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.

Making “Kate Tectonics” – A short video about the history of geology.

Melting Glaciers in Canada Now Major Contributor to Sea Level Rise  and Climate-driven permafrost thaw – It’s been so warm this winter in our area….and elsewhere as well.

Elite ‘Dynasty’ at Chaco Canyon Got Its Power from One Woman, DNA Shows – DNA analysis is having an impact on our understanding of prehistory. This is an example from Chaco Canyon.

How Tibetans survive life on the ‘roof of the world’ – The Tibetans manage survival in thinner are differently than the people of the Andean Altiplano.

Could you survive on just one food? – I wouldn’t want to…how boring. But is it interesting to think about the pluses and minuses of single foods. Potatoes turn out to be a viable choice – hence the Irish population boom that busted when the potato blight came along.

Waxwings really have wax wings – We don’t have enough berry producing plants in our neighborhood to attract these birds….wish we did.

Delivering on spider silk’s promise – I’ve been hearing about spider silk coming to the market (shoes, jackets) but it hasn’t happened yet and it may not except for specialty products where cost is not a key driver.

What you don’t know about the Vikings – An article with pictures from reenactments and artifacts – from National Geographic.

Top 25 Wild Bird Photographs of the Week #77 – It’s been two years since the #76 was published…I hope they come out with more frequency. My favorite of this group is the Northern Pintail. I like the light on the wings…and the water droplets splattering from the feet.

What happens when a massive redwood tree falls – 10-12 coast redwoods have fallen at Muir Woods National Monument during past two months…lots of work for the trail crew…but also new forest homes in the now horizontal tree trunks.
