I work professionally as a software developer with Linux, but the Windows installs at my workplace are quite limited, so my current/working knowledge of Windows is almost nil. At home we have all been happy with this arrangement, and the kids have been using their Nintendos, PS2/3's and mobile phones up until now. However, my oldest kid (12) now wants to play World of Warcraft and League of Legends with his friends. I have spent more hours than I like to admit getting this to work with Wine, with limited success — seems to always fail at the last moment. I considered an Apple machine, but they seem to be quite expensive.
So, I am going to bite the bullet, and install Windows 7 on a spare Lenovo T400 laptop, which I estimate will be able to run both Windows 7 and the games in question."

writes "A beam of electrons can pick up and carry nanoparticles, according to a new study (abstract). The so-called electronic tweezers could help scientists in diverse tasks, such as building up new materials nanoparticle-by-nanoparticle, and measuring the forces between nanoparticles and living cells, the researchers say. In the past, scientists have manipulated microsized particles, including single cells, using a beam of laser light called optical tweezers. But the force required to trap a particle with optical tweezers increases as the particle gets smaller, making grappling with nanoparticles difficult. Researchers at Lawrence Berkeley National Laboratory developed an alternative to optical tweezers by modifying a transmission electron microscope, which produces images by passing a stream of electrons through a sample."
