SETI's 'Strong Signal' Came From Earth ( 89

Yesterday, it was reported that Russia has detected a strong signal around 11 GHz coming from HD164595, a star nearly identical in mass to the Sun and located about 95 light years away from Earth. Well, long story short the signal came Earth. Ars Technica reports: "First, astronomers with the search for extraterrestrial intelligence downplayed the possibility of an alien civilization. 'There are many other plausible explanations for this claimed transmission, including terrestrial interference,' Seth Shostak, a senior astronomer with SETI, wrote. Now the Special Astrophysical Observatory of the Russian Academy of Sciences has concurred, releasing a statement on the detection of a radio signal at the RATAN-600 radio astronomy observatory in southern Russia. 'Subsequent processing and analysis of the signal revealed its most probable terrestrial origin,' the Russian scientists said."

Hunt For Ninth Planet Reveals Distant Solar System Objects ( 151

schwit1 writes: Astronomers have discovered several new objects orbiting the Sun at extremely great distances beyond the orbit of Neptune. The most interesting new discovery is 2014 FE72: "2014 FE72 is the first distant Oort Cloud object found with an orbit entirely beyond Neptune," reports Carnegie Institution for Science. "It has an orbit that takes the object so far away from the Sun (some 3000 times farther than Earth) that it is likely being influenced by forces of gravity from beyond our Solar System such as other stars and the galactic tide. It is the first object observed at such a large distance." This research is being done as part of an effort to discover a very large planet, possibly as much as 15 times the mass of Earth, that the scientists have proposed that exists out there.

SETI Has Observed a 'Strong' Signal That May Originate From a Sun-like Star ( 279

An anonymous reader writes: The RATAN-600 radio telescope in Zelenchukskaya, Russia has detected a strong signal around 11 GHz (which is very unlikely to be naturally-caused) coming from HD164595, a star nearly identical in mass to the Sun and located about 95 light years from Earth. The system is known to have at least one planet. If the signal were isotropic, it would seem to indicate a Kardashev Type II civilization. While it is too early to draw any conclusions, the discovery will be discussed at an upcoming SETI committee meeting on September 27th. According to Paul Gilster, author of the Centauri Dreams website, "No one is claiming that this is the work of an extraterrestrial civilization, but it is certainly worth further study. Working out the strength of the signal, the researchers say that if it came from an isotropic beacon, it would be of a power possible only for a Kardashev Type II civilization. If it were a narrow beam signal focused on our Solar System, it would be of a power available to a Kardashev Type I civilization. The possibility of noise of one form or another cannot be ruled out, and researchers in Paris led by Jean Schneider are considering the possible microlensing of a background source by HD164595. But the signal is provocative enough that the RATAN-600 researchers are calling for permanent monitoring of this target."

US Patients Battle EpiPen Prices And Regulations By Shopping Online ( 394

"The incredible increase in the cost of EpiPens, auto-injectors that can stop life-threatening emergencies caused by allergic reactions, has hit home on Capitol Hill," reports CNN. Slashdot reader Applehu Akbar reports that the argument "has now turned into civil war in the US Senate": One senator's daughter relies on Epi-Pen, while another senator's daughter is CEO of Mylan, the single company that is licensed to sell these injectors in the US. On the worldwide market there is no monopoly on these devices... Is it finally time to allow Americans to go online and fill their prescriptions on the world market?
Time reports some patients are ordering cheaper EpiPens from Canada and other countries online, "an act that the FDA says is technically illegal and potentially dangerous." But the FDA also has "a backlog of about 4,000 generic drugs" awaiting FDA approval, reports PRI, noting that in the meantime prices have also increased for drugs treating cancer, hepatitis C, and high cholesterol. In Australia, where the drug costs just $38, one news outlet reports that the U.S. "is the only developed nation on Earth which allows pharmaceutical companies to set their own prices."

