American researchers have described the oldest dinosaur fossils. The remains of the new Nyasasaurus parringtoni date from the Middle Triassic, and are estimated to be 10 to 15 million years older than any other known dinosaur remnant. "If it is not the first dinosaur, at least it is the closest relative to it that we have found," explains Sterling Nesbitt.
Children who are at risk of social exclusion and are taken in by homosexual parents experience the same increase in cognitive development and IQ as those taken in by heterosexual couples, according to a study published in the American Journal of Orthopsychiatry.
Smartphones are increasingly so. They guide you and help you find streets when you are lost, they give you the weather forecast and inform you of the nearest ATM. And, in the future, they might even tell you what mood you're in and put on music that suits your mood. It is not fiction: a team of researchers from the University of Rochester (USA) is already working on an application that detects how a person feels just by listening to their voice.
After the enigmatic announcement of John Grotzinger, principal investigator of the Curiosity mission, in which he spoke of promising results of the robot that explores Mars, the illusions were deflated in the press conference offered yesterday at the annual meeting of the American Geophysical Society. The Curiosity robot has not found life or traces of it on the neighboring planet, although its first soil analysis has detected very simple compounds that contain carbon. These are very small samples consisting of a carbon atom with one, two, or three chlorine atoms attached to it.
The huge hole that cuts through the Arizona region has long been the subject of debate among the scientific community. Until now, estimates of the age of this natural giant, mostly based on the dating of the sediments that form it, varied between 5 and 17 million years. However, new research analyzing the distribution of helium atoms in rocks indicates that the Grand Canyon began to form much earlier, no less than 70 million years ago.
When two guitarists play together, their brains are perfectly coordinated, and as a result of this perfect synchronization, beautiful pieces of music are obtained. A team of scientists from the Max Planck Institute for Human Development (Berlin) has decided to investigate the brains of musicians and analyze their activity when they form duets. The results reveal many similarities in the electric wave dance that occurs in the heads of these artists when they coordinate to play, and these similarities hold even when the musicians perform different voices from the piece.
Wisdom teeth, also called 'third molars', are almost always a hindrance: in many cases they have to be extracted and it is rare for the person who does not suffer discomfort when these late teeth begin to appear. However, an investigation carried out by researchers from the International University of Catalonia has just shown that wisdom teeth are not so useless, since they contain populations of stem cells from which different tissues such as bone, liver can be regenerated and the neuronal.
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.
