Our ability to reconstruct the likenesses of long-dead humans has made immeasurable progress in recent decades. With detailed computer programs, DNA studies, and advanced technologies like 3D printing — the margin of error in scientifically reconstructed faces is shrinking. The result is stunning lifelike portraits of ancient people who left this Earth thousands upon thousands of years ago. Facial reconstruction is a delicate mix of science and art.
You've got your headphones on, lost in a song, when a particularly powerful chorus or instrumental break sends tingling ripples down your arms and legs. Or maybe the hair on the back of your neck stands on end. It's a phenomenon that can occur during live or recorded music, new or known, and it's been well documented over the years. But one question persists: Why does it happen? Researchers have set out to find the answer, and a recent study published in Frontiers in Neuroscience focused on mapping out the brain's electrical activity during musical chills sheds further light on how music can activate the brain's pleasure and reward centers. Neuroscientists based in France used high-density electroencephalography HD-EEG to illustrate patterns of cerebral activity when people are subjected to pleasurable musical chills.
By Jonathan Chadwick For Mailonline. Australian researchers have analysed the radiocarbon record from ancient trees in New Zealand that were alive when the magnetic poles flipped. But preceding the flip was a weakening of the magnetic fields, causing electrical storms, crimson skies, widespread auroras and lethal cosmic radiation that frazzled our early ancestors and the Earth's wildlife. The researchers dubbed this danger period the 'Adams Transitional Geomagnetic Event', or 'Adams Event' for short — a tribute to science fiction writer Douglas Adams. The British author famously wrote in The Hitchhiker's Guide to the Galaxy that '42' was the answer to life, the universe, and everything.
Early European modern humans EEMH or Cro-Magnons were the first early modern humans Homo sapiens to settle in Europe, continuously occupying the continent possibly from as early as 48, years ago, with intermittent presence since at latest , years ago. They interacted and interbred with the indigenous Neanderthals H. EEMH produced Upper Palaeolithic cultures, the first major one being the Aurignacian , which was succeeded by the Gravettian by 30, years ago.