HAARP Holds Open House To Dispel Rumors Of Mind Control ( 148

An anonymous Slashdot reader writes: HAARP -- the former Air Force/Navy/DARPA research program in Alaska -- will host an open house Saturday where "We hope to show people that it is not capable of mind control and not capable of weather control and all the other things it's been accused of..." said Sue Mitchell, spokesperson for the geophysical institute at the University of Alaska. "We hope that people will be able to see the actual science of it." HAARP, which was turned over to The University of Alaska last August, has been blamed for poor crop yields in Russia, with conspiracy theorists also warning of "a super weapon capable of mind control or weather control, with enough juice to trigger hurricanes, tornadoes and earthquakes."

The facility's 180 high-frequency antennas -- spread across 33 acres -- will be made available for public tours, and there will also be interactive displays and an unmanned aircraft 'petting zoo'. The Alaska Dispatch News describes it as "one of the world's few centers for high-power and high-frequency study of the ionosphere... important because radio waves used for communication and navigation reflect back to Earth, allowing long-distance, short-wave broadcasting."


SpaceX Dragon Returns Home From ISS ( 55

An anonymous reader quotes a report from Florida Today: A SpaceX Dragon capsule that helped prepare the International Space Station for future commercial astronaut flights has returned to Earth after a stay of more than month-long mission. A robotic arm released the unmanned capsule packed with 3,000 pounds of cargo at 6:11 a.m. EDT, then fired thrusters several times to move a safe distance away from the station orbiting about 250 miles up. The departure began a less than six-hour journey that culminated in a Pacific Ocean splashdown at 11:47 a.m. EDT, about 300 miles southwest of Baja, California. The Dragon launched from Cape Canaveral early July 18 on a Falcon 9 rocket and berthed at the station two days later. Among the cargo brought back from space Friday were a dozen mice from a Japanese science experiment -- the first brought home alive in a Dragon. Samples from mice euthanized as part of an experiment by pharmaceutical company Eli Lilly also were on board. Results were returned from an experiment that studied the behavior of heart cells in microgravity, and from research into the composition of microbes in the human digestive system, NASA said. Findings from both could help keep astronauts healthy during deep space exploration missions. SpaceX plans to launch a Falcon 9 rocket from Cape Canaveral Air Force Station next Saturday, Sept. 3.

Amazon, NVIDIA and The CIA Want To Teach AI To Watch Us From Space ( 60

An anonymous reader quotes a report from MIT Technology Review: Satellite operator DigitalGlobe is teaming up with Amazon, the venture arm of the CIA, and NVIDIA to make computers watch the Earth from above and automatically map our roads, buildings, and piles of trash. MIT Technology Review reports: "In a joint project, DigitalGlobe today released satellite imagery depicting the whole of Rio de Janeiro to a resolution of 50 centimeters. The outlines of 200,000 buildings inside the city's roughly 1,900 square kilometers have been manually marked on the photos. The SpaceNet data set, as it is called, is intended to spark efforts to train machine-learning algorithms to interpret high-resolution satellite photos by themselves. DigitalGlobe says the SpaceNet data set should eventually include high-resolution images of half a million square kilometers of Earth, and that it will add annotations beyond just buildings. DigitalGlobe's data is much more detailed than publicly available satellite data such as NASA's, which typically has a resolution of tens of meters. Amazon will make the SpaceNet data available via its cloud computing service. Nvidia will provide tools to help machine-learning researchers train and test algorithms on the data, and CosmiQ Works, a division of the CIA's venture arm In-Q-Tel focused on space, is also supporting the project." "We need to develop new algorithms for this data," says senior vice president at DigitalGlobe, Tony Frazier. He goes on to say that health and aid programs are to benefit from software that is able to map roads, bridges and various other infrastructure. The CEO of Descartes Labs, Mark Johnson, a "startup that predicts crop yields from public satellite images," says the data that is collected "should be welcome to startups and researchers," according to MIT Technology Review. "Potential applications could include estimated economic output from activity in urban areas, or guiding city governments on how to improve services such as trash collections, he says."

