Ever since astronomers started to detect planets beyond our solar system, they've been trying to find another world just like Earth. And few years ago, they announced that they'd found a planet that was the closest match yet -- Kepler-452b. Trouble is, some astronomers now say it's not possible to know for sure that this planet actually exists. From a report: "There's new information that we can now quantify which tells us something that we didn't know before," says Fergal Mullally, who used to be an astronomer on the science team for NASA's Kepler Space Telescope. In 2015, NASA declared that Kepler-452b was the first near-Earth-sized planet orbiting in the "habitable" zone around a star very similar to our sun. The space agency called it Earth's "bigger, older cousin," and scientists were so enthusiastic that one began quoting poetry at a news conference. The original science wasn't shoddy, Mullally says. It's just that, since then, researchers have learned more about the telescope's imperfections.

"A former paperboy from Wisconsin passionate about maps led the team in the Air Force responsible for designing the navigation system we use everyday," writes Slashdot reader dkatana. IoT Times reports: At the IEEE honors ceremony today in San Francisco, Bradford Parkinson, a retired Air Force colonel who spent his life between maps and navigation systems, will be awarded the 2018 IEEE Medal of Honor, "For fundamental contributions to and leadership in developing the design and driving the early applications of the Global Positioning System." The current Global Positioning System (GPS) did not exist until 1995, just 22 years ago, and the engineer who led the project for the U.S. Department of Defense (DOD) was Mr. Parkinson.

Parkinson, whose first job was delivering newspapers, had a passion for maps. He used those maps when canoeing to navigate the lakes and streams of Minnesota, aided by a hand compass. When he graduated from the U.S. Naval Academy in 1957 with a Bachelor of Science in Engineering, he joined the Air Force to study navigation systems. In 1960, when his superiors saw his engineering potential, they sent him to the Massachusetts Institute of Technology to pursue graduate studies. He became a protegee of Charles Stark (Doc) Draper, the father of inertial navigation, who was teaching at MIT at the time. Draper was the lead engineer developing the computer systems for NASA's Apollo program. [...] It was in 1972 when his path on inertial navigation collided with satellite systems. He had been recently promoted to colonel when he received a call from another colonel who was part of the Air Force inertial guidance "mafia." He moved to Los Angeles and joined the group, a bunch of Air Force engineers from MIT. Then Parkinson asked to work on the Air Force 621B program, the genesis of GPS.

An anonymous reader quotes a report from Ars Technica: Now that DeepMind has solved Go, the company is applying DeepMind to navigation. Navigation relies on knowing where you are in space relative to your surroundings and continually updating that knowledge as you move. DeepMind scientists trained neural networks to navigate like this in a square arena, mimicking the paths that foraging rats took as they explored the space. The networks got information about the rat's speed, head direction, distance from the walls, and other details. To researchers' surprise, the networks that learned to successfully navigate this space had developed a layer akin to grid cells. This was surprising because it is the exact same system that mammalian brains use to navigate. More DeepMind experiments showed that only the neural networks that developed layers that "resembled grid cells, exhibiting significant hexagonal periodicity (gridness)," could navigate more complicated environments than the initial square arena, like setups with multiple rooms. And only these networks could adjust their routes based on changes in the environment, recognizing and using shortcuts to get to preassigned goals after previously closed doors were opened to them. The study has been reported in the journal Science.

Two years ago, if you had asked experts to identify the most influential person in technology, you would have heard some familiar names: Jeff Bezos of Amazon, Alibaba's Jack Ma or Facebook's Mark Zuckerberg. Today there is a new contender: Masayoshi Son. The founder of SoftBank, a Japanese telecoms and internet firm, has put together an enormous investment fund that is busy gobbling up stakes in the world's most exciting young companies. The Vision Fund is disrupting both the industries in which it invests and other suppliers of capital [Editor's note: the link may be paywalled; an alternative source wasn't immediately available]. From a report: But even if the fund ends up flopping, it will have several lasting effects on technology investing. The first is that the deployment of so much cash now will help shape the industries of the future. Mr Son is pumping money into "frontier technologies" from robotics to the internet of things. He already owns stakes in ride-hailing firms such as Uber; in WeWork, a co-working company; and in Flipkart, an Indian e-commerce firm that was this week sold to Walmart. In five years' time the fund plans to have invested in 70-100 technology unicorns, privately held startups valued at $1bn or more. Its money, often handed to entrepreneurs in multiples of the amounts they initially demand and accompanied by the threat that the cash will go to the competition if they balk, gives startups the wherewithal to outgun worse-funded rivals. Mr Son's bets do not have to pay off for him to affect the race. Mr Son's second impact will be on the venture-capital industry. To compete with the Vision Fund's pot of moolah, and with the forays of other unconventional investors, incumbents are having to bulk up.

