Cells Can Communicate by Reaching Out and Touching

January 3, 2014 11:14 am | News | Comments

In a finding that directly contradicts the standard biological model of animal cell communication, scientists have discovered that typical cells in animals have the ability to transmit and receive biological signals by making physical contact with each other, even at long distance.

Computer Algorithm Can Turn Off 'Aging' Genes

January 3, 2014 11:06 am | News | Comments

Restricting calorie consumption is one of the few proven ways to combat aging and has been shown to prolong lifespan in yeast, worms, flies, monkeys, and, in some studies, humans. Now, researchers have developed a computer algorithm that predicts which genes can be "turned off" to create the same anti-aging effect.

Shingles Linked to Increased Stroke Risk

January 3, 2014 9:06 am | News | Comments

Having shingles, a viral infection that causes a painful rash, may increase the risk of having a stroke years later, according to new research.                              

Flexibile, Versatile Cell Division Has Cancer Implications

January 2, 2014 12:24 pm | News | Comments

New research has shown that cells demonstrate remarkable flexibility and versatility when it comes to how they divide– a finding with potential links to the underlying causes of many cancers.

Scientists Uncover Detailed Picture of Muscular Dystrophy Defect

January 2, 2014 12:04 pm | News | Comments

Scientists have revealed an atomic-level view of a genetic defect that causes a form of muscular dystrophy, myotonic dystrophy type 2, and have used this information to design drug candidates with potential to counter those defects.      

High Good, Low Bad Cholesterol is Healthy for the Brain

January 2, 2014 11:52 am | News | Comments

High levels of “good” cholesterol and low levels of “bad” cholesterol are correlated with lower levels of the amyloid plaque deposition in the brain that is a hallmark of Alzheimer’s disease, researchers have found.          

Imaging Technology Could Unlock Mysteries of RSV

January 2, 2014 11:34 am | News | Comments

A new technique for studying the structure of the RSV virion and the activity of RSV in living cells could help researchers unlock the secrets of the virus, including how it enters cells.

December 31, 2013 4:33 pm | by MARILYNN MARCHIONE - AP Chief Medical Writer - Associated Press | News | Comments

Researchers say vitamin E might slow the progression of mild-to-moderate Alzheimer's disease — the first time any treatment has been shown to alter the course of dementia at that stage.                   

Body Clock May be to Blame When Tots Fight Sleep

December 30, 2013 12:27 pm | by LAURAN NEERGAARD - AP Medical Writer - Associated Press | News | Comments

When youngsters continually struggle to fall asleep at night, new research suggests maybe their body clock doesn't match their bedtime. But that doesn't mean tots should be up at all hours.                

Nicotine Exploits COPI to Foster Addiction

December 30, 2013 12:00 pm | Videos | Comments

A study in The Journal of General Physiology helps explain how nicotine exploits the body's cellular machinery to promote addiction. The findings could lead to new therapies to help people quit smoking. According to the Center for Disease Control and Prevention, tobacco accounts for the greatest number of preventable deaths worldwide by any single agent. 

Testosterone In Male Songbirds May Enhance Desire To Sing But Not Song Quality

December 30, 2013 10:23 am | News | Comments

Researchers at The Johns Hopkins University have found that introducing testosterone in select areas of a male canary’s brain can affect its ability to successfully attract and mate with a female through birdsong. They also found that enhancing song activity based on testosterone in one brain area can change the size of a separate brain area that regulates song quality.

This research has important implications for disorders in which social information processing is disrupted, including autism spectrum disorder.

New Study Brings Scientists Closer to the Origin of RNA

December 30, 2013 9:57 am | News | Comments

One of the biggest questions in science is how life arose from the chemical soup that existed on early Earth. One theory is that RNA, a close relative of DNA, was the first genetic molecule to arise around 4 billion years ago, but in a primitive form that later evolved into the RNA and DNA molecules that we have in life today. New research shows one way this chain of events might have started.

New Invasive Plant Parasitic Nematode in Europe

December 30, 2013 9:33 am | News | Comments

Following its recent synonymisation with Meloidogyne ulmi, a species known to parasitize elm trees in Europe, it has become clear that M. mali has been in the Netherlands for more than fifty years. Evidences given by the authors suggest that M. mali was probably introduced during the breeding program on Elms against the Dutch Elm Disease (DED).

Genetic Background of Sporadic ALS in the Chinese Han Population

December 30, 2013 9:13 am | News | Comments

A previous study of European Caucasian patients with sporadic amyotrophic lateral sclerosis demonstrated that a polymorphism in the microtubule-associated protein Tau (MAPT) gene was significantly associated with sporadic amyotrophic lateral sclerosis pathogenesis. To examine this in a different population, researchers investigated the association of the MAPT gene with sporadic amyotrophic lateral sclerosis in the Chinese Han population.
