To do so, they have voluntarily submitted them to the US Department of Agriculture (USDA) and the Canadian Food Safety Inspection Agency (CFSIA). The process for both is to first undergo a 60 day public comment period then secondly to have the product tested for health and safety. The CFSIA has already completed the comment period and will begin the safety inspection phase shortly. Meanwhile, opposition to the GM apples has grown. In a survey taken in Canada, sixty nine percent of 1,501 people polled said they would not support the approval of GM apples in their country. Across the border, the US Apple Association has announced its opposition to the sale of such apples, suggesting it would taint the image of apples grown in the United States.Okanagan Specialty Fruits maintains that the apples are not only safe, but would help improve sales of apples as they note that consumption of fresh apples in the US has fallen from an average of twenty pounds a year to just sixteen. They note that many people shy away from taking on a whole apple, but go for slices, but only those that haven’t turned brown. They say also that because grocery chains refuse apples that have browned due to bruising, non-browning apples would mean more money for growers.The process of modifying the apples, first developed in Australia by a team working with potatoes, involves placing an extra copy of a gene already in the apple that activates a self-defense mechanism that causes the gene responsible for the production of polyphenol oxidase, which is responsible for browning, to shut down. Okanagan Specialty Fruits has thus far developed just two varieties, Golden Delicious and Granny Smith which it plans to market under the name The Arctic Apple once they receive approval. Unfortunately for them, the Northwest Horticultural Council, which represents the fruit tree industry in Washington State, home to nearly sixty percent of the apples grown in the US, is also opposed to the idea. They say they don’t believe the apples are dangerous but believe it would be in the best interest of the apple industry to maintain the apple’s image as a natural healthy food.If approved the apples would represent the first genetically modified food sold directly to consumers in the United States. Other genetically modified food has been sold to the public for almost twenty years, but they have all appeared as processed ingredients.

Analyzing energy potential (Phys.org)—”Last winter, I fantasized about sitting at my computer while a camera-equipped drone followed him overhead.” That is the revelation of a father who provides a detailed account of building an Arduino-based gyrocopter that could follow his son, in grade school, who he normally walks 400 meters down a hill to the bus stop each morning. He chose a quadcopter design for its maneuverability and ability to hover. He did not buy a kit but instead got his parts separate. His project involved a central frame to hold the electronics, aluminum to support motors and propellers, and legs to cushion landings, a main control board and sensors, batteries, power distribution board, power controllers for the motors, radio receiver for standard remote-control flying, and an RF modem for computerized control. Explore further Credit: Paul Wallich, via IEEE Spectrum Paul Wallich, an IEEE Spectrum contributing editor shared many details behind his DIY device with the magazine. He chose an ArduPilot Mega for the main control board. ArduPilot Mega is a fully programmable autopilot that requires a GPS module and sensors to create a functioning Unmanned Aerial Vehicle. He said the whole board is powered by a 5-volt feed from one of the motor controllers. He installed Mission Planner on a Windows desktop to initialize the ArduPilot Mega’s firmware and calibrate all its sensors and controls. He decided against using RFID systems, opting instead for a GPS beacon. “Reading an RFID tag from meters rather than centimeters takes more amplification and a fancier antenna than I was willing to have my quadcopter carry.” How successful was he? Getting the thing up in the air was trivial. But he still had to rate his success based on how it worked. He said it “mostly” worked. Windy conditions were a problem, making the copter skittish. GPS guidance was good to ten meters at best. “Because my particular front yard is only about 15 meters across, with a long, tree-edged driveway leading to the street, I either have to follow automatically above the treetops—where I can’t really see what’s going on—or else supplement the autopilot with old-fashioned line-of-sight remote control.” Wallich said he plans more sonar units for “collision avoidance,” and maybe an optical flow sensor for better position control.He discovered another difficulty, rechargeable battery life. “Just hovering in the air requires two to three amperes; moving around or fighting a breeze expends twice that or more.” He said the typical 2200-milliampere-hour lithium-ion battery gave him just enough time to fly to the bus stop, wait a few minutes for the bus and fly back.

