Did you know that scientists have invented a whole new state of matter called time crystals? Or that the adorable faces of pugs are the result of a genetic mutation?
Here are some of the impressive scientific facts we learned in 2017:
1. A human organ that no one knew has been hiding in plain sight all this time. Called mesentery, it connects the intestine to the abdomen and is believed to perform important functions for the body, ranging from helping the heart to helping the immune system.
2. Earth appears to have a whole new underground continent called Zelandia. The discovery itself is not new – some geologists have argued for its existence for many years. However, in 2017, a team of scientists concluded that Zealandia met all the requirements to be considered a drowned continent.
3. The cute little flat faces of pugs are the result of a genetic mutation. Their characteristics have been strongly linked to a genetic variant called SMOC2.
4. For the first time in human history, gene editing has been performed to correct a mutation of an inherited disease in embryos. Using a powerful tool called Crispr-Cas9, scientists have succeeded in altering the DNA of defective embryos so that they are no longer programmed to develop congenital heart failure.
5. Your Annex may not be a useless organ after all. Research suggests that it may play a role in the immune system as a secondary defensive organ, acting as a “safe home” for helpful gut bacteria.
6. Giant penguins about the size of an adult man who waddled around New Zealand about 59 million years ago.
7. The smallest in the world spinning top is 100 microns wide. It is smaller than the width of a human hair and is barely visible to the naked eye.
8. The lungs do more than help us breathe – a surprising finding has revealed that they do too some blood. It is believed that the organ, found in mammals, produces more than 10 million platelets (small blood cells) per hour.
9. A new state of matter exists (alongside solid, liquid and gas) and it is known as time crystals. Created in the laboratory, the extremely hard-to-grasp time crystals are structures that repeat themselves periodically in time rather than in space, potentially defying the laws of physics.
10. Great apes, including chimpanzees and orangutans, absolutely dislike music anything. Research has shown that they cannot tell the difference between Beethoven and Bieber, and music is just meaningless sound to them.
11. The dinosaur the family tree may need to be redesigned for the first time in 130 years. New evidence has revealed that the two categories of dinosaurs – lizard-hip meat eaters (like T. Rex) and plant-loving bird-hip beasts (like Stegosaurus) – should actually be lumped together. , making you question everything you’ve ever learned. about these animals that disappeared from school.
12. Humans have accidentally created a protective bubble around the Earth. Decades of use of very low frequency radio communications (VLF) have resulted in an artificial cocoon that could help protect the planet from solar flares and radiation particles.
13. Precious metals on earth, like gold and platinum, can come from the stars. Scientists confirmed this after detecting a titanic collision of two super dense neutron stars 130 million light years from Earth.
14. The Kepler-90 star system has as many planets as our own solar system, making us on par with the largest number of planets revolving around a single star known to date. By combining data from the Kepler Space Telescope with Google’s artificial intelligence system, NASA discovered an eighth planet – called Kepler-90i – which astronomers missed in their previous analysis.
15. Pandas are black and white because their patterns are a combination of communication and camouflage, according to a study published in Behavioral ecology.
16. The moon once had a atmosphere. Recent tests of lunar samples collected by Apollo astronauts reveal that volcanic eruptions that occurred around four billion years ago released billions of tons of gas. As gases were produced faster than they could escape into space, an atmosphere formed. The gases eventually got lost in space.
17. Scientists could finally find out why eggs come in different forms, and apparently everything is due to the bird’s ability to fly. It seems that the best fliers are those that lay more “pointed” or elliptical shaped eggs, while the others are more likely to lay rounded or oval shaped eggs.
18. It is theoretically possible to go back and forth in time. Two physicists developed a mathematical model for a time Machine based on Einstein’s theory of relativity (which was proven in 2015), that gravitational fields are caused by distortions in the structure of space and time. What holds us back is that the technology that can physically fold this space-time fabric has yet to be invented.
19. Harvard scientists have stored a Animated gifs of a galloping horse in the DNA of bacteria, using the Crispr-Cas9 tool.
20. Bees have been shown to understand the concept of zero. Scientists discovered it after training insects to count shapes, following previous research that found they could count to four.
21. Humans are still evolving. Researchers who have tracked eight million mutations have found that a number of genes – like the one that predisposes you to Alzheimer’s disease – are gradually filtered out of human DNA.
22. There are aliens dust particles on your roof. They are called micrometeorites and measure around 400 microns. More than 100 billion micrometeorites are said to fall on Earth each year.
