Boston Dynamics’ Atlas robot weighs 330 pounds, but it can now balance on one leg

Atlas is back . While the robot itself may be from Google-owned Boston Dynamics, the balance algorithm is from IHMC (Institute for Human and Machine Cognition) who’s worked with the robotics company to get the six foot two biped walking better. IHMC has a strong track record in DARPA’s Robotics Challenge , coming first in computer simulations and second in real-life field trials. The next challenge comes in 2015, with more advanced trials in the summer. Turn down your speakers, then jump after the break to se a pile of motors and metal balance atop a few cinder blocks and flap its arms. There may be a beauty to its motions, but it certainly ain’t a quiet beauty. Again: mute the sound. Filed under: Robots , Google Comments Source: IHMC

Denmark Faces a Tricky Transition To 100 Percent Renewable Energy

HughPickens.com writes Justin Gillis writes in the NYT that Denmark is pursuing the world’s most ambitious policy against climate change, aiming to end the burning of fossil fuels in any form by 2050 — not just in electricity production, as some other countries hope to do, but in transportation as well. The trouble is that while renewable power sources like wind and solar cost nothing to run, once installed, as more of these types of power sources push their way onto the electric grid, they cause power prices to crash at what used to be the most profitable times of day. Conventional power plants, operating on gas or coal or uranium, are becoming uneconomical to run. Yet those plants are needed to supply backup power for times when the wind is not blowing and the sun is not shining. With their prime assets throwing off less cash, electricity suppliers in Germany and Denmark have applied to shut down a slew of newly unprofitable power plants, but nervous governments are resisting, afraid of being caught short on some cold winter’s night with little wind. “We are really worried about this situation, ” says Anders Stouge, the deputy director general of the Danish Energy Association. “If we don’t do something, we will in the future face higher and higher risks of blackouts.” Environmental groups, for their part, have tended to sneer at the problems the utilities are having, contending that it is their own fault for not getting on the renewables bandwagon years ago. But according to Gillis, the political risks of the situation also ought to be obvious to the greens. The minute any European country — or an ambitious American state, like California — has a blackout attributable to the push for renewables, public support for the transition could weaken drastically. Rasmus Helveg Petersen, the Danish climate minister, says he is tempted by a market approach: real-time pricing of electricity for anyone using it — if the wind is blowing vigorously or the sun is shining brightly, prices would fall off a cliff, but in times of shortage they would rise just as sharply.

Researchers Demonstrate Electrically Activated Micro-Muscles

mpicpp sends news of research at the University of Michigan in which a self-assembling chain of particles can be used as tiny, electrically-activated muscles. The team started with particles similar to those found in paint, with diameters of about a hundredth the width of a strand of hair. They stretched these particles into football shapes and coated one side of each football with gold. The gilded halves attracted one another in slightly salty water—ideally about half the salt concentration in the sports drink Powerade. The more salt in the water, the stronger the attraction. Left to their own devices, the particles formed short chains of overlapping pairs, averaging around 50 or 60 particles to a chain. When exposed to an alternating electric field, the chains seemed to add new particles indefinitely. But the real excitement was in the way that the chains stretched. … While the force generated by the fibers is about 1, 000 times weaker than human muscle tissue per unit area, it may be enough for microbots.

“DarkHotel” uses bogus crypto certificates to snare Wi-Fi-connected execs

DeviantArt user: Tincho555 Researchers have uncovered a seven-year-old malware operation that combines advanced cryptographic attacks, zero-day exploits, and well-developed keyloggers to target elite executives staying in luxury hotels during business trips. The attackers behind “DarkHotel,” as the advanced persistent threat has been dubbed, appear to know in advance when a targeted exec will check in and check out of a hotel. Victims are infected through a variety of methods, including bogus software updates for Adobe Flash, Google Toolbar, or other trusted software that are presented when the exec uses the hotel’s Wi-Fi or wired Internet access. In many cases, the attack code is signed with a trusted digital certificate that the attackers were able to clone by factoring the underlying 512-bit private key. While factoring weak 512-bit keys has been practical for several years, the crypto attack nonetheless is an “advanced” capability, particularly a few years ago. Taken together, the characteristics are an indication the operators have some sophistication, said researchers from Kaspersky Lab, the Russia-based security firm that disclosed the campaign. “The fact that most of the time the victims are top executives indicates the attackers have knowledge of their victims whereabouts, including name and place of stay,” the researchers wrote in a report published Monday . “This paints a dark, dangerous web in which unsuspecting travelers can easily fall. While the exact reason why some hotels function as an attacker vector are unknown, certain suspicions exist, indicating possibly a much larger compromise. We are still investigating this aspect of the operation and will publish more information in the future.” Read 6 remaining paragraphs | Comments

Tor Project Mulls How Feds Took Down Hidden Websites

HughPickens.com writes: Jeremy Kirk writes at PC World that in the aftermath of U.S. and European law enforcement shutting down more than 400 websites (including Silk Road 2.0) which used technology that hides their true IP addresses, Tor users are asking: How did they locate the hidden services? “The first and most obvious explanation is that the operators of these hidden services failed to use adequate operational security, ” writes Andrew Lewman, the Tor project’s executive director. For example, there are reports of one of the websites being infiltrated by undercover agents and one affidavit states various operational security errors.” Another explanation is exploitation of common web bugs like SQL injections or RFIs (remote file inclusions). Many of those websites were likely quickly-coded e-shops with a big attack surface. Exploitable bugs in web applications are a common problem says Lewman adding that there are also ways to link transactions and deanonymize Bitcoin clients even if they use Tor. “Maybe the seized hidden services were running Bitcoin clients themselves and were victims of similar attacks.” However the number of takedowns and the fact that Tor relays were seized could also mean that the Tor network was attacked to reveal the location of those hidden services. “Over the past few years, researchers have discovered various attacks on the Tor network. We’ve implemented some defenses against these attacks (PDF), but these defenses do not solve all known issues and there may even be attacks unknown to us.” Another possible Tor attack vector could be the Guard Discovery attack. The guard node is the only node in the whole network that knows the actual IP address of the hidden service so if the attacker manages to compromise the guard node or somehow obtain access to it, she can launch a traffic confirmation attack to learn the identity of the hidden service. “We’ve been discussing various solutions to the guard discovery attack for the past many months but it’s not an easy problem to fix properly. Help and feedback on the proposed designs is appreciated.” According to Lewman, the task of hiding the location of low-latency web services is a very hard problem and we still don’t know how to do it correctly. It seems that there are various issues that none of the current anonymous publishing designs have really solved. “In a way, it’s even surprising that hidden services have survived so far. The attention they have received is minimal compared to their social value and compared to the size and determination of their adversaries.” Read more of this story at Slashdot.
