Gleanings of the Week Ending November 28, 2015

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.

Plastic by the Numbers in the Atlantic Ocean – Samples taken during the Atlantic Rally for Cruisers show that microplastics are very common. There were 0 samples without any plastic! On a personal level, I’m reading labels on face washes and toothpastes now and not buying any that have microbeads.

6 Common Activities that Harm Wildlife – One of the six is ‘microbeads’ so another spur to action. The other activities are also thought provoking: sunscreen, feeding bread to birds, bleached products, removing weeds, and plastic bags. Most of them I had heard about before…sunscreen only recently.

Are superbugs deadlier near where you live? – They are everywhere…some places worse than others. Often they are indicators of use (and misuse) of antibiotics.

An easy pill to swallow – Research into a mechanism to deliver mucoadhesive patches via pill through the digestive tract to the small intestine. There is potential that this could change delivery of protein based therapies (insulin, growth hormone, antibodies, and vaccines) from a injections to a pill.

A Flight of Birds – 14 unusual birds…portraits from the Photo Ark project (one of the 14 is a California Condor)

800-Year-Old Ancient Extinct Squash Uncovered during Archeological Dig on Menominee Indian Reservation – I’d like to see this one in my grocery store!

Shenandoah National Park Counting on Beetles to Slow Invasive Insect – The wooly adelgid is killing the hemlocks in Shenandoah (and in our area of Maryland too). Shenandoah is importing a beetle from Japan (where the wooly adelgid came from). Evidently the beetle has already been used successfully in other parks, including Great Smoky Mountains National Park.

1,700-Year-Old Roman Mosaic Discovered During City Sewer Construction Project – Found in Israel by workers upgrading the sewer system.  It was the floor of a large room in a villa during the Roman period.

Pictures: Great Smoky Mountains National Park  and Pictures: Rocky Mountain National Park and Explore the Power of Parks – From National Geographic…lots of great pictures, of course.

Obesity: A Complex Disorder – Graphic from The Scientist with a link at the bottom for the full article. The more we learn about obesity, the more complex it seems to become.

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.

Globe Is Set to Cross 1 Degree C Temperature Increase Threshold in 2015 – Not good. The averages for temperature and carbon dioxide concentration is the atmosphere are still climbing…and we have done nothing so far to change the trend.

Weight’s the Matter? – The Scientist has an issue on obesity and I am including the articles I found most interesting in this gleanings list. This post outlines the articles available…from causes to the link to cancer (did you know that obesity has replaced smoking as the top preventable cause of cancer death in the US?) to possible side effect of environmental chemicals to weight loss.

Obesogens – Environmental chemicals change cause metabolic changes in animals causing them to gain weight. It is harder to prove for humans…but there are a lot of obese people these days. Maybe sedentary life style and high calorie diets are not the only reason.

Microbesity – Gut bacteria play a role in obesity too.

How to Design within Novel Ecosystems – Strategies when it isn’t possible to restore an area to its natural state….how to create something that still has high ecological value.

Ancient brains turn paleontology on its head – 520 million year old arthropod brains. When the first one was discovered, it was viewed as a fluke. Now there are more and the assumptions that said that brains are never fossilized are falling away.

6 Asian Noodles – Sometimes an article encourages action. This one caused me to add soba noodles to my grocery list and I’ll be trying them this week! I like that they have more protein than most noodles.

Insect Wings Made to Look like Blooming Flowers Explores Natural Concept of Mimicry – Beautiful work by a Paris-based artist….although I have to make an effort to not think about all the insects that were sacrificed.

Scientists Grow Beautiful Designs for First Ever Microbial Art Competition – A different type of media: bacteria and fungi in petri dishes!

The Chemistry of Silly Putty – A simple ‘toy’

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.

A Visual Guide to Chemistry Glassware - A vocabulary lesson in glassware!  Probably everyone knows the difference between a test tube and a beaker…but what about a conical flask and volumetric flask?

From soda bans to bike lanes: Which 'natural experiments' really reduce obesity? - Which changes have made an impact? Studies that included longer follow-up periods after a change showed stronger results. Two examples of changes with strong impact were trans-fat bans and active transportation infrastructure improvement.

50% Driving Ban for Paris Due To Air Pollution - Weather conditions in Paris cause spikes in air pollution this time of year. We normally thin of the larger cities in India and China having the worst air pollution problems. The World Health Organization estimated that air pollution contributed to the deaths of 7 million people in 2012…so it is not an insignificant issue for the world.

Science Photographer Reveals Beauty of the Microscopic World - Manipulation of light through the microscope: transmission, differential interference contrast, optical staining, or dark field contrast.

Adapting to climate change will bring new environmental problems - Can we adapt in a sustainable way…or will our adaptation be short-sighted - and bad for the planet in the long term?

Archaeologists discover Maya 'melting pot' - Evidently mobile groups of hunter gatherers came together with settled groups for construction projects and public ceremonies --- they interacted much more than previous thought. They eventually became more uniformly sedentary.

Genome Study Predicts DNA of the Whole of Iceland - The DeCode project has collected enough full DNA sequences from Icelanders to extrapolate to the whole population (because the people are related). From this analysis, they know that 2,000 people in Iceland have the BRCA2 gene….but cannot tell them. The ethics associated with new technology is complex. In this particular case there is a “right ‘not to know’ of genetic hazards.” With more and more genome data being collected - other nations will soon have the same issue Iceland is facing now.

The Last 200 Years Of U.S. Immigration In One Chart - Click in the upper left corner to enlarge the plot. The overall trend is as interesting as where people came from. World War II had quite an impact while World War I did not.

SolarCity to build its own power grids - The market for solar technology seems to be developing very quickly. There are so many more options now than there were 5 years ago. When will the tipping point come…when more people will have solar - or some form of renewable energy where they live and work.

Compulsive Behavior Sells - Habit-forming technology….a little scary. How quickly will people train themselves to realize that it is happening?
