KentuckyFC writes "Earlier this year, Paris-based Aldebaran-Robotics picked up $8 million in venture capital funding to help commercialize its NAO humanoid robot. The target market for this device is research labs working on the next generation of robotic hardware and software. Today, the company has posted a detailed spec of NAO on the arXiv saying that it expects the robot to cost about $15,000 each. That's cheap compared to other humanoids. Fuitsu's HOAP humanoids cost $50,000 each and various estimates price Honda's Asimo at $1 million per bot, although they are not for sale. Aldebaran-Robotics says that NAO's cost should come down to about $6,000 as production ramps up."

oliderid writes "The first official image of a Russian-European manned spacecraft has been unveiled. It is designed to replace the Soyuz vehicle currently in use by Russia and will allow Europe to participate directly in crew transportation.The reusable ship was conceived to carry four people towards the Moon, rivaling the US Ares/Orion system. This project is the Plan A for the European Space agency. The plan B is an evolution of the ATV proposed by a consortium of European companies led by Astrium."

Geoffrey.landis writes "Some of you may have heard me talk about colonizing Venus. Well, for those who haven't, Universe Today is running story about floating cities on Venus. It's a reasonable alternative for space colonies — after all, the atmosphere of Venus (at about 50 km) is the most Earth-like environment in the solar system (other than Earth, of course). '50 km above the surface, Venus has air pressure of approximately 1 bar and temperatures in the 0C-50C range, a quite comfortable environment for humans. Humans wouldn't require pressurized suits when outside, but it wouldn't quite be a shirtsleeves environment. We'd need air to breathe and protection from the sulfuric acid in the atmosphere.'"

Raver32 writes "A team of astronomers announced they have discovered the smallest and potentially most Earth-like extrasolar planet yet. Five times as massive as Earth, it orbits a relatively cool star at a distance that would provide earthly temperatures as well, signaling the possibility of liquid water. 'The separation between the planet and its star is just right for having liquid water at its surface,' says astronomer and team spokesperson Stephane Udry of the Observatory of Geneva in Versoix, Switzerland. 'That's why we are a bit excited.' But researchers do not yet know if the planet contains water, if it is truly rocky like Earth, which might make it hospitable to life as we know it, or whether it is blanketed by a thick atmosphere. 'What we have,' Udry says, 'is the minimum mass of the planet and its separation" from its star.'"

phantomflanflinger writes "The Cern Laboratory, home of the Large Hadron Collider, is fast becoming one of the coolest places in the Universe. According to news.bbc.co.uk, the Large Hadron Collider is entering the final stages of being lowered to a temperature of 1.9 Kelvin (-271C; -456F) — colder than deep space. The LHC aims to re-create the conditions just after the Big Bang and continue the search for the Higgs boson."

chareverie writes "Researchers at Harvard University have been working towards a goal of replacing some types of heart surgery with injections of cells that would grow into blood vessels for damaged hearts. The cells that would be used are progenitor cells obtained from the blood or bone marrow, as opposed to stem cells that are obtained from human embryos. The research team was successful with their tests on growing heart blood vessels in mice. Joyce Bishoff, an associate professor of medicine at Harvard and senior author of the report, says, 'Our next goal down the line is to use them in humans.' She also notes that more studies need to be done on animals to see how these cells would react and behave with other types of tissues. A similar human experiment was done two years ago in Germany, during which a few people from a group of 75 heart attack victims were given injections of progenitor cells from their own bone marrow or blood. The report concluded that there were improved heart functions." Reader w1z4rd points out related coverage with some more information at BBC News.

Geoffrey.landis writes "A Purdue University panel investigated allegations against nuclear engineering professor Rusi Taleyarkhan, finding that he had in fact committed scientific misconduct in his work. Taleyarkhan had published papers in which he reported seeing evidence of nuclear fusion in the collapse of tiny bubbles in a liquid subjected to ultrasonic excitation — a finding that would be groundbreaking, if true, but one that apparently could not be replicated by other researchers. The allegations against Taleyarkhan were made in March of 2006. A local Indiana paper gives the full list of allegations against Taleyarkhan, and the resolution of each by the panel. The full report (PDF) is also available. Of the nine specific allegations, only two were found to comprise scientific misconduct. The committee 'could not find any other instances of scientists being able to replicate Taleyarkhan's results without Taleyarkhan having direct involvement with the experiments,' but notes that this comes 'just short of questioning whether Taleyarkhan's results were fraudulent.'" We've discussed this gentleman's work and the scrutiny it has received several times, and members of the scientific community seem to have given him the benefit of the doubt in many cases.

