to conditions including Parkinson’s disease and Alzheimer’s disease, and one combination of three patterns was highly predictive of mortality.

5 Ways Power Sectors Worldwide Can Drive Down Emissions - The coal-to-clean transition is complex — how effective it ends up being hinges on ensuring ambitious climate action integrates priorities around energy security, affordability, reliability, and meeting growth in electricity demand.

The 'dark earth' revealing the Amazon's secrets - Amazonian dark earth(ADE), sometimes known as "black gold" or terra preta, is a layer of charcoal-black soil, which can be up to 3.8m (12.5ft) thick, and is found in patches across the Amazon basin. It is intensely fertile – rich in decaying organic matter and nutrients essential for growing crops, such as nitrogen, potassium and phosphorus. But unlike the thin, sandy soils typical of the rainforest, this layer was not deposited naturally – it was the work of ancient humans. Now businesses are attempting to capitalize on this ancient method, in a quest to help farmers to improve their soil and combat climate change at the same time.

Rusting Rivers - Researchers suspect that thawing permafrost is the cause of dozens of Alaskan streams turning orange. Along with the strange appearance of the water, they have found it tends to be higher in iron, lower in dissolved oxygen, and more acidic than nearby rivers that run clear. The dramatic shift in water quality may be felt most acutely in the villages that rely upon rivers originating in permafrost regions for fish and drinking water.

World’s Largest Green Hydrogen Plant Will Take a Poke at Russian Gas - Mitsubishi is putting up $690 million to help build the world’s biggest green hydrogen plant, to be located in the Netherlands. It will help patch up some holes in the energy independence plan of Europe, where Russian gas has been clinging to a foothold despite sanctions.

Greece Reopens the Palace Where Alexander the Great Was Crowned - The 2,300-year-old Palace of Aigai—the largest building in classical Greece—had been under renovation for 16 years. At 160,000 square feet, the Palace of Aigai was classical Greece’s largest structure. Built primarily by Alexander’s father, Phillip II, in the fourth century B.C.E., it was the home of the Argead dynasty, ancient Macedonia’s ruling family. It was destroyed by the Romans in 148 B.C.E. and endured a subsequent series of lootings.

Predictions For Heat Pump Adoption Trends In 2024 - With $8,000 rebates for space heating heat pumps, and $1750 for water heating heat pumps, the IRA is helping accelerate adoption of this technology.

Miners Discover Seven-Foot Mammoth Tusk in North Dakota - Coal miners in North Dakota have uncovered a seven-foot-long, 50-pound mammoth tusk that’s been buried for thousands of years. Paleontologists have found more than 20 additional mammoth bones so far, including parts of hips, ribs, a tooth. and a shoulder blade.

The new drugs that may bring an end to constant itching - One in five of us will experience chronic itch lasting weeks or months. Fortunately, there might be treatments that address the problem.

Global groundwater depletion is accelerating but is not inevitable - This study shows that humans can turn things around with deliberate, concentrated efforts. Fine resolution, global studies will enable scientists and officials to understand the dynamics of this hidden resource.

Syphilis microbe’s family has plagued humans for millennia - Remains of people who lived on the eastern coast of South America nearly 2,000 years ago have yielded the oldest known evidence for the family of microorganisms that cause syphilis.

Gleanings for Week Ending 6/13/2020

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.

Why some older adults remember better than others -- ScienceDaily – The article seems to be more about the technology that enables these studies….hints at findings that may eventually be actionable.

The World’s Forests Are Getting Younger and Shorter, Research Finds - Yale E360 – This article is a little confusing. It says that ‘climate change is altering the age and structure of the world’s forests’….but it’s more than climate change. It’s also land use decisions (like logging , conversion to agriculture, introduction of invasive species) that have changed the forests. I was disappointed in the article although the last sentence seems obvious: “We as a human society are hitting these forests so rapidly with so many different changes that they can’t keep up.” Now the big question is – what are we going to do about it?

Remains of 60 Mammoths Discovered in Mexico | Smart News | Smithsonian Magazine – North of Mexico City.

Photographer Captures ISS Transiting the Sun in First Solar Photo Shoot – A challenge…requiring lots of planning, practice….and then success!

Top 25 birds of the week: LBBs - Wild Bird Revolution – Little brown birds…. they are everywhere.

Ancient Roman Mosaic Floor Unearthed Beneath Italian Vineyard | Smart News | Smithsonian Magazine – Finally returning to a site first discovered in 1922 and making this find within a week of starting excavations. The mosaic floor is well preserved a few meters below the vineyards surface and is thought to date from the 3rd century AD.

