Gleanings of the Week Ending May 7, 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.

A Watershed Moment: Key Findings About Potential Drinking Water Contamination – The sources of contamination are varied….but the list of primary sources is relatively short.

Better residents’ health after switch to electric buses – A study from Sweden. Improved health is a benefit of electrification of transportation!

Should people get rid of their yards? – Somewhat depressing conclusion: “Most people would rather make an aesthetic choice with their lawns than an environmental one.” My plan is not to eliminate the yard in my new house but to minimize it over time with the addition of bushes along the fence and extending beds around trees and around the house.

We talk the fastest growing green jobs with LinkedIn Sr. Editor – The “job vs the environment” is changing. The “green economy’s ability to expand job opportunities is too significant to ignore.” This growth in green jobs is like the 1970s for computer related jobs – a lot of new types of jobs and many of them will extend for the duration of a career starting now.

Discover the Microscopic Wonders of Olympus’ 2021 Image of the Year Awards – Taken with light microscopes…lots of finesse preparing the specimens.

Known to be toxic for a century, lead still poisons thousands of Midwestern kids – Two things I learned from this article about the state I am moving to: Missouri is one of the four states in the Midwest that is struggling to alleviate lead poisoning in children…and it is the number one producer of lead in the US. Hope they are making progress.

Top 25 birds of the week: terrestrial birds – Always enjoy the bird photographs! This group includes a roadrunner….a bird I always associate with Texas but the photograph was taken in California!

Tests indicate bronze age daggers had a practical purpose – Evidently the daggers were thought to be ceremonial objects prior to this analysis.

Should we be eating three meals a day? – The number of meals may not be as important as consistency….and giving the body a long enough ‘fast’ time to rest.

The Great Barrier Reef through Time – Landsat Images used to illustrate recent research on the growth of the reefs as the ocean changes. Evidently the reef has been more resilient to past sea-level and temperature fluctuations than previously thought….but increased sediment input has been a bigger problem.

Mycology Class Remnants

Way back in the 1970s when I was working on my undergraduate degree in Biology, I took a mycology (study of fungi) class. It was one of the most memorable upper level courses in my undergraduate work…but it’s been a long time. The textbook, lab book and spiral notebooks are long gone. When I was cleaning out the basement (continuing projects during the ‘stay at home as much as possible’ strategy to avoid COVID-19), I found remnants of the course: some black and white negatives in protective sleeves – unlabeled. As soon as I looked at them, I knew they were microphotographs of the microscope slides I made during the mycology lab even though I don’t remember which species they are (some are penicillium species).

The negatives were somewhat deteriorated – maybe they were never crisply focused. I scanned them with my Epson V600 Photo Scanner then clipped the best portions of some of the frames and colored them blue in Microsoft Powerpoint. They have an abstract art look.

I remember that in the lab we inoculated growth medium (agar and other types), let the fungus grow onto the glass…then stained the fungus (methylene blue, I think) to make the filaments and fruiting structures and spores appear blue under the microscope. I would love to take a mycology lab course again….and take lots of pictures!

4 Free eBooks – July 2018

Last month I have 4 eBooks to highlight and the same is true for this months – so I gave up and changed the title from 3 to 4. I had a lot of books to choose from…went for a bit of variety.

Yōfu gajō (v. 1). Kyōto-shi: Yamada Unsōdō. Published originally in the Meiji period, 1868-1912. Available from Smithsonian Libraries here.  I liked the scenery in this volume – muted colors except for the red that pops. In the image below – do you think it is a Japanese maple? This was one of the last books in the collection of Japanese books available from this site; if you want to take a look at the whole collection – do so from the Japanese Illustrated Books from the Edo And Meiji Period page.

Andō, Hiroshige. Tokaido gojusantsugi. Published originally in the Edo Period, 1600-1868. Available from Smithsonian Libraries here. I couldn’t resist two images from this book – rain and snow. I think the snow is my favorite because of the pink….maybe sunrise?

Catlow, Agnes. Drops of water : their marvelous and beautiful inhabitants displayed by the microscope. London: Reeve and Benham. 1851. Available from Internet Archive here. The book was published just before or early in the Victorian surge in microscopy and became one of her most successful books. She was also one of the early science writers that wrote science books for young students.

The Craftsman. New York: United Crafts. A magazine founded and edited by the American furniture designer Gustav Stickley and published from October 1901 to December 1916. All issues are available from the University of Wisconsin Library’s Digital Library for the Decorative Arts and Material Culture here. I am working my way through the issues a year at a time. I’m up to 1907 as of yesterday.

There are lots of ideas that would work in modern situations….like hanging curtains far enough away from a window to allow chairs to be in front of the windows without having any curtains at all in the way of the light. I can imagine sitting in the chairs on a sunny winter day with sun streaming in…closing the curtains so that the area gets cozy warm…reading or writing on my laptop or creating a Zentangle.

Foldscope Adventure - 1

I participated in the Foldscope Kickstarter and got foldscopes in the thick of volunteering and traveling activities last fall. The instructions on how to put the pieces together were a little daunting; it took me a month to discover that there were videos that made the process a lot easier to understand.

I managed to put one together and

Took a few pictures with my phone of one of the sample slides that came in the kit using the attachment for smartphones included in the kit (I had to take the case off my phone which means I will collect several samples and then do photography all at once – and not in the field).

Now I am carrying around a small vial and will collect some stream water at the next opportunity…and will look at other ‘micro’ stuff as I go along…stay tuned.
