Not asteroids, not dark matter, not any other explanation. The greatest mass extinction of our planet of about 252 million years ago and that wiped out 90% of all species, could be caused by a tiny but controversial culprit: a microbe. This is the conclusion of a team of researchers from the Massachusetts Institute of Technology (MIT) whose study has been published in the journal Proceedings of the National Academy of Sciences.
Until April 15, all Internet users are invited to vote for one of the three Z-2 spacesuit prototypes jointly conceived by NASA, the ILC Dover company and design students from the University of Philadelphia.
This discovery made by a team of NASA scientists is due to the long periods of microgravity to which astronauts traveling into space are subjected. This change in the anatomy of the heart could lead to cosmonauts suffering from heart problems.
A group of researchers from the University of Missouri (USA) has completed the genetic history of 134 breeds of cattle from around the world. In the process they have discovered that the oldest domesticated variety in Africa is native to the Middle East.
In the world of science to say that something will never happen is almost a good joke, thankfully. Now, a nanoparticle has defied the laws of thermodynamics, specifically the second, by being able to transfer heat to an even hotter gas. The results of the work have been published in the journal Nature Nanotechnology.
According to John McGlone of Texas Tech University in Lubbock, he discovered it by chance. He was researching the qualities of androstenone and his dog wouldn't stop barking. So he decided to spray it on it to see what would happen.
Some ancient marine animals filtered the food they took directly from the ocean, more or less as certain cetaceans do today. That's at least what fossils found in northern Greenladia suggest. A study promoted by researchers at the University of Bristol, in the United Kingdom, and published in Nature establishes that archaic arthropods of the species Tamisiocaris, which lived about 520 million years ago, were nourished thanks to a mechanism similar to that which still exists today. Baleen whales use.
NASA's Wide Field Infrared Explorer, the WISE telescope, has made it possible to locate what appears to be the cosmic seed from which a black hole will later sprout, that finite portion of space within which there is such a high concentration of mass that none material particle, not even light, can escape from it.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
