Daily pill to 'cure Alzheimer's'
(Jul 24, 2006)
Scientists have developed a once-a-day pill that they hope could potentially cure Alzheimer's disease. Tests in mice have shown the drug, PBT2, prevents build up of the amyloid protein linked to the disease. Protein levels dropped by 60% within 24 hours of a single dose, and memory performance improved within five days.

Clone 'would feel individuality'
(Jul 20, 2006)
A cloned human would probably consider themselves to be an individual, a study suggests. Scientists drew their conclusions after interviewing identical twins about their experiences of sharing exactly the same genes with somebody else. The team said the twins believed their genes played a limited role in shaping their identity.

Meerkat pups go to eating school
(Jul 13, 2006)
Meerkat pups do not learn how to eat dangerous animals such as scorpions on their own but are taught by adults, scientists have discovered. Researchers found that adults bring dead animals to the youngest pups. As pups get older, helpers disable live prey for them; finally they coax the youngsters to hunt for themselves.

(Jul 4, 2006)
UK scientists have developed technology that enables artificial limbs to be directly attached to a human skeleton. The breakthrough, developed by researchers at University College London, allows the prosthesis to breach the skin without risk of infection. The team says early clinical trials have been "very promising".
