Submission + - Tesla's about to announce a battery-swap pilot program, how it works leaked

Submitted by cartechboy
cartechboy writes: Remember 18 months ago when Tesla promised it was going to launch battery-swap stations? Well, it's finally happening, sort of. It seems Tesla's about to announce a battery-swap pilot program that will launch next week. The swap site will be located across the street from a Tesla Supercharger site in Harris Ranch, California--184 miles south of San Francisco and about 200 miles north of Los Angeles. The pilot program will involve an unspecified number of Model S electric-car owners, who will be invited to take part in the test. For now, the battery-swap service will be offered by appointment only, at a cost of roughly a tank of gas in a premium sedan. Tesla's using words to describe this pilot program like "exploratory work" and "intended to test technology and assess demand" for a swapping service. While originally pitched that the battery swap would take less time than it would to take to refill the gas tank of a comparable luxury sedan, the company says now that "for this specific iteration" the swap process will take "approximately 3 minutes"--though it adds Tesla has "the ability to improve that time with future iterations." Is this test going to show that battery swapping is or isn't a realistic initiative?

Submission + - How a 3D Printer Let a Dog Run for the First Time (dice.com)

Submitted by Nerval's Lobster
Nerval's Lobster writes: Ever since 3-D printing began to enter the mainstream, people have discussed the technology’s potential for building prosthetic arms and legs for human beings. But what about doing the same for dogs? In one of those videos that ends up circulated endlessly on the Internet, a dog named Derby, born with a congenital deformity that deprived him of front paws, is outfitted with a pair of 3-D-printed prosthetics. With those "legs" in place, the dog can run for the first time, at a pretty good clip. Both the prosthetics and the video were produced by 3D Systems, which builds 3-D printers, and it seems likely that other 3-D-printing companies will explore the possibility of printing off parts for pets. And while the idea of a cyborg pooch is heartwarming, it will be interesting to see how 3D printers will continue to advance the realm of human prosthetics, which have become increasingly sophisticated over the past decade.

Submission + - Geoengineering Climate Cooling With Microbubbles

Submitted by Rambo Tribble
Rambo Tribble writes: Scientists from the University of Leeds have proposed that brighter ships' wakes, created by reducing their component bubbles' sizes, could increase their reflectivity and produce a cooling effect on the climate. The technology is touted as being available and simple, but side-effects might include such things as wetter conditions in some regions. Still, compared to many speculative geoengineering projects, "The one advantage about this technology — of trying to generate these tiny 'micro-bubbles' — is that the technology does already exist," according to Leeds' Prof Piers Forster.

Submission + - All the evidence the government will present in the Silk Road trial is online (dailydot.com)

Submitted by apexcp
apexcp writes: In less than a month, one of the biggest trials of 2015 will begin in New York City. The full list of government evidence and defense objections found its way online recently, shedding light on both the prosecutor's courtroom strategy and the defense team's attempted rebuttals. Also important is what's not presented as evidence. There's not a single piece of forensic documentation about how the FBI originally found Silk Road servers, an act the defense as called "blatantly criminal."

Submission + - Anyone Can Now Launch Their Own Version Of The Pirate Bay

Submitted by Anonymous Coward
An anonymous reader writes: Not satisfied with merely launching The Old Pirate Bay, torrent site isoHunt today debuted The Open Bay, which lets anyone deploy their own version of The Pirate Bay online. This is achieved via a new six-step wizard, which the group says requires you to be somewhat tech-savvy and have “minimal knowledge of how the Internet and websites work.” The Pirate Bay, the most popular file sharing website on the planet, went down last week following police raids on its data center in Sweden. As we’ve noted before, The Old Pirate Bay appears to be the best alternative at the moment, but since The Pirate Bay team doesn’t know if it’s coming back yet, there is still a huge hole left to be filled.

Submission + - Machine Intelligence Cracks Genetic Controls (quantamagazine.org)

Submitted by Anonymous Coward
An anonymous reader writes: Most genetic research to date has focused on just 1 percent of the genome — the areas that code for proteins. But new research, published today in Science, provides an initial map for the sections of the genome that orchestrate this protein-building process. “It’s one thing to have the book — the big question is how you read the book,” said Brendan Frey, a computational biologist at the University of Toronto who led the new research.

Frey compares the genome to a recipe that a baker might use. All recipes include a list of ingredients — flour, eggs and butter, say — along with instructions for what to do with those ingredients. Inside a cell, the ingredients are the parts of the genome that code for proteins; surrounding them are the genome’s instructions for how to combine those ingredients.

Just as flour, eggs and butter can be transformed into hundreds of different baked goods, genetic components can be assembled into many different configurations. This process is called alternative splicing, and it’s how cells create such variety out of a single genetic code. Frey and his colleagues used a sophisticated form of machine learning to identify mutations in this instruction set and to predict what effects those mutations have.

Submission + - Schneier explains how to protect yourself from Sony-style attacks (you can't) (wsj.com)

Submitted by phantomfive
phantomfive writes: Bruce Schneier has an op-ed in the Wall Street Journal discussing the Sony attack. He says, "Your reaction to the massive hacking of such a prominent company will depend on whether you’re fluent in information-technology security. If you’re not, you’re probably wondering how in the world this could happen. If you are, you’re aware that this could happen to any company."

