Law Experts: Mobile Health Apps Need More FDA Regulation

July 28, 2014 1:54 pm | by SMU Dedman School of Law | News | Comments

Smartphones and mobile devices are on the cusp of revolutionizing health care, armed with mobile health (“mHealth”) apps capable of providing everything from cardiac measurements to sonograms. While tremendous potential exists to broaden access to medical treatment and control costs, several health law experts say more oversight is needed by the FDA to ensure consumer confidence and safety.

STEM Teachers Learning from Industry

July 28, 2014 1:50 pm | by Emery Dalesio, Associated Press | News | Comments

A small but growing number of science and math teachers aren't spending the summer at the beach or catching up on books, they're toiling at companies, practicing the principles they teach. As American education focuses on closing the gap between the classroom and employers' needs, programs in North Carolina, California and elsewhere are putting teachers temporarily in the workplace.

East Coast Flooding Increasing as Coastal Sea Levels Rise

July 28, 2014 1:47 pm | by NOAA | News | Comments

Eight of the top 10 U.S. cities that have seen an increase in so-called "nuisance flooding"- which causes such public inconveniences as frequent road closures, overwhelmed storm drains and compromised infrastructure- are on the East Coast. This nuisance flooding, caused by rising sea levels, has increased on all three U.S. coasts, between 300 and 925 percent since the 1960s.

Glow in Space is a Hot Bubble in Our Galaxy

July 28, 2014 1:33 pm | by Univ. of Miami | Videos | Comments

A recent study shows that diffuse X-ray background is dominated by the local hot bubble of gas (1 million degrees), with, at most, 40 percent of emission originating within the solar system. The findings should put to rest the disagreement about the origin of the X-ray emission and confirm the existence of the local hot bubble.

Sweet Discovery: Sugar Transporters Key to 'Fuel Crops'

July 28, 2014 1:26 pm | by Berkeley Lab | News | Comments

A powerful new tool that can help advance the genetic engineering of “fuel” crops for clean, green and renewable bioenergy has been developed. Researchers created an assay that enables the identification and characterization of the function of nucleotide sugar transporters, critical components in the biosynthesis of plant cell walls.

Simple Blood Test Can Diagnose Cancer

July 28, 2014 1:15 pm | by Univ. of Bradford | News | Comments

Researchers have devised a simple blood test that can be used to diagnose whether people have cancer or not. The test will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures, such as colonoscopies and biopsies.

Industrial Lead Pollution Beat Explorers to the South Pole

July 28, 2014 9:03 am | by Desert Research Institute | News | Comments

Norwegian explorer Roald Amundsen became the first man to reach the South Pole in December of 1911. More than 100 years later, an international team of scientists have proven that air pollution from industrial activities arrived long before.

Dinos Fell Victim to Perfect Storm of Events

Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say. A fresh study using up-to-date fossil records and improved analytical tools has helped palaeontologists to build a new narrative of the prehistoric creatures' demise, some 66 million years ago.

Slow Walking Speed Can Predict Dementia

July 28, 2014 7:00 am | by Albert Einstein College of Medicine | News | Comments

A study involving nearly 27,000 older adults on five continents found that nearly 1 in 10 met criteria for pre-dementia based on a simple test that measures how fast people walk and whether they have cognitive complaints. People who tested positive for pre-dementia were twice as likely as others to develop dementia within 12 years.
