Gleanings of the Week Ending October 01, 2016

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.

Images of the world’s greatest cities before they were cities – Visual history.

Internet addiction may indicate other mental health problems in college-aged students – An Internet Addiction Test was developed in 1998; this study indicates that the test may need to be updates…that there are significantly more students having trouble dealing with their day to day activities because of their internet usage. Also – are mental heal issues a cause or consequence of excessive reliance on the internet?

UK’s Oxford tops world ranking of best universities; US had 3 of top 5 – This UPI article also provides a link to the annual list (here if you want to jump there directly). There is a short blurb for each school as well.

The Good Guide to Milk: Cow: Soy, Nuts & More – I’ve switched from almond to soy milk based on this article. I’d switched to almond milk several years ago when I finally realized that almost all my stomach issues were caused by lactose intolerance.

50-country comparison of child and youth fitness levels: US near the bottom – Not good. The US is 47 out of 50. I wonder how long it has been this bad. So much has changed over the past 50 or so years. Many neighborhoods are not walkable…streets are too busy/dangerous for bicycling…parents are worried about children being outside without direct supervision.

View 3500+ Art Exhibits Online – A blurb from Free Technology for Teachers. Another source for free ebooks, specifically about exhibits at MoMA.

Greenland ice is melting 7% faster than previously thought – The hot spot that feeds Iceland’s active volcanoes is responsible. Uplift is happening a differing rate as well.

Sesame: Little Seeds, Big Benefits – Another seed to keep on hand. I use chia seeds the most but sesame seeds (and tahini) are a close second.

Ancient Skeleton discovered on Antikythera Shipwreck – From 65 BC...and now they can use DNA to learn more about a person that lived 2100 years ago.

Grading the Presidential Candidates on Science – From Scientific America. A compilation of answers on a number of science related issues from all 4 candidates.

Gleanings of the Week Ending July 9, 2016

The machines that run the internet – A short film.

A Murder of Crows: When Roosting Crows Come to Town – We don’t have large number of crows in our area – but we are seeing more than we were a few years ago when West Nile Virus killed so many of them.

Picky Eaters: Bumble Bees prefer plans with nutrient-rich pollen – The protein to lipid ratio makes a difference to bumble bees!

Ocean Acidification and Chemical Signaling – How ocean acidification impacts chemical signally of shell fish…an infographic about research on peptides that are involved in detecting predators, homing, and reproduction.

How one of history’s bloodiest wars eventually saved lives – By the end of World War I, combatant deaths has reached 10 million. Twice as many were injured. Post-traumatic stress disorder was recognized for the first time – called ‘shell shock.’ Blood transfusion, oxygen and treatment on the front lines became the norm. See some of the devices developed and used during that time period in this post or at the Wooded exhibition at London’s Science Museum.

Floating Solar: A Win-Win for Drought Stricken Lakes in the US – Will this idea become reality? It seems that in places where water is scarce that reducing evaporation and producing power at the same time would be a positive thing.

Humans artificially drive evolution of new species – Human drive extinction but also speed up evolution of new species as well. For example – a common house mosquito has evolved into a new species that thrives in subterranean environments – like subway stations; it can no longer interbreed with its above ground ancestor species.

Beyond Sightseeing: You’ll Love the Sound of America’s Best Parks – A project to record the (non-human) sounds of national parks.

Boosting potency of broccoli-related compound for age-related macular degeneration – Macular degeneration impacted the last few years of my grandmother’s life and I still notice articles about current research on prevention and/or remediation…. macular degeneration might happen to many of us as we get older.

Vanishing Act: Why Insects are declining and why it matters – Another example of the importance of biodiversity to our future…and the future of the planet.
