Festo's Drone Dragonfly Takes To the Air 45

Posted by samzenpus from the little-flyer dept.
yyzmcleod writes "Building on the work of last year's bionic creation, the Smart Bird, Festo announced that it will literally launch its latest creation, the BionicOpter, at Hannover Messe in April. With a wingspan of 63 cm and weighing in at 175 grams, the robotic dragonfly mimics all forms of flight as its natural counterpart, including hover, glide and maneuvering in all directions. This is made possible, the company says, by the BionicOpter's ability to move each of its four wings independently, as well as control their amplitude, frequency and angle of attack. Including its actuated head and body, the robot exhibits 13 degrees of freedom, which allows it to rapidly accelerate, decelerate, turn and fly backwards."

Misconfigured Open DNS Resolvers Key To Massive DDoS Attacks 179

Posted by Unknown Lamer from the check-your-sources dept.
msm1267 writes with an excerpt From Threat Post: "While the big traffic numbers and the spat between Spamhaus and illicit webhost Cyberbunker are grabbing big headlines, the underlying and percolating issue at play here has to do with the open DNS resolvers being used to DDoS the spam-fighters from Switzerland. Open resolvers do not authenticate a packet-sender's IP address before a DNS reply is sent back. Therefore, an attacker that is able to spoof a victim's IP address can have a DNS request bombard the victim with a 100-to-1 ratio of traffic coming back to them versus what was requested. DNS amplification attacks such as these have been used lately by hacktivists, extortionists and blacklisted webhosts to great success." Running an open DNS resolver isn't itself always a problem, but it looks like people are enabling neither source address verification nor rate limiting.

Uniloc Patent Case Against Rackspace Tossed for Bogus Patents 76

Posted by Unknown Lamer from the don't-mess-with-red-hat dept.
netbuzz writes "A federal judge in Texas, presiding over a district notorious for favoring patent trolls, has summarily dismissed all claims relating to a case brought by Uniloc USA against Rackspace for [Linux] allegedly infringing upon [Uniloc's] patents. Red Hat defended Rackspace in the matter and issued a press release saying: 'In dismissing the case, Chief Judge Leonard Davis found that Uniloc's claim was unpatentable under Supreme Court case law that prohibits the patenting of mathematical algorithms. This is the first reported instance in which the Eastern District of Texas has granted an early motion to dismiss finding a patent invalid because it claimed unpatentable subject matter.'" You can't patent floating point math after all.

Building Better Body Armor With Nanofoams 74

Posted by samzenpus from the protect-ya-neck dept.
Zothecula writes "Given that scientists are already looking to sea sponges as an inspiration for body armor, perhaps we shouldn't be surprised that foam is also being considered ... not just any foam, though. Unlike regular foam, specially-designed nanofoams could someday not only be used in body armor, but also to protect buildings from explosions."

Hands-on With the Wii MotionPlus 153

Posted by Soulskill from the high-fidelity-waggling dept.
Parz writes "In June, Nintendo will be releasing a peripheral called MotionPlus. This small device attaches to the bottom of the Wii-mote and acts as a more sophisticated motion-sensor to the controller as it currently stands. Its goal is to bring greater parity between a user's movements and the animations that they bring to life on-screen. Gameplayer got some hands-on time with the device, and they are extremely impressed." The MotionPlus will only affect new games; Nintendo has said they have no plans to add support for older titles. Virtua Tennis 2009 will be the first game to support it, and Eurogamer has a look at the game both with and without the MotionPlus.

Submission + - SPAM: Skin-based display screens from nanotech "tatt 1

destinyland writes: "Rensselaer Polytechnic Institute in New York is developing flexible nanotubes inserted under the skin to create a handheld display — inside your hand. They wirelessly receive data and display reminders and text messages, and the concept has also been broadened to suggest endlessly programmable digital tattoos, while Netherlands-based Royal Philips Electronics is also exploring the concept of the body as "a platform for electronics and interactive skin technologies.""

Submission + - Chimpanzees exchange meat for sex (bbc.co.uk)

Submitted by
the_therapist
the_therapist writes: "A team from the Max Planck Institute for Evolutionary Anthropology in Germany, studied chimps in the Tai Forest reserve in Ivory Coast and discovered that chimpanzees enter into "deals" whereby they exchange meat for sex.

Among the findings are that "male chimps that are willing to share the proceeds of their hunting expeditions mate twice as often as their more selfish counterparts". They also found this to be "a long-term exchange, so males continue to share their catch with females when they are not fertile, copulating with them when they are"."

Submission + - Cells in the Retina Tile Like Puzzle Pieces (sciencedaily.com)

Submitted by tim
tim writes: Recent work at the Salk Institute in La Jolla, Calif. shows that cells in the retina sample visual space like a multi-layered jigsaw puzzle. High resolution measurements of light response reveal that individual cells have irregular shapes, but together their shapes coordinate to tightly cover visual space. This type of large scale, exquisite coordination could be a general organizing principle of the brain, but no one has seen it previously because technical obstacles typically prevent recording from large cell populations. The full paper can be found here.
