CAMBRIDGE, MA -- "The sounds uttered by birds offer in several respects the nearest analogy to language," Charles Darwin wrote in "The Descent of Man" (1871), while contemplating how humans learned to speak. Language, he speculated, might have had its origins in singing, which "might have given rise to words expressive of various complex emotions."

WACO, Texas (Feb. 20, 2013) —Obesity, diabetes and other ailments plague impoverished communities at higher rates than the general United States population. In rural Texas border towns, or colonias, Mexican-American residents are at an even greater risk for chronic health problems.
Philadelphia, PA, February 21, 2013 – A new study published in the March issue of The American Journal of Pathology suggests that cortical type 2 cannabinoid (CB2) receptors might serve as potential therapeutic targets for cerebral ischemia.
In many animals, the brain is located in a specific structure, the head, together with sensory organs and often together with the mouth. However, there are even more distantly related animals, which have a nervous system, but no brain, like sea anemones and corals.
EAST LANSING, Mich. — A memo to employers: Just because your workers live alone doesn't mean they don't have lives beyond the office.
New research at Michigan State University suggests the growing number of workers who are single and without children have trouble finding the time or energy to participate in non-work interests, just like those with spouses and kids.
Workers struggling with work-life balance reported less satisfaction with their lives and jobs and more signs of anxiety and depression.
It's not unusual for cancer patients being treated with chemotherapy to complain about not being able to think clearly, connect thoughts or concentrate on daily tasks. The complaint – often referred to as chemo-brain – is common. The scientific cause, however, has been difficult to pinpoint.
WASHINGTON - Feeling good about spending money on someone else rather than for personal benefit may be a universal response among people in both impoverished countries and rich nations, according to new research published by the American Psychological Association.
"Our findings suggest that the psychological reward experienced from helping others may be deeply ingrained in human nature, emerging in diverse cultural and economic contexts," said lead author Lara Aknin, PhD, of Simon Fraser University in Canada.
People who are at greater genetic risk of schizophrenia are more likely to see a fall in IQ as they age, even if they do not develop the condition.
Scientists at the University ofEdinburgh say the findings could lead to new research into how different genes for schizophrenia affect brain function over time. They also show that genes associated with schizophrenia influence people in other important ways besides causing the illness itself.
The researchers used the latest genetic analysis techniques to reach their conclusion on how thinking skills change with age.
The drug scopolamine has been used to treat a variety of conditions, including nausea and motion sickness. A new study by UCLA life scientists suggests that it may also be useful in treating anxiety disorders.
In the weeks, months and years after a severe head injury, patients often experience epileptic seizures that are difficult to control. A new study in rats suggests that gently cooling the brain after injury may prevent these seizures.
Scientists from the University of Southampton have identified the molecular system that contributes to the harmful inflammatory reaction in the brain during neurodegenerative diseases.
An important aspect of chronic neurodegenerative diseases, such as Alzheimer's, Parkinson's, Huntington's or prion disease, is the generation of an innate inflammatory reaction within the brain.
New Orleans, LA – Research conducted by a team of scientists from Columbia University College of Physicians and Surgeons and Dr. Nicolas Bazan, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans, found the novel use of a component of fish oil reduced brain trauma in newborn mice. The study reports that neonatal brain damage decreased by about 50% when a triglyceride lipid emulsion containing docosahexaenoic acid (DHA) was injected within two hours of the onset of ischemic stroke.
New York, NY (February 20, 2013) — Triglyceride lipid emulsions rich in an omega-3 fatty acid injected within a few hours of an ischemic stroke can decrease the amount of damaged brain tissue by 50 percent or more in mice, reports a new study by researchers at Columbia University Medical Center.
The results suggest that the emulsions may be able to reduce some of the long-term neurological and behavioral problems seen in human survivors of neonatal stroke and possibly of adult stroke, as well. The findings were published today in the journal PLoS One.
MINNEAPOLIS – Contrary to other research, a new study found that the total level of antioxidants in people's diets is not related to their risk of developing stroke or dementia. The study is published in the February 20, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. Antioxidants such as lycopene, beta-carotene and vitamins C and E are found in many foods.
DURHAM, NC – Bullied children grow into adults who are at increased risk of developing anxiety disorders, depression and suicidal thoughts, according to a study led by researchers at Duke Medicine.
The findings, based on more than 20 years of data from a large group of participants initially enrolled as adolescents, are the most definitive to date in establishing the long-term psychological effects of bullying.
