Professor Andrew Boulton and his team used green bottle fly larvae to treat 13 diabetic patients whose foot ulcers were contaminated with MRSA and found all but on...

Scientists rid stem cell culture of key animal cells

Tackling a pressing and controversial technical barrier in stem cell biology, scientists at the WiCell Research Institute and the University of Wisconsin-Madison have crafted a recipe that allows researchers to grow human embryonic stem cells in the absence of mouse-derived "feeder" cells, long tho...

Sex involved in plant defense

...ized plant-eaters are attracted to them. Johnson says the nuanced results make sense. "Sex shuffles up genes and allows individual plants to get rid of bad genes and keep good ones," he said.

Researchers may have found why women have an edge on salt-sensitive hypertension

...ed. Salt-sensitive hypertension means kidneys hold onto too much salt. When the kidneys realize the blood pressure is getting too high they try to get rid of salt. If they can't, in an ironic twist, blood pressure goes even higher to help literally force salt out of the kidneys. That approach eventually ...
