Trampled cockroaches do not clean up, why the next day is gone? Experts: it was companions "carried away"
The day and night of the cockroaches were very annoying, obviously before going to bed and stepping on a dead, would have liked to clean up the next day, the results came to the next day to see, found that the stepped on dead cockroaches disappeared. In this scene, let yourself sleep, the mind is also constantly thinking back, stepped on the dead cockroaches in the end where it went?

The future world, how humans face dangerous creatures
In the world of the future, the total number of humans is rapidly decreasing due to the growing spread of plague and the dangers of new species, and most of the remaining people are entering the high-walled cities to live in for shelter.

Seven islands in the world with the most shark attacks, how many do you know?
Sharks are the top predators in the ocean, often preying on small fish, seahorses, and other small animals in the ocean's vast ecosystem, and occasionally on humans. Although shark attacks on humans are relatively rare, shark attacks on humans occur around the world every year, and in this issue, we take a look at the seven islands with the most shark attacks in the world.

When you have enough to eat, go again. Hey.
Take in nutrition and applaud for love. It's Valentine's Day again. Most of the humans in the restaurant are in pairs, enjoying the food while expressing their love. A meal is probably enough to pave the way for evening activities.

"sex" is secretly taking place in your intestines.
The microbes in our gut have "sex" on a regular basis, which is good for both bacteria and us. As you may know, there are a lot of bacteria living in our intestines. What you may not know is that in order to survive better, these bacteria have "sex" on a regular basis.

The problem of how to turn a circle into a square has perplexed mathematicians for thousands of years.
The reason why this problem is difficult to answer is that it is not only a geometry problem, but also an algebra problem. In the problem of drawing with rulers and compasses, given a number of angles or length of line segments, the essence is to give some real numbers, while the rule of drawing with non-graduated rulers and compasses ensures the length of the angles or segments made, which is the combination of sum, difference, product, quotient and square root of a given real number. As a result, each ruler drawing problem actually corresponds to an algebraic problem.

Physics The latest LHAASO experiment verifies the correctness of space-time symmetry in Einstein's theory of relativity. But there are very high-energy processes in celestial activity. When the high-altitude large cosmic ray experiment LHAASO in Daocheng, Sichuan Province was not fully completed in 2021, it detected the gamma ray photons with the highest energy known to mankind, with an energy of 1.4 × 10 GeV. The LHAASO team used its observed high-energy gamma-ray cases to test the Lorentz symmetry. The experimental results increase the breaking energy scale of Lorentz symmetry by about 10 times, which is the strictest test of this kind of Lorentz symmetry, and once again verifies the correctness of Einstein's relativistic space-time symmetry. The relevant results are published in the latest issue of physical Review KuaiBao. (Institute of High Energy, Chinese Academy of Sciences)

Point Nemo
This is the remotest region of the world. Geographically so remote, there is no human traffic. How will it stay? Raise your hand to space! Even in broad daylight, the silence of the crematorium prevails here. Geographers say, 'Point of Nemo.' The Latin 'nemo' means 'not one'. Maybe it is named because it is uninhabited. There is another name. Inaccessible oceanic poles. The Pacific island region between Australia, New Zealand and South Africa is known by many as the domain of NASA. Because many of NASA's spaceships are located at this 'Point of Nemo'. Yes, the place is literally a spacecraft graveyard. At 360 kilometers above Earth, this Nemo region is the closest to Earth, where the International Space Station is located. When the spacecraft is running out of power, or without risking a malfunction, it is sent straight into the Nimo. If it is a small spaceship, it gets dusty before returning to Earth. But, when the spacecraft grows up, this Nemo is carefully sent into eternal sleep. Recently, the Chinese Space Research Organization announced that their 7,700 kg space laboratory will crash into the earth. This is going to happen any day between October this year and April next year. China has no way of sending this spacecraft to Nimoy. Those who held the reins were disoriented. Where it is going to fall, Chinese space scientists do not know.

Will November economic recovery and sustainability summits deliver?
November is a pivotal month for sustainably as the Climate Summit COP27 brings over 150 heads of states to Egypt to advance decarbonization. COP27 will be followed by the G20 summit bringing the 20 most industrialized economies to Indonesia to promote economic recovery and Green-Growth transition.
