The Death Cap Mushroom Is Spreading Across the US 274

Hugh Pickens DOT Com writes "Discovery News reports that the death cap mushroom is now an invasive species on every continent except Antarctica. It is spreading along the East and West Coasts of the U.S. and appears to be moving south into Mexico. 'When someone eats Amanita phalloides, she typically won't experience symptoms for at least six and sometimes as many as 24 hours,' says Cat Adams. 'Eventually she'll suffer from abdominal cramps, vomiting, and severely dehydrating diarrhea. This delay means her symptoms might not be associated with mushrooms, and she may be diagnosed with a more benign illness like stomach flu. To make matters worse, if the patient is somewhat hydrated, her symptoms may lessen and she will enter the so-called honeymoon phase.' Without proper, prompt treatment, the victim can experience rapid organ failure, coma, and death. But good news is on the way. S. Todd Mitchell of Dominican Hospital in Santa Cruz, California has treated more than 60 patients with a drug derived from milk thistle. The patients who have started the drug on time (within 96 hours of ingesting the mushroom) and who have still had kidney function intact have all survived. 'When administered intravenously, the compound sits on and blocks the receptors that bring amatoxin into the liver, thus corralling the amatoxins into the blood stream so the kidneys can expel them faster,' says Adams. Still, Mitchell cautions against the 'regular look"'of deadly mushrooms. 'They smell very good and when they're cooked, many patients have described them as the most delicious mushrooms they've ever eaten.'"

The Scent Rhythm Watch Tells Time By Releasing Fragrances 79

Zothecula writes "Glancing at a clock face in one form or another has been the de facto way to measure the passage of time. Aisen Caro Chacin though, is exploring a different perspective. She wants to give everyone the ability to tell time using their noses. Her chemical-based watch called the Scent Rhythm emits specially-designed fragrances in minute doses, in tune with circadian cycle of the human body. You get a fragrance of coffee in the morning, the smell of money in the afternoon, a relaxing whiskey scent in the evening, and a soothing chamomile fragrance at night. More than being merely pleasant, each chemically-supplemented scent aims to induce action appropriate to the time of day; the caffeine in the coffee scent for example, aims to trigger the person into being more active."

Silicon Brains That Think As Fast As a Fly Can Smell 84

Nerval's Lobster writes "Researchers in Germany have discovered what they say is a way to get computers to do more than execute all the steps of a problem-solving calculation as fast as possible – by getting them to imitate the human brain's habit of finding shortcuts to the right answer. A team of scientists from Freie Universität Berlin, the Bernstein Center Berlin, and Heidelberg University have refined the idea of parallel computing into one they describe as neuromorphic computing. In their design, a whole series of processors designed as silicon neurons rather than ordinary CPUs are linked together in a network similar to the highly interconnected mesh that links nerve cells in the human brain. Problems fed into the neuro mesh are broken up and processed in parallel, but not always using the same process. The method by which neuromorphic processors handle problems varies with the way they're linked together, as is the case with neurons in the brain. The chips are designed to copy the layout and functions of brain cells, but the way they're interconnected is based on another highly efficient biological model. 'The design of the network architecture has been inspired by the odor-processing nervous system of insects,' said one of the researchers. 'This system is optimized by nature for a highly parallel processing of the complex chemical world.' In tests using real-world datasets, the prototype was able to match the performance of specialized Bayeseian pattern-matching systems. Even better, the stable decisions reached by 'output neuron populations' take approximately 100 milliseconds, which is the same speed required by the insect nervous systems on which the network design is based, according to the paper."

Wisconsin Begins Using Cheese To De-Ice Roads 139

Hugh Pickens DOT Com writes "The NYT reports that Milwaukee has begun a pilot program to use cheese brine to keep city roads from freezing, mixing the dairy waste with traditional rock salt as a way to trim costs and ease pollution. 'You want to use provolone or mozzarella,' says Jeffrey A. Tews, the fleet operations manager for the public works department, which has spread the cheesy substance in Bay View, a neighborhood on Milwaukee's south side. 'Those have the best salt content. You have to do practically nothing to it.' Local governments across the country have been experimenting with cheaper and environmentally friendly ways of thawing icy thoroughfares, trying everything from sugar beet juice to discarded brewery grain in an attempt to limit the use of road salt, which can spread too thin, wash away and pollute waterways. 'If you put dry salt on a roadway, you typically lose 30 percent to bounce and traffic,' says Emil Norby, who works for Polk County and was the first in Wisconsin to come up with the cheese brine idea to help the salt stick. In a state where lawmakers once honored the bacterium in Monterey Jack as the state's official microbe, residents of Bay View say they have noticed little difference, good or bad, in the smell of their streets, and city officials say they have received no complaints. The mayor of Bay View says it's an experiment, but one that makes sense. The brine will come from the Dresser Farm in Polk County, where it is already being used on the roads. The only cost will be for transportation and distribution. 'We thought, 'Well, let's give it a shot.' The investment in this project is $1,474.'"

