Adding to the fire is J.D. Powers, which came out with predictions of just 750,000 electric vehicles by 2015.Other critics have pointed out that the issue is rather moot though, since a million electric vehicles running by 2015, would still account for less than one half of one percent of all operating vehicles by that date. Others however, point out that by passing certain milestones, electric vehicles become ever more of a viable choice for American consumers, thus, paving the way for a boon in sales in later years.What’s not included in either report, unfortunately, due to the time frame in which they were created, is the current cost of gasoline and the possibility that it could reach $5 gallon in this country before the summer is out. While still not nearly as much as consumers are paying in Europe, it could provide a catalyst for change, and swifter acceptance of all-electric vehicles, as consumers find they have few other alternatives.After all is said and done, it appears that despite the massive amounts of money being spent to create their projections, by both government and those in the private sector, there are just too many variables involved to accurately predict where car sales are headed; so, in the end, we’ll all likely just have to wait and see how things develop.

(PhysOrg.com) — Fomalhaut b, thought to be the first exoplanet photographed directly, has come under increased scrutiny due to evidence of an unexpected divergence from its expected orbit. Paul Kalas, James Graham and their colleagues identified the planet in 2008 while studying photographs taken by the Hubble telescope in 2004 and 2006. At that time it appeared Fomalhaut b orbited just inside a dust cloud that circles around Fomalhaut, the star at the center of that solar system. Now however, new photographs of Fomalhaut b show that it actually crosses into the dust cloud, causing Toronto astronomer Ray Jayawardhana, at a recent exoplanet conference, to suggest that Fomalhaut b may not be an exoplanet after all. An exoplanet called Fomalhaut b has been photographed in an unexpected spot — so is it even an exoplanet at all? Image credit: NASA The whole story actually began back in 2005 when evidence arose from studies of the dust belt surrounding Fomalhaut, suggesting that at least one exoplanet (any planet not in our own solar system) existed in the system due to the behavior of the dust cloud. After years of studying photographs from Hubble, Kalas and his team came upon Fomalhaut b, an apparent exoplanet about the size of Jupiter (and three times its mass), orbiting some 1.72×1010 km from its sun. Unfortunately, more evidence regarding the exoplanet could not be had due to the malfunction of the camera onboard Hubble. It wasn’t until just last year that another picture of Fomalhaut b was finally made using a different camera on Hubble. The problem was, the exoplanet appeared in a different place than astronomers expected; a problem that has various astronomers offering various explanations. Some suggest that the projected orbit was wrong, while others say that maybe it’s not a planet at all, but a background star or something else altogether.Another problem is that there are other apparent anomalies as well. It’s too bright for its size example. Also, why aren’t other ground-based infrared telescopes able to detect its presence? Jayawardhana says that all of this combined information or lack thereof, should be enough to have Fomalhaut b removed from the exoplanet.eu database. Kalas, in response suggests that 1RXJ1609, an exoplanet that Jayawardhana and his team are studying, should be reviewed more closely as well.The whole argument, if that’s what it is, appears to suggest that perhaps more stringent means should be established for classifying exoplanets before they are announced as such. Also maybe, those astronomers in the field who seem to be just as interested in the limelight as in making new discoveries should perhaps take a closer look at how they are coming off to those reading about their spats in the press.

More information: Paper: Sensor-Embedded Teeth for Oral Activity Recognition, mll.csie.ntu.edu.tw/papers/TeethProbeISWC.pdf As scientists develop ways to make electronics smaller, researchers find new ways to use them. In this new effort, the team in Taiwan has developed a sensor that is small enough to fit inside of an artificial tooth, or to sit astride a natural one. The current sensor developed by the team uses very tiny wires to carry data from the sensor to a computer—future versions will use Bluetooth to allow for a wireless implementation.The sensor measures jaw movement, and because of that is able to identify different types of oral activities. Currently it is capable of recognizing (after calibration for each individual) the difference between chewing, smoking, coughing, eating and drinking. This, the researchers say, could be invaluable to dentists, doctors and other scientists. The device would allow a dentist, for example, to monitor teeth grinding, a doctor to verify how much a person is eating or smoking, and a behavioral scientist to measure stress levels.To verify the accuracy of the device, the research team enlisted the assistance of eight volunteers—each had a sensor affixed to a tooth and then was asked to perform several different activities (cough, chew gum, etc.) for approximately 30 seconds each while the computer analyzed the data and made a personal profile for them. Afterwards, each of the volunteers was then asked to engage in the various oral activities and the researchers report that the sensor and computer were 93.8 percent accurate in determining which activity was being performed.The research team is continuing to work on improving the sensor and expect to have a wireless product that is able to fit inside a normal crown very soon. Such a development would mean tooth sensors could become a standard procedure in dental offices if patients are willing to submit to their insertion for their personal purposes.

