The water here refused to boil, so the scientists decided to add some ice
If you want to boil the water, use a heat source to heat the water, but if the heat source is too hot, the water will no longer absorb heat. This is called the "Leighton Frost effect", and because of this effect, water is not a very good heat transfer medium when it is needed to cool high-temperature objects quickly. A recent study offers an alternative: instead of using water, use ice for heat transfer.

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.
