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.

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.

US National Integrated Drought Information System – 68.4% of the US is abnormally dry…46% is in moderate drought…27% in severe drought. Use the location tab of this page to select state or county level maps color coded for their drought status. Where I live, we are in moderate drought.

Autumn in the Adirondacks – Leaf color has not been impacted by the drought in the Adirondacks. The pictures are from the Landsat 9 satellite. I’m enjoying the color from the ground – even with the drought here in Missouri making it not as colorful as it probably was in prior years.

Why cork is making a comeback – The main product mentioned in the article was cork stoppers….but I thought of the calm I felt when I walked into the University of Michigan’s Law Library with a tour group and realized how much the cork floor muffled our footsteps. It was the highpoint of the trip with my daughter when she was considering the school for her undergraduate studies.

Blue fibers found in dental calculus of Maya sacrifice victims – Analysis of more than 100 sacrifice victims found blue fibers in the mouths of 2 of them. Are the fibers from blue gags left in the mouths of victims over and extended time? Similar pigment called Maya blue has been found in other sites where it may have been used to paint the bodies of sacrificial victims. Another archeological mystery…

See the buzzworthy winners of the Wildlife Photographer of the Year competition – Eye candy for the week.

Millions of Americans are losing access to maternal care. Here’s what can be done – 36% of the counties nationwide – largely in the Midwest and South – constitute “maternity care deserts,” meaning they have no obstetric hospitals or birth centers and no obstetric providers. That does not bode well for the health of mothers and the next generation.

These stunning satellite images look like abstract art – and they reveal much about our planet – 8 images selected from US Geological Survey satellite images of the Earth’s surface.

Engineers weave advanced fabric that can cool a wearer down and warm them up – Maybe the ‘cool down’ of this technology (if it can be developed) will help us deal with climate change more effectively. There are already beginning to be more heat related deaths and there will be some occupations that will become impossible without technology to cool the body in outdoor environments.

Rainfall is becoming more intense in most of the US – East of the Rockies…there is increasing precipitation intensity. Water resource management is more challenging. Flooding risk is going up too.

USGS Public Lecture Series – A wide range of topics including volcanoes in Alaska, earthquake early warning for all, migratory big game, droughts and groundwater quality, modernizing the national water information system….and many more. I am beginning to work my way down this YouTube playlist.

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.

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.

Top 25 birds of the week: Forests! – Photographs and birds….always a great start to the gleanings list for the week.

Regulators Ban Fracking Permanently in the Four-State Delaware River Watershed - Yale E360 – The watershed provides drinking water to 13 million people in Pennsylvania, Delaware, New Jersey and New York….critical to not have toxic leaks into that supply….and the fracking industry does not have good track record when it comes to water quality.

Scientists stunned to discover plants beneath mile-deep Greenland ice -- ScienceDaily - Long-lost ice core provides direct evidence that giant ice sheet melted off within the last million years and is highly vulnerable to a warming climate.

The legendary fabric that no one knows how to make - BBC Future – Dhaka muslin…with thread counts up to 1,200.

Diphtheria risks becoming major global threat again as it evolves antimicrobial resistance -- ScienceDaily – Resistance to antibiotics and vaccine escape becoming more common/likely….not a good prospect.

Climate Change Lays Waste to Butterflies Across American West | Smart News | Smithsonian Magazine – The total number of observed butterflies west of the Rocky Mountains has fallen by 1.6 percent every year since 1977….that adds up to over 65% decrease!

Reflecting on your own capabilities boosts resilience -- ScienceDaily – Thinking about memories of successfully overcoming past challenges may help us cope with crisis situations we are facing in the present.

Great Lakes people among first coppersmiths | Science – The Old Copper Culture began earlier and faded earlier that previously thought…starting about 9,500 years ago and ending about 5,000 years ago. A climate shift might have caused the culture to shift from using copper for tools to adornment at the end of the period.

Waste from making purple corn chips yields a natural dye, supplements, kitty litter -- ScienceDaily – I like processes that dramatically reduce the amount of agricultural waste. I wonder if the purple kitty litter would stain carpet if it was tracked out of the litter box though.

Why cats won’t punish a stranger who harms you - BBC Future – Evidently cats do form emotional bonds with their humans…but they probably don’t pick up on human social relationships….not as domesticated as dogs.

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 September 21, 2019

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.

