    FULL TITLE: Is California about to be hit by the 'Big One'? Fears of a massive earthquake rise after 134 mini-tremors rattle the San Andreas fault in just one week Fresh fears have been raised that a huge earthquake is about to hit California after a swarm of recent tremors. In the last week 134 earthquakes have hammered a three-mile stretch around Monterey County on the San Andreas fault. Of those earthquakes, 17 were stronger than 2.5 magnitude and six of them were stronger than 3.0, with more tremors expected in the coming weeks, experts warn. It follows fears raised...

    Baked clay tablets from ancient Assyria, dating back as much as 4,000 years, could reveal the locations of 11 'lost cities' in modern-day Turkey. Harvard researchers analysed tablets found in the ancient city of Kanesh, the 12,000 cuneiform trade records include business transactions, accounts, seals and contracts. The researchers used mathematical models based on the price of goods and how frequently goods travelled between trade hubs to track down the locations of the ancient cities. Researchers reconstructed an economic network of trade goods such as wool, wine and precious metals across the Anatolian plateau in the 19th Century BC. The...

    Sometimes legends are true. Sunken cities are typically the stuff of legend, but now archaeologists have found the real thing hiding deep within Lake Van in Turkey. After a decade of searching the Middle East's second largest lake, the home of a lost kingdom has been found hundreds of metres beneath the surface. Archaeologists from the Van Yüzüncü Yıl University announced the incredible discovery - a vast 3,000-year-old castle preserved deep within the lake in amazing condition. The researchers worked closely with an independent team of divers to find their prize. Lost underwater cities and castles are a popular motif...

    Upsurge in big earthquakes predicted for 2018 as Earth rotation slows Scientists say number of severe quakes is likely to rise strongly next year because of a periodic slowing of the Earths rotation Scientists have warned there could be a big increase in numbers of devastating earthquakes around the world next year. They believe variations in the speed of Earths rotation could trigger intense seismic activity, particularly in heavily populated tropical regions. Although such fluctuations in rotation are small changing the length of the day by a millisecond they could still be implicated in the release of vast...

    We've got some big questions about Mars, but one of its most compelling mysteries just got a lot more intense. "Recurring slope lineae" (RSL) are dark streaks, first discovered in 2011, that appear seasonally on parts of the Mars landscape. In 2015, researchers took RSL as evidence of active salt water flows on the red planet. In 2017, new findings suggest RSL may actually be from shifting sand and dust. NASA titled its 2015 release "NASA Confirms Evidence That Liquid Water Flows on Today's Mars." Monday's release is called "Recurring Martian Streaks: Flowing Sand, Not Water?" It shows how new...
  • Weird Dark Streaks on Mars May Not Be Flowing Water After All

    Space.com ^ | | November 20, 2017 05:24pm | Calla Cofield,
    In 2015, observations by NASA's Mars Reconnaissance Orbiter revealed trace amounts of water(mixed with heavy doses of salts) on the Red Planet's surface. These "hydrated salts" corresponded with dark streaks on Martian hillsides called recurring slope lineae (RSL), which researchers had already identified as possible sites of liquid water rising to the surface. Studies of RSL, and in particular the findings by the MRO, introduced the tantalizing possibility that there could be enough liquid water on the surface of Mars today to support microbial life But the new study shows that those dark RSL could simply be flows of sand...

    The Voyager mission was only supposed to last four years. But four decades after the launch of Voyager 1 and 2, the spacecraft are still sending back messages from the farthest reaches of the final frontier When you think of legendary voyages of discovery you probably think of Columbus and Magellan, or Neil Armstrong walking on the moon. But what may be the greatest journey of exploration mankind has ever undertaken is happening right now. It began in 1977 when NASA launched two spacecraft named Voyager 1 & 2. The mission was only supposed to last four years, but now,...

    The plan for an artificial Martian magnetosphere may sound fanciful, but researchers say that emerging research is starting to show that a miniature magnetosphere can be used to protect humans and spacecraft.NASA Earth is most fortunate to have vast webs of magnetic fields surrounding it. Without them, much of our atmosphere would have been gradually torn away by powerful solar winds long ago, making it unlikely that anything like us would be here.Scientists know that Mars once supported prominent magnetic fields as well, most likely in the early period of its history when the planet was consequently warmer and...
  • Study reveals how a very low calorie diet can reverse type 2 diabetes

    11/19/2017 11:55:58 AM PST · by ConservativeMind · 50 replies
    In a new study, a Yale-led research team uncovers how a very low calorie diet can rapidly reverse type 2 diabetes in animal models. The research team investigated the effects of a very low calorie diet (VLCD), consisting of one-quarter the normal intake, on a rodent model of type 2 diabetes. Using this approach the researchers pinpointed three major mechanisms responsible for the VLCD's dramatic effect of rapidly lowering blood glucose concentrations in the diabetic animals. In the liver, the VLCD lowers glucose production by: 1) decreasing the conversion of lactate and amino acids into glucose; 2) decreasing the rate...

