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).

Gleanings of the Week Ending February 27, 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.

Keep off the grass – Some areas are better as being grasslands than forests…and our planet needs those grasslands!

Dodos might have been quite intelligent – It turns out that Dodos has brains that were the same size as pigeons relative to their body size…and they had relatively larger olfactory bulbs so they probably had a better since of smell.

This bus-size whale is even more unusual than we thought – Omura’s whale devours tiny shrimp-like creatures plus large mouthfuls of ‘dirty water’ (that includes fish eggs and plankton almost invisible to the human eye. They sing a low repetitive melody for an hour or more. What will happen to these whales when the oil and gas exploration gets underway in the area where they live. Is the technology good enough to keep the petrochemicals from leaking into the water?

Reflection – Another photographic project idea!

Collect psychology classes lack curriculum about disabilities – A study pointing out that classes intended to focus on interactions with people of all types have a hole when it comes to people with disabilities – particularly physical disabilities.

Total Solar Eclipse – August 2017 – Planning ahead. It doesn’t happen very often and the path for this one is a diagonal across the continental US.

FDA to test for glyphosate in food – Finally! When Roundup first came out we used it to kill weeds growing in the cracks of our sidewalk. It was never sprayed close to anything we were going to eat. But now, because food crops are engineered to not be killed by it, it is sprayed on food crops like soybeans and corn…so it goes into our food system. It’s a little scary that the study was not done before now.

Antarctica could be headed for a major meltdown – The last time Earth’s atmosphere had about the same amount of carbon dioxide as it does now was about 16 million years ago…the temperatures were 10 degrees warmer and the ocean levels were 50 feet higher. And we have some observations that indicate that the ice shelves of Antarctica are melting rapidly: 7 of 12 ice shelves on the Antarctic Peninsula had collapsed over past few decades.

Elementary School Lessons about Fossils and Rocks – I’m always on the lookout for one page references and this resource includes a good one for rocks (here).

Share your Field Notes: Nature’s Notebook – A citizen science project about phenology (the timing of natural events like blooming flowers and migrating animals…a great way to spend time outdoors and contribute valuable observations to science.
