New view of leukemia cells identifies best treatment options, Stanford researchers say
...single, uniform entity. When they take a sample to determine
how far the cancer has progressed, the entire cancer gets graded on a scale of 1 to 4, with 4 being the most severe. But Nolan and Irish found that many different populations can exist within a cancer at any point in time. Some of these populations a...

the potential influence of sleep states. The mechanism of caffeine's action on the peripheral chemoreflex was assessed by monitoring immediate changes in the respiratory pattern in response to a 30-s hyperoxic test performed during active sleep or qu...
How wounds heal Clues from flies
...mammalian wound response has challenged efforts to determine
their individual roles. Michael Galko and Mark Krasnow of Stanford University turned to the quintessential genetics organism, Drosophila melanogaster, to create a novel system for studying wound healing. After stabbing fruitfly larvae with a needle t...
UAB creates the first Internet server to search for genetic diversity
... In the case of our own species, these differences determine
whether a person has blue or brown eyes, fair or dark skin, or a higher or lower risk of getting a certain type of cancer. This is why genetic variability, as well as being a key element in evolutionary biology and in biology in general, provides ver...
