What s the coldest piece of knowledge you know?

Lighthouse jellyfish (Turritopsis nutricula) Timeless beauty. Whenever the lighthouse jellyfish is dying, it returns to its juvenile polyp form, and the cycle repeats to infinity. So theoretically, as long as it is not harmed, it is immortal.

The lighthouse jellyfish is only 4 5 mm in diameter, but it is such a tiny creature that has a magical ability to "rejuvenate". According to reports, normally, jellyfish will die after reproducing the next generation, but after the "lighthouse jellyfish" reach the stage of sexual maturity, they will return to the young stage and start another life process, and theoretically, this cycle process is repeated again and again and can be repeated forever. "Lighthouse jellyfish" belongs to the class Hydrops, which is a predatory organism that mainly feeds on smaller microorganisms, adopts a vegetative reproduction mode, and mostly lives in tropical waters.

Scientists emphasize that the "lighthouse jellyfish" is the only creature found so far that is able to revert from the stage of sexual maturity to the larval stage. According to a scientist who has been working on lighthouse jellyfish for a long time, he observed about 4,000 lighthouse jellyfish, and the results showed that all of them were "rejuvenated" and did not die of their own causes. As for how the "lighthouse jellyfish" accomplishes the miraculous process of "rejuvenation", the mystery remains to be answered by marine biologists and geneticists.

Some researchers believe that the "rejuvenation" process of "lighthouse jellyfish" may be achieved through the process of cell transdifferentiation. During this process, the type and function of the cells change. And this functional transformation is accompanied by the regeneration of organs.

Perhaps it is this process of cell change that creates the immortality of the "lighthouse jellyfish". I can't see the vampire of eternal darkness, I can't see Odin sitting on the high throne of Valhalla, and I don't know that the Black Pearl has been opened.

But in the Caribbean, there are immortal elves. <>

The rain that goes up and down Saturn is diamonds. New research by Kevin Baines of the University of Wisconsin-Madison, a member of NASA's Jet Propulsion Laboratory, says up to 1,000 tons of diamonds are produced in Saturn's atmosphere each year. Under the action of Saturn's high temperature and pressure, the methane in the upper atmosphere will turn into carbon black (carbon), and as the carbon black decreases and the air pressure increases, it becomes graphite again.

After another 4,000 miles of descent, the pressure increased to the point that the graphite turned into diamond. If it continues to fall, those diamonds risk turning into a liquid ocean of diamonds. This is the newly discovered storm of the Cassini space probe on Saturn, nicknamed "The Rose of Saturn".

The exterior is as beautiful as a rose, but it contains a lot of diamond rain. If you love her, take her to Saturn. <>

The coldest knowledge is:1. The giraffe's tongue can lick deep into its own ears. Use it to clean your ears.

2. When the hippopotamus bathes in the sun, it will produce a kind of sunscreen for its own **.

3. Although the spider has eight legs, the spider has claws.

4. Toucans in the zoo need to drink tea. Caged toucans mostly suffer from diseases, especially those caused by too much iron due to low tannic acid intake. To prevent or ** iron overload this disease, zoo managers will make tea for toucans.

5. The sex of the crocodile is determined by the temperature, and when it is just born, it has no sex. Instead, during the incubation process, the sex is selected according to the ambient temperature. So, if you find a crocodile nest in the wild, you have to know that the crocodile nest is built on leaves, and where the temperature is high (close to 34 degrees), it is a litter of males.

The nest is built on a wet swamp and is a litter of females. Whether you want to eat male eggs or female eggs, you can choose.

It is produced by acting on receptor proteins on the nociceptive fibers in the tongue. This pathway is also a pathway for pain sensation. So, from a neuroscience point of view, spicy is more akin to pain.

When it comes to women, there is never enough to say. With the progress of society, women are playing an increasingly important role in society, and they are also facing a variety of doubts and health problems.

1.No sheet of paper can be folded in half more than 7 times.

2.According to statistics, donkey boys kill more people every year than in plane crashes3People burn more calories by sleeping than by sitting and watching TV.

4.The first type of item with a barcode is chewing gum.
