An anonymous reader writes "For the first time, the Army has set up a project office, just for building videogames. The military has been training troops with games for decades, of course. But this is the first wing of the armed forces dedicated exclusively for gaming. One of the first projects: a tool kit that would let soldiers "build and customize their own training scenarios — just like the Marines' did, adapting Armed Assault for military purposes."

coondoggie writes "While the skies aren't exactly buzzing with unmanned aerial vehicles (UAVs) just yet, experts are warning their explosive growth will require military and public officials to address the issue sooner than they might think. The four chiefs of service aviation and intelligence, surveillance and reconnaissance (ISR) branches told the Army Aviation Association of America's unmanned aircraft symposium last week that the military should crystallize combat air control regarding UAVs, while domestic authorities must work out access and use of UAVs in domestic airspace. "I'm surprised we haven't had a collision yet," said Rear Adm. Joseph Aucoin, director of the Navy's aviation plans and requirements branch."

josmar52789 wrote with an article from the New York Times, discussing Microsoft's new push into the consumer health care market. The plan is to offer personal health care records online via a system called HealthVault. Numerous big names in the medical field have signed up for the service, including the 'American Heart Association, Johnson & Johnson LifeScan, NewYork-Presbyterian Hospital, the Mayo Clinic and MedStar Health'. The ultimate purpose of the service is to provide an online accessible but highly secure service to patients and medical facilities: "The personal information, Microsoft said, will be stored in a secure, encrypted database. Its privacy controls are set entirely by the individual, including what information goes in and who gets to see it. The HealthVault searches are conducted anonymously and will not be linked to any personal information in a HealthVault personal health record. Microsoft does not expect most individuals to type in much of their own health information into the Web-based record. Instead, the company hopes that individuals will give doctors, clinics and hospitals permission to directly send into their HealthVault record information like medicines prescribed or, say, test results showing blood pressure and cholesterol levels.

mikesd81 writes that the Mercury News reports that scientists at UC Davis have discovered that some eels have an extra set of jaws deep in their throats that launch forward into their mouths to help pull prey in. "'It looks like a funny pair of forceps with curved sharp teeth,' said evolutionary biologist Rita Mehta, lead author of the research, which appears Thursday in Nature. Before the discovery, scientists thought that all aquatic predators swallowed their prey using suction. By dropping the lower jaw and creating a flow of water into their mouths, they draw in the prey. The two species of moray eels studied by Mehta and Wainwright are the first examples of an alternative feeding method. Instead of sucking, one of these eels bites its prey with its primary set of teeth. It then draws the second set of teeth into its mouth by contracting long muscles. The secondary jaws clamp down on the prey, allowing the eel to move its primary jaws forward in a gulping motion to take in more of the prey. The two sets of jaws take turns until the whole animal has been swallowed." mikesd81 adds a link to a YouTube video of an eel eating, noting "If you look closely right around 34 seconds you can see what looks like the other set of jaws chewing."

lottameez recommends an article in the Washington Post about recent research into the persistence of myths. In short: once a myth has been put out there (e.g., "Saddam Hussein plotted the 9/11 attacks"), denying it can paradoxically reinforce its staying power. Ignoring it doesn't work either — a claim that is unchallenged gains the ring of truth. Over time, "negation tags" fall out of memory: "Saddam didn't plan 9/11" becomes "Saddam planned 9/11." From the article: "The conventional response to myths and urban legends is to counter bad information with accurate information. But the new psychological studies show that denials and clarifications, for all their intuitive appeal, can paradoxically contribute to the resiliency of popular myths... The research is painting a broad new understanding of how the mind works. Contrary to the conventional notion that people absorb information in a deliberate manner, the studies show that the brain uses subconscious 'rules of thumb' that can bias it into thinking that false information is true. Clever manipulators can take advantage of this tendency."

eldavojohn writes "Scientists in China have announced finding the gene that makes us human. The article explains that prior work has shown that humans, as compared with the great apes from which we diverged over 5 million years ago, have a longer form of a protein (type II neuropsin) located in the pre-frontal cortex of the brain. From the article: 'Gene sequencing revealed a mutation specific to humans that triggers a change in the splicing pattern of the neuropsin gene, creating a new splicing site and a longer protein. Introducing this mutation into chimpanzee DNA resulted in the creation of type II neuropsin. "Hence, the human-specific mutation is not only necessary but also sufficient in creating the novel splice form," the authors state.' The team is urging further analysis of the extra 45 amino acids in type II neuropsin since they believe that chain may cause protein structural and functional changes. The research didn't link anything with this protein, simply identifying it as a very distinct difference between us and our closest cousins."