(Phys.org) —Adam Falkowski, a physicist working at CERN, on his Particle Physics Blog, is claiming that researchers on the BICEP2 team that uploaded a paper (First direct evidence of cosmic inflation) to the arXiv preprint server this past March have acknowledged to some in the science community that there may be a problem with their methodology. Members of the BICEP2 research team are denying Falkowski’s claim, but the assertion has led to rumors on the Internet that the team may not have found evidence of cosmic inflation after all. Explore further © 2014 Phys.org Cosmologists cast doubt on inflation evidence The Big Bang theory suggests the universe as we know it came to exist as the result of a giant explosion, approximately 14 billion years ago, followed by a rapid thrusting of material from the point of the explosion out into what we now observe as the universe around us. That thrusting has been dubbed the theory of cosmic inflation—it describes the rapid expansion of the universe. Adherents contend that during the initial phase of cosmic inflation, gravitational waves would have been generated, and should be still visible today. Last March, the BICEP2 team claimed in their paper that they had found evidence of such gravitational waves, giving cosmic inflation theory a huge boost.But now, some have suggested that there might have been a problem with the way the observations were made—a map the team used which was created by the ESA’s Planck team might have been interpreted incorrectly. To spot gravitational waves, the team had to rule out other signals it received based on data from a variety of sources. One of those sources, the map created by the Planck team included several possible sources of light, but the researchers at BICEP2 thought it only charted dust or ashes from exploding stars. This bit of news leads to a little bit of doubt about the results the team found, and now places them at the mercy of an update of the map by the Planck team.In the meantime, members of the BICEP2 team have been responding to the rumors and claim they are still confident in their results and that any gossip suggesting they have begun to doubt their work is wrong. Whether they believe their work is in jeopardy or not, is, of course, not really what’s important—finding out if what they reported is correct is what matters, and that is going to take some time.

After making a huge splash at India Art Fair earlier this year with his 3-D sculptural installations in metal, Israeli artiste David Gerstein is all set to exhibit a body of new works in his first solo show in India. Titled Poetic Mirror, the show is being brought to India by Bruno Art Group and is curated by Alka Pande. Born in Jerusalem in 1944, Gerstein studied in Jerusalem, Paris, New York and London and started exhibiting his work in 1971. He uses a large spectrum of media such as wall sculptures, paper cuts, prints and photographs and other small objects. He is most famous for his large, Fauve -like outdoor installations, which are very much part of the Israeli landscapes. Also Read – ‘Playing Jojo was emotionally exhausting’Though Gerstein has already tasted success in the Indian market with many of his works being sold to Indian collectors post India Art Fair, this is the first time he will be visiting the country. Says the artist who is considered the pioneer of 3-D metal art: ‘Unfortunately, I have never been to India before but for many years, I have been reading about it and hearing stories or seeing films that it seems I know what India is like. My passion for colours always makes people inquire whether India helped determine my love for strong fresh colours which is so typical to the Indian culture. After all, the Mediterranean culture and heritage which we share with India brings us to the same strong sun and shadows. I’m sure India will look familiar to me from the very beginning. Some of my works involve a lot of details and are rich in colours which in recent years have disappeared from the art world trends.’ Also Read – Leslie doing new comedy special with NetflixYet, Gerstein admits he looks forward to watching the way ‘life is being performed on Indian streets, to smell the food and to see the wonderful craft that is being done everywhere. India and Israel share the same landscape and vegetation since the weather is closed but I am more interested in urban scenes than just landscape views,’ he says.’My art has always traversed its own path apart from trendy movements and I have stayed away from the ‘isms’, though often it’s been called ‘pop art’. I was a narrative artist from the very beginning and wanted to get people’s attention by representing the values I share with the common art lover. I want to share beauty and happiness and make people aware that there are great values we have as people and not just violence and disasters. After many years of creating narrative and figurative images, I wanted to extend the borders of painting and to give a new sculptural dimension to the so far illusionist look of the flat paintings. By slicing the view to multi layers, I achieved certain volume that was lacking in all the paintings that were done before.’ Among the works that will be on display during the show is the swirling 5th Avenue, a busy street scene inspired by the artist’s stay in New York. Happy Hours depicts the sensation of freedom overwhelming two bikers surrounded by a cloud of butterflies. The powerful Endless walk represents a multicoloured crowd of people walking along lines that form the infinity symbol. Gerstein’s works convey a sense of wonder and amusement at this fervour-ridden reality that is ours, and can be interpreted as a metaphor of life as a mad race. The Burning Lips pass on the feeling of softness of the lips or the sensation of its great sensitivity. Elegance is a comment about femininity and Peloton Wave is all about movement and the way the human figure is integrated with the mechanism of the bicycle. ‘Each image has its own story and solution.’WHERE: Visual Arts Gallery, India Habitat CentreWHEN: 6 to 15 May, 10 am to 8 pm
