The hemispheres are not equal: How the brain is not symmetrical

Research found that human brain hemispheres have distinct functional patterns, with regions on the left and right sides specialized for different tasks. Individual differences in these arrangements were heritable, suggesting genetic influence, while environmental factors also play a role. The study also compared humans to monkeys, find...

Electrically controlled exchange-bias effect discovered in magnetic van der Waals heterostructures

Researchers have discovered a way to electrically control the exchange bias effect in FePS3–Fe5GeTe2 van der Waals heterostructures. By introducing protons into the interface, they were able to switch the exchange bias effect on and off. The findings have significant implications for the development of spintronics devices.

NIH-funded team develops method to identify future SARS-CoV-2 mutations that could affect rapid antigen test performance

A NIH-funded team developed a method to evaluate how mutations in the SARS-CoV-2 N protein affect recognition by antibodies used in rapid antigen tests. The study found that none of the major past and present variants of concern contain N protein mutations affecting diagnostic antibody performance.

Machine learning gives glimpse of how a dog's brain represents what it sees

Researchers at Emory University used machine learning and fMRI to analyze a dog's brain activity while watching videos. The results show that dogs are more attuned to actions in their environment than to who or what is performing the action. This study offers proof of concept for decoding canine visual perception.

Hotel smoking restrictions fail to fully protect guests from thirdhand smoke

A new study by San Diego State University analyzed 332,277 TripAdvisor guest reviews and found that designated smoking and non-smoking rooms are insufficient for protecting guests from thirdhand smoke. Hotels that adopted 100% smoke-free policies had significantly fewer complaints related to tobacco pollution.

Moral values explain differences in COVID-19 vaccination rates across US counties

A study from USC Dornsife reveals that moral values, including care, fairness, loyalty, authority, and purity, predict regional differences in COVID-19 vaccination rates. Counties with residents prioritizing purity were less likely to be vaccinated, while those emphasizing loyalty and fairness had higher vaccination rates.
