  • Hidden hazards that could trigger huge quakes and tsunamis off Californian coast (trunc)

    Dailymail.com ^ | 29 May 2015 | Ellie Zolfagharifard For
    Researchers say that several long faults could cause magnitude 8.0 quakes and tsunamis within 90 miles (145km) of the coast. 'We're dealing with continental collision,' said geologist Mark Legg of Legg Geophysical in Huntington Beach, California, regarding the cause of the offshore danger. 'That's fundamental. That's why we have this mess of a complicated logjam.' The logjam Legg referred to is composed of blocks of the Earth's crust caught in the ongoing tectonic battle between the North American tectonic plate and the Pacific plate. The blocks are wedged together all the way from the San Andreas Fault on the east,...

    On Friday, the second day of its annual developer conference, Google I/O, one of the search giant’s semi-secretive research divisions announced a project that aims to make conductive fabrics that can be weaved into everyday clothes. The effort, called Project Jacquard, is named for the French inventor of the Jacquard Loom, which revolutionized textile manufacturing and helped pave the way for modern computing. Much like the screens on mobile phones, these fabrics could register the user’s touch and transmit information elsewhere, like to a smartphone or tablet computer. They are made from conductive yarns that come in a rainbow of...

    Archaeology in Bulgaria ^ | May 26, 2015 | Ivan Dikov
    The Byzantine vessel has been found at a depth of 82 meters, and is up to 120-125 meters long... The divers have found hundreds of amphorae which were allegedly transported on the sunken vessel, and probably contained oils or wine... there are over 100 amphorae, most of which are intact and sealed with wax, and that the shipwreck must be at least 1,000 years old. The average size of the amphorae is about 75 cm (appr. 2.5 feet) in height, and 50 cm (app. 1.7 feet) in length... The Russian underwater archaeologists and divers are not even sure whether the...

    NASA ^ | May 30, 2015 | (see photo credit)
    Explanation: Many bright nebulae and star clusters in planet Earth's sky are associated with the name of astronomer Charles Messier, from his famous 18th century catalog. His name is also given to these two large and remarkable craters on the Moon. Standouts in the dark, smooth lunar Sea of Fertility or Mare Fecunditatis, Messier (left) and Messier A have dimensions of 15 by 8 and 16 by 11 kilometers respectively. Their elongated shapes are explained by an extremely shallow-angle trajectory followed by the impactor, moving left to right, that gouged out the craters. The shallow impact also resulted in two...

    NASA ^ | May 29, 2015 | (see photo credit)
    Explanation: Telescopic observers on Earth have been treated to spectacular views of Saturn lately as the ringed planet reached its 2015 opposition on May 23 at 0200 UT. Of course opposition means opposite the Sun in Earth's sky. So near opposition Saturn is up all night, at its closest and brightest for the year. These sharp images taken within hours of the Sun-Earth-Saturn alignment also show the strong brightening of Saturn's rings known as the opposition surge or the Seeliger Effect. Directly illuminated, the ring's icy particles cast no shadows and strongly backscatter sunlight toward planet Earth, creating the dramatic...

    Los Angeles Times ^ | May 29, 2015 | T.L. Stanley
    No need to head to the multiplex for big action, special effects and hair-raising thrills, says bestselling author James Patterson, when the CBS adaptation of his novel, "Zoo," promises all that — and rampaging wildlife, to boot. "It should give the summer movies a run for their money," said Patterson, a populist literary star perhaps best known for his Alex Cross franchise, less so for being understated. "There's horror, sci-fi, suspense. It's kind of James Patterson meets Stephen King meets Michael Crichton. It's a scary fable."

    The Washington Post ^ | May 28, 2015 | Todd C. Frankel
    The Salton Sea is the largest lake in California, 360 square miles of unlikely liquid pooled in the middle of the Sonoran Desert. Now the sea is slipping away. The Salton Sea needs more water — but so does just about every other place in California. And what is happening here perfectly illustrates the fight over water in the West, where epic drought has revived decades-old battles and the simple solutions have all been tried. Allowing the Salton Sea to shrink unabated would be catastrophic, experts say. Dried lake bed, called playa, is lighter and flies farther than ordinary soil....

