How does electrical stimulation modulate electrophysiological environment after SCI?

Researchers from the Chinese Academy of Sciences found that electrical stimulation with a reversed polarity can effectively modulate injury potentials and promote the spontaneous repair of cell membranes in rats with spinal cord injuries. This study proposes a method to define stimulation intensity based on injury potential values.

Considerable gender, racial and sexuality differences in attitudes toward bisexuality

A study found considerable gender, racial, and sexuality differences in attitudes toward bisexuality, with women, white people, and those identifying as lesbian or bisexual showing less bias. The research highlights the need for social marketing interventions to reduce stigma and improve HIV prevention rates within the bisexual community

VC predicts the motion of the ocean

Research led by ANU Vice-Chancellor Professor Ian Young uses satellite data to track wave decay and develop a mathematical formula for predicting swell action. The study provides comprehensive data on the rate of decay, which will increase the accuracy of wave predictions for industries such as shipping and surfing.

How pigeons may smell their way home

Researchers found that pigeons can use changes in volatile organic compounds in the atmosphere to determine their direction and find their way home. By analyzing these chemical changes, pigeons can associate specific smells with particular wind directions, allowing them to navigate back to their lofts.

Pleasure and pain brain signals disrupted in fibromyalgia patients

Research suggests that fibromyalgia is associated with disrupted brain signals for reward and punishment, contributing to hyperalgesia. Fibromyalgia patients exhibit altered brain responses to pain anticipation and relief, which may explain the heightened sensitivity to pain and lack of effectiveness of pain medications.

MiR-137, a new target for post-stroke depression?

Researchers have found that miR-137 is downregulated in the brains and peripheral blood of post-stroke depression patients. Injection of a miR-137 antagonist into the brain ventricles of post-stroke depression rats improved behavioral changes, suggesting that miR-137 suppresses Grin2A protein expression through binding to its mRNA.
