astroengine writes "Extrapolating from findings by NASA's planet-hunting Kepler Space Telescope, scientists on Wednesday said roughly six percent of so-called red dwarf stars have Earth-sized planets properly positioned around their parent stars so that liquid water could exist on their surfaces. The team looked at 95 candidate planets circling red dwarf stars observed by Kepler and found that at least 60 percent have planets smaller than Neptune. Most were not the right size or temperature to be Earth-like, but three were found to be both warm and approximately Earth-sized. Statistically that would mean six percent of all red dwarf stars should have a Earth-sized planet. Since 75 percent of the closest stars are red dwarfs, the nearest Earth-like world may be just 13 light-years away."

First time accepted submitter ios and web coder writes "From the article: 'A dizzying story that involves falsified medical research, plagiarism, and legal threats came to light via a DMCA takedown notice today. Retraction Watch, a site that followed (among many other issues) the implosion of a Duke cancer researcher's career, found all of its articles on the topic pulled by WordPress, its host. The reason? A small site based in India apparently copied all of the posts, claimed them as their own, then filed a DMCA takedown notice to get the originals pulled from their source. As of now, the originals are still missing as their actual owners seek to have them restored.' This is extremely worrying. Even though the original story is careful not to make accusations, I will. This sure smells like a 'Reputation Defense' dirty trick."
Layzej writes "Last summer a paper investigating the link between conspiratorial thinking and the rejection of climate science provoked a response on blogs skeptical of the scientific consensus that appeared to illustrate the very cognitive processes at the center of the research. This generated data for a new paper titled 'Recursive fury: Conspiracist ideation in the blogosphere in response to research on conspiracist ideation (PDF).' The researchers reviewed the reactions for evidence of conspiratorial thinking, including the presumption of nefarious intent, perception of persecution, the tendency to detect meaning in random events, and the ability to interpret contrary evidence as evidence that the conspiracy is even greater in scope that was originally believed. Some of the hypotheses promoted to dismiss the findings of the original paper ultimately grew in scope to include actors beyond the authors, such as university executives, a media organization, and the Australian government. It is not clear whether the response to this paper will itself provide data for further research, or how far down this recursion could progress. I fear the answer may be 'all the way.'"
An anonymous reader writes "In decades and centuries past, scientific genius was easy to quantify. Those scientists who were able to throw off the yoke of established knowledge and break new ground on their own are revered and respected. But as humanity, as a species, has gotten better at science, and the basics of most fields have been refined over and over, it's become much harder for any one scientist to make a mark on the field. There's still plenty we don't know, but so much of it is highly specialized that many breakthroughs are understood by only a handful. Even now, the latest generation is more likely to be familiar with the great popularizers of science, like Neil deGrasse Tyson, Bill Nye, and Carl Sagan, than of the researchers at the forefront of any particular field. "...most scientific fields aren't in the type of crisis that would enable paradigm shifts, according to Thomas Kuhn's classic view of scientific revolutions. Simonton argues that instead of finding big new ideas, scientists currently work on the details in increasingly specialized and precise ways." Will we ever again see a scientist get recognition like Einstein did?"
With his trademark hat and beard, Dr. Robert Bakker is one of the most recognized paleontologists working today. Bakker was among the advisers for the movie Jurassic Park, and the character Dr. Robert Burke in the film The Lost World: Jurassic Park is based on him. He was one of the first to put forth the idea that some dinosaurs had feathers and were warm-blooded, and is credited with initiating the ongoing "dinosaur renaissance" in paleontology. Bakker is currently the curator of paleontology for the Houston Museum of Natural Science and the Director of the Morrison Natural History Museum in Colorado. He is also a Christian minister, who contends that there is no real conflict between religion and science, citing the writings and views of Saint Augustine as a guide on melding the two. Dr. Bakker has agreed to take some time from his writing and digging in order to answer your questions. As usual, ask as many questions as you'd like, but please, one question per post.
An anonymous reader writes with news from Mersenne.org, home of the Great Internet Mersenne Prime Search: "On January 25th at 23:30:26 UTC, the largest known prime number, 257,885,161-1, was discovered on GIMPS volunteer Curtis Cooper's computer. The new prime number, 2 multiplied by itself 57,885,161 times, less one, has 17,425,170 digits. With 360,000 CPUs peaking at 150 trillion calculations per second, GIMPS — now in its 17th year — is the longest continuously-running global 'grassroots supercomputing' project in Internet history."
