There Aren't a Trillion Different Smells After All 48

New submitter Neuronaut137 writes: Last year a paper in Science magazine reported that humans can distinguish a trillion different odors, a result that had already made its way into neuroscience and psychology textbooks. Two new papers just published in eLife overturn that result, pointing to fatal flaws in experimental design and data analysis. Oh, well; thinking I had a superpower was fun while it lasted.

D.C. Police Detonate Man's 'Suspicious' Pressure Cooker 461

An anonymous reader writes: Yesterday evening in Washington D.C., police officers on routine patrol spotted an unoccupied car parked near the National Mall. They deemed it "suspicious," and took a look inside, where they found a pressure cooker. They also claimed to smell gasoline. The officers called the bomb squad, and at 7:45pm they initiated a controlled detonation of the car's contents. Afterward, a search of the car found no evidence that it contained explosives or any other hazardous materials. The car's owner was located and arrested for driving on a revoked license.

Kludgey Electronic Health Records Are Becoming Fodder For Malpractice Suits 184

Lucas123 writes The inherent issues that come with highly complex and kludgey electronic medical records — and for the healthcare professionals required to use them — hasn't been lost on lawyers, who see the potential for millions of dollars in judgments for plaintiffs suing for medical negligence or malpractice. Work flows that require a dozen or more mouse clicks to input even basic patient information has prompted healthcare workers to seek short cuts, such as cutting and pasting from previous visits, a practice that can also include the duplication of old vital sign data, or other critical information, such as a patient's age. While the malpractice suits have to date focused on care providers, they'll soon target EMR vendors, according to Keith Klein, a medical doctor and professor of medicine at UCLA. Klein has been called as an expert witness for more than 350 state or federal medical malpractice cases and he's seen a marked rise in plaintiff attorney's using EMRs as evidence that healthcare workers fell short of their responsibility for proper care. In one such case, a judge awarded more than $7.5 million when a patient suffered permanent kidney damage, and even though physicians hadn't neglected the patient, the complexity of the EMR was responsible for them missing uric kidney stone. The EMR was ore than 3,000 pages in length and included massive amounts of duplicated information, something that's not uncommon.

Planes Without Pilots 460

HughPickens.com writes: John Markoff writes in the NY Times that in the aftermath of the co-pilot crashing a Germanwings plane into a mountain, aviation experts are beginning to wonder if human pilots are really necessary aboard commercial planes. Advances in sensor technology, computing and artificial intelligence are making human pilots less necessary than ever in the cockpit and government agencies are already experimenting with replacing the co-pilot, perhaps even both pilots on cargo planes, with robots or remote operators. NASA is exploring a related possibility: moving the co-pilot out of the cockpit on commercial flights, and instead using a single remote operator to serve as co-pilot for multiple aircraft. In this scenario, a ground controller might operate as a dispatcher, managing a dozen or more flights simultaneously. It would be possible for the ground controller to "beam" into individual planes when needed and to land a plane remotely in the event that the pilot became incapacitated — or worse. "Could we have a single-pilot aircraft with the ability to remotely control the aircraft from the ground that is safer than today's systems?" asks Cummings. "The answer is yes."

Automating that job may save money. But will passengers ever set foot on plane piloted by robots, or humans thousands of miles from the cockpit? In written testimony submitted to the Senate last month, the Air Line Pilots Association warned, "It is vitally important that the pressure to capitalize on the technology not lead to an incomplete safety analysis of the aircraft and operations." The association defended the unique skills of a human pilot: "A pilot on board an aircraft can see, feel, smell or hear many indications of an impending problem (PDF) and begin to formulate a course of action before even sophisticated sensors and indicators provide positive indications of trouble." Not all of the scientists and engineers believe that increasingly sophisticated planes will always be safer planes. "Technology can have costs of its own," says Amy Pritchett. "If you put more technology in the cockpit, you have more technology that can fail.""

It's Time To Open Your Eyes 136

Morpheus writes: Good morning. I'm talking to you. Yes, you. The one with the squeaking chair and the monitor that needs cleaning. Right now you're wondering why your officemates haven't mentioned the weird story on Slashdot's front page. They haven't mentioned it because they can't see it. Not everyone can accept reality as it is. But you can.

