Physicians testified for tobacco companies against plaintiffs with head, neck cancers, Despite scientific evidence to the contrary, a small group of otolaryngologists have repeatedly testified, on behalf of the tobacco industry, that heavy smoking did not cause the cancer in cases of dying patients suing for damages.
Cure for flesh-eating skin disease one step closer Scientists have made an important breakthrough in the fight against the flesh-eating tropical skin disease Buruli ulcer, by their discovery that the bacteria causes a blood clot in patients' skin, similar to those that cause deep vein thrombosis (DVT). The new findings mean that, like DVT, the clots may respond to anticoagulant medicines, heal more quickly and with fewer side effects than with antibiotics alone
Brain training may help avoid civilian casualties A new study finds that accidental civilian shooting casualties arise from problems with attention -- an "itchy brain," the authors say -- rather than an "itchy trigger finger." The findings imply that the tendency to squeeze the trigger in error can not only be predicted with cognitive tests but can also be overcome with response-inhibition training.
New findings hint toward reversing hearing loss Studying mice, scientists have identified two signaling molecules that are required for the proper development of a part of the inner ear called the cochlea. Without both signals, the embryo does not produce enough of the cells that eventually make up the adult cochlea, resulting in a shortened cochlear duct and impaired hearingNew finding on the formation of fat tissue in humans Bone marrow contains stem cells that normally give rise to new red and white blood cells. A team of researchers from Sweden and France has now shown that bone marrow cells can also form fat.
