The hogfish can go from white to reddish in milliseconds as it adjusts to shifting conditions in the ocean. Scientists have long suspected that animals with quick-changing colors don’t just rely on their eyes to tune their appearance to their surroundings — they also sense light with their skin. But exactly how remains a mystery. A study reveals that hogfish skin senses light differently from eyes.
Creating enough nanovesicles to inexpensively serve as a drug delivery system may be as simple as putting the cells through a sieve, according to an international team of researchers who used mouse autologous — their own — immune cells to create large amounts of fillable nanovesicles to deliver drugs to tumors in mice.
For the first time, researchers have found a way to use a concept called ‘flying focus’ to better control the intensity of lasers over longer distances. Their technique includes capturing some of the fastest movies ever recorded and has the potential to help researchers design the next generation of high-power lasers or produce light sources with novel wavelengths.
Researchers have designed a new molecule-building method that uses sulfones as partners for cross-coupling reactions, or the joining of two distinct chemical entities in a programmed fashion aided by a catalyst.
One of the recurring media narratives about the nature of science today is that it is ‘broken’ or ‘in crisis.’ But an analysis of how the media cover science news argues that generalizations about a crisis in science aren’t justified by the available evidence. The essay proposes that those who communicate science, including journalists, scholars and scientists themselves, should more accurately convey its investigatory nature, the self-correction process, and corrective measures without legitimizing a faulty narrative.