Journal information: Proceedings of the National Academy of Sciences A large team of researchers from across Europe and the U.K. has learned more about Neolithic history in Poland by studying the remains of people buried in a mass grave in a southern part of the country. In their paper published in Proceedings of the National Academy of Sciences, the group describes the results of DNA testing they conducted on the remains and what they found. Back in 2011, a mass grave was discovered near the southern Polish village of Koszyce. Prior research dated the remains to the Bronze Age. In this new effort, the researchers have conducted DNA testing on the remains of those found in the grave.The researchers report that they found the remains of 15 people—men, women and children—all from approximately 2880 to 2776 BCE. Items found in the gravesite alongside the human remains suggested that the remains were from the Globular Amphora culture. They also found that the people all belonged to four core families. They noted that the adult females were not related to one another, suggesting that they had once belonged to another group. Of the eight men found in the gravesite, four were half-brothers and the others shared second-degree relationship links.The researchers noted that a large proportion of older men seemed to be missing from the gravesite, suggesting they were away when a massacre occurred. The males in the grave were young, and only one of them had sired a child, which was also buried in the grave. In sharp contrast, the women were all mostly over 30 years of age, and four of them were mothers of children in the grave. The bodies were placed in the graves in significant ways, the researchers note, suggesting the men had returned, found their families dead and had buried them.DNA testing also confirmed that all 15 of the dead belonged to the Sphere Amphora culture. The researchers theorize that people from the Corded Ware culture likely encountered the Sphere Amphora people as they sought to expand their range. They further speculate that the two groups were likely unknown to one another because there was no shared DNA in the victims.

The Raqs Media Collective’s solo show at the National Gallery of Modern Art (NGMA) takes the form of an extended conversation around the concepts of time and the untimely which run through much of the collective’s past and present work, and acts as a working laboratory of the ideas that the practice of the Raqs collective is considering today, as it faces the future. With more than fifty works in a range of media – video, installations, mixed media assemblages, sound, photography, print and sculpture – Raqs turns Jaipur House, the original home of the NGMA, into a magical, labyrinthine container of stories, riddles, enigmas and possibilities. Also Read – ‘Playing Jojo was emotionally exhausting’This is kind of art making that is quirky, intensely intellectual, humorous, poetic as well as committed to the asking of tough questions in a turbulent world. The collective’s sustained history of more than twenty years of working and thinking together is reflected in this multi-layered exhibition which twists and turns the way we think about time, finds lost constellations in the sky, argues with the epics, asks questions about the meaning of value, strikes back at time, thinks about war, reflects on the urban condition, considers the laboring body and addresses the future of a four year old child. Also Read – Leslie doing new comedy special with Netflix The Raqs Media Collective (Jeebesh Bagchi, Monica Narula and Shuddhabrata Sengupta) has been highly visible on the International art scene for the last decade. They enjoy playing a plurality of roles, often appearing as artists, occasionally as curators, and sometimes as philosophical agent provocateurs. Raqs follows its self-declared imperative of ‘kinetic contemplation’ to produce a trajectory that is restless in terms of the forms and methods that it deploys even as it achieves a consistency of speculative procedures.

