Ancient Landscape Is Found Under 2 Miles Of Ice In Greenland

Originally published on Mon April 21, 2014 1:36 pm

A new study suggests the Greenland Ice Sheet did not fully melt during previous periods of global warming — and that it preserved a tundra beneath it.
Joshua Brown University of Vermont

In a surprising discovery, scientists have found evidence of a tundra landscape in Greenland that's millions of years old. The revelation goes against widely held ideas about how some glaciers work, and it suggests that at least parts of Greenland's ice sheet had survived periods of global warming intact.

So This Is How They Do It! Zebras Getting Stripes

How did it happen? How'd the zebra get its stripes?

In Rudyard Kipling's version, a gray, horsey-looking beast went into "a great forest 'sclusively full of trees and bushes and stripy, speckly, patchy-batchy shadows," stayed there awhile, and after a "long time"... got stripy.

OK. Not bad.

One Scientist's Quest To Vanquish Epileptic Seizures

Originally published on Fri April 18, 2014 7:13 pm

The dream of epilepsy research, says neurobiologist Ivan Soltesz, is to stop seizures by manipulating only some brain cells, not all.
Steve Zylius UC Irvine Communications

In the early 1990s, a young brain researcher named Ivan Soltesz heard a story that would shape his career.

His adviser told him about a school for children whose epileptic seizures were so severe and frequent that they had to wear helmets to prevent head injuries. The only exception to the helmet rule was for students who received an award.

"The big deal for them is that they can take the helmet off while they're walking across the stage," Soltesz says. "And that thing struck me as just wrong."

Pipeline Put Off, As Keystone Review Is Indefinitely Extended

Originally published on Fri April 18, 2014 7:13 pm

The Keystone XL pipeline remains a major point of contention within the Democratic Party, as green voters pull President Obama one direction and pro-energy senators and labor unions pull the other. It looks as though the "comment period" for the project will be extended, delaying a decision past the November elections.

Japan Says It Will Temporarily Scale Back Whale Hunt

Originally published on Fri April 18, 2014 3:12 pm

Agriculture, Forestry and Fisheries Minister Yoshimasa Hayashi speaks in Tokyo on Friday. He says Japan will cut back on the number of whales it kills this year, but resume previous levels in 2015.

Japan says it will kill fewer whales when its seasonal Pacific hunt begins next week and will only observe whales in the Antarctic, after a U.N. court ordered it to stop taking the marine mammals from the Southern Ocean.

Religion is a cross-cultural universal, even though not every human being professes faith in God or some other supernatural being. Those of us who are atheist or agnostic make up 6 percent of the American population. A further 14 percent say they are not affiliated with any particular religion.

'Completely Unique': Cave-Dwelling Female Insects Have Penises

Four new insect species found in Brazil have rather strange sex lives — to say the least. Their sex organs are reversed: Females have penises and males have vaginas, scientists reported Thursday in the journal Current Biology.

Even Chimps Know That A Firm Bed Makes For Quality Sleep

Originally published on Thu April 17, 2014 7:14 pm

A chimpanzee hangs from a tree trunk in Kibale National Park in Uganda. A new study indicates that chimps prefer a specific tree for sleeping.

In the wilds of Africa, chimpanzees consistently choose to make their sleeping nests in a particular tree that offers the "just right" kind of comfort that Goldilocks famously preferred.

That's according to a new study in the journal PLOS ONE that could also bolster a theory that solid shut-eye may have been a key to human evolution.

Scientists who have been hunting for another Earth beyond our solar system have come across a planet that's remarkably similar to our world.

It's almost the same size as Earth, and it orbits in its star's "Goldilocks zone" — where temperatures are not too hot, not too cold, and maybe just right for life.

But a lot about this planet is going to remain a mystery, because it's 500 light-years away.

Got A Hobby? Might Be A Smart Professional Move

Maybe you paint, keep a journal or knit. Or maybe you play bass in a punk rock band.

Whatever hobby you have, keep at it. A little study published this week suggests that having a creative outlet outside the office might help people perform better at work.

Psychologists from San Francisco State University found that the more people engaged in their hobbies, the more likely they were to come up with creative solutions to problems on the job. And no matter what the hobby was, these people were also more likely to go out of their way to help co-workers.
