Big Hairy Ian shares a report from New Atlas: When the first manned mission to Mars sets out, it may be on the tail of an atomic rocket engine. The Space Race vintage technology could have a renaissance at NASA after the space agency's Marshall Space Flight Center in Huntsville, Alabama signed a contract with BWXT Nuclear Energy to develop updated Nuclear Thermal Propulsion (NTP) concepts and new fuel elements to power them.

Today, with NASA once again considering the challenges of sending astronauts to Mars, the nuclear option is back on the table as part of the agency's Game Changing Development program. Under this, NASA has awarded BMXT, which supplies nuclear fuel to the U.S. Navy, a $18.8-million contract running through September 30, 2019 to look into the possibility of developing a new engine using a new type of fuel. Unlike previous designs using highly enriched uranium, BMXT will study the use of Low-Enriched Uranium (LEU), which has less than 20 percent of fissile uranium 235. This will provide a number of advantages. Not only is it safer than the highly enriched fuel, but the security arrangements are less burdensome, and the handling regulations are the same as those of a university research reactor. If NASA determines next month that the LEU engine is feasible, the project will conduct testing and refine the manufacturing process of the Cermet fuel elements over the course of a year, with testing of the full-length Cermet fuel rods to be conducted at Marshall.

Slashdot reader Big Hairy Ian adds: "At the very least it looks much more feasible than Project Orion."

An anonymous reader quotes a report from The Verge: Islamic State allegedly used PayPal and fake eBay transactions to channel money to an operative in the U.S., The Wall Street Journal reports. The man who allegedly received the money was American citizen Mohamed Elshinawy, who was arrested last year in Maryland. The FBI claims that Elshinawy, in his early 30s, sold computer printers on eBay as a front in order to receive the payments through PayPal. The details have come to light because of a recently unsealed FBI affidavit, which alleges Elshinawy was part of a worldwide network that used such channels to fund ISIS. Elshinawy received $8,700 from ISIS, including five PayPal payments from senior ISIS official Siful Sujan through his technology company. Those funds were used to buy a laptop, a cellphone, and a VPN to communicate with IS, according to the affidavit. Sujan was killed in a drone strike in 2015. eBay told The Wall Street Journal it "has zero tolerance for criminal activities taking place on our marketplace." Meanwhile, a spokeswoman for PayPal said it "invests significant time and resources in working to prevent terrorist activity on our platform. We proactively report suspicious activities and respond quickly to lawful requests to support law enforcement agencies in their investigations."

Robotron23 writes: Vinod Khosla, a Silicon Valley venture capitalist, has lost his appeal to privatize Martins Beach -- a publicly-owned strip of coastline in California. Having previously fenced off the land in a bid to render the area private, Khosla has been ordered to restore access by a California court. Khosla had previously demanded the government pay him $30 million to reopen the gate to the beachfront. The law of California states that all beaches should be open to the public up to the "mean high tide line." "The decision this week, affirming a lower court ruling, stems from a lawsuit filed by the Surfrider Foundation, a not-for-profit group that says the case could have broader implications for beach access across the U.S.," reports The Guardian.

An anonymous reader quotes a report from Reuters: Netflix is in "active discussions" with Disney about keeping Marvel and "Star Wars" films after 2019, when new Disney and Pixar movies will stop appearing on the streaming service, a senior executive said late on Thursday. Disney announced on Tuesday that it was pulling new Disney and Pixar films from Netflix, starting with new releases in 2019. It will start putting the movies on a new Disney-branded online service that year. Disney Chief Executive Officer Bob Iger told analysts the company had not yet decided where it would distribute superhero films from Marvel Studios and movies from "Star Wars" producer Lucasfilm, which the company owns, at that time. Netflix is still in discussions with Disney about retaining rights to stream Marvel and Lucasfilm releases after 2019, Chief Content Officer Ted Sarandos told Reuters.

Last month, SoundCloud announced it was cutting about 40 percent of its staff in a cost-cutting move to help it compete against larger rivals like Spotify and Apple. One week after that announcement, TechCrunch published a report claiming "the layoffs only saved the company enough money to have runway 'until Q4' -- which begins in just 80 days." It now appears the company has closed the necessary funding round to keep itself afloat. TechCrunch reports: CEO Alex Ljung will step aside though remain chairman as former Vimeo CEO Kerry Trainor replaces him. Mike Weissman will become COO as SoundCloud co-founder and CTO Eric Wahlforss stays as chief product officer. New York investment bank Raine Group and Singapore's sovereign wealth fund Temasek have stepped in to lead the new Series F funding round of $169.5 million. SoundCloud declined to share the valuation or quantity of the new funding round. Yesterday, Axios reported the company was raising $169.5 million at a $150 million pre-money valuation. That's a steep decline in value from the $700 million it was valued at in previous funding rounds. The new Series F round supposedly gives Raine and Temasek liquidation preferences that override all previous investors, and the Series E investors are getting their preferences reduced by 40 percent. They're surely happy about that, but it's better than their investment vaporizing. Raine will get two board seats for bailing out SoundCloud, with partner and former music industry attorney Fred Davis, and the vice president who leads music investments, Joe Puthenveetil, taking those seats.