Digital Taste Interface 47

Tutter writes with news that Smellovision is being joined in reality by Tasteovision. "Possible applications in healthcare and gaming — it works by using electrodes on your tongue to stimulate salty, sweet, bitter and sour. It can produce the taste of virtual foods or drinks, allowing you to enjoy the taste without the calories (or chewing...). They are also good reasons to do this, for example, a diabetic can now taste sweets without actually affecting their blood sugar levels. Quote: 'The team is also working on a spin-off called a digital lollipop that will give the effect of a continuous sugar hit – but without sugar. For taste messaging they have developed TOIP — Taste Over Internet Protocol. This is a data format that makes it easy to transmit information on how to recreate the different tastes via the electrode. ... It is early days. The four major taste components, plus the fifth, the savoury 'umami' tang, are only a part of what we call flavor. Smell and texture are important, too — and the team now wants to work on adding those effects.' A video on youtube shows what it can do."

Xbox One Controller Cost Over $100 Million To Develop 206

mrspoonsi writes "The Xbox One controller went through many radical designs, including a built-in pico projector and a cartridge designed to release smell. Apparently, 'the core base didn't appreciate them,' so these wacky features were dropped in favor of a standard controller. According to VentureBeat, over $100 million worth of research went into the design they ended up using. 'Microsoft’s first tweaks for a new controller focused on the overall size and how it’d fit into hands, golden or otherwise. Using the Xbox 360 controller as a starting point, the engineers would make plastic-molded or 3D-printed prototypes that were each 1 millimeter wider or narrower than the last, testing a full range of up to plus or minus 8 millimeters. “That gave us the ability to test, with actual users including women and children, which width feels best,” said Morris. “We tested with more than 500 people throughout the course of the project. All ages, all abilities.” ... Morris and his team then looked at different thicknesses and shapes of the grips (or “lobes,” as he calls them), plus the angle of the triggers, different styles of analog sticks, and more.'"

Last Operating ICT 1301 Mainframe Computer Set To Run Again 56

Zothecula writes "What weighs 5.5 tons and has less computing power than your watch? A pioneering piece of computing history call 'Flossie,' the last operating ICT 1301 mainframe. The National Museum of Computing recently took delivery of the dismantled computer, which needed three moving vans to bring it to the museum's storage facility in Milton Keynes, UK. Rod Brown, custodian of Flossie for the past decade, said: 'Flossie has had an extraordinary life -- or more precisely four lives. After it was decommissioned at the University of London in about 1972, it was purchased at scrap metal prices by a group of students who ran an accounting bureau for about five years. They then advertised it in Amateur Computer Club Magazine and it was bought — again at scrap metal value. After languishing for a period in a barn in Kent, it was restored with the help of the Computer Conservation Society. Visitors could then come and see, smell, and feel the vibrations of a remarkable 1960's computer. Last year, Flossie was again at risk of being scrapped, but thanks to The National Museum of Computing the machine is safe again. The team and I are delighted with this news — especially because TNMOC has such an outstanding track record of restoring computers and maintaining them in full working order. We look forward to the day that it can go back on display.'"

Dutch Police Recruit Rats To Sniff Out Crime 80

An anonymous reader writes "Ratting someone out' just became much more literal. Dutch police are using trained rats to help keep the streets clean. 'Detective Derrick and his rat partners cost just £8 each and are capable of being trained to identify an impressive range of odors—including drugs and explosives—within ten to 15 days. In contrast, a police dog costs thousands of pounds and requires a minimum training period of eight months. The training procedure is straightforward: the rats are kept in a cage with four metal tea strainers attached inside, one of which contains gunpowder. When the rat recognizes the smell, it is rewarded with a "click" and a small treat. Eventually the rat will learn to move towards the smell instantly. In a demonstration it takes Derrick just two seconds to locate the offending odor."

Molecule In Corked Wine Plugs Up Your Nose 134

sciencehabit writes "Ever send a bottle of wine back at a restaurant? If you weren't just being a pretentious snob, then it was probably because the wine seemed 'corked' — had a musty odor and didn't taste quite right. Most likely, the wine was contaminated with a molecule called 2,4,6-trichloroanisole (TCA), the main cause of cork taint. But a new study by Japanese researchers concludes that you do not smell TCA directly; rather, TCA blocks up your sense of smell and distorts your ability to detect odors. The findings could help the food and beverage industry improve its products and lead to less embarrassment for both you and your waiter."

