Gleanings of the Week Ending February 25, 2017

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.

Busy Bees: Patterns of pollen and nectar foraging specialization by bumblebees over multiple timescales using RFID – At the top of my list this week…the paper (link is at the bottom of this post), is authored by my son-in-law and daughter!

Automatically darkening windows in a wide range of colors – Maybe insulating drapes will not be needed in the future…although I like the idea of windows that generate power rather than just changing color.

From Vector to Zoonotic: A Glossary for Infectious Diseases – Some of these words are used in news stories without definition….how strong is your knowledge of what they really mean?

How Blizzards and Extreme Cold Impact Birds – We haven’t had any extreme cold in our area this winter….but it may be happening somewhere. This article talks about the studies about how birds cope with the cold; some succumb to the cold itself and some starve because their food source becomes unavailable.

Why Killer Viruses are on the Rise – An outcome of our increasing impact on environments that previously were wildlife habitats.

Winning images of the Underwater Photography of the Year Contest – Eye candy…but educational too.

NASA’s Osiris REx takes its first image of Jupiter – We saw Osiris REx launched last September so I always take a look at any new news about it.

Torpid Turtles, Tortoises, and Terrapins – Examples from turtles in the US…several are common enough in Maryland that I’ve seen them.

The oldest grave of the Netherlands, “Trijntje” – A facial reconstruction of a woman buried 7500 years ago.

The Feather Atlas – A feather reference. I hope I remember this exists the next time I find an interesting feather!

Peacock Feathers

I’ve tried to photography peacock feathers by getting close to them…but decided to use the zoom on the camera instead yesterday. I put the feathers in front of a window to use natural lighting. It was more satisfied with the result than my previous attempts although it is hard to capture the iridescent quality of the color.

These feathers are over 30 years old. My grandmother picked up feathers that her peacocks shed one year in the early 1980s and then gave them to her granddaughters at Christmas time. I am so glad I still have them!

Looking closely at the images – it is possible to see the dust that the feathers have accumulated. They are getting fragile and I try to not touch them these days…let along try to dust them.