no1home writes "There is a story at Discovery Channel's site about a new utility for mapping disease. The premise is to have bots crawl the web looking for stories about disease outbreaks and log them onto a map. '"We were originally thinking about how we could expand disease surveillance and pick up outbreaks earlier than traditional methods," said John Brownstein of Harvard Medical School and Children's Hospital Boston, who created HealthMap in September of 2006 with Clark Friefeld, a software developer at Harvard Medical School.' But then it was noticed by Google.org and has since grown into its own website, HealthMap Global disease alert map, and claims to be able to identify 95% of all disease outbreaks, some of them before WHO or CDC."

Statesman writes "The Los Angeles Times reports that an Arizona crime lab technician found two felons with remarkably similar genetic profiles, so similar that they would ordinarily be accepted in court as a match, but one felon was black and the other white. The FBI estimated the odds of unrelated people sharing those genetic markers to be as remote as 1 in 113 billion. Dozens of similar matches have been found, and these findings raise questions about the accuracy of the FBI's DNA statistics. Scientists and legal experts want to test the accuracy of official statistics using the nearly 6 million profiles in CODIS, the national system that includes most state and local databases. The FBI has tried to block distribution of the Arizona results and is blocking people from performing similar searches using CODIS. A legal fight is brewing over whether the nation's genetic databases ought to be opened to wider scrutiny. At stake is the credibility of the odds often cited in DNA cases, which can suggest an all but certain link between a suspect and a crime scene."

Cowards Anonymous points out news that studies based on data from the Mars Reconnaissance Orbiter have found that vast regions of Mars contained rivers and lakes when the planet was young. The studies also suggest that the water existed for quite some time, often in standing pools, which are conducive to the formation of basic organic matter. NASA provides a color-enhanced photo of a delta within a crater. Quoting: "The clay-like minerals, called phyllosilicates, preserve a record of the interaction of water with rocks dating back to what is called the Noachian period of Mars' history, approximately 4.6 billion to 3.8 billion years ago. This period corresponds to the earliest years of the solar system, when Earth, the moon and Mars sustained a cosmic bombardment by comets and asteroids. Rocks of this age have largely been destroyed on Earth by plate tectonics. They are preserved on the moon, but were never exposed to liquid water. The phyllosilicate-containing rocks on Mars preserve a unique record of liquid water environments possibly suitable for life in the early solar system."

schliz writes to mention that a team of quantum physicists have demonstrated how to significantly reduce the effects of "stiction," or the tendency for two very small, very close objects to stick together as a result of Casimir force. "'The Casimir force might be one of the many reasons that very small, movable components in micromechanical devices sometimes stick together,' said Ho Bun Chan, a assistant professor of physics at the University of Florida who is researching the Casimir force. 'The Casimir effect increases rapidly as the separation between components decreases. It becomes significant when the separation is reduced to below about 400 nm,' he told iTnews."

krygny writes "NASA's Deep Impact spacecraft (whose extended mission is called EPOXI) has created a video of the moon transiting Earth as seen from 31 million miles away. Scientists are using the video to develop techniques to study alien worlds. 'Our video shows some specific features that are important for observations of Earth-like planets orbiting other stars,' said Drake Deming of NASA's Goddard Space Flight Center... 'A "sun glint'" can be seen in the movie, caused by light reflected from Earth's oceans, and similar glints to be observed from extrasolar planets could indicate alien oceans. Also, we used infrared light instead of the normal red light to make the color composite images, and that makes the land masses much more visible.'" Here are links to the two videos, one red-green-blue and the other infrared-green-blue.

jmcbain tips a fascinating interview in Scientific American with a professor of kinesiology and neuroscience (and a 26-year practitioner of Chito-Ryu karate-do). The question was, how much training would it take for a normal person to become Batman? The professor says: "You could train somebody to be a tremendous athlete and to have a significant martial arts background, and also to use some of the gear that he has, which requires a lot of physical prowess... In terms of the physical skills to be able to defend himself against all these opponents all the time, I would benchmark that at 10 to 12 years." The problem is, even after that amount of training, no one could remain on top of their game for more than a few years. And "Batman can't really afford to lose. Losing means death — or at least not being able to be Batman anymore."
