March 27, 2021/ Gwen Morrison

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.

Alexander Calder – Modern from the Start – An exhibit at The Museum of Modern Art (MoMA). There are pictures and a videos of the exhibit on the site. I watched the webinar on the 25th when it was live and am in the process of looking at the rest of the site now.

Doug Tallamy’s List of Best Plant Genera for Supporting Moths and Butterflies | pollinator-pathway – Arbor Day is coming up in most areas (it varies by state depending on the best tree planting time. If you are thinking about planting a tree (or trees), think native and ones that support moths and butterflies!

Top 25 birds of the week: Bird Colours! - Wild Bird Revolution and Top 25 birds of the week: Bird Communication! - Wild Bird Revolution – Enjoy a double dose of bird photographs this week.

New skin patch brings us closer to wearable, all-in-one health monitor -- ScienceDaily – Still in the research phase…but a step forward. I like the idea of a blood pressure measurement that can be linked with other data throughout the day.

Is the Western way of raising kids weird? - BBC Future – We tend to think that the cultural norms we grow up in are the ‘best’ – but that may not always be true.

On U.S. East Coast, Has Offshore Wind’s Moment Finally Arrived? - Yale E360 – Reliable source of wind and proximity to populous markets….maybe the false starts are finally in the past for this renewal source of energy.

10 virtual tours of spectacular buildings around the world | Top 10s | The Guardian – More places to visit virtually!

Slideshow: Watch Insects in Motion | The Scientist Magazine® - Some technologies researchers are applying to better understand how insects have become such successful fliers.

How the Loss of Soil Is Sacrificing America’s Natural Heritage - Yale E360 – At best 24% of Corn Belt topsoil is gone…at worst 46%....and topsoil is still being lost. The study found that the main source of erosion is not water runoff but tillage…and right now only 15% of acreage in the heart of the Corn Belt is ‘no-till.’

Oldest Known Wild Bird Hatches Chick at Age 70 | Smart News | Smithsonian Magazine – Wisdom, an Laysan albatross, returns to Midway Atoll again. Her chick for this year hatched on February 1. She has outlived the person that originally banded her!

Filling a Day of Social Distance – 4/28/2020 – Little Celebrations

April 29, 2020/ Gwen Morrison

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

Here are the unique activities for yesterday:

**Making echinoderm prompted Zentangle**® tiles. *Jurassic echinoderms France* is full of plates and worth browsing; it’s available on Internet Archive here. Four sample images are below. I’ve only made one Zentangle so far but I’m sure the patterns will pop up in the tiles I make over the next few days.

Starting the What is Contemporary Art? Coursera course. It is my 3rd class from MoMA. For some reason – I am interested in classes that are different from my typical science or history classes I’ve taken in non-pandemic years.

Watching a Glenn Randall Photography webinar on light for landscape photographers. It was something my husband found out about and set up for us. We watched on the television in the den. Now I have some vocabulary for some of the type of light I enjoy early or late in the day! I realized that some of the wonderful light on the sandhill cranes in the early mornings at Bosque del Apache is ‘glow light’ from the sun 20 minutes away from coming up behind us.

Making sweet potato custard. Probably my favorite food creation during our ‘stay at home as much as possible’ time has been sweet potato custard. This is the second time I’ve made it. I cook the sweet potato in the oven when we are baking something else…then peel it and save it in the refrigerator until I’m ready to make the custard. The sweet potato goes into the Ninja food processor with 4 eggs, 1 teaspoon cinnamon, 1/2 teaspoon ginger, 1/4 teaspoon cloves and 1/2 to 3/4 cup sugar (this time I was trying to use up some powdered sugar so I used the higher amount). After processing and scrapping down the sides, I add in enough almond milk to make the consistency about right….processing again to get it thoroughly blended. After pouring it into the backing dish, I cover the top with chopped pecans. It cooks for 15 minutes at 425 degrees and 30 minutes at 350 degrees.

It never lasts long since both my husband and I like it a lot.

And now for the monthly post about 10 little celebrations. Again – the overwhelming celebration (the same as in March) is that in April 2020

Everyone in my family (in Maryland, Missouri, and Texas) is well…and taking all the recommended precautions to stay that way.

Now for 9 other celebrations….all from home (or easy walking distance):

Talking to family far away. It’s such a boost to talk with family – know that they are doing fine – that we all have pleasant homes and a few people with us. It’s good to let whatever anxiety has accumulated to melt away and celebrate family.

Grocery delivery. At first the idea of grocery delivery made me anxious. Now I find that the arrival of another delivery to our front porch is a cause for celebration. We have good food at low health risk.

