The Land Walker: the world's first 340cm bipedal exoskeleton - 0 views

  •  
    Japanese machinery and robotics manufacturer Sakakibara-Kikai has released the first genuine bi-pedal exoskeleton - a landmark event and one which is certain to attract a lot of attention for the company. Mechanatrons and BattleMechs have long been the subject of scifi books, comics and movies with the promise of cyborg technology popularised by the smash sixties television series "The Six Million Dollar Man." We've previously seen some celebrated exoskeletons in films such as Alien (Sigourney Weaver's Ripley takes out the Queen alien in an exoskeleton), Star Wars (the AT-ST Imperial Scout Walker) and RoboCop (the ED209), but until now, the nearest thing we've seen in the metal was the 3.5 metre superhero exoskeleton Enryu from Tmsuk in Japan. Sakakibara-Kikai's Land Walker is just a tad shorter than Enryu at 3.4 metres, weighs 1000kg and shuffles along at 1.5kmh. Enryu is a lot faster than Land Walker but uses caterpillar-like tracks rather than legs to perform its chores - the strapping 3.5 metre Enryu will be called upon to rush into burning buildings, lift heavy objects and rescue people.

Ain't No Science Fiction, Suspended Animation Is FDA Approved and Heading To Clinical T... - 0 views

  • The Food and Drug Administration has already approved his technique for human trials, and he has secured funding from the Army to conduct the feasibility phase. Dr. Rhee is currently lobbying for funds to conduct a full trial. If he’s successful human trials could begin as early as next year.
  • What Dr. Rhee hopes to test on humans is a method he worked out for the past couple decades on pigs. Patients would be injected with a cold fluid to induce severe hypothermia. Clinically hypothermia is characterized by the drop of a person’s body temperature from its normal 98.6 degrees Fahrenheit (37 degrees Celcius) to lower than 95 degrees (35 C). Below 95, the heart, nervous system and other organs begin to fail. The strict range is indicative of a metabolic system with strict temperature requirements for proper function (death waits only a few degrees the other way as well). Dr. Rhee’s method involves injecting patients with a cold fluid that would bring the body’s temperature down to 50 degrees Fahrenheit (10 C). Sounds chilling, but when he induced the extreme hypothermia in pigs they came out just fine. Heart function, breathing, and brain function was completely normal.
  • Dr. Rhee is no stranger to high-stakes medicine. The native South Korean was trained at the Uniformed Services University Medical School in Bethesda, Maryland. Following a fellowship in trauma and critical care at the University of Washington’s Harborview Medical Center he served in the US Navy as director of the University of South California’s Navy Trauma Training Center at Los Angeles County. He was then sent to Afghanistan where he was one of the first surgeons at Camp Rhino. Later he started the first surgical unit at Ramadi, Iraq. His cool under fire was on display nationally as he performed surgery on US Representative Gabrielle Giffords after she was shot through the skull in the Tucson shootings this past January. His experience with induced hypothermia came into play the night of the shootings when Dr. Rhee removed part of the congresswoman’s skull. The wound had raised her body temperature and began “cooking the brain.” He used a device to cool Rep. Giffords’ skin.

So What Can The Music Industry Do Now? | Techdirt - 0 views

  • The past was, and the future is going to be, much more about performance. In this new world, recordings often function as more as ads for concerts than as money-makers themselves. (And sometimes are bundled with concert tickets, as Madonna's latest album was.) As a result, copying looks a lot less fearsome. A copied ad is just as effective--and maybe much more so--than the original.
  • Just ask pop singer Colbie Caillat. Caillet's music career began in 2005 when a friend posted several of her home-recorded songs to MySpace. One song, Bubbly, began to get word of mouth among MySpace users, and within a couple of months went viral. Soon Colbie Caillat was the No. 1 unsigned artist on MySpace. Two years after posting Bubbly, Caillet had more than 200,000 MySpace friends, and her songs had been played more than 22 million times. Caillet had built a global fan base while never leaving her Malibu home. In 2007, Universal Records released her debut album, Coco, which peaked at No. 5 on the Billboard charts and reached platinum status.
  • The problem of piracy in music is, of course, very different from the problem in comedy. Stand-up comics worry most about a rival, not a fan, copying their jokes. Still, the reduction of consumer copying of music via norms may be possible, and will become more imaginable if the music industry experiences ever-greater fragmentation and communication. There is already an interesting example of norms playing a substantial role in controlling copying in music. In the culture of jambands, we see the fans themselves taking action to deter pirates. What are jambands? In a fascinating 2006 paper, legal scholar Mark Schultz studied the unique culture of a group of bands that belong to a musical genre, pioneered by the Grateful Dead, characterized by long-form improvisation, extensive touring, recreational drug use, and dedicated fans. Although acts like Phish, Blues Traveler, and the Dave Mathews Band vary in their styles, they are all recognizably inspired by the progenitors of jam music, the Dead. But the Dead's influence is not only musical. Most jambands adhere to a particular relationship with their fans that also was forged by the Dead.

