Hatha Yoga Boosts Brain Function in Older Adults

August 19, 2014 2:00 pm | by Univ. of Illinois | News | Comments

Practicing hatha yoga three times a week for eight weeks improved sedentary older adults’ performance on cognitive tasks that are relevant to everyday life, researchers report. The findings involved 108 adults between the ages of 55 and 79 years of age, 61 of whom attended hatha yoga classes. The others met for the same number and length of sessions and engaged in stretching and toning exercises instead of yoga.

'Lightning Rods' Channel Electricity Through Air

August 19, 2014 2:00 pm | by Univ. of Arizona | News | Comments

By zapping the air with a pair of powerful laser bursts, researchers have created highly focused pathways that can channel electricity through the atmosphere. The technique can potentially direct an electrical discharge up to 33 feet away or more, shattering previous distance records for transmitting electricity through air.

U.S. Coal in Asia Could Slash Emissions

August 19, 2014 2:00 pm | by Duke Univ. | News | Comments

Under the right scenario, exporting U.S. coal to power plants in South Korea could lead to a 21 percent drop in greenhouse gas emissions compared to burning the fossil fuel at plants in the U.S. Despite the large amount of emissions produced by shipping the coal, total emissions would drop because of the superior energy efficiency of South Korea’s newer coal-fired power plants.

Artificial Cells Act Real

August 19, 2014 7:00 am | by Weizmann Institute | News | Comments

Scientists have created an artificial, network-like cell system that is capable of reproducing the dynamic behavior of protein synthesis. This achievement is not only likely to help gain a deeper understanding of basic biological processes, but it may pave the way toward controlling the synthesis of both naturally occurring and synthetic proteins for a host of uses.

Long-lasting Joint Lubrication Mimics Nature

August 19, 2014 7:00 am | by Johns Hopkins Medicine | News | Comments

By finding a way to bind a slippery molecule naturally found in the fluid that surrounds healthy joints, researchers have engineered surfaces that have the potential to deliver long-lasting lubrication at specific spots throughout the body. The finding could eventually offer a new way to ease the pain of arthritic joints, keep artificial joints working smoothly or even make contact lenses more comfortable.
