Life as a male anole lizard defending its territory against other male lizards is a lot of work. As is the life of the single-minded scientist who chooses to study them.

After trial-by-fire training during the feverish early days of HIV research, Amanda Fisher has kept up the pace in the hot fields of epigenetics and nuclear reprogramming.

Neuroprosthetics Today For more than 20 years, researchers at the Cleveland Functional Electrical stimulation (FES) Center have been training patients with paralysis to control their own neurological signals - not from electrodes in their brains (the focus of our feature Of Cells and Wires), but from those implanted in muscles. Watch the video below to learn how.

Darwinian Time Does adaptation to an environment act as a speed bump for evolutionary change? By Andrea Gawrylewski Illustrations by JT Morrow Photos by Stephen Kennedy n a windowless room, three researchers hunker over a waist-high lab table. Dressed in white coats and latex gloves, the investigators, all members of the Washington University School of Medicine in St. Louis, get down to the business at hand: skinning frozen mice.

Priority Setting at the NIH © Dustin Fenstermacher / Wonderful Machine Nearly 10 years after stepping down as director, Harold Varmus reflects on his life at the agency, and some of the delicate negotiations that often precede funding decisions. By Harold Varmus Editor 's note : The following is an excerpt from Harold Varmus's upcoming memoir, The Art and Politics of Science, (Norton Books, Feb. 2009). In his book, Varmus recounts his days at

As a grad student at the University of Edinburgh, Elie Dolgin wrote and recorded science radio shows and podcasts in between experiments with C. elegans. Within only weeks of defending his thesis, Dolgin became an editorial intern at The Scientist. "I liked The Scientist because, even though I was no longer a practicing scientist, for the first time I felt I was part of a sc

US healthcare needs radical revision, but we can't wipe out innovation in the process.

Citation debate hits Cell The general issue highlighted in the post "Critics rip Cell paper"1 and many of the comments that followed is one of "selective citation," in which papers fail to include all relevant prior art. I believe that this example reached the current level of scrutiny because the complainant, Peter Lawrence, is a well-known scientist and he was willing to raise a

Few people possess a perfect sense of direction. Some need a GPS just to find their wits. Then there's Patient 1. Patient 1, as Giuseppe Iaria and his colleagues refer to her in an online article in Neuropsychologia(doi:10.1016/j.neuropsychologia.2008.08.021), doesn't even try to drive because she gets turned around in her own neighborhood. Family and friends accompany her almost every

These traditional customs seemed to work. But Foster wasn't entirely convinced. Star
