Alaska Gets 'Artificial Aurora' As HAARP Antenna Array Listens Again ( 17

Freshly Exhumed quotes Hackaday: The famous HAARP antenna array is to be brought back into service for experiments by the University of Alaska. Built in the 1990s for the US Air Force's High Frequency Active Auroral Research Program, the array is a 40-acre site containing a phased array of 180 high-frequency antennas and their associated high-power transmitters. Its purpose is to conduct research on charged particles in the upper atmosphere, but that hasn't stopped an array of bizarre conspiracy theories.
A university space physics researcher will actually create an artificial aurora starting Sunday (and continuing through Wednesday) to study how yjr atmosphere affects satellite-to-ground communications, and "observers throughout Alaska will have an opportunity to photograph the phenomenon," according to the University. "Under the right conditions, people can also listen to HAARP radio transmissions from virtually anywhere in the world using an inexpensive shortwave radio."

SpaceX's Next Launch Carries Colonies Of A Drug-Resistant Superbug ( 45

An anonymous reader quotes Business Insider: SpaceX is preparing to launch a lethal, antibiotic-resistant superbug into live its days in the microgravity environment of the International Space Station. The idea is not to weaponize space with MRSA -- a bacterium that kills more Americans every year than HIV/AIDS, Parkinson's disease, emphysema, and homicide combined -- but to send its mutation rates into hyperdrive, allowing scientists to see the pathogen's next moves well before they appear on Earth. The NASA-funded study will see SpaceX's Falcon 9 rocket launch colonies of MRSA into space, to be cultivated in the US National Laboratory on the International Space Station.

"We will leverage the microgravity environment on the ISS to accelerate the Precision Medicine revolution here on Earth," lead researcher Anita Goel, CEO of biotech company Nanobiosym, told Yahoo News... "Our ability to anticipate drug-resistant mutations with Gene-RADAR will lead to next generation antibiotics that are more precisely tailored to stop the spread of the world's most dangerous pathogens," says Goel.

That launch was scheduled for today, but postponed it to "take a closer look at positioning of the second stage engine nozzle." Two more externally-mounted payloads will conduct other experiments, with one monitoring lightning strikes on earth and the other measuring chemicals in the earth's atmosphere. In addition, there's also 21 science experiments that were submitted by high school students

Meanwhile, Slashdot reader tomhath brings news that researchers have discovered the red berries of a U.S. weed can help fight superbugs. The researchers found "extracts from the Brazilian peppertree, which traditional healers in the Amazon have used for hundreds of years to treat skin and soft-tissue infections, have the power to stop methicillin-resistant MRSA infections in mice." One of the researchers said the extract "weakens the bacteria so the mouse's own defenses work better."

Juno Jupiter Probe Won't Move Into Shorter Orbit After All ( 51

NASA announced today that their Juno spacecraft will not move into a closer orbit around Jupiter as originally planned. "Juno slipped into a highly elliptical, 53-Earth-day-long orbit around Jupiter when it arrived at the giant planet on July 4, 2016," reports From their report: The probe was supposed to perform an engine burn in October to reduce its orbital period to 14 days, but an issue with two helium valves postponed that maneuver. The engine burn has now been canceled, meaning Juno will stay where it is through the end of its mission. "During a thorough review, we looked at multiple scenarios that would place Juno in a shorter-period orbit, but there was concern that another main engine burn could result in a less-than-desirable orbit," Rick Nybakken, Juno project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, said in a statement. "The bottom line is, a burn represented a risk to completion of Juno's science objectives." But Juno should still be able to accomplish its mission goals in the longer orbit, NASA officials said. In fact, the 53-day path will allow the probe to perform some "bonus science" in the outer regions of Jupiter's magnetosphere, they added.

