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.

What links litmus paper and lichens? – How did I not know that litmus dye was made from lichens? I remember using red cabbage to tint paper for an elementary school science project with my daughter. We tested everything in the house…discovered that even the fumes from toilet bowl cleaner turned the strips we made bright pink!

How donkeys changed the course of human history – The beast of burden. During Roman times the subspecies used was larger than modern donkeys…specifically bred for the expanding empire.

Jungle realm of the Snake Queens – A 5-part article about 2 Mayan queens: Lady K’abel and Lady Six Sky.

Marriage in Minoan Crete – A surprise – it was very common to marry one’s first cousin!

Kenya’s Rift Valley lakes are rising, putting thousands at risk – A study reveals that there have been increases in rainfall since 2010…an increase of only 0.4-2% of mean annual rainfall leads to the observed rising lakes/flooding.

EPA requirement keeps electric buses out of low-income schools – Low-income school districts often don’t own their school buses; they rely on contractors or subsidized lease deals. So --- they can’t meet the requirement to scrap the old diesel buses.

Ten-minute scan enables detection and cure of the commonest cause of high blood pressure – The hormone aldosterone causes 1 in 15 cases of high blood pressure. This new technology/treatment is a big improvement for the way those cases can be treated.

Dead Humpback Whale Washes Ashore at Assateague Island – This is the second one recently. I am familiar with the place this time…Assateague Island was a place my husband and enjoyed for birding when we lived in Maryland.

China’s population declines for the first time in six decades – Changing demographics in China.

Bees exposed to common weedkiller via wildflower nectar – Evidently the flowers can be contaminated even if they are not sprayed directly!

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.

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.

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 Tucson, Arizona is facing up to a 1,200-year drought – Harvesting rain!

The demented gift American politicians handed to China – About electric buses….and more. The suggested acronym by the author: GAGA (Give American Greatness Away).

New clues into a serious neurodegenerative disease – So many sources of cognitive decline….and we are just beginning to understand some of the mechanisms (and thus effective treatment). The research described in this post is about frontotemporal dementia.

World headed in wrong direction one 5 key mechanisms of climate progress – And the 5 are: share of unabated fossil gas in electricity generation, carbon intensity of global steel production, share of kilometers traveled in passenger cars, mangrove loss, agricultural production of GHG emissions.

Researchers reveal why shingles can lead to stroke - The risk of stroke is elevated for a year after having shingles. This study found that prothrombotic exosomes which can cause blood clots are found in those with shingles…and persist after the outward symptoms of shingles are gone. Using antiviral agents longer with the addition of antiplatelet and anti-inflammatory agents could help reduce the risk of stroke.

Will we ever…. live in city sized buildings? – Maybe. But would it be pleasant? Maybe an apocalyptic event would force us to do it to survive.

Vitamin D deficiency linked to premature death – The study evaluated 307,601 records from the UK Biobank. Take away message from the results: ensure that vulnerable and elderly maintain sufficient vitamin D levels throughout the year.

Omicron keeps finding new evolutionary tricks to outsmart our immunity – Variants within a variant!

Powerful Aerial Photos Show the Consequences of Drought on the Colorado River – The dry situation in the western US.

Cats react to ‘baby talk’ from their owners, but not strangers – And does this mean we are more than just a food provider in their world?

Gleanings of the Week Ending July 30, 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.

Furs from Danish Viking Burials Analyzed – Proteins extracted from animal furs found in 6 burials. The accessories/furnishings were domesticated animals. The items of clothing were wild beaver, squirrels, and weasels. The beaver furs were not native to the area so were probably luxury furs obtained by trade.

More Energy on Less Land: The Drive to Shrink Solar’s Footprint – Good ideas…if we must use agriculturally productive land for solar panels. I’d like to see cities with high density solar panels that generate electricity close to where it is needed (i.e., short distance between generation and use). Hopefully that is happening in parallel with the solar development described in this article.

Moths are unsung heroes of pollination – The study was done with red clover…but probably applies to a broader range of plants. Moths are active during the night so have not been as easily observed as pollinators that are active during the day. The work was done with time lapse cameras.

Electric School Buses! – A blog post about the US Department of Energy’s ‘Flipping the Switch on Electric School Buses’ series. There are lots of communities that have been exploring making the transition and I am hopeful that it will be an escalating trend. I always cringed at the fumes that were so obvious when the buses arrived/departed from schools as I was growing up and when my daughter was in school. It would be good for the planet and good for children’s lungs to eliminate the school bus as a source of air pollution!

The habits that help prevent allergies – Studies that are improving our understanding of why allergies are increasing in the children….and strategies for addressing the problem. Evidently the time between 4 and 11 months is very important.

Harm from blue light exposure increases with age, research in flies suggests – Not good news. Maybe the default setting on our ‘screens’ (phones, computers, television) need to reduce blue light rather than it being a setting that everyone must intentionally set. And why don’t LED manufactures offer bulbs that are not so blue shifted?

Giant Snails take over Florida’s Gulf Coast - It is not the first time…probably won’t be the last. These snails are native to Africa and this the third time Florida has battled an invasion.

