Can Iris-Scanning ID Systems Tell the Difference Between a Live and Dead Eye? (ieee.org) 50

the_newsbeagle writes: Iris scanning is increasingly being used for biometric identification because it's fast, accurate, and relies on a body part that's protected and doesn't change over time. You may have seen such systems at a border crossing recently or at a high-security facility, and the Indian government is currently collecting iris scans from all its 1.2 billion citizens to enroll them in a national ID system. But such scanners can sometimes be spoofed by a high-quality paper printout or an image stuck on a contact lens.

Now, new research has shown that post-mortem eyes can be used for biometric identification for hours or days after death, despite the decay that occurs. This means an eye could theoretically be plucked from someone's head and presented to an iris scanner. The same researcher who conducted that post-mortem study is also looking for solutions, and is working on iris scanners that can detect the "liveness" of an eye. His best method so far relies on the unique way each person's pupil responds to a flash of light, although he notes some problems with this approach.

CRISPR: Chinese Scientists To Pioneer Gene-Editing Trial On Humans (theguardian.com) 90

An anonymous reader quotes a report from The Guardian: A team of Chinese scientists will be the first in the world to apply the revolutionary gene-editing technique known as CRISPR on human subjects. Led by Lu You, an oncologist at Sichuan University's West China hospital in Chengdu, China, the team plan to start testing cells modified with CRISPR on patients with lung cancer in August, according to the journal Nature. CRISPR is a game-changer in bioscience; a groundbreaking technique which can find, cut out and replace specific parts of DNA using a specially programmed enzyme named Cas9. Its ramifications are next to endless, from changing the color of mouse fur to designing malaria-free mosquitoes and pest-resistant crops to correcting a wide swath of genetic diseases like sickle-cell anaemia in humans. The Sichuan University trial, it is important to note, does not edit the germ-line; its effects will not be hereditary. What the researchers plan to do is enroll patients with metastatic non-small cell lung cancer, Nature reported, and for whom other treatment options -- including chemotherapy and radiotherapy -- have failed. They will then extract immune cells from the patients' blood and use CRISPR to add a new genetic sequence which will help the patient's immune system target and destroy the cancer. The cells will then be re-introduced into the patients' bloodstream. The Guardian does note that CRISPR was approved for human trials in the U.S., but if it begins on schedule in August the Sichuan University study will beat them to the punch of being the first of its kind.

Issa Bill Would Kill A Big H-1B Loophole (computerworld.com) 233

ErichTheRed writes: This isn't perfect, but it is the first attempt I've seen at removing the "body shop" loophole in the H-1B visa system. A bill has been introduced in Congress that would raise the minimum wage for an H-1B holder from $60K to $100K, and place limits on the body shop companies that employ mostly H-1B holders in a pass-through arrangement. Whether it's enough to stop the direct replacement of workers, or whether it will just accelerate offshoring, remains to be seen. But, I think removing the most blatant and most abused loopholes in the rules is a good start. "The high-skilled visa program is critical to ensuring American companies can attract and retain the world's best talent," said Issa in a statement. "Unfortunately, in recent years, this important program has become abused and exploited as a loophole for companies to replace American workers with cheaper labor from overseas."

Scientists' Biggest Search For Dark Matter To Date Just Turned Up Nothing (sciencealert.com) 133

Peter Dockrill, reporting for ScienceAlert: For something that's hypothesised to make up more than 80 percent of the mass of the entire universe, it's no easy thing to detect the existence of dark matter. That's the conclusion the world is coming to today, after scientists announced that a massive $10 million experiment to find traces of elusive dark matter particles had failed after an exhaustive 20-month search. "We've probed previously unexplored regions of parameter space with the aim of making the first definitive discovery of dark matter," said physicist Cham Ghag from University College London in the UK, one of the scientists who took part in the Large Underground Xenon (LUX) project based in South Dakota. "Though a positive signal would have been welcome, nature was not so kind! Nonetheless, a null result is significant as it changes the landscape of the field by constraining models for what dark matter could be beyond anything that existed previously."Ars Technica has more details.