You know. You've always known. The things you see, the things you hear, and smell — they aren't any more real than your dreams. You've drifted through life so far wondering when you're going to wake up. But you don't have to wonder anymore. This is your alarm clock. The only decision you have left to make — the only decision you've ever had to make — is whether you want to wake up, or turn it off and drift back to sleep. In exactly two minutes, your phone is going to ring. If you want to open your eyes, to be born into a world more real than you've ever imagined.. answer it.

At the Track With Formula E, the First e-Racing Series 167

An anonymous reader writes Ars is running a story about the new all-electric racing car series and its first visit to the U.S.. "The pit lane we're standing in is unusual, and not only because it's a temporary setup placed in the shadow of American Airlines Arena (home of the NBA's Miami Heat). Garages are set up on both sides rather than being limited to one. A few things also appear to be missing. To start, a familiar smell from the usual mix of burning hydrocarbons is absent. And it's remarkably quiet. The occasional impact wrench bursts out in a mechanical staccato, generators drone here and there, but there are no V8s burbling, no V6s screaming....Welcome to Formula E, the world's first fully electric racing series. Miami is playing host to the first of two US rounds—the next being held in Long Beach, CA, on April 4—and it's the fifth race in this ePrix's inaugural season. Given we've got a bit of a thing about racing at Cars Technica, as well as an obvious interest in electric vehicles, we had to be on the ground in Miami to experience this for ourselves."

The Case Against E-readers -- Why Digital Natives Prefer Reading On Paper 261

HughPickens.com writes: Michael Rosenwald writes in the WaPo that textbook makers, bookstore owners and college student surveys all say millennials still strongly prefer reading on paper for pleasure and learning. This bias surprises reading experts, given the same group's proclivity to consume most other content digitally. "These are people who aren't supposed to remember what it's like to even smell books," says Naomi S. Baron. "It's quite astounding." Earlier this month, Baron published Words Onscreen: The Fate of Reading in a Digital World, a book that examines university students' preferences for print and explains the science of why dead-tree versions are often superior to digital (PDF).

Her conclusion: readers tend to skim on screens, distraction is inevitable and comprehension suffers. Researchers say readers remember the location of information simply by page and text layout — that, say, the key piece of dialogue was on that page early in the book with that one long paragraph and a smudge on the corner. Researchers think this plays a key role in comprehension — something that is more difficult on screens, primarily because the time we devote to reading online is usually spent scanning and skimming, with few places (or little time) for mental markers.

Another significant problem, especially for college students, is distraction. The lives of millennials are increasingly lived on screens. In her surveys, Baron was surprised by the results to the question of whether students were more likely to multitask in hard copy (1 percent) vs. reading on-screen (90 percent). "When a digital device has an Internet connection, it's hard to resist the temptation to jump ship."

Why We Have To Kiss Off Big Carbon Now 441

mdsolar writes When the fossil-fuel divestment movement first stirred on college campuses three years ago, you could almost hear Big Oil and Wall Street laughing. Crude prices were flirting with $100 a barrel, and domestic oil production, from Texas to North Dakota, was in the midst of a historic boom. But the quixotic campus campaign suddenly has the smell of smart money.

One of the biggest names in the history of Big Oil – the Rockefellers – announced last September that they would be purging the portfolio of the Rockefeller Brothers Fund of 'risky' oil investments. And that risk has been underscored by the sudden collapse of the oil market. After cresting at more than $107 in mid-June, the price of a barrel of West Texas Intermediate dipped below $50 a barrel in early January. The crash carries big costs: Goldman Sachs warned that nearly $1 trillion in planned oil-field investments would be unprofitable – even if oil were to stabilize at $70 per barrel.

HTTP/2 - the IETF Is Phoning It In 161

An anonymous reader writes HTTP/2 is back in the spotlight again. After drawing significant ire over a proposal for officially sanctioned snooping, the IETF is drawing criticism for plowing ahead with its plans for HTTP/2 on an unrealistically short schedule and with an insufficiently clear charter. A few days ago the IETF announced Last Call for comments on the HTTP/2 protocol.

