There was a way to measure the level of oxygen in the blood using a smartphone camera.

American scientists have figured out how to use a smartphone camera to measure saturation - the level of oxygen saturation in the blood. Usually, doctors use a pulse oximeter for this - a small device that resembles a clothespin and is worn on a finger. To measure saturation with a smartphone, you need to put your fingertip on the camera. There, flashes of red, green and blue will turn on in turn. The process will take about 15 minutes. The camera will record how, with each heartbeat, blood flows over the illuminated part of the finger and absorbs the light from the flash. Based on this data, specially trained artificial intelligence will calculate the level of oxygen in the blood.

In Belgium, judges and prosecutors went to jail to check on conditions.

The Belgian Ministry of Justice decided to conduct an experiment - 55 prosecutors and judges sat in a new prison in Brussels for a while to test the conditions of detention and feel like prisoners. It is expected that after that they will issue more reasonable sentences. While the new 1200-seat prison has not yet opened, there are no real criminals in it. The guards treat prosecutors and judges like real prisoners. The conditions of their stay are as close to real as possible.

In South Korea, the “artificial sun” was heated to 100 million ° C: this is 7 times hotter than the stars.

Engineers managed to heat up the reactor to 100 million degrees Celsius. This is seven times the temperature of the Sun. The heated plasma was held for 30 seconds. The scientists' next goal is 300 seconds. The principle of operation of a nuclear reactor is completely copied from the Sun. The device uses nuclear fusion in the same way to obtain infinite energy. The reactor is located in KSTAR. It is planned to be used for energy production in times of crisis. One such "artificial sun" can provide energy to entire cities and small countries. The cost of this "monster" remains unknown.

Modular robot Yarbo mows grass, removes snow and blows leaves.

All three modules are equipped with a millimeter-wave radar and a camera that allow the robot to detect and avoid obstacles. Yarbo navigates within a predetermined working area using GPS. It reportedly independently determines which path to follow in order to cover the area most effectively. The battery recharges wirelessly and operates in temperatures down to -30º C. One 2-hour charge is claimed to last for 2 hours of mowing, 90 minutes of snow removal or 50 minutes of leaf removal. On Kickstarter, the Yarbo has a starting price of $2,599 for the mower-module variant (estimated retail price of $4,399). For the model with all three modules - $3,699 (retail price $6,999). Deliveries should begin in December this year.

Now the robot can decide whether to laugh back and what type of laugh is appropriate for a particular situation. The naturalness and appropriateness of Erica's laughter was appreciated by 130 volunteers who were given the recordings to listen to. Most of them felt that the android showed empathy, humanity and understanding.

The threat of artificial intelligence.

Researchers from the University of Oxford analyzed the prospects for superintelligent artificial intelligence and concluded that it will accelerate the death of mankind. The fact is that such AI will be able to foresee the steps of individual countries and organizations for decades to come. If desired, he simply destroys them in the bud. And for this, an army of "Terminators" is not even needed - a couple of dozen viruses are enough. You also need to consider that the resources on the planet are finite. And when another intelligent species appears on Earth - and AI definitely is - competition will begin. Which, alas, may not end in our favor.
