Researchers have found that male and female brains respond in remarkably different ways to high-fat meals. Those differences in the brain lead to greater inflammation and increased health risks in males that indulge on fatty foods in comparison to females, a new study in mice shows. The findings in Cell Reports may help to explain observed differences in obesity outcomes between women and men - premenopausal women carrying extra weight fare better than men do - and suggest that dietary advice should be made more sex-specific.

Choosing between two good things can be tough. When animals must decide between feeding and mating, it can get even trickier. In a discovery that might ring true even for some humans, researchers have shown that male brains – at least in nematodes – will suppress the ability to locate food in order to instead focus on finding a mate.
The results in Current Biology may point to how subtle changes in the brain's circuitry dictate differences in behavior between males and females.
Myths about the brain are common among teachers worldwide and are hampering teaching, according to new research.
Teachers in the UK, Holland, Turkey, Greece and China were presented with seven so-called 'neuromyths' and asked whether they believe them to be true.
EAST LANSING, Mich. --- Despite the growing popularity of using computer simulation to help teach college anatomy, students learn much better through the traditional use of human cadavers, according to new research that has implications for health care.
Cary Roseth, associate professor of educational psychology at Michigan State University, said the study suggests cadaver-based instruction should continue in undergraduate human anatomy, a gateway course to medical school, nursing and other health and medical fields.
October 16, 2014 – Families of patients with mild traumatic brain injury (TBI) may expect them to return to normal quickly—after all, it's "just a concussion." But mild TBI can have a lasting impact on families as well as patients, according to a review in the November issue of American Journal of Nursing.

Although progress has been made in recent years, the matter of youth suicide in Quebec still needs to be more effectively addressed. In fact, a new study in the Canadian Journal of Psychiatry shows that more lives could be saved through early detection and increased public awareness and information sharing among professionals.
ANN ARBOR—Adults over 50 who feel comfortable about aging are more proactive in getting preventive health care services, a new University of Michigan study found.
Sometimes, the older population does not visit their doctor because they believe that physical and mental declines typify old age, says Eric Kim, a U-M doctoral student in clinical psychology. They think that lifestyle changes will not make a difference, making them less likely to seek preventive care. This is not true and also not a healthy mindset, he says.
Scientists have shown for the first time that when insect larvae follow a leader to forage for food, both leaders and followers benefit, growing much faster than if they are in a group of only leaders or only followers. The work gives new insight into why such social relationships evolve in insects, and why they are maintained.
PHILADELPHIA—A perspective piece in this week's issue of the New England Journal of Medicine from a student at the University of Pennsylvania's Perelman School of Medicine addresses the evolution of diversity in medical education. "It's not a numbers game anymore," says author Mark A. Attiah, a medical student pursuing both a Master's in translational research and bioethics. "Diversity is a mindset that extends into the classroom and the hospital."
TORONTO, Oct 15, 2014 – Few topics can prove more divisive than religion, with some insisting it promotes compassion, selflessness and generosity, and others arguing that it leads to intolerance, isolation and even violence.
New research conducted at York University, published in the Journal of Personality and Social Psychology, may shed some light on religion's actual influence on believers – and the news is positive.
For those most severely affected, treating epilepsy means drilling through the skull deep into the brain to destroy the small area where the seizures originate – invasive, dangerous and with a long recovery period.
Do you believe in science? Your faith in science may actually make you more likely to trust information that appears scientific but really doesn't tell you much. According to a new Cornell Food and Brand Lab study, published in Public Understanding of Science, trivial elements such as graphs or formulas can lead consumers to believe products are more effective.
Our mood can affect how we walk — slump-shouldered if we're sad, bouncing along if we're happy. Now researchers have shown it works the other way too — making people imitate a happy or sad way of walking actually affects their mood.
COLUMBIA, Mo. – According to the Centers for Disease Control and Prevention (CDC), many teens skip breakfast, which increases their likelihood of overeating and eventual weight gain. Statistics show that the number of adolescents struggling with obesity, which elevates the risk for chronic health problems, has quadrupled in the past three decades. Now, MU researchers have found that eating breakfast, particularly meals rich in protein, increases young adults' levels of a brain chemical associated with feelings of reward, which may reduce food cravings and overeating later in the day.
To further study these illusive creatures, Koops set up cameras to take extensive video footage of the chimpanzees and their tool use. In doing so, she managed to capture a chimpanzee who has constructed a tool with which to investigate the camera itself - prodding it curiously and then sniffing the end of the tool (VIDEO 1).
