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.

Dragonflies Reveal Path of Mercury Pollution – Dragonfly larvae collected from 150 national parks and then analyzed for mercury revealed: in arid regions, mercury comes from snow and rain, while in wetter, more forested areas, airborne mercury clings to leaves, which then fall to the ground, where the toxin spreads.

Komodo dragons have iron-coated teeth to rip apart their prey – A clue to how dinosaurs like Tyrannosaurus rex killed and ate their prey.

COVID-19 devastated teacher morale − and it hasn’t recovered - A National Education Association survey of members found that, as of late 2022, a staggering 55% of educators were thinking of calling it quits because of: eroding sense of safety in the school, intense and unrelenting workload, lackluster leadership and changing expectations, and cuts in jobs and budget. Better pay is a start. I was disappointed that this article did not suggest more than that.

25 Stunning Images of the Cosmos from the Chandra X-Ray Observatory as It Celebrates 25 Years in Space - As NASA continues to grapple with a limited budget this year, Chandra is in danger of ending up on the agency’s chopping block and the program faces cuts in funding.

National Park Fun Facts: Petrified Forest – I’ve been to Petrified Forest National Park several times….still learned something from this post.

Art Bites: Michelangelo’s ‘David’ Was Carved Out of a Flawed Marble Slab – Some history of the famous statue.

8 Tips for Maximizing Your Home Solar Savings in 2024 – I am beginning to read articles like this…we will probably put solar on our house within the next year.

Why Covid-19 is spreading this summer – We’ve got to stop thinking about COVID as something that is like the flu…it isn’t.

Saving Dixie: 24 Hours Caring for a Wallaby Joey – The mother killed along a highway….and the Joey discovered alive…fortunately by someone who was willing to take care of him long enough to get him to an experienced wildlife carer.

Happy 50th birthday to the UPC barcode - While the world has changed a lot since the mid-1970s, the Universal Product Code (UPC) – what most people think of when they hear the word “barcode” – hasn’t. The code first scanned on a package of gum on June 26, 1974, is basically identical to the billions of barcodes scanned in stores all over the world today.

Filling a Day of Social Distance – 4/8/2020

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

Here are the unique activities for yesterday:

Hearing the phoebe first thing in the morning. I am hearing a phoebe outside my office window every morning as I begin my day. Maybe it’s in the sycamore. Maybe its nest is nearby. I know from the time that the sun has just come up this morning but the clouds are hiding it; it’s too dark too look for the bird and try to get a picture.

Cleaning off the covered deck furniture. With the temperature forecast to get into the 70s in the afternoon, I cleaned off the table and chairs on the covered deck in the morning so I could spend time there in the afternoon. Everything was very dusty since it hadn’t been used over the winter. The furniture is over 20 years old and had been on the covered deck since we got it. It is undercover but ‘outdoors’ and I noticed there are some bubbles in the paint on the metal parts. It probably needs to be sanded down, primed, and repainted…which I am not enthusiastic about attempting.

Walking the neighborhood. The forecast here is for cooler/wetter/windier after today so I wanted to get out and enjoy the sunshine…look around the neighborhood. Things change fast in the spring. Our cherry tree lost most of its petals overnight when thunderstorms rolled through. Most of the petals were on the ground. At another house the driveway was polka dotted with petals.

The azalea still just has buds (and the deer have browsed the bush so there are not very many buds left).

A neighbor has a deciduous magnolia in bloom and it held its flowers in the storm.

There is another tree blooming nearby. A fruit tree?

I recognized the redbud. ‘Cauliflory’ is a recent vocabulary word I learned from a tree tutorial; it means that the flowers are on branches and trunk…not where the leaf buds are…and that is how redbuds bloom!

There were several kinds of maples in various stages of producing seeds.

When I got to the pond, I noticed several flowers nearby (dandelions being everywhere but not always so thick as near the pond).

And then I looked more closely at the water retention pond itself. There were turtles! There were two large ones and one small. They were all Eastern Painted Turtles. The two big ones slipped into the water and then came back. The smaller one didn’t move except for the head and I noticed the scutes looked like they were peeling. Maybe they do that more when the turtle is growing up?

And there were robins just about everywhere.

Enjoying some outdoors-with-the-laptop-time. I tried standing at the table on the deck…that lasted for about 10 minutes…then I spent about an hour in one of the chairs. It was a great way to savor the spring day…listening to the birds (they came to the nearby bird feeder while I was there) and windchimes and breeze through the forest.

Catching up with the Cincinnati Zoo’s Home Safaris:

Gleanings of the Week Ending October 5, 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.

BBC - Future - The desert soil that could save lives – Bioprospecting for antibiotics and industrial biocatalysts from bacteria that survive in extreme environments like the Atacama or Antarctica

Top 25 Wild Bird Photographs of the Week: Resident Birds – National Geographic Society Newsroom – ‘Resident’ around the world….beautiful birds.

Global warming may threaten availability of essential brain-building fatty acid -- ScienceDaily – Impacts of climate change go far beyond the climate models…many probably still to be discovered.

Recovery: Restoring the Floodplain Forest – Cool Green Science – I started reading the article since I am always interested in how restoration projects are created and evolve…but the aspect I’ll remember about it was the info about a tree: American Elms. Ones resistant to Dutch Elm Disease are among the trees being planted as part of the restoration. I grew up at a time when the elms were all dying. There were several I remember at my grandparents’ house in Oklahoma and a tree beside the playhouse at the house we moved to in Dallas in the early 1970s. It was already sickly. I wonder if there will soon be enough varieties and availability of elm trees for them to become landscaping trees again.

Interview: Self-Taught Myanmar Photographer Captures People Working – Capturing images of human-made place. Now I am wondering what I would photograph in my part of the world to do something equivalent.

Crying over plant-based milk: neither science nor history favors a dairy monopoly – An article about milk….and the argument about what the word means. The dairy industry wants it to mean milk from cows…but milk has been used more broadly to mean white liquid for a very long time. We even have plants with ‘milk’ in their name (i.e. milkweed)!

Pictures of India's UNESCO World Heritage sites – Rich cultural and natural history…reflected in places selected to protect.

'Report card' on diet trends: Low-quality carbs account for 42 percent of a day's calories: Older people, those with lower income, and those with less education face greater hurdles -- ScienceDaily – With results like this, maybe we should come up with better ways of helping people learn about nutrition. Do our schools help students learn about nutrition? How many adults have logged their food intake into an app and discovered how good (or poor) their food choices are? The current outreach strategies relative to nutrition are not enough. Sometimes even doctors seem to lack any expertise other than knowing that a patient is overweight/obese or their waist is too large.

Create Wildlife Habitat Around Your House – Cool Green Science – I already have a bird bath and feeder, milkweed patch, brush pile and some native trees (maple, sycamore, tulip poplar, oak). Even a spongy compost pile is habitat (this summer I had puddling tiger swallowtails on it)!

Komodo Dragons Have Skin That Looks Like Chain Mail | Smart News | Smithsonian – Four distinct morphologies of osteoderms in the skin of adult Komodo dragons. Another example of the wonderful complexity in the natural world.