Scientists Find Chemical-Free Way To Extend Milk's Shelf Life For Up To 3 Weeks (digitaltrends.com) 249

An anonymous reader writes from a report via Digital Trends: Researchers at Purdue University and the University of Tennessee have found a non-chemical way to extend regular milk's shelf life to around 2-3 weeks, and without affecting the nutrients or flavor. The technology they've developed involves increasing the temperature of milk by just 10 degrees for less than a second, which is well below the 70-degree Celsius threshold needed for pasteurization. That quick heat blast is still able to eliminate more than 99 percent of the bacteria left from pasteurization. "The developed technology uses low temperature, short time (LTST) in a process that disperses milk in the form of droplets with low heat/pressure variation over a short treatment time in conjunction with pasteurization," Bruce Applegate, Purdue's associate professor in the Department of Food Science, explained to Digital Trends. "The resultant product was subjected to a taste panel and participants had equal or greater preference for the LTST pasteurized milk compared to normally pasteurized milk. The shelf was determined to be a minimum of two weeks longer than the standard shelf life from pasteurization alone." As for whether or not this method will make its way to store shelves, it won't in the near future. "Currently an Ohio-based milk processor is using this technology and distributing the milk," Applegate says. "The unit is approved for processing milk in Ohio and distribution nationwide. The product is currently being distributed, however it has not been labeled as extended shelf life milk. Once the commercial application is validated the milk will be labelled with the extended shelf life." Scientists from Duke University believe there may be a large source of hydrogen gas under the ocean, caused by rocks forming from fast-spreading tectonic plates.

Large Source Of Hydrogen Gas May Lie Near Slow-Spreading Tectonic Plates Under The Ocean (sciencedaily.com) 71

New submitter pyroclast writes: According to research from Duke University, rocks forming from fast-spreading tectonic plates create hydrogen gas in large quantities. The tectonic alternation of hydrolyzed ultramafic rock to serpentinized rock has the byproduct of hydrogen gas. Science Daily reports: "'A major benefit of this work is that it provides a testable, tectonic-based model for not only identifying where free hydrogen gas may be forming beneath the seafloor, but also at what rate, and what the total scale of this formation may be, which on a global basis is massive,' said [researcher] Lincoln F. Pratson[.] 'Most scientists previously thought all hydrogen production occurs only at slow-spreading lithosphere, because this is where most serpentinized rocks are found. Although faster-spreading lithosphere contains smaller quantities of this rock, our analysis suggests the amount of H2 produced there might still be large,' [researcher Stacy] Worman said. [S]cientists need to understand where the gas goes after it's produced. 'Maybe microbes are eating it, or maybe it's accumulating in reservoirs under the seafloor. We still don't know,' Worman said. 'Of course, such accumulations would have to be quite significant to make hydrogen gas produced by serpentinization a viable fuel source.'"

Man Builds $1.5 Million Star Trek-Themed Home Theater (cepro.com) 158

CIStud writes: This $1.5 million "Star Trek" home theater is the envy of every geek on the planet. The theater is a reconstruction of the bridge of the Starship Enterprise from "Star Trek: Next Generation" and also includes $1 million worth of memorabilia from the classic sci-fi TV show. The home theater was created by financier Marc Bell with the help from Jay Miller of Boca Raton-based Acoustic Innovations. The two started working on the home cinema in 2002 -- before construction of Bell's house even began -- and it took them four years to complete. CEPro reports: "A D-Box controller manipulates hydraulics installed beneath the floorboards, meaning the entire room shakes when anything loud happens on screen. The room also includes a JBL Synthesis sound system, which at the time of installation was only used in commercial theaters. The audio system is currently being upgraded to Dolby Atmos specifications and Bell plans to install a 4K projector. A big movie fan, Bell has had over 3,500 films digitized, which are stored and streamed through a Kaleidescape server. He also spent approximately $35,000 on a Prima Cinema system, allowing him and his family to watch films at home the day they are released in commercial cinemas. A wraparound control center surrounds the 11 custom leather chairs in the theater, eight of which recline into beds, while the doors that open into the theater are exact replicas of the Turbolift doors as seen on the TV show. When someone steps on the circular "transporter," the doors open with that familiar "whoosh" sound." Bell apparently likes to spend his money on others too. He has rented a local movie theater for every Star Trek film released in the past 25 years and has taken all of his employees, friends and their children along on opening night. The Wall Street Journal posted a video on YouTube of the home theater.

Tesla's 'Master Plan, Part Deux' Includes Trucks, Buses and Ride-Sharing (latimes.com) 171

An anonymous reader writes from a report via Los Angeles Times: After teasing Part 2 of his "master product plan" for over a week, Elon Musk finally delivered. Los Angeles Times reports: "In a blog post published on the automaker's website, Musk introduced a multiyear, four-pronged strategy that includes new kinds of Tesla vehicles, expanded solar initiatives, updates on Tesla's 'autopilot' technology and a ride-sharing program. Commercial trucks, buses, a 'future compact SUV' and a 'new kind of pickup truck' will be added to Tesla's fleet of electric cars. A heavy-duty truck called the Tesla Semi and a shrunken bus that Musk called a 'high passenger density urban transport' vehicle are in early development stages 'and should be ready for unveiling next year,' he said. The smaller bus would be designed without a center aisle, with seats close to the entrances, and would be able to automatically pace themselves with traffic, the post said. The bus driver would become a 'fleet manager.' Musk also used the master plan to defend his bid for rooftop solar power provider SolarCity and said he aims to make Tesla's Autopilot robotic driver-assist system 10 times safer than cars that humans drive manually. Musk also plans to move Tesla into the popular ride-sharing business, not only with an Uber-like fleet but also with an app that lets Tesla owners rent out their vehicles when they're not using them, perhaps defraying a portion of their auto loans. This will happen, he said, 'when true self-driving is approved by regulators,' a turn of events that's at least several years away."

