Archeologists have unearthed the oldest wine-making facility ever found.

Groups developing a gel to protect women from HIV/Aids say they are moving ahead to develop the product that was hailed as "groundbreaking".

Researchers who discovered stem cells and the appetite hormone leptin are named in the 2010 Thomson Reuters predictions to win Nobel prizes.

Francis Collins, who helped map the human genome, did not get around to having his own genes analysed until last summer. And he was surprised.

The quest for a cream or gel to prevent Aids infection has narrowed to using powerful HIV pills that are already on the market, scientists say.

Doctors who surprised the world of Aids research with a study showing a vaccine prevented some HIV infections released their findings on Tuesday.

Saying the new H1N1 virus is ''unstoppable'', the World Health Organisation gave drug makers a full go-ahead to manufacture vaccines

A top global health official predicted that up to a third of the world's population could eventually become infected with the new H1N1 flu.

HIV/Aids vaccine researchers should move to smaller, more focused trials and dump any vaccines that do not show strong promise.

Massachusetts Senator Edward Kennedy, the brother of assassinated president John F Kennedy and the elder statesman of American liberal politics, has a malignant brain tumour, his doctors said on Tuesday. Kennedy (76) who has been hospitalised in Boston since he had a seizure on Saturday, will likely need chemotherapy and radiation therapy to treat the glioma.

By crushing a widely used semiconductor into nanoparticles, researchers said this week they have created a compound that could lead to cleaner, more efficient refrigerators, solar power plants and other devices. The crushed material makes it possible to conduct electricity without conducting so much heat, solving a problem that has baffled engineers for 50 years.

Overeating disrupts entire networks of genes in the body, causing not only obesity, but diabetes and heart disease, in ways that may be possible to predict, researchers reported on Sunday. The researchers developed a new method of analysing DNA and used it to discover that obesity is not only complex, but complex in ways that had not been previously understood.