NASA Astronaut Jeff Williams Sets New US Space Endurance Record With 521 Days ( 44

An anonymous reader quotes a report from CBS News: Space station commander Jeff Williams set a new U.S. space endurance record Wednesday, his 521st day in orbit over four missions, eclipsing the 520-day record set earlier this year by astronaut Scott Kelly at the end of his nearly one-year stay aboard the lab complex. Williams now moves up to 17th on the list of the world's most experienced astronauts and cosmonauts. The overall record is held by cosmonaut Gennady Padalka, who logged 878 days in orbit over five missions. Williams, Soyuz TMA-20M commander Alexey Ovchinin and flight engineer Oleg Skripochka were launched to the space station March 18. They plan to return to Earth Sept. 6 (U.S. time), landing in Kazakhstan to close out a 172-day mission. At landing, Williams will have logged 534 days aloft, moving him up to 14th on the space endurance list. Williams first flew in space in 2000 aboard the shuttle Atlantis, the third shuttle flight devoted to station assembly. He served as a flight engineer aboard the station in 2006 and completed a second long-duration stay in 2010, serving as a flight engineer and then commander of Expedition 22. "I wanted to congratulate you on passing me up here in total number of days in space," Kelly radioed Williams Wednesday. "It's great to see another record broken. [...] But I do have one question for you. And my question is, do you have another 190 days in you?" Kelly was referring to the time Williams' current mission would have to be extended to equal Kelly's U.S. single-flight record. Williams laughed, saying "190 days. That question's not for me, that's for my wife!"

Global Warming Started 180 Years Ago Near Beginning of Industrial Revolution, Says Study ( 695

New research led by scientists at the Australian National University's Research School of Earth suggests that humans first started to significantly change the climate in the 1830s, near the beginning of the Industrial Revolution. The findings have been published in the journal Nature, and "were based on natural records of climate variation in the world's oceans and continents, including those found in corals, ice cores, tree rings and the changing chemistry of stalagmites in caves." Sydney Morning Herald reports: "Nerilie Abram, another of the lead authors and an associate professor at the Australian National University's Research School of Earth Sciences, said greenhouse gas levels rose from about 280 parts per million in the 1830s to about 295 ppm by the end of that century. They now exceed 400 ppm. Understanding how humans were already altering the composition of the atmosphere through the 19th century means the warming is closer to the 1.5 to 2 degrees target agreed at last year's Paris climate summit than most people realize." "It was one of those moments where science really surprised us," says Abram. "But the results were clear. The climate warming we are witnessing today started about 180 years ago."

Apple Under Tim Cook: More Socially Responsible, Less Visionary ( 152

Let's talk about Apple, unarguably one of the most remarkable companies on the face of the earth. (Remarkable doesn't necessarily mean great -- it just means that the company is something worth making a remark). You can like it, or hate it, but you can simply not ignore Apple. But what's the occasion, you ask? It's been five years since Tim Cook took over as Apple CEO. (Editor's note: auto-playing video ahead, which may annoy you) Under his leadership, Apple has grown to become the world's most successful company, doubling the stock price and registering a staggering 84 percent growth in its net worth. Media outlets are abuzz with articles, analysis, and over-analysis of Tim Cook's Apple today. Some excerpts from a CNN article: Apple's culture has changed noticeably, both for the better and the worse. [...] If Jobs put a dent in the universe through Apple's coveted products, Cook is making his mark by highlighting the importance of social efforts: LGBT rights, philanthropy, corporate diversity, renewable energy and improving manufacturing conditions abroad. Under Cook's leadership, Apple finally began matching charitable contributions from employees, which had long been a sore spot for staff. Apple had 110,000 full-time employees as of the end of September 2015, nearly doubling from the 60,400 employees it reported having in September 2011, shortly after Cook took over, according to annual filings with the SEC. [...] There's now a feeling among some Apple insiders that the company is just running the same product playbook that Jobs created in his final years at the helm. "For four or five years, the playbook is the same that's been done," says Amit Sharma, a former Apple exec on the online store team. But, he adds, "just because everybody is looking for new doesn't mean it's not working."