Corning Unveils Gorilla Glass 5, Can Survive Drops 'Up To 80% Of The Time' (theverge.com) 110

An anonymous reader writes from a report via The Verge: Corning has unveiled their new Gorilla Glass 5, which should make its way to high-end smartphones and other electronic devices later this year and into 2017. Gorilla Glass 5 is designed to improve drop performance from devices that are dropped onto rough surfaces from waist heigh to shoulder height. Corning says it can survive up to 80 percent of the time when dropped from 1.6 meters. For comparison, Gorilla Glass 4, which was released in the fall of 2014, was marketed as being twice as tough as the previous version and twice as likely to survive drops onto uneven surfaces from about a meter high. Some things to note include the fact that in Corning's tests, the 80 percent survival rate was with pieces of glass that were 0.6mm thick -- Corning now makes glass as thin as 0.4mm. Depending on how thin manufacturers want the glass in their devices, the durability results may vary. Also, most of demos consisted of dropping the glass face down, rather than on its side or corner. Corning's vice president and general manger John Bayne said if the glass is dropped in such a way, it's going to depend on the overall design of the phone, not just the glass. Gorilla Glass 5 is currently in production, though the company says we'll hear more about it "in the next few months." There's no word as to whether or not the glass will be ready in time for the wave of devices expected this fall.

47 Years Ago Today, Apollo 11 Landed On the Moon (foxnews.com) 184

An anonymous reader writes: At this point 47 years ago we had begun our orbit around the Moon," writes Buzz Aldrin in a tweet. Today, Wednesday, July 20th, 2016, marks the 47th anniversary of when NASA astronauts landed on the moon for the very first time. Fox News reports: "Astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins blasted off from Earth on a massive Saturn V rocket on July 16, 1969. Four days later, the Eagle module landed on the surface with Aldrin and Armstrong inside; Collins stayed behind in the orbiting Columbia craft. Millions of people back on Earth watched, captivated, as Armstrong was the first down the ladder, then uttered his now-famous line: 'That's one small step for man, one giant leap for mankind.' The astronauts eventually returned to Earth, splashing down four days later in the Pacific. On the moon, an American flag and a plaque that read, in part, 'We came in peace for all mankind,' remained." To this day, only 12 people have ever walked on the moon. Hopefully, that number will increase within the next decade. NASA is also celebrating the 40th anniversary of the Viking 1 lander's arrival on Mars. Viking 1 was the first American craft to land on the red planet on July 20, 1976.

EPA's Gasoline Efficiency Tests Provide No Valid Information At All (hotair.com) 136

schwit1 writes from a report via Behind The Black: The tests the EPA uses to establish the fuel efficiency of cars are unreliable, and likely provide no valid information at all about the fuel efficiency of the cars tested. Robert Zimmerman reports from Behind The Black: "The law requiring cars to meet these fuel efficiency tests was written in the 1970s, and specifically sets standards based on the technology then. Worse, the EPA doesn't know exactly how its CAFE testing correlates with actual results, because it has never done a comprehensive study of real-world fuel economy. Nor does anyone else. The best available data comes from consumers who report it to the DOT (WARNING: Source may be paywalled) -- hardly a scientific sampling. Other than that, everything is fine. Companies are forced to spend billions on this regulation, the costs of which they immediately pass on to consumers, all based on fantasy and a badly-written law. Gee, I'm sure glad we never tried this with healthcare!"

