FarnsworthG writes: A multi-billion-dollar Army project will soon be able to track nearly everything within 340 miles when an 80-yard-long blimp is hoisted into the air over Maryland. Way to be subtle, guys. From the article: "Technically considered aerostats, since they are tethered to mooring stations, these lighter-than-air vehicles will hover at a height of 10,000 feet just off Interstate 95, about 45 miles northeast of Washington, D.C., and about 20 miles from Baltimore. That means they can watch what’s happening from North Carolina to Boston, or an area the size of Texas."

from the all-the-platters dept.
Esra Erimez writes: Backblaze is transitioning from using 4 TB hard drives to 6 TB hard drives in the Storage Pods they will be deploying over the coming months. With over 10,000 hard drives, the choice of which 6TB hard drive to use is critical. They deployed 45 and tested Western Digital (WD60EFRX) and Seagate (STBD6000100) hard drives into two pods that were identical in design and configuration except for the hard drives used.

New Cargo Ship Is 488 Meters Long 106

Posted by Soulskill
from the go-big-or-go-home dept.
An anonymous reader writes: The BBC reports on the construction of Prelude, a new ship that will be the world's longest vessel. It is 488 meters long and 74 meters wide, built with 260,000 tons of steel and displacing five times as much water as an aircraft carrier. Its purpose is to carry an entire natural gas processing plant as it sits over a series of wells 100 miles off the coast of Australia. Until now, it hasn't been practical to move gas that comes out of the wells with ships. The gas occupies too much volume, so it is generally piped to a facility on shore where it is processed and then shipped off to energy-hungry markets. But the Prelude can purify and chill the gas, turning it into a liquid and reducing its volume by a factor of 600. It will offload this liquid to smaller (but still enormous) carrier ships for transport.

Sony Leaks Reveal Hollywood Is Trying To Break DNS 349

from the scorched-net-policy dept.
schwit1 sends this report from The Verge: Most anti-piracy tools take one of two paths: they either target the server that's sharing the files (pulling videos off YouTube or taking down sites like The Pirate Bay) or they make it harder to find (delisting offshore sites that share infringing content). But leaked documents reveal a frightening line of attack that's currently being considered by the MPAA: What if you simply erased any record that the site was there in the first place? To do that, the MPAA's lawyers would target the Domain Name System that directs traffic across the internet.

The tactic was first proposed as part of the Stop Online Piracy Act (SOPA) in 2011, but three years after the law failed in Congress, the MPAA has been looking for legal justification for the practice in existing law and working with ISPs like Comcast to examine how a system might work technically. If a takedown notice could blacklist a site from every available DNS provider, the URL would be effectively erased from the internet. No one's ever tried to issue a takedown notice like that, but this latest memo suggests the MPAA is looking into it as a potentially powerful new tool in the fight against piracy.

NASA Study Proposes Airships, Cloud Cities For Venus Exploration 182

from the billy-dee-williams-volunteers-to-lead dept.
An anonymous reader writes: IEEE Spectrum reports on a study out of NASA exploring the idea that manned missions to Venus are possible if astronauts deploy and live in airships once they arrive. Since the atmospheric pressure at the surface is 92 times that of Earth, and the surface temperate is over 450 degrees C, the probes we've sent to Venus haven't lasted long. The Venera 8 probe sent back data for only 50 minutes after landing. Soviet missions in 1985 were able to get much more data — 46 hours worth — by suspending their probes from balloons. The new study refines that concept: "At 50 kilometers above its surface, Venus offers one atmosphere of pressure and only slightly lower gravity than Earth. Mars, in comparison, has a "sea level" atmospheric pressure of less than a hundredth of Earth's, and gravity just over a third Earth normal. The temperature at 50 km on Venus is around 75 C, which is a mere 17 degrees hotter than the highest temperature recorded on Earth.

The defining feature of these missions is the vehicle that will be doing the atmospheric exploring: a helium-filled, solar-powered airship. The robotic version would be 31 meters long (about half the size of the Goodyear blimp), while the crewed version would be nearly 130 meters long, or twice the size of a Boeing 747. The top of the airship would be covered with more than 1,000 square meters of solar panels, with a gondola slung underneath for instruments and, in the crewed version, a small habitat and the ascent vehicle that the astronauts would use to return to Venus's orbit, and home."

