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.

The chemistry of the coronation crowns – Not included in other reporting of the coronation in the UK…

Surging Brain Activity in Dying People May Be a Sign of Near-Death Experiences – An observation that surges of gamma waves occurred in the brain of two comatose patients when they were taken off life support and their heart stopped. Not enough evidence yet to know if this is a mechanism that happens more frequently at death…but it is an intriguing possibility.

A special omega-3 fatty acid lipid will change how we look at the developing and aging brain – Perhaps something that will develop into a treatment to help sustain myelin sheaths of our nerves better as we get older.

The puzzle of Neanderthal aesthetics – More evidence that Neanderthals might have been capable of the kind of complex symbolic concepts and behaviors that characterize our own species.

A Brighter Future for Attwater’s Prairie Chickens – Native to the coastal plains for Texas and Louisiana. Overhunting (commercial markets and shooting contests), land development, fire ant invasion…by the 1990s, fewer than 100 birds remained in the wild. Captive breeding began with some success. Hurricane Harvey wiped out nearly 90% of the wild population in 2017. Landowners have enlarged the habitat available to the birds…and there are now at about 250 wild birds.

Busts Provide New Insight into Spain’s Tartessos People – Carved of stone…dated to 5th century BC. Not much is known about the people except that they were goldsmiths.

Supreme Court Slaps Down Fossil Fuel Companies — Five Times! – Good news….the power of litigation as a tool for climate action can continue to move forward.

People who think positively about aging are more likely to recover memory – There is a power in positive thinking!

What causes the scum on tea? – Calcium and bicarbonate ions are the culprits. Adding lemon juice can be the cure!

Six ways to lower your carbon emissions quickly – The easiest one for me is to not fly; my husband and I haven’t flown for the past few years (since before COVID-19)!

Gleanings of the Week Ending December 31, 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.

Best of 2022 - A Fun Map Puzzle – There are parts of the world where political boundaries have changed a lot since my elementary school geography class. The MapPuzzle game is a fun way refresh (or relearn) countries/states/provinces.

The year in chemistry: 2022’s biggest chemistry stories – I like these summary articles…and think about which one of the stories will be the most impactful in 2023.

Top 7 Building Decarbonization Wins In 2022 – Finally….now to maintain the momentum of these ‘wins’ and more into 2023!

Ten Remarkable New Plants Discovered in 2022 – And one of them is the largest waterlily on Earth…from Bolivia.

Shrinking Pollinator Populations Could Be Killing 427,000 People Per Year – The world is losing 3-5% of its fruit, vegetable, and nut production because of shrinking pollinator populations and lower pollinator diversity. That translates into less healthy food available…and associated health conditions like diabetes and heart disease. In Honduras, Nepal and Nigeria, the pollination deficits are responsible for a reduction of 3-19% in crop yields. This highlights the importance of making changes to support pollinator populations such as limiting pesticide use, maintaining existing natural habitats, and restoring others, and planting more flowers and diverse plants.

Overlooked Gems of The National Park System – In the cold of winter…time to plan some trips to parks for the year…including a few of the overlooked gems highlighted in this article.

Snow Day in Delmarva – Reminder of the area where we enjoyed a lot of day trips while we were living in Maryland….

Stunning Satellite Images of Our Changing Planet in 2022 – The before and after pictures have different elapsed times…be sure to read the captions.

22 Photos Honoring the Triumphs and Challenges That Face Wild Cats – A collection of pictures from Panthera, the world’s leading wildcat conservation organization.

Home Depot Does a Big Energy Deal, But It Does More Behind the Scenes – The Home Depot commitment is to produce or procure 100% renewable electricity equivalent to the needs of all its facilities by 2030 and they are taking actions to make it happen. Hope more big box stores will be taking similar actions.  

Gleanings of the Week Ending June 18, 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.

Archaeologists Uncover Hundreds of Colorful Sarcophagi at Saqqara—and They’re Not Done Yet – The seeming endless interest in Egypt…sustained by continuing new finds.

8 cool wild cats you probably don’t know – So many wild cat variations!

Fjords emit as much methane as all the deep oceans globally – When storms churn up water in fjords….oxygenating the fjord floor…methane emissions spike. If the water mixed more frequently the methane emissions would drop because anoxic environments at the bottom of fjords would disappear.

