Rodents take nature away, how do we get it back?
About 1000 years ago, the island where New Zealand is located is still a wild land. Birds, reptiles and invertebrates still thrive in this dense forest hundreds of kilometers away from other continents. But in the 13th century, when the Maori migrated to New Zealand, they also brought Polynesian rats (Polynesian rats) as food. Since then, humans and rodents have begun to change the ecological balance of New Zealand, while native species have begun to become extinct.

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.

Neuroscience The neural mechanism that drives social behavior For social animals, loneliness and social isolation can lead to stress, while social isolation increases the risk of depression, substance abuse, obesity and premature death. However, the neural mechanism of coordinating perception and seeking social activities is not clear. Scientists have found that islet amylin produced by neurons in the medial preoptic area (MPOA) of the brain of female mammals drives their parenting behavior. Recently, a study published in the journal Nature Communications found that the islet amylin-calcitonin receptor signal pathway in MPOA mediates social behavior in mice.

Health Get enough sleep or lose weight At present, scientists believe that the main cause of obesity is increased calorie intake rather than lack of exercise. Previous studies have shown that lack of sleep affects appetite regulation, leading to an increase in food intake, which increases the risk of obesity. Getting enough sleep can help reduce calorie intake and reduce the risk of obesity, according to a study published in the Journal of Internal Medicine of the American Medical Association.

Today, scientists are using atoms to measure the curvature of space-time.
In 1797, British scientist Henry Cavendish measured the strength of gravity with a torsion scale made of shot put, wooden stick and wire. In the 21st century, scientists are using more complex tools-atoms-to do very similar things.

Virus New HIV variants with high virulence found in Europe Human immunodeficiency virus (HIV) is one of the fastest mutating viruses known. Scientists have discovered a new strain of HIV in Europe, according to a new study in Science. This strain belongs to subtype B of HIV- 1, which is more virulent and contagious than other subtype B strains, and the disease occurs faster after infection, but the existing drugs are still effective.
