  • quantum cryptography, according to some engineers, is not without its faults. In a preprint submitted late last week to arXiv, Hoi-Kwong Lo and colleagues at the University of Toronto, Canada, claim to have hacked into a commercial quantum cryptography system by exploiting a certain practical “loophole”.

  • For 15 years, J. Craig Venter has chased a dream: to build a genome from scratch and use it to make synthetic life. Now, he and his team at the J. Craig Venter Institute (JCVI) in Rockville, Maryland, and San Diego, California, say they have realized that dream.
  • "One thing is sure," Boeke says. "Interesting creatures will be bubbling out of the Venter Institute's labs."

    wow, a big step in genomics...!
  • Ma Ru on 21 May 10
     
    But isn't it just yet another word abuse? From what I understand, they just synthesised a genome identical to the one of an existing bacteria... while undoubtedly nice work, this is *very* far from "creating life from scratch"... The fact that you are able to copy something, doesn't mean you understand how it works...
  • pacome delva on 27 May 10
     
    well of course we are far from engineering specific functions, and this is just a copy of a function that already existed. However it is quite impressive and the first time it is done. And the challenge here is not really to "copy" the ADN, but the fact that it works... in other words it is not because you copy the ADN identically that the phenotype (traduction of the ADN) will be the same, which is the case in this experiment.

  • First there were atomic clocks that beat at microwave frequencies. Then along came optical clocks that provide higher frequency standards. Now, physicists in the US have unveiled plans to build the first “nuclear clock” that runs at still higher frequencies. And because it is based on a solid material, the team claims that such a frequency standard could be far less complicated than gas-based atomic and optical clocks – while delivering the same or better accuracy.

    I guess it is a symbolic way of flying the space shuttle for the last time! as JAXA does it with your name - if you want to - for all their scientific missions. Nice initiative indeed!
  • Ma Ru on 09 Jun 10
     
    Wow, they even mentioned it in the news on the Polish radio yesterday... What I am curious is if they really take the physical (or at least digital) photo and name to the orbit, or is this just, as you called it, "symbolic" ...

    It is usually for real. Sometimes it is on a plate or slab, sometimes on a DVD, ... I will have my name on STS-134 :-)

    How you know you have been to long in xy. The Finnish version. My favorite is 33. You accept that 80°C in a sauna is chilly, but 20°C outside is freaking hot. Quite a lot of them are outdated, esp. about opening hours of shops, and one is definitely missing. Your normal mealtime has shifted to 11am for lunch and 5pm for dinner. But don't worry, it's a really comfy place here, isnt' it Jose??

    well somethings you get used to in a year (like salmiakki or koskenkorva) others don't (seriously, lunch at 11?!?!)
  • Ma Ru on 23 Jun 10
     
    But what stage are you in already, Luzi?
  • Luzi Bergamin on 24 Jun 10
     
    I would say a 50% Finn. I do have lunch at 11am, every working day, an 80 degrees sauna indeed is just a warm room. But I will never get used to salmiakki (which is just literally eating a cleaning agent!!) and you can imagine that "silence is fun" is not really MY motto...
  • LeopoldS on 24 Jun 10
     
    True?? 22. You understand why the Finnish language has no future tense. No, I don't think I ever will understand that one... Finns are quite future-oriented at two particular times of the year. On the day after Midsummer (see above), they say "Well, it's all downhill from now on" and prepare feverishly for winter, and similarly after December 21st they perk up and start thinking about Midsummer - ignoring the fact that they still have to get through January, February and March before the place becomes inhabitable again...

    ... Finnish language has no future tense. That's true

    everything expressed with "tomorrow I go to " or "in one year" etc? what about the distinction between to future events, one conditional on the other?

  • A new technique might soon enable cosmologists to map the universe even when they can't pick out individual galaxies. If it works, researchers would be able to probe the structure of 500 times as much of the universe as they have studied so far.
  • With a purpose-built radio telescope, the approach could map as much as 50% of the observable universe far faster and cheaper than galaxy surveys can, Loeb says.

    Also, this reminds me of a poem that once sprung out on my Linux console login: The wombat lives across the seas, Among the far Antipodes. He may exist on nuts and berries, Or then again, on missionaries; His distant habitat precludes Conclusive knowledge of his moods, But I would not engage the wombat In any form of mortal combat.

  • However, should one spacecraft in such a swarm begin to fail and risk a calamitous collision with another, it must sense its end is nigh and put itself on a course that takes it forever away from the swarm – for the greater good of the collective.
