Briefly informed: Pentagon leak, care robots, Twitter, AR opera glasses

In their search for the author of the massive secret service data leak, US investigators seem to have found the leak. The FBI arrested a 21-year-old member of the National Guard in Massachusetts. Attorney General Merrick Garland said the man was taken into custody in connection with the “unauthorized removal, storage and transmission of classified information.” US media had reported that he led a chat group on the Discord platform popular with video gamers. Around two dozen young people with a penchant for weapons and military equipment had joined forces there. The 21-year-old initially shared the explosive documents with the group as copies and later uploaded photos of printed documents there. There is still no clear picture of the motivation.

A research team from Stanford University’s ILIAD Labs has succeeded in developing a robot that can feed people with spinal cord injuries or other motor disabilities. The robot is able to pick up almost any food and put it into the mouth of the person in need of care. Conventional robots are limited when it comes to shoving food straight into their mouths. This is where the three-armed robot from Stanford University comes in. The first robotic arm uses a fork to test the consistency of the food before impaling it. The second robotic arm pushes it onto the spoon of a third robotic arm. Finally, he inserts the spoon into the patient’s mouth at an optimized angle.

The publicly funded TV channel PBS has become the second US broadcaster to stop its activity on Twitter because of a controversy with owner Elon Musk. Twitter flagged PBS as a state-funded media organization, as did broadcaster NPR. The broadcasters find this misleading, since state funds only make up a small part of the financing. Since the change, PBS has not tweeted and has no plans to do so, a spokesman told Bloomberg. NPR also no longer wants to provide the more than 50 user accounts on Twitter with new content until further notice.

The opera glasses are going digital: for the first time, classical music fans can immerse themselves in a digital world with augmented reality glasses at the Düsseldorf Opera on the Rhine during a performance of “Die tote Stadt”. The audience can have information about the piece, music and soloists played digitally or take a look into the orchestra pit. However, the number of glasses is currently limited to 30. AR glasses are also to be used at the Bayreuth Festival this summer in a “Parsifal” production.
