Current algorithms for the detection of deepfakes increasingly rely on remote pulse reading to distinguish them from genuine videos of people. Here, scientists show for the first time that the most recent deepfakes feature a global pulse rate which appears realistic. This worrying development makes it necessary for deepfake detectors to become more powerful, for example, by focusing on local variations in blood flow within the face.

Researchers have created a light-powered soft robot that can carry loads through the air along established tracks, similar to cable cars or aerial trams. The soft robot operates autonomously, can climb slopes at angles of up to 80 degrees, and can carry loads up to 12 times its weight.

You might have heard of Tor in the news a few times, yet never dared to try it yourself. Despite being around for decades, Tor is still a tool too few people know about.
