Excess omega-3 fatty acids could lead to negative health effects

Posted: 28 Oct 2013 11:35 AM PDT

A new review suggests that omega-3 fatty acids taken in excess could have unintended health consequences in certain situations, and that dietary standards based on the best available evidence need to be established.

“What looked like a slam dunk a few years ago may not be as clear cut as we thought,” said Norman Hord, associate professor in OSU’s College of Public Health and Human Sciences and a coauthor on the paper.

New class of drug shows promise for treating asthma and COPD

Scientists have developed a new drug (RPL554) that could treat obstructive airway diseases such as asthma and chronic obstructive pulmonary disease (COPD) in two ways at once, according to new research published in The Lancet Respiratory Medicine.

The researchers, led by Professor Clive Page at King’s College London, say RPL554 has the potential to both reverse the narrowing of the airways (bronchodilation) and reduce inflammation quicker and with fewer side effects than current therapies.

Public Wants Labels for Food Nanotech – and They’re Willing to Pay for It

New research from North Carolina State University and the University of Minnesota finds that people in the United States want labels on food products that use nanotechnology – whether the nanotechnology is in the food or is used in food packaging. The research also shows that many people are willing to pay more for the labeling.

Historic Demonstration Proves Laser Communication Possible

Posted: 28 Oct 2013 11:14 AM PDT

In the early morning hours of Oct. 18, NASA’s Lunar Laser Communication Demonstration (LLCD) made history, transmitting data from lunar orbit to Earth at a rate of 622 Megabits-per-second (Mbps). That download rate is more than six times faster than previous state-of-the-art radio systems flown to the moon.
