20 min aerobics/day can dramatically reduce women's diabetes risk

aerobicsWashington, Jan. 15 : Researchers have said women who engaged in at least 150 min/week of aerobic activity and at least 60 min/week of muscle-strengthening activities had the most substantial risk reduction compared with inactive women.

How body's immune system fights off malaria

How body's immune system fights off malariaWashington, Jan 14 : By using a strain of mice that mimics many of the features of the human immune system and can be infected with the most common human form of the malaria parasite, a team of scientists has identified a key host defense mechanism.

New breakthrough brings hope for kidney patients

kidney patientWashington, Jan. 13 - A new study has revealed that certain cells contribute to kidney function decline, making them attractive targets for treatments against kidney failure.

The blood-filtering cells in the kidneys- called podocytes- are critical to kidney function, and kidney failure can occur when as little as about 20 percent to 30 percent of them are lost.

Young kids achieve 90pc of recommended daily physical activity in 11.3 hours

physical activityWashington, Jan 13 - A new study has revealed that preschool-aged children achieve 90 percent of their recommended daily physical activity across their waking hours, typically within a period of 11.3 hours.

Children in the study, ages 3-5, achieved this activity through relatively short bursts of energy expenditure as opposed to the longer and more routine periods of exercise typically exhibited by adults.

How genetic mutations lead to development of Familial Alzheimer's

AlzheimerWashington, Jan 11 - A new research has solved one mystery in the development of Familial Alzheimer's Disease (FAD) - a genetic variant of the disease that affects a small fraction of the Alzheimer's population.

Rensselaer Polytechnic Institute researcher Chunyu Wang and his team follow the trail of two genetic mutations - V44M and V44A - known to cause FAD, and show how the mutations lead to biochemical changes long linked to the disease.
