Tempe, Ariz. -- Male students in undergraduate introductory biology courses are outperforming females at test time, but it may be due to how exams are designed rather than academic ability. In addition, high socioeconomic status students are performing better than lower-status students on those same tests.

Simon Fraser University researchers hope that a brain vital-sign test becomes as routine during a doctor's check-up as taking a blood pressure or heart rate measurement.

SFU researchers, led by professor Ryan D'Arcy with partners from the Mayo Clinic, Sheba Medical Centre in Israel and local high-tech company HealthTech Connex Inc., are developing a more accessible means to monitor brain health.

The relentless desire by mice to run on cage "exercise" wheels has helped explain at a molecular level how exercise benefits a mammal's brain.

Scientists from NYU Langone Medical Center behind the related research say their latest findings not only add evidence to the value of exercise for humans looking to keep their brains fit, but also suggest new strategies to ward off neurological disease.

An online study of male undergraduates shows that more than half of study participants on intercollegiate and recreational athletic teams - and more than a third of non-athletes - reported engaging in sexual coercion, including rape. The increased risk of sexual coercion by athletes was linked to "traditional" beliefs about women and a higher belief in rape "myths," which are used to justify sexual assault.

A dietary supplement containing a blend of thirty vitamins and minerals--all natural ingredients widely available in health food stores--has shown remarkable anti-aging properties that can prevent and even reverse massive brain cell loss, according to new research from McMaster University.

It's a mixture scientists believe could someday slow the progress of catastrophic neurological diseases such as Alzheimer's, ALS and Parkinson's.

ANN ARBOR, Mich. -- Call them the Brain Generation -- the tens of thousands of college and graduate students working toward degrees in neuroscience, and the high school students who want to join them someday.

They've grown up in a time when exciting new discoveries about the brain come out every day, fueled by a revolution in scientific tools during their short lives. And that has fueled a boom in students choosing to work toward a neuroscience degree.

Children with Attention Deficit Hyperactivity Disorder (ADHD) often display behaviours that are inappropriate for the situation in which they are in. They might move around in the classroom during a lesson, or talk non-stop and interrupt others' conversations. ADHD is a neuro-developmental disorder that affects about 5% of children. Despite a considerable amount of research over many years, the causes of ADHD are still debated.

Researchers use accelerators to coax the electron into performing a wide range of tricks to enable medical tests and treatments, improve product manufacturing, and power breakthrough scientific research. Now, they're learning how to coax the same tricks out of the electron's antimatter twin - the positron - to open up a whole new vista of research and applications.

In a large study examining a nationally representative survey of American adults from 1973 to 2014, researchers from Florida Atlantic University, San Diego State University and Widener University have found that same-sex sexual experience has doubled, and acceptance of same-sex sexual experience has quadrupled.

SAN DIEGO, Calif. (June 1, 2016)--Reflecting rapidly changing cultural attitudes in the United States toward sexuality, a new study finds that the percentage of adults who have had sex with people from their same gender has doubled since the 1990s. The study also found that acceptance of same-sex sexuality has increased among all generations, with Millennials the most accepting.

DURHAM, N.C. -- A research team at Duke University has discovered a potential new class of small-molecule drugs that simultaneously block two sought-after targets in the treatment of pain.

These proof-of-concept experiments, published June 1 in Scientific Reports, could lead to the development of a new drug to treat conditions including skin irritation and itching, headaches, jaw pain, and abdominal pain stemming from the pancreas and colon.

People with Alzheimer's disease could benefit from earlier diagnosis if a long-term memory test combined with a brain scan were carried out, a study suggests.

Scientists say testing memory over a long timescale reveals early deficits in the brain's ability to remember. These are not detected by checks for short-term forgetfulness, which is the current practice for diagnosis.

The study also suggests that a brain scan in combination with a memory test could identify early abnormalities in the brain activity of Alzheimer's patients that would be otherwise undetected.

Scientists from RIKEN in Japan have discovered that acrolein--a toxic substance produced in cells during times of oxidative stress--in fact may play a role in preventing the process of fibrillation, an abnormal clumping of peptides that has been associated with Alzheimer's disease and other neural diseases. The key to this new role is a chemical process known as 4+4 cycloaddition, where two molecules with "backbones" made up of four-atom chains come together to form a ring-like structure with eight atoms.

Studies of young people's perceived values of learning has resulted in a theoretical framework that can form the basis for further discussions and means to develop and understand education. The framework is the result of a recent dissertation from Umeå University.

New research by the University of Stirling has found that men who are perceived low in masculinity can significantly increase this by applying deodorant, but that this is not the case for men who already have high levels of masculinity.

The study investigated what effect wearing deodorant has on assessing masculinity and femininity. 130 female and male participants rated facial masculinity and femininity using photographs and a further 239 men and women rated odour samples of 40 opposite sex individuals.
