At that size, 3D structures are too small to be assembled by any machine and they must be guided to assemble on their own. And now, interdisciplinary research from Johns Hopkins University and Brown University has led to a breakthrough showing that higher order polyhedra can indeed fold up and assemble themselves, creating nanostructures that may be used in drug delivery and other applications."

At first, video conferencing was used to provide therapy for patients in supervised facilities such as prisons, rural clinics, and veteran’s healthcare facilities. But the trend is expanding and now many patients are finding it easier to talk to a therapist from the comfort of their living rooms. Online psychotherapy sites dedicated to providing web-based therapy sessions are on the rise. Breakthrough.com is one such site and has enrolled 900 therapists over a two-year time span. There is also the Telemental Health Institute, an online training institution for telepsychiatry and online psychotherapy services."

Developed through joint research by Fuyo and the Saitama Medical University International Medical Center, the life size plastic body contains a blood vessel system that runs from the groin to the cerebral artery, as well as a circulation pump and pressure control circuit used to realistically simulate blood flow and pressure in the body."

RHex can operate right-side-up or up-side down, as shown in the video, and goes for up to four hours on one charge of its batteries. RHex has been around for several years, but we redesigned this version for ruggedness, long battery life, maintainability and improved mobility. This version of RHex was funded by the US Army's Rapid Equipping Force."

The idea of the graphical Windows interface, for instance, may have been based on Apple’s Macintosh interface (which may have been based on a graphical Xerox interface, depending on which story you believe). USB technology has become a part of almost every mobile device, providing power and data transfer, even though it started as primarily a method of connecting printers, keyboards and mice to desktop computers."

Nick Smith, president of the San Diego company AV Concepts that created the hologram, worked with rapper and producer Dr. Dre to accurately recreate Tupac with hologram technology."

A modified platform resembling these robots is expected to be used as government-funded equipment (GFE) for performers in Tracks B and C of the DARPA Robotics Challenge. The GFE Platform is expected to have two arms, two legs, a torso and a head, and will be physically capable of performing all of the tasks required for the disaster response scenarios scheduled in the Challenge. However, despite the appearance of the robots in the video, the Challenge is decidedly not exclusive to humanoid robot solutions. Any designs are welcome provided they are compatible with shared human-robot environments, compatible with human tools and compatible with human operators so that a human without expertise in robotics can give commands and confidently anticipate the response. It is DARPA's position that achieving true innovation in robotics, and thus success in the Robotics Challenge, will require contributions from communities beyond traditional robotics developers. Hardware, software, modeling and gaming developers are sought to link with emergency response and various science communities to devise novel solutions that enable robots to respond to disasters according to the tasks laid out in DARPA's announcement for the Challenge."

A new analysis by biologists, physicists and engineers at Brown University reveals the subtle but important degree to which that pressure has literally shaped the flapping wings of bats. The findings not only help explain why bats and some birds tuck in their wings on the upstroke, but could also help inform human designers of small flapping vehicles. The team’s research is funded by the US Air Force Office of Sponsored Research. “If you have a vehicle that has heavy wings, it would become energetically beneficial to fold the wings on the upstroke,” said Sharon Swartz, professor of ecology and evolutionary biology at Brown. She and Kenneth Breuer, professor of engineering, are senior authors on the paper."

To this end, the Naval Research Laboratory (NRL), with support from the Office of Naval Research, is conducting research and developing new technologies to enable shoulder-to-shoulder robotic damage control teammates. The robot in this video is a research platform for testing software for cognitive robotics and human-robot interactions. The knowledge gained from this research will be applied to firefighting robots used on ships. Through a combination of speech and visual recognition, the robot is able to identify trusted individuals, in this case, the human fire-fighting teammate. The human is able to provide situational information to the robot by voice and gestural commands. Here, the human partner is telling Octavia the general location of the fire before she enters the compartment. Using two infrared cameras, Octavia is able to localize the fire, allowing her to target it with the compressed air/water backpack."

The blatantly opportunistic timing of the move — given Facebook's IPO — is akin to Yahoo's attack against Google during its own IPO in 2004 and has been much decried by the online community as a villainous and vainglorious ploy to seize funds that would have been better earned by legitimate innovation rather than patent trolling. Facebook's former marketing director, Randi Zuckerberg, summed it up best with her tweet, "This Yahoo stuff feels to me like the business equivalent of when celebs do 'Dancing With The Stars' in a last-ditch effort to save a career." In response to Yahoo's attack, Facebook bolstered its 56 patents with some 'white hat' counter-trolling of Yahoo by purchasing 750 IBM patents that created a potential minefield. Armed to the teeth, Facebook today raised its blade and struck ten powerful blows in a countersuit against Yahoo."

But, might it be possible to train the brain to ‘see’ again after such an injury? Yes, according to Tony Ro, a neuroscientist at The City College of New York, who is artificially recreating a condition called Blindsight in his lab. "Blindsight is a condition that some patients experience after having damage to the primary visual cortex in the back of their brains. What happens in these patients is they go cortically blind, yet they can still discriminate visual information, albeit without any awareness." explains Ro. This research holds tantalizing clues to mapping alternative visual pathways that may one day help rehabilitate patients with damage to their primary visual cortex."
