Rocket Lab Unveils "Electric" Rocket Engine - New submitter Adrian Harvey writes The New Zealand based commercial space company Rocket Lab has unveiled their new rocket engine which the media is describing as battery-powered. It still uses rocket fuel, of course, but has an entirely new propulsion cycle which uses electric motors to drive its turbopumps. To add to the interest over the design, it uses 3D printing for all its primary components. First launch is expected this year, with commercial operations commencing in 2016.

Can High Intelligence Be a Burden Rather Than a Boon? - HughPickens.com writes David Robson has an interesting article at BBC on the relationship between high intelligence and happiness. "We tend to think of geniuses as being plagued by existential angst, frustration, and loneliness," writes Robson. Think of Virginia Woolf, Alan Turing, or Lisa Simpson – lone stars, isolated even as they burn their brightest." As Ernest Hemingway wrote: "Happiness in intelligent people is the rarest thing I know." The first steps to studying the question were taken in 1926 when psychologist Lewis Terman decided to identify and study a group of gifted children. Terman selected 1,500 pupils with an IQ of 140 or more – 80 of whom had IQs above 170. Together, they became known as the "Termites", and the highs and lows of their lives are still being studied to this day. "As you might expect, many of the Termites did achieve wealth and fame – most notably Jess Oppenheimer, the writer of the classic 1950s sitcom I Love Lucy. Indeed, by the time his series aired on CBS, the Termites' average salary was twice that of the average white-collar job. But not all the group met Terman's expectations – there were many who pursued more "humble" professions such as police officers, seafarers, and typists. For this reason, Terman concluded that "intellect and achievement are far from perfectly correlated". Nor did their smarts endow personal happiness. Over the course of their lives, levels of divorce, alcoholism and suicide were about the same as the national average." According to Robson, one possibility is that knowledge of your talents becomes something of a ball and chain. During the 1990s, the surviving Termites were asked to look back at the events in their 80-year lifespan. Rather than basking in their successes, many reported that they had been plagued by the sense that they had somehow failed to live up to their youthful expectations (PDF).

Kingston HyperX Predator SSD Takes Gumstick M.2 PCIe Drives To 1.4GB/sec - MojoKid writes Kingston recently launched their HyperX Predator PCIe SSD that is targeted at performance-minded PC enthusiasts but is much less expensive than enterprise-class PCIe offerings that are currently in market. Kits are available in a couple of capacities and form factors at 240GB and 480GB. All of the drives adhere to the 80mm M.2 2280 "gumstick" form factor and have PCIe 2.0 x4 connections, but are sold both with and without a half-height, half-length adapter card, if you'd like to drop it into a standard PCI Express slot. At the heart of the Kingston HyperX Predator is Marvell's latest 88SS9293 controller. The Marvell 88SS9293 is paired to a gigabyte of DDR3 memory and Toshiba A19 Toggle NAND. The drives are rated for read speeds up to 1.4GB/s and writes of 1GB/s and 130 – 160K random 4K IOPS. In the benchmarks, the 480GB model put up strong numbers. At roughly $1 per GiB, the HyperX Predator is about on par with Intel's faster SSD 750, but unlike Intel's new NVMe solution, the Kingston drive will work in all legacy platforms as well, not just Z97 and X99 boards with a compatible UEFI BIOS.

Hacked Sony Emails Reveal That Sony Had Pirated Books About Hacking - An anonymous reader writes Sony has done a lot of aggressive anti-piracy work in their time, which makes it that much funnier that pirated ebooks were found on their servers from the 2014 hacks that just went on to WikiLeaks. Better yet, the pirated books are educational books about hacking called "Inside Cyber Warfare" and "Hacking the Next Generation" from O'Reilly publishers.

Google Ready To Unleash Thousands of Balloons In Project Loon - jfruh writes Google has figured out how to produce an Internet-broadcast balloon in a few hours, and is on the verge of unleashing Project Loon onto the world. The project, which will work with ISPs to beam LTE cellular signals to remote regions that don't have Internet access, will be working with local ISPs rather than selling broadband directly to customers.

The Origin of the First Light In the Universe - StartsWithABang writes Before there were planets, galaxies, or even stars in the Universe, there really was light. We see that light, left over today, in the form of the Cosmic Microwave Background, or the remnant glow from the Big Bang. But these photons outnumber the matter in our Universe by more than a-billion-to-one, and are the most numerous thing around. So where did they first come from? Science has the answer.

