(PhysOrg.com) -- High-gain nuclear fusion could be achieved in a preheated cylindrical container immersed in strong magnetic fields, according to a series of computer simulations performed at Sandia National Laboratories.

(PhysOrg.com) -- Chemical additives that help agricultural pesticides adhere to their targets during spraying can lead to formation of smaller "satellite" droplets that cause those pesticides to drift into unwanted areas, Purdue University researchers have found.

By Gerard Wynn LONDON (Reuters) - Threats of retaliation by China and India against a European Union plan to charge airlines for their carbon emissions is misplaced, given their weak legal case and a drift towards more such unilateral climate action.

In late November 2011 I went to Johannesburg, South Africa, to meet the newest member of the human family, a nearly two million–year-old creature dubbed Australopithecus sediba. First announced in 2010, its fossilized bones have caused quite a commotion in paleoanthropological circles--and with good reason

In late November 2011 I went to Johannesburg, South Africa, to meet the newest member of the human family, a nearly two million–year-old creature dubbed Australopithecus sediba. First announced in 2010, its fossilized bones have caused quite a commotion in paleoanthropological circles--and with good reason. They are some of the most complete early hominins (the group that includes modern humans and their extinct relatives) ever found, and they exhibit a combination of apelike and humanlike traits that no one would have predicted.

Humans have a seemingly primal need to understand how we came to be the way we are today. Pieces of our ancient forebears generally are hard to come by, however.