MTorrice writes "To make light-weight, inexpensive electronics using renewable materials, scientists have turned to a technology that is almost 2,000 years old: paper. Researchers fabricated organic transistors on a transparent, exceptionally smooth type of paper called nanopaper. This material has cellulose fibers that are only 10 nm in diameter. The nanopaper transistors are about 84% transparent, and their performance decreases only slightly when bent."
MatthewVD writes "In 2006, researcher Mark Changizi came up with a novel theory for why humans evolved with color vision: to detect social cues and emotions in others. He built glasses called 02Amps to enhance perception of blood pooling. Some hospitals have tried using the glasses to see bruising that's not visible unaided, or help nurses find veins. But it turns out now that the glasses might be able to fix some forms of colorblindness, too."
cylonlover writes with news of an update to the model used for calculating the habitable zone around stars shifting things out a bit. From the article: "Researchers at Penn state have developed a new method for calculating the habitable zone (original paper, PDF) around stars. The computer model based on new greenhouse gas databases provides a tool to better estimate which extrasolar planets with sufficient atmospheric pressure might be able to maintain liquid water on their surface. The new model indicates that some of the nearly 300 possible Earth-like planets previously identified might be too close to their stars to to be habitable. It also places the Solar System's habitable zone between 0.99 AU (92 million mi, 148 million km) and 1.70 AU (158 million mi, 254 million km) from the Sun. Since the Earth orbits the Sun at an average distance of one AU, this puts us at the very edge of the habitable zone."
carmendrahl writes "Emergency-room visits linked to caffeine-laden energy drinks are on the rise. This gives scientists who'd like to see caffeine regulated the jitters. But the U.S. Food and Drug Administration seems to be dragging its feet on regulating caffeine content in food and drink, because people have different sensitivities to it (abstract). Currently, caffeine-rich products like Monster Energy get around the rules because they're marketed as dietary supplements. 'Caffeine gets cleared from the body at different rates because of genetic variations, gender, and even whether a person is a smoker. For this reason, it’s difficult to set a safe limit of daily consumption on the compound. Physiological differences, as well as differences in the way people consume caffeine, have tied FDA in knots as it has debated how to regulate the substance. ... The toxic level in humans, about 10 g, is roughly the equivalent of imbibing 75 cups of brewed coffee (in 8-oz mugs) or 120 cans of Red Bull over a few hours. But that lethal limit can vary widely from person to person, experts say."

An anonymous reader writes "Iran has unveiled a new home-made combat aircraft, which officials say can evade radar. The single-seat Qaher F313 (Dominant F313) is the latest design produced by Iran's military since it launched the Azarakhsh (Lightning), in 2007. President Mahmoud Ahmedinejad said it had 'almost all the positive features' of the world's most sophisticated jets.Footage from state TV showed the jet in flight, but not its take-off or landing."
First time accepted submitter ras writes "The Reserve Bank of Australia did some investigation into the accuracy of their economic predictions — the ones they use to run the country — with less than flattering results. '70 per cent of the RBA's forecasts for underlying inflation for the year ahead were close to the mark, but its predictions of economic growth were less accurate, and its unemployment rate estimates no better than [chance] ... The Reserve Bank employs numbers of people on very high pay and what they're admitting now is that their — all of this so-called science — has produced nothing more than what a roll of the dice could produce.'"
An anonymous reader writes "NASA is trying to measure the air pollution by flying a plane at various altitudes over the bay area. The tests are a part of a larger effort led by the DISCOVER-AQ campaign — a multi-year program launched across the United States in 2011 by NASA's Langley Research Center in Hampton, Virginia. DISCOVER-AQ stands for Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality. NASA's Langley Research Center in Hampton, Va., is the lead center for the mission."
Shipud writes "We live in the post-genomic era, when DNA sequence data is growing exponentially. However, for most of the genes that we identify, we have no idea of their biological functions. They are like words in a foreign language, waiting to be deciphered. The Critical Assessment of Function Annotation, or CAFA, is a new experiment to assess the performance of the multitude of computational methods developed by research groups worldwide and help channel the flood of data from genome research to deduce the function of proteins. Thirty research groups participated in the first CAFA, presenting a total of 54 algorithms. The researchers participated in blind-test experiments in which they predicted the function of protein sequences for which the functions are already known but haven't yet been made publicly available. Independent assessors then judged their performance. The challenge organizers explain that: 'The accurate annotation of protein function is key to understanding life at the molecular level and has great biochemical and pharmaceutical implications, explain the study authors; however, with its inherent difficulty and expense, experimental characterization of function cannot scale up to accommodate the vast amount of sequence data already available. The computational annotation of protein function has therefore emerged as a problem at the forefront of computational and molecular biology.'"
