Plant hormones influence growth and development by acting on specific cells and tissues. However, determining precisely where and when a hormone needs to act has been challenging because conventional hormone treatment generally activates signaling throughout the plant.

At any given moment, a U.S. Air Force pilot may be maneuvering an aircraft midmission, a U.S. Navy officer resurfacing a submarine after weeks undersea or a U.S. Army technician offloading drone data in a combat zone. Each operation depends on satellite communications (satcom) and, specifically, on cryptographic keys that allow terminals to communicate securely while keeping adversaries locked out.

AI data centers need to move lots of information quickly, and the demand for faster data transmission is only growing. Over very short distances, data centers can use traditional copper wires to connect chips right next to one another. But over distances longer than 1 m (3.3 feet), the connection requires fiber optic cables.

Stanford researchers recently revealed how a seemingly physics-defying wireless communication technology works. The new technology, called thermal noise communication, harnesses background static that normally is the bane of radio, cellular and other wireless signals. In their new study published in the Proceedings of the National Academy of Sciences, the team showed how a transmitter could deliver data to a receiver without any actively produced signal by manipulating tiny oscillations in volta
