Calcium Linked to Boost in Heart Attack Risk

millions of people take calcium supplements to boost bone health and ward off osteoporosis, New Zealand researchers say the supplements have little effect on bone strength and contribute to a small increase in the risk for heart attack among older people.

Vaccine Scares May Do More Harm Than Previously Believed To A Population’s ‘Herd Immunity’

Public immunization efforts may be much more sensitive than previously realized to small changes in the perceived costs or risks of vaccination, scientists at Harvard University report this week. In some cases, the spread of vaccine avoidance via social networks can make the difference between a minor, localized outbreak and an epidemic four times as […]

New Approach To Alzheimer’s Therapy

Researchers from the German Centre for Neurodegenerative Diseases (DZNE) and the Ludwig-Maximilians-Universität (LMU) in Munich have shown that the ADAM10 protein can inhibit the formation of beta-amyloid, which is responsible for Alzheimer’s disease. ADAM10 acts like a pair of molecular scissors to cut the protein from which beta-amyloid is formed, effectively preventing the formation of […]

Stem cell therapy can help heal the hearts of people who have had heart attacks

A new University of Miami experiment with pigs raises hope that stem cell therapy can help heal the hearts of people who have had heart attacks. It might even help heal livers, kidneys and other damaged organs. A medical research team led by University of Miami doctors injected stem cells into the hearts of pigs […]

Multifunctional Nanoparticle Enables New Type Of Biological Imaging

Spotting a single cancerous cell that has broken free from a tumor and is traveling through the bloodstream to colonize a new organ might seem like finding a needle in a haystack. But a new imaging technique from the University of Washington is a first step toward making this possible. UW researchers have developed a […]

Extended Daylight Hours Influence Teens’ Sleeping Patterns

In the spring, later sunset and extended daylight exposure delay bedtimes in teenagers, according to researchers at Rensselaer Polytechnic Institute’s Lighting Research Center (LRC). “Biologically, this increased exposure to early evening light in the spring delays the onset of nocturnal melatonin, a hormone that indicates to the body when it’s nighttime,” explains Mariana Figueiro, Ph.D., […]
