Comprehensive look at rare leukemia finds relatively few genetic changes launch disease

The most comprehensive analysis yet of the genome of childhood acute myeloid leukemia (AML) found only a few mistakes in the genetic blueprint, suggesting the cancer arises from just a handful of missteps, according to new findings from St. Jude Children's Research Hospital. The research appears i...

Scientists should look at their own carbon footprint

New studies indicate the three drugs used to treat male impotence also appear to work in females, albeit a little differently, and should give the scientific community pause to take a second look at their potential in the 40 percent of women who report sexual dysfunction, researchers...

Brown-led team offers first look at how bats land

PROVIDENCE, R.I. [Brown University] People have always been fascinated by bats, but the scope of that interest generally is limited to how bats fly and their bizarre habit of sleeping upside down. Until now, no one had studied how bats arrive at their daytime perches. A Brown University-led re...

Symposium to look at genetic basis of exercise

BETHESDA, Md. (Mar. 18, 2009) 'Adaptation to exercise' is a familiar phenomenon, even if the phrase is not: A sedentary person takes up jogging and can barely make it around the block. After jogging regularly for a few weeks, the person can jog a mile, then two, then three. With regular exercise, ...

University of Minnesota researchers take new look at cellular suicide

Like a bodyguard turned traitor, a protein whose regular job is to help repair severed DNA molecules will, in some cases, join forces with another protein to do the opposite and chop the DNA to bits, according to new research at the University of Minnesota. The chopping up of a cell's DNA occurs in...
