Some loss of memory is often considered an inevitable part of aging, but new research reveals how some people appear to escape that fate. A study by Massachusetts General Hospital (MGH) investigators examines a remarkable group of older adults whose memory performance is equivalent to that of younger individuals and finds that certain key areas of their brains resemble those of young people.

WASHINGTON - The demand for family caregivers for adults who are 65 or older is increasing significantly, and family caregivers need more recognition, information, and support to fulfill their responsibilities and maintain their own health, financial security, and well-being, says a new report from the National Academies of Sciences, Engineering, and Medicine. Although caregivers' individual circumstances vary, family caregiving can negatively affect caregivers' mental and physical health as well cause economic harm, including loss of income and career opportunities.

HOUSTON - (Sept. 13, 2016) - Scientists at Baylor College of Medicine, the National Institutes of Health and Virginia Tech Carilion Research Institute have discovered a new mechanism in the mouse brain that regulates obesity. The study, which appears in Cell Reports today, shows that this new mechanism can potentially be targeted to treat obesity.

EAST LANSING, Mich. --- Intelligence -- and not just relentless practice -- plays a significant role in determining chess skill, indicates a comprehensive new study led by Michigan State University researchers.

The research provides some of the most conclusive evidence to date that cognitive ability is linked to skilled performance -- a hotly debated issue in psychology for decades -- and refutes theories that expertise is based solely on intensive training.

Does your toddler use a touchscreen tablet? A recent study published in Frontiers in Psychology has shown that early touchscreen use, and in particular actively scrolling the screen, correlates with increased fine motor control in toddlers.

WASHINGTON (September 13, 2016) - Discrimination and bullying experienced by sixth graders who are overweight leads to increased emotional problems by the end of eighth grade, according to new research published in the Journal of Clinical Child & Adolescent Psychology, a journal of the Society of Clinical Child and Adolescent Psychology. The results suggest that to reduce the emotional problems, efforts must not only focus on children and adolescents' weight-loss, but must address the alarmingly disrespectful and exclusionary behavior by their peer group.

A new study by psychologists from the University of Liverpool and the University of Ontario Institute of Technology (UOIT) reveals that collaborating in a group to remember information is harmful.

The research, conducted by Dr Craig Thorley, the University's Department of Psychological Sciences, and Dr Stéphanie Marion, from UOIT's Faculty of Social Science and Humanities, statistically analysed 64 earlier collaborative remembering studies and found that groups recall less than their individual members would if working alone.

Stanford, CA--Using software tools developed by Near Zero, a research group hosted by the Carnegie Institution for Science's Department of Global Ecology, a team of researchers has completed the largest expert survey yet on any energy technology, in this case wind energy.

A flurry of coordinated activity in a brain-spanning network of neurons may sound like the formation of a brilliant new idea, but it is actually the description of a seizure. Understanding why and how this synchronization spreads would be a critical tool in treating severe epilepsy.

TORONTO, Sept. 13, 2016 - Angry, aggressive drivers have much higher odds of being in a motor vehicle collision than those who don't get angry while driving, a new study by Canada's Centre for Addiction and Mental Health (CAMH) shows.

"Even minor aggression, such as swearing, yelling or making rude gestures, can increase the risk of a collision," says lead author Dr. Christine Wickens, scientist in CAMH's Institute for Mental Health Policy Research. The study was published in Transportation Research Part F: Traffic Psychology and Behaviour.

CHAMPAIGN, Ill. -- You don't need a Ph.D. in rhetoric to know that messages from a weak source - a P.T. Barnum-esque carnival barker, for example - typically don't hold much water. But according to new research co-written by a University of Illinois expert in social psychology, even the most spurious of arguments can still reverberate in the public consciousness over time, provided they are delivered by a credible source.

Study Links Altered Brain Chemistry, Behavioral Impairments in Fish Exposed to Elevated CO2Research team studied damselfish behavior and physiology under ocean acidification conditions predicted for year 2300

MIAMI--In a first-of-its-kind study, researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and the ARC Centre of Excellence for Coral Reef Studies at James Cook University showed that increased carbon dioxide concentrations alters brain chemistry that may lead to neurological impairment in some fish.

AMES, Iowa - The morning alarm is more than a signal that it's time to get up - for many people it means it's time to hit the gym. But if exercise is not a habit, that cue from the alarm may trigger a debate over whether to exercise or go back to sleep.

MEDFORD/SOMERVILLE, Mass. (September 13, 2016) --Tufts University researchers have discovered a new technique for generating rapidly-differentiating human neural stem cells for use in a variety of tissue engineering applications, including a three-dimensional model of the human brain, according to a paper published today in Stem Cell Reports. The work could pave the way for experiments that engineer other innervated tissues, such as the skin and cornea, and for the development of human brain models with diseases such as Alzheimer's or Parkinson's.

They have found elevated levels of transglutaminase 2, or TG2, in the brains of mice experiencing chronic stress - an animal model of depression - as well as the prefrontal cortex of depressed people who committed suicide.
