Stellar corpse reveals the origin of radioactive molecules

Astronomers with ALMA and NOEMA have carried out the first definitive detection of a radioactive molecule in interstellar space. The radioactive part of the molecule is an aluminum isotope. The observations show that the isotope was scattered into space after the collision of two stars leaving behind what is known as the CK vulpeculae. This is the first time that …

Carbon dioxide leak may have led to the rise of human civilization

The world's southernmost ocean emitted carbon dioxide into the air, resulting in an increase in CO2 that produced warmer climates. This, according to researchers, led to the emergence of human civilizations. ( Martin Fuchs ) A leak in the biological pump could have resulted in atmospheric carbon dioxide levels rising thousands of years ago, resulting in a warm, human civilization-friendly …

Bacteria start at rates much higher than scientists expect

According to new research, bacteria go much faster than scientists had ever expected. Between 45,000 and 95,000 bacterial species disappeared in the past millions of years – contrary to the widespread theory that they rarely die, she found. But despite the large numbers, bacteria remain resistant to mass extinctions that have hit larger organisms such as dinosaurs, researchers found. Scientists …

Currently it looks like Homo – a group of hominins that includes ancient beings such as Homo erectus and Homo neanderthalensis – is a family of seven, though that number is questionable. Regardless, Homo sapiens are the only …

NASA says Red Planet can not be terraformed soon

For years, scientists who wanted to colonize Mars have proposed the idea of ​​terraforming, where extensive groundwork on the red planet releases carbon dioxide into its surface and heats the planet sufficiently to pick up liquid water and make the conditions suitable The idea has also led SpaceX to send BFRs and make the Red Planet hospitable, but only recently …