Astronomers Discover 60 New Planets Including 'Super Earth' ( 38

schwit1 quotes a report from New York Post: An international team of astronomers has found 60 new planets orbiting stars close to Earth's solar system, including a rocky "super Earth." The experts also found evidence of an additional 54 planets, bringing the potential discovery of new worlds to 114. One planet in particular, Gliese 411b, has been generating plenty of attention. Described as a "hot super Earth with a rocky surface," Gliese 411b is located in the fourth-nearest star system to the Sun, making it the third-nearest planetary system to the Sun, according to the U.K.'s University of Hertfordshire, which participated in the research. Gliese 411b (also known as GJ 411b or Lalande 21185) orbits the star Gliese 411 (or GJ 411). Despite the "super Earth" label, Dr. Mikko Tuomi from University of Hertfordshire's Centre for Astrophysics told Fox News that Gliese 411b is too hot for life to exist on its surface. The 60 new planets are found orbiting stars that are mostly some 20 to 300 light years away, according to Tuomi. The discoveries are based on observations taken over 20 years by U.S. astronomers using the Keck-I telescope in Hawaii as part of the Lick-Carnegie Exoplanet Survey. During the course of the research, scientists obtained almost 61,000 observations of 1,600 stars, which are now available to the public.

Lost Winston Churchill Essay Reveals His Thoughts On Alien Life ( 183

"A newly discovered essay by Winston Churchill shows that the British statesman gave a lot of thought to the existential question that has inspired years of scientific research and blockbuster movies: are we alone in the University?" reports The Verge. "The essay was drafted in the 1930s, but unearthed in a museum in Missouri last year." Astrophysicist Mario Livio was the first scientist to analyze the article and has published his comments in the journal Nature. The Verge reports: Livio was "stunned" when he first saw the unpublished, 11-page essay on the existence of alien life, he tells The Verge. The astrophysicist was visiting Westminster College in Fulton, Missouri, for a talk last year, when he was approached by Timothy Riley, the director of Fulton's US National Churchill Museum. Riley showed him the essay, titled "Are We Alone in the Universe?" In the essay, Churchill reasons that we can't possibly be alone in the Universe -- and that many other Suns will likely have many other planets that could harbor life. Because of how enormously distant these extrasolar planets are, we may never know if they "house living creatures, or even plants," Churchill concludes. He wrote this decades before exoplanets were discovered in the 1990s; hundreds have since been detected. What's impressive about the essay is the way Churchill approaches the existential and scientific question of whether life exists on other planets, Livio says. Churchill's reasoning mirrors extremely well the way scientists think about this problem today. The British leader also talks about several theories that still guide the search for alien life, Livio says. For example, he notes that water is the key ingredient for life on Earth, and so finding water on other planets could mean finding life there. Churchill also notes that life can only survive in regions "between a few degrees of frost and the boiling point of water" -- what today we call the habitable zone, the region around a star that is neither too hot or too cold, so that liquid water may exist on the planet's surface.

JavaScript Attack Breaks ASLR On 22 CPU Architectures ( 152

An anonymous reader quotes a report from BleepingComputer: Five researchers from the Vrije University in the Netherlands have put together an attack that can be carried out via JavaScript code and break ASLR protection on at least 22 microprocessor architectures from vendors such as Intel, AMD, ARM, Allwinner, Nvidia, and others. The attack, christened ASLRCache, or AnC, focuses on the memory management unit (MMU), a lesser known component of many CPU architectures, which is tasked with improving performance for cache management operations. What researchers discovered was that this component shares some of its cache with untrusted applications, including browsers. This meant that researchers could send malicious JavaScript that specifically targeted this shared memory space and attempted to read its content. In layman's terms, this means an AnC attack can break ASLR and allow the attacker to read portions of the computer's memory, which he could then use to launch more complex exploits and escalate access to the entire OS. Researchers have published two papers [1, 2] detailing the AnC attack, along with two videos[1, 2] showing the attack in action.

