Washington, Apr 25 : Every brain composes a soundtrack. Its tempo and tone differ, depending on mood and frame of mind. Now, researchers at the US Department of Homeland Security (DHS) believe that the cerebral music can help in dealing with insomnia and fatigue in the aftermath of a stressful experience.

New York  - Every 30 seconds, somewhere in the world, a child dies of malaria, and ending the scourge of the preventable disease is a major development priority, the United Nations Childrens Fund said Friday.

Despite substantial progress in the fight against malaria, especially the increased distribution of insecticide-treated nets, the disease still kills an estimated 1 million people every year, UNICEF said on the eve of World Malaria Day on Saturday.

Washington, Apr 24: A subset of immune cells could make malaria patients vulnerable towards contracting the severe form of the disease and suffer worse symptoms, according to a new study.

Researchers, led by Monash University immunologist Professor Magdalena Plebanski, found that patients with the severe form of malaria have a specific type of cell in their body, which is absent in people with uncomplicated disease.

This type of cell turns off the immune system and can allow the parasite to grow uncontrollably.

Washington, Apr 24: By using a computer-aided detection (CAD) method, radiologists could identify cancerous lung nodules at an early stage, a new study has claimed.

Performed at the University of Maryland Medical Center in Baltimore, MD, the study could boost the chances of survival among cancer patients.

“In our study we identified 88 nodules that were not detected at the time of interpretation but visible in retrospect and were subsequently determined to be lung cancers,” said Joseph Jen-Sho Chen, MD, lead author of the study.
