The behavior of mountain Neanderthals is still largely unknown to the scientific community, at least within European limits. Different studies have shown that the species used animal bones as fuel for the bonfires that they lit, especially when the tree mass was scarce.
A team of astronomers has combined new observations of Gliese 667C with data from the HARPS instrument, installed on ESO's 3.6-meter telescope in Chile, to reveal the existence of a system with at least six planets. But what breaks all records is the fact that three of these planets are super-earths located in the area surrounding the star within which there could be liquid water, making them possible candidates for the presence of life.
Differences between Martian meteorites and rocks examined by NASA's Spirit rover suggest that Mars had an oxygen-rich atmosphere 4 billion years ago, that is, long before oxygen appeared in Earth's atmosphere 2,500 years ago. millions of years.
The vegetables that we buy daily are still alive since, even after harvest, they respond to light signals and, therefore, change their biology, improving their resistance to insects and their nutritional values. This is what researchers from Rice University (USA) have shown who, in the latest issue of the journal 'Current Biology', suggest that the way in which products are stored and when they are consumed could have consequences on the Human health.
At the end of their life, after having divided fifty or more times, our cells often rest and "retire." They enter a state known as senescence in which they are still active but cannot duplicate more, and which is associated with aging and cancer prevention. Now, research in which the Center for Genomic Regulation (CRG) has participated reveals a new detail: by secreting a cocktail of factors, senescent cells can transmit their "retirement" state to other nearby cells.
A study by mathematicians from the University of Uppsala (Sweden) reveals that applause is contagious behavior and that, when we attend a concert, a conference or a play, individuals feel more pressure at the end to join the group. applause the greater the number of spectators clapping their hands.
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.
