Robots with weapons against criminals

The San Francisco police asked the city council to allow the use of robots with lethal weapons against criminals. The document provides for permission to kill people in cases “when the risk of death of ordinary citizens or officers is inevitable and any other forceful option available to the police loses to this scenario.” The preliminary version of the project has already been approved, and now it must be considered by a special commission. Now police robots are mainly used for bomb disposal, however, some models can be additionally equipped with 12-gauge guns.

Unusual neural network

Stanford University specialists presented the Editable Dance Generation from Music neural network, which can generate realistic dance movements based on the music being played. The physical plausibility is amazing - the technology takes into account the time of contact and foot with the ground, as well as the possibility of sliding on the surface. In addition, in EDGE you can set certain movements to start the dance; use only some parts of the body, limit movements to a given space.

Heated and waterproof scarf from Xiaomi.

The accessory is powered by a power bank and can heat up in a few seconds to one of the set temperatures - 38, 45 or 50 degrees.

Mercedes has introduced a subscription to accelerate to 100 km / h 0.9 seconds faster for some cars for $ 1,200 per year.

The Acceleration Increase feature, for an additional fee, allows drivers to access improved engine performance that their car is already capable of from the factory. The Acceleration Boost subscription programmatically increases the power of Mercedes-EQ EQE 350 4MATIC, Mercedes-EQ EQE SUV 350 4MATIC and Mercedes-EQ EQS SUV 450 4MATIC electric vehicles by 20-24%, increasing torque and reducing it by about 0.8-0, 9 seconds acceleration from zero to 100 km / h.

Scientists have created the first artificial black hole.

It is not entirely natural - with the help of a chain of atoms, only the event horizon was recreated. However, the discovery is fundamental - finally, the presence of Hawking radiation around black holes has been experimentally confirmed. This means that there are chances to finally connect classical physics with quantum physics.

Scientists will test our reality for simulation using supercomputers.

Sciencealert published an article with new approaches to the issue of simulation. It is proposed to look for physical characteristics of the information, and if they are found, try to hack the simulation from the inside, causing the program to crash.

John McFall will be the first disabled person in space.

Paralyzed people have learned to control a wheelchair with the power of thought.

In Texas, scientists have created a wheelchair that paralyzed people can control with their minds. Some volunteers achieved 98% accuracy after the training course. Paralyzed people controlled the direction of the wheelchair by thinking about the movement of body parts. For example, thinking about hands for turning left or legs for turning right. The computer read the volunteers' neural signals and turned them into wheelchair commands. Initially, patients controlled the wheelchair with an accuracy of 43-55%. After training, some had an indicator of 98%. Each volunteer trained three times a week for 2-5 months.