ISRO Makes History, Launches 104 Satellites With Single Rocket ( 157

neo12 writes: Indian Space Research Organization (ISRO) made history by launching 104 satellites in a single launch. The lift-off of PSLVC 37 at 9.28 am from Sriharikota was a perfect one. In 28 minutes, all 104 satellites were successfully placed into the Earth's orbit. 101 of the 104 satellites belong to six foreign countries, including 96 from the U.S. and one each from Israel, the UAE, the Netherlands, Switzerland and Kazakhstan. According to Times of India, "Russian Space Agency held a record of launching 37 satellites in one go during its mission in June 2014. India previously launched 23 satellites in a single mission in June 2015."

New Office Sensors Know When You Leave Your Desk ( 158

An anonymous reader quotes a report from Bloomberg: About a year ago, in a widely reported story, journalists at British newspaper the Telegraph found little black boxes installed under their desks. The devices, which had "OccupEye" emblazoned on them, detected if employees were at their workstations. Not shockingly, writers and editors were suspicious, worried that bosses were monitoring their moves, even their bathroom breaks. The National Union of Journalists complained to management about Big Brother-style surveillance. The company insisted the boxes were intended to reduce energy costs, ensuring that empty cubicles weren't overheated or over-air-conditioned, but the damage was done, and the devices were removed. Sensors that keep tabs on more than temperature are already all over offices -- they're just less conspicuous and don't have names that suggest Bond villains. "Most people, when they walk into buildings, don't even notice them," says Joe Costello, chief executive officer of Enlighted, whose sensors, he says, are collecting data at more than 350 companies, including 15 percent of the Fortune 500. They're hidden in lights, ID badges, and elsewhere, tracking things such as conference room usage, employee whereabouts, and "latency" -- how long someone goes without speaking to another co-worker. Proponents claim the goal is efficiency: Some sensors generate heat maps that show how people move through an office, to help maximize space; others, such as OccupEye, tap into HVAC systems.

Gravity-Detecting LIGO Also Found To Be Creating Gravity Waves ( 82

LIGO is a large-scale physics experiment to detect "ripples in spacetime," as well as gravity waves from outer space. But it turns out that it's also creating gravity waves, according to a team of physicists led by Belinda Pang, a physicist at the California Institute of Technology. sciencehabit quotes Science magazine: Although these waves are far too feeble to detect directly, the researchers say, the radiation in principle could be used to try to detect weird quantum mechanical effects among large objects... Of course, LIGO doesn't generate large gravitational waves -- you could probably make bigger ones yourself by whirling bowling balls around -- but it does so with optimal efficiency [and] the waves could still be used to probe quantum effects among macroscopic objects, Pang says.

Quantum mechanics says that a vanishingly small object such as an electron can literally be in two places in once. Many physicists suspect that it might just be possible to coax a macroscopic object, such as one of LIGO's mirrors, into a similar state of quantum motion. That delicate state wouldn't last long, as interactions with the outside world would make it "decohere" and put it in one place or another. However, one could imagine measuring the rate at which such a state decoheres to see whether it matches the rate expected from the radiation of gravitational waves, Pang says.

"It's unbelievably difficult," Pang says. "But if you want to do it, what we're saying is that LIGO is the best place to do it."

Space Junk-Fighting Cable Fails To Deploy ( 55

New Scientist reports: It's a rubbish start for the world's first space clean-up experiment. A cable designed to drag space junk out of orbit has failed to deploy from a Japanese spacecraft... A 700-metre-long metal cable was fitted to an unmanned spacecraft called Kounotori 6, which was on its way back to Earth after delivering supplies to the International Space Station. The cable was meant to unfurl from the spacecraft, at which point an electric current would pass along its length. The idea was that the current would interact with the Earth's magnetic field, creating a drag that pulled the spacecraft out of orbit. The spacecraft would then tumble into our atmosphere and become incinerated... However, Kounotori 6 was unable to release the cable to test its junk-removing potential, and JAXA could not fix the glitch before the spacecraft returned to Earth's atmosphere this morning... "Releasing a cable may seem simple, but nothing in space is simple," says Sean Tuttle at the University of New South Wales in Australia... The test's failure should be seen as a setback rather than a nail in the coffin for junk-removing cables, Tuttle says.
rickyslashdot writes: Because of the simplicity of this system, it is bound to be tested again -- hopefully sooner than later... This process is inherently safer than using rocket engines (to be attached to the junk), and is much less of a 'mass-to-orbit' cost, since it only requires a grappling system, and a spool of wire/cable. Hopefully, there will be a follow-up / re-try in the near future for this orbital debris clean-up process.