New AP Course, "Computer Science Principles," Aims To Make CS More Accessible 191

Posted by Soulskill
from the broadening-the-base dept.
theodp writes: "CS Principles," explains the intro to a Microsoft Research talk on a new Computer Science Toolkit and Gaming Course, "is a new AP course being piloted across the country and by making it more accessible to students we can help increase diversity in computing." Towards this end, Microsoft has developed "a middle school computing toolkit, and a high school CS Principles & Games course." These two projects were "developed specifically for girls," explains Microsoft, and are part of the corporation's Big Dream Movement for girls, which is partnering with the UN, White House, NSF, EU Commission, and others. One of Microsoft's particular goals is to "reach every individual girl in her house." According to a document on its website, Microsoft Research's other plans for Bridging the Gender Gap in computing include a partnership with the University of Wisconsin "to create a girls-only computer science Massive Open Online Course (MOOC)."

A New Law For Superconductors 52

Posted by Soulskill
from the radar-enforced dept.
TaleSlinger sends word of a newly-discovered "mathematical relationship — between material thickness, temperature, and electrical resistance — that appears to hold in all superconductors." The work (abstract), led by Yachin Irvy, comes out of MIT's Research Laboratory of Electronics. Researchers found that a particular superconductor (niobium nitride) didn't fit earlier models estimating the temperature at which it changes from normal conductivity to superconductivity. So the researchers conducted a series of experiments in which they held constant either thickness or “sheet resistance,” the material’s resistance per unit area, while varying the other parameter; they then measured the ensuing changes in critical temperature. A clear pattern emerged: Thickness times critical temperature equaled a constant — call it A — divided by sheet resistance raised to a particular power — call it B. ... The other niobium nitride papers Ivry consulted bore out his predictions, so he began to expand to other superconductors. Each new material he investigated required him to adjust the formula’s constants — A and B. But the general form of the equation held across results reported for roughly three dozen different superconductors.

SpaceX To Attempt Falcon 9 Landing On Autonomous Spaceport Drone Ship 79

Posted by Soulskill
from the good-luck dept.
An anonymous reader writes: SpaceX has announced that at the conclusion of its next rocket flight, it will attempt a precision landing of its Falcon 9 first stage onto an autonomous ocean platform. They say the odds of success aren't great, but it's the beginning of their work to make this a reality. Quoting: "At 14 stories tall and traveling upwards of 1300 m/s (nearly 1 mi/s), stabilizing the Falcon 9 first stage for reentry is like trying to balance a rubber broomstick on your hand in the middle of a wind storm. To help stabilize the stage and to reduce its speed, SpaceX relights the engines for a series of three burns.

The first burn—the boostback burn—adjusts the impact point of the vehicle and is followed by the supersonic retro propulsion burn that, along with the drag of the atmosphere, slows the vehicle's speed from 1300 m/s to about 250 m/s. The final burn is the landing burn, during which the legs deploy and the vehicle's speed is further reduced to around 2 m/s. ... To complicate matters further, the landing site is limited in size and not entirely stationary. The autonomous spaceport drone ship is 300 by 100 feet, with wings that extend its width to 170 feet. While that may sound huge at first, to a Falcon 9 first stage coming from space, it seems very small. The legspan of the Falcon 9 first stage is about 70 feet and while the ship is equipped with powerful thrusters to help it stay in place, it is not actually anchored, so finding the bullseye becomes particularly tricky."

Economists Say Newest AI Technology Destroys More Jobs Than It Creates 571

Posted by Soulskill

HughPickens.com writes: Claire Cain Miller notes at the NY Times that economists long argued that, just as buggy-makers gave way to car factories, technology used to create as many jobs as it destroyed. But now there is deep uncertainty about whether the pattern will continue, as two trends are interacting. First, artificial intelligence has become vastly more sophisticated in a short time, with machines now able to learn, not just follow programmed instructions, and to respond to human language and movement. At the same time, the American work force has gained skills at a slower rate than in the past — and at a slower rate than in many other countries. Self-driving vehicles are an example of the crosscurrents. Autonomous cars could put truck and taxi drivers out of work — or they could enable drivers to be more productive during the time they used to spend driving, which could earn them more money. But for the happier outcome to happen, the drivers would need the skills to do new types of jobs.