    Hindustan Times ^ | May 29 2015 | unknown
    In an emotional get-together, a woman has met for the first time a man who received her late brother's face in a groundbreaking transplant. Rebekah Aversano visited Richard Norris at his Virginia home and stroked his face — which once belonged to her 21-year-old brother Josh. "Do you mind if I touch it?" Aversano asked during the emotional meeting filmed by "60 Minutes Australia'. The family of Aversano had donated the face of Josh to Richard Norris, who had suffered severe facial disfigurement after accidentally shooting himself in 1997 when he was 22. Norris, now 39, had undergone dozens of...

    SmarterEveryDay | April 24, 2015 | Destin Sandlin
    Many people believe you never forget how to ride a bike, but Destin Sandlin of the YouTube series Smarter Every Day might have just proved that theory wrong. When a fellow engineer presents him with a bicycle built so that the wheel turns the opposite direction of the handlebars, Destin realizes that this seemingly simple challenge is almost impossible. As Destin and behavioral scientists explain, this happens because our brains are so preconditioned to certain movements and muscle memory that going against these natural instincts is incredibly difficult. In fact, it is much easier for a child than an adult...

    Geek.com ^ | 5/23/15 | Ryan Whitwam
    In the center of most galaxies (ours included) there is a supermassive black hole that holds everything together. However, one galaxy 10.5 billion light years away looks like it might have two black holes, and just like in Highlander, there can be only one. Scientists believe the pair are going to crash into each other in just 21 years. This could provide an unprecedented opportunity to observe the mind-boggling physics of such an event. The galaxy in question doesn’t have a snazzy name — it’s known only as PSO J334.2028+01.4075. It’s what is known as a quasar, or an “active...
  • Experiment confirms quantum theory weirdness

    PhysOrg ^ | 5/27/15
    The bizarre nature of reality as laid out by quantum theory has survived another test, with scientists performing a famous experiment and proving that reality does not exist until it is measured. Physicists at The Australian National University (ANU) have conducted John Wheeler's delayed-choice thought experiment, which involves a moving object that is given the choice to act like a particle or a wave. Wheeler's experiment then asks - at which point does the object decide? Common sense says the object is either wave-like or particle-like, independent of how we measure it. But quantum physics predicts that whether you observe...
  • What is Lunar Regolith?

    05/28/2015 4:02:36 PM PDT · by BenLurkin · 19 replies
    The surface of the Moon is covered with a fine powdery material that scientists refer to it as “lunar regolith”. Nearly the entire lunar surface is covered with regolith, and bedrock is only visible on the walls of very steep craters. The Moon regolith was formed over billions of years by constant meteorite impacts on the surface of the Moon. Scientists estimate that the lunar regolith extends down 4-5 meters in some places, and even as deep as 15 meters in the older highland areas. ... However, landings performed by robotic Surveyor spacecraft showed that the lunar soil was firm...

    Eureka! After about a century of research, Swiss scientists have finally cracked the mystery of the holes in Swiss cheese. Despite what you may have been told as a child, they are not caused by mice nibbling away inside cheese wheels. Experts from Agroscope, a state centre for agricultural research, said the phenomenon—which marks famous Swiss cheeses such as Emmental and Appenzell—was caused by tiny bits of hay present in the milk and not bacteria as previously thought. They found that the mystery holes in such cheeses became smaller or disappeared when milk used for cheese-making was extracted using modern...

    The 24-minute-long earthquake prophecy video, which has now been watched by over half-a-million people, predicts a massive 9.8 earthquake will hit California at 4pm local time on 28 May. The clip published by Frank Hoogerbeets, the founder and president of Ditrianum Media, claims he was able to assess the 'horrific' event using a computer program called Solar System Scope. The Huffington Post UK citing Hoogerbeets noted that his theory was based on the calculation that the 9.8 quake will strike when "no less than five planetary alignments will converge with the Earth." He claims that even Nostradamus, the famous French...

