Gleanings of the Week Ending July 30, 2016

We finally got some rain after a dry spell and I’m enjoying the flowers on my deck this morning.

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.

Human intelligence measured in the brain – A study that used resting-state MRI analysis on 1000s of people around the world…areas of the brain which are associated with learning and development show high levels of variability (i.e. they change their neural connections with other parts of the brain more frequently, over a matter of minutes of seconds). Further studies using the new technology may rapidly improve our understanding and diagnosis of debilitating human mental disorders such as schizophrenia and depression.

Common Foot Problems (and what to do about them) – Most of my foot problems went away when I stopped wearing high heels!

Postcards provide link to Edwardian social media – A different perspective of the early 20^th century. There is a searchable archive that is available here; I enjoyed doing searches with some family names and locations. The two most common topics that people wrote about were the weather and health!

Amazing spider silk continues to surprise scientists – Phonomic crystals – that’s new vocabulary for me this week. Evidently research on spider silk has shown the potential of new materials (to synthesize) to dampen sound or provide insulation.

Hundreds of years later, teeth tell the story of people who didn't get enough sunshine – Dentin layers formed during a time when a person did not get enough Vitamin D to fully mineralize the structures that form dentin (and bone) provide a window into that aspect of nutritional health long after the person dies…longer lasting that the bones. Dentin layers are also a better indicator because they are not constantly remodeled during life as bones are.

The key to conservation is not what you think – A thoughtful piece about the lack of diversity, equity, and inclusion in the environmental community.

NASA’s Kepler confirms 100+ exoplanets during its K2 mission – Lots of validated exoplanets to pick from for further study by NASA’s upcoming missions: Transiting Exoplanet Survey Satellite and James Webb Space Telescope!

The mystery of why you can’t remember being a baby – A summary of research on the topic….and we still don’t really know the answer.

How the body disposes of red blood cells, recycles iron – It happens in the liver, not in the spleen as previously thought…and requires bone-marrow-derived immune cells as the recycling cells.

Orangutan Imitates Human Speech – 500 vowel-like sounds…more vocal fold control that we previously thought could be exhibited by a non-human ape.
