Stuart Blackman completed a PhD in evolutionary biology at the University of Edinburgh in 1995 and immediately began working as freelance writer. He has since written for Nature Publishing Group, New Scientist, BBC radio, and The Scientist. On page 17, Blackman writes about a marine bacterium that produces dimethyl sulfide (DMS)- a major source of sulfur in the earth's atmosphere and a long-missing link in the climate system. Some have dubbed the gene for DMS "the weather gene.

"The EU must first support home-grown researchers until they can compete on a level playing field with US scientists." Putting companies on notice As a public relations counselor, I agree completely with your requirement that companies seeking coverage should provide news, not "unquestioning boosterism."1 They should understand that real news about their products serves their interests, not just the journalist. At the same time,

When the English racing driver Lewis Hamilton finished third at Formula One's Australian Grand Prix in March, it made him the first rookie driver to reach the podium since Canada's Jacques Villeneuve managed it 11 years before.

A few, notably racing legend Jackie Stewart, mentioned the extensive tra

On May 27, 1961, Heinrich Matthaei, a postdoc working with NIH scientist Marshal Nirenberg, placed synthetic polyuracil RNA into 20 test tubes to see what it would produce. Each tube contained cytoplasmic extract from Escherichia coli and a specific radiolabeled amino acid. Ribosomes from the tube containing labeled phenylalanine came back 'hot,' and the world was a step closer to understanding the genetic code.CLICK HERE for a larger version of this image