Tree rings are evidence of megadrought – and our doom – Tree ring data indicates that the 22-year period from 2000 through 2021 was the driest and hottest in the last 1,2000 years for the North American Southwest. There was another 22-year drought from 1571-1592 that was nearly as dry but not as hot as the current drought. And the water distribution allocations were made based on a 22-year period between 1900 and 1921 that we now know was an anomalously wet period for area! Not good signs for the future.

A 3400-year-old city emerges from the Tigris River – Drought lowered the Mosul reservoir. There was a quick survey…discovery ceramic vessels with 100 cuneiform tablets…and the conservation measures to project the site as the water rose again. The site is now completely submerged.

Fifty years later, Kim Phuc Phan Thi is more than ‘Napalm Girl’ – One of the most iconic photos of the Vietnam war…still makes be as emotional now as the first time I saw it. She says – To confront violence head-on…’the first step is to look at it.’

Two articles about the flooding in Yellowstone: Repairing and reopening Yellowstone National Park won’t be easy and Extreme flooding devastates Yellowstone, forcing the closure of all park entrances – Very sad….also scary.

Wildlife bedtime: weird nesting habits of North American wildlife – Black bears, black-footed ferrets, jumping spiders, bald-faced hornets, and red-sided garter snakes.

How Vivian Maier, the Enigmatic Nanny Who Took 150,000 Photographs, Found Her Place in History – Street photographer…that only became known after a storage locker of her photographs/negatives was auctioned off when she couldn’t make the payments on it.

Zapping orange peel oil into new, pleasant aroma compounds – I’ve always liked the smell and taste of orange peel (I buy organic oranges and use the whole orange!) but evidently the compound that is in orange peel, limonene, can be the starting platform for other scents as well.

Gleanings of the Week Ending January 8, 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.

2021 Year In Review: Top Stories From The National Parks – Lots of perspectives in these ‘top stories’ – lots of challenges but some room for hope in 2022.

Earth in 2021 – A 3-minute video summary from NASA….lots of before and after catastrophic events. The text in the post has a short description of the events in the video.

Top 25 birds of the week: Birding! – Bird photographs…always a great look.

Stopping dementia at the nose with combination of rifampicin and resveratrol – The research was done in mice…they started preparation for human clinical trials in November. If it is effective in humans and can be produced/distributed economically, it could be a boon for aging populations around the world.

Saguaro National Park – A place I visited frequently while by daughter was in Tucson for graduate school. It’s interesting how they are monitoring the keystone species in the park…concern is that fewer young saguaros are surviving these days.

Climate-driven weather disasters inflicted billions in damage in 2021, study says – The cost of climate change already is impacting economies around the world….doing something to reduce/mitigate climate change is quickly becoming the option that makes the most economic sense for everyone.

Poison Ivy – You don’t want to touch it…but it’s best left alone when it’s growing in a place where people are unlikely to contact it. Its berries provide food for birds in the winter, it does not hurt the trees it climbs, and its leaves turn red in the fall.

Chalk steams: why ‘England’s rainforests’ are so rare and precious – This article brought back memories of wading in chalk bottomed creeks in the Dallas, TX area when I was teenager. I don’t remember much about the plants and animals…more about the fossils weathering out of the chalk.

2021 Year In Review - Another Year of Photography During The Pandemic – Beautiful places…and some little photography lessons too.

The year in chemistry: 2021’s biggest chemistry stories – 2021 was quite a year for big chemistry stories! Several of them are likely to have high impact for years to come.

Gleanings of the Week Ending September 25, 2021

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.

Top 25 birds of the week: September 2021 – Such a variety of birds in the world!

The Love Stories of Sleepy Lizards – An Australian lizard…they are monogamous and have a surprising threat display. They have been studied for over 40 years.

Searching for the Fisher Kings – The Calusa of south Florida…a capital on a man-made island made of shell. Surviving the Spanish but not the British.

New Coal Plants Dwindle Amid Wave of Cancelled Projects – Good! We need to be ramping up generation of electricity with renewables….and dramatically reducing the methane released by the oil and gas industry in their extraction processes…and then begin to reduce our need for oil and gas in areas that can be electrified (like transportation and heating/cooling).

Explore Life Under the Microscope with the Winners of the Nikon Small World Photomicrography Contest – Photomicrography frequently creates art from reality that it too small for our eyes to see without the magnification and specialized equipment.