Stree presents a broad range of over 300 works from Swaraj Art Archive exploring the female form as perceived by both male and female artists spanning from the pre-independence to the post-independence era. The event begins from January 23 onwards and will be held at the Swaraj Archive, Sector 2, Noida. Divided into five categories, the exhibition is spread across mediums representing the woman as an emotion – harmony; love; pride; devotion; and acquiescence; throwing light on the stylistic differences in artists’ expression conveyed by the female form. Also Read – ‘Playing Jojo was emotionally exhausting’It includes works by about 100 artists, from Kalighat painters to Arpana Caur, whose names will not be disclosed on the walls, allowing the observer to walk through the show unaccompanied by the predisposition associated with the identity of an artist. The show provides a visual comparative of the iconography associated with each of the above emotions showcasing the depth of Indian art from the 1850’s to now.Every artist possesses an individual artistic sensibility which, when driven by raw emotion, truly manifests into his creation, affecting the form, composition and its dialogue with the observer. Also Read – Leslie doing new comedy special with NetflixDivided into five sub-concepts, the exhibition spreads across time, mediums, scales and histories representing the woman as an expression of an emotion.The exhibition comprises over 300 works representing the ‘woman’ as an expression of an emotion. Providing a visual comparative of the iconography associated with each of the emotions – Harmony, Love, Pride, Devotion and Acquiescence – the collection showcases the depth of Indian art from the 1850’s to the present. This Exhibition aims to show the depth of Indian Art in its entirety. The non-chronological display of the artworks, segregated via emotions, which translate themselves into certain physical decipherable forms, allows the viewer to read and dwell into the art itself, rather than assess it pragmatically based on market researches associated with specific artists. A small effort has been made with this exhibition for the art to speak for itself without being weighed down or enhanced by the artists’ biographies. The viewer will then experience art without judgment and/or in comparison to the plethora of stylistic languages through Indian Art.
Kolkata: Commemorating the occasion of World Environment Day on June 5, the Kolkata Municipal Corporation (KMC) has decided to take up a month-long awareness campaign on environment in all the schools across the city. The awareness campaign will not only cover KMC schools but also government and private schools in the city.”We have made elaborate plans for a month-long programme to mark the World Environment Day. We will take up awareness campaigns through documentary, magic shows and various posters to make it interesting for the students. The emphasis will be on curbing the use of plastic,” Member Mayor-in-Council (Environment ) Swapan Samaddar said.Sammadar feels that if students are made aware in a proper manner, they will inform their parents about the necessity of keeping the environment clean. The entire team of the Environment department of the civic body will be involved in the campaign and the MMiC himself will try to cover as many schools as possible. The Borough chairmans have been directed to take up awareness campaigns on environment at their respective boroughs. KMC has already prepared 3,000 banners and several hoardings for the campaign, which will focus on abstaining from the use of plastic, quitting of smoking, keeping the vicinity clean and planting of trees and saplings.”The use of plastic has turned into a menace in the city and awareness is the only way to prevent its excessive use,” a senior official of the Environment department of the civic body said. The campaign will kick off with a rally on June 5 from KMC office on SN Banerjee Road to College Square in presence of Mayor Sovan Chatterjee.The Environment department will hold a meeting with the Parks & Gardens department of the civic body in this regard on Saturday.
Kolkata: The Trinamool Congress (TMC) issued a whip today to its Lok Sabha members to be present in the House on July 20 when the opposition-sponsored no-confidence motion would be taken up for discussion. TMC chief national spokesperson Derek O’Brien told PTI that the whip was issued to all 34 party MPs in the Lok Sabha. “They (the MPs) will participate in the discussion and voting in the Lok Sabha and return to Kolkata,” he said. O’Brien added that the party would observe its annual “Martyr’s Day” rally in Kolkata on July 21. This year’s rally will be the 25th anniversary of the event. Lok Sabha speaker Sumitra Mahajan announced that the House will take up discussion and voting on the no-confidence motion on July 20. The motion was brought against the Narendra Modi government by the TDP and opposition parties.
Kolkata: The Trinamool Congress (TMC) will observe “black day” throughout West Bengal on August 4 and 5 to protest against the detention and “manhandling” of its leaders at the Silchar airport in Assam yesterday, a senior party leader said today. TMC secretary general and West Bengal Education Minister Partha Chatterjee said the party will observe “black day” in every block and district of the state on Saturday and Sunday. “We condemn the way the public representatives were manhandled and detained by the Assam police at the Silchar airport. They being MPs had every right to visit a place, but all rules were violated and our party delegation was stopped. This is shameful,” he told reporters here. An eight-member TMC delegation, which had six MPs, were stopped at the Silchar airport when they tried to enter Assam’s Cachar district to assess the ground realities after the final draft of the National Register of Citizens (NRC) was published in the north-eastern state on Monday.