According to CNBC, Amazon is exploring a technology first developed for the U.S. military to produce tasty prepared meals that do not need refrigeration, as it looks for new ways to muscle into the $700 billion U.S. grocery business. From the report: The world's biggest online retailer has discussed selling ready-to-eat dishes such as beef stew and a vegetable frittata as soon as next year, officials at the startup firm marketing the technology told Reuters. The dishes would be easy to stockpile and ship because they do not require refrigeration and could be offered quite cheaply compared with take-out from a restaurant. Delivering meals would build on the company's AmazonFresh service, which has been delivering groceries to customers' homes for a decade. It could also complement Amazon's planned $13.7 billion purchase of Whole Foods Market and Amazon's checkout-free convenience store, which is in the test stage.

The pioneering food-prep tech, known as microwave assisted thermal sterilization, or MATS, was developed by researchers at Washington State University, and is being brought to market by a venture-backed startup called 915 Labs, based in Denver. The method involves placing sealed packages of food in pressurized water and heating them with microwaves for several minutes, according to 915 Labs. Unlike traditional processing methods, where packages are in pressure cookers for up to an hour until both bacteria and nutrients are largely gone, the dishes retain their natural flavor and texture, the company said. They also can sit on a shelf for a year, which would make them suitable for Amazon's storage and delivery business model.

An anonymous reader shares a report: While some people may point at The Emoji Movie as the root of all that is wrong with Hollywood, The Wall Street Journal reports that the problem goes much deeper than a single misfire featuring Patrick Stewart as a poop emoji. WSJ reports that movie attendance has dropped by 5%, compared with the same period in 2016, and revenues are down, too, dipping just 2.9%, thanks to higher ticket prices making up for the lack of ticket sales. On Aug. 2, AMC shares dropped 27% in one day, the WSJ reports. While films like Beauty and the Beast, Wonder Woman, and Get Out fared well at the box office, they were the anomalies in a year full of box office disappointments. Instead of giving moviegoers more badass female leads and genre-bending horror films, Hollywood keeps throwing gobs of money at an unwanted fifth installment of Pirates of the Caribbean, more Transformers movies, and putting $175 million into King Arthur: Legend of the Sword, and then clutching their pearls in shock that no one wanted to see them.

An anonymous reader quotes a report from The Verge: You'll have two extra weeks to file your thoughts with the FCC on its plan to get rid of net neutrality. The proposal's comment period was originally scheduled to end next week, on August 16th, but the commission just pushed the date out to August 30th. The extension was granted in response to 10 groups asking for more time to respond. They had been looking for an additional eight weeks, but the commission said an additional two weeks would be more in line with the type of extensions granted in the past. The commission didn't signal that disruptions to its filing system, caused by an apparent DDOS attack, factored into the decision at all. Granting a two week extension gives people more time to file "reply comments," which are meant to respond to what people filed during the first phase of the comment period, which closed in July. That comment period had been much longer than usual, because the commission released the proposal a month before it was voted on.

Jordan Pearson, writing for Motherboard: Satoshi Nakamoto is Bitcoin's anonymous creator and absentee head of state. In the years since she (or he, or they) disappeared into the ether and left the technology in the hands of a few high-profile developers, Nakamoto's words have become nigh-gospel for some in the Bitcoin world. On Friday, a user going by "CipherionX" on the Bitcointalk forum published five emails allegedly between Satoshi Nakamoto and former Bitcoin developer Mike Hearn. In an email to Motherboard, Hearn confirmed that he shared the emails with the user. While Hearn himself, who was one of the earliest Bitcoin developers, has previously quoted most of the juicy bits from his correspondence with Nakamoto, it appears to be the first time much of the material has been shared in full. None of the emails are included on a popular database of Nakamoto's writings collected from old emails and forum posts.