When the University of Chicago asked a panel of leading economists about automation, 76 percent agreed that it had not historically decreased employment. But when asked about the more recent past, they were less sanguine. About 33 percent said technology was a central reason that median wages had been stagnant over the past decade, 20 percent said it was not and 29 percent were unsure. Perhaps the most worrisome development is how poorly the job market is already functioning for many workers. More than 16 percent of men between the ages of 25 and 54 are not working, up from 5 percent in the late 1960s; 30 percent of women in this age group are not working, up from 25 percent in the late 1990s. For those who are working, wage growth has been weak, while corporate profits have surged. "We're going to enter a world in which there's more wealth and less need to work," says Erik Brynjolfsson. "That should be good news. But if we just put it on autopilot, there's no guarantee this will work out."

Spacecraft Spots Probable Waves On Titan's Seas 81

Posted by Soulskill
from the surf's-up dept.
sciencehabit writes: It's springtime on Titan, Saturn's giant and frigid moon, and the action on its hydrocarbon seas seems to be heating up. Near the moon's north pole, there is growing evidence for waves on three different seas, scientists reported at a meeting of the American Geophysical Union. Researchers are also coming up with the first estimates for the volume and composition of the seas. The bodies of water appear to be made mostly of methane, and not mostly ethane as previously thought. And they are deep: Ligeia Mare, the second biggest sea with an area larger than Lake Superior, could contain 55 times Earth's oil reserves.

Researchers Accidentally Discover How To Turn Off Skin Aging Gene 165

Posted by Soulskill
from the vain-mice-everywhere-rejoice dept.
BarbaraHudson sends this excerpt from The Province: While exploring the effects of the protein-degrading enzyme Granzyme B on blood vessels during heart attacks, professor David Granville and other researchers at the University of British Columbia couldn't help noticing that mice engineered to lack the enzyme had beautiful skin at the end of the experiment, while normal mice showed signs of age. The discovery pushed Granville's research in an unexpected new direction.

The researchers built a mechanized rodent tanning salon and exposed mice engineered to lack the enzyme and normal mice to UV light three times a week for 20 weeks, enough to cause redness, but not to burn. At the end of the experiment, the engineered mice still had smooth, unblemished skin, while the normal mice were deeply wrinkled.

Granzyme B breaks down proteins and interferes with the organization and the integrity of collagen, dismantling the scaffolding — or extra-cellular matrix — that cells bind to. This causes structural weakness, leading to wrinkles. Sunlight appears to increase levels of the enzyme and accelerate its damaging effects.

An anonymous reader writes: Google's Chris DiBona told a London conference last week that ODF support was coming next year, but today the Google Drive team unexpectedly launched support for all three of the main variants — including long-absent Presentation files. You can now simply open ODT, ODS and ODP files in Drive with no fuss. It lacks support for comments and changes but at least it shows progress towards full support of the international document standard, something conspicuously missing for many years.

Jason Koebler writes: Tucows Inc., an internet company that's been around since the early 90s — it's generally known for being in the shareware business and for registering and selling premium domain names — announced that it's becoming an internet service provider. Tucows will offer fiber internet to customers in Charlottesville, Virginia — which is served by Comcast and CenturyLink — in early 2015 and eventually wants to expand to other markets all over the country. "Everyone who has built a well-run gigabit network has had demand exceeding their expectations," Elliot Noss, Tucows' CEO said. "We think there's space in the market for businesses like us and smaller."

11 Trillion Gallons of Water Needed To End California Drought 311

Posted by Soulskill
from the everybody-send-2,000-gallons-of-water-to-california dept.
mrflash818 points out a new study which found that California can recover from its lengthy drought with a mere 11 trillion gallons of water. The volume this water would occupy (roughly 42 cubic kilometers) is half again as large as the biggest water reservoir in the U.S. A team of JPL scientists worked this out through the use of NASA's Gravity Recovery and Climate Experiment (GRACE) satellites. From the article: GRACE data reveal that, since 2011, the Sacramento and San Joaquin river basins decreased in volume by four trillion gallons of water each year (15 cubic kilometers). That's more water than California's 38 million residents use each year for domestic and municipal purposes. About two-thirds of the loss is due to depletion of groundwater beneath California's Central Valley. ... New drought maps show groundwater levels across the U.S. Southwest are in the lowest two to 10 percent since 1949.
