Some details of the smartphone were printed on a 3D printer. The engineer also configured iOS for a foldable form factor. The enthusiast admitted that the most difficult thing was to turn the original display into a flexible one. Often the screens failed after the first closure of the lid.

For the first time in human history, artificial blood was transfused.

Red blood cells were grown from human blood samples from the UK National Health Service donor database. First, stem cells were isolated from the biomaterial, and then they were differentiated. Unlike ordinary ones, all artificial erythrocytes are young - in the real blood of donors there are cells of different ages. Volunteers received 5-10 milliliters of liquid with them - 1-2 teaspoons. Artificial red blood cells can be transfused to people with anemia and other blood diseases, as well as to patients with rare groups.

It is not yet known how macaques will behave in space. In cramped cages on Earth, they feel uncomfortable: they begin to pull out their hair, refuse food or activity. In addition, rocket flying can be very scary for monkeys. “On the ground, a panicking monkey can be calmed down with toys, music, or just the company of relatives. How to take care of the happiness and comfort of a monkey in space is a new challenge for astronauts,” said one of the scientists.

Xiaomi has unveiled the world's first smartphone with a Leica lens mount.

This is a modified version of Xiaomi 12S Ultra, in which two inch sensors were installed at once. One is normal, and the one located in the center does not have its own optics - it is used only with a lens attached. There is also a wide-angle camera, but Xiaomi did not say anything about it. There is no data on technical characteristics, since the smartphone is in concept status. It is possible that it will never go on sale, but the company may well use the developments in one of the future devices.

A professional chess player can burn up to 560 calories in a two hour game.

This is almost the same as what you would spend running 8 km. Where did the data come from: at one of the chess festivals, the organizers connected devices to Russian grandmaster Mikhail Antipov that measured the player’s heart rate and breathing rate. So they found out that it was exactly so many calories that he burned in a couple of hours of the game. No wonder chess players are called athletes. And it seems that soon they will overtake footballers in popularity.
