There is renewed hope for treatment of a rare genetic condition that causes rapidly accelerated aging and leads to an average life expectancy of 13 years.

A Cornell researcher has found that people who had been exposed to prenatal toxins and develop later-life diseases have in common an imbalanced immune system and hyperinflammatory responses.

Blog: Organic plastic? Fantastic!

A miniaturised DNA copier that is portable, costs $10, and runs on AA batteries, could prove vital in diagnosing AIDS and TB in developing countries

A green tea extract may represent a new and natural compound for preventing and treating HIV-associated dementia, a study using a new mouse model for the devastating disease suggests.

Elderly men and women who consumed higher levels of calcium and vitamin D are significantly more likely to have greater volumes of brain lesions, regions of damage that can increase risk of cognitive impairment, dementia, depression and stroke.

Daily use of ginseng or ginkgo biloba supplements at the recommended doses, or the combination of both supplements, are unlikely to alter the pharmacokinetics -- by which drugs are absorbed, distributed, metabolized, and eliminated by the body -- of the majority of prescription or over-the-counter drugs, according to medical scientists.

The humble coral may possess as many genes -- and possibly even more -- than humans do. And remarkably, although it is very distant from humans in evolutionary terms, it has many of the immune system genes that protect people against disease. In fact, it is possible some of these were pioneered by corals.

Scientists are developing a new type of electrochemical sensor that uses a unique surface chemistry to reliably and accurately detects thousands of differing biomolecules on a single platform.

Migrating Bewick's Swans find fuel for their long flight in the leftovers in Dutch sugarbeet fields. The swans prefer to avoid humans and be near their roosts, but exactly which fields help the swans in their flight? The authors developed a calculation of energy intake to predict accurately which fields help the swans the most. This might help manage declining populations of migrating birds.

Doctors hope the treatment will allow patients with inherited childhood blindness to see again, following successful trials in dogs with the condition