The Infant Gut Microbiome and Probiotics that Work | The Scientist Magazine®  - Evidently the infant microbiome has changed in the past 100 years…even among breastfed babies. And maybe that explains some of the immunologic problems in young children. There are indications that the probiotic helps babies nutritionally and immunologically.

Two bacteria allow spittlebugs to thrive on low-nutrient meals -- ScienceDaily – One of the bacteria uses aerobic glycolysis to process glucose to synthesize 7 essential amino acids plus 2 biproducts that the other bacteria uses to create ATP to produce 3 additional essential amino acids. It’s a similar two cell type process used by cancer cells.

An Encounter with Mating Gopher Snakes – Springtime out in nature…. this article from Idaho.

The gilded mummy of Lady Isaious | Egypt at the Manchester Museum – A Graeco-Roman Period mummy from the 1st century CE.

Unique activities for yesterday:

A large Zentangle tile. I printed a page (on card stock) from The genera of the plants of the United States illustrated by figures and analyses from nature by Asa Gray and Isaac Sprague published in 1848 available from Internet Archive.

Then I used the lotus as the ‘string’ for an 8.5x11 Zentangle tile. Like most strings….it mostly vanished. It took me about three days working for short periods of time to finish. Next time I’ll use more colors so that the botanical print ‘string’ remains more visible.

Filling a Day of Social Distance – 4/3/2020 - Gleanings

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Photographing the sunrise. I seem to get busy and miss the sunrise most mornings…but not yesterday!

Catching up on Charles Cockell’s Life in the Universe Pandemic Series:

• What is all this astrobiology?

• The astrobiology of the night

Noticing more sycamore leaves emerging. There are now three buds that have popped…lots of tiny leaves.

Making experimental face masks from materials I have at home….for when/if we need to go out. I made a mask with a paper napkin, small binder clips, the cut off top of a small gift bag (for the loops). The napkin would be replaced after each use…the rest sprayed with Lysol. It would probably fit better over the nose if I made some pleats. Even better using a scarf (or paper towels) and two hair ties/covered bands. (How to videos I watched). This is all about protecting others; I don’t want anyone to get sick if I happen to be an asymptomatic carrier.

Started Fashion as Design course on Coursera. The week 1 optional 2-hour video of 4 speakers and then Q&A (Under Review and then Reading) on the topic was well worth it.

Links to my previous “filling a day of social distance” posts  here.

And now for the normal weekly gleanings post….

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. 

25 Photos of Madeira's Dreamy Fanal Forest by Albert Dros – Calming nature. It is a quite different forest than the one I see from my office window. Both views are much appreciated.

Tips for how to stay happy in troubling times - BBC Future – Hopefully, some of these work for you. I find that limiting the time I spend catching up on ‘news’ is the one I need to keep reminding myself about; it’s so easy to get absorbed in all the pandemic news (none of it good). I want to be informed but not 24/7.

Monarchs Covered 53 Percent Less Area in Mexico this Winter | The Scientist Magazine® - The last paragraph of the article was the worst news: “The butterflies have already begun their journey north but there is not enough milkweed in Texas to support the butterflies’ reproductive cycle this spring.”

How your personality changes as you age - BBC Future – It seems like there are a lot of positive general trends in personality as we age: more altruistic and trusting individuals, willpower increases, a better sense of humor, more control over emotions. They’re calling it ‘personality maturation’ and it continues until at least the 8th decade of life! And its observed across all human cultures.

Top 25 birds of the week: Eagles - Wild Bird Revolution – Never can resist the birds….

On This Scorching-Hot Exoplanet, a Forecast of Molten Iron Rain | Smart News | Smithsonian Magazine – 640 light-years outside our solar system

Tour A National Park from The Comfort of Your Couch -  Hmmm….I’m going to start working my way through the virtual tours….Maybe one a day?

Unprecedented preservation of fossil feces from the La Brea Tar Pits: A 50,000-year-old Snapshot of Los Angeles trapped in asphalt -- ScienceDaily – The La Brea Tar Pits have been studied for more than a century….but apparently there are still things to learn from them. Fossilized rodent pellets found in context (so definitely not modern, they also were radiocarbon dated to ~50,000 years ago). They are preserved along with twigs, leaves and seeds….an intact woodrat nest!

Massive Mammoth-Bone Structure Found in Kostenki, Russia - Archaeology Magazine – A circular structure about 41 feet in diameter…made with bones from at least 60 mammoths.

Tree Tapping Isn’t Just for Maples – The 2020 season is over for getting sap from trees – this is still an interesting article about how it is done…and other trees that also have sweet sap. I was surprised to see sycamore on the list.
