Sorry, should have re-read first. It was only ~37000 galaxies.

http://adsabs.harvard.edu/abs/2008MNRAS.388.1686L They measured the spin of a few 100000 galaxies in both hemispheres. At first they found the _same_ preferred spin in any direction, then they started mirroring half of the galaxies before showing them to people and the effect vanished. They found no dipole.

Quake 3 For Android 137

An anonymous reader writes "Over the last two months I ported Quake 3 to Android as a hobby project. It only took a few days to get the game working. More time was spent on tweaking the game experience. Right now the game runs at 25fps on a Motorola Milestone/Droid. 'Normally when you compile C/C++ code using the Android NDK, the compiler targets a generic ARMv5 CPU which uses software floating-point. Without any optimizations and audio Quake 3 runs at 22fps. Since Quake 3 uses a lot of floating-point calculations, I tried a better C-compiler (GCC 4.4.0 from Android GIT) which supports modern CPUs and Neon SIMD instructions. Quake 3 optimized for Cortex-A8 with Neon is about 15% faster without audio and 35% with audio compared to the generic ARMv5 build. Most likely the performance improvement compared to the ARMv5 build is not that big because the system libraries of the Milestone have been compiled with FPU support, so sin/cos/log/.. take advantage of the FPU.''

Google Hacked, May Pull Out of China 687

D H NG writes "Following a sophisticated attack on Google infrastructure originating from China late last year, Google has decided to take 'a new approach' to China. In their investigation, Google found that more than 20 large companies had been infiltrated and dozens of Chinese human rights activists' Gmail accounts had been compromised. Google has decided to 'review the feasibility of [its] business operations in China,' no longer censoring results in Google.cn, and if necessary, to 'shut down Google.cn, and potentially [Google's] offices in China.'"
