Athens, Ga. – New research from the University of Georgia has identified the neural pathways in an insect brain tied to eating for pleasure, a discovery that sheds light on mirror impulsive eating pathways in the human brain.

TORONTO, Feb. 28, 2013— Most serious traffic accidents occur when drivers are making a left-hand turn at a busy intersection.

When those drivers are also talking on a hands-free cell phone, "that could be the most dangerous thing they ever do on the road," said Dr. Tom Schweizer, a researcher at St. Michael's Hospital.

New Rochelle, NY, February 28, 2013—Sexting, the use of technology to send or receive sexually explicit messages, photos, or videos, is a relatively new trend and, in many cases, has legal implications. As many as 25-50% of young people may participate in sexting.

Tel Aviv — In addition to struggling in school, many learning disabled children are known to face social and emotional challenges including depression, anxiety, and isolation. Often beginning early in childhood, they become more pronounced during adolescence, an emotionally turbulent time.

It could be a grotto. Light is glowing up from below and gives the moving waves a glance of an opal under the sunlight. "This computer graphic was written with our new description language by a schoolboy in not more than two hours after a briefly reading of the instructions", explains Felix Klein, doctoral candidate at the chair of Computer Graphics at Saarland University. As Klein is moving three slide switches with the mouse which are placed under the wave graphic on the display, the water is transforming.

Having more control in the workplace can have negative consequences for individuals but it depends on the form of job control, according to new research out of the University of Toronto.

Bethesda, MD—Here's another reason why a healthy diet during pregnancy is critical to the future health of your children: New research published in the March 2013 issue of The FASEB Journal, suggests that pregnant mothers who consume junk food actually cause changes in the development of the opioid signaling pathway in the brains of their unborn children. This change results in the babies being less sensitive to opioids, which are released upon consumption of foods that are high in fat and sugar.

PROVIDENCE, R.I. [Brown University] — A team of neuroengineers based at Brown University has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects. Several copies of the novel low-power device, described in the Journal of Neural Engineering, have been performing well in animal models for more than year, a first in the brain-computer interface field. Brain-computer interfaces coud help people with severe paralysis control devces with their thoughts.

DURHAM, N.C. -- Researchers have electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles. A further test of this work successfully linked the brains of two animals thousands of miles apart—one in Durham, N.C., and one in Natal, Brazil.

A new analysis has found that a combination of methods that help patients with dementia remember proper eating habits can improve their physical health and lessen symptoms of depression. Published early online in the Journal of Advanced Nursing, the study indicates that clinicians should consider using this intervention in individuals with dementia who also have poor nutrition and signs of depression.

MEDFORD/SOMERVILLE, Mass. (February 27, 2013) – For the first time, scientists have shown that transplanted eyes located far outside the head in a vertebrate animal model can confer vision without a direct neural connection to the brain.

Biologists at Tufts University School of Arts and Sciences used a frog model to shed new light – literally – on one of the major questions in regenerative medicine, bioengineering, and sensory augmentation research.

ROCHESTER, Minn. — Researchers have identified a possible treatment window of several years for plaques in the brain that are thought to cause memory loss in diseases such as Alzheimer's. The Mayo Clinic study is published in the Feb. 27 online issue of Neurology, the medical journal of the American Academy of Neurology.

Children who failed to acquire a basic math skill in first grade scored far behind their peers by seventh grade on a test of the mathematical abilities needed to function in adult life, according to researchers supported by the National Institutes of Health.

As a bird sings, some neurons in its brain prepare to make the next sounds while others are synchronized with the current notes—a coordination of physical actions and brain activity that is needed to produce complex movements, new research at the University of Chicago shows.

In an article in the current issue of Nature, neuroscientist Daniel Margoliash and colleagues show, for the first time, how the brain is organized to govern skilled performance—a finding that may lead to new ways of understanding human speech production.

EVANSTON, Ill. --- Trust fools you into remembering that your partner was more considerate and less hurtful than he or she actually was.

New research from Northwestern University and Redeemer University College (Ontario, Canada) is the first to systematically examine the role of trust in biasing memories of transgressions in romantic partnerships.