Junk food advertising could be banned from the entire Transport for London network under proposals announced by Mayor Sadiq Khan, as he tries to tackle rising levels of childhood obesity in the city. From a report: "I want to reduce the influence and pressure that can be put on children and families to make unhealthy choices," Khan said in a statement announcing the proposals to ban advertisements for unhealthy food and drink on London's trains, buses and bus shelters. The mayor also proposed a ban on new hot food takeaway stores opening within 400 meters of schools.

London has one of the highest childhood obesity rates in Europe -- nearly 40 percent of 10-11 year-olds in the capital are overweight or obese, according to the statement. Children from poorer areas are disproportionately affected by the "obesity epidemic," Khan said, adding that young people from Barking and Dagenham in East London are almost twice as likely to be overweight as children from the upmarket Richmond neighborhood.

Billly Gates shares a report: It was this time last year that Microsoft announced that it was bringing Ubuntu to the Windows Store (now the Microsoft Store), along with other Linux distributions. If you check out the app in the Store now though, you'll find that it only works on x64 devices, meaning that you can't run it on any of the new Windows 10 on ARM PCs. That's all about to change though. In a session at Microsoft's Build 2018 developer conference today called Windows 10 on ARM for Developers, the company showed off Ubuntu running on an ARM PC, with the app coming from the Microsoft Store. It will finally support ARM64 PCs, although x86 devices are still out of luck.

Malicious Android apps that have been previously reported to Google are showing up again on company's marquee Play Store with new names, security researchers are reporting. BleepingComputer: Seven of these apps have been "rediscovered," said Symantec in a report published yesterday. The company's experts say the author of the original malicious apps didn't do anything special, but only changed the app's names, without making modifications to the code, and re-uploaded the apps on the Play Store from a new developer account under a new name. Symantec says it detected seven of these re-uploaded apps on the Play Store, which it re-reported to Google's security team and had them taken down again.

An anonymous reader shares a report: Probing the bowels of what he believed to be North Korean hacking architecture, American cybersecurity researcher Darien Huss found an outlier: iPhone software. It appeared at first glance to be a fairly mundane program, a mobile device management (MDM) tool. Such apps are typically used for businesses to remotely monitor and control employees' phones. But, according to Huss, it's most likely one of, if not the only, example of North Korean spyware for Apple's smartphone.

It's unlikely the MDM app was anything other than malicious, said Huss, an employee of cybersecurity company Proofpoint. Tellingly, it was located on a server believed to contain other hacking tools, in particular those for Microsoft Windows, that he'd linked to one of the bigger North Korean hacking groups, the researcher explained to Forbes. If the iPhone tool is indeed a piece of spyware, Huss hasn't seen it used yet. He believes it's currently in development by that North Korean-linked hacker crew, though Proofpoint declined to provide additional details on his research.

Facebook is "very serious" about launching its own cryptocurrency, news outlet Cheddar reported Friday. It's not the first time the idea of a Facebook coin has been floated, but it seems more apparent now in wake of Facebook's reshuffled executive structure and newly formed blockchain group. From the report: Facebook started studying blockchain almost a year ago, when a member of its corporate development team, Morgan Beller, began looking at how the social platform could use the emerging technology. At the time, Beller was the only Facebook employee devoted to studying blockchain, the digital and decentralized ledger that underpins cryptocurrencies like Bitcoin and Ethereum. Her work was thrust into the spotlight this week when Facebook announced that the vice president in charge of the Messenger app, David Marcus, would lead a new team to "explore how to best leverage blockchain across Facebook, starting from scratch."

