Comprehensive guidelines needed for young adult preventive care

A new study from UCSF identifies a broad number of evidence-based recommendations for young adult preventive care. The transition to young adulthood is associated with increased engagement in health-damaging behaviors and preventable health problems. Primary care visits present an opportunity to improve the health of this population.

Tips from the journal mBio

A new study in mBio reveals that microbes thriving on hot fluid methane and sulfur are replaced by those feeding on solid iron and sulfur when deep-sea vents go dormant. Researchers also explore genomic sequencing data to aid rapid detection of hospital-acquired infections caused by enterococci bacteria.

Go-getters fall short in health, mortality new study shows

A new study by Timothy Judge reveals that ambitious people, who typically attend the best colleges and universities, have prestigious careers, and earn high salaries, do not necessarily lead happier or healthier lives. The research tracks 717 high-ability individuals over seven decades and finds a slightly negative impact on longevity.

New potential target for rheumatoid arthritis

Researchers have found a new potential target for rheumatoid arthritis by developing an agent that prevents activated T cells from migrating towards the site of inflammation. The agent, PS372424, binds to a specific receptor CXCR3 on activated T cells and 'blinds' them, preventing further damage.

Personality change key to improving well-being

A recent study published in Social Indicators Research found that small positive personality changes can lead to greater increases in happiness than earning more money, marrying, or gaining employment. Personality changes are strongly related to changes in well-being and contribute more to improvements in personal wellbeing.

Study finds intrauterine exposure to drugs does not affect academic achievement test scores

Researchers found no association between intrauterine cocaine or marijuana exposure and lower academic achievement scores. However, children exposed to low levels of alcohol showed decreased scores in math reasoning and spelling, even after controlling for other factors. These findings suggest that children with histories of low-level ...

Persistent depression linked with cognitive decline in older patients with coronary artery disease

A study published in Archives of General Psychiatry found that persistent depression symptoms may be associated with significant declines in cognitive performance in older patients with coronary artery disease who underwent cardiac catheterization. Patients with persistent depressive symptoms exhibited greater decline in attention/exec...

Stinging came before seeing

Researchers discovered a simple nervous system linking stinging cells and light-detecting nerve cells in Hydra magnipapillata, suggesting that light-sensing capabilities predated eye evolution. The study found that Hydras fire their stingers less in bright than in dim light, indicating the presence of light-sensitive neurons.

Making memories: How 1 protein does it

Researchers found that BDNF uses microRNA to target the production of specific proteins involved in learning and memory, and that increasing these microRNAs can halt protein production. The study sheds light on how memories are made and offers hope for treating mental disorders and neurodegenerative diseases.