Google Adds Handwriting Input To Android - BarbaraHudson writes: The Reg is reporting on the release of Google Handwriting Input for Android smartphones and tablets: "The Chocolate Factory's research arm says handwriting recognition is needed because touchscreen keyboards remain modestly effective and while 'Voice input is an option, but there are situations where it is not feasible, such as in a noisy environment or during a meeting." The Google Research Blog notes that it allows recognition both on-device and in the cloud (by tapping on the cloud icon) in any Android app. It works as advertised on my smartphone, so now I can type, speak, or scribble my searches, texts, etc.

Incorrectly Built SLS Welding Machine To Be Rebuilt - schwit1 writes A giant welding machine, built for NASA's multi-billion dollar Space Launch System (SLS), has to be taken apart and rebuilt because the contractor failed to reinforce the floor, as required, prior to construction: "Sweden's ESAB Welding & Cutting, which has its North American headquarters in Florence, South Carolina, built the the roughly 50-meter tall Vertical Assembly Center as a subcontractor to SLS contractor Boeing at NASA's Michoud Assembly Facility in New Orleans. ESAB was supposed to reinforce Michoud's floor before installing the welding tool, but did not, NASA SLS Program Manager Todd May told SpaceNews after an April 15 panel session during the 31st Space Symposium here. As a result, the enormous machine leaned ever so slightly, cocking the rails that guide massive rings used to lift parts of the 8.4-meter-diameter SLS stages The rings wound up 0.06 degrees out of alignment, which may not sound like much, "but when you're talking about something that's 217 feet [66.14 meters] tall, that adds up," May said. Asked why ESAB did not reinforce the foundation as it was supposed to, May said only it was a result of "a miscommunication between two [Boeing] subcontractors and ESAB." It is baffling how everyone at NASA, Boeing, and ESAB could have forgotten to do the reinforcing, even though it was specified in the contract. It also suggests that the quality control in the SLS rocket program has some serious problems.

Columbia University Doctors Ask For Dr. Mehmet Oz's Dismissal - circletimessquare writes Dr. Mehmet Oz serves as vice chairman of Columbia University Medical Center's department of surgery. He is a respected cardiothoracic surgeon but his television show has been accused of pushing snake oil. Now other doctors at Columbia University want Dr. Oz kicked off the medical school faculty. Dr. Oz has responded on his Facebook account: "I bring the public information that will help them on their path to be their best selves. We provide multiple points of view, including mine which is offered without conflict of interest. That doesn't sit well with certain agendas which distort the facts. For example, I do not claim that GMO foods are dangerous, but believe that they should be labeled like they are in most countries around the world." In their letter, the doctors accuse Dr. Oz of quackery: "Dr. Oz has repeatedly shown disdain for science and for evidence-based medicine, as well as baseless and relentless opposition to the genetic engineering of food crops. Worst of all, he has manifested an egregious lack of integrity by promoting quack treatments and cures in the interest of personal financial gain."

Drought and Desertification: How Robots Might Help - Hallie Siegel writes Groundwater levels in California's Central Valley are down to historic lows and reservoirs have been depleted following four consecutive years of severe drought in the state. California is set to introduce water rationing in the coming weeks, and though the new rationing rules will focus on urban areas and not farms for the time being, they serve as a warning bell to farmers who will inevitably need to adapt to the effects of climate change on food production. John Payne argues that long term solutions are needed to help make agriculture drought resistant and looks at some of the ways that robotics might help.

John Gruber On Third-party Apple Watch Apps: They Suck and Are Really Slow - An anonymous reader writes During this week's episode of John Gruber's podcast, The Talk Show, Gruber sat down with Joanna Stern of the Wall Street Journal to talk all things Apple Watch. About two hours and 9 minutes into the podcast, both Gruber and Stern began lamenting the poor performance they saw with third-party Apple Watch apps. 'It makes me question whether there should be third party apps for it at all yet,' Gruber noted. The pair also took umbrage with what they perceived to be a poor design choice for the Apple Watch app screen, with both noting that the app icons were far too small to be practical.

John Hawley Talks About UAV Controls (Video) - John 'Warthog9' Hawley was the boss sysadmin on kernel.org before he jumped to Intel in April, 2014, as an open hardware technical evangelist. He last showed up on Slashdot in June, 2014, with his Dr. Who-inspired Robot K-9. Now he's talking about flight computers for quadcopters, specifically ones based on MinnowBoards. Last month (April 2015) he was speaking at the Embedded Linux Conference + Android Builders Summit. That's where he and Timothy Lord had this conversation about flight controllers for UAVs, which makes it a fitting sequel to yesterday's video, which was also about controlling drones with real-time Linux.
