Humans are not alone? Expert: There may be at least 36 "alien civilizations" in the Milky Way
Since humans began to explore outer space, there have been more and more conjectures about outer space. For human beings, the universe is vast, so on the way to explore the universe, human beings still have a long way to go.

Jupiter is a gaseous planet, so can we pass through Jupiter as we pass through the air?
If we take a spacecraft to Jupiter, we will find that we can't find a place to land at all, so many friends have thought of a question, isn't Jupiter a big balloon? It’s not enough to drive this spaceship directly through it. You must know that the air on the earth can’t be seen or touched. We can come and go freely in the air and do all kinds of free activities. And Jupiter is a gas planet, that's true, but it's impossible for us to pass through Jupiter as we pass through air, why would I say that?

The real "guardian" of mankind, if it weren't for him on duty 38 years ago, civilization may have disappeared
Since the birth of nuclear weapons, mankind has known that it is very simple to destroy civilization. Just a 20,000-ton atomic bomb can raze Hiroshima to the ground. What if it reaches 100,000 tons? What will be the consequences? And even after the explosion, radiation will continue to harm living things and the environment. After being attacked by radiation, there will be serious physical changes, or diseases, and death is an inescapable fact.

Small cells make a big difference: stem cell therapy for stroke
"Cerebral stroke", also known as "stroke" or "cerebrovascular accident", is an acute cerebrovascular disease, which is caused by sudden rupture of blood vessels in the brain or the inability of blood to flow into the brain due to vascular blockage. A group of diseases, divided into ischemic and hemorrhagic stroke. The incidence of ischemic stroke is higher than that of hemorrhagic stroke, accounting for 60% to 70% of the total number of strokes. Occlusion and stenosis of the internal carotid artery and vertebral artery can cause ischemic stroke, and most people are over 40 years old, more men than women, and severe cases can lead to death. Hemorrhagic stroke has a higher mortality rate. Stroke has the characteristics of high morbidity, high mortality and high disability rate.

At 11:20, the Long March 6 carrier rocket was successfully launched, sending 9 satellites into space at the same time
What everyone is most concerned about in the past two days is the launch of our Tianhe core module. The official choice has not yet been clearly stated at which time of the two days, but it is obviously long-awaited for the Chinese people. After all, the launch of the core module and the The launch of the cargo spacecraft in May and the launch of the manned spacecraft in June will be docked in the future space battle, and our 3 astronauts will enter the space station in the future, and they will stay for at least 4 to 5 months, which is It is unprecedented, so for the Chinese people, this year's China Aerospace is destined to be an extraordinary year! Of course, whether it is the launch of the core module, the launch of a cargo spacecraft or the launch of a manned spacecraft, it all depends on the launch vehicle, and we obviously have to rely on the Long March series of rockets to complete it! And when we are all looking forward to the launch of the core module, we saw that the Russian carrier rocket completed the feat of 36 stars on the 26th, which is really admirable!

Have humans really succeeded in domesticating cats? Don't get too excited, the cat may just want a lap
There is a saying to describe the difference between cats and dogs: if you provide dogs with food, shelter, and protect them every day, then in the eyes of dogs, you must be God, otherwise how can you be so good to yourself.

Electric eel: Known as "high-voltage line in water", it electrocuted several piranhas at once
If you want to gain a firm foothold in the fierce competition in the biological chain market, each microorganism must continuously adjust itself in the whole process of adapting to the new environment. Many animals have evolved their own supernatural abilities in order to better capture food ingredients. And then to the "top".