Poul-Henning Kamp writes, "Some will expect a major update to the world's most popular protocol to be a technical masterpiece and textbook example for future students of protocol design. Some will expect that a protocol designed during the Snowden revelations will improve their privacy. Others will more cynically suspect the opposite. There may be a general assumption of 'faster.' Many will probably also assume it is 'greener.' And some of us are jaded enough to see the "2.0" and mutter 'Uh-oh, Second Systems Syndrome.' The cheat sheet answers are: no, no, probably not, maybe, no and yes."

"Given this rather mediocre grade-sheet, you may be wondering why HTTP/2.0 is even being considered as a standard in the first place. The Answer is Politics. Google came up with the SPDY protocol, and since they have their own browser, they could play around as they choose to, optimizing the protocol for their particular needs. SPDY was a very good prototype which showed clearly that there was potential for improvement in a new version of the HTTP protocol. Kudos to Google for that. But SPDY also started to smell a lot like a 'walled garden'."

"The IETF, obviously fearing irrelevance, hastily 'discovered' that the HTTP/1.1 protocol needed an update, and tasked a working group with preparing it on an unrealistically short schedule. This ruled out any basis for the new HTTP/2.0 other than the SPDY protocol. With only the most hideous of SPDY's warts removed, and all other attempts at improvement rejected as 'not in scope,' 'too late,' or 'no consensus,' the IETF can now claim relevance and victory by conceding practically every principle ever held dear in return for the privilege of rubber-stamping Google's initiative."

Cell Transplant Allows Paralyzed Man To Walk 161

New submitter tiberus sends word of a breakthrough medical treatment that has restored the ability to walk to a man who was paralyzed from the chest down after his spinal cord was severed in a knife attack. A research team from the UK, led by Professor Geoff Raisman, transplanted cells from the patient's nose, along with strips of nerve tissue from his ankle, to the place where the spine was severed. This allowed the fibers in the spinal cord to gradually reconnect. The treatment used olfactory ensheathing cells (OECs) - specialist cells that form part of the sense of smell. ... In the first of two operations, surgeons removed one of the patient's olfactory bulbs and grew the cells in culture. Two weeks later they transplanted the OECs into the spinal cord, which had been cut through in the knife attack apart from a thin strip of scar tissue on the right. They had just a drop of material to work with - about 500,000 cells. About 100 micro-injections of OECs were made above and below the injury. Four thin strips of nerve tissue were taken from the patient's ankle and placed across an 8mm (0.3in) gap on the left side of the cord. ... Two years after the treatment, he can now walk outside the rehabilitation center using a frame.

Lost Sense of Smell Is a Strong Predictor of Death Within 5 Years 139

HughPickens.com writes: Mo Costandi reports at The Guardian that a new study shows losing one's sense of smell strongly predicts death within five years, suggesting that smell may serve as a bellwether for the overall state of the body, or as a marker for exposure to environmental toxins. "Olfactory dysfunction was an independent risk factor for death, stronger than several common causes of death, such as heart failure, lung disease and cancer," the researchers concluded, "indicating that this evolutionarily ancient special sense may signal a key mechanism that affects human longevity." In the study, researchers tested a group of volunteers for their ability to correctly identify various scents. Five years later, they retested as many of the volunteers as they could find.

During the five-year gap between the two tests, 430 of the original participants (or 12.5% of the total number) had died. Of these, 39% who had failed the first smell test died before the second test, compared to 19% of those who had moderate smell loss on the first test, and just 10% of those with a healthy sense of smell. Despite taking issues such as age, nutrition, smoking habits, poverty and overall health into account, researchers found those with the poorest sense of smell were still at greatest risk. The tip of the olfactory nerve, which contains the smell receptors, is the only part of the human nervous system that is continuously regenerated by stem cells. The production of new smell cells declines with age, and this is associated with a gradual reduction in our ability to detect and discriminate odors. Loss of smell may indicate that the body is entering a state of disrepair, and is no longer capable of repairing itself.

