Researchers at the Instituto de Astrofísica de Canarias (IAC) have found evidence that the presence of "carbon onions" and other large molecules derived from fullerenes (a form of carbon) could be widespread in space. These are the most complex molecules observed so far, and their finding has important implications for understanding circumstellar and interstellar physico-chemistry, as well as molecular processes in the later stages of the evolution of stars.
A Danish study based on a storm that fell in May 2009 reveals that rain-laden clouds are also teeming with bacteria and chemicals, specifically up to 3,000 different compounds commonly found in the ground.
For centuries, sailors and travelers have oriented themselves thanks to the stars and it is known that many birds also use this night map to make their movements. Now, a group of scientists from the University of Lund (Sweden), has discovered another animal that looks to the sky to orient itself: the African dung beetle.
Each person is able to recognize their own scent thanks to the major histocompatibility complex (MHC), a unique combination of proteins similar to that used by animals to recognize their partners. These are the results of a study published in the journal Proceedings of the Royal Society B, the first to show that humans do indeed 'smell' ourselves.
After comparing the genome of domestic dogs with that of wolves, from whom it is probable that they were evolutionarily separated 10,000 years ago somewhere in Asia, a team of researchers from the University of Uppsala (Sweden) has discovered that the domestication of the dog It has to do with an evolution of his digestive system that allowed him to eat a diet rich in starch, more similar to that of humans.
The US National Institutes of Health (NIH) have reported that in the future hardly any chimpanzees will be used for biomedical research, considering that their use is "not necessary" in most cases, thus accepting the recommendations of the Institute of Medicine ( IOM). In fact, they have announced that they will not fund any new research projects using chimpanzees.
Owl monkeys that have a stable partner and are faithful to it reproduce more than those with multiple partners, according to a study by the University of Pennsylvania (United States), published in 'Plos One'. The work reveals how monogamy and mating, relatively rare among mammals, can benefit hundreds of individuals. And it could help to understand how the patterns of relationships in human beings have evolved, as the anthropologist Eduardo Fernández-Duque and his colleagues point out.
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.