Julio Ojeda-Zapata writes "Google on Tuesday will release a Mac version of Google Desktop. This software, like the PC version, indexes the content of a hard drive and serves it up on familiar Google-style search-result Web pages (or via a its own drop-down results list, if you prefer). But Google Desktop for the Mac is streamlined compared to the busy, gadget-y Windows version, which isn't necessarily a bad thing. The focus is squarely on search — including local indexing of an online Gmail account of your choice. It will also index your iDisk."

David DelMonte writes "Space.com is reporting on the discovery of seven dark spots near the Equator on Mars. The thinking is that these are cave openings. The openings are the size of football fields, and one of them is thought to extend approximately 400 feet below the surface.'The researchers hope the discovery will lead to more focused spelunking on Mars. "Caves on Mars could become habitats for future explorers or could be the only structures that preserve evidence of past or present microbial life ," said Glenn Cushing of Northern Arizona University, who first spotted the black areas in the photographs.'"

Nonfinity writes "A public iris scanning device has been proposed in a patent application from Sarnoff Labs in New Jersey. The device is able to scan the iris of the eye without the knowledge or consent of the person being scanned. The device uses multiple cameras, captures multiple images, and then selects the best image to process."

Several readers wrote in to tell us, following up on the recent story of the shutting down of Hubble's main camera, that program engineers are now saying that the camera is probably gone for good. The trouble resulted from a short circuit on Saturday in Hubble's most popular instrument, the Advanced Camera for Surveys. NASA engineers reported Monday that most of the camera's capabilities, including the ability to take the sort of deep cosmic postcards that have inspired the public, had probably been lost. We'll be pining for more of those amazing images until the James Webb launches in 2013.
Update: 01/30 23:28 GMT by KD : Reader Involved astronomer wrote in with an addendum / clarification to this story: "I'm a grant-funded astronomer at the Space Telescope Science Institute (www.stsci.edu) in Baltimore. I am very concerned that the article conveys the wrong idea about HST. While HST's science capacity is diminished with the loss of ACS, HST lives on and will continue to produce world-class science, even before its servicing mission in Sept. 2008, which will upgrade the instrument suite with the most sophisticated imagers in history."

unchiujar writes to mention a BBC article about the design of the first flying dinosaurs. These possible early ancestors of avians apparently resembled biplanes in many ways, with legs hanging down in a fashion similar to WWI fighters. The researchers who made this discovery use this to argue the 'trees down' model of flight evolution, but the article points out this design may possibly be a failed evolutionary experiment. From the article: "Dr Chatterjee, from Texas Tech University in Lubbock, US, explained that two lines of evidence had led the team to this conclusion. Firstly, the researchers argue, dinosaurs and birds move their legs in a vertical plane, not sideways as the tandem flight pattern requires. Secondly, the feathers on Microraptor's hind legs are asymmetrical; one of the two vanes that extend either side of the shaft is narrower than the other. Aerodynamically, the narrow leading edge of these feathers should face forward in flight, against the direction of airflow. This would have given the flying reptiles lift. "

The technique, called Prototype Hijacking, allows an attacker to redefine any feature of Javascript. The paper is called 'Subverting AJAX' (pdf), and outlines a possible Web Worm that lives in the very fabric of Web 2.0 and could kill the Web as we know it."

[TheBORG] writes "A tiny skeleton from the Early Cretaceous shows an embryonic or newborn reptile with two heads and two necks, called axial bifurcation ('two-headedness') (a well-known developmental flaw among reptile species today such as turtles and snakes) was found in China by French and Chinese paleontologists recovered from the Yixian Formation, which is nearly 150 million years old."

phil reed writes "University of Washington physicist John Cramer is attempting to send a signal back through time." From the article: "We're going to shoot an ultraviolet laser into a (special type of) crystal, and out will come two. lower-energy photons that are entangled," Cramer said. For the first phase of the experiment, to be started early next year, they will look for evidence of signaling between the entangled photons. Finding that would, by itself, represent a stunning achievement. Ultimately, the UW scientists hope to test for retrocausality — evidence of a signal sent between photons backward in time. The test will involve sending one of the photons down 10 miles of fiber optic cable, delaying it by 50 microseconds, then testing a quantum-mechanical aspect of the delayed photon. Due to quantum entanglement, the non-delayed photon would need to reflect the measurement made 50 microseconds later on the delayed photon. In order for this to happen, some kind of signal would need to be sent 50 microseconds back in time from the delayed photon to the non-delayed photon. (Confusing? Quantum physics is like that.)