Smell Camera Snapshots Scents For the Future 117

An anonymous reader writes "Designer Amy Radcliffe has created an 'analog odor camera' that can be used to recreate a smell. From the article: 'When a smell source is placed under the device's glass cone, a pump extracts the smell via a plastic tube. After being drawn to Madeleine's main unit, the smell goes through a resin trap which absorbs the particles so molecular information can be recorded. That data is expressed in a graph-like formula, which essentially contains a fingerprint of the smell. In a special lab, that formula can then be inscribed on a bronze disk to artificially reproduce the smell. The smell can also be recreated in small vials.'"

Living In a Virtual World Requires Less Brain Power 89

sciencehabit writes "If you were a rat living in a completely virtual world like in the movie The Matrix, could you tell? Maybe not, but scientists studying your brain might be able to. Today, researchers report that certain cells in rat brains work differently when the animals are in virtual reality than when they are in the real world. In the experiment, rats anchored to the top of a ball ran in place as movie-like images around them changed, creating the impression that they were running along a track. Their sense of place relied on visual cues from the projections and their self-motion cues, but they had to do without proximal cues like sound and smell. The rodents used half as many neurons to navigate the virtual world as they did the real one."

Possible Chemical Weapons Use In Syria 164

Hugh Pickens writes "Mike Hoffman reports that Syria's Assad regime has accused the rebels of launching a chemical weapons attack in Aleppo that killed 25 people — an accusation the rebel fighters have strongly rebuked. A Reuters photographer said victims he had visited in Aleppo hospitals were suffering breathing problems and that people had said they could smell chlorine after the attack. The Russian foreign ministry says it has enough information to confirm the rebels launched a chemical attack while U.S. government leaders say they have not found any evidence of a chemical attack. White House spokesman Jay Carney says the accusations made by Assad could be an attempt to cover up his own potential attacks. 'We've seen reports from the Assad regime alleging that the opposition has been responsible for use. Let me just say that we have no reason to believe these allegations represent anything more than the regime's continued attempts to discredit the legitimate opposition and distract from its own atrocities committed against the Syrian people,' said State Department spokeswoman Victoria Nuland. 'We don't have any evidence to substantiate the regime's charge that the opposition even has CW (chemical weapons) capability.' President Obama has said the 'red line' to which the U.S. would send forces to Syria would be the use of chemical weapons. However, it was assumed the Assad regime would be the ones using their chemical weapons stockpile, not the rebels."

Mosquitoes Beginning To Ignore DEET Repellent 232

Copper Nikus writes "An article at the BBC makes a shocking claim about mosquitoes. It appears some individual insects in the wild have developed the ability to ignore the very popular DEET repellent after a first exposure. From the article: 'To investigate why this might be happening, the researchers attached electrodes to the insects' antenna. Dr Logan explained: "We were able to record the response of the receptors on the antenna to Deet, and what we found was the mosquitoes were no longer as sensitive to the chemical, so they weren't picking it up as well. "There is something about being exposed to the chemical that first time that changes their olfactory system - changes their sense of smell - and their ability to smell Deet, which makes it less effective."'"

Video Brewing Saké in Texas for Fun and Profit (Video) Screenshot-sm 134

Let's say you are an IT stud named Yoed Anis, you spent a year in Japan and decided you really like Saké, and you're back home in Austin, Texas. Since Texas, like Japan, grows lots of rice, you obviously need to start the Texas Saké Company to produce Rising Star and Whooping Crane Sakés, which you sell online and through a number of Texas restaurants and retailers. But whatever we can say in print pales beside a two-part brewery tour conducted by Toji Yoed himself, accompanied by Timothy Lord and his trusty camcorder. Yes, there's a transcription. But the video tour itself is better, even though it regretfully does not include the delightful aroma of Saké being made. (Someday, perhaps, Slashdot Studios will be equipped for Smell-O-Vision, but that's at least a few years off.)

The White Noise of Smell 82

Frosty P. writes "Scientists have discovered a new smell, but you may have to go to a laboratory to experience it yourself. The smell is dubbed 'olfactory white,' because it is the nasal equivalent of white noise, researchers report in the journal Proceedings of the National Academy of Sciences. Just as white noise is a mixture of many different sound frequencies and white light is a mixture of many different wavelengths, olfactory white is a mixture of many different smells. In a series of experiments, they exposed participants to dozens of equally mixed smells, and what they discovered is that our brains treat smells as a single unit, not as a mixture of compounds to break down, analyze and put back together again."

Has the Mars Rover Sniffed Methane? 119

First time accepted submitter GrimAndBearIt writes "NASA's Curiosity rover is poised to settle years of debate on the question of atmospheric methane on Mars, which would be a sign of microbial life. With parts per trillion sensitivity, it's not so much a question of whether the rover will be able to smell trace amounts of methane, but rather a question of how much. NASA has announced that Grotzinger's team will discuss atmospheric measurements at a briefing on 2 November. If the rover has detected methane at sufficiently high concentration, or exhibiting temporal variations of the kind that suggests microbial activity, then it will surely motivate a desire to identify and map the sources."
