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)!

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!
