Breakthrough: Acoustic cloak theoretically possible
Invisibility cloak — deflecting microwaves around a cloaked object and restoring them on the other side, as if they had passed through empty space — has already been demonstrated; Duke researcher now shows that an acoustic cloak is theoretically feasible: Sound waves would travel seamlessly around the cloaked object and emerge on the other side without distortion; submarines could be hidden from sonar

The long view
Nuclear Has Changed. Will the U.S. Change with It?
Fueled by artificial intelligence, cloud service providers, and ambitious new climate regulations, U.S. demand for carbon-free electricity is on the rise. In response, analysts and lawmakers are taking a fresh look at a controversial energy source: nuclear power.
Huge Areas May Face Possibly Fatal Heat Waves if Warming Continues
A new assessment warns that if Earth’s average temperature reaches 2 degrees C over the preindustrial average, widespread areas may become too hot during extreme heat events for many people to survive without artificial cooling.
Exploring the New Nuclear Energy Landscape
In the last few years, the U.S. has seen a resurgence of interest in nuclear energy and its potential for helping meet the nation’s growing demands for clean electricity and energy security. Meanwhile, nuclear energy technologies themselves have advanced, opening up new possibilities for their use.