These Caterpillars Can Detect Color Using Their Skin, Not Their Eyes | Smart News | Smithsonian – A little surprise…but insects probably have a lot of adaptations developed over eons that are challenging to imagine.

Five weird and wonderful ways nature is being harnessed to build a sustainable fashion industry – New dyes from enzymes, ‘leather’ from mushrooms, lacy fabric made from plant roots that grew that way (watch the video), cellulose for fabrics derived from manure!

Aesthetics of skin cancer therapy may vary by treatment type -- ScienceDaily – Hopefully these findings will guide doctors to use the more aesthetic treatments…since they all have about the same recurrence rates a year after treatment.

On the Alabama Coast, the Unluckiest Island in America - Yale E360 – Dauphin Island…when does everyone decide that these places can’t be saved…should not be rebuilt. It’s not something we are dealing with very well as individuals or as a nation.

Deer browsing is not stopping the densification of Eastern US forests -- ScienceDaily – Deer hurt the understory but the canopy is more impacted by the greater density of the big forest trees (because of fire suppression) and that red maples are growing in areas where young oaks, hickories, or pines would have grown previously. But wouldn’t the deer browse young trees? In our area – the forests have also changed quite a lot in the last 20 years with the decline of the hemlocks and now the ashes. This study – done in Pennsylvania – did not comment about those issues.

Top 25 Wild Bird Photographs of the Week: September – These photographs are always worth a look….birds are so beautiful.

North America has lost 3 billion birds – And fresh from looking at the wonder pictures of birds….this sobering news: North America has lost 25% of its bird population and it’s all happened in the last 50 years. More than 90% of the loss is in just a dozen bird families that includes the sparrows, warblers, blackbirds, and finches. Grassland birds have suffered a 53% loss. Potential causes: habitat degradation, urbanization, and the use of toxic pesticides.

Staying at elementary school for longer associated with higher student attainment – My daughter didn’t seem to have a problem transferring from elementary to middle school after 5th grade…but the middle school was next door to the elementary school, and she was doing well in school. The results of this research will have to overcome the school building infrastructure in many areas. Change happens slowly with school systems. So far I haven’t seen a change in start times for high schools even though there are studies that say that early starts are not good for high school students (in our area, they have always started before the elementary and middle schools).

Spotted in Kenya: a baby zebra with polka dots – I hope there is a follow up story on this baby. Will the pattern make it more susceptible to fly bites? Another note from the article: Zebras are accepting of difference…animals with atypical coat patterns fit right into the herd.

Drought Reveals Lost “Spanish Stonehenge” – The Dolmen at Guadalperal has resurfaced from the Valdecanas Reservoir in western Spain due to lower lake levels from dry, hot conditions this year. It has been submerged for 50 years. Hopefully someone will make a good 3D tour of the place.

Macro Photography - Textiles

I am finally experimenting with my 60x macro lens that I got for my phone. Textiles around the house were an easy project. The lens has a light and I found it handy. With this lens, I use the zoom on the phone to avoid clipping the image to take out the vignetting around the edges. I’d rather compose the image in the camera.

I liked the simple weave and colors of the worn dishcloth.

20190314_114644.jpg

A crocheted hat had brilliant color but was not flat enough to focus well.

20190314_114655.jpg

The washcloth had more fuzzy fibers than I expected but

20190314_114829.jpg

Not nearly as many as the wool sock.

I got stuck on a tapestry jacket…had a challenge to choose just 3 to include in this post. The last one was from the inside of the jacket.

20190314_114948.jpg

The machine embroidery of a silk jacket looked very different than I anticipated.

20190314_115026.jpg

The weave of a light-weight jacket was more complex.

I realized that the patterns on t-shirts were painted – but hadn’t thought about what they would look like with the macro lens. The blobs of color stand out on the surface of the cotton knit.

20190314_115243.jpg

The most non-fuzzy fabric was microfiber underwear!

20190314_115315.jpg

The yarn in the bulky cardigan was almost too big to look interesting at this magnification.

20190314_115443.jpg

Machine-made borders look more orderly than the fabric sometimes (the black is thread).

20190314_115534.jpg

The eye detects tiny holes in the fabric of the bag for delicate fabrics to go in the washer; with macro lens, it looks like a Zentangle.

After I got back to my office, I looked at two mouse pads with the macro lens. One is a woven surface…the other looks like a paint.
