Future computer, sensing, and encryption technologies may become noticeably smaller and more potent thanks to an ultrathin creation that enables scientists to manage the bizarre but useful quantum mechanical phenomenon. New research that was just released in the journal Science describes the device. According to researchers at Sandia National Laboratories and the Max Planck Institute for the Science of Light, this gadget might replace a large collection of apparatus used to link photons in the peculiar quantum phenomenon known as entanglement. It is a type of metasurface, a nano-engineered substance that opens the door to intricate photon entanglement not before feasible with compact technology. When photons are considered to be entangled, it indicates that they are connected in a way that actions on one of them have an impact on the other, regardless of their location or distance from one another in the universe. It is a strange consequence of quantum mechanics, the physical principle...

In a proof-of-concept study, University of Pennsylvania researchers showed that dental plaque and germs that cause tooth decay could be successfully treated and removed by a hands-free device. In the future, a shape-changing robotic microswarm could replace the need for separate toothbrushes, rinses, and dental floss. The technology, developed by a multidisciplinary team at the University of Pennsylvania, may offer a fresh, automated way to do the daily tasks of brushing and flossing, which are tedious but crucial. This technique could be very beneficial for persons who lack the physical dexterity to effectively clean their teeth on their own. Iron oxide nanoparticles with catalytic and magnetic characteristics make up these tiny robots. Using a magnetic field, scientists were able to manipulate their motion and design, producing either elongated threads that can slide between teeth like floss or bristle-like structures that remove dental plaque off the vast surfaces of teeth. In both ...
