Gleanings of the Week Ending March 30, 2024

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.

Floating Solar Array Is Designed to Take the Rough Stuff - Rich opportunities for solar co-location with offshore wind. By combining floating solar with offshore wind farms and thereby leveraging the same energy infrastructure and export cables, the resulting energy production capacity per used area could be drastically improved. Prototype has been developed…should be in the water by June 2024.

Lessons In Rewilding the Scottish Highlands – Working with nature…increasing biodiversity…reducing monoculture.

Five Shocking Animal Hybrids That Truly Exist in Nature, From Narlugas to Grolar Bears to Coywolves – I’ve heard about a few of these…the pictures were interesting.

Pregnancy advances your ‘biological’ age — but giving birth turns it back - Brewing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA — changes similar to those that are a hallmark of getting older. But new research shows that, several months after a person gives birth, the chemical patterns revert to an earlier state.

Did You Know Sandhill Cranes Dye Their Feathers? – The birds rub iron rich mud onto their feathers…staining them. And some trivia about sandhill cranes at the Platte River (Nebraska) in the early spring:

  • The birds find a lot of waste corn in farm fields, as well as small invertebrates in marshes near the river. A crane can add 20 percent to its weight during two or three weeks in the area.

  • At night, the cranes move to the Platte River for safe roosting in the shallow water.

  • Sandhill cranes are the most numerous of the world’s crane species.

  • In the Central Flyway, more than 500,000 cranes – more than 80 percent of their population.

The heat index -- how hot it really feels -- is rising faster than temperature - Researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days! Arizona's most populous county, covering most of Phoenix, reported that heat-associated deaths last year were 50% higher than in 2022, rising from 425 in 2022 to 645 in 2023. Two-thirds of Maricopa County's heat-related deaths in 2023 were of people 50 years or older, and 71% occurred on days when the National Weather Service had issued an excessive heat warning. With climate change, the relative humidity remains about constant as the temperature increases, which reduces the effectiveness of sweating to cool the body.

158 Cherry Blossom Trees Will Be Cut Down in D.C. in Effort to Withstand Sea-Level Rise – Part of the project to reconstruct a seawall around the Tidal Basin.

Landscape Architecture Strategies Reduce Impacts of Dangerous Extreme Heat – And these apply to what we do in our yard too!

  • Increase tree percentage in parks and green spaces

  • Provide shade on sites

  • Use plant materials and water instead of hardscape

  • Switch to green ground cover, including grasses and shrubs

Plastics Contain Thousands More Chemicals Than Thought, and Most Are Unregulated – Scary! The report also highlights 15 chemical priority groups of concern. These include phthalates, which are used to make plastics more durable and have been found to affect the reproductive systems of animals, as well as per- and polyfluoroalkyl substances (PFAS), which break down very slowly over time and have been linked to health issues including reproductive and developmental problems and increased cancer risk.

Only seven nations meet WHO air pollution standards – The US is not one of the seven: Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand. Bangladesh, Pakistan, India, Tajikistan and Burkina Faso were the top five most polluted countries in 2023 with PM2.5 levels nine to 15 times higher than the WHO's standard. Columbus, Ohio, was the most polluted major city in the United States, while Las Vegas was the cleanest and Beloit, Wisconsin polluted U.S. city overall.

America’s largest transit bus charging station & microgrid open in Maryland – The headline caught my eye because I lived in Maryland for over 20 years – 8 of those in the county where this is happening! I hope other states have the same sorts of projects in the works.

NASA Finds More Than 50 Super-Emitters of Methane – Finding them is only the first step….how many of them will be situations we can reduce or stop the emission?

Iron induces chronic heart failure in half of heart attack survivors – This study prompted testing of iron chelation therapy to remedy or mitigate the effects associated with iron in hemorrhagic myocardial infarction patients.

Unique Bronze Age belt discovered near Opava – Half my ancestors came from the area that is now the Czech Republic…I am drawn to articles about the history of the region.  The belt is quite beautiful…but was it a practical item of apparel?  

What happens if our circadian rhythms are out of whack? – WHO has proclaimed that disrupted circadian rhythms are a probable carcinogen. The study discussed in this post was about the mechanism that circadian rhythm disruption triggers lung tumors.

View 16 Breathtaking Images from the Nature Conservancy’s Annual Photo Contest – Take a little break….look at awesome images of our world.

Mississippi River Basin adapts as climate change brings extreme rain and flooding – This year the stories about extreme weather seem to be more frequent – and wide ranging in terms of water. The Mississippi was low enough for barge traffic to be impacted because of drought…yet there were floods along part of the river just last summer.

Eye-opening discovery about adult brain's ability to recover vision – An unexpected success…opening new ways to treat a vision impairment (LCA) and maybe prompt a re-look about how the adult brain can re-wire itself relative to vision.

The World’s Whitest Paint May Soon Help Cool Airplanes and Spacecraft – A way of making paint that was previously too thick/heavy for things that move. The thicker version works for homes and buildings. We’ll need this technology to reflect heat without expending energy!

Greater cloud cover may be narrowing the gap between daily high and low temperatures – Simulating clouds explicitly. Trying to understand why nights are heating up faster than days across the globe.
