Ultra-Sensitive Camera To Measure Exoplanet Sizes 62

Posted by timothy on Saturday December 13, 2008 @03:30PM from the ignoring-global-poverty dept.

Roland Piquepaille writes "US astronomers and engineers have built a new camera to precisely measure the size of planets moving around distant stars. This camera has been dubbed OPTIC — short for 'Orthogonal Parallel Transfer Imaging Camera.' According to the research team, it is 'so sensitive that it could detect the passage of a moth in front of a lit window from a distance of 1,000 miles.' I'm not sure if this analogy is right, but the team said it was able to precisely define the size of a planet called WASP-10b which is orbiting around the star WASP-10, about 300 light-years from Earth."

Evolution of Mona Lisa Via Genetic Programming 326

mhelander writes "In his weblog Roger Alsing describes how he used genetic programming to arrive at a remarkably good approximation of Mona Lisa using only 50 semi-transparent polygons. His blog entry includes a set of pictures that let you see how 'Poly Lisa' evolved over roughly a million generations. Both beautiful to look at and a striking way to get a feel for the power of evolutionary algorithms."

It's significantly easier to hide a malicious backdoor inside a huge software project than a small one. Linux has already had a near miss back in 2003, when the CVS repository was compromised. Considering how many mission-critical applications run under Linux, there's a huge financial incentive to hide a backdoor somewhere in those 10 million lines.

Repairing Genetic Mutations With Lasers? 65

Roland Piquepaille writes "German researchers at the Christian-Albrechts-Universität zu Kiel (CAU) think they've proved that genetic information can be controlled by light. The group studied the interaction between the four DNA bases — adenine (A), cytosine (C), guanine (G), and thymine (T) — by using femtosecond time-resolved fluorescence spectroscopy. The researchers think that they've demonstrated that DNA strands differ in their light sensitivity depending on their base sequences. The team thinks that it might be possible in the future to repair gene mutations using laser radiation. One of the project leaders said that 'it might even be possible under some circumstances to make transistors from DNA that would work through the hydrogen bonds.' It's not the first time I've heard about DNA computing, but this new approach looks promising."

Elcomsoft Claims WPA/WPA2 Cracking Breakthrough 349

secmartin writes "Russian security firm Elcomsoft has released software that uses Nvidia GPUs to speed up the cracking of WPA and WPA2 keys by a factor of 100. Since the software allows them to network thousands of PCs, this anouncement effectively signals the death of wireless networking in business networks; any network handling sensitive data should start using VPN encryption on machines connecting over Wi-Fi networks, or stop using these networks altogether."

sterlingda writes: "Toshiba has developed a new class of nuclear reactor 100 times smaller than a standard reactor. These micro sized nuclear reactors could be used to power large houses, apartment blocks or some city blocks. The new 200 kilowatt reactor, which is only 20 feet by 6 feet is engineered to be fail-safe and totally automatic and will not overheat. The new micro reactor uses no control rods to initiate the reaction, but uses reservoirs of liquid lithium-6, an isotope that is effective at absorbing neutrons. The whole whole process is self sustaining and can last for up to 40 years, producing electricity for only 5 cents per kilowatt hour, about half the cost of grid energy. Toshiba expects to install the first reactor in Japan in 2008 and to begin marketing the new system in Europe and America in 2009."
