LSU sociology professor researches the relationship between religion and educational attainment

A recent study by LSU sociology professor Samuel Stroope examines the relationship between religion and educational attainment in the US. The findings reveal that individual biblical literalism is negatively associated with college completion, while congregational biblical literalism has a sharp negative impact on non-literalists.

Mothers don't speak so clearly to their babies

New research published in Psychological Science suggests that mothers may speak less clearly to their infants than they do to adults. The study found that mothers tend to use cutesy words and a sing-song voice when talking to babies, but still pronounce sounds slightly less distinctly than when addressing adults.

Infrared imaging technique operates at high temperatures

Researchers at Northwestern University developed a new detector that can capture high-resolution mid-wavelength infrared images at room temperature, paving the way for applications in surveillance and disease detection. The technology has potential for vascular imaging and disease detection, particularly with images of the human body.

Warming seas decrease sea turtle basking

Researchers found that green turtles tend not to bask when local winter sea surface temperatures stay above 23 degrees Celsius. The scientists project that global warming trends could lead to the end of beach basking globally by 2102, with Hawaii's green turtles possibly stopping by 2039.

Tonal languages require humidity

Researchers found that tonal languages are more prevalent in humid climates, while simpler tone pitches dominate dry regions. The study suggests that humidity affects vocal fold elasticity and ion balance, making it easier to produce a wide range of tones.

Sisters act together

Researchers studied the dispersal behavior of female and male cichlids in Lake Tanganyika. Females dispersed significantly longer distances than males, likely to avoid inbreeding and resource competition. Kin-shoaling also emerged as a key phenomenon, with small females tending to shoal with female siblings.

New machine-perfusion organ preservation system keeps livers healthier for transplant

A new preservation system that uses machine perfusion keeps livers healthier for up to nine hours before transplantation, leading to better liver function and increased survival rates. The system has shown promising results in animal studies, with 100% of pigs surviving after receiving perfused livers.

Reducing Myc gene activity extends healthy lifespan in mice

A study at Brown University found that reducing Myc gene activity increased the healthy lifespan of laboratory mice by 15%. The mice exhibited better health and organ function, with reduced signs of aging. The study's findings offer encouragement for developing cancer drugs targeting Myc and potential benefits for human health.

Low-income boys fare worse in wealth's shadow

New research from Duke University finds that low-income boys exhibit more antisocial behavior when living among affluent neighbors, while girls do not show a similar effect. The study suggests that neighborhood surroundings play a significant role in shaping the behavior of low-income children.

These jellyfish aren't just drifters

Researchers tracked jellyfish movements with GPS loggers and observed their swimming direction to show they can actively swim counter-current in response to drift. The findings could help predict and avoid troublesome jellyfish blooms, improving management of these ocean ecosystems.

Using viruses to find the cellular Achilles heel

Two deadly viruses, hepatitis C and Kaposi's sarcoma-associated herpesvirus, were found to target common host proteins that are critical for human biology. By studying protein interactions between viruses and cells, scientists have identified potential new targets for anti-viral treatments.

Boston's leaky pipes release high levels of heat-trapping methane

A Harvard-led study reveals that up to 2.7% of the gas delivered to Boston households escapes into the atmosphere, with emissions accounting for 60-100% of regional methane release depending on the season. The findings highlight the need for innovative policymaking to address methane loss from natural gas infrastructure.
