Gleanings of the Week Ending April 8, 2023

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.

Avi Kwa Ame, Sacred Land in Nevada, to Be Preserved as a National Monument – Good! Another place to see when we make a trip in the west.

Volvo Delivers Its 1st Electric Heavy-Duty Truck in Africa – The truck is being used for collecting waste in Rabat, Morocco. Morocco is also home to the world’s biggest concentrated solar power facility.

A 90-year-old tortoise named Mr. Pickles just became a father of 3. It's a big 'dill' – Radiated tortoise native to Madagascar and critically endangered…at the Houston Zoo.

One of Europe’s last free-flowing rivers declared a National Park – Albania’s Vjosa River. Europe is also removing dams along other river just as we are in the US…but rivers that have been controlled by barriers will never be the way they were before the dam.

Clinics on wheels bring doctors and dentists to health care deserts – It’s a step forward and might work well for preventative or chronic care…but what happens in cases where the need is more urgent…like broken bones, having a baby, the aftermath of a car accident?

Technology over the long run: zoom out to see how dramatically the world can change within a lifetime – A graphic from ‘Our World in Data’ – worth the look. See the big developments they selected occuring during your lifetime….and when technologies we take for granted came along.

Take a Virtual Tour of the ‘Doomsday’ Seed Vault – Its doors are only opened a few times each year for new seed entries. The seeds come from countries from all over the world and are kept at -18 degrees Celsius. The most recent withdrawal was to re-establish a seedbank that had been destroyed in Aleppo during the Syrian Civil War.

Urban Trees Could Cut Summer Heat Deaths by a Third – Increasing tree cover to 30% could reduce premature deaths from urban heat islands by 40%. Sounds like a good idea of heath…and makes the cities more appealing too. Other actions can help too: green roofs/walls, light colored roofs/walls/landscape pavers, and replacing impervious surfaces with plants and soils.

Fresh produce contaminated with toxic BPA-like chemicals found in food labels – A Canadian study found that the chemicals migrate from labels in packaging materials into the food!

Common sweetener suppresses mouse immune system — in high doses – An artificial sweetener (sucralose) that might become a drug to reduce or replace immunosuppressive drugs that often have a lot of unpleasant side effects (if humans react to it the same as mice).

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.

Study recommends six steps to improve our water quality – The study focused on nitrogen pollution.

The cells that give you super-immunity – Memory B cells were first discovered in the 1960s….but there is still a lot we are learning about them as we analyze the data from the COVID-19 pandemic.

Chicken Frenzy: A State Awash in Hog Farms Faces a Poultry Boom – Ugh! Hope North Carolina can figure out how to keep their groundwater and waterways from being polluted. It’s a beautiful state and it saddens me that the intensive hog and poultry production has not developed technology to be friendly to their immediate environment….or any place that is down stream from where they are located.

What’s the Weirdest Animal Courtship? Here Are 4 Candidates – A post that came out on Valentine’s Day.

Heart-disease risk soars after COVID – even with a mild case – Heart disease was already one of the chronic conditions common for a lot of people in later life… now with COVID, the numbers of people are going to increase and the age demographics are skewing younger.

Enhanced forensic test confirms Neolithic fisherman died by drowning – A skeleton from a 5,000-year-old mass grave on the coast of Northern Chile was analyzed with methods used for more recent bones to determine if a person drowned in salt water….and the method worked!

The mysteries of the Ponderosa Pine – The complex relationships between the health of pine forests and: birds, low-severity fire, squirrels, mushrooms, and carbon storage. Forests are complex!

The science of healthy baby sleep - A little history…and the bottom line: there is NOT just one correct approach to how infants should sleep.

Feeling dizzy when you stand up? Simple muscle techniques can effectively manage symptoms of initial orthostatic hypotension – There might be more validation that needs to be done across a wider demographic range…..hope this happens and if it works for a wide range of people so that doctors can immediately start encouraging their patients that have initial orthostatic hypertension (IOH) to use the simple moves before and immediately after they stand up.

Do you know the world weirdest wild pigs? – The post includes 5 of the 18 wild pig species. The only one in North America is the Africa Red River Hog – one was caught in a trap set for feral hog control in Texas (2019); there are evidently Texas game ranches advertising ‘hunts’ for red river hogs which indicates they have been intentionally imported and there has been at least one escapee from one of those ranches! Is there a free-ranging population of African River Hogs reproducing in the wilds of Texas?

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.

Porcupines | National Geographic – I was disappointed that they didn’t include more pictures of the North American Porcupine. I’ve never seen one in the wild.

BBC - Future - How to build something that lasts 10,000 years – Specifically – this post is about building a clock that will last for 10,000 years…in West Texas!

Researchers uncover indoor pollution hazards -- ScienceDaily – Some surprises: pollutants change with temperature inside the house….and time of day makes a difference. Formaldehyde seems to be particularly prevalent. These studies are scary for existing homes. We need work on mitigations that homeowners can implement…and new construction that reduces the source of pollutants.

Infographic: Immunity Isn't the Body's Only Defense System | The Scientist Magazine® - Symbiotic bacteria, metabolism and pathogen mutation examples overlay the immunity strategy. As we learn more, we realize that the human body is more complex that we realized.

Top 25 Wild Bird Photographs of the Week: Blue – National Geographic Society Newsroom – So many blue birds!

Tortoises rule on Aldabra Atoll – Tortoises making their way through the huts where people bunked! The tortoises sleep with head and legs stretched out…no predators to fear on the inhospitable atoll.

Past climate change pushed birds from the northern hemisphere to the tropics -- ScienceDaily – Thought provoking. I wondered if some of the birds that now migrate from North America to Central or South America for the winter….will not go as far or will shift their range northward.  I suppose it would work if their food sources shifted and the birds followed the food. The synchrony of plants blooming and seeds ripening….of horseshoe crabs laying eggs…all while birds are migrating or getting ready to produce young; it’s not a simple system.

Making STEM Education More Welcoming to Underrepresented Minorities | The Scientist Magazine® - Education doesn’t happen in a vacuum that has well defined boundaries. We must do more than just academic support…I’m glad there is more research and conversation on how to move forward in tangible ways to make STEM education and careers more open to everyone.

An Ancient Asteroid Crater May Be Hiding Off Scotland’s Coast | Smart News | Smithsonian – Some recent work that points to a crater of a asteroid from 1.2 billion years ago.

Three Studies Track People's Microbiomes Through Health and Disease | The Scientist Magazine® - Interesting…but they could just be expensive association studies (a quote from the end of the paper). At some point, maybe the findings will lead to something that benefits the patient.