Submission + - The Dominant Life Form in the Cosmos is Probably Superintelligent Robots

Submitted by Jason Koebler
Jason Koebler writes: If and when we finally encounter aliens, they probably won’t look like little green men, or spiny insectoids. It’s likely they won’t be biological creatures at all, but rather, advanced robots that outstrip our intelligence in every conceivable way.
Susan Schneider, a professor of philosophy at the University of Connecticut, joins a handful of astronomers, including Seth Shostak, director of NASA’s Search for Extraterrestrial Intelligence, NASA Astrobiologist Paul Davies, and Library of Congress Chair in Astrobiology Stephen Dick in espousing the view that the dominant intelligence in the cosmos is probably artificial. In her paper “Alien Minds," written for a forthcoming NASA publication, Schneider describes why alien life forms are likely to be synthetic, and how such creatures might think.

An anonymous reader writes: I’ve spent the last few weeks with Elite: Dangerous (since Gamma 1.0 was released to us Kickstarters), and about four problem-free hours tonight, on launch day (and I’ll be coming back here periodically as time passes and the game grows). Probably about an hour of all of that time was spent just scrolling through the key bindings, and subsequently pressing keys on my keyboard that I rarely, if ever touch. Yes, after 30 years Elite is back, and it’s already eating my life.

Submission + - Quantum physics just got less complicated (phys.org)

Submitted by wabrandsma
wabrandsma writes: From phys.org:
Here's a nice surprise: quantum physics is less complicated than we thought. An international team of researchers has proved that two peculiar features of the quantum world previously considered distinct are different manifestations of the same thing. The result is published 19 December in Nature Communications.
Patrick Coles, Jedrzej Kaniewski, and Stephanie Wehner made the breakthrough while at the Centre for Quantum Technologies at the National University of Singapore. They found that 'wave-particle duality' is simply the quantum 'uncertainty principle' in disguise, reducing two mysteries to one.

Submission + - Skeptics would like media to stop calling science deniers "skeptics" (csicop.org)

Submitted by Layzej
Layzej writes: Prominent scientists, science communicators, and skeptic activists, are calling on the news media to stop using the word “skeptic” when referring to those who refuse to accept the reality of climate change, and instead refer to them by what they really are: science deniers. “Not all individuals who call themselves climate change skeptics are deniers. But virtually all deniers have falsely branded themselves as skeptics. By perpetrating this misnomer, journalists have granted undeserved credibility to those who reject science and scientific inquiry.”

Submission + - Hackers' Shutdown of 'The Interview' Confirms Coding is a Superpower

Submitted by theodp
theodp writes: The idea of programming as a superpower was touched upon by CS teacher Alfred Thompson back in 2010, but it became a rallying call of sorts for the Hour of Code after Dropbox CEO Drew Houston described coding as "the closest thing we have to a superpower" in a Code.org video that went viral. And if the kids who learned to code with the President last week were dubious about the power of coding, this week's decision by Sony to scrap the release of the satirical film 'The Interview' after a massive hack attack should put aside any doubts, especially after new revelations that Sony had reached out to the White House for help and screened the film for administration officials back in June. White House press secretary Josh Earnest said Thursday that the Obama Administration is viewing the Sony attack as a 'serious national security matter' and is considering a range of possible options as a response, which could turn things into a contest of U.S. Superpower vs. Coding Superpower. In case it wasn't mentioned last week, remember to always use your coding superpower for good, kids!

Submission + - New Cargo Ship Is 488 Meters Long (bbc.com)

Submitted by Anonymous Coward
An anonymous reader writes: The BBC reports on the construction of Prelude, a new cargo 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.

Submission + - Researchers accidentally discover how to turn off skin aging gene

Submitted by BarbaraHudson
BarbaraHudson writes: 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.

Granville is also continuing to examine the effects of Granzyme B on aneurysms, especially of the aorta, the largest blood vessel in the human body. "When we inhibit Granzyme B in that model we can affect the collagen organization and strength of collagen in the aorta and prevent rupturing".

Submission + - Is the Higgs Boson a Piece of the Matter-Antimatter Puzzle? (stanford.edu)

Submitted by TaleSlinger
TaleSlinger writes: Why there's more matter than antimatter is one of the biggest questions confounding particle physicists and cosmologists, and it cuts to the heart of our own existence. In the time following the Big Bang, when the budding universe cooled enough for matter to form, most matter-antimatter particle pairs that popped into existence annihilated each other. Yet something tipped the balance in favor of matter, or we – and stars, planets, galaxies, life – would not be here.

The paper is based on a phenomenon called CP – or charge-parity – violation, the same phenomenon investigated by BaBar. CP violation means that nature treats a particle and its oppositely charged mirror-image version differently.

"Searching for CP violation at the LHC is tricky," Dolan said. "We've just started to look into the properties of the Higgs, and the experiments must be very carefully designed if we are to improve our understanding of how the Higgs behaves under different conditions.”

The theorists proposed that experimenters look for a process in which a Higgs decays into two tau particles, which are like supersized cousins of electrons, while the remainder of the energy from the original proton-proton collision sprays outward in two jets. Any mix of CP-even and CP-odd in the Higgs is revealed by the angle between the two jets.

"I wanted to add a CP violation measurement to our analysis, and what Matt, Martin and Michael proposed is the most viable avenue,” Philip Harris, a staff physicist at CERN and co-author of the paper said, adding that he's looking forward to all the data the LHC will generate when it starts up again early next year at its full design strength.

"Even with just a few months of data we can start to make real statements about the Higgs and CP violation," he said.
