Dominant Persons Set Cardiovascular Rates Surging

Researchers found that dominant men and women exhibit high cardiovascular reactivity when interacting with others, responding to gender norms. In mixed-gender situations, dominant women deactive their traits, while dominant men respond to male gender role norms.

Heavy Traffic At The Nuclear Pore: How Proteins And RNA Leave The Cell Nucleus

The nuclear pore complex is a highly regulated structure composed of around 50-100 different proteins that control the transport of macromolecules between the nucleus and cytoplasm. Ran protein plays a crucial role in this process, binding selectively to transport factors to regulate cargo molecules across the nuclear pore.

1998 Was Warmest Year Of Millenium, Climate Researchers Report

Researchers found that the 20th century warming counters a 1,000-year-long cooling trend and reversed a medieval warming period. Temperatures in the latter half of the 20th century were unprecedented, with human-induced greenhouse gases being a major factor.

Control That Computer With A Wave Of Your Hand

MIT researchers have created a sensory tabletop that can track hand movements in three dimensions, allowing for new interactive technologies. The table uses electrodes to detect tiny currents generated by the user's hand, which are then used to calculate the hand's position in 3D space.

Breakthrough? Study Finds Dopamine Cannot Be Source Of Pleasure In Brain

A University of North Carolina at Chapel Hill study reveals that dopamine plays an early central role in pleasure but another chemical like serotonin is actually responsible for the sensation. Researchers believe this discovery could lead to better explanations for substance abuse and addiction, as well as new treatments.

Genetic Mutations Linked To Rare Metabolic Disease

Researchers have identified two genetic mutations as the cause of megaloblastic anemia 1, a rare disease affecting vitamin B-12 absorption. The disease is exceedingly rare, occurring in only one person in a million, but can be fatal if left untreated.

Transmitters May Give Off-Piste Skiers A False Sense Of Security

Recent studies indicate that electronic transmitters used by off-piste skiers to locate buried victims are ineffective due to limited range and prolonged rescue times. The signals only carry up to 50 meters and professional skiers take an average of 18 minutes to reach their companions, resulting in a low survival rate.
