A clear link between adherence to a healthy diet and reduced mortality risk from cardiovascular disease (CVD), cancer, and other diseases has been established in a new study on a low-income population in the south east of the United States (US). The study, on adherence to the Dietary Guidelines for Americans (DGA), was led by Dr Wei Zheng, with colleagues from his institution of Vanderbilt University, Nashville, as well as the International...

A new study has demonstrated that a protein called Niemann-Pick C1 (NPC1) is critical for the Ebola virus to infect a host. The study, published in the May/June issue of mBio, the online open-access journal of the American Society for Microbiology, suggests that drugs that block NPC1 could be used to treat this deadly disease.

Patients with heart failure who also suffer from moderate to severe depression have a five-fold increased risk of all-cause mortality in the year following discharge from hospital, compared to those who were not or mildly depressed. This increased risk is independent of severity of heart disease or presence of co-morbidities, which have previously been proposed as reasons for the known association of depression with mortality following heart...

It looks like a Slinky suspended in motion. Yet this photonics advancement – called a metamaterial hyperlens – doesn’t climb down stairs. Instead, it improves our ability to see tiny objects. Described in a research paper published today by the journal Nature Communications, the hyperlens may someday help detect some of the most lethal forms of cancer.

In adolescents, television commercials for food lead to greater stimulation in the brain regions associated with pleasure and reward when compared to non-food commercials, according to a new study in the journal Cerebral Cortex. This stimulation is significantly greater in overweight adolescents than in those with healthy weight. Moreover, in the overweight adolescents this reward- related stimulation in response to watching others eating in...