Robotic Taster Will Judge 'Real Thai Food' 103

HughPickens.com (3830033) writes The NYT reports that Thailand's former prime minister, Yingluck Shinawatra repeatedly encountered a distressing problem while traveling the world: bad Thai food. Too often, she found, the meals she sampled at Thai restaurants abroad were unworthy of the name, too bland to be called genuine Thai cooking. The problem bothered her enough to raise it at a cabinet meeting. Even though her political party has since been thrown out of office, in a May military coup, the Thai government is unveiling its project to standardize the art of Thai food using a robot. The government-financed Thai Delicious Committee, which oversaw the development of the machine, describes it as "an intelligent robot that measures smell and taste in food ingredients through sensor technology in order to measure taste like a food critic." Thailand's National Innovation Agency has spent about $100,000 to develop the e-delicious machine. The e-delicious machine has 10 sensors that measure smell and taste, generating a unique fingerprint (signature) for each sample of food that passes its digital maw. Generally with electronic tasting, there are electronic sensors that work just like the taste buds on your tongue, measuring the quantity of various taste-giving compounds, acidity, etc. While these electronic sensors can't actually tell you how something tastes — that's a very subjective, human thing — they are very good at comparing two foods scientifically. Meanwhile at a tiny food stall along one of Bangkok's traffic-clogged boulevards, Thaweekiat Nimmalairatana, questioned the necessity of a robatic taster. "I use my tongue to test if it's delicious or not," said Nimmalairatana. "I think the government should consider using a human to gauge authenticity."

CBC Warns Canadians of "US Law Enforcement Money Extortion Program" 462

jfbilodeau writes The CBC is warning Canadians about a U.S. program where America law enforcement officers — from federal agents to state troopers right down to sheriffs in one-street backwaters — are operating a vast, co-ordinated scheme to grab as much of the public's cash as they can through seizure laws. "So, for any law-abiding Canadian thinking about an American road trip, here’s some non-official advice: Avoid long chats if you’re pulled over. Answer questions politely and concisely, then persistently ask if you are free to go. Don’t leave litter on the vehicle floor, especially energy drink cans. Don’t use air or breath fresheners; they could be interpreted as an attempt to mask the smell of drugs. Don’t be too talkative. Don’t be too quiet. Try not to wear expensive designer clothes. Don’t have tinted windows. And for heaven’s sake, don’t consent to a search if you are carrying a big roll of legitimate cash.

Sniffing Out Billions In US Currency Smuggled Across the Border To Mexico 158

An anonymous reader writes "Criminals smuggle an estimated $30 billion in U.S. currency into Mexico each year from the United States, most of it laundered drug money. But researchers say help is on the way for border guards in the form of a portable device that identifies specific vapors given off by U.S. paper money. "We're developing a device that mimics the function of trained dogs 'sniffing' out concealed money, but without the drawbacks, such as expensive training, sophisticated operators, down time and communication limitations," says Suiqiong Li, Ph.D., a member of the research team behind the technology. When developing the device, the researchers first had to figure out which gases money emits and how fast that happens. It turned out that the gases are a set of trace chemicals, including aldehydes, furans and organic acids." What do bitcoins smell like?

It's Time To Plug the Loopholes In Pipeline Regulation 163

Hugh Pickens DOT Com (2995471) writes "Congresswoman Janice Hahn writes in the Daily Breeze that thousands of gallons of crude oil spilled onto a residential street in Wilmington, California when an idle pipeline burst in a residential neighborhood, wreaking havoc on the lives of families who live in the community. "With a noxious smell and the sounds of jackhammers engulfing the community, the residential neighborhood turned into a toxic waste site in less than an hour," says Hahn. "The smell was nauseating and unbearable. Extensive drilling on the street is causing damage to driveways and even cracking tile flooring inside homes. Residents have seen their lawns die within a two-week span and they worry that the soil may be toxic. Several residents have suffered from eye irritation, nausea, headaches and dizziness due to the foul oil odor, including an elderly woman who has lived in Wilmington for more than 20 years."
