I love my Prius, it’s true. But sometimes, I look at the Dodge Charger (I’m watching Burn Notice this summer) and think, “What a cool car.” And when we think of cool cars, it’s hard to keep the image of a muscle car or a sports car from popping up. But when you think of environmentally friendly, those types of cars don’t even come to mind. Perhaps the latest creation from a software engineer will changes the stereotypes.

Gas 2.0 reports on the effort put into creating the Electric Raptor:”The project took 2 years and an estimated 2000 hours to complete, but the results are pretty impressive. Using a 3-phase AC induction motor and 290 nickel-hydride batteries, Atkinson’s “Raptor” reaches 0-60 mph in 8 seconds, with a top speed of 100 mph. Maximum range is about 80 miles, with a full recharge taking just 3 hours. That is much less time spent recharging than most other production electric cars can boast.”Of course, this is a kit car, and it doesn’t have the same rigorous crash test standards and other cars have. But, even at $85,000, the Electric Raptor still costs less than current incarnations of similar cars that are all-electric. But what if it were mass-produced? If car companies could figure out how to build the kinds of all-electric cars that people would want to drive, for a price that they could afford, we’d be much further down the road to independence from fossil fuels.Assuming we could switch our grid to rely more on renewables, of course. No matter how cool the car is, if you have to charge it using coal or oil generated electricity, it’s still not as earth-friendly as it could be.© 2009 PhysOrg.com
(PhysOrg.com) — A 20-day expedition aiming to create a virtual 3-D map of the R.M.S. Titanic wreck site is about to leave St. Johns in Newfoundland carrying the latest technologies and dozens of scientists from the Woods Hole Oceanographic Institution in Massachusetts, the National Oceanic and Atmospheric Administration, Waitt Institute, and other scientific institutions. The expected result of the project, named “Expedition Titanic” will be the most precise 3-D images ever recorded of the Titanic site, and a virtual model that everyone will be able to explore. The group will use advanced sonar, robotics, 3-D high resolution/high definition cameras and acoustic imaging technologies to build a three-dimensional map that will eventually be made available online on the already amazing Expedition Titanic website, allowing anyone to explore the wreck from the comfort of home. Woods Hole scientist and director of special operations, David Gallo, said it would be the first archaeological site map of the wreck, and will be the first time a 3-D model has ever been attempted of such a large, irregularly shaped object in such deep water. Previous trips to the wreck site have been mainly for adventure, exploration, or attempts to find and remove artefacts.The Titanic sank on its maiden voyage in April 1912, but the wreck site was only located in 1985 by scientists from the Woods Hole Oceanographic Institution (WHOI), and so far only around half the site (or less) has been fully surveyed. The three by five kilometer (2 x 3 mile) debris field lies in the North Atlantic ocean at a depth of 3.82 km (about 2.4 miles). Salvage rights are owned by Atlanta-based company RMS Titanic Inc., which is funding the 3-D mapping expedition. Physically raising the Titanic would probably be cost-prohibitive, and given the fragile nature of the deteriorating ship remnants, would almost certainly be impossible. Expedition Titanic is an effort to “raise” the Titanic in the virtual world instead.Gallo said the expedition would record images of the wreck site using 3-D cameras on remotely operated and autonomous underwater vehicles. Among these will be WHOI’s own Remote Environmental Measuring Units (REMUS), which are unmanned vehicles that travel in a set pattern collecting data. Sonar points will be set up at around 30 locations around the bow to take an “acoustic snapshot” at each point. Other goals of the project are to establish a model for the management of shipwrecks in deep water to help in their preservation and to study the deterioration of the Titanic continuing as microbes gradually transform the steel into “rusticles”.

© 2013 Phys.org According to the ad, the Senior Director of Industrial Design will define and execute design strategies for wearable devices. The organization is asking for at least seven years or more in a senior position of industrial design and a show of fifteen years’ experience “in design of tech, consumer product and/or apparel.” A Bachelors in design is required, and the ad also lists “postgraduate in related field.” The company said its ambition is to make Motorola a recognized leader in the design of all things mobile. “We will do this by creating product experiences that are lead [sic] by consumer insight and intuition, keen design sensibility and cutting edge technologies. We want our products and brand to be experienced and loved by millions of people worldwide. We want to create the new Motorola.”The “new Motorola” was the mantra last month, too, at the startup conference Techweek. The Motorola Mobility tech lead, Rachid Alameh, talked about wearables at the center of innovation and Jim Wicks, senior vice president of consumer experience design, spoke about Motorola Mobility reshaping itself to make mobile products with a difference. Wicks predicted that users will no longer be “hunched” over mobile devices, a clear indication that they will explore products that users can wear. Whoever gets the job will no doubt be encouraged to go forth and champion innovation, encouragement not only by Wicks but by ex-DARPA director Regina Dugan, who is now Motorola Mobility head of the Advanced Technology and Research Group.Dugan spoke about wearables and bolder directions in wearables when she was on stage at the All Things Digital Conference in May. She revealed an electronic “tattoo” on her arm that she said was being explored as a patch which people could use as wearable body authentication. She said it was high time for a new path to authentication. “After 40 years of advances in computation, we’re still authenticating basically the same way we did years ago.”She also displayed a concept of a daily vitamin pill used as wearable body authentication. In this instance, the person, she said, would ingest a pill with a small chip inside it with a switch. Motorola Mobility, which Google acquired in 2012 for $12.5 billion, is doing a serious talent search for a newly minted “Senior Director Industrial Design-Wearables,” according to a recent job posting that lists Chicago as the job locale. It is not only job news but tech news, as a sideshow peek at what Motorola Mobility has in mind as it faces its highly competitive future. In short, Motorola Mobility is attempting to beef up a we-are-number-one, world class design group for computer wearables. The job posting said Motorola Mobility is looking for the right candidate who can “provide strategic leadership, champion innovation and institute best practices to create a new world-class wearable’s design group within Motorola.” The new hire will have someone to watch over him or her, as the new hire will report to the Senior Vice President of CXD, which is Motorola lingo for Consumer Experience Design.

