Language patterns and gene expression

Researchers analyzed audio clips from 143 adults to find individual language patterns related to gene expression and adversity; they discovered that these patterns better predicted adverse gene profiles than self-reported measures of anxiety and stress. This study provides a new link between spoken language and immune system regulation.

Cool idea: Magma held in 'cold storage' before giant volcano eruption

A team of researchers has found that the magma body at Long Valley was much cooler before the eruption than previously thought. The discovery challenges the traditional view of a long period with a big tank of molten rock in the crust, instead suggesting that magma is stored for a short period in a cool, crystalline state.

Crime-scene technique used to track turtles

Green turtles breed in Cyprus and forage in Lake Bardawil, a new important feeding ground discovered using stable isotope ratios and satellite tracking. The study found that 82% of female turtles show high consistency in their isotope ratios, indicating they return to the same places.

Breaking cell symmetry

Researchers discover that cortical tension plays a key role in clustering proteins and establishing cell polarity. This force-driven mechanism allows cells to establish polarity without wasting energy by actively transporting proteins or cellular components.

Dental filling failure linked to smoking, drinking and genetics

A new study published in Frontiers in Medicine found that patients who drink alcohol or smoke are more likely to experience dental filling failure. Genetic differences were also discovered to be associated with increased filling failure rates, suggesting personalized treatments could lead to improved outcomes.

Study: Lupus patients endorse PROMIS assessment tool as relevant, valuable and potentially useful in improving clinical care

PROMIS is a patient-reported outcomes measurement system that evaluates physical, psychological, and social well-being to provide information on the subjective patient experience. Lupus patients endorse PROMIS assessments as reflecting their experience with lupus, highlighting its potential utility in validating symptoms, tracking dise...

Afterschool program environments linked to academic confidence and skills

A new study by NYU Steinhardt School of Culture, Education, and Human Development found that afterschool programs with positive, responsive, and organized environments can have significant academic benefits for students. The study examined the role of afterschool classroom environment in terms of academic outcomes for youth with and wi...

A quasiparticle quest

Researchers have developed a device using graphene that could provide conclusive evidence for the existence of non-Abelian anyons, a key component of topological quantum computing. The device achieves extremely low disorder and tunability, allowing for the study of these particles in a controlled environment.

Controlling nerve injury repair revealed in Monash University study

Researchers found signals in a tiny worm that control the mechanism of severed nerves self-healing. The discovery enables genetic control over this process, raising hopes for treating nerve injuries in humans. The study used laser beams to sever neurons and observed how they regenerated, finding full function restored within 48 hours.

Microfinance institutions are found effective in giving health products to underserved communities

A new study by The Arnhold Institute for Global Health found that microfinance institutions can effectively distribute essential health products to rural communities, leading to improved child health outcomes. Microfinance networks were used to deliver micronutrient supplements, resulting in a significant impact on the health of childr...

Brighter flexible electroluminescent film by adopting eye structure of nocturnal animals

A research team at DGIST has developed an electroluminescent film that is four times brighter than existing ones, using the retro-reflection principle of nocturnal animal eyes. The film can fabricate high luminance electroluminescent light sources by controlling luminescent particle concentrations.

More physical activity and higher intensity physical activity may significantly reduce risk of death in older women in the short term

A new study found that more moderate to vigorous-intensity physical activity significantly reduces the risk of death among older women, but light intensity activity or sedentary behavior had no independent association. The research suggests that even low-level activities can have health benefits for other outcomes.
