Washington, Mar 31 : Killing mosquitoes in their water-borne larval stage of development can effectively control malaria in urban areas, according to a study.

However, most interventions target adult mosquitoes, which can carry the parasite.

Washington, Mar 31 : An international team of researchers have developed a novel radiation-free technique that detects and eliminates breast cancer tumours.

The team including researchers from California Institute of Technology (Caltech), the Israel Institute of Technology (Technion) and the Cedars-Sinai Medical Centre have shown that combining a compound known as a gallium corrole with a protein carrier can effectively detect and remove tumours with fewer side effects.

Washington, Mar 31 : A new study in the U. S. has found a link between an increased number of birth defects in children of women who got pregnant in spring or summer and elevated levels of pesticides in surface water across the country.

Studying all 30.1 million births, which occurred in the U. S. between 1996 and 2002, the researchers found that women whose last menstrual period occurred in April, May, June or July were at increased risk for delivering infants with birth defects.

They also found that this period of increased risk correlated with elevated levels of nitrates, atrazine and other pesticides in surface water across the country.

Washington, Mar 31 : A new study has shown that dietary supplementation with lipoic acid, a natural compound found at low levels in red meat and green leafy vegetables, can significantly reduce triglycerides, a key risk factor in cardiovascular disease.
