Genetic 'usual suspects' identified in researchers' new list

Scientists at Cold Spring Harbor Laboratory have created a ranked list of genes that are likely to be involved in any disease, allowing researchers to distinguish between these 'usual suspects' and those unique to specific conditions. The study's findings provide valuable context for interpreting gene activity in disease onset.

Distracted drivers 29 times more likely to wreck in a highway work zone

Researchers at the University of Missouri found that drivers who are distracted while driving in a highway work zone are 29 times more likely to be involved in a collision or near-miss. The study analyzed data from over 3,000 drivers and provides recommendations for behavioral countermeasures to reduce injuries and fatalities.

Attitudes about health affect how older adults engage with negative health news

A study by North Carolina State University found that older adults are more willing to engage with negative health information when they have a positive attitude towards their health. Participants who completed a checklist designed to make them feel good about their lifestyle choices read more than 50% of the negative articles, compare...

A step closer to an HIV cure

Researchers have found no rebound of HIV in two patients who stopped taking their medication after receiving stem cell transplants, providing crucial insights into the potential mechanisms of cure. The transplanted donor cells had a gene defect that made it difficult for HIV to infect cells, offering new hope for developing a cure.

Matrix could ensure vital copper supplies

Researchers have identified a matrix of 12 risk categories that consider environmental, social, governance and mineralogical factors affecting the viability and accessibility of complex copper orebodies. The study found that 75% of undeveloped copper orebodies face environmental, social and governance challenges.

Looks matter when it comes to success in STEM, study shows

A Rice University study reveals that students who look more racially stereotypical are more likely to persist in STEM fields, while those who do not fit the mold face higher drop-out rates. Asian students who look more like their racial group are more likely to complete a STEM degree, but black students who do so are less likely.

Life-threatening birth complication rate increasing across US racial, ethnic groups

A recent NIH-funded analysis of California hospital records found a significant increase in severe maternal morbidity among US women from diverse racial and ethnic backgrounds. The study revealed substantial disparities in life-threatening birth complications, with non-Hispanic black women facing the highest rates.

Mom-to-mom phone calls lift breastfeeding rate

An Australian study found that regular telephone support from experienced breastfeeders increased breastfeeding rates among first-time mothers by 75%, compared to 69% in the control group. The program also improved mothers' ability to cope with challenges, leading to a significant increase in exclusive breastfeeding at six months.
