Macular Degeneration :: USC biomedical team to participate in $6 million low vision project

An interdisciplinary team of biomedical researchers from the USC Viterbi School, the College and the Keck School of Medicine of USC has received a $6-million Bioengineering Research Partnership grant from the National Institutes of Health (NIH) to begin designing visual aids for millions of older adults who suffer from significant vision loss.

Psychology :: How emotionally charged events leave their mark on memory

Researchers have uncovered new evidence in mice that may explain how emotionally charged situations can leave such a powerful mark on our memories. Surges of the stress hormone norepinephrine (also known as noradrenaline) that often accompany strong emotions spark a series of molecular events that ultimately strengthen the connections between neurons, the team reports in the Oct. 5, 2007, issue of the journal Cell, a publication of Cell Press.

Psychology :: What emotional memories are made of

Both extensive psychological research and personal experiences confirm that events that happen during heightened states of emotion such as fear, anger and joy are far more memorable than less dramatic occurrences. In a report this week in Cell, Johns Hopkins researchers and their collaborators at Cold Spring Harbor and New York University have identified the likely biological basis for this: a hormone released during emotional arousal “primes” nerve cells to remember events by increasing their chemical sensitivity at sites where nerves rewire to form new memory circuits.

Psychology :: Can thinking about shopping change the route you take?

Prior research has shown that exposure to business-related objects makes people act more competitively, even though they do not realize it. A fascinating new study by researchers at Stanford extends this research by investigating how different consumers are affected by the same stimuli. The study reveals significant differences between the way men and women subconsciously react after exposure to certain objects.

Psychology :: ACOG Supports Domestic Violence Awareness Month

During Domestic Violence Awareness Month in October, The American College of Obstetricians and Gynecologists (ACOG) calls attention to the 2 million women in the US who are physically or sexually assaulted by an intimate partner each year. Domestic, or intimate partner, violence is an ongoing public health problem that accounts for 22% of all violent crimes against women.

Gene :: Genes may hold the keys to how humans learn

New research is giving scientists fresh insights into how genetics are a prime factor in how we learn. Michael Frank, an assistant professor of psychology and director of the Laboratory for Neural Computation and Cognition at The University of Arizona, headed a team whose results are reported in the Oct. 1 issue of Early Edition, an online site hosted by the Proceedings of the National Academy of Sciences.

Heart Disease :: Depression, aging, and proteins made by a virus may all play role in heart disease

Researchers here have linked an increase in two immune system proteins essential for inflammation to a latent viral infection and proposed a chain of events that might accelerate cardiovascular disease. The same process may be involved in a host of other ailments plaguing the elderly.