Water resources to become less predictable with climate change – The study focused primarily on areas that rely on snow for all or part of their water supply. Some of those areas are already relatively dry…and the populations are large enough that the unpredictability of water resources will be very problematic.

The best way to brush your teeth – This is going to take some practice to break old habits. I learned to brush my teeth a long time ago and probably am too sloppy even doing it the way I was taught!

New thought on Cahokia’s ancient wetlands – A large flat rectangular area that was previously thought to have been used as open, communal space might have been under water most of the year!

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.

Domesticated chickens have smaller brains -- ScienceDaily – 10 generations from wild junglefowl toward domestication….and they already had smaller brains.

750 Million GM Mosquitoes Will Be Released in the Florida Keys | The Scientist Magazine® - Reducing yellow fever and dengue carrying mosquitos at a time when more mosquitos are becoming resistant to pesticide-based controls. Texas might be the next place this technique will be used – pending state and local approval.

Earthquakes and insects on Alaska road trips - The Field - AGU Blogosphere – I browsed this article and remembered learning about the 1964 earthquake from the Weekly Reader in elementary school. So -this was an update about what the place is like today…with the town moved completely.

Nuvve And Blue Bird Combine To Create Electric School Buses That Are V2G Enabled – I wish all new school buses would be electric…and charged via renewable means…for the planet and, more directly, for healthier air for young lungs.

Top 25 birds of the week: Colours - Wild Bird Revolution – Beautiful birds….I never get tired of looking at images of the diversity in color and form the birds display.

The U.S. drought vulnerability rankings are in: How does your state compare? | NOAA Climate.gov – Looking at states that I know well because I have family members living there Maryland, Texas and Missouri have a high ability to adapt whereas Oklahoma has a very low ability to adapt (because they have an outdated drought plan and limited irrigation combined with extensive agriculture and cattle ranching). Is Oklahoma headed toward another dust bowl?

Five myths about wildfires - BBC Future – The 5 myths debunked in this article are: regularly logging forests prevents forest fires; there is nothing you can do to protect your property; wildfires are an inevitable fact of nature; all wildfires are bad and must be quenched immediately; it is possible to eradicate (control) all wildfires

Thousands of species recorded in a speck of soil -- ScienceDaily – DNA was extracted from permafrost samples representing different points in the Pleistocene - Halocene transition (about 11,000 years ago). Genetic remnants of animals like mammoths, horses, bison, reindeer along with 1000s of plant varieties were found!

The remarkable floating gardens of Bangladesh - BBC Future – Planting on floating rafts….large scale hydroponics that is not greenhouse based.

4 Fun + Informative (+Free) Apps for Upping Your Nature Knowledge – Cool Green Science – These are great Apps to id plants and animals quickly…with cell phone: SEEK, iNaturalist, Merlin, eBird.

Gleanings of the Week Ending August 12, 2017

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.

Map of Play – A non-profit that not only builds playgrounds all over the US but also maps the ones they build and others (here). What a great way for families with children to explore the parks where they live….and when they travel!

Could a Bus with Sleep Pods Replace Airplanes? – Right now it only operates between LA and San Francisco…but it has the potential to be a less stressful way to travel than through an airport. What would it be like to take buses overnight and touring cities during the day…gradually moving cross country?

Top 25 Wild Bird Photographs of the Week #99 – Two pictures of peafowl! A male sitting with the tail feathers bunched behind and the head of a peahen!

The Chemistry of Giant Hogweed and how it causes skin burns – Awful plant! We were warned about this plant in Master Naturalist training since there have been some found in Maryland.

5 health benefits of beets – I’ve been enjoying beets from the CSA this year. Instead of always making fruit beety with them, I’ve be using them one at a time: raw in salads, in soups with potatoes (adds color!), and slivered for stir frying with other veggies. I like them well enough, I’ll buy them at the grocery store after the season for them via the CSA is over!

Illustrated timeline presents women’s fashion every year from 1784-1970 – A little history. I remember from the late 50s onwards and was making many of my own clothes from the mid-60s…so the styles for those years look familiar. I made a dress for myself that looked very similar to the 1966 dress about 1967!

The animals thriving in the Anthropocene – A study done by a team based near where I live in Maryland! Mosquitos, cockroaches, rats, deer, house sparrows…a few of the organisms are thriving while others are declining…or even becoming extinct.

Medieval Manuscripts are a DNA Smorgasbord – Much can be learned from the debris scraped away during cleaning of old manuscripts: DNA from bookworms and humans plus the animals that became parchment. So – we learn history from the physical aspects of manuscripts as much as well as from the words on the pages!

Magnificent Photos of Canyons Carved over Millions of Years –  Antelope Canyon and Canyon X…in Arizona. My husband already wants to plan a vacation to the place.

Ancient DNA used to track Mesa Verde exodus in 13^th century – Another item in the gleanings for this week about a place near Antelope Canyon…Mesa Verde. When I visited years ago, the mystery of where the people went was unresolved although many assumed they came part of the Pueblo peoples in New Mexico. This study used DNA of turkeys! Evidently the Mesa Verde people raised turkeys for feathers and food…and they took the turkeys with them when they migrated to the Northern Rio Grande area north of Santa Fe, NM.
