How to effectively "manage" five bosses, Dr. MIT, talk about how to get along with mentors
. A collection of journals and services under Nature, dedicated to serving the scientific community, we provide a range of high-quality products and services covering life sciences, physics, chemistry and applied sciences. Among them, the journal Nature (Nature), founded in 1869, is a leading international science weekly.

Don't throw banana peels when eating bananas. It has a chance to make your car run.
After eating bananas, we always take it for granted to throw the banana peel into the dustbin. But there are always scientists who have to do something unusual, coupled with the fact that they have "high-end" devices, so they decide to take a look at what happens with only a xenon lamp. But before we talk about what these scientists do, we have to know why they have to put the banana peel in the oven and bake it.

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.

When he went to live in space for half a year, the astronaut's brain was squeezed and the circuit inside changed.
In space, due to the lack of force, even hair can fly in all directions. But why is the brain squeezed? Living on the earth, there is probably no kind of animal that is not subject to gravity.

More than a hundred years ago, Edward Charles Pickering, an astronomer at Harvard University in the United States, decided to "take" a picture of the entire night sky, or use thousands of pieces of debris recorded through a telescope to form a complete picture of the night sky. Today, these photos are sealed under thousands of glass negatives at the Harvard Observatory, the earliest detailed record of the universe. Although the idea for the all-sky map was originally put forward by Pickering, the daunting task was mainly accomplished by a group of women known as Harvard computers. Before the advent of computers made up of silicon chips and circuits, scientists in the fields of physics and astronomy used to rely on their hands to deal with complex computing tasks.

Can the microbes raised by plastic waste help us eat plastic garbage?
The problem of plastic pollution is becoming more and more serious. In addition to familiar measures such as reducing waste and recycling, scientists have also found a powerful ally for us-microbes. Some microbes have evolved the ability to "eat" some plastics, which may soon help us reduce plastic waste and build a greener circular economy.

Physiology A new way to lose weight: local hyperthermia activates beige fat Recently, researchers from the School of Life Sciences of East China normal University and the sixth people's Hospital affiliated to Shanghai Jiaotong University have found that beige fat (Beige fat) in human body can activate thermogenesis through local hyperthermia, reduce obesity symptoms and improve metabolic disorders. On March 4, the study was published as a cover article in the journal Cell.
