Are Deepfakes Overblown?

I’ve worked in and out of security for decades. We did the same kinds of things people do with deepfakes with far older technology when I was working on the switchboard at my friend’s motel when I was a kid. Back then, all we had were hard-wired phones, but we’d often mess with people late at night by pretending to be people we weren’t.

After three years on Mars, NASA's Ingenuity helicopter mission ends

NASA's history-making Ingenuity Mars Helicopter has ended its mission at the Red Planet after surpassing expectations and making dozens more flights than planned. While the helicopter remains upright and in communication with ground controllers, imagery of its Jan. 18 flight sent to Earth this week indicates one or more of its rotor blades sustained damage during landing and it is no longer capable of flight.

Cellular scaffolding rewired to make microscopic railways

Princeton researchers have learned to harness the gossamer scaffolding that maintains the structure of living cells and used it to develop a nanotechnology platform. The technique eventually could lead to advances in soft robotics, new medicines, and the development of synthetic systems for high-precision biomolecular transport.

Fingerprinting biomolecules with the help of sound

A team of researchers from the Institute for Optoelectronic Systems and Microtechnology at Universidad Politécnica de Madrid (UPM) has designed a biosensor capable of identifying proteins and peptides in quantities as low as a single monolayer. For that, a surface acoustic wave (SAW), a kind of electrically controlled nano earthquake on a chip, is generated with an integrated transducer to act on a stack of 2D materials coated with the biomolecules to be detected.
