MINNEAPOLIS – People who develop a type of irregular heartbeat common in old age called atrial fibrillation may also be more likely to develop problems with memory and thinking, according to new research published in the June 5, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.

CHAMPAIGN, Ill. — Researchers report that a single, 20-minute session of Hatha yoga significantly improved participants' speed and accuracy on tests of working memory and inhibitory control, two measures of brain function associated with the ability to maintain focus and take in, retain and use new information. Participants performed significantly better immediately after the yoga practice than after moderate to vigorous aerobic exercise for the same amount of time.
SAN FRANCISCO, June 5, 2013 -- As Father's Day draws near, psychologist Jeff Cookston says dads should ask their children for a little more feedback than they might get with the yearly greeting card.
Just being a good parent may not be good enough, said Cookston, professor of psychology at San Francisco State University, who has studied fatherhood extensively. "There's a need for fathers to sometimes say to their kids, 'How am I doing? Am I the dad you need me to be?'"
Forget to turn off the lights before leaving the apartment? No problem. Just raise your hand, finger-swipe the air, and your lights will power down. Want to change the song playing on your music system in the other room? Move your hand to the right and flip through the songs.
University of Washington computer scientists have developed gesture-recognition technology that brings this a step closer to reality. Researchers have shown it's possible to leverage Wi-Fi signals around us to detect specific movements without needing sensors on the human body or cameras.
MRI may be an effective way to diagnose mental illnesses such as bipolar disorder, according to experts from the Icahn School of Medicine at Mount Sinai. In a landmark study using advanced techniques, the researchers were able to correctly distinguish bipolar patients from healthy individuals based on their brain scans alone. The data are published in the journal Psychological Medicine.
A team of researchers from Emory, University of Miami and Scripps Research Institute has identified a compound that can reduce PTSD-like symptoms in mice after they are exposed to stress. The discovery could lead to a treatment given to people shortly after a traumatic event, aimed at preventing possible PTSD (post-traumatic stress disorder).
The results are scheduled for publication Wednesday in the journal Science Translational Medicine.
When injected into mice immediately following a traumatic event, a new drug prevents the animals from developing memory problems and increased anxiety that are indicative of post-traumatic stress disorder (PTSD).
Howard Hughes Medical Institute scientists utilized mouse studies to suggest that a receptor called Oprl1 is altered in mice with PTSD-like symptoms. They then worked with a group at the Scripps Research Institute who had previously developed the Oprl1-targeted drug to examine its effects on fear memory modulation.
EUGENE, Ore. -- (June 5, 2013) -- A gene linked to autism spectrum disorders that was manipulated in two lines of transgenic mice produced mature adults with irreversible deficits affecting either learning or social interaction.
The findings, published in the May 29 issue of the Journal of Neuroscience, have implications for potential gene therapies but they also suggest that there may be narrow windows of opportunity to be effective, says principal investigator Philip Washbourne, a professor of biology and member of the University of Oregon's Institute of Neuroscience.
The first study drew the conclusion that people cooperate more if they are forced to make decisions when pressed for time. The research group (Rand et al.) let the test subjects make decisions under pressure on social dilemmas. They found that the decisions made at the time were more oriented towards cooperation. The conclusion was that decisions under pressure that build on intuition promote cooperation. It has gotten a lot of attention and aroused a great deal of discussion.
The World Health Organization lists shift work as a potential carcinogen, says Erik Herzog, PhD, Professor of Biology in Arts & Sciences at Washington University in St. Louis. And that's just one example among many of the troubles we cause ourselves when we override the biological clocks in our brains and pay attention instead to the mechanical clocks on our wrists.
CINCINNATI – As pediatric specialists become increasingly aware that surgical anesthesia may have lasting effects on the developing brains of young children, new research suggests the threat may also apply to adult brains.
Researchers from Cincinnati Children's Hospital Medical Center report June 5 the Annals of Neurology that testing in laboratory mice shows anesthesia's neurotoxic effects depend on the age of brain neurons – not the age of the animal undergoing anesthesia, as once thought.
Researchers in the University of Minnesota's College of Science and Engineering have developed a new noninvasive system that allows people to control a flying robot using only their mind. The study goes far beyond fun and games and has the potential to help people who are paralyzed or have neurodegenerative diseases.
A new study from the University of British Columbia helps explain how people become obsessed with forbidden pleasures.
The study, which will appear in an upcoming edition of Cognitive, Affective and Behavioral Neuroscience journal, shows that when people are forbidden from something, it takes on a new level of focus.
Researchers at Boston University School of Medicine (BUSM) have uncovered important clues about a biochemical pathway in the brain that may one day expand treatment options for schizophrenia. The study, published online in the journal Molecular Pharmacology, was led by faculty within the department of pharmacology and experimental therapeutics at BUSM.
Teacher collaboration, professional communities improve many elementary school students' math scores
WASHINGTON, DC, June 5, 2013 — Many elementary students' math performance improves when their teachers collaborate, work in professional learning communities or do both, yet most students don't spend all of their elementary school years in these settings, a new study by UNC Charlotte researchers shows. The U.S. Department of Education funded the study, which the journal Sociology of Education recently published.