August 2021 global climate summary – From NOAA. Two global maps (temperature and precipitation). Where I live, August was hotter and slightly wetter than the average (averages from 1981-2010 for temperature…from 1979-2020 for precipitation).

People synchronize heart rates while listening to stories – Thinking about the brain as part of physical body….looking at the brain-body connection more broadly.

Study Links Transportation Noise to High Rates of Dementia and Alzheimer's – From Denmark.

Indigenous Resilience Center Launched at the University of Arizona – My daughter did her graduate work at University of Arizona; I’m glad they are launching the center to find and implement culturally appropriate solutions to the challenges of climate change.

The chemistry of dahlia flower colors – Also explains why there are no blue dahlias.

Filling a Day of Social Distance – 4/24/2020 - Gleanings

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

Here are the unique activities for yesterday:

Finishing Fashion as Design Coursera course. The theme for the last module was Expression. It was a good way to end the course. I have enjoyed both courses I’ve done from MoMA and will probably start a third one – What is Contemporary Art – early next week.

Hearing a piano practice. My husband opted to start up piano practice…not sure why he hadn’t thought to play it weeks ago. What’s not to like about a grand piano? It was tuned last winter just before the coronavirus pandemic, so it is in excellent condition. His playing didn’t last for long, because the cat demanded attention…and has decided that the best place to sleep is under the piano.

And then there are the gleanings for the past week:

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.

How Rain Evolved Its Distinct Scent—and Why Animals and Humans Love It | Smart News | Smithsonian Magazine – The chemical that is the scent of newly moistened soil, geosmin, has been known to scientists since the 1960s….but now we are figuring out its purpose. It is made by 120 of 122 species of bacteria in the genus Streptomyces that have been studied. The scent attracts springtails (tiny arthropods) that eat the bacteria and spread the bacteria’s spores via their excrement or the spores that attach to their body and then fall off. Many other insects, fungi and nematodes are killed by chemicals produced by the bacteria. So – the scent after rain is connected to the lifecycle of bacteria that are one of the most important sources of antibiotics known to science!

Top 25 birds of the week: Terrestrial Birds - Wild Bird Revolution – Enjoying images of birds from around the world.

Long-living tropical trees play outsized role in carbon storage -- ScienceDaily – They used ‘hindcasting’ to validate their model: seeded the model with forest composition data collected at their site in Panama during the 1980s and then ran the model forward to see that it adequately represents the changes that occurred from then until now.  Once that was done…they can use the model to predict what will happen to the forest with climate change. Will the forest continue absorbing some of the excess carbon – or not?

Flamingos in Captivity Pick Favorite Friends Among the Flock | Smart News | Smithsonian Magazine – 2-4 birds…not limited to mated pairs. Some were together for the whole 5 years of the study! The study found no loners but some bounded between groups.

What do soap bubbles and butterflies have in common? Butterfly breeding gives insight into evolution of iridescence -- ScienceDaily – A 75% increase thickness in the chitin lamina of wing scales turned iridescent gold to shiny blue….the same way a soap bubble iridescence works! And now there is a whole new genetic approach to investigate structural color in butterflies – and may lead to new ways to produce photonic nanostructures for solar panels, paints, clothing, and cosmetics.

How to mine precious metals in your home - BBC Future – Theoretically - the “urban mine” is far richer in high value materials per ton than traditional metal ore mines….but we don’t quite have the way to collect the ‘ore’ or effectively extract the metals.  

Springfield Plateau: Cowbird Eggs – Cowbirds….I’m trying not to be too judgmental. (I’ve included a picture of cowbirds at our bird feeder below. The female is a more frequent visitor than the male.)

Colorful Image Lights Up Microscopic Guts of 'Water Bear' | Smart News | Smithsonian Magazine – Enhancing our view of a tardigrade with fluorescent stain….and done close to where I live at University of Maryland Baltimore County!

Take a Free Virtual Tour of Five Egyptian Heritage Sites | Smart News | Smithsonian Magazine – These are best viewed on your largest monitor!

Common protein in skin can 'turn on' allergic itch -- ScienceDaily – Turning off the production of the protein periostin in the skin can reduce the itch from atopic dermatitis (in mice). More research needed to see if it works for humans too.

Gleanings of the Week Ending May 11, 2019

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.