Earth-Like Planet, With Ambitious Life Possibility, Found Orbiting the Star Next Door ( 218

There's another Earth out there. For real, this time. Astronomers announced on Wednesday that they had detected a planet orbiting Proxima Centauri, the closest neighbor to our solar system. Intriguingly, the planet is in the star's "Goldilocks zone," they said, a place that hints that it may not be too hot nor too cold. Which in turn means that liquid water could exist at the surface, and by extension, it raises the possibility of life. Nature reports:"The search for life starts now," says Guillem Anglada-Escude, an astronomer at Queen Mary University of London and leader of the team that made the discovery. Humanity's first chance to explore this nearby world may come from the recently announced Breakthrough Starshot initiative, which plans to build fleets of tiny laser-propelled interstellar probes in the coming decades. Travelling at 20% of the speed of light, they would take about 20 years to cover the 1.3 parsecs from Earth to Proxima Centauri. Proxima's planet is at least 1.3 times the mass of Earth. The planet orbits its red-dwarf star -- much smaller and dimmer than the Sun -- every 11.2 days. "If you tried to pick the type of planet you'd most want around the type of star you'd most want, it would be this," says David Kipping, an astronomer at Columbia University in New York City. "It's thrilling."Much about the planet is still unknown. Astronomers have some ideas about its size and distance from its parent star. Scientists say they are working off computer models that offer mere hints of what's possible. Also, there's no picture available for this planet as of yet.

NASA Reconnects With 'Lost' STEREO-B Satellite ( 107

NASA lost contact with its STEREO-B spacecraft twenty-two months ago during a routine 72-hour test. On Sunday, the spacecraft reconnected with NASA roughly 189 million miles away from Earth. While that would seem like a cause for celebration, "the very hard and scary work is just the beginning, says Stereo project scientist Joe Gurman, as the agency has to turn on the computer to learn more about the current state of the spacecraft -- a process that may make the craft lose contact with them again. Slashdot user bongey writes: NASA may have only two minutes or less to fix a STEREO-B satellite before the computer causes it to lose contact again. NASA lost contact with their STEREO-B satellite nearly twenty-two months ago when performing a routine test. NASA scientists are afraid to turn on the computer at this point because it may cause them to lose contact again. A more detailed technical summary can be found here. "We have something like two minutes between when STEREO-B receives the command to boot up one of its computers and when it starts doing what we don't want it to do," Gurman said. Business Insider writes, "Making matters worse, it takes about 20 seconds to send commands to the spacecraft -- a data rate that makes a dial-up modem seem lightning fast."

