July 28, 2014 8:47 am | by Univ. of Edinburgh | News | Comments

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.  

'Alarm Clock' Could Awaken Immune System to Fight Cancer

July 25, 2014 1:26 pm | by Norris Cotton Cancer Center | News | Comments

Researchers are exploring ways to wake up the immune system so it recognizes and attacks invading cancer cells. Tumors protect themselves by tricking the immune system into accepting everything as normal, even while cancer cells are dividing and spreading. One pioneering approach uses nanoparticles to jumpstart the body's ability to fight tumors.

Total Darkness at Night Key to Breast Cancer Therapy

July 25, 2014 1:10 pm | by Tulane Univ. | News | Comments

Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug. The study is the first to show that melatonin is vital to the success of tamoxifen in treating breast cancer.

Is Europe Putting Cancer Research at Risk?

July 25, 2014 9:31 am | by European Society for Medical Oncology | News | Comments

The European Society for Medical Oncology (ESMO) has expressed concern that the proposed EU General Data Protection Regulation could make cancer research impossible and add a significant burden to both doctors and cancer patients.               

Ruling on Antibiotics in Livestock Reversed

July 25, 2014 9:04 am | by Associated Press | News | Comments

The U.S. Food and Drug Administration isn't required to hold public hearings to evaluate the health risks of widespread use of antibiotics in animal feed, a federal appeals court ruled Thursday. The decision by the 2nd U.S. Circuit Court of Appeals reversed a ruling in 2012 by a district court that sided with several health and consumer organizations that sued the FDA after the agency decided against holding the hearings.

Antioxidant Biomaterial Promotes Healing

July 25, 2014 7:00 am | by Northwestern Univ. | News | Comments

For the first time ever, researchers have created a biodegradable biomaterial that is inherently antioxidant. The material can be used to create elastomers, liquids that turn into gels, or solids for building devices that are more compatible with cells and tissues.

July 25, 2014 7:00 am | by Julia Evangelou Strait, Washington Univ. in St. Louis | News | Comments

Researchers have uncovered a way the malaria parasite becomes resistant to an investigational drug. The discovery is also relevant for other infectious diseases including bacterial infections and tuberculosis.                         

Only 8.2% of DNA is ‘Functional’

July 25, 2014 7:00 am | by Oxford Univ. | News | Comments

Only 8.2 percent of human DNA is likely to be doing something important, or is “functional.” This figure is very different from one given in 2012, when some scientists involved in the ENCODE project stated that 80 percent of our genome has some biochemical function.

Modern Cells Still Perform Ancient Reactions

July 24, 2014 3:01 pm | by Univ. of East Anglia | News | Comments

Parts of the primordial soup in which life arose have been maintained in our cells today. Research reveals how cells in plants, yeast and very likely also in animals still perform ancient reactions thought to have been responsible for the origin of life- some four billion years ago.

Glucose Helps Alaska Frogs 'Overwinter' to Survive

July 24, 2014 7:00 am | by Univ. of Fairbanks | Videos | Comments

Repeated freezing and thawing might not be good for the average steak, but each fall it might help wood frogs prepare to survive Alaska’s winter cold. Frogs prevent the freeze-pop effect by packing their cells with glucose, a kind of sugar that reduces drying and stabilizes cells, a process scientists call cryoprotection.

Our Genes are Disadvantageous in Changing Environment

July 24, 2014 7:00 am | by Univ. of Exeter | News | Comments

Breaking the mold of inherited family characteristics could help you survive in a fast-changing world, scientists have discovered. A new study has shown that such slowly changing genes are only beneficial in a steady environment.

July 24, 2014 7:00 am | by Univ. of California, Riverside | News | Comments

Fragile X syndrome (FXS) is a genetic disorder that causes obsessive-compulsive and repetitive behaviors, and other behaviors on the autistic spectrum, as well as cognitive deficits. It is the most common inherited cause of mental impairment and the most common cause of autism. Now, biomedical scientists have published a study that sheds light on the cause of these behaviors.
