Cryptographic coprocessors are nice, for the most part. These are small chips you connect over I2C or One-Wire, with a whole bunch of cryptographic features implemented. They can hash data, securely ...

Physicists have built a tractor beam out of lasers that can both repel and attract objects across distances 100 times farther than previously possible. Michelle Starr is CNET's science editor, and she ...

ZEUS is expected to produce even higher levels of power later this year. The school gym-sized ZEUS is the successor to the university’s HERCULES system, which topped out at 300 terawatts. ZEUS relied ...

Lightning rods have been used to guide lightning strikes for centuries, but now scientists have demonstrated something a bit more advanced than a humble metal stick. Beaming a high-powered laser into ...

The Iron Beam is the most advanced, operational laser in the world, though England, the US, and others have relatively advanced lasers. In a historic breakthrough, the IDF on Wednesday announced that ...

The University of Michigan plans to begin experimenting with a new high-power laser that will eventually become the strongest laser in America, according to the researchers. The Zettawatt-Equivalent ...

Laser processes with dynamic beam shaping create stable joints even in challenging material combinations. Recent applications demonstrate how to eliminate filler materials while improving quality, ...
