Greatest thing since sliced bread: New data offer important clues toward improving wheat yields
Breed a better crop of wheat? That's exactly what a team of researchers from Kansas State University and the U.S. Department of Agriculture hope their research will lead to. In their study, appearing in the March 2009 issue of the journal GENETICS ( http://www.genetics.org ), they analyzed the t...

Fuel cells help make noisy, hot generators a thing of the past

Laboring without the labor bed: It's a good thing

Humans may be losers if technological nature replaces the real thing
