Is the wound worsening or is it healing? this new bandage can tell you
If bacteria invade our bodies from the wound, they will really threaten our lives unless they can be detected as soon as possible. Now, a new type of sensor that can be mounted on bandages alerts nearby bound smartphones when it detects that bacterial content has entered a dangerous range that needs to be alerted.

By the time you read this article, the two hottest ice piers in the official Olympic flagship online store have been sold out.
In 2022, Bingdun, the mascot of the Beijing Winter Olympic Games, really became the top stream, captivating a large number of athletes and journalists, and then making a hot search with "Carmen" and "shaking Snow". Obviously, in the cold winter, no one can refuse a "rock candy roll". But why can the ice pier be so cute "straight to the heart"?

Standard quantum theory is over. There is a huge problem with standard quantum theory, which cannot even calculate the exact time for particles to move between two points. Physicists can only use hybrid algorithms to solve this problem. The emergence of Bohm mechanics changed that. Today, advances in technology have made it possible for physicists to verify Bohm mechanics, and the subsequent progress has renewed physicists' attention.

Playing Sudoku in the Quantum World: physicists have found the answer to a mathematical puzzle judged to be unsolved
Mathematician Euler put forward a problem of 36 officers similar to 6 × 6 Sudoku: 36 officers of six different ranks were selected from each of the six legions, and these 36 officers were arranged into a phalanx. Can the legions and ranks of officers in each row and column belong to different legions and ranks? later, mathematicians proved that similar problems of order 5 and order 7 could be solved, but there was no solution at order 6. Later, a group of physicists wondered: if every officer is in a superposition of two legions and two ranks, is there a solution to this problem? they really found a quantum solution.

Robot Can grab the "paper-cut" hand of raw egg yolk The art of three-dimensional origami makes the two-dimensional sheet material form a three-dimensional structure by cutting and folding. However, it is still very difficult to reverse design the shape and cutting method of the two-dimensional sheet according to the required three-dimensional structure, especially the three-dimensional structure with complex curved surface. However, a recent study in the journal Nature Communications suggests a new way to solve this problem.

Medical science The robot performs laparoscopic surgery on pigs without human help. Enterostomy is one of the most challenging tasks in gastrointestinal surgery, which requires surgeons to sew the window accurately and steadily. Even the slightest hand shaking or misplaced needle can lead to leakage and may bring catastrophic complications to the patient. Recently, Johns Hopkins University has developed an intelligent tissue autonomous robot, STAR, which has successfully performed laparoscopic operations such as intestinal anastomosis in pigs without human guidance. The research is published in the journal Scientific Robotics.