    Explanation: Large spiral galaxy NGC 4945 is seen edge-on near the center of this cosmic galaxy portrait. In fact, NGC 4945 is almost the size of our own Milky Way Galaxy. Its own dusty disk, young blue star clusters, and pink star forming regions standout in the sharp, colorful telescopic image. About 13 million light-years distant toward the expansive southern constellation Centaurus, NGC 4945 is only about six times farther away than Andromeda, the nearest large spiral galaxy to the Milky Way. Though the galaxy's central region is largely hidden from view for optical telescopes, X-ray and infrared observations indicate...

    Geneticists from the University of Leicester have discovered that most European men descend from just a handful of Bronze Age forefathers, due to a 'population explosion' several thousand years ago. The project, which was funded by the Wellcome Trust, was led by Professor Mark Jobling from the University of Leicester's Department of Genetics and the study is published in the journal Nature Communications. The research team determined the DNA sequences of a large part of the Y chromosome, passed exclusively from fathers to sons, in 334 men from 17 European and Middle Eastern populations. This research used new methods for...

    Explanation: What could cause the center of M94 to be so bright? Spiral galaxy M94 has a ring of newly formed stars surrounding its nucleus, giving it not only an unusual appearance but also a strong interior glow. A leading progenitor hypothesis holds that an elongated knot of stars known as a bar rotates in M94 and has generated a burst of star formation in the inner ring. Recent observations have revealed the outer, fainter ring is not closed and relatively complex. M94, pictured here spans about 30,000 light years, lies about 15 million light years away, and can be...

The photographer stayed up until 2 am, waiting until the Milky Way Galaxy rose above the level of a majestic looking oak. From this carefully chosen perspective, dust lanes in the galaxy appear to be natural continuations to branches of the tree. Last came the light. A flashlight was used on the far side of the tree to project a silhouette. By coincidence, other trees also appeared as similar silhouettes across...

Sometimes, if you looked out the window of an airplane at just the right place and time, you could have seen something very unusual -- a space shuttle launching to orbit. Images of the rising shuttle and its plume became widely circulated over the web shortly after Endeavour's final launch in 2011 May. The above image was taken from a shuttle training aircraft by NASA and is not copyrighted. Taken well above the clouds, the image can be matched with similar images of the same shuttle plume taken below the...

    Explanation: Hot, young stars and cosmic pillars of gas and dust seem to crowd into NGC 7822. At the edge of a giant molecular cloud toward the northern constellation Cepheus, the glowing star forming region lies about 3,000 light-years away. Within the nebula, bright edges and dark shapes are highlighted in this colorful skyscape. The image includes data from narrowband filters, mapping emission from atomic oxygen, hydrogen, and sulfur into blue, green, and red hues. The atomic emission is powered by energetic radiation from the hot stars, whose powerful winds and radiation also sculpt and erode the denser pillar shapes....

    The teeming plant world could become a virtual mystery in the coming decades as college students increasingly shy away from studying botany and universities across the U.S. shutter their long-standing herbaria. Since 1988, the number of research universities offering botany degrees has dropped by half, according to National Science Foundation research funding statistics. And the National Center for Education Statistics reports that fewer than 400 undergraduate, graduate and doctoral botany degrees were awarded in 2012. Educators say that’s because students are being pushed into more modern, technology-related majors. Current botanists fear that will lead to a dearth of people able...

Although having a large bust and never-ending pins are deemed by western culture as the epitome of femininity, when choosing a mother for their children, men look for brains first, Professor David Bainbridge, of the University of Cambridge said that intelligence is by far the most attractive quality for men looking for a long term partner because it demonstrates that his chosen partner is likely to be a responsible parent.

