Untangling quantum entanglement with new calculation formulas

Osaka Metropolitan University
Peer-Reviewed Publication

Physicists developed simplified formulas to quantify quantum entanglement in strongly correlated electron systems. Their approach was applied to nanoscale materials, revealing unexpected quantum behaviors and identifying key quantities for the Kondo effect. These findings advance understanding of quantum technologies.

Socioeconomic factors fuel global inequalities in Alzheimer's disease burden, study finds

Elsevier
Peer-Reviewed Publication

An analysis of the global burden and temporal trends of Alzheimer's disease and other dementias (ADODs) reveals significant cross-country inequalities associated with a series of sociodemographic development-related risk factors, such as education, income, fertility, and health expenditure. The new study in the American Journal of Preventive Medicine, published by Elsevier, calls for the development of targeted prevention and control strategies in different countries.

Foraging footballers suggest how we come together to act as one

Okinawa Institute of Science and Technology (OIST) Graduate University
Peer-Reviewed Publication

Originally described in the context of particles drifting through liquid, Lévy walk has been found to accurately describe a very wide range of phenomena, from cold atom dynamics to swarming bacteria. And now, a new study published in Complexity has for the first time found Lévy walk in the movements of competing groups of organisms: football teams.

New research explores how AI can build trust in knowledge work

Carnegie Mellon University
Peer-Reviewed Publication

In a new study, researchers explored how artificial intelligence (AI) can enhance performance and trust in knowledge work environments. They found that when AI systems provided feedback in real-time, performance and trust increased.

WVU researchers find babies born to teen mothers are smaller, weigh less

West Virginia University
Peer-Reviewed Publication

At a time when the number of teens having babies in the Mountain State remains higher than the national average, maternal and child health researchers at West Virginia University found these infants have lower birth weights and are smaller for their gestational ages compared with those born to adults.

With $2M in grants, Arizona engineers push toward a quantum computing future

University of Arizona College of Engineering
Grant and Award Announcement

Adoption of quantum technologies has been stymied by factor, including high error rates. These mistakes occur because quantum systems are highly sensitive to external disturbances like temperature and sound. Effective error correction would protect high-performance data processing, but this area of research has had limited exploration, until now.

Is red wine a healthier choice than white wine? Uncorking the cancer risks

Brown University
Peer-Reviewed Publication

Researchers from the Brown University School of Public Health have conducted a study that scours “the vast and often contradictory literature on the carcinogenicity of red and white wine” to assess whether this assumption holds up, and to compare the cancer risks associated with wine type.
