Elevating women's status lowers dependence on solid fuels

A new research paper finds that in countries where gender inequalities are most pronounced, women are much more likely to be exposed to solid fuel -- including burning from wood, crop wastes, charcoal, and dung -- and its negative consequences.

Elevated blood pressure not a high mortality risk for elderly with weak grip

A study of nearly 7,500 Americans age 65 or older suggests that elevated blood pressure is not related to high mortality risk among people in that age group with weak grip strength.

Alcohol use in veterans with schizophrenia less common than thought; no level safe

US veterans who are being treated for schizophrenia are much less likely to drink any alcohol than the general population. But when they do misuse alcohol, it leads to worsening of their symptoms.

New method to 'fingerprint' HIV developed

A method to analyze the glycan shield on HIV's protective outer glycoprotein has been developed as a potential HIV vaccine candidate, report scientists.

Potential drugs and targets for brain repair

Researchers have discovered drugs that activate signaling pathways leading to specific adult brain cell types from stem cells in the mouse brain, according to a new study. The results may open new avenues for drug development aimed at treatment of degenerative brain disorders.

Unraveling the functional diversity of longevity gene SIRT1

While the search for elixir of life has captivated human imagination for millennia, researchers around the world have put in efforts to extend healthy lifespan and reduce the burden of morbid diseases in an increasingly aging population. Researchers have now identified a control mechanism within a longevity gene, which is key to unraveling its functional diversity and is likely to boost efforts at designing specific pharmacological agents.

Lead exposure in childhood linked to lower IQ, lower status jobs, as adults

A long-term study of 565 children who grew up in the era of leaded gasoline has shown that their exposure to the powerful neurotoxin may have led to a loss of intelligence and occupational standing by the time they reached age 38. Ninety-four percent of the children exceeded today's reference value of 5 micrograms of lead per deciliter of blood. For each 5-microgram increase in blood lead, a person lost about 1.5 IQ points.

Malaria parasites 'walk through walls' to infect humans

Researchers have identified proteins that enable deadly malaria parasites to 'walk through cell walls' -- a superpower that was revealed using the Institute's first insectary to grow human malaria parasites. The research has identified two parasite proteins that are the key to this superpower. The proteins could be targeted to develop much-needed antimalarial drugs or vaccines.

Vitamin D, calcium supplementation among older women does not significantly reduce risk of cancer

Among healthy postmenopausal women, supplementation with vitamin D3 and calcium compared with placebo did not result in a significantly lower risk of cancer after four years, according to a study.

Celiac disease: Not enough evidence for screening

The current evidence is insufficient to assess the balance of benefits and harms of screening for celiac disease in asymptomatic persons, the US Preventive Services Task Force has concluded.
