Public health researchers from The University of Manchester have found single dietary interventions are not effective at increasing fruit and vegetable consumption among overweight children and will not halt the global epidemic in childhood ...
What happens to our cognitive abilities as we age? Traditionally it is thought that age leads to a steady deterioration of brain function, but new research in Topics in Cognitive Science argues that older brains may take longer to process ...
Young adults are at particularly high risk for excessive weight gain. Although weight gain intervention for young adults attending two- or four-year colleges has been studied extensively, there has been little research into effective ...
An experiment by scientists at the University of Granada, Spain, shows a high-protein diet increases the chance of developing kidney stones and other renal diseases High-protein diets, like the popular Dr. Dukan diet, increase the ...
New research finds significantly higher levels of infectious pathogens in water from faucet taps with aerators compared to water from deeper in the plumbing system. Contaminated water poses an increased risk for infection in ...
From the world of nanotechnology we've gotten electronic skin, or e-skin, and electronic eye implants or e-eyes. Now we're on the verge of electronic whiskers. Researchers with Berkeley Lab and the University of California (UC) Berkeley ...
