Racial, ethnic differences in opioid prescribing

A study analyzing Medicare data found that racial and ethnic minority groups received fewer opioid prescriptions for new low back pain compared to white patients. This disparity persisted during the first wave of the opioid epidemic, despite growing awareness of its adverse effects.

Study explores link between earthquakes, rainfall and food insecurity in Nepal

A study by Penn State researchers found that regions exposed to both heavy earthquake shaking and abundant rainfall in Nepal are more likely to experience food insecurity. The findings suggest that climate change is exacerbating the impact of compound events, such as earthquakes and heavy rainfall, on agriculture and human health.

Following the bouncing eyeball in augmented reality

Researchers have integrated holographic optical elements to create a waveguide eye-tracking system that can track eye movements in near-infrared wavelengths. This design enables the development of more efficient and powerful augmented reality systems.

Emissions from computing and ICT could be worse than previously thought

A new study suggests that computing and ICT could be responsible for a greater share of greenhouse gas emissions than previously thought, potentially surpassing the aviation industry. The researchers argue that historical evidence shows ICT's footprint has increased despite efficiency gains.

Meat-heavy diets restricted hunter-gatherer population sizes

A new study by the ICTA-UAB establishes that populations of hunter-gatherer groups with strong seasonal dependence on meat had fewer people per square kilometer than those relying on abundant plant foods. This result is based on a complex set of calculations showing how diet composition influenced population density.

Davis Instruments Vantage Pro2 Weather Station offers research-grade local weather data for networked stations, campuses, and community observatories.

Who’s in cognitive control?

A new study published in the Journal of Cognitive Neuroscience found that differences in cognitive control are not absolute, but rather a matter of degree. The research team, led by Todd Braver, used functional MRI to examine brain activity and behavior across four tasks in three conditions. Consistency was found in brain regions and b...

New method reveals minimum heat for Leidenfrost effect

Physicists developed an electrical technique to study the Leidenfrost effect, revealing the temperature at which vapor layers form and collapse. The results show that stable vapor layers can be sustained at 240 degrees Celsius, with a minimum heat of 140 degrees Celsius required for their existence.
