Gleanings of the Week Ending December 3, 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.

Mysterious Winds Cause Rapid Melting of Antarctic Ice – Fohn winds….a warm wind that may be responsible for calving ice shelves. And some of their most impressive heat waves come in the dead of winter, eroding glaciers at a time of year that no one thought possible.

Electron Micrographs Get a Dash of Color – And they used red and green…so the images looks very Christmassy!

Ancient Royal Boat Tomb Uncovered in Egypt – Found while investigating the tomb complex of 12^th dynasty King Senwosret III, located in southern Egypt. The walls of the tomb covered with sketches of boats.

How the Enormous Field of Physics All Fits Together – A short video (less than 10 minutes) that provides a big picture Physics.

NASA’s Bold Plan to Hunt for Fossils on Mars – Fossils of single celled algae and bateria…maybe taking a look at the cauliflower-shaped silica formations inside Mars’s Gusev Crater that look like objects sculpted by bacteria living inside hot springs on earth.

What it’s like to sail a giant ship on Earth’s busiest seas – Part of the BBC’s Future Now series.

Cuba’s Underwater Jewels are in Tourism’s Path – Gardens of the Queen National Park: keys, mangrove islets, and reefs about 50 miles off Cuba. Cuba limits the number of divers and fishermen allowed to visit but could face pressure to increase access.

Birds have skills previously described as ‘uniquely human’ – Caledonian crows use tools, scrub jays remember past events and act accordingly, pigeons can be trained to recognize patterns of letters (words). But they may be processing stimuli differently than humans. Maybe no two species are the same but the brain is often adaptable enough to find a means to meet the needs of the animal.

The most Visual Science Textbook You’ve Ever Seen – History of Evolution….and images of example along the way.

The Chemistry of Turmeric – Fluorescence, Indicator, and Health Effects – The post includes an infographic but the short video is worth watching (rather gathering materials to do the experiments yourself).

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.

What would happen if the world suddenly went vegetarian? – Of course, it’s not likely that the world will suddenly become vegetarian but this article talks about the ‘what if’ and encourages thinking about taking steps to reduce portion side of meats we eat and/or substitute a plant protein for meat in some of our meals.

Hubble spots possible water plumes erupting on Jupiter’s moon Europa – Another discovery --- and something to look at with the James Webb Space Telescope (to launch in 2018). If confirmed, Europa will be the 2^nd moon in the solar system known to have water vapor plumes (Enceladus, a moon of Saturn, has jets of water vapor and dust that were discovered by NASA’s Cassini orbiter in 2005).

Our IQs have never been higher – but it hasn’t made us smart – It turns out that IQ is malleable over a lifetime. People that are physically and intellectually active…and are overall healthy…have higher IQs, in general, than people who are not. It does not mean that we are wiser…just that IQ is higher.

Acidity in atmosphere minimized to preindustrial levels – Result from studies of the Greenland Ice Sheet. The human-made acid pollution peaked in the 1960s and 70s and we are not back to the levels in the 1930s.

Tips for creating an introvert-friendly workplace – An article from CIO magazine. Read it as a case study on some things that need to be considered: communication, comfort zones, company culture, and the workplace structure.

New evidence shifts the timeline back for human arrival in the Americas – An archeological site in Argentina…humans were there 13,068-14,064 years ago….that’s earlier than Clovis people in North America (around 13,000 years ago).

The astronomical cost of going to Mars – and staying there – Sustaining people on Mars quickly exceeds getting them there. There is a lot of talk of getting to Mars (i.e. the transportation) and not as much about what would happen once people got there.

How the Electricity Grid Works – An Infographic. In the US there are three grids: The Eastern Grid, the Western Grid, and the Texas Grid – with the Eastern being the largest.

Washing Clothes Releases Thousands of Microplastic Particles into the Environment – Three types of textiles were examined: cotton/polyester, polyester, and acrylic. They all release a lot of very small plastic particles (acrylic releasing the most…cotton/polyester the least). Reduction of emissions will take changes in textile design and/or improved filtration of effluent for these very small particles.

Pumpkin Pie Mousse – I like pumpkin custard – one of the favorite fall desserts around my house – but this is something I am going to try. No cooking!

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.

Hawai’I at the Energy Crossroads – A case study about the issues with how we produce electricity – now and into the future.

“Top tips for men juggling a successful career and fatherhood” hilariously nails how sexist the advice given to working women is – For anyone that doubts that gender bias is still quiet prevalent in the workplace.

Ancient tsunami evidence on Mars reveals life potential – Evidence of cold, salty oceans on Mars (the image of Mars was produced using Google Earth!)

Restoring an Ancient Nursery for Atlantic Sturgeon – These fish can reach 14 feet in length and weigh 800s pounds – a species that has been around since the dinosaurs. In the 1890s, caviar from Delaware River sturgeon was a thriving enterprise. Within a decade, the population of sturgeon fell to 1% of its historic numbers. Even with a moratorium on sturgeon fishing in the 1990s, the fish were not recovering due to ship strikes, channel dredging, and poor water quality. Now – with focus on dissolved oxygen, salinity, and flow conditions….and understanding the extent of spawning and nursery habitat in the freshwater portion of the river…slow recovery is beginning.

Antibiotics that kill gut bacteria also stop growth of new brain cells – Another reason antibiotics should not be overprescribed….and that we look for ways to resolve an infection that does not kill gut bacteria.

Wildlife is where you find it – A reminder that the natural world often survives even in a very man-made environment…and to be observant enough to notice it.

Bright light alters metabolism – Blue-enriched light in the evening seems to be problematic….will electronic devices of the future modify the type of light they emit based on time of day to help us stay healthy?

State of North America’s Birds Report Released to Commemorate Centennial of the First Migratory Bird Treaty – Birds connect our continent and some progress has been made. There is still a lot to be done. Individual actions like choosing sustainably created products, preventing bird collisions with windows of our houses and office buildings, and participating in bird related Citizen Science project (like eBird) make a difference.

10 Overlooked Wildlife Experiences in our National Parks – Sometimes small creatures that make their homes in National Parks are just as memorable as the scenery.

Toothpaste Tips and Myths – Toothpaste comes in lots of different formulations. Educate yourself about the good – and not so good – aspects of some of the benefit claims.

Cancer’s Vanguard (exosomes) and Immune Influence and Under Pressure – From The Scientist, graphics explains some recent research findings about cancer.

Texas and California have too much Renewable Energy – There have already been instances where spot prices for power have turned negative. Large-scale storage is needed for renewable energy…and does not exist.

Fertilizer’s Legacy: Taking a Toll on Land and Water – Massive amounts of legacy phosphorous has accumulated and will continue to impact aquatic ecosystems for a very long time. The study used data for the past 70 years for 3 rivers.

The Impact of Climate Change on Public Health – Four Infographics…. there is no good news.

Buzz Aldrin’s Plan for a Permanent Presence on Mars – Part biography…part of what ‘going to Mars’ should mean.

Breakthrough Toothpaste Ingredient Hardens your Teeth While You Sleep – Not only new technology to ‘significantly reduce tooth decay’…but new ways of marketing to both professionals and consumers. I thought at first that it was all about new ways of getting the positive action of fluoride in a more effective way but toward the end of the article it says they are working on a fluoride free version.

Behind-the-Scenes…Smithsonian’s Natural History Museum – Warehouses of collections.

8 Great Food Documentaries – Short descriptions and links to trailers for some food related documentaries.

Photographer Michael Nichols on Yellowstone – A place I’d like to visit again…once is not enough.

Effects of BPA Substitutes – Not good at all. Why wasn’t research done on the replacements for BPA before they became replacements?
