Smart food label can identify bacteria without opening the package
Food-safe microneedles incorporated into a new smart label can effectively collect samples from packaged food and inform consumers about its quality in real time. Velcro-like food sensor, made from an array of…
Planet-forming disc torn apart by its three central stars
New observations allowed astronomers to see, for the first time, the shadow of GW Orionis’ inner ring, which helped them figure out its 3D orientation. GW Orionis, a triple star system with…
Stealthy microrobots that can evade the immune system
Zwitterionic polymers allow researchers to fabricate drug-carrying microrobots that can operate covertly under the immune system’s radar. Microrobots have the potential to radically change the future of medicine. Their small bodies and…
