The supernova that we can see in the image exploded more than 9,000 million years ago and, thanks to the NASA / ESA Hubble Space Telescope, a team of astronomers from the University of California at Berkeley (USA) has been able to observe by first time in history, four different images of the explosion of this star.
Can a healthy brain be preserved for almost 3,000 years? That seems, after the confirmation by a team of archaeologists from the York Archaeological Trust (United Kingdom) that the brain found in 2009 in the town of Heslington (York, United Kingdom) belonged to a person and that it is around 2,600 years old. .
For quite some time (several decades), scientists have been trying to determine when and in what way the genus Homo, our lineage of men, differentiated itself to begin the complex evolutionary process that ended in the humans that we are today. Now, an international team of researchers has made a crucial discovery for the clarification of this issue that concerns us so much: a fossil of a hominid that is 2.8 million years old.
Much has been speculated about the handshake, a gesture documented in Egyptian hieroglyphics more than 5,000 years ago: that if it is a reliable clue to find out if your interlocutor is timid or has a firm character, that if it formerly served to make it clear that you weren't carrying weapons… Now, a study published in the eLife magazine, carried out by scientists from the Weizmann Institute (Israel), suggests that when we shake hands, we are actually collecting molecular samples of the scent that the other person emits.
According to quantum mechanics, light can behave both as a wave and as a particle. For example, when ultraviolet radiation reaches a metal surface, an emission of electrons occurs. For Albert Einstein, this "photoelectric effect" demonstrated that light was not only a wave, but also showed a nature of particles. Now, a team of researchers from the Federal Polytechnic School of Lausanne (EPFL), in Switzerland, coordinated by physicist Fabrizio Carbone, has managed to obtain for the first time a snapshot of light working at the same time in both ways.
Can Social Media Help Fight Youth Depression and Suicidal Feelings? Facebook believes so and that is why it has created a new mechanism to combat this current evil among users themselves.
An investigation by the Department of Vertebrate Paleontology at the Museum of Natural History in New York has discovered seven 13-million-year-old crocodile species in a fossil deposit in the Peruvian Amazon. Before the Amazon River developed as it is today, biodiversity was linked to swampy environments with an abundance of mollusks.
A team of scientists from the Max Planck Institute (Germany) has discovered a key gene for the evolution of the human cerebral cortex, which is nothing but the seat of the mind, since it is the area of the brain in charge of controlling emotions, language and conscious thought. This important gene that appeared after our evolutionary separation from chimpanzees but before Neanderthals, stars in the study published in the journal Science.
