Berkeley Lab study links healthy micronutrient intake with reduced DNA fragmentation
A new study led by scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) found that a healthy intake of micronutrients is strongly associated with improved sperm DNA quality in older men. In younger men, however, a higher intake of micronutrients didn’t improve their sperm DNA. (more…)
UMN study shows eating less is about reduced desire as well as willpower
MINNEAPOLIS / ST. PAUL — New research from the University of Minnesota’s Carlson School of Management suggests learning how to stop enjoying unhealthy food sooner may play a pivotal role in combating America’s obesity problem. The research, published in the Journal of Consumer Research, explores how satiation, defined as the drop in liking during repeated consumption, can be a positive mechanism when it lowers the desire for unhealthy foods.
“When people talk about self-control, they really imply that self-control is willpower and that some people have it and others don’t when facing a tempting treat,” says Joseph Redden, an assistant professor of marketing at the Carlson School and lead author of the ‘Healthy Satiation: The Role of Decreasing Desire in Effective Self-Control.’ “In reality, nearly everyone likes these treats. Some people just stop enjoying them faster and for them it’s easier to say no.” (more…)
Adolescents who smoke cigarettes or use alcohol or marijuana may be at greater risk for subsequent abuse of prescription opioids as young adults, according to a new study by Yale School of Medicine.
The researchers believe their findings are the first to demonstrate that early alcohol, cigarette, and marijuana use are all associated, to varying degrees, with a two- to-three times greater likelihood of subsequent abuse of prescription opioids. The study appears online in the Journal of Adolescent Health. (more…)
Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin? (more…)

Discovery may hold key to restoring speech after paralysis
Diagnosed with Lou Gehrig’s disease at 21, British physicist Stephen Hawking, now 70, relies on a computerized device to speak. Engineers are investigating the use of brainwaves to create a new form of communication for Hawking and other people suffering from paralysis.

Scientists at UCLA and the Technion, Israel’s Institute of Technology, have unraveled how our brain cells encode the pronunciation of individual vowels in speech.
Published in the Aug. 21 edition of the journal Nature Communications, the discovery could lead to new technology that verbalizes the unspoken words of people paralyzed by injury or disease. (more…)
COLUMBIA, Mo. – Despite differences in rituals and beliefs among the world’s major religions, spirituality often enhances health regardless of a person’s faith, according to University of Missouri researchers. The MU researchers believe that health care providers could take advantage of this correlation between health – particularly mental health – and spirituality by tailoring treatments and rehabilitation programs to accommodate an individual’s spiritual inclinations.
“In many ways, the results of our study support the idea that spirituality functions as a personality trait,” said Dan Cohen, assistant teaching professor of religious studies at MU and one of the co-authors of the study. “With increased spirituality people reduce their sense of self and feel a greater sense of oneness and connectedness with the rest of the universe. What was interesting was that frequency of participation in religious activities or the perceived degree of congregational support was not found to be significant in the relationships between personality, spirituality, religion and health.” (more…)
AUSTIN, Texas — An inexpensive antifungal drug, thiabendazole, slows tumor growth and shows promise as a chemotherapy for cancer. Scientists in the College of Natural Sciences at The University of Texas at Austin made this discovery by exploiting the evolutionary relatedness of yeast, frogs, mice and humans. (more…)
