The biggest addition in this release is click-to-play plugins, announced back in October. In short, the addition means Mozilla will now prompt Firefox users on Windows with old versions of Adobe Reader, Adobe Flash, and Microsoft Silverlight (more will be added eventually)." The release notes are available, as is a list of changes for devs. Firefox for Android got a new release as well (notes).

zootropole alerts us to a press release issued today by Lawrence Livermore National Laboratory, announcing the production of 'billions of particles of anti-matter.' "Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma 'jet.' This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and gamma ray bursts." The press release doesn't characterize the laser used in this experiment, but it may have been this one.

An anonymous reader writes "Developer 2D Boy has written that they are seeing an 82% piracy rate for everyone's favorite DRM-free physics puzzler, World of Goo . Surprisingly, this rate is in-line with what they were expecting. The article also features a fascinating comparison with the piracy rate of another game that was shipped complete with DRM, at 92%. There seemed to be no major difference in the outcomes of the rate regardless of whether DRM was used or not ... well, no difference other than the cost to implement such nonsense."