Fashion as Design Coursera course. The whole course was interesting. I learned a lot more – and maybe differently – that I anticipated. I celebrated the whole course.

My history in wardrobe terms. The Fashion as Design prompted a whole project - thinking about my wardrobe from the 1960s to today. It was a fun project and I celebrated the memory of my favorite clothes.

Life in the Universe Pandemic Series. I’m a fan of Charles Cockell’s mini-lectures on astrobiology and I enjoyed his book (Bruntsfield Brook) as well. I watch/listen to the videos in clumps…glad I became aware of them shortly after he started.

Hiking into the forest. The whole hike was one big celebration. I am already looking at the forecast and planning another hike.

And then there are three birds I am highlighting as April celebrations: rose-breasted grosbeak, piliated woodpecker, and goldfinch. I celebrate the view from my office window each and every day. It is becoming a wall of green now that the trees are leafing out.

The Zentangle® Method is an easy-to-learn, relaxing, and fun way to create beautiful images by drawing structured patterns. It was created by Rick Roberts and Maria Thomas. "Zentangle" is a registered trademark of Zentangle, Inc. Learn more at zentangle.com.

Filling a Day of Social Distance – 4/24/2020 - Gleanings

April 25, 2020/ Gwen Morrison

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

Here are the unique activities for yesterday:

Finishing Fashion as Design Coursera course. The theme for the last module was Expression. It was a good way to end the course. I have enjoyed both courses I’ve done from MoMA and will probably start a third one – What is Contemporary Art – early next week.

Hearing a piano practice. My husband opted to start up piano practice…not sure why he hadn’t thought to play it weeks ago. What’s not to like about a grand piano? It was tuned last winter just before the coronavirus pandemic, so it is in excellent condition. His playing didn’t last for long, because the cat demanded attention…and has decided that the best place to sleep is under the piano.

And then there are the gleanings for the past week:

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.

How Rain Evolved Its Distinct Scent—and Why Animals and Humans Love It | Smart News | Smithsonian Magazine – The chemical that is the scent of newly moistened soil, geosmin, has been known to scientists since the 1960s….but now we are figuring out its purpose. It is made by 120 of 122 species of bacteria in the genus Streptomyces that have been studied. The scent attracts springtails (tiny arthropods) that eat the bacteria and spread the bacteria’s spores via their excrement or the spores that attach to their body and then fall off. Many other insects, fungi and nematodes are killed by chemicals produced by the bacteria. So – the scent after rain is connected to the lifecycle of bacteria that are one of the most important sources of antibiotics known to science!

Top 25 birds of the week: Terrestrial Birds - Wild Bird Revolution – Enjoying images of birds from around the world.

Long-living tropical trees play outsized role in carbon storage -- ScienceDaily – They used ‘hindcasting’ to validate their model: seeded the model with forest composition data collected at their site in Panama during the 1980s and then ran the model forward to see that it adequately represents the changes that occurred from then until now. Once that was done…they can use the model to predict what will happen to the forest with climate change. Will the forest continue absorbing some of the excess carbon – or not?

Flamingos in Captivity Pick Favorite Friends Among the Flock | Smart News | Smithsonian Magazine – 2-4 birds…not limited to mated pairs. Some were together for the whole 5 years of the study! The study found no loners but some bounded between groups.

What do soap bubbles and butterflies have in common? Butterfly breeding gives insight into evolution of iridescence -- ScienceDaily – A 75% increase thickness in the chitin lamina of wing scales turned iridescent gold to shiny blue….the same way a soap bubble iridescence works! And now there is a whole new genetic approach to investigate structural color in butterflies – and may lead to new ways to produce photonic nanostructures for solar panels, paints, clothing, and cosmetics.

How to mine precious metals in your home - BBC Future – Theoretically - the “urban mine” is far richer in high value materials per ton than traditional metal ore mines….but we don’t quite have the way to collect the ‘ore’ or effectively extract the metals.

Springfield Plateau: Cowbird Eggs – Cowbirds….I’m trying not to be too judgmental. (I’ve included a picture of cowbirds at our bird feeder below. The female is a more frequent visitor than the male.)

Colorful Image Lights Up Microscopic Guts of 'Water Bear' | Smart News | Smithsonian Magazine – Enhancing our view of a tardigrade with fluorescent stain….and done close to where I live at University of Maryland Baltimore County!

Take a Free Virtual Tour of Five Egyptian Heritage Sites | Smart News | Smithsonian Magazine – These are best viewed on your largest monitor!

Common protein in skin can 'turn on' allergic itch -- ScienceDaily – Turning off the production of the protein periostin in the skin can reduce the itch from atopic dermatitis (in mice). More research needed to see if it works for humans too.
