Benchmarking theory with experiments for oxygen reduction catalysts

Tohoku University researchers created a reliable means of predicting the performance of molecular metal-nitrogen-carbon (M-N-C) catalysts. Their breakthrough uses pH-field coupled microkinetic modeling to evaluate charge transfer at the Fe-site, identifying suitable surrounding functional groups for oxygen reduction reactions.

Genetic testing of patients with atrial fibrillation can alert clinicians to potential development of life-threatening conditions

A recent White Paper published in the Canadian Journal of Cardiology analyzes the current understanding of genetics in atrial fibrillation and recommends screening for genetic heart disease in early onset AF cases. This may lead to identification of life-threatening ventricular cardiomyopathy and channelopathy syndromes, highlighting t...

New study shows association of historical housing discrimination and shortfalls in colon cancer treatment

A nationwide study finds that individuals diagnosed with colon cancer who resided in previously redlined neighborhoods are more likely to be diagnosed with advanced-stage disease and have worse survival rates. The research highlights the long-lasting impact of institutional racism on access to quality cancer care.

The language spoken by others conditions our ability to predict their actions from an very early age, according to a study by UPF

A study by UPF found that six-month-old babies can predict the actions of people who speak their native language, but not those who speak an unfamiliar language. This suggests that infants' ability to predict others' behavior is linked to the language they speak and may be influenced by social factors.

Lyrebird synchronizes elements of its mating dance

Researchers found that Albert's Lyrebirds synchronize their footwork with the beat of their song and manipulate the environment by shaking thorny vines to create a choreographed courtship display. This behavior is thought to enhance the male's display, making him appear bigger and more vigorous.

When inequality is more than “skin-deep”: Social status leaves traces in the epigenome of spotted hyenas in Tanzania

Researchers found that social status is reflected in epigenetic signatures, including DNA methylation patterns, in juvenile and adult free-ranging spotted hyenas. These patterns are linked to important physiological processes such as energy conversion and immune response.
