Gleanings of the Week Ending August 26, 2017

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 Wild Bird Photographs of the Week #101 and #102 – 50 bird pictures this week! My favorite in the first group is the barn owl (and the other owls in this group). My favorite in the second group are the two pictures of spotted owlets! --- I am drawn to owls this week for some reason.

Voyager: Inside the world’s greatest space mission – The two Voyager space craft were launched in 1977…and are both sending back messages to earth.

Trees with ‘crown shyness’ mysteriously avoid touching each other – I haven’t observed this phenomenon in our Maryland forests…but now when I am in a forest, I’ll always look for it!

Time Spent – Who Americans spend their time with (from Richard Watson’s blog). It changes with age. The last chart shows that as we get older we spend more and more time alone.

Air pollutions ranking in 32 cities –  LA ranks 24; Washington DC, San Francisco and New York are 26-28; Boston is 31. Delhi, Beijing, and Cairo are the top three.

Trees and shrubs offer new food crops to diversity the farm – Ongoing research from the University of Illinois trying to mimic the habitat features, carbon storage, and nutrient-holding capacities of a natural system with a farming method that incorporates berry and nut bearing shrubs/trees with alley cropping (hay or row crops)….to be economically and environmentally sound.

AWEA releases map of every wind farm and factory in America – There is a link to the interactive map. The red diamonds are manufactures and the blue dots are the wind farms themselves. It’s easy to see that manufactures happens a lot in areas other than where the wind farms are located….that the center of the country has a lot of installed wind turbines! We saw some of them in Iowa on our way to and from the solar eclipse last Monday.

Diversity Lacking in US Academia: Study – Under-representation of African Americans, Hispanics, and women in STEM faculties at public universities. There is a similar lack of diversity in PhD programs. On a positive note: the assistant professor is more diverse (more Asians, Hispanics and women) that the associate or full professor rank.  Unfortunately, this positive finding is not true for African Americans. Overall – still a challenge….and it impacts the broader labor market as well.

More than 300,000 Atlantic Salmon Spill into Pacific – Oh no! Hopefully this is not catastrophic in the long run. But – Why are they growing Atlantic salmon in pens in Puget Sound anyway?

Thanks to Co-op, Small Iowa Town Goes Big on Solar – Kalona, Iowa – not far from our route to the eclipse! It comes down to local self-reliance and economic development that made sense for this small town. Somehow a pointer to this article (from last February) was in a blog post I looked at when I returned home and I noticed where the town was…small world.

Gleanings of the Week Ending August 19, 2017

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.

Three things to know about the Louvre’s history – A fort…royal residence…and then a museum!

Americans are using less electricity today than a decade ago – Annual residential electricity sales have declined by 3% and residential electricity sales per capita is down by 7% since 2010. Advances in efficiency and shifts to smaller devices are making a difference. Some argue that electric cars will cause an increase in demand for electricity….but the same people that drive electric cars are likely to have solar panels!

Aspirin’s Four-Thousand-Year History – Willow bark was used for 1000s of years for ‘curing’ fevers. In 1897, Felix Hoffman at Bayer created chemically pure salicylic acid and then created acetylsalicylic acid which did not irritate digestion the way salicylic acid does….and Aspirin came to the marketplace.

The Quest to Restore American Elms: Nearing the Finish Line – My grandparents had elm trees around their house in Oklahoma when I was growing up in the ‘60s. My grandfather built a picnic table around one of them and we had our evening meals there during our summer visits. In my late teens, the tree began to die and eventually had to be cut down. The place lost a key element when that happened. I’m sure that was true around many homes. I hope the elms can be restored….and maybe the chestnuts too.

Climate change is disrupting the birds and the bees and Europe to experience vast and rapid ‘invasion’ by infectious diseases as climate warming continues – The effects of climate change are not just rising temperatures or changing weather patterns. Everything on earth is interrelated. Sometimes that building in resiliency to change and sometimes it enables small changes to have a domino effect that is catastrophic.

In the Earth’s hottest place, life has been found in pure acid – Microbes that survive in extreme acid, hot temperatures, and high salinity. The pH in one pool was 0…and life was found there.

Here’s a crazy idea: let’s agree on the facts – Finding common ground through data? That is what Steve Ballmer is working on. The USAFacts site is the result and it is very easy to spend time looking at the summary reports….and the linkage to raw data sources.

It’s not your imagination. Summers are getting hotter. – A graphic of the changing bell curve of the temperatures with the base period being 1950-1980…crawling toward the hot and hotter direction for the time periods since them.

Top 25 Wild Bird Photographs of the Week #100 – There is an indigo bunting in this set. I always celebrate when I see one in the field!

The greatest threats to humanity as we know it – Infographic from BBC Future.