Magic Leap CEO Defends His AR Company After Leaked Photo ( 62

Saturday Business Insider claimed that augmented reality company Magic Leap was "scrambling to finish a working prototype before an important board meeting next week," publishing a photo described by their source as an early January prototype. An anonymous reader quotes Mashable: The image depicts a man with a kit on his back that looks as if it's in the early stages of development, but [CEO Rony] Abovitz's tweet suggested it was not intended as consumer technology. "The photo you are all excited about is NOT what you think it is," he wrote. "The photo shows an @magicleap R&D test rig where we collect room/space data for our machine vision/machine learning work. We do this in order to understand lighting, texture, various surfaces." As Mashable noted earlier, the leaked photo has done little to assuage fears the company's technology has been overhyped... A December report in The Information raised questions about whether Magic Leap was ready for primetime amid concerns that much of its work could not be commercialised or miniaturised. Two former employees also reportedly told the outlet a promotional video showing the technology in action was in fact created by the special effects company, Weta Workshop.
Magic Leap raised $1.39 billion from investors (including Google), and Abovitz's last tweet Saturday reassured fans that "We will not let you down." Mashable even suggested that "this might just be a bit of clever marketing spin by Magic Leap to greatly lower expectations before unveiling a polished product in the coming months... The worst case scenario is that this does represent the latest version of the company's prototype meant for consumers, in which case there's very little chance we will see a Magic Leap device available to consumers any time in 2017."

A Guide To Friday's Comet-Eclipse-Full-Moon Triple Feature ( 28

SonicSpike quotes a report from CNET: Even if you aren't a space nerd whose idea of a good time is craning your neck to stare into the vast nothingness of space on a frigid evening, this Friday the heavens will put on a show worth heading outdoors for. A penumbral lunar eclipse, a full "snow moon" and a comet will be spicing up the night sky February 10 in a rare convergence of such celestial happenings. We'll start with our nearest neighbor. February brings the full moon known as the "snow moon" because this month in North America tends to see a lot of the white fluffy stuff. This snow moon will be special though because, well... we'll all get in its way in a sense when the penumbral lunar eclipse takes place Friday. The eclipse will be at least partly visible from most but not all places on Earth (sorry Australia and Japan). The moment of greatest eclipse is at 4:43 p.m. PT and the eclipse will then dissipate until it completes a little over two hours later, according to the U.S. Naval Observatory. Next up, Comet 45P/Honda-Mrkos-Pajdusakova has actually been visible with binoculars and telescopes for several weeks already, but it will be at its closest approach to Earth on the morning of February 11 as it passes by at a distance of 7.4 million miles (11.9 million kilometers) or 30 times further away than the moon.

Jeff Bezos Talks About Music Streaming, and His Political Ambitions ( 69

In a wide-ranging interview with Billboard, Jeff Bezos, founder and CEO of Amazon, Blue Origin, and owner of The Washington Post, talked about music streaming business. He also talked about whether he desires to become the president of the United States. Excerpts from the interview: On music streaming business, being one of the late ones to join the party:Well, here's what I would say: We've been in the music category since 1998. It was the second category we launched after books. Our customers listen to a lot of music and we have a couple of freight trains kind of pulling the business along. One is Prime, and the other is Echo and Alexa.

On the prospect of seeing President Bezos and other political interests: Oh, no. I don't think so. No. I love my life. I love being an inventor. I love Blue Origin, my space company. I love The Washington Post. They are very good, but the Internet transition was difficult for them -- so I've been able to help them on that. But basically... I have a very full life. And I really like it.


