Researchers at Washington University School of Medicine in St. Louis have found that multidrug-resistant bacteria and bacterial spores can be killed by ultrashort-pulse lasers. The findings could lead to new ways to sterilize wounds and blood products without damaging human cells.

Speech sounds elicit comparable neural responses and stimulate the same region in the brain of humans, macaques and guinea pigs, researchers report. The finding could help pave the way for better understanding and diagnosis of auditory processing deficits.

'Plague sceptics' are wrong to underestimate the devastating impact that bubonic plague had in the 6th to 8th centuries CE, argues a new study based on ancient texts and recent genetic discoveries. The same study suggests that bubonic plague may have reached England before its first recorded case in the Mediterranean via a currently unknown route, possibly involving the Baltic and Scandinavia.

Scientists have used glowing chemicals and other techniques to create a 3D map of the blood vessels and self-renewing 'stem' cells that line and penetrate a mouse skull. The map provides precise locations of blood vessels and stem cells that scientists could eventually use to repair wounds and generate new bone and tissue in the skull.
