Ebola, your days as one of the world's scariest diseases may be numbered.

A team of U.S. government researchers has shown that deadly Ebola hemorrhagic fever can be vanquished in monkeys by an experimental drug given up to five days after infection — even when symptoms have already developed.

An antibody cocktail aimed at Ebola's outer surface rescued three of seven macaques infected with lethal doses of the hemorrhagic virus in the U.S. Army's high-security labs at Fort Detrick, Md.

'Why This Compulsion To Run Long Distances?' A Runner's Beautiful Confession

From Racing the Antelope

Biologist Bernd Heinrich was in Zimbabwe, in the field, eyes down, looking for beetles, when for no particular reason he looked up and saw ... well, at first he wasn't sure what it was, so he stepped closer, leaned in, and there, painted on the underside of large protruding rock, were five human figures "running in one direction, from left to right across the rock face." They weren't very detailed, just "small, sticklike human figures in clear running stride" painted by a Bushman, two, maybe three thousand years ago.

The notion that sport shoes and inserts should keep the human arch stiffly supported is a decades-old assumption that could use some rethinking, according to a British gait analyst who has closely studied more than 25,000 footsteps of healthy people.

How risky are psychedelic drugs to mental health? Not nearly as much as you might have imagined.

People who had taken LSD, psilocybin (the brain-bending chemical in magic mushrooms) or mescaline at any time in their lives were no more likely than those who hadn't to wind up in mental health treatment or to have symptoms of mental illness, according to an analysis by some Norwegian researchers.

And there was some evidence that people who had taken the drugs at some point were less likely to have had recent mental health treatment.

Facebook's mission "to make the world more open and connected" is a familiar refrain among company leaders. But the latest research shows connecting 1.1 billion users around the world may come at a psychological cost.

A new University of Michigan study on college-aged adults finds that the more they used Facebook, the worse they felt. The study, published in the journal PLOS One, found Facebook use led to declines in moment-to-moment happiness and overall life satisfaction.

Global sea level has been rising as a result of global warming, but in 2010 and 2011, sea level actually fell by about a quarter of an inch.

Scientists now say they know why: It has to do with extreme weather in Australia.

The sea level drop coincided with some of the worst flooding in that continent's history. Dozens of people died and torrents washed away houses and cars, forcing thousands from their homes.

Chia-Jung Tsay was something of a piano prodigy. By age 12, she was performing Mendelssohn in concert. At 16, she made her debut at Carnegie Hall. Soon, she was on her way to some of the best music schools in the country — Juilliard and the Peabody Conservatory. And she was throwing her hat in the ring for different competitions.

Lyme Disease Far More Common Than Previously Known

Black-legged ticks like this can transmit the bacterium that causes Lyme disease.

Originally published on Mon August 19, 2013 6:58 pm

The Centers for Disease Control and Prevention says 300,000 Americans are getting Lyme disease every year, and the toll is growing.

"It confirms what we've thought for a long time: This is a large problem," Dr. Paul Mead tells Shots. "The bottom line is that by defining how big the problem is we make it easier for everyone to figure out what kind of resources we have to use to address it."

Incredibly Shrinking Avocados: Why This Year's Fruit Are So Tiny

We found lots of avocados being sold six or 10 to a $1 bag in the San Francisco area. Some weighed less than 3 ounces.

What's thick-skinned and leathery, about the size of an egg, essential for guacamole and sold eight for a dollar?

No, not limes. Hass avocados. This year, anyway. These pear-sized fruits usually weigh half a pound or more. In the summer of 2013, though, hundreds of thousands of trees in Southern California are sagging with the tiniest Hass avocados in local memory — some just the size of a golf ball.

How One Plus One Became Everything: A Puzzle of Life

Courtesy of Paolo Ceric

It's one of life's great mysteries ...

Four billion years ago, or thereabouts, organic chemicals in the sea somehow spun themselves into little homes, with insides and outsides. We call them cells.

They did this in different ways, but always keeping their insides in, protected from the outside world ...

... surrounded by walls or skins of different types ...

... but letting in essentials, nutrients. Some even learned to eat sunshine, capturing energy ...

... which gave them a pulse of their own ...

... so they could move ...
