One of the most destructive forces on the planet, a supervolcano eruption is as deadly as it is unpredictable. While it isn’t too hard to determine that a supervolcano is forming at a location, knowing whether it will erupt in 1 year or in 100,000 years remains a challenge.Now scientists at the European Synchrotron Radiation Facility in Grenoble believe that they’ve discovered the secret to what it is that sparks a supervolcano to erupt. Surprisingly, it appears that the sheer volume of magma alone is enough to trigger an eruption.”We knew the clock was ticking but we didn’t know how fast: what would it take to trigger a super-eruption” said guide author Wim Malfait. “Now we know you don’t need any extra factor – a supervolcano can erupt due to its gigantic size alone. Once you acquire enough melt, you can start an eruption just like that.”

Feathers were uncommon among dinosaurs

The discovery of feather imprints on dinosaur fossils has guide to a lot of speculation over just how many of these prehistoric reptiles would have been adorned with a bird-like plumage. Some scientists believe that most of the dinosaurs would have had them, while others are not so sure.eager to receive to the bottom of this mystery, palaeontologists Paul Barrett David Evans set up a database covering all known discoveries of dinosaur skin imprints. By identifying those with feathers and analyzing the relationships between different species, they were able to ascertain that only a little number of dinosaurs were likely to have had them.”Id go so far as to say that all dinosaurs had some sort of genetic trait that made it easy for their skin to sprout filaments, quills and even feathers,” said Barrett. “But with scales so common throughout the family tree, they nevertheless look like they are the ancestral condition.”

What does the Earth’s movement sound like ?

How do you record the sounds of the Earth Image Credit: NASA Artist Lotte Geeven has recorded audio of our planet from the bottom of the deepest hole in the world. Despite spending all of our lives on the surface of the Earth, one thing we never acquire to listen is what our planet’s rotation and movement through space actually sounds like.To tackle this problem, Geeven and a production team ventured deep in to the bowels of the Earth via the deepest open hole anywhere on the planet, a place located on the border of the Czech Republic.At a distance of 5.5 miles underground, the team used special equipment to record the very sounds of the Earth itself.The recording can be heard under.

The company, named Leia Display Systems after the Star Wars heroine who famously appeared to Obi-Wan Kenobi in a holographic projection, is aiming to make their groundbreaking hologram communication device available to consumers within five years.”Our holograms will take video phone calls to the next level,” said chief executive Marcin Panek. “We are on the frontier of technology that was imagined in movies 40 years ago – it is science fiction becoming science fact.”The system will use a special camera on one end to record the video and a hologram generator on the other end that uses water vapor to manufacture a three-dimensional image.”At the moment, our holograms are made using machines that are more than six feet high but we are designing smaller versions that can be set up on a coffee table in a living room,” said Panek.