Glass From Nuclear Test Site Shows the Moon Was Born Dry ( 48

An anonymous reader quotes a report from New Scientist: We can't recreate the giant impact that led to the moon's formation in a lab, but humans have made some other big explosions. By examining residue from the first detonation of a nuclear weapon, researchers have cracked a window into the moon's past. On 16 July 1945, the U.S. army detonated a nuclear weapon for the first time in an operation codenamed Trinity (see photo, above). As the bomb exploded with an energy equivalent to 20 kilotons of TNT, the sand underneath it melted, producing a thin sheet of mostly green glass dubbed trinitite. The explosion brought the area around the bomb to temperatures over 8000 C and pressures nearing 80,000 atmospheres. These extreme conditions are similar to those created as the moon formed in a colossal collision between Earth and another rock, probably about the size of Mars. Fortunately for planetary science, scientists meticulously measured and recorded the details of the Trinity detonation, so there is plenty of information to work with. Day and his colleagues took advantage of that past precision to investigate why the moon has surprisingly little water and other volatiles with a relatively low boiling point -- much less than Earth. To do so, they studied the distribution of one volatile element, zinc, in trinitite collected at different distances out from the explosion's center. They found that the closer to the explosion the trinitite formed, the less zinc it had, especially when it came to zinc's lighter isotopes. That's because these evaporated in the intense heat of the explosion, while the heavier isotopes didn't and so remained in the trinitite. The ratios of different forms of zinc left behind in trinitite showed remarkable parallels to what was observed in the moon rocks retrieved in the Apollo missions. This means that zinc and other volatile elements, most notably water, probably evaporated off the moon while it was being formed in a violent collision or soon afterward, while its surface was still incredibly hot. The study has been published in Science Advances.

We Finally Have a Computer That Can Survive the Surface of Venus ( 156

Planet Venus is one of the most inhospitable places in the solar system. The surface temperature there is 470C (878F). This has been one of the key challenges that has prevented us from deeply exploring Venus. Normal chips can only function until around 250C, but it appears, we will soon have a computer that can withstand Venus' weather. From a report on ArsTechnica: Now, researchers out of NASA's Glenn Research Centre appear to have cracked the other big problem with high-temperature integrated circuits: they've crafted interconnects -- the tiny wires that connect transistors and other integrated components together -- that can also survive the extreme conditions on Venus. The NASA Glenn researchers combined the new interconnects with some SiC transistors to create a ceramic-packaged chip. The chip was then placed into the GEER -- the Glenn Extreme Environments Rig, a machine that can maintain Venus-like temperature and pressure for hundreds of hours at a time. The chip, a simple 3-stage oscillator, kept functioning at a steady 1.26MHz for 521 hours (21.7) days before the GEER had to be shut down.

Apple Seeks To Position Metal as Part of New 3D Graphics Standard For Web ( 170

Mikey Campbell, writing for AppleInsider: Apple's WebKit team on Tuesday proposed a new Community Group at the World Wide Web Consortium (W3C) that will focus on developing a new standard API, perhaps based on Metal, for accelerating GPU-based 3D graphics and general computation for the web. Announced through Apple's WebKit blog, the new 'GPU for the Web' Community Group will discuss a potential next-generation web graphics API that can better leverage modern GPUs. Along with 3D content, Apple proposes GPU architecture might also be used to accelerate general web computations. As noted by Dean Jackson from the WebKit team, advancements in the GPU hardware space has led to identical enhancements in software APIs. He cites platform technologies like Apple's Metal, Microsoft's Direct3D 12 and the Khronos Group's Vulkan as offering lower overhead, and thus better performance, than the OpenGL standard. Unfortunately, the new graphics APIs contain nuanced architectural differences and are not available across all platforms, making them unsuitable for wide implementation on the web.

