Why cats love to sit in boxes – even fake ones – All of our cats have liked sitting in boxes….it was fun to see some research showing that even the 2D shape is appealing to them!

An incomparable intellectual who fell through the cracks of history – A woman, of course. In this case it was Robert Boyle’s older sister, Katherine Jones, Lady Ranelagh.

Strange and surprising facts about Opossums – The only marsupial north of Mexico. Odd look and behavior.

Irish farmer stumbles onto ‘untouched’ ancient tomb – Turning over a rock and finding a stone-lined passageway!

Big Spring Lodge, Cabins Rehabilitation Lags at Ozark National Scenic Riverways – I hope the project now planned to start in the fall gets completed on time. The place would be a good vacation destination for us since my daughter lives in Missouri.

You are how you cook – Research on the cooking methods in different parts of China and the relationship to the type of grains utilized over time. The areas that boiled/steamed food tended to use millet over wheat or barley since the later two grains take longer to cook by that method.

Fighting dementia with play – A pilot study with a game consisting of a screen and floor panel with four fields that measure steps, weight displacement and balance….users attempt a sequence of movements with their feet requiring physical and mental skills. The pilot was promising. Perhaps these types of games will become one of the strategies to enable people to handle daily life longer.

Meet Benjamin Banneker, the black scientist who document brood x cicadas in the late 1700s – Benjamin Banneker Historical Park and Museum are close to where I live in Maryland. I’ve been there several times (posted about it in March 2015 and December 2018, but hadn’t realized that noting the periodic cicadas was one of his numerous observations.

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.

Gleanings of the Week Ending September 19, 2020

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.

Asphalt adds to air pollution, especially on hot, sunny days -- ScienceDaily – Evidently, it’s not just fresh asphalt that pollutes air. In cities, pollution from asphalt is significant enough that it needs to be considered in efforts to reduce pollution. Because it is usually dark in color it also contributes to the heat island effect in cities.

The Peopling of South America | The Scientist Magazine® - Sites along both coasts of the continent…analyzed with modern technologies…teasing out more information about the waves of migration.

The fate of antiques and heirlooms in a disposable age - BBC Future – As we come more conscious of the impact of our lifestyle on the environment….maybe durability of our possessions becomes more important again.

Researchers identify five types of cat owner -- ScienceDaily – In this study…the types are defined in terms of their attitudes toward their pets’ roaming and hunting: conscientious caretakers, concerned protectors, tolerant guardians, laissez-faire guardians, and freedom defenders. My husband and I are in the 1st category although there is a component of the second in our attitude as well. We keep our elderly cat indoors or on the screen enclosed deck.

Think Pigeons Are Boring? Not These Birds – From around the world.

How we sleep today may forecast when Alzheimer's disease begins -- ScienceDaily – The study indicates that the amount of deep sleep (i.e. non-REM slow-wave sleep) is predictive of how restorative sleep is for the brain (as measured by the build up (or not) of beta-amyloid plaques). They haven’t yet done the next step: improving sleep quality and observing the impact on beta-amyloid plaques.

Botanical gardens - where nature meets science and society – A short history of botanical gardens of Europe.

Some of America's favorite produce crops may need to get a move on by 2045 -- ScienceDaily – A third of veggies and two thirds of fruits/nuts consumed in the US are grown in California. In 20 years, climate change will make much of the area hotter and drier. The study looked at 5 crops (lettuce, broccoli, carrots, tomatoes, and cantaloupe) that make up 64% of California’s cash value of veggies/melons. In the future, cool season crops (like broccoli and lettuce) will be grown not just in fall and spring…but in the winter too. It will be too warm to continue growing tomatoes during the summer as that they are grown now and it could be challenging to find a 4 month period where the temperature is in a good range for tomatoes. The main message of the study is that planning needs to be done now to maintain food production in the US.

Eat, Prey, Love: Fast Facts on the Remarkable Praying Mantis – Mantises are fascinating insects. I listened to a video  recently about hummingbirds from one of the birding festivals that talked about mantises sometimes eating hummingbirds!

Playfulness can be trained - here's why you should do it -- ScienceDaily – Applying interventions of positive psychology to playfulness. It appeals to me that the study is coming out now when we have so many people in awkward situations trying to stay healthy. Increasing playfulness was found to improve mood!

Black Squirrel

We have lots for gray squirrels that come to our deck – trying to get seed from our feeder and water from the bird bath. Yesterday was the first time I’d seen a black squirrel there. Its the same species as the typical color squirrels. The black color means that both parents carried the recessive gene. I noticed that the pink color of the skin (ears, front paws, along the tail) was more noticeable because of the higher contrast with the fur color.

The first time I saw a black squirrel was in the mid-80s at Dumbarton Oaks. The tail looked scrawny and the squirrel seemed more aggressive. The tail on the one that came to our deck was about the same as the other squirrels around. It didn’t go all the way up to try it get seed out of the feeder but made a thorough search of the area below the feeder and got a drink at the bird bath before heading out. I wonder if we will see it again.

Unique activities for yesterday:

Rain in the bird baths. Rain showers came through – some quite heavy. But the sky was bright enough that I decided to photograph their impact on our birdbaths. The larger one among the day lilies just looked turbulent. The smaller one in the back was more interesting with the impacts of the rain drops on the water surface more defined.

Lots of cats. My daughter took a picture of this house in her neighborhood in Missouri as she took her daily walk. How many cats do you see? And they appear to be social distancing!