NanoRacks Plans To Turn Used Rocket Fuel Tanks Into Space Habitats ( 130

An anonymous reader writes from a report via IEEE Spectrum: A couple of weeks ago NASA announced it has committed $65 million to six companies over the course of two years for the purpose of developing and testing deep-space habitats that could be used for future missions to Mars. One of the six companies, called NanoRacks, is attempting to take empty fuel tanks from the upper stages of rockets and turn them into space habitats on-orbit. IEEE Spectrum reports: "A rocket like the the Atlas V, which can deliver payloads of nearly 19,000 kg to low Earth orbit, consists of three primary pieces: on the bottom, you've got the first stage booster, which consists of a huge engine and some big tanks holding kerosene fuel and oxidizer. Above that, there's the second stage, which consists of one or two smaller engines, a big tank for storing liquid hydrogen fuel, and a smaller tank for oxidizer. The payload, which is what all of the fuss is about, sits on top. The first stage launches the rocket off of the pad and continues firing for about four minutes. Meanwhile, the second stage fires up its own engine (or engines) to boost the payload the rest of the way into orbit. On the Atlas V, the second stage is called Centaur. Once Centaur gets its payload where it needs to go, it separates, and then suicides down into Earth's atmosphere. Getting a payload into space is so expensive because you have to build up this huge and complicated rocket, with engines and guidance systems and fuel tanks and stuff, and then you basically use it for like 15 minutes and throw it all away. But what about the second stage? You've got a whole bunch of hardware that made it to orbit, and when getting stuff to orbit costs something like $2,500 per kilogram, you then tell it to go it burn itself up in the atmosphere, because otherwise it's just useless space junk." NanoRacks thinks this is wasteful, so they want to turn these tanks into deep space habitats. IEEE notes that the hydrogen fuel tank on a Centaur upper stage has a diameter of over 4 meters, and an interior volume of 54 cubic meters, while the inflatable BEAM module that arrived at the ISS earlier this year has an interior volume of 16 cubic meters. For more details, IEEE Spectrum spoke with Jeff Manber, CEO of NanoRacks, and Mike Johnson, NanoRacks' Chief Designer. You can read their responses here.

Every Month This Year Has Been the Hottest In Recorded History ( 412

Slashdot reader iONiUM quotes an article from Vice that calls attention to the fact that record-setting temperatures in July are just part of the story: On Wednesday, the US National Oceanic and Atmospheric Administration announced that July was the hottest month ever recorded on our planet, since modern record-keeping began in 1880. NASA has reached the same conclusion. July smashed all previous records... "We should be absolutely concerned," [NOAA climatologist] Sanchez-Lugo said. "We need to look at ways to adapt and mitigate. If we don't, temperatures will continue to increase"...

But the truth is that record-breaking temperatures, month after month, year after year, are starting to look less like an exception, more like the norm.

In fact, CityLab reports that the earth has now experienced 14 consecutive months of unprecedented hotness. Although July stands out, Vice notes that "each consecutive month in 2016 has broken its own previous record (May was the hottest May, April the hottest April, etc.)..."

Eleven Reasons To Be Excited About The Future of Technology ( 282

Chris Dixon, an American internet entrepreneur and investor in a range of tech and media companies including Kickstarter and Foursquare has written an essay on Medium highlighting some of the reasons why we should be excited about the future of technology. The reasons he has listed are as follows: 1. Self-Driving Cars: Self-driving cars exist today that are safer than human-driven cars in most driving conditions. Over the next 3-5 years they'll get even safer, and will begin to go mainstream.
2. Clean Energy: Attempts to fight climate change by reducing the demand for energy haven't worked. Fortunately, scientists, engineers, and entrepreneurs have been working hard on the supply side to make clean energy convenient and cost-effective.
3. Virtual and Augmented Reality: Computer processors only recently became fast enough to power comfortable and convincing virtual and augmented reality experiences. Companies like Facebook, Google, Apple, and Microsoft are investing billions of dollars to make VR and AR more immersive, comfortable, and affordable.
4. Drones and Flying Cars: GPS started out as a military technology but is now used to hail taxis, get mapping directions, and hunt Pokemon. Likewise, drones started out as a military technology, but are increasingly being used for a wide range of consumer and commercial applications.
5. Artificial Intelligence: Artificial intelligence has made rapid advances in the last decade, due to new algorithms and massive increases in data collection and computing power.
6. Pocket Supercomputers for Everyone: By 2020, 80% of adults on earth will have an internet-connected smartphone. An iPhone 6 has about 2 billion transistors, roughly 625 times more transistors than a 1995 Intel Pentium computer. Today's smartphones are what used to be considered supercomputers.
7. Cryptocurrencies and Blockchains: Protocols are the plumbing of the internet. Most of the protocols we use today were developed decades ago by academia and government. Since then, protocol development mostly stopped as energy shifted to developing proprietary systems like social networks and messaging apps. Cryptocurrency and blockchain technologies are changing this by providing a new business model for internet protocols. This year alone, hundreds of millions of dollars were raised for a broad range of innovative blockchain-based protocols.
8. High-Quality Online Education: While college tuition skyrockets, anyone with a smartphone can study almost any topic online, accessing educational content that is mostly free and increasingly high-quality.
9. Better Food through Science: Earth is running out of farmable land and fresh water. This is partly because our food production systems are incredibly inefficient. It takes an astounding 1799 gallons of water to produce 1 pound of beef. Fortunately, a variety of new technologies are being developed to improve our food system.
10. Computerized Medicine: Until recently, computers have only been at the periphery of medicine, used primarily for research and record keeping. Today, the combination of computer science and medicine is leading to a variety of breakthroughs.
11. A New Space Age: Since the beginning of the space age in the 1950s, the vast majority of space funding has come from governments. But that funding has been in decline: for example, NASA's budget dropped from about 4.5% of the federal budget in the 1960s to about 0.5% of the federal budget today.


