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 Electric Revolution of Gardening Tools is Here – Hurray! We’ve been completely transitioned to battery powered yard tools for a few years now. I wouldn’t be mowing my own yard without our electric mower. Our old gas-powered one was noisy and my throat got scratchy from the fumes. Now I think of mowing the yard as a challenging exercise rather than a negative impact on my hearing and lungs!

US Cities Ranked by Vehicle Miles Traveled – As I read the article, I wondered where Dallas/Fort Worth fit since they were not on the top 10 list. I went to the source cited in the article and found that Dallas/Fort Worth was 19th.  Other Texas cities are high too – San Antonio at 14, Houston at 18 and Austin at 22.

See Frida Kahlo in Her Element in a New York Show of Rare Photographs – There is a picture of her (and Diego) viewing a solar eclipse in 1932 (Detroit)!

The apple detectives hunting for lost varieties - Apple fanatics across the UK are now taking samples from very old apple trees in hopes of learning more about antique varieties, and perhaps making some surprising discoveries. That's because there are apples, documented in 19th-Century books like Robert Hogg and Robert Bull Graves' The Herefordshire Pomona, that have slipped through people's fingers.

In North Macedonia, an Ancient Lake Faces Modern Threats – Lake Ohrid - 19 miles long, nine miles wide and 945 feet deep, teeming with fish, snails, leeches, flatworms, phytoplankton, crustaceans, and more. Of the lake’s roughly 1,200 known native species, 212 of them are endemic, occurring nowhere else. It faces growing threats, including from overfishing, nutrient pollution, invasive species, booming tourism, unregulated building, official neglect, and perhaps the most inexorable challenge of all, global warming.

Rare White Bison Calf Born at Yellowstone National Park - Photographed on June 4, as a group of bison crossed a road with traffic stopped.

A supermarket trip may soon look different, thanks to electronic shelf labels - This month, Walmart became the latest retailer to announce it’s replacing the price stickers in its aisles with electronic shelf labels. The new labels allow employees to change prices as often as every ten seconds. They haven’t come to the Walmart near me yet…I’ll be looking for them every time I shop there.

A new way to measure aging and disease risk with the protein aggregation clock - Although there are other "clocks" to measure ageing and health, most of them are based on nucleic acids like DNA. A biological clock based on proteins could be a useful complement to these existing clocks, as proteins are among the most abundant molecules in cells and are crucial for all cellular functions. With the help of such a protein aggregation clock, scientists and doctors might move one step closer towards helping people age healthily and preventing age-related diseases.

Tiny beauty: how I make scientific art from behind the microscope – Great illustrations…worth scrolling through.

New metric for blood circulation in brain to better understand dementia - By accurately measuring how pulsatility is transmitted in the brain, researchers can better understand the underlying mechanism of brain conditions (including Alzheimer’s disease and other forms of dementia) and potentially guide development of new treatments.

Gleanings of the Week Ending July 22, 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.

The ground is deforming, and buildings aren’t ready – Underground climate change in urban areas where heat islands underground cause enough expansions and contractions to damage building foundations…particularly in older buildings.

How noise pollution impacts nature – A study out of Vail, Colorado, showed that increased trail use by hikers and mountain bikers disturbed elk so much the cows birthed fewer calves. Another out of Grand Teton National Park showed that backcountry skiers scared bighorn sheep during winter when food was scarce, with potentially lethal consequences.

Hospital understaffing and poor work conditions associated with physician and nurse burnout and intent to leave - The study from the University of Pennsylvania School of Nursing found that physicians and nurses, even at hospitals known to be good places to work, experienced adverse outcomes during the pandemic and want hospital management to make significant improvements in their work environments and in patient safety. The solutions to high hospital clinician burnout and turnover, they say, are organizational improvements that provide safe workloads and better work-life balance NOT resilience training for clinicians to better cope with adverse working conditions.

The simple ways cities can adapt to heatwaves – Heat monitoring and planning is become more important for cities…the climate emergency in cities is a health emergency.

New biodegradable plastics are compostable in your backyard – New plastic made from blue-green cyanobacteria that isstronger and stiffer than previous plastics from the same raw ingredient. They can be recycled…but also degrade rapidly in the environment.

