Researchers have found that induced pluripotent stem cell--derived cardiomyocytes from a patient with arrhythmogenic cardiomyopathy recapitulate the reduced contractility and impaired desmosome assembly associated with this disease, providing a rapid and convenient platform for developing new treatments such as gene replacement therapy.

Social media use has been linked to biological and psychological indicators associated with poor physical health among college students, according to new results. Research participants who used social media excessively were found to have higher levels of C-reactive protein (CRP), a biological marker of chronic inflammation that predicts serious illnesses, such as diabetes, certain cancers and cardiovascular disease. In addition to elevated CRP levels, results suggest higher social media use was also related to somatic symptoms, like headaches, chest and back pains, and more frequent visits to doctors and health centers for the treatment of illness.

Researchers have identified the highly prevalent, specific mutations that are causing the Omicron variant's high rate of infection. The findings help explain how the new variant can escape pre-existing antibodies present in the human body, either from vaccination or naturally from a recent COVID-19 infection.

To understand the dynamics of emerging topics in science and medicine, researchers looked at researcher participation in articles containing emerging keywords over 50 years. They found that although more human resources are needed for publication, large research groups less frequently generate emerging topics. Moreover, expertise in certain topics has become important for generating emerging topics, and researchers who generate emerging topics now tend to remain in that field.