Epic Proportions - Archaeology Magazine – Standard measures of Stonehenge and other Neolithic monuments?

Potassium: Soaps and radioactive bananas | Compound Interest – Potassium regulates blood pressure and transmission of nerve impulses in our bodies!

Colorful Birds  and Terrestrial birds – From the National Geographic Society. Still catching up on the backlog. I enjoy birding – and seeing birds in action…and photographs of birds taken by others. That’s why these photographic collections show up on my gleanings list.

BBC - Future - The princess who transformed war medicine – A little medical history not widely known from the early 1900s.

Ancient secrets of medicinal mint -- ScienceDaily – There are so many members of the mint family. This article is about the DNA sequencing from a plant…learning how to more rapidly tap the therapeutic benefits of that plant and the mint family at large.

Four Out of 10 Americans Breathe Unhealthy Air - Yale E360 – That’s 141 million people…up 7 million since last year….partly due to impacts of climate change on air quality. So – we need to find ways to clean up air better than we do now either by reducing emissions or cleaning them out once they are produced.

Aging gracefully: Study identifies factors for healthy memory at any age -- ScienceDaily – The good news is that some of the factors are things we can control - engaging in more social activities, more novel cognitive activities, losing excess weight, and living with others.

What is a Naturalized Outdoor Learning Environment? -The National Wildlife Federation Blog – Early Childhood Health Outdoors (ECHO) program….daily access to the outdoors for young children. When I was growing up, we were outdoors most days but that is not happening consistently these days. I applaud the initiatives that are honing ways to get children outdoors more.

Your Questions About Food and Climate Change, Answered - The New York Times – A hefty article on the topic…with pull down details.

Medical guidelines may be biased, overly aggressive in US -- ScienceDaily – Thought provoking. How is a patient to know when a doctor recommends a test or procedure that it is truly in the best interest of the patient when the doctor has a financial interest in the recommendation, or the doctor is so specialized that they always think their specialty is the best solution?

Gleanings of the Week Ending May 4, 2019

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.

Exploring the Parks: White Sands National Monument – Another place I want to return to and spend a bit more time. I’ve been once when we were on the way from Dallas to Tucson. I posted about it back in 2013. We stayed long enough to have a picnic, walk along the boardwalk trail, and photograph cliff swallows at the visitor center.

New Analysis of Depression-Era Fossil Hunt Shows Texas Coast Was Once a 'Serengeti' | Smart News | Smithsonian – Research on collections made by the Works Progress Administration and mostly just stored since the 1940s….Other states than Texas probably have research projects on these collections as well.

IYPT 2019 Elements 020: Calcium: Teeth, bones and cheese | Compound Interest – Another article in the International Year of the Periodic Table series. Did you know that the human body contains about 1 kilogram of calcium?

Image of the Day: High Contrast | The Scientist Magazine® - The milkweed bug! The milkweed is just beginning to come up so I haven’t seen any of these bugs yet this year…but they’ll come out soon enough. I’ll try to remember some of this article next time I see the bug with a group of field trip hikers!

12 Famous Flower Paintings, from Monet to Mondrian – A little eye candy. Notice that there are insects with the flowers in the Ambrosius Bosschaert painting.

An invasive, thorny tree is taking over Africa – can it be stopped? – It’s not just the US that has problems with invasive plants and animals brought from elsewhere in the world. The Mesquite tree that is problematic in Africa came from South America.

Top 25 Wild Bird Photographs of the week: April and Waterbirds – Catching up a little on the series…two this week and there are still some left for the next gleanings collection.

‘Exquisitely Preserved’ Skin Impressions Found in Dinosaur Footprints | Smart News | Smithsonian – The prints are from a small theropod. Not only do they show the impression left by skin…they also indicate the dinosaur was in Korea earlier than previously thought (10-20 million years earlier).

Electric Cars Could Be as Affordable as Conventional Vehicles in Just Three Years - Yale E360 – EV technologies are developing rapidly. In 2015, batteries made up 57% of the EV total cost; today it’s down to 33% and by 2025 the projection is 2025. I know that I have enjoyed my plug-in-hybrid and that my next car will probably be an EV.

Clean Tech Jobs Lead Employment Statistics in Many US States | CleanTechnica – The map is worth the look. Solar panel installer or wind turbine service technician is the fastest growing type of job in 11 states!
