In a landmark study, Chinese scientists report the successful transmission of entangled photons between suborbital space and Earth. Furthermore, whereas the previous record for successful entanglement distribution was about 100 kilometers (km), here, transmission over a distance of more than 1,200 km was achieved. The distribution of quantum entanglement, especially across vast distances, holds important…
The Debut of a Robotic Stingray, Powered by Light-activated Rat Cells
Researchers have created a robotic mimic of a stingray that’s powered and guided by light-sensitive rat heart cells. The work exhibits a new method for building bio-inspired robots by means of tissue engineering. Batoid fish, which include stingrays, are distinguished by their flat bodies and long, wing-like fins that extend from their heads. These fins…
