In a major breakthrough in the fields of nanophotonics and ultrafast optics, a Sandia National Laboratories research team has demonstrated the ability to dynamically steer light pulses from conventional, so-called incoherent light sources.

This ability to control light using a semiconductor device could allow low-power, relatively inexpensive sources like LEDs or flashlight bulbs to replace more powerful laser beams in new technologies such as holograms, remote sensing, self-driving cars an...

New research conducted as part of the science verification phase of the Visible Spectropolarimeter (ViSP) instrument at the National Science Foundation’s Daniel K. Inouye Solar Telescope is the first to use data from this instrument. It is hoped that the work will pave the way for future studies to enable a better understanding of the potential risks to key power and communications infrastructure.

The study, which is published in The Astrophysical Journal Letters, was the result of an exciting collaboration between the U.K. and the National Science Foundation and marks an important milestone for the astronomical community and this ground-breaking telescope.

In experiments with mice and humans, a team led by Johns Hopkins Medicine researchers says it has identified a particular intestinal immune cell that impacts the gut microbiome, which in turn may affect brain functions linked to stress-induced disorders such as depression. Targeting changes mediated by these immune cells in the gut, with drugs or other therapies, could potentially bring about new ways to treat depression.

The findings of the study were published March 20, 2023 in the journal Nature Immunology.

“The results of our study highlight the previously unrecognized role of intestinal gamma delta T cells (γδ T cells) in modifying psychological stress responses, and the importance of a protein receptor known as dectin-1, found on the surface of immune c...

May lead to devices with ‘unmatched’ energy efficiency and memory storage density. University of Minnesota Twin Cities researchers, along with a team at the National Institute of Standards and Technology (NIST), have developed a breakthrough process for making spintronic devices that has the potential to become the new industry standard for semiconductors chips that make up computers, smartphones, and many other electronics...
