Deepfakes now come with a realistic heartbeat, making them harder to unmask

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.

The bear in the (court)room: who decides on removing grizzly bears from the endangered species list?

In a new Frontiers in Conservation Science article, Dr Kelly Dunning discusses the politicization of wildlife management. The team analyzed hundreds of documents to track the case of grizzlies being taken off or staying on the list of endangered species. This editorial highlights some of the issues that come with wildlife management becoming ever more political.
