New reactor design lessens risk of weapon proliferation
Nuclear materials for power reactors cannot be stolen by those interested in using it for nuclear weapons while the material is in the reactor — it is too hot to handle; the risks of diversion are during the enrichment process, and while the material is being transported; to lessen the risk, researchers offer innovative reactor design

More on the danger of GPS spoofing
The military version of GPS includes security features such as encryption, but civilian signals are transmitted in the clear, unencrypted; a suitcase-size transmitting device can easily fool a GPS receiver; the power grid may be disrupted, and ankle-bracelet-wearing criminals walk about freely

Breakthrough: Radioactive waste may no longer be dangerous to store
Aussie researchers have created a material which has the potential to filter and safely lock away radioactive ions from waste water; nanofibers which are millionths of a millimeter in size could permanently lock away radioactive cations by displacing the existing sodium ions in the fiber

Invisibility cloak as a protection against tsunamis
Rather than fortifying sea platforms and coastal towns to withstand tsunamis, it may be possible to use invisibility cloaks to make off-shore platforms, islands, and even cities “invisible” to waves

The long view
Helping Strengthen America’s Critical Infrastructure
Everyday life depends on a robust infrastructure network that provides access to running water, communications technology and electricity, among other basic necessities. The experts who keep our national infrastructure secure and resilient also need a strong network to share their knowledge and train the next generation of professionals capable of solving complex infrastructure challenges.
AI and the Future of the U.S. Electric Grid
Despite its age, the U.S. electric grid remains one of the great workhorses of modern life. Whether it can maintain that performance over the next few years may determine how well the U.S. competes in an AI-driven world.