NYC Fines Airbnb Hosts For 'Illegal' Home Rentals ( 267

In October, New York Gov. Andrew Cuomo signed into law one of the nation's toughest restrictions on Airbnb, which includes hefty fines of up to $7,500 for people who rent out space in their apartments. Several month have passed and the New York Post has learned of "the first casualties of [the] newly enforceable law." The city has reportedly charged two hosts with a combined total of 17 violations, and since each violation comes with a $1,000 fine, it adds up to $17,000. From their report: Property owner Hank Freid -- who was once crowned one of NYC's "Worst Landlords" by a watchdog group in 2005 -- and real estate broker Tatiana Cames were slapped with 17 violations, at $1,000 apiece, for their allegedly illegal listings on Manhattan's Upper West Side and in Bedford-Stuyvesant, in Brooklyn, according to documents obtained by the Post. Freid, who manages the Marrakech Hotel, was hit with 12 violations for listing SROs in the building on several booking platforms, including, Expedia, Kayak, Hotwire, Travelocity, and Orbitz, the citations reveal. Meanwhile, Cames -- who was served with five violations -- allegedly posted five separate listings to Airbnb advertising 320 Macon St, which records show she purchased for $2.15M in 2015. The Macon St. property was discovered to have inadequate fire alarms, sprinklers, illegal subdivisions, and a confused bunch of French tourists in a rear unit, according the procured documents. Cames appears to be making money off the vacancies in the building as she attempts to fill the space, as the same units are advertised as "for rent" on her personal website. The listings also seem to suggest that drawing illegal Airbnb-ers into BedStuy will help "diversify" the locale. If Freid and Cames don't pull their listings, they could be hit with a second set of violations, at $5,000 a pop.

A Supermassive Black Hole Has Been Devouring a Star For a Decade ( 69

An anonymous reader quotes a report from USA Today: A massive black hole devoured a star over a 10 year period, setting a new record for the longest space meal ever observed, according to new research. Researchers spotted the ravenous black hole with NASA's Chandra X-ray Observatory and Swift satellite as well as ESA's XMM-Newton, according to a statement from NASA. When objects like stars get too close to black holes, the intense gravity of the black hole can rip the star apart in what's called a tidal disruption event (TDE), according to NASA. While some of the debris from the star is flung forward, parts of it are pulled back and ingested by the black hole, where it heats up and emits an X-ray flare, NASA said in a statement. The tidal disruption event spotted by the trio of X-ray telescopes, is unlike anything researchers have ever seen, lasting ten times longer than any observed incident of star's death caused by a black hole, according to research published in Nature Astronomy Feb. 6. The black hole, dubbed XJ1500+0154, is located in a galaxy 1.8 billion light-years from Earth. Researchers first spotted it in 2005 and it reached peak brightness in 2008, according to the statement. According to NASA, researchers believe that the black hole may have consumed the most massive star ever completely torn apart during a TDE.

Iris Scans and Fingerprints Could Be Your Ticket On British Rail ( 75

Mickeycaskill quotes a report from Rail passengers could use fingerprints or iris scans to pay for tickets and pass through gates, under plans announced by the UK rail industry. In its current form, the mobile technology is intended to allow passengers to travel without tickets, instead using Bluetooth and geolocation technology to track a passenger's movements and automatically charge their travel account at the end of the day for journeys taken. The Rail Delivery Group (RDG), which represents train operators and Network Rail, said further development could see passengers identified using biometric technology in a way similar to the facial-recognition schemes used at some UK airports to speed up border checks. The RDG said more than 200 research, design and technology projects have been identified to increase the railways' capacity and improve customer service. Other projects include new seat designs that could improve train capacity by up to 30 percent and folding seats that could boost space during peak times, including tables that could fold into seats.

SpaceX Plans to Start Launching Rockets Every Two To Three Weeks ( 104

Space Exploration Technologies, better known as SpaceX, plans to launch its Falcon 9 rockets every two to three weeks, its fastest rate since starting launches in 2010, once a new launch pad is put into service in Florida next week. From a report: The ambitious plan comes only five months after a SpaceX rocket burst into flames on the launch pad at the company's original launch site in Florida. SpaceX, controlled by billionaire Elon Musk, has only launched one rocket since then, in mid-January. "We should be launching every two to three weeks," SpaceX President Gwynne Shotwell said in an interview on Monday.