    The only place you’d expect to encounter the “unmistakable smell of rotting flesh” these days would be at a slaughterhouse. In Victorian London, you’d find it in an operating room. A “surgeon, wearing a blood-encrusted apron, rarely washed his hands or his instruments and carried with him … the unmistakable smell of rotting flesh . . . cheerfully referred to as ‘good old hospital stink,’ ” writes Lindsey Fitzharris, author of “The Butchering Art: Joseph Lister’s Quest to Transform the Grisly World of Victorian Medicine,” out now. At the time, the medical community was unaware of the existence of germs and didn’t know...

    Farting, breaking wind, cutting the cheese, or gas. The English language has numerous words for flatulence and this is even before we devolve into the subcategories that make up the genre. Whatever you call it, farting is a taboo act, but it is also a source of fascination. Its not for nothing that there is a popular childrens book series called Fart Squad or that the preview of the most recent installment of the Alvin and the Chipmunks dynasty led with the punchline, Sorry, pizza toots. Today farting is something for which we perfunctorily ask forgiveness, but in the past...

    The Assocation of Mature American Citizens ^ | November 16, 2017 | John Grimaldi
    WASHINGTON, DC Is old age a disease? Dan Weber, president of the Association of Mature American Citizens [AMAC], says a significant amount of scientific research indicates that aging is, indeed, a disease. More important there are many who believe it is a disease with a cure. Weber cites the work of Dr. Aubrey de Grey, a well-known biomedical gerontologist. His focus is on extending life spans by intervening at the cellular level, repairing damaged cells and in turn extending life. Some call de Grey a mad scientist but there is lots of independent study being conducted by those in...
  • Earthbound Antimatter Mystery Deepens After Scientists Rule Out Pulsar Source

    The recent finding, detailed in the journal Science today(Nov. 17), concerns positrons, the antimatter complements of electrons. High-energy particles, usually protons, traveling across the galaxy can create pairs of positrons and electrons when they interact with dust and gas in space, study co-author Hao Zhou, at Los Alamos National Lab, told Space.com. In 2008, the space-based PAMELAdetector measured unexpectedly high numbers of earthbound positrons. This was about 10 times what they were expecting to see, according to Zhou. ... Zhou's team made detailed measurements of the gamma-rays coming from the direction of two nearby pulsars Geminga and its companion...

    Hrvard Business Review ^ | October 25, 2017 | by Alessandro Di Fiore
    For the last decade, the 3D printing sector has been dominated by closed systems, in which 3D printers could only be used with the manufacturers resin and software. The trouble with closed systems is that they limit innovation. One printer manufacturer alone cannot offer the variety of materials needed for the thousands of potential 3D printing applications. As a result, the development of new end-user applications and materials has stalled, and growth in 3D printing has plateaued. To break out, the industry must reinvent itself and become open. There has been progress in that direction. Players from adjacent industries have...

    About 11 light-years away, Ross 128 b is closer to the solar system than any known exoplanet save Proxima b. First there was Proxima b, the Earth-sized planet orbiting the closest star to us, Proxima Centauri. Then came the seven Earth-sized worlds orbiting TRAPPIST-1, a star 39 light-years away, three of which are in the habitable zone. Now we welcome a new tantalizing exoplanet to the group, the second closest we know of, also Earth-sized and temperate, orbiting a calm red dwarf star: Ross 128 b. Ross 128 is an old, inactive red dwarf star that sits 11 light-years away....

    Solid-state batteries represent the holy grail for automakers as they promise a driving range for electric cars comparable to internal combustion models, along with charging that could end up quicker than the time it takes to fill a gas tank. Revived electric car company Fisker has now revealed that its filed patents for solid-state battery technology that could enable a range of 500 miles and a charging time of just one minute. The key are three-dimensional electrodes that have 25 times more surface area than flat thin-film solid-state electrodes, along with high electronic and ionic conductivities. According to Green Car...

    A memory prosthesis brain implant has enhanced human memory for the first time. The device is comprised of electrodes implanted in the brain, and is designed to mimic the way we naturally process memories, and can boost performance on memory tests by up to 30 per cent. A similar approach may work for enhancing other brain skills, such as vision or movement, says the team behind the work. We are writing the neural code to enhance memory function, says Dong Song of the University of Southern California, who presented the findings at the Society for Neuroscience meeting in Washington DC...