In a massive strike, the Federal Communications Commission issued a $120 million fine on a massive robocall spoofing operation it deemed a threat to public safety. From a report: The FCC announced Thursday morning that it would leverage the fine against Adrian Abramovich, a Miami man who the commission said made almost 100 million spoofed robocalls over a three-month period at the end of 2016. The FCC argued that Abramovich's operation made the phony calls to trick consumers into answering them and listening to his advertising messages. The fine was based on 80,000 spoofed calls the commission had verified.

A complaint filed by the FCC against Abramovich in June 2017 alleged he had broken the Truth in Caller ID Act -- which prohibits callers from falsifying caller ID information to disguise their identity with intent to harm or defraud -- in perpetrating "one of the largest -- and most dangerous -- illegal robocalling campaigns that the commission has ever investigated."

The Boring Company has made some pretty impressive strides in its relatively short existence. Elon Musk first shared his vision for the company in December 2016, promising to solve traffic woes with networks of tunnels for city centers. It is now adding the finishing touches to its first burrow. From a report: In a video shared on Instagram today, Musk showed what a trip through one of these tunnels would look like. He also declared the Boring Company's first tunnel under LA to be almost complete, and that "pending final regulatory approvals, we will be offering free rides to the public in a few months."

As federal crimes go, this one seems to have been ridiculously easy to pull off. From a report: Dushaun Henderson-Spruce submitted a U.S. Postal Service change of address form on Oct. 26, 2017, according to court documents. He requested changing a corporation's mailing address from an address in Atlanta to the address of his apartment on Chicago's North Side. The post office duly updated the address, and Henderson-Spruce allegedly began receiving the company's mail -- including checks. It went on for months. Prosecutors say he deposited some $58,000 in checks improperly forwarded to his address.

The corporation isn't named in the court documents, but the Chicago Tribune reports that it's the shipping company UPS. In a statement to NPR, UPS said it "was notified that some U.S. mail, intended for UPS employees at the company's headquarters address, was redirected by an unauthorized change of address by a third party. The U.S. Postal Service (USPS) corrected the issue and the USPS Postal Inspector is investigating the incident."

Paul Voosen, reporting for Science magazine: You can't manage what you don't measure. The adage is especially relevant for climate-warming greenhouse gases, which are crucial to manage -- and challenging to measure. In recent years, though, satellite and aircraft instruments have begun monitoring carbon dioxide and methane remotely, and NASA's Carbon Monitoring System (CMS), a $10-million-a-year research line, has helped stitch together observations of sources and sinks into high-resolution models of the planet's flows of carbon. Now, President Donald Trump's administration has quietly killed the CMS, Science has learned.

The move jeopardizes plans to verify the national emission cuts agreed to in the Paris climate accords, says Kelly Sims Gallagher, director of Tufts University's Center for International Environment and Resource Policy in Medford, Massachusetts. "If you cannot measure emissions reductions, you cannot be confident that countries are adhering to the agreement," she says. Canceling the CMS "is a grave mistake," she adds.

An anonymous reader shares a report: A remote, freezing, salt-spray lashed paradise for wildlife has been completely cleared of rats in the largest rodent eradication of all time, the South Georgia Heritage Trust (SGHT) announced this week. Rats are smart, adaptable, and hungry. For all these reasons, they can be incredibly voracious predators when people accidentally introduce them to remote islands, where the local animals lack evolved defenses to rodents. They have flourished even on an island as harsh and cold as South Georgia, which is so far south that it hosts penguins, elephant seals, and fur seals, as well as massive permanent glaciers.

"There are no trees, there are no bushes. All nest on the ground or underground in burrows," says Mike Richardson, Chairman of the SGHT Habitat Restoration Project Steering Committee. Such nests are easy pickings for rats. The rats -- brought to the island by whalers and sealers as early as the late 18th century -- ate the eggs and vulnerable chicks of seabirds, including albatrosses, skua, terns, and petrels. They also threatened two birds with extinction that are found nowhere else in the world: the South Georgia Pipit -- a tiny speckled songbird -- and the South Georgia Pintail, a brown duck.

The rat eradication was a massive, arduous undertaking, costing more than $13 million and taking nearly a decade. More than 300 metric tons of poison bait was dropped on the island by helicopter in three separate trips during the Austral Summers of 2010-2011, 2012-2013, and 2014-2015. Poisoned rats tend to head underground to die, Richardson says, limiting the damage caused to birds like gulls that might have otherwise eaten the poison-tainted carcasses.
