1. Break through the low temperature limit.
In the past, there was a scientific consensus that there was no way to cool an object below the "quantum limit". To get low temperatures, physicists use lasers to reduce the speed of atoms and thus reduce their thermal vibrations. But the laser itself also brings more energy to the atom itself, so it is difficult to obtain a temperature below the quantum limit.
Recently, however, physicists have devised a vibrating foil drum that lowers its temperature to 360 micro-Kelvin, which is more than 10,000 times lower than the lowest temperature in the depths of space. This experiment pushes the limits of low temperatures.
2. The brightest light.
Sunlight is already dazzling, but imagine what it would be like if there were a billion suns as bright, but physicists have done it recently. They created the brightest light on earth in the lab, and the behavior of Guan was quite amazing, he was able to change the appearance of objects.
3. Molecular black holes.
Recently, a physics research group created something that behaves very similarly to a black hole. They use the most powerful X-ray lasers (linear accelerator continuous light source LCLS) to bombard methane iodine and methane benzene.
When bombarded with a normal laser, the light source removes the electrons from the outside of the iodine atoms. But when LCLS is used to bombard, in addition to removing this effect, something magical happens, the iodine atoms start to suck electrons from adjacent hydrogen and carbon atoms, as if they were forming a small black hole inside the molecule.
4. Metallic hydrogen.
Metallic hydrogen has been called the "holy grail" of the high-pressure physics community. But it is only recently that scientists have succeeded in creating metallic hydrogen. In 1935, it was proposed that hydrogen be a very good superconductor after it was turned into a metal.
Theoretically, hydrogen can complete this phase transition as long as sufficient pressure is supplied. But there was no way to generate such tremendous pressure before, and it was only recently that an American group achieved this tremendous pressure (more than 10 million pounds of square inches) in various ways, and such a tremendous pressure could not be achieved even deep in the heart of the earth.
5. Photonic computing chips.
For the electronics industry, photons will replace electrons sooner or later. The traditional electronics industry relies on transistor switches to complete calculations, but there is an upper limit to this. Recently, scientists have created a chip that uses photons to make calculations, using the connections between light beams to do calculations, just as the brain uses neurons.

2.There are always various "science" circulating in the circle of friends, drinking tea today can make people live longer, and drinking tea tomorrow may lead to nervous breakdowns. Recently, the journal Nature has also taken it a long time to publish five "scientific myths" that should have disappeared long ago but are still widely circulating.
They look scientific, but they are actually fallacies.
Kiss, this is a relevant addition.

Although I don't know what it is, I thought of a very good movie, rejuvenation. There is a disease of a boy that grows in reverse, he is an old man at birth, and then he grows younger and younger, and when he dies, he becomes a child, and the lover keeps getting old. Recommend.
