“This water is much deeper than ever found before, at a third of the way to the edge of Earth’s core”
“If it wasn’t down there, we would all be submerged,” says Steve Jacobsen at Northwestern University in Evanston, Illinois. Northwestern geophysicist Steve Jacobsen and his team made the discovery. “This implies a bigger reservoir of water on the planet than previously thought.” Scientists have found deep pockets of magma located about 400 miles beneath North America, a likely signature of the presence of water at these depths. It looks like water from the Earth’s surface can be driven to such great depths by plate tectonics, eventually causing partial melting of the rocks found deep in the mantle.
“Geological processes on the Earth’s surface, such as earthquakes or erupting volcanoes, are an expression of what is going on inside the Earth, out of our sight,” said Jacobsen. “I think we are finally seeing evidence for a whole-Earth water cycle, which may help explain the vast amount of liquid water on the surface of our habitable planet. Scientists have been looking for this missing deep water for decades.”

“Some have argued that it’s only a matter of time till we find alien life – so we should get planning” writes Duncan Forgan in his article titled “What to do you if you discover an alien civilization” published in The Independent.
Indeed, what should we do?
In 1989, a committee of SETI scientists even drew up a set of post-detection protocols to guide scientists through the steps after discovery. These steps include getting your colleagues to verify the discovery, and notifying “relevant national authorities” (precisely who this means is unclear to me), followed by the scientific community and then the public via a press release.
However all these rules were formulated before the era of total internet communications. That is why Duncan Forgan and his colleague Alexander Scholz decided to take another look at the issue, asking how the SETI post-detection protocols should change to reflect our super-connected world.
Duncan Forgan’s postdoctoral position at the University of St Andrews is funded by the European Research Council. He is a member of the Royal Society of Edinburgh’s Young Academy of Scotland, and a founding member of the UK SETI Research Network.
No doubt, the game industry of today isn’t exactly the same as it was. Gaming industry statistics shows its steady growth trough years. Actually this fact is extraordinary, really, when you think about it.
On the other hand, no wonder that in the era of greatest engineering achievements we have so impressive impact of video gaming on the entertainment industry of course. Gaming sector is highly involved into one and we see the fast evolution of video games especially in terms of its graphical quality.
Gaming industry statistics shows very interesting facts about gamer skills, habits and demographics around the world. The average age of a gamer is 30-35 years old. Over three-fourths of all gamers play for more than one hour each week.
Examining the stats it’s easy to see new and new generation of gamers and how they make gaming a part of their daily lives. Sure, gaming has its ups and downs, but whether you are winning or loosing you don’t lose motivation and the goal you want to achieve.
Today gaming players are looking for where they can spend their leisure time playing online their favorite games. The online gaming industry has been expended around for a number of years and today the gaming online process have become easy enough.
Besides, more and more games become free today that gives any player additional happy opportunities. You can choose to play any games you love among growing number of video games for fun or set up an account for real play like all slots mobile that offers the best online slots you can choose from.
What to expect in the future? Probably more spectator experiences, more incorporated game’s tools, virtual reality headsets, mainstream vide games which become services and platforms and more. Be sure, you will not be bored with.
NASA researchers are working on a laser propulsion system that could get to Mars in 3 days Sciencealert reports. NASA scientist Philip Lubin is working on a system allowing to get the Red Planet in as little as three days. “There are recent advances that take this from science fiction to science reality,” Lubin explains. “There is no known reason why we can not do this.”
“Electromagnetic acceleration is only limited by the speed of light while chemical systems are limited to the energy of chemical processes,” writes Lubin in a paper on the technology.
Reportedly that the rate of sea level rise may increase even faster than scientists could expect. Actually there are many causes why that can happen. But one of them is the melting of the West Antarctic Ice Sheet. The ice sheet is accounted as an “unstoppable” yet. In the U.S. alone, nearly 30,000 square miles of land – home to 12.3 million people today – lies less than 10 feet under the high-tide line, including more than half the area of 40 large U.S. cities like New York City, Boston and New Orleans. Roughly one third of the U.S. population lives on low-lying land that is vulnerable to consequences of varying severity, from permanent inundation to saltwater intrusion into freshwater sources. Unless adaptation measures are taken, sea level rise could cost the globe $1 trillion annually by 2050.
A new study finds that climate change may affect the Greenland ice sheet more seriously than scientists could imagine.
The new study , published Monday in the journal Nature Climate Change, focuses on a part of the ice sheet known as “firn” – a porous layer of built-up snow that slowly freezes into ice over time. It’s considered an important part of the ice sheet because of its ability to trap and store excess water before it’s able to run off the surface of the glacier, an essential service that helps mitigate the sea-level rise that would otherwise be caused by the runoff water.
“As this layer is porous and the pores are connected, theoretically all the pore space in this firn layer can be used to store meltwater percolating into the firn whenever melt occurs at the surface,” said the new paper’s lead author, Horst Machguth of the Geological Survey of Denmark and Greenland , in an email to The Washington Post. Over time, the percolating meltwater trickles down through the firn and refreezes.

Atmospheric carbon dioxide (CO2) levels climbed above the 400 parts per million (ppm) and it’s distinctly possible they won’t be back below that level again in our lifetimes.
“As a human, though, passing both the 400 ppm and (potentially) the 1°C threshold within such a short time period makes it clear we are already living in a different world. We have blown past targets that were being considered as viable when I entered graduate school. We have significantly reduced the options available to us in the future. If we aren’t going to blow past the next set of thresholds — 500 ppm and 2°C — within just a few more decades, we have a lot of work to do in Paris in two weeks and beyond.” Katharine Hayhoe, atmospheric scientist at Texas Tech University.
Scientists have unraveled part of the genetic code of a child who was sacrificed in a ritual ceremony by the Inca civilisation 500 years ago. The Inca boy had been ritually killed some 500 years ago. His body is naturally mummified in the cold, dry environment of the Aconcagua Mountain.
The scientists extracted an uncontaminated sample from the boy’s lung tissue, and found that he belonged to an unknown subgroup of the diverse genetic lineage called C1b, which dates back to the earliest Paleoinidans more than 18,000 years ago. According to a report in Science, the team labeled this unidentified subgroup C1bi, which is thought to have originated in the Andes some 14,000 years ago.
A check of genetic databases revealed four other known individuals in the C1bi group: three samples came from modern-day people living in Peru and Bolivia. The fourth sample came from the ancient Wari Empire, which predated the Inca in Peru. Population geneticist Andrés Moreno-Estrada of Mexico’s National Laboratory of Genomics for Biodiversity suggests that the two ancient samples indicate that the now-rare genetic variation was common before the arrival of Europeans.
