Lasers stimulate stem cells and reduce heart scarring after heart attack, study suggests (August 12, 2011) -- New research shows that "shining" bone marrow stem cells with a laser encourages these cells to migrate to the heart to facilitate the healing process. If applied to these cells a few hours after a heart attack, the scarring that weakens the heart muscle can be reduced by up to 80 percent. ... > full story
Drug development in the blink of an eye (August 12, 2011) -- The development of drugs for brain-related conditions is not an efficient process. A key reason for this is a lack of preclinical tests that accurately predict drug efficacy and detect unwanted side effects. But now, researchers have developed a new preclinical approach that they hope can be used alongside current strategies to guide more efficient drug development for brain-related conditions. ... > full story
Possible therapeutic target for depression and addiction identified (August 12, 2011) -- Researchers have identified an important part of the pathway through which stress affects mood and motivation for drugs. The finding may prove useful in humans by providing new potential targets for drugs to treat problems related to stress. ... > full story
Low vitamin D linked to earlier first menstruation (August 12, 2011) -- A study links low vitamin D in young girls with early menstruation, which is a risk factor for a host of health problems for teen girls as well as women later in life. ... > full story
Human-cell-derived model of amyotrophic lateral sclerosis provides a new way to study the majority of cases (August 12, 2011) -- For decades, scientists have studied a laboratory mouse model that develops signs of the paralyzing disease amyotrophic lateral sclerosis (ALS) as they age. Researchers have now developed a new model of ALS, one that mimics sporadic ALS, which represents about 90 percent of all cases. ... > full story
Resistance training can help smokers kick the habit, according to study (August 12, 2011) -- Resistance training, or weight lifting, can do more than just build muscle: it may also help smokers kick the habit, say researchers. ... > full story
Research reveals genetic link to human intelligence (August 12, 2011) -- New research provides the first direct biological evidence for a genetic contribution to people's intelligence. Previous studies on twins and adopted people suggested that there is a substantial genetic contribution to thinking skills, but this new study is the first to find a genetic contribution by testing people's DNA for genetic variations. ... > full story
'Good fat' most prevalent in thin children (August 12, 2011) -- Researchers have shown that a type of "good" fat known as brown fat occurs in varying amounts in children -- increasing until puberty and then declining -- and is most active in leaner children. ... > full story
Combination of existing safety checks could greatly reduce radiotherapy errors, study suggests (August 12, 2011) -- A combination of several well-known safety procedures could greatly reduce patient-harming errors in the use of radiation to treat cancer, according to a new study. ... > full story
Increased light may moderate fearful reactions (August 12, 2011) -- Biologists and psychologists know that light affects mood, but a new study indicates that light may also play a role in modulating fear and anxiety. ... > full story
Engineers redefine how the brain plans movement (August 12, 2011) -- New neurological measurement technologies and algorithms are allowing researchers a more complete look into how the brain functions. Engineers are using these tools to better understand how the brain prepares to initiate a body motion and why sometimes we react more quickly than others. ... > full story
Scientists copy the ways viruses deliver genes (August 12, 2011) -- Scientists have mimicked the ways viruses infect human cells and deliver their genetic material. The research hopes to apply the approach to gene therapy -- a therapeutic strategy to correct defective genes such as those that cause cancer. ... > full story