  • it turns out that by killing the single, the record labels made the Internet piracy problem, when it arrived, even worse. One of the major attractions of filesharing was that it brought back singles. Consumers wanted the one or two songs on the album that they liked, and not the ten they didn't.

Uroburos Rootkit: Most sophisticated 3-year-old Russian Cyber Espionage Campaign - The ... - 0 views

  • The researchers claimed that the malware may have been active for as long as three years before being discovered and appears to have been created by Russian developers.
  • The two main components of Uroburos are - a driver and an encrypted virtual file system, used to disguise its nasty activities and to try to avoid detection. Its driver part is extremely complex and is designed to be very discrete and very difficult to identify.
  • The virtual file system can’t be decrypted without the presence of drivers, according to the Gdata’s analysis explained in the PDF.
  • ...2 more annotations...
  • we assume that the group behind Uroburos is the same group that performed a cyberattack against the United States of America in 2008 with a malware called Agent.BTZ
  • The attacks carried out with Uroburos are targeting government institutions, research institutions, intelligence agencies, nation states, research institutions or companies dealing with sensitive information as well as similar high-profile targets. The oldest drivers identified by the researchers was compiled in 2011 is the evidence that the malware was created around three years ago and was undetected.

Keurig Will Use DRM In New Coffee Maker To Lock Out Refill Market | Techdirt - 0 views

  • The plan was confirmed by Keurig's CEO who stated on a recent earnings call that the new maker indeed won't work with "unlicensed" pods as part of an effort to deliver "game-changing performance." "Keurig 2.0" is expected to launch this fall. French Press and pour-over manufacturers like Chemex have plenty of time to get their thank you notes to Keurig in the mail ahead of time as users are hopefully nudged toward the realization they could be drinking much better coffee anyway

Ask Ethan #55: Could a Manned Mission to Mars Abort? - Starts With A Bang! - Medium - 0 views

  • No humans have ever traveled farther away from Earth than the crew of Apollo 13 did, as they circled around the far side of the Moon close to lunar apogee, achieving a maximum distance of 400,171 km above the Earth’s surface on April 15, 1970. But when the first manned spaceflight to another planet occurs, that record will be shattered, and in a mere matter of days.
  • The way we currently reach other worlds with our present technology — or any remote location in the Universe — involves three distinct stages:The initial launch, which overcomes the Earth’s gravitational binding energy and starts our spacecraft off with a reasonably large (on the order of a few km/s) velocity relative to the Earth’s motion around the Sun.On-board course corrections, where very small amounts of thrust accelerate the spacecraft to its optimal trajectory.And gravity assists, where we use the gravitational properties of other planets in orbit around the Sun to change our spacecraft’s velocity, either increasing or decreasing its speed with every encounter.It’s through the combination of these three actions that we can reach any location — if we’re patient and we plan properly — with only our current rocket technology.
    • John Lemke
       
      How we can do it now, if we plan right.
  • The initial launch is a very hard part right now. It takes a tremendous amount of resources to overcome the Earth’s gravitational pull, to accelerate a significant amount of mass to the Earth’s escape velocity, and to raise it all the way up through the Earth’s atmosphere.

  • The most optimal one for a one-way trip to Mars, for those of you wondering, that minimizes both flight time and the amount of energy needed, involves simply timing your launch right.
    • John Lemke
       
      The cheapest and the fastest. The one way ticket option.
  • When a planet orbits the Sun, there’s a lot of energy in that system, both gravitational energy and kinetic energy. When a third body interacts gravitationally as well, it can either gain some energy by stealing it from the Sun-planet system, or it can lose energy by giving it up to the Sun-planet system. The amount of energy performed by the spacecraft’s thrusters is often only 20% (or less) of the energy either gained-or-lost from the interaction!

Stealing Encryption Keys Just by Touching a Laptop - 0 views

  • A team of computer security experts at Tel Aviv University (Israel) has come up with a new potentially much simpler method that lets you steal data from computers — Just Touch it — literally.
  • In order to victimize any computer, all you need to do is wear a special digitizer wristband and touch the exposed part of the system. The wristband will measure all the tiny changes in the ground electrical potential that can reveal even stronger encryption keys, such as a 4,096-bit RSA key.
  • in some cases, you don't even have to touch the system directly with your bare hands. You can intercept encryption keys from attached network and video cables as well. Researchers called it a side-channel attack.
  • ...1 more annotation...
  • The actual attack can be performed quickly. According to the research, "despite the GHz-scale clock rate of the laptops and numerous noise sources, the full attacks require a few seconds of measurements using medium frequency signals (around 2 MHz), or one hour using low frequency signals (up to 40 kHz)."