(Phys.org) —Neil Hall, a genomics professor with the University of Liverpool, has kicked up a bit of an Internet storm. He’s written a paper and has had it published in the journal Genome Biology, suggesting (with tongue firmly in cheek) that some scientists are getting more attention than they deserve, due to their heightened social standing. He’s even come up with a way to measure it, his so-called “Kardashian-index” or more simply, K-index—it’s derived by noting how many people are following the scientist on Twitter and then dividing that number by followers the scientist probably should have due to papers written and associated citations for it, i.e. proof of actual work done. The index is named after Kim Kardashian (and her family) of course, who have become famous for being famous—they don’t actually do anything. And that’s the point of Hall’s paper—is the scientific community in danger of being overrun by scientists who make a lot of noise in the social media world, but do very little actual scientific work? Hall notes that there seems to be times when scientists are asked to give talks at conferences based more on their social standing than on work they have actually done. This begs the question, are scientists (regardless of field) just as susceptible to the cult of celebrity as everyone else and if so, is it harming science?Hall’s K-index isn’t going to help answer such questions, after all, a high index could mean that a scientist simply has an engaging social presence that has nothing to do with his or her professional life or accomplishments. But even that fact gives cause for wonder—if a scientist becomes famous among non-scientists (despite having done very little actual science) and is trotted out on talk shows and is proclaimed a prominent expert in their field, what impact does that have on non-scientists watching? Is it possible we could see scientists who become the academic world’s version of pop singers who succeed due to their media presence rather than their (auto tuned) talent? It’s hard to say of course, though not impossible to imagine.Hall also notes something very serious he came across in his research, the lack of female scientists with a strong social presence—it’s all related to a long history of women scientists being ignored by the scientific community, he bemoans, listing multiple examples of women that have been ignored by not only those in their field, but the general populace. Let’s hope a high K-index isn’t the fix.

While social media is a valuable tool for outreach and the sharing of ideas, there is a danger that this form of communication is gaining too high a value and that we are losing sight of key metrics of scientific value, such as citation indices. To help quantify this, I propose the ‘Kardashian Index’, a measure of discrepancy between a scientist’s social media profile and publication record based on the direct comparison of numbers of citations and Twitter followers.

Spider walks like an ant and raises front legs to mimic ant antenna Explore further A trio of researchers from Switzerland and the U.S. has found documented evidence of tiny regal jumping spiders killing and eating much larger frogs and lizards. In their paper published in Journal of Arachnology, Martin Nyffeler, with the University of Basel, G. B. Edwards with Florida State Collection of Arthropods and Kenneth Krysko with the University of Florida, describe their findings. Scientists and everyday people have seen multiple examples of frogs, lizards and other creatures dining on small spiders, but more rare is when the reverse happens. In this new effort, the researchers report on evidence they have uncovered of the tiny, one-inch-long regal jumping spider killing and eating frogs and lizards that are much larger than they are. Notably, despite its tiny size, the regal is actually one of the largest of the jumping spiders.The study began as the researchers exchanged anecdotal evidence of tiny spiders feasting on various vertebrate. Intrigued, they began conducting queries using several Google tools: Search, Books, Scholar and Pictures. They also did searches on the Scopus database and Thomson Reuters. These searches resulted in the discovery of six reports (and pictures) of tiny regal jumping spiders killing and consuming frogs and lizards. The pictures showed the one-inch spiders dining on Cuban frogs that were one to 1.5 times their own size, and lizards such as the Carolina anole that were 1.5 to 2.5 times their own size. The tiny spiders do not have to engage in battles with their prey; instead, they simply inject them with venom and then wait for them to die. The paper offers the first documented case of jumping spiders killing and eating vertebrates.The researchers note that regal jumping spiders, which live in Florida, belong to a group known as generalist predators. They do not have a primary food source. Instead, they are opportunists, killing whatever happens to cross their path. Prior research has already shown that the spiders have excellent eyesight, allowing them to spot prey and assess the chances of being able to kill and eat it before they take action.

