Our brains are better at hearing new and approaching sounds than detecting when a sound disappears, according to a study published today funded by the Wellcome Trust. The findings could explain why parents often fail to notice the sudden quiet from the playroom that usually accompanies the onset of mischief. Hearing plays an important role as an early warning system to rapidly direct our attention to new events. Indeed we often rely on sounds to alert us to things that are happening around...

A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences. This precisely focused therapy combines short strands of "antisense" nucleic acid-like...

People with good hearing also have a keen sense of touch; people with impaired hearing generally have an impaired sense of touch.

Touch sensitivity is hereditary and linked to genetic mechanisms that support hearing Vision and hearing are so crucial to our daily lives that any impairments usually become obvious to an affected person. Although a number of known genetic mutations can lead to hereditary defects in these senses, little is known about our sense of touch, where defects might be so subtle that they go unnoticed. In the 1 May issue of the online, open-access journal PLoS Biology, Gary Lewin's laboratory...