In an exclusive Wall Street Journal post, the engineer responsible for the anti-diversity "Google manifesto," James Damore, explains why he was fired by the company: I was fired by Google this past Monday for a document that I wrote and circulated internally raising questions about cultural taboos and how they cloud our thinking about gender diversity at the company and in the wider tech sector. I suggested that at least some of the male-female disparity in tech could be attributed to biological differences (and, yes, I said that bias against women was a factor too). Google Chief Executive Sundar Pichai declared that portions of my statement violated the company's code of conduct and "cross the line by advancing harmful gender stereotypes in our workplace." My 10-page document set out what I considered a reasoned, well-researched, good-faith argument, but as I wrote, the viewpoint I was putting forward is generally suppressed at Google because of the company's "ideological echo chamber." My firing neatly confirms that point. How did Google, the company that hires the smartest people in the world, become so ideologically driven and intolerant of scientific debate and reasoned argument? [...]

In my document, I committed heresy against the Google creed by stating that not all disparities between men and women that we see in the world are the result of discriminatory treatment. When I first circulated the document about a month ago to our diversity groups and individuals at Google, there was no outcry or charge of misogyny. I engaged in reasoned discussion with some of my peers on these issues, but mostly I was ignored. Everything changed when the document went viral within the company and the wider tech world. Those most zealously committed to the diversity creed -- that all differences in outcome are due to differential treatment and all people are inherently the same -- could not let this public offense go unpunished. They sent angry emails to Google's human-resources department and everyone up my management chain, demanding censorship, retaliation and atonement. Upper management tried to placate this surge of outrage by shaming me and misrepresenting my document, but they couldn't really do otherwise: The mob would have set upon anyone who openly agreed with me or even tolerated my views. When the whole episode finally became a giant media controversy, thanks to external leaks, Google had to solve the problem caused by my supposedly sexist, anti-diversity manifesto, and the whole company came under heated and sometimes threatening scrutiny.

An anonymous reader shares a report: A trio of MIT researchers recently tackled a tricky vehicle-routing problem when they set out to improve the efficiency of the Boston Public Schools bus system. Last year, more than 30,000 students rode 650 buses to 230 schools at a cost of $120 million. In hopes of spending less this year, the school system offered $15,000 in prize money in a contest that challenged competitors to reduce the number of buses. The winners -- Dimitris Bertsimas, co-director of MIT's Operations Research Center and doctoral students Arthur Delarue and Sebastien Martin -- devised an algorithm that drops as many as 75 bus routes. The school system says the plan, which will eliminate some bus-driver jobs, could save up to $5 million, 20,000 pounds of carbon emissions and 1 million bus miles (Editor's note: the link could be paywalled; alternative source). The computerized algorithm runs in about 30 minutes and replaces a manual system that in the past has taken transportation staff several weeks to complete. "They have been doing it manually many years," Dr. Bertsimas said. "Our whole running time is in minutes. If things change, we can re-optimize." The task of plotting school-bus routes resembles the classic math exercise known as the Traveling Salesman Problem, where the goal is to find the shortest path through a series of cities, visiting each only once, before returning home.

Zaria Gorvett, writing for BBC: In the middle of a Russian swampland, not far from the city of St Petersburg, is a rectangular iron gate. Beyond its rusted bars is a collection of radio towers, abandoned buildings and power lines bordered by a dry-stone wall. This sinister location is the focus of a mystery which stretches back to the height of the Cold War. It is thought to be the headquarters of a radio station, "MDZhB", that no-one has ever claimed to run. Twenty-four hours a day, seven days a week, for the last three-and-a-half decades, it's been broadcasting a dull, monotonous tone. Every few seconds it's joined by a second sound, like some ghostly ship sounding its foghorn. Then the drone continues. Once or twice a week, a man or woman will read out some words in Russian, such as "dinghy" or "farming specialist". And that's it. Anyone, anywhere in the world can listen in, simply by tuning a radio to the frequency 4625 kHz. It's so enigmatic, it's as if it was designed with conspiracy theorists in mind. Today the station has an online following numbering in the tens of thousands, who know it affectionately as "the Buzzer." It joins two similar mystery stations, "the Pip" and the "Squeaky Wheel." As their fans readily admit themselves, they have absolutely no idea what they are listening to.

An astronaut wandering the moon next year could use a smartphone to call home. If everything goes according to a plan, that is. A German startup is preparing to set up the first telecommunication infrastructure on the lunar surface. From a report: The German company Part Time Scientists, which originally competed for the Google Lunar X Prize race to the moon, plans to send a lander with a rover in late 2018 to visit the landing site of Apollo 17. (Launched in 1972, this was NASA's final Apollo mission to the moon.) Instead of using a complex dedicated telecommunication system to relay data from the rover to the Earth, the company will rely on LTE technology -- the same system used on Earth for mobile phone communications. "We are cooperating with Vodafone in order to provide LTE base stations on the moon," Karsten Becker, who heads embedded electronics development and integration for the startup, told Space.com. "What we are aiming to do is to provide commercial service to bring goods to the moon and also to provide services on the surface of the moon," Becker added.
