Anabolic steroids are synthetic hormones derived from the human male hormone testosterone. The use of steroids has been suspected in professional baseball and other sports where building muscle strength, rather than endurance, is paramount.

Exploding Asteroid Theory Strengthened by New Evidence Located in Ohio

Geological evidence found in Ohio and Indiana in recent weeks is strengthening the case to attribute what happened 12,900 years ago in North America -- when the end of the last Ice Age unexpectedly turned into a phase of extinction for animals and humans – to a cataclysmic comet or asteroid explosion over top of Canada.

Nuclear explosive devices are the most effective means of protecting Earth from possible collisions with space bodies, including comets and asteroids, a Russian nuclear physicist told RIA Novosti on Tuesday.

New test makes cheating with drugs in sports easier to detect

harminka — Thu, 19 Jun 2008 13:25:22 -0500

A new mass spectrometry test can help sports anti-drug doping officials to detect whether an athlete has used drugs that boost naturally occurring steroid levels. The test is more sensitive compared to previous alternatives, more capable of revealing specific suspicious chemical in the body, faster to perform, and could be run on standard drug-screening laboratory equipment.

Engineering researcher seeks answers to asteroid deflection

An asteroid could hit the planet Mars by the end of next month.

Asteroid is 'practice case' for potential hazards

harminka — Mon, 15 Oct 2007 11:56:23 -0500

In research that could aid decisions about future asteroids on a collision course with Earth, MIT scientists have for the first time determined the composition of a near-Earth asteroid that has a very slight possibility of someday hitting our planet.

Dawn spacecraft to examine solar history

Dinka — Fri, 28 Sep 2007 05:52:11 -0500

The US space agency NASA is going to extraordinary lengths to find out more about the history of the solar system. The Dawn spacecraft was launched this morning on a 5 billion kilometre journey to the asteroid zone between Mars and Jupiter, and if all goes well it will enter the orbit of the asteroid Vesta in 2011.

Dealing with threatening space rocks

Every now and then a space rock hits the world's media – sometimes almost literally. Threatening asteroids that zoom past the Earth, fireballs in the sky seen by hundreds of people and mysterious craters which may have been caused by impacting meteorites; all make ESA's activities in this field, including the Don Quijote study, look increasingly timely.

AKARI’s observations of asteroid Itokawa
