Adding engineered human blood vessel-forming cells to islet transplants boosted the survival of the insulin-producing cells and reversed diabetes in a preclinical study. The new approach, which requires further development and testing, could someday enable the much wider use of islet transplants to cure diabetes. Read more ›

Perovskite solar cells are highly efficient and low cost in production. However, they still lack stability over the decades under real weather conditions. An international research collaboration has now explored the effects of multiple thermal cycles on microstructures and interactions between different layers of perovskite solar cells. They conclude that thermal stress is the decisive factor in the degradation of metal-halide perovskites. Based on this, they derive the most promising... Read more ›

Only two births of a blue whale have ever been recorded. Mother and calf pairs are also sighted much more rarely than might be expected. The reason, new research suggests, has to do with where and when blue whales spend their first months of life. Read more ›

Researchers have investigated how microbubbles tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how tiny cyclic microjets liquid jets generated by microbubbles penetrate the cell membrane enabling the drug uptake. Read more ›

Infection with Zika virus in pregnancy can lead to neurological disorders, fetal abnormalities and fetal death. Until now, how the virus manages to cross the placenta, which nurtures the developing fetus and forms a strong barrier against microbes and chemicals that could harm the fetus, has not been clear. Researchers now report a strategy Zika virus uses to covertly spread in placental cells, raising little alarm in the immune system. Read more ›

Researchers have pioneered a new catalytic transformation that converts epoxides into fluorinated oxetanes, a coveted but difficult-to-make class of drug molecules that escaped synthetic preparation for years. By unlocking a pathway to these valuable drug scaffolds, this discovery potentially opens the door to new medicines for drug discovery applications. Read more ›

Photonics researchers have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light's structure with great potential for advanced optical communication systems. In addition, a new type of space-time duality is explored for powerful analogies bridging different fields of optics. Read more ›

Seeking mental health help is a significant step, but that first intake session can often feel more like paperwork than progress, and a significant proportion of people 'drop out' or never return for a second visit, previous research has shown. In a new review investigators confirmed that single-session interventions (SSIs) can significantly improve mental health outcomes in both youth and adults. Common in other countries but not the U.S., an... Read more ›

Biologists, using a technique that explores both genes and structural characteristics, have introduced 10 new species of marine sponge. Despite their distinction as one of Earth's oldest lifeforms and the key role they play in sustaining coral reef ecosystems, marine sponges are vastly understudied. Read more ›

Human evolution has revolved around food, from identifying and foraging for it to growing and preparing it. Researchers have identified a region in the brain's visual cortex that responds to food and have developed a theoretical framework that could explain the origins of this selectivity. The team outlines how visual and nonvisual signals contribute to the brain's cortical responses when people were shown images of food. Researchers also found that... Read more ›
