Explore further In its report, the DOE, (backed up by a statement from Assistant Energy Secretary David Sandalow) predicts that sales of plug-in electric (which excludes hybrids) vehicles will be sufficient between now and 2015 to take us over the million mark, to somewhere in the neighborhood of 1.2 million vehicles; more than enough to fulfill the president’s goal.The president’s goal has been widely criticized as far too optimistic, especially in light of the recent recession, and production problems with the Nissan Leaf (partially due to the earthquake/tsunami in Japan) one of the all electric vehicles expected to be among the leading sellers in the near future. 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.

Existence of exoplanet Fomalhaut b called into question

first_img(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.

Team develops tooth embedded sensor for oral activity recognition

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.

Analysis of remains in ancient gravesite gives insight into Neolithic history in

first_img 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.

Calendar of the untimely

first_imgThe 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.

Women across decades

first_imgStree 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.last_img read more