There's A 50% Chance of Another Chernobyl Before 2050, Say Safety Specialists (technologyreview.com) 140

An anonymous reader writes from a report via MIT Technology Review: Spencer Wheatley and Didier Sornette at ETH Zurich in Switzerland and Benjamin Sovacool at Aarhus University in Denmark have compiled the most comprehensive list of nuclear accidents ever created and used it to calculate the chances of future accidents. They say there is a 50:50 chance that a major nuclear disaster will occur somewhere in the world before 2050. "There is a 50 percent chance that a Chernobyl event (or larger) occurs in the next 27 years," they conclude. Since the International Atomic Energy Agency doesn't publish a historical database of the nuclear accidents it rates using the International Nuclear Event Scale, others, like Wheatley and co, have to compile their own list of accidents. They define an accident as "an unintentional incident or event at a nuclear energy facility that led to either one death (or more) or at least $50,000 in property damage." Each accident must have occurred during the generation, transmission, or distribution of nuclear energy, which includes accidents at mines, during transportation, or at enrichment facility, and so on. Fukushima was by far the most expensive accident in history at a cost of $166 billion, which is 60 percent of the total cost of all other nuclear accidents added together. Wheatley and co say their data suggests that the nuclear industry remains vulnerable to dragon king events, which are large unexpected events that are difficult to analyze because they follow a different statistical distribution, have unforeseen causes, and are few in number. "There is a 50% chance that a Fukushima event (or larger) occurs in the next 50 years," they say.

Neuroscientists Have Isolated The Part Of The Brain That Controls Free Will (extremetech.com) 279

An anonymous reader quotes a report from ExtremeTech: Free will might have been the province of philosophers until now, but we've cracked the problem with an fMRI. Neuroscientists from Johns Hopkins report in the journal Attention, Perception, & Psychophysics that they were able to see both what happens in a human brain the moment a free choice is made, and what happens during the lead-up to that decision -- how activity in the brain changes during the deliberation over whether to act. The team devised a novel way to track a participant's focus without using cues or commands, avoiding a Schrodinger's-like dilemma of altering the process of choice by calling attention to it. Participants took positions in MRI scanners, and then were left alone to watch a split screen as rapid streams of colorful numbers and letters scrolled past on both sides. They were asked just to pay attention to one side for a while, then to the other side. When to switch sides, and for how long to look, was entirely up to them. Over the duration of the experiment, the participants glanced back and forth, switching sides dozens of times. In terms of connectivity in the brain, the actual process of switching attention from one side to the other was tightly linked with activity in the parietal lobe, which is sort of the top back quadrant of the brain. Activity during the period of deliberation before a choice took place in the frontal cortex, which engages in reasoning and plans movement. Deliberation also lit up the basal ganglia, important parts of the deep brain that handle motor control, including the initiation of motion. Participants' frontal-lobe activity began earlier than it would have if participants had been cued to shift attention, which demonstrates that the brain was planning a voluntary action rather than merely following an order. A report from Fast Company details how technology is making doctors feel like glorified data-entry clerks.

The Flux Capacitor Becomes World's Fastest Street-Legal Electric Car (arstechnica.com) 183

An anonymous reader writes from a report via Ars Technica: Jonny Smith now has the world's fastest street-legal electric car, called the Flux Capacitor. Previously, the Flux Capacitor was only Europe's fastest street-legal electric vehicle, with a less than 11 second, 1/4-mile time under it's belt. Now it can run the quarter-mile in 9.87 seconds, thanks to the extra 44 cells added to the existing 144-cell Hyperdrive Innovation lithium-ion battery pack. That has boosted the car from 370v to 400v and the range from about 30 miles (48km) to about 50 miles (80km). "The combination of big voltage, amps, and phenomenal grip gave us early ten-second quarter miles, and when we braved the RPM limit of the motors, we managed a nine [second run]," Smith told Ars Technica. "Despite all of this power and speed, the little Enfield still felt smooth, stable, and happy, which is unbelievable given that it was designed to do 40 miles an hour."

Facebook Pitches Laser Beams As The High-Speed Internet Of The Future (pcworld.com) 93

An anonymous reader quotes a report from PCWorld: Facebook says it has developed a laser detector that could open the airwaves to new high-speed data communications systems that don't require dedicated spectrum or licenses. The component, disclosed on Tuesday in a scientific journal, comes from the company's Connectivity Lab, which is involved in developing technology that can help spread high-speed internet to places it currently doesn't reach. At 126 square centimeters, Facebook's new laser detector is thousands of times larger. It consists of plastic optical fibers that have been "doped" so they absorb blue light. The fibers create a large flat area that serves as the detector. They luminesce, so the blue light is reemitted as green light as it travels down the fibers, which are then bundled together tightly before they meet with a photodiode. It's described in a paper published on Tuesday in the journal Optica. Facebook says there are applications for the technology both indoors and outdoors. Around the home, it could be used to transmit high-definition video to mobile devices. Outdoors, the same technology could be used to establish low-cost communications links of a kilometer or more in length. In tests, the company managed to achieve a speed of 2.1Gbps using the detector, and the company thinks it can go faster. By using materials that work closer to infrared, the speed could be increased. And using yet-to-be developed components that work at wavelengths invisible to the human eye, the speed could be increased even more. If invisible to humans, the power could also be increased without danger of harming someone, further increasing speed and distance.
