Researchers explain how the brain integrates head position and acoustics

Researchers discovered that fusiform cells in the cochlear nucleus integrate acoustic information with head and ear position information to pinpoint sound sources. The study found that synapses transmitting acoustic information are stable, while those carrying head and ear position information exhibit plasticity.

Patients' lives at risk from needless lung scans

A recent study found that injecting contrast material before a CT scan can increase lung tissue volume in critically ill patients with ALI. This increase is attributed to fluid accumulation in the lungs, making breathing harder for these patients. The authors recommend avoiding this procedure in critically ill patients.

Serotonergic dysfunction doesn’t cause suicide

Researchers found no significant differences in TPH protein level or 5HT2A receptor density between suicide victims and controls. The A218C polymorphism of the TPH gene was shown to alter TPH protein level, suggesting its role in serotonergic function rather than biological suicidality.

Drinks of the father

Researchers found that a father's maximum number of drinks consumed in 24 hours is associated with disruptive behavior disorders, early substance-use initiation, and early substance-related disorders in his children. The study suggests that this 'phenotype' could supplement diagnostic categories for alcohol dependence.

Study suggests inflammatory protein is strongly associated with heart disease

A new study suggests that high levels of inflammatory protein CRP are strongly associated with an increased risk of ischemic heart disease. The research found that patients taking beta blockers and statins had less inflammation, indicating that treating inflammation may play a crucial role in preventing heart disease.

Designing a robot that can sense human emotion

Researchers at Vanderbilt University are developing a robot that can detect and respond to human emotions. They use physiological signals such as heart rate, skin conductance, and facial muscle activity to analyze a person's psychological state. The robot is programmed to recognize specific patterns and provide supportive responses.

Researcher debates changing attitudes of Americans: historical, generational, or aging?

A researcher challenges the idea that generations drive attitude changes in America, arguing instead that individual life experiences, aging, and historical events play a significant role. Alwin's study suggests that social change is more complex than previously thought, with multiple factors contributing to generational differences.
