Alzheimer's patients who are taking antipsychotic drugsThe study, funded by the Alzheimer's Research Trust, was led by Prof Clive Ballard's King's College London team and is published in Lancet Neurology on 9 January.
The study involved 165 Alzheimer's patients in care homes who were being prescribed antipsychotics. 83 continued therapy and the remaining 82 had it withdrawn and were instead given oral placebos.

What drives one of nature's powerful, nanoscale motorsPeering at structures only atoms across, scientists have identified the clockwork that drives a powerful virus nanomotor.
Because of the motor's strength--to scale, twice that of an automobile--the new findings could inspire engineers designing sophisticated nanomachines. In addition, because many virus types may possess a similar motor, including the virus that causes herpes, the results may also assist pharmaceutical companies developing........Go to the Infectious disease blog (Added on 1/8/2009 7:59:59 PM)
