Although it is known that chronic stress can lead to depression, the mechanisms that regulate this relationship are not entirely clear. Now, new research published in the journal PNAS has identified a protein that has a lot to say in this process.
Eleven of the thirteen Neanderthals that inhabited the El Sidrón cave (Asturias) were right-handed. This is one of the results of a study by the Higher Council for Scientific Research (CSIC) in which the stretch marks of more than 60 teeth of this hominid species have been analyzed. The work, published in PLOS ONE, shows, along with other anatomical and functional evidence of brain lateralization, that Neanderthals had a pattern of brain asymmetry similar to that of modern humans.
Mimicking the complicated eye of a fly, a team of American scientists has created a hemispherical digital camera with 180 tiny microlenses that produces images with a very wide angle of view (180 degrees) and unprecedented definition. "What we have are many small eyes in one big eye," explains Yonggang Huang, co-author of the work.
A recent study carried out by economists from the University of Colorado in Denver (USA) revealed that looking for work online reduces the time we remain unemployed by up to 25%, especially if you take advantage of the contacts (friends and family) that you have online .
Between 30,000 and 50,000 years ago, the landscape of Gibraltar and the Doñana National Park was not very different from the one we observe today, according to a study by the University of Huelva in which the species of plants and animals that inhabited have been identified. in a series of caves in the area.
Scientists from the CERN ALPHA collaboration have presented the first direct evidence of how antimatter atoms interact with gravity. The study, published by Nature Communications, has focused on measuring the gravitational mass of antihydrogen, the simplest neutral antimatter atom.
Scientists at Princeton University (USA) have used a three-dimensional printer loaded with cells and silver nanoparticles to create a bionic ear in which cartilage is combined with an antenna that captures the same sound frequencies as a meat ear and bone. The team, led by engineer Michael McAlpine, has been the first to create a fully functional organ that reproduces and even extends the capabilities of its human counterpart, as explained in NanoLetters magazine.
Researchers from the University of Granada have developed a new computer system that allows predicting what sales a book will have if it is published, very useful information for publishers, which could thus decide the print run of a work. This new tool, called PreTEL, is based on artificial neural networks, and also allows launch and run simulations from a statistical point of view, which can help decide whether a book is publishable or not.
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.