    An investigative author from New Mexico with a history of scientifically debunking the chupacabra myth says he can explain sightings of the mythical creature. "When you do DNA testing on these alleged chupacabras, they're known animals," Benjamin Radford, who authored the 2011 book "Tracking the Chupacabra," told New Mexico television station KOB. "They are coyotes or dogs. In some cases, they're raccoons. The hairlessness can be explained by a disease called sarcoptic mange, which is caused by skin mites." Animals with advanced mange often die when exposed to cold, but because of warmer temperatures brought on by climate change, those...

    Roses aren't red and violets aren't blue. At least that's the premise of a new book, 'Outside Color', which puts forward the debate that colour is, in fact, an illusion. Author Dr Mazviita Chirimuuta uses the book to explore the historical debates that suggest colour doesn't exist - at least not in the literal sense. Light, however, does exist, and it's the mind that transforms that light into colour. 'Of all the properties that objects appear to have,'writes the University of Pittsburgh professor, 'colour hovers uneasily between the subjective world of sensation and the objective world of fact.' Optical illusions,...

"Our new findings mean that the research community now needs to reconsider the assumption that our ancestors moved to Europe and succeeded where Neanderthals failed because of cultural and technological innovations brought from Africa or west Asia." By re-examining the evidence, the researchers showed that the comparable stone weapons appeared...

    Sometime about 220 million years ago, a meandering stream flowed here and plants grew along its banks. Something, as yet unknown, caused sediment to flood the area rapidly, which helped preserve the plants. Gulbranson splits open a grey slab of siltstone in the quarry to reveal amazingly well-preserved Triassic plant fossils, as if the leaves and stems had been freshly pressed into the rock only yesterday. "It's a mixture of plants that don't exist anymore," he says, "but we have some plants in these fossil ecosystems that we might know today, like ginkgo." On the one end are fossils from...

But let’s say that one of these situations actually occurs, and humans are annihilated with the exception of one male and one female. Could humanity survive? The answer is a resounding...maybe, with the only certainty being that the surviving couple is going to be very, very busy. Variations on this scenario occur now and again in nature. They’re called bottlenecks, and they include any event that causes a drastic reduction in a population--think overhunting and natural disasters. Certain species, like dandelions, are great...

    The ancestors of modern wolves and dogs split into different evolutionary lineages 27,000 to 40,000 years ago, much earlier than some other research has suggested, scientists reported Thursday. The new finding is based on a bone fragment found on the Taimyr Peninsula in Siberia several years ago. When scientists studied the bone and reconstructed its genome — the first time that had been done for an ancient wolf, or any kind of ancient carnivore — they found it was a new species that lived 35,000 years ago. Based on the differences between the genome of the new species, called the...

    Scientists Map 5,000 New Ocean Viruses In the few decades since viruses were first found in the oceans, scientists have only been able to identify a handful of species. A new survey has uncovered nearly all the rest. Photographs by Jennifer Brum, Tucson Marine Phage LabA few of the more than 5,000 viruses discovered during the Tara Oceans Expedition. By: Carl ZimmerMay 21, 2015 In March 2011, the Tara, a 36-meter schooner, sailed from Chile to Easter Island — a three-week leg of a five-year global scientific expedition. All but one of the seven scientists aboard the ship spent much...

    On Wednesday night, two opposing beams of protons were steered into each other at the four collision points spaced around the LHC's tunnel. The energy of the collisions was 13 trillion electronvolts - dwarfing the eight trillion reached during the LHC's first run, which ended in early 2013. ... Prof David Newbold, from the University of Bristol, works on the CMS experiment. He said the new energies present new technical challenges. "When you accelerate the beams they actually get quite a lot smaller - so the act of actually getting them to collide inside the detectors is really quite an...