Giant Hand Axes Discovered in England Point to Prehistoric Humans’ ‘Strength and Skill’ – More than 300,000 years old perhaps from an interglacial period. Early Neanderthal people inhabited Britain then…and maybe other archaic human species too.

Germs, genes and soil: tales of pathogens past – DNA sequencers and powerful computational tools…applied to ancient microbes…probing their role in human history. This article describes how the work is done, ethical considerations…using examples of what has been accomplished so far. The field of archaeogenetics is just beginning.

Back from the Dead: New Hope for Resurrecting Extinct Plants – There is a global effort to digitize herbaria specimens which had helped identify holdings of extinct plants…sometimes finding seeds. And then the challenge is how to best attempt to grow old seeds.

Pain risk varies significantly across states – Pain due to arthritis varies geographically in the US – with the moderate to severe pain being 23% in West Virginia vs 7% in Minnesota.  There is also a difference between people that did not complete high school…and those who obtained at least a bachelor’s degree – with the delta being greatest in West Virginia, Arkansas, and Alabama. There is a need to focus on the macro-level policies (i.e. generally at the state level) while continuing current individual interventions.

The Acropolis Adopts Crowd Control Measures for the First Time – The post-pandemic travel surge is overwhelming at some places – including the Acropolis!

Unique Activities for Yesterday:

Clothes dryer working. Our 20-year-old clothes dryer has a new heating element and the dust/lint has been cleaned out from around the innards. The first loads we did were towels!

Doe and 2 fawns in our back yard. My husband noticed the deer in our back yard in the afternoon. They stayed around long enough for me to get some pictures. In past years we’ve had a doe and 2 fawns in our yard more frequently. This year their main path back into the forest must be through another yard because we haven’t seen them as often…and so it is a special day when we do.

The fawns are good size now, but their spots are still noticeable…not quite as well defined as earlier in the season.

Filling a Day of Social Distance – 4/21/2020 - Macro Fabrics

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

Here are the unique activities for yesterday:

Looking at Life Magazine for May 1944 – I found some early work of Chesley Bonestell that launched his space art career…mixed in with the coverage of World War II.

Finished reading Bruntsfield Brook by Charles Cockell. I bought the Kindle version after hearing about it in one of the Life in the Universe Pandemic Series videos. It was a fun way to learn about microbial mats…wound into a story with lots of drama impacting the different kinds of microbes: phages, ice, pollution, and drought.

Links to my previous “filling a day of social distance” posts  here.

And now for a little project prompted by learning (from Charles Cockell in his Life in the Universe Pandemic Series) that Antonie van Leeuvenhoek first used macro lenses to assess the quality of fabric…then turned the lenses onto other things and became known as ‘the father of microbiology.’ For some reason I had never thought about what prompted him to be using glass lenses originally. So – I did a little project to look at different fabrics with the jeweler’s loupe…taking pictures with my phone through the loupe.

I started with the upholstery fabric on a couch. The colors are more vivid when they are magnified! I don’t know what the fiber content is…but it’s shiny…. that probably means it’s synthetic.

Clothes that I had that were labelled 100% cotton were all tops. 2 t-shirts (normal weight and thin) and a waffle shirt

I also had an older 100% cotton denim shirt. It is old enough to have some worn areas.

Then there were the cotton and polyester blends. The bandana didn’t have a label, but I lumped it with the blends because it was shiny. A pair of jeans and a t-shirt looked like cotton so I assume that the polyester part might be wrapped in cotton.

A quilted jacked had a looser weave and was shiny. A man’s shirt and my photovest were both a tight weave cotton/polyester.

I have a linen-look button front tunic that I have enjoyed wearing for years. I didn’t realize it was 100% polyester until I looked at the label. And it looks very much like plastic when magnified! I’d never thought of it as ‘shiny’ before.

I had two silk scarves which I included in my pile to photograph.

And then there was acrylic blended with polyester (for a cardigan), with cotton (for a ribbed turtleneck) and nylon for a lightweight unlined sweater jacket. The last one looks like the 100% polyester tunic – although the fiber in the tunic is woven and the sweater jacket is a knit.

Overall – it was an interesting project. I am always keen to apply what I am learning, and this project blended the astrobiology lectures and the Fashion as Design class!
