Dating violence in adolescence not only takes a physical and emotional toll on young women, it also leads to less education and lower earnings later in life, according to a first-of-its-kind study led by a Michigan State University researcher.
A young woman’s educational performance may be hindered by her partner’s actions, such as destroying books or homework or causing injuries that prevent her from going to school. (more…)
For Other Behaviors, People Care Less about Meeting Norms
COLUMBUS, Ohio – People will lie about their sexual behavior to match cultural expectations about how men or women should act – even though they wouldn’t distort other gender-related behaviors, new research suggests.
The study found that men were willing to admit that they sometimes engaged in behaviors seen by college students as more appropriate for women, such as writing poetry. The same was true for women, who didn’t hide the fact that they told obscene jokes, or sometimes participated in other “male-type” deeds. (more…)
Bethesda, MD — Dinosaurs are often thought of as large, fierce animals, but new research highlights a previously overlooked diversity of small dinosaurs. In the Journal of Vertebrate Paleontology, a team of paleontologists from the University of Toronto, Royal Ontario Museum, Cleveland Museum of Natural History and University of Calgary have described a new dinosaur, the smallest plant-eating dinosaur species known from Canada. Albertadromeus syntarsus was identified from a partial hind leg, and other skeletal elements, that indicate it was a speedy runner. Approximately 1.6 m (5 ft) long, it weighed about 16 kg (30 lbs), comparable to a large turkey.
Albertadromeus lived in what is now southern Alberta in the Late Cretaceous, about 77 million years ago. Albertadromeus syntarsus means “Alberta runner with fused foot bones”. Unlike its much larger ornithopod cousins, the duckbilled dinosaurs, its two fused lower leg bones would have made it a fast, agile two-legged runner. This animal is the smallest known plant-eating dinosaur in its ecosystem, and researchers hypothesize that it used its speed to avoid predation by the many species of meat-eating dinosaurs that lived at the same time.

A new study in the journal Neuron suggests that the brain uses a different region than neuroscientists had thought to associate objects and locations in the space around an individual. Knowing where this fundamental process occurs could help treat disease and brain injury as well as inform basic understanding of how the brain supports memory and guides behavior.
PROVIDENCE, R.I. [Brown University] — Where are you?
Conventional wisdom in brain research says that you just used your hippocampus to answer that question, but that might not be the whole story. The context of place depends on not just how you got there, but also the things you see around you. A new study in Neuron provides evidence that a different part of the brain is important for understanding where you are based on the spatial layout of the objects in that place. The finding, in rats, has a direct analogy to primate neuroanatomy. (more…)
EAST LANSING, Mich. — A few minutes of exercise can help children with attention deficit hyperactivity disorder perform better academically, according to a new study led by a Michigan State University researcher.
The study, published in the current issue of the Journal of Pediatrics, shows for the first time that kids with ADHD can better drown out distractions and focus on a task after a single bout of exercise. Scientists say such “inhibitory control” is the main challenge faced by people with the disorder. (more…)
EAST LANSING, Mich. — Most of America’s urban cores were designed for walking but offer little in the way of supermarkets, healthy restaurants and other amenities for residents to walk to, according to a study led by a Michigan State University scholar.
The study is one of the first to show that poor residents living in declining urban neighborhoods want healthy food choices – evidenced by their willingness to travel long distances to find them. Past research has generally assumed that poor people will shop at whatever store is closest. (more…)
UCLA study quantifies learning curve for robotic-assisted surgery
Prostate cancer is the most commonly diagnosed non-skin cancer in the U.S., and radical prostatectomy, the surgical removal of the prostate gland, remains the most popular therapeutic option, accounting for half of treatments.
The procedure, however, is not without possible side effects, primarily erectile dysfunction and incontinence. But a good nerve-sparing surgical technique can lessen the likelihood of these undesirable outcomes, as can the skill and experience of the surgeon, according to a new UCLA study that focused on robotic-assisted prostate surgery.
The study findings are published in the June 2012 print edition of the international peer-reviewed journal European Urology. (more…)
We hold many beliefs about memory—for instance, if you study more, you learn more. We are also constantly making judgments about particular instances of learning and remembering—I’ll never forget this party! That was easy to understand. I’ll ace it on the test.
But do beliefs influence judgments, and how do judgments affect memory performance? “There’s a disconnect among beliefs, judgments, and actual memory,” says Williams College psychologist Nate Kornell. Ask people to predict how or what they will learn and “in many situations, they do a breathtakingly bad job.” (more…)
