Gleanings of the Week Ending February 06, 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.

Tranquil Oil Paintings Reflect Peacefully Ripping Water Scenes – Gives me an idea for a photo project. And this one does too: Seeing the Trees through the Forest: Vestiges of Ancient Woods

7 Easy and Delectable Vegan Quick Breads – Goodies in winter!

Joyful Portraits of Centenarians that are Happy at One Hundred – Hurray! To be happy and 100!

This Is What 17 Different Foods Look like Growing in Their Natural Habitats – All these images are ‘beautiful food’!  The majority of these do no grow in Maryland (except in conservatories)…and I don’t think I’ve ever seen a cashew tree even in a conservatory.

America’s Broadband Improves, Cementing a “Persistent Digital Divide” – Rural areas are still problematic….maybe stratospheric drones and balloons will be deployed.

Why the calorie is broken – It turns out that the concept of ‘a calorie’ is not a clear cut as we expect….that there are lots of ways the amount of energy we get from food can be changed. In general – the processes or cooked a food is, the more energy we get from it!

The Scientific Outreach Gap – This was a study done in the UK but the same is true in the US and it isn’t that the public is not interested. My daughter has volunteers for outreach events for astronomy and astrophysics for the past few years and the events have been well attended – almost overwhelmingly so.

Beyond Half Dome: Five Yosemite Sites – Adding to the places I’d like to go (eventually)

The Mycobiome – There has been a lot of research on the human microbiome but most of it, so far, has been about surveys and studies of bacterial species. There are fungi that are there too…and research about them has just started to appear in papers in the past 5 years.

Evidence-based health care: The care you want, but might not be getting – Yes! This is what I want but it seems very hard to get. The study was specifically about hospital settings but it matches my experience everywhere in the US health system. The survey revealed that things like ‘quality’ and ‘safety’ was at the top of the priority list…but how is that achieved without being ‘evidence based.’  I think what is being measured is not skewed toward the patient but to what is easiest to measure (and that could actually be detrimental to the patient).

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.

Breakthrough discovery reveals how thirsty trees pull water to their canopies – It is cohesion and gravity rather than atmospheric pressure that is the driving principle. I always thought it was due to ‘capillary action’ but that term is not mentioned in the article at all.

Giant Clams Light Up Like Plasma Screens, Only Better – Potential for organic displays…..using the giant clam mechanism for power and color.

Photography in The Parks: Accessible Zion Through the Seasons – Nice to know that Zion has something for everybody. I missed it a few years ago when the government was shut down while I was in the area….want to try again.

How do birds stay warm on a cold winter’s night? – Huddling together seems to be popular. The article suggests providing nesting boxes to help the birds find a good place just after sunset. And another post about birds - Snow birds: 10 birds to look for in winter. The feeders at Sapsucker Woods (Ithaca, NY) have a camera on them; the video feed is here. The birds in this post are not what is visiting my feeder and bird bath right now; I’m seeing cardinals, juncos, blue jays, and doves almost every day.

Scientific Illustrator Hand-Paints Giant Mural Featuring 243 Modern Bird Families – Next time I am in Ithaca NY (Cornell University) – I’ll want to see the mural.

Infographic Offers a Valuable Guide to Feeling Happier in Your Life – Lots of variables…and this is all a matter of statistics. There are happy people that don’t meet all these….and the genetics part is something we can’t change anyway! Another perspective on the same topic from BBC Futures: A 7-day guide to the pursuit of happiness.

Arthropods Abundant in American Homes – The average US household contains 62 distinct families of arthropod species. They range from cockroaches and fleas to carpet beetles and book lice…ants. They are our (mostly) quiet and benign roommates.

Why do we get ‘eye floaters’? – Many people notice them…but they impact vision in very few cases. They are causes when small debris gets into the vitreous humor – the jelly like mass between the retina and the lens in our eyes….that is not replenished or replaced.

The Chemistry of Bread Making – A graphic from Compound Interest.
