Old and young brains rely on different systems to remember emotional content

A study by Duke University Medical Center found that older adults use their brains differently when it comes to storing memories associated with negative emotions. Older adults have less connectivity between emotion-generating and memory regions, but stronger connections with the frontal cortex, which controls lower-order brain functions.

A low dose of caffeine when pregnant may damage the heart of offspring for a lifetime

A study published in the FASEB Journal found that even a low dose of caffeine ingested during pregnancy can affect fetal heart development and lead to decreased cardiac function and increased body fat in males. Researchers exposed pregnant mice to varying levels of caffeine, resulting in adverse effects on the offspring's health.

Indiana University researchers revisit male bisexuality

A recent study revisits the seven-point Heterosexual-Homosexual Rating Scale and its implications for understanding male bisexuality. The researchers argue that current studies often neglect culture's role in shaping sexual behavior, instead relying on a medical model. For future research, they suggest moving away from this lens, impro...

Just a little squeeze lets proteins assess DNA

A team of researchers from the University of Arizona has discovered a new method for protein-DNA interaction, where proteins can identify specific sequences on DNA using indirect readout. This breakthrough has implications for the development of designer drugs and could lead to a better understanding of diseases.
