The Mediterranean diet is associated with a variety of health benefits, including a lower incidence of dementia. Now, researchers have identified a specific ingredient that protects against cognitive decline: extra-virgin olive oil. In a new study, the researchers show that consumption of extra-virgin olive oil protects memory and learning ability and reduces the formation of amyloid-beta plaques and neurofibrillary tangles in the brain -- classic markers of Alzheimer's disease.

The preliminary work for simulating the human brain is already under way

Bits of a protein that builds up in Parkinson’s disease trigger the immune system, causing it to tag them as foreign invaders.

As the HIV/AIDS epidemic approaches its fourth decade, each year brings promising news of pioneering research to alleviate the scourge. Now scientists report a rapid method to access new molecules that could inhibit the virus that causes AIDS.

Mind-body interventions (MBIs) such as meditation, yoga and Tai Chi don't simply relax us; they can 'reverse' the molecular reactions in our DNA which cause ill-health and depression, according to a study.

Brain cancer is often a devastating diagnosis, and scientists have been hunting for mechanisms that could explain the sources of brain tumours, with hopes to also find something that could prevent them.

Researchers have identified a subgroup of neurons in the mouse brain that, upon activation, immediately prompt binge-like eating.

In previous studies, researchers linked infant brain anatomy differences to autism diagnoses at age two. Now they show differences in functional connections between brain regions at 6 months to predict autism at age two.

Multiple biological clocks control the daily rhythms of physiology and behavior in animals and humans. Whether and how these clocks are connected with each other is still a largely open question. A new study now shows that a central clock governs the circadian rhythms in certain cases.

Nitrates, including cardiac medications and food additives, are common headache triggers, mediated by nitric oxide, a potent vasodilator.