    Explanation: NGC 6240 offers a rare, nearby glimpse of a cosmic catastrophe in its final throes. The titanic galaxy-galaxy collision takes place a mere 400 million light-years away in the constellation Ophiuchus. The merging galaxies spew distorted tidal tails of stars, gas, and dust and undergo fast and furious bursts of star formation. The two supermassive black holes in the original galactic cores will also coalesce into a single, even more massive black hole and soon, only one large galaxy will remain. This dramatic image of the scene is a composite of narrowband and near-infrared to visible broadband data from...

    Physicists find ways to increase antihydrogen production 18 hours ago by Lisa Zyga feature Antihydrogen consists of an antiproton and a positron. Credit: public domain (Phys.org)—There are many experiments that physicists would like to perform on antimatter, from studying its properties with spectroscopic measurements to testing how it interacts with gravity. But in order to perform these experiments, scientists first need some antimatter. Of course, they won't be finding any in nature (due to antimatter's tendency to annihilate in a burst of energy when it comes in contact with ordinary matter), and creating it in the lab has proven to...

    The New Mexico Law Review is devoting its entire spring issue to eight contemporary legal issues – as seen through the entertaining but nonetheless very serious lens of a “Breaking Bad” perspective. Eight articles and essays include analyses of criminal procedure, a hypothetical arrest of Walter White, attorney-client communications, police practices, the war on drugs, and morality and the law. The Law Review, edited by University of New Mexico School of Law students, is due out Friday. An electronic version already has been posted online at lawschool.unm.edu/nmlr/current-issue.php. The Law Review’s faculty adviser, Professor Dave Sidhu, described the issue as creative...

    A new class of magnets that expand their volume when placed in a magnetic field and generate negligible amounts of wasteful heat during energy harvesting, has been discovered by researchers at Temple University and the University of Maryland. The researchers, Harsh Deep Chopra, professor and chair of mechanical engineering at Temple, and Manfred Wuttig, professor of materials science and engineering at Maryland, published their findings, "Non-Joulian Magnetostriction," in the May 21st issue of the journal, Nature. This transformative breakthrough has the potential to not only displace existing technologies but create altogether new applications due to the unusual combination of magnetic...

    For example, at last month's Convergence: Digital Television and Internet conference in San Jose, Stephen Weiswasser, president and CEO of the Americast consortium, was decidedly bearish. "The number of people on-line and the growth rate of on-line is decreasing significantly," he was quoted as saying. "Right now, it appears that the average customer knows that the Web is not all it's cracked up to be." After a bit of analysis, I've determined that Weiswasser is right — and wrong at the same time. Without numbers to back up his claim that the on-line world is shrinking, I won't argue that...

    University of Montreal study finds video game players navigate the screen using a key area of the brain Millions of boys could be at increased risk of Alzheimer's disease and other mental illnesses in later life through playing action video games such as Call of Duty or Assassin's Creed, according to new research. Scientists say players navigate the screen using a key area of the brain called the caudate nucleus, which leads to loss of grey matter in the hippocampus. Previous studies have shown reduced volume in the hippocampus, which controls memory, learning and emotion, is associated with neurological and...

    Owen Maroney worries that physicists have spent the better part of a century engaging in fraud. Ever since they invented quantum theory in the early 1900s, explains Maroney, who is himself a physicist at the University of Oxford, UK, they have been talking about how strange it is — how it allows particles and atoms to move in many directions at once, for example, or to spin clockwise and anticlockwise simultaneously. But talk is not proof, says Maroney. “If we tell the public that quantum theory is weird, we better go out and test that's actually true,” he says. “Otherwise...

    Better hurry up and fetch your ice cubes! The Antarctic is claimed to be melting at an unprecedented rate. NASA wants you believe that “Massive Antarctic Ice Shelf Will Be Gone Within Years.” More specifically, a team led by Ala Khazendar of NASA’s Jet Propulsion Laboratory has found that the ice is melting so fast that the shelf will be gone before 2020. Presumably, that’s the good news. The bad news is that it’s all Hullabaloo. Neither the Arctic nor the Antarctic sea-ice is melting at any rate out of the norm. In fact, the opposite is true. As of...