NASA: July 2016 Was Earth's Warmest Month On Record ( 271

mdsolar quotes a report from The Weather Channel: Copernicus Climate Change Service (C3S), operated by the European Centre for Medium-range Weather Forecasts (ECMWF), calculated the global average July temperature was nearly one-fifth of a degree Celsius higher than previous July temperature records set in 2015 and in 2009. July was also 0.55 degrees Celsius higher than the July average for 1981-2010. Compared to the July average, the south-central part of the United States including Texas and into northern Mexico were the most anomalously warm for North America. Globally, portions of western Russia and the Southern Ocean were warmest compared to average. In Russia, fires and an anthrax outbreak have been blamed on warmer than average temperatures. Each of the last 12 months has been the warmest on record for their respective months. This is due to a combination of global climate variability and human activity according to C3S. July is typically the warmest month of the year globally because the Northern Hemisphere has more land masses than the Southern Hemisphere. (NASA GISS Surface Temperature Analysis (GISTEMP) confirms today.)

Astronomers To Announce Discovery of a Nearby 'Earth-Like' Planet ( 347

astroengine quotes a report from Seeker: Scientists are preparing to unveil a new planet in our galactic neighborhood which is "believed to be Earth-like" and orbits its star at a distance that could favor life, German weekly Der Spiegel reported Friday. The exoplanet orbits a well-investigated star called Proxima Centauri, part of the Alpha Centauri star system, the magazine said, quoting anonymous sources.

"The still nameless planet is believed to be Earth-like and orbits at a distance to Proxima Centauri that could allow it to have liquid water on its surface -- an important requirement for the emergence of life," said the magazine.

It's orbiting our sun's nearest neighboring star -- just 4.25 light years away -- meaning it could someday be considered for the world's first interstellar mission.

Fourth SpaceX Rocket Successfully Landed on A Drone Ship ( 71

Saturday a SpaceX rocket completed the company's fourth successful landing at sea (watched by over 100,000 viewers on YouTube and Flickr). Saturday's landing means Elon Musk's company has now recovered more than half the rockets they've launched. An anonymous Slashdot reader quotes Saturday's report from The Verge: Tonight's landing was particularly challenging for SpaceX... The Falcon 9 had to carry its onboard satellite -- called JCSAT-16 -- into...a highly elliptical orbit that takes the satellite 20,000 miles out beyond Earth's surface. Getting to GTO requires a lot of speed and uses up a lot of fuel during take off, more so than getting to lower Earth orbit. That makes things difficult for the rocket landing afterward...there's less fuel leftover for the vehicle to reignite its engines and perform the necessary landing maneuvers.

CEO Elon Musk said the company is aiming to launch its first landed rocket sometime this fall...SpaceX's president, Gwynne Shotwell, estimates that reusing these landed Falcon 9 vehicles will lead to a 30 percent reduction in launch costs.

SpaceX named their drone ship "Of Course I Still Love You."