When I was in 6th standard, I had flunked in class. I am appearing for my boards next year and my parents are extremely worried. They are constantly poking me and making me more nervous each day. What can I do?Vickey, South DelhiProbably the past is the reason why they are getting extra hyper. They are concerned too. But, you need to focus on your studies and forget everything about the surrounding. Do you have earplugs/ earphones? Just use them. Don’t let any external pressure pull your spirit down. We all have our lows and highs and it is just a matter of a few more months for situations to fall into place. Be patient, confident and concentrate on your exams.

How can we improve our sex life?Name unknownCouples end up in sexually unfulfilling marriages for a variety of reasons. Men may become more sexually assertive if they feel more in control, and women may feel more desire for a mate with newfound machismo. I suggest, start a date where the man chooses everything – your clothes, the restaurant, the food – as a starting point. Talk about it: Couples also benefit from simply communicating with their partners about what they want in bed. Sometimes sexy lingerie and dinners out are no substitute for an honest conversation about sex. Get raw. Get real. Of late we are fighting too much.

How can we fight less, is there any remedy?Trishna, AgraSome couples like to handle problems directly, and if each of the two people are this way, then they may resolve their problems more quickly and with less bitterness if they approach them head on. So it is always better to have a fight and sort out rather than bottling things up! Love more and I’m sure, you will fight less. Good Luck! Have a love or life query you cannot find an answer to?

Notwithstanding a raging row over remarks crediting Pakistan for peaceful elections in the state, Chief Minister Mufti Mohammed Sayeed on Monday remained unfazed saying he stood by what he had said yesterday.”What I said, I stand by it,” he said after assuming office today in civil Secretariat. However, he appeared to have tempered his yesterday’s remark when he said “this voter slip has been given to us by Constitution of India. The people of state have more faith in this (right).” Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJIAs Sayeed’s daughter and PDP Chief, Mehbooba Mufti stood by her father’s statement, remarking he had not said anything wrong, a group of PDP MLAs came out with a signed statement demanding that the Centre hand over the mortal remains of Guru, who was hanged and buried inside Tihar Jail in Delhi on February nine, 2013.She, however, admitted that there would be teething problems as both parties had diametrically opposite views on various issues. “We will have teething problems and everything can’t be hunky dory overnight”, she said.

Not satisfied with Singh’s reply, the Congress walked out of the Lok Sabha saying only the Prime Minister’s clarification would matter.Leader of Congress Mallikarjun Kharge said since the Prime Minister was told by Sayeed that he feels that the credit should go to Hurriyat, militants and Pakistan for smooth conduct of J and K assembly polls, Modi should make a statement. “Only PM can explain,” he said.To add to PDP’s discomfort, party MP and senior leader Muzaffar Hussain Baig felt the coalition government has not made a promising beginning with controversy erupting due to statements on both sides.He said that he would have preferred a clear cut statement on part of the two parties in their Common Minimum Programme (CMP) about talks with Pakistan and Hurriyat and revocation of Armed Forces Special Powers Act.””Let people decide whether the clauses in CMP on these issues are clear cut or whether they are capable of two different meanings, one that suits BJP and another that suits PDP. I would have preferred a clearcut statement and more clarity on these issues,” he told PTI here.Baig said that coalition government should be based on a “good faith agreement and not on compromise”.Ram Madhav, who was BJP’s key negotiator for the alliance with PDP, also disagreed with Sayeed’s comments “we attribute it (smooth polls) to three factors, the people of state, security agencies and the election commission.”Former Chief Minister and Working President of National Conference Omar Abdullah wondered whether Sayeed and his daughter were trying to break the alliance with their remarks on credit to Pakistan.”Has Mufti decided the Modi-Mufti accord was a mistake? Are the Father-Daughter duo trying to force BJP to break off the alliance? #wondering,” Omar wrote on micro-blogging site Twitter.
Tamil Nadu on Sunday reiterated its demand to authorise the use of Tamil language in the Madras High Court and urged the Centre to reconsider its stand on the issue.Speaking at the joint conference of chief ministers and chief justices of high courts, Tamil Nadu Chief Minister O Panneerselvam said the independence and the image of the judiciary should always be upheld by providing necessary infrastructure and ensuring a conducive environment.“If we are to take the administration of justice genuinely closer to the people, it is absolutely imperative that the local language is used in the High Court, as is already being done in the state government and in the state Legislature. Our government urges the Government of India and the Supreme Court to reconsider their stand in this matter and fulfil the long-standing aspiration and demand of the state to authorise the use of Tamil in the High Court of Madras,” he said.
