In stunning new time-lapse videos, biological nanoparticles scoot and flit across a starry field of glowing dots. Guided by the invisible chemistry of attraction, these microscopic travelers eventually group together to form perfectly round, glowing circles on a black surface. These mesmerizing new videos are made possible with LEVA (light-induced extracellular vesicle and particle adsorption), a…

Within the combat towards most cancers, an vital subject of analysis is the seek for protected alternate options to chemotherapy and radiotherapy. These remedies assault each most cancers cells and wholesome cells, exposing sufferers to critical unintended effects. A workforce of scientists from the College of Texas at Austin and the College of Porto in Portugal have simply introduced an…

Light-based strategy effectively treats carbon monoxide poisoning in rats — ScienceDaily

Carbon monoxide (CO)–which is produced by cars and trucks, as well as fires and explosions–is a toxic, colorless, and odorless gas, and there are more than 50,000 admissions to US emergency rooms due to CO poisoning each year, with many cases involving damaged airways and lungs. Investigators at Massachusetts General Hospital (MGH) recently developed a phototherapy strategy that was highly…

Researchers at Duke University, OSU, and Oak Ridge National Laboratory have solved one of the biggest problems with new forms of quantum encryption: quantum key distribution. QKD is the process of distributing keys during a transmission and in a way that will tell both sides of the conversation that someone is eavesdropping. The new system, which uses lasers to transmit multiple bits at…
