Researchers claim to have transferred a memory between two sea slugs

Enlarge / An Aplysia, also known as a sea hare. (credit: Jerry Kirkhart) How does a brain hold on to a memory? There’s evidence for a number of processes, from potentially transient changes in gene expression, through long-term changes in DNA packaging, and up to alterations of the connections among cells. Complicating matters further, none […]

Researchers find a gene that lets bacteria kill all male flies

Enlarge (credit: Katja Schulz) A number of bacteria that infect insects have a simple and brutal way of increasing their transmission: they kill off all the male progeny of the females that they infect. There’s actually some evolutionary logic to this. The bacteria can get transmitted to the eggs of the females they infect but […]

Army researchers find the best cyber teams are antisocial cyber teams

Enlarge / Members of the University of Maryland Baltimore County CyberDawgs team primarily focus on working rather than interacting. This fits with US Army Research Laboratory findings, as this was the highest performing team at the Mid-Atlantic (and National) National Collegiate Cyber Defense Competition in 2017.

Researchers say some Android phone makers hide missed updates

A number of Android phones have a tendency to skip the occasional security patch while making it appear that the device is fully up to date, Wired reports. Researchers with Security Research Labs (SRL) looked into 1,200 phones from manufacturers like Google, Samsung, Sony, Nokia, Huawei, Motorola, LG, HTC, ZTE and TCL and found that […]

Researchers use machine learning to quickly detect video face swaps

We all know that AI can be used to swap faces in photos and videos. People have, of course, taken advantage of this tool for some disturbing uses, including face-swapping people into pornographic videos — the ultimate revenge porn. But if AI can be used to face swap, can’t it also be used to detect […]
