Neutron scattering at Oak Ridge National Laboratory has revealed, in real time, the fundamental mechanisms behind the conversion of sunlight into energy in hybrid perovskite materials. A better understanding of this behavior will enable manufacturers to design solar cells with significantly increased efficiency.

From energy materials to disease diagnostics, new microscopy techniques can provide more nuanced insight. Researchers first need to understand the effects of radiation on samples, which is possible with a new device that holds tightly sealed liquid cell samples for transmission electron microscopy.

As an undergraduate, Tejaswini Yelamanchili used to spend hours a day playing video games like Counter-Strike and Age of Empires. Time would speed by – hours seemed like minutes – as she focused on the process of gaming. Now a graduate student at Missouri S&T, she’s spending much of her time getting others into gaming as part of her research to better understand how the brain works when players are in the zone.

Many soldiers returning from combat bear visible scars, or even lost limbs, caused by blasts from improvised explosive devices, or IEDs. However, some servicemen also return with debilitating hidden injuries -- the loss of all or part of their genitals. Now, the Johns Hopkins reconstructive surgery team that performed the country's first bilateral arm transplant in a wounded warrior has successfully performed the first total penis and scrotum transplant in the world.

While the health effects of breastfeeding are well-recognized and apply to both mothers and children, some mothers may not be able to produce a milk supply to meet the needs of their child. When infants require hospitalization in the immediate newborn period doing to being born preterm or having other health complications, human milk is a vital life-saving medical intervention.

A team led by Columbia University Biomedical Engineering Professor Gordana Vunjak-Novakovic has designed a creative new approach to help injured hearts regenerate by applying extracellular vesicles secreted by cardiomyocytes rather than implanting the cells. The study shows that the cardiomyocytes derived from human pluripotent stem cells (derived in turn from a small sample of blood) could be a powerful, untapped source of therapeutic microvesicles that could lead to safe and effective treatments of damaged hearts.
