A toddler running sometimes loses footing because both feet come off the ground at the same time. Kinesin motors that move materials around in cells have the same problem, which limits how fast they can traverse a microtubule in the cell and carry cargo, according to Penn State researchers who have now seen these kinesin motors move using an unusual microscope and tagging method.
Images of the brain's gray and white matter obtained with multiple MRI techniques can help identify and track cognitive impairment in active professional fighters, according to a new study.
Educational videos delivered by text or email successfully encouraged new mothers to use safe sleep practices for their babies, reducing the risk of sudden unexpected infant death, a new study has found.
Transgender people who are married are less likely to experience discrimination than their unmarried counterparts, indicates a national study led by a Michigan State University sociologist.
Scientists from the Memorial Sloan Kettering Cancer Center, US, have revealed a communication system between the knee joint and developing bones in mice, which controls bone growth during early development and after injury.
A new study has shown that infusion of a broadly neutralizing antibody VRC01 in virally suppressed, early treated volunteers was associated with a modestly delayed rebound of HIV after interruption of antiretroviral therapy.
A lack of variation in the stress hormone cortisol from morning to evening is tied to a wide range of negative health conditions, including inflammation and immune system dysfunction, new Northwestern University research suggests. In the first comprehensive review of the relationship between daily cortisol fluctuations and health, researchers at the School of Education and Social Policy combined data from 80 different studies to show that while cortisol levels matter, a lack of variation from morning to evening may be even more telling.
Using cheese as a novel way to study microscopic communities, researchers have found that bacteria living on artisanal cheese varieties have transferred thousands of genes between each other. They also identified regional hotspots where such exchanges take place, including several genomic "islands" that host exchanges across several species of bacteria. Microbiome communities are known to play a key function in many areas, including human health, protecting us from some diseases and amplifying others.
Study results released today by the HIV Prevention Trials Network (HPTN) show long-acting injectable cabotegravir (CAB LA) to be well tolerated by men and women and support the dosing schedule currently being used in a phase 3 HPTN study for HIV prevention.
A pattern of escalating marijuana use in adolescents is linked to higher rates of depression and lower educational accomplishments in adulthood.
