Musical experience offsets some aging effects

A Northwestern University study finds that lifelong musical training can benefit adults by offsetting age-related decline in memory and ability to hear speech in noisy environments. Musicians aged 45-65 outperform non-musicians in auditory memory, hearing speech in noise, and other cognitive functions.

Blame the 'chaperone'

A Jackson Laboratory research team has identified a mutation in a gene essential for correct protein-processing, which disrupts cellular development and growth. The study found that defects in the chaperone proteins lead to photoreceptor degeneration, central nervous system abnormalities, and male infertility.

CSHL scientists show in unprecedented detail how cortical nerve cells form synapses with neighbors

Researchers at Cold Spring Harbor Laboratory have made a breakthrough in understanding how neural circuits self-assemble. By observing the formation of inhibitory synapses, they found that GABA transmission regulates synaptic adhesion. The discovery sheds light on neurodevelopmental disorders such as autism and schizophrenia.

Tetris flashback reduction effect 'not common to all games'

A study found that playing Tetris after viewing traumatic images reduced memory flashbacks in healthy volunteers. However, playing a word-based quiz game increased flashbacks. The researchers suggest that Tetris competes with the brain's perceptual information channel, reducing traumatic memories.

BPA and testosterone levels

A large population study found a statistically significant association between BPA exposure and increased testosterone levels in men. The study, which analyzed data from over 700 adults aged 20-74 years, suggests that even low-level exposure to BPA may have endocrine-disrupting effects on human health.
