An anonymous reader writes: You may recall Cody Wilson as the man behind the world's first 3D-printed gun. He built a company behind the ideals of DIY gun-making, and now he's come back with another device: the "Ghost Gunner," a CNC mill designed to create the lower receiver of an AR-15 rifle. "That simple chunk of metal has become the epicenter of a gun control firestorm. A lower receiver is the body of the gun that connects its stock, barrel, magazine and other parts. As such, it's also the rifle's most regulated element. Mill your own lower receiver at home, however, and you can order the rest of the parts from online gun shops, creating a semi-automatic weapon with no serial number, obtained with no background check, no waiting period or other regulatory hurdles. Some gun control advocates call it a "ghost gun." Selling that untraceable gun body is illegal, but no law prevents you from making one." Wilson's goal is still to render government gun regulation useless, even as debate rages on banning this kind of manufacturing.Read Replies (0)

An anonymous reader writes: In 2000, NASA began taking satellite images of the Aral Sea in central Asia, which was once the fourth-largest inland lake in the world. At that time, there was an expansive eastern basin, and smaller basins to the north and west. In images recorded just last week, we see that the eastern basin is completely gone, and the western basin just a thin strip of water. The local fishing industry has been devastated, old ship graveyards now rest on dry ground, and salt-heavy sand is being blown around the region, causing health issues.
Most of the lake's decline is attributable to human intervention: "In the 1950s, two of the region's major rivers – the Amu Darya and and the Syr Darya – were diverted by the Soviet government to provide irrigation for cotton production in Uzbekistan and Turkmenistan, starving the Aral. It has been diminishing ever since, with the sea level dropping 16 meters between 1960 and 1996, according to the World Bank. Water levels are believed to be down to less than 10 per cent of what they were five decades ago." Low levels of rain and snow didn't help.Read Replies (0)

An anonymous reader writes: Elon Musk's ambitions for SpaceX keep getting bigger. First he wanted to make the trip to Mars affordable, then he wanted to establish a city-sized colony, and now he's got his eye on the future of humanity. Musk says we need a million people on Mars to form a "sustainable, genetically diverse civilization" that can survive as humanity's insurance policy. He continued, "Even at a million, you're really assuming an incredible amount of productivity per person, because you would need to recreate the entire industrial base on Mars. You would need to mine and refine all of these different materials, in a much more difficult environment than Earth. There would be no trees growing. There would be no oxygen or nitrogen that are just there. No oil." How fast could we do it? Within a century, once the spacecraft reusability problem is solved. "Excluding organic growth, if you could take 100 people at a time, you would need 10,000 trips to get to a million people. But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more like 100,000 trips. And we're talking 100,000 trips of a giant spaceship."Read Replies (0)

sends this article from New Scientist:Hong Kong's mass protest is networked. Activists are relying on a free app that can send messages without any cellphone connection. Since the pro-democracy protests turned ugly over the weekend, many worry that the Chinese government would block local phone networks. In response, activists have turned to the FireChat app to send supportive messages and share the latest news. On Sunday alone, the app was downloaded more than 100,000 times in Hong Kong, its developers said. FireChat relies on "mesh networking," a technique that allows data to zip directly from one phone to another via Wi-Fi or Bluetooth. Ordinarily, if two people want to communicate this way, they need to be fairly close together. But as more people join in, the network grows and messages can travel further. Mesh networks can be useful for people who are caught in natural disasters or, like those in Hong Kong, protesting under tricky conditions. FireChat came in handy for protesters in Taiwan and Iraq this year."Read Replies (0)

Timothy Lord met Joey Hudy
at an Intel Dev Forum. Joey is possibly the youngest intern Intel has ever hired
, but he's made a big splash in the 'Maker world'
, so having him around is probably worth it for the PR value alone. Joey is obviously pretty bright -- he's been called one of the 10 smartest kids in the world
-- but let's face it: he's had a lot of luck to help him along. Let's face it: Not many high school kids get invited to White House science fairs and demonstrate their air cannons to the president

An anonymous reader sends news that the CDC has confirmed the first case of Ebola diagnosed on U.S. soil
.An unnamed patient at Texas Health Presbyterian Hospital of Dallas was placed in isolation while awaiting test results for the dreaded virus. Apparently, the patient had traveled recently to a West African country, where the disease is spreading, and later developed symptoms that suggested Ebola. A blood specimen from the patient was sent to Centers for Disease Control and Prevention in Atlanta, a testing process that can take 24 to 48 hours to confirm an Ebola infection — or not. The results came back about 3:32 p.m.
In other Ebola news, outbreaks in Nigeria and Senegal appear to be completely contained

Microsoft Announces Windows 10

Today at a press conference in San Francisco, Microsoft announced the new version of their flagship operating system, called Windows 10. (Yes, t-e-n. I don't know.
) With the new version of the operating system, they'll be unifying the application platform for all devices
: desktops, laptops, tablets, and phones. As early leaks showed, the Start Menu is back
— it's a hybrid of old and new, combining a list of applications with a small group of resizable tiles
that can include widgets. Metro-style apps can now each operate inside their own window. There's a new, multiple-desktop feature, which power users have been demanding for years, and also a feature that lets users easily grab objects from one desktop and transfer it to another. The Technical Preview builds for desktops and laptops will be available tomorrow through the Windows Insider Program. They're requesting feedback from customers. Windows 10 will launch in late 2015.Read Replies (0)
