Ten animals that are considered extinct and reappear
A large number of animals are listed as endangered each year, and a significant number of them end up being listed as extinct. But there are quite a few of the top ten animals that are considered extinct and emerged again. They are the New Dutch Rat, the Short-winged Waterhen, the Pygmy Spectacles Monkey, the Laotian Rock Rat, the Four-lined Stone cipher, the New Caledonia Giant Gecko, the Prairie Western Reliever, the Tooth-billed Woodpecker, the Kangaroo Wolf, and the Honshu Wolf.

What is underneath the quicksand?
Everyone should have heard or read stories about quicksand, because quicksand is very popular in traditional cultures around the world, and it is believed that in the 1960s, one out of every 35 movies would be related to quicksand.

ESG and Sustainability will Continue to Gather Momentum and Attract Billions of Dollars in Investments
Momentum is building around ESG. Policy makers, asset managers and business are now more willing to integrate ESG and sustainability thinking in their investment strategies. Furthermore, President Biden has successfully approved a half a trillion Climate Bill creating positive momentum on ESG actions and climate risk reduction.

What happened to the probes that crashed into the moon but took life with them?
It is the moon's satellite and the most thoroughly studied exoplanet. We have launched many lunar probes in the hope of gaining a deeper understanding of the Moon. In the last century, in particular, the United States and the Soviet Union launched many probes, but none were very successful, so many crashed on the Moon or exploded in space.

Won't it get hotter in the future? What effect will the Earth's gradual move away from the Sun have on temperatures?
Because of the presence of the sun, the earth is guaranteed enough heat to maintain the temperature of the surface. Temperature is one of the most important conditions for the birth of living things. In other words, without the sun, there would be no Earth with its diverse biological populations.

Lunar eclipse photos, look at them and you will know how small we are
The Earth is the third farthest Earth-like planet from the Sun and is also the common home of countless creatures, including us humans, its radius is close to 6400 km, for humans or other creatures, the Earth is a behemoth, standing on the ground can not see the end at all, so in ancient times there are people who believe that the Earth is flat, and even that the Earth is the center of the universe.

I asked my cousin who Lu pin was and he said he was support. Can't do without a good science lesson!
The other day when I went to a relative's house, my younger cousin was playing King's Glory, using Lu pin 7. When he saw me coming, he couldn't wait to show off his record to me. He was playing an average game and had lost himself in the game. It's a bit of a bummer to see him so addicted to the game when he's only in 6th grade, but there's nothing I can do about it.

NASA spacesuit leaks again, how dangerous is it? There have been astronauts who nearly drowned
In our impression, the United States seems to spend money "big", to complete the Apollo manned lunar landing program, almost all the country's efforts, huge human, material, and financial resources, and finally, in 1969 the first manned lunar landing was completed. After the manned lunar landing program, the United States also manufactured a reusable space shuttle. It seems that the financial strength of the United States, but sometimes also to repair, a device with decades, for example, the United States is now using the spacesuit has been more than 40 years.

Revealing the genesis of the eastern margin of the Tibetan Plateau
As the "roof of the world", the formation and evolution of the Qinghai-Tibet Plateau, especially the internal crustal deformation, thickening and uplift, and outward expansion, are the main focus of research in the field of earth sciences. For the special geological phenomena on the eastern edge of the Tibetan Plateau, such as large-scale slip faulting, significant crustal thickening, and lack of Cenozoic crustal shortening, three classical geological models have been proposed, namely, rigid block extrusion, continuous lithosphere-scale deformation, and large-scale middle and lower crustal flow. Among them, the large-scale (>1000 km) middle and lower crustal flow has received wide attention and support from many scholars in the last 20 years. This model suggests that the crustal thickening at the eastern margin of the Tibetan Plateau is caused by the eastward flow of crustal material from the interior of the Tibetan Plateau (the North Tangential Massif) at a depth of 25-40 km to join the eastern margin of the Tibetan Plateau. Geophysical observations show that there is an extensive low-velocity, a high-conductivity layer at the eastern margin and interior of the Tibetan Plateau that supports the flow of middle and lower crustal material that can occur. However, some scholars have questioned this, arguing that the model lacks geological evidence and that some recent findings do not seem to support the existence of such large-scale crustal flows.

One third of the Earth is made up of liquid water
To gain a deeper understanding of the universe and find a future second home for humanity, scientists have been exploring a wide variety of celestial bodies, using ground-based and space-based equipment such as the Hubble Telescope and the Chinese FAST eye to make discoveries.

A most mysterious place, but also a place you can never know, at the same time!
Einstein's general theory of relativity is like a magnificent palace that looks imposing. He summarized the universal laws of the universe with only a few simple assumptions. For example, the bending of light has been measured and is almost identical to the calculations given by general relativity. The cosmic microwave background radiation also verifies the Big Bang. With the intervention of the cosmological constant, the accelerated expansion of the universe has also been rationalized. Einstein's theory of relativity has a nearly perfect explanation for the macroscopic universe. But as we mentioned earlier, general relativity explains the general laws of the universe, but the universe is not only general, it has many dualities. Today, let's talk about the ultimate mystery that haunted Einstein's like - black holes.
