Operation Socialist: How GCHQ Spies Hacked Belgium's Largest Telco - 4 views

  •  
    interesting story with many juicy details on how they proceed ... (similarly interesting nickname for the "operation" chosen by our british friends) "The spies used the IP addresses they had associated with the engineers as search terms to sift through their surveillance troves, and were quickly able to find what they needed to confirm the employees' identities and target them individually with malware. The confirmation came in the form of Google, Yahoo, and LinkedIn "cookies," tiny unique files that are automatically placed on computers to identify and sometimes track people browsing the Internet, often for advertising purposes. GCHQ maintains a huge repository named MUTANT BROTH that stores billions of these intercepted cookies, which it uses to correlate with IP addresses to determine the identity of a person. GCHQ refers to cookies internally as "target detection identifiers." Top-secret GCHQ documents name three male Belgacom engineers who were identified as targets to attack. The Intercept has confirmed the identities of the men, and contacted each of them prior to the publication of this story; all three declined comment and requested that their identities not be disclosed. GCHQ monitored the browsing habits of the engineers, and geared up to enter the most important and sensitive phase of the secret operation. The agency planned to perform a so-called "Quantum Insert" attack, which involves redirecting people targeted for surveillance to a malicious website that infects their computers with malware at a lightning pace. In this case, the documents indicate that GCHQ set up a malicious page that looked like LinkedIn to trick the Belgacom engineers. (The NSA also uses Quantum Inserts to target people, as The Intercept has previously reported.) A GCHQ document reviewing operations conducted between January and March 2011 noted that the hack on Belgacom was successful, and stated that the agency had obtained access to the company's

    I knew I wasn't using TOR often enough...
  •  
    Cool! It seems that after all it is best to restrict employees' internet access only to work-critical areas... @Paul TOR works on network level, so it would not help here much as cookies (application level) were exploited.

Electron spins controlled using sound waves - 0 views

  •  
    Cornell applied physicists have demonstrated an unprecedented method of control over electron spins using extremely high-frequency sound waves - new insights in the study of the spin of the electron. Crazy idea but, no further need for complicated quantum encryption techniques of sound signals?

Quantum entanglement at ambient conditions in a macroscopic solid-state spin ensemble - 1 views

  •  
    Quoted from one of the authors in a separate interview: "We know that the spin states of atomic nuclei associated with semiconductor defects have excellent quantum properties at room temperature," said Awschalom, Liew Family Professor in Molecular Engineering and a senior scientist at Argonne National Laboratory. "They are coherent, long-lived and controllable with photonics and electronics. Given these quantum 'pieces,' creating entangled quantum states seemed like an attainable goal." Bringing the quantum world to the macroscopic scale could see some interesting applications in sensors, or generally entanglement-enhanced applications.
  •  
    They were previously working on the same concept in N-V centers in diamond (as a semiconductor). Here the advantage is that SiC could in principle be integrated with Si or Ge. Anyway its all about controlling coherence. In the next 10 years some breakthroughs are expected in the field of semiconductor spintronics, but quantum computing in this way lies still in the horizon

Nature Today | First tomatoes and peas harvested on Mars and moon soil simulant - 2 views

  •  
    Researchers from Alterra Wageningen UR were able to grow and harvest ten different crop species on Mars and moon simulant. 'The total above ground biomass produced on the Mars soil simulant was not significantly different from the potting compost we used as a control' researcher Wieger Wamelink said. I wonder if the taste was as disappointing as that of normal dutch veggies :P

Wearable Robot Transforms Musicians into Three-Armed Drummers - 2 views

  •  
    Now this would be really cool if it had a brain computer interface and could be controlled by a trained drummer's mind! Science and Technology Society and Culture Georgia Institute of Technology researchers have built a wearable robotic limb that allows drummers to play with three arms. The two-foot long "smart arm" can be attached to a musician's shoulder. It responds to human gestures and the music it hears.

    Strong evidence for d-electron spin transport at room temperature

    WOW! Great non-local signals, at room temperature!!! Spin transistor on the way finally!? (of course electric field gate controlled is fundamental) See more about the "quest" for the spin transistor here: http://spectrum.ieee.org/semiconductors/processors/the-quest-for-the-spin-transistor

"Space cops" may help avoid collisions of satellites and space debris - 0 views

  •  
    U.S. scientists say they're working on mini-satellites that could function as "space cops" to help avoid collisions in space of satellites and space debris. Researchers at the Lawrence Livermore National Laboratory in California have tested a ground-based satellite to prove it is possible to refine the orbit of another satellite in low Earth orbit.

The World's Largest Solar Plant Started Creating Electricity Today - 3 views

    The enormous solar plant-jointly owned by NRG Energy, BrightSource Energy and Google-opened for business today ... well yesterday, but still impressive!

    impressive! and google is among the owners.
  •  
    impressive pictures - looking at the 2nd to last and 4th to last one, I am wondering how this distributed individually control of the mirrors works - and idea?
  •  
    Machine learning obviously. Most likely neural networks :P On the other hand: http://sploid.gizmodo.com/the-worlds-largest-solar-plant-is-killing-birds-meltin-1525107821

Autonomous drones flock like birds (video) #Nature - 2 views

  •  
    A Hungarian team has created the first drones that can fly as a coordinated flock. The researchers watched as the ten autonomous robots took to the air in a field outside Budapest, zipping through the open sky, flying in formation or even following a leader, all without any central control.
  •  
    old news, but wow .... Nature is becoming more and more like a magazine and less and less a scientific journal. This stuff is highly irrelevant but to the group that did it.
  •  
    this is not a nature paper but just an article on their website - the papers they provide as references are all old

Mars Code | Communications of the ACM - 1 views

  • As can be expected, all functions on the rover, and on the spacecraft that brought it to its destination 350 million miles from Earth, are controlled by software. This article discusses some of the precautions the JPL flight software team took to improve its reliability.

    Interesting read if you're interested on the kind of coding that goes into something like the Curiosity rover. :) btw.. nice fill-packet being sent by Curiosity: "Elvis has Spirit. The answer is 42....END\r\n"
