Gleanings of the Week Ending February 18, 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.

Farmers Find Wild African Cat Wandering Around Missouri – A serval found when a farming family set a live trap to capture the culprit leaving bones and feathers between their stacks of hay bales! The Turpentine Creek Wildlife Refuge came to the rescue. This is all close to where I live and I was saddened that evidently the new Big Cat Public Safety Act does not include the smaller non-native wild cats…and that someone was cruel enough to release this cat of the African savanna into the wild in Missouri.

Caribou have been using the same Arctic calving grounds for 3,000 years – Analysis of antlers found on the tundra….discovering some of them are 3,000 years old! But the Arctic is warming faster than other parts of the globe. The elders of the village south of the calving grounds comment that they have noticed a lot more trees, less barren tundra. What will happen to the barren ground caribou as this habitat gets converted to forest?

Why fabric fraud is easy to hide – The fashion supply chain is fragmented and very dense….most apparel companies do not track their own supply chain (or don’t go past their immediate suppliers). Organic cotton is one of the prime examples of how end products labelled as organic cotton…might not be. It is hard to determine where the fraud is inserted in the process; the result is that the consumer is paying a premium price…not getting what they are paying for. And to improve the system will require big changes in the fabric/apparel business.

A Field Guide to Unexpected, Out-of-Place Wildlife – Sometimes animals have ranges that are changing or are a lot larger than we anticipate…sometimes birds are in very different places that their usual range!

Dirty Laundry: How much microfiber do we emit with our laundry – A study done in the UK…but probably relevant to the US as well. Microfibers from laundry in the UK weigh 6,850 to 17,847 tons per year. Yes…that’s a lot and pollutes water…however, it is a dwarfed by the 365,000 tons of clothing going into UK landfills per year.

Antibiotic use in farming set to soar despite drug-resistance fears – The increase in bacterial infections that cannot be treated with antibiotics (because of bacteria developing resistance to antibiotics) has been growing in recent years. Overuse of antibiotivs in agriculture is thought to be a major driver of the problem. Governments around the world have attempted to curb the use of antibiotics to promote growth but the use is still expected to grow by 8% between 2020 and 2030. The article includes a chart of agricultural antibiotics by country in 2020…and a projection for 2030.

The Lifelike Glass Models of Leopold and Rudolf Blaschka – Thousands of realistic models of plants and sea creatures made by a father and son from the 1860s until 1938.

8 everyday foods you might not realize are ultra-processed – and how to spot them – I am cutting back on ultra-processed foods this year. Some of the 8 listed in this article are easy: I don’t eat breakfast cereals, I only eat protein bars as ‘emergency rations’ (i.e. not frequently) and avoid yogurt, meal bases and sauces, processed meats, and margarine. I’m still looking for a soy milk that has fewer ingredients; will give up on soy milk soon if I don’t find one. And I try to buy bakery bread.

Did Philip II bring invasive fish to Spain? – Evidently his efforts to acquire fish and crayfish from afar spanned at least 25 years!

Study reveals that much still not known about cognitive decline - Data came from 7,068 participants in the 1996-2016 Health and Retirement Study. Participants were born between 1931 and 1941. Researchers measured their cognitive functioning at age 54 and how it declined until they were 85. At age 54, socioeconomic status, education and race -- explained only 38% of the variation in functioning. Those same factors explained only 5.6% of the variation in how quickly cognitive functioning declined in people between age 54 and 85. So much we don’t know about cognitive decline although it is pervasive in older adults, even those without dementia.

Designs of Kyoto: a collection of design for silk and cotton textiles

The two volumes of Designs of Kyoto: a collection of designs for silk and cotton textiles (volume 1 and volume 2) were published in 1906 and are available on Internet Archive. I’ve selected 2 sample images from both volumes.

I enjoyed the books – lots of nature themes and ideas for Zentangle patterns. Some of them looked very abstract – geometric – hits of realism. There is a modern quality to many even though they are more than 100 years old. Maybe nature images are timeless as long as the animal/plant depicted still exists in our world.

Silk and cotton are luxuries now – the inexpensive fabrics are synthetic creating a lot of ‘fast fashion’ with interesting fabric patterns….like these.

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!

Gleanings of the Week Ending November 17, 2018

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.

1.8 Million Clean Energy Workers Employed in Top 50 American Metro Areas | CleanTechnica – Jobs that are future leaning rather than in anchor industries like fossil fuels.

USDA Approves Edible Cotton | The Scientist Magazine® - Edible? I wonder if many people will have digestive problems with the seeds even if they are approved for human consumption.

The rise of sponges in Anthropocene reef ecosystems – Coral is impacted by higher temperatures and acidification more than sponges and there are already some ‘reefs’ that are dominated by sponges rather than coral. These reefs function differently and are expected to become more prevalent.

Study explores infant body position and learning -- ScienceDaily – I am always fascinated about studies with babies…observational but trying to be objective.

$31 Billion Hurricane Protection Plan Proposed for Texas - News | Planetizen – A hefty price tag…and who will pay for it? Would it work for very much of the area if they had another Hurricane like Harvey?

A Day in The Park: Hot Springs National Park – I visited this park years ago…before many of the more recent renovations. Maybe it’s time to see visit again.

'Wildlife Photographer of the Year' awards: Here are the best animal photos of 2018 – Great photography…nature…art. My favorite was the last one – the treehopper guarding her family.

Passive Radiative Cooling Moves Out of The Lab & Into the Real World | CleanTechnica – Cooling without consuming massive amounts of electricity….but is it really ‘out of the lab’ yet.

The Armchair Photography Guide to Bryce Canyon National Park – Part 2, Inspiration Point to Rainbow Point – There seem to be several articles in my feeds that are prompting thought of future travel. This is another place I’d like to go. The last time I was in Utah, the Federal government was closed so the national parks were not open!

Infographic: Exercise’s Effects on the Brain – Understanding the molecular mechanisms that connect exercise to cognitive benefits.
