EVANSTON, Ill. --- A combination of fiscal constraints and improvements in technology has led to an increased reliance on online classes of all types -- many of which use Internet versions of traditional, live lectures. Now a new study released by the National Bureau of Economic Research (NBER) raises questions about that fast-growing trend in higher education.

The cause of diabetes during pregnancy is directly controlled by serotonin, a chemical produced by the body and normally known as a neurotransmitter, and is influenced by the amount of protein in the mother's diet early in pregnancy, according to new findings of an international team led by researchers at UCSF.
Two actors wrapped in motion sensors circle each other, as engineering researchers stand at the perimeter of a USC Viterbi School of Engineering laboratory, taking note.
It's an unusual partnership between artists and engineers, and a union the National Science Foundation (NSF) expects will achieve more precise methods of modeling human behavior.
SALT LAKE CITY – Using an experimental mouse model for malaria, an international group of scientists has discovered that adding antioxidant therapy to traditional antimalarial treatment may prevent long-lasting cognitive impairment in cerebral malaria. Their findings were published online June 24, 2010, in the journal PLoS Pathogens.
WEST LAFAYETTE, Ind. - Part of what makes those relationships so golden during the golden years is that people of all ages are more likely to forgive and respect one's elders, according to research from Purdue University.
At a time when consumer interest in health-enhancing foods is high, Agricultural Research Service (ARS)-funded scientists have contributed to a limited but growing body of evidence of a link between vitamin D and cognitive function.
LOS ANGELES (June 24, 2010) – The nerve cell-damaging plaque that builds up in the brain with Alzheimer's disease also builds up in the retinas of the eyes – and it shows up there earlier, leading to the prospect that noninvasive optical imaging of the eyes could lead to earlier diagnosis, intervention and monitoring of the disease, according to new research.
COLLEGE STATION, June 24, 2010 — Caring for a child with a disability can be challenging, but many of these challenges are due to a lack of necessary environmental supports, according to a study conducted by researchers at the Texas A&M University Center on Disability and Development.
Results of the study, a part of a larger statewide needs assessment for families that have children with disabilities, is published in the current issue of Rehabilitation Psychology.
A trial of a novel radioactive compound readily and safely distinguished the brains of Alzheimer's disease patients from healthy volunteers on brain scans and opens the doors to making such imaging available beyond facilities that can manufacture their own radioactive compounds. The results, reported by a Johns Hopkins team in the June Journal of Nuclear Medicine, could lead to better ways to distinguish Alzheimer's from other types of dementia, track disease progression and develop new therapeutics to fight the memory-ravaging disease.
HOUSTON, June 24, 2010 – Many diseases of brain function, such as epilepsy and schizophrenia, are caused by problems in how neurons communicate with each other. A University of Houston (UH) researcher and his team are analyzing these commands and connections in an attempt to prevent those diseases.
CAMBRIDGE, Mass. -- Psychologists report this week in the journal Science that interpersonal interactions can be shaped, profoundly yet unconsciously, by the physical attributes of incidental objects: Resumes reviewed on a heavy clipboard are judged to be more substantive, while a negotiator seated in a soft chair is less likely to drive a hard bargain.
Why is it that only some drug users become addicts? This is the question that has been addressed by the teams of Pier Vincenzo Piazza and Olivier Manzoni, at the Neurocentre Magendie in Bordeaux (Inserm unit 862). These researchers have just discovered that the transition to addiction could result from a persistent impairment of synaptic plasticity in a key structure of the brain. This is the first demonstration that a correlation exists between synaptic plasticity and the transition to addiction.
NEW YORK (June 24, 2010) – A team of researchers led by NewYork-Presbyterian Hospital/Columbia University Medical Center has developed a method to predict post-stroke recovery of language by measuring the initial severity of impairment. Being able to predict recovery has important implications for stroke survivors and their families, as they plan for short and long-term treatment needs. Findings are reported online in the journal Stroke.

DENVER—Head injury expert Kim Gorgens, a neuropsychologist at the University of Denver (DU), says that most concussions deliver a G-force equivalent to 95 upon impact. By comparison, the average G-force experienced by military fighter pilots is 9. G-force is a unit of force equal to the force exerted by gravity. Gorgens says the average football player receives 103 G's when hit during a game.
