Sega announced yesterday that it plans to bring back a number of popular Dreamcast games, updating them and releasing them for download on the PlayStation Network and Xbox Live. Sonic Adventure and Crazy Taxi will come first, with further announcements expected after E3. "Both of the games will be based on the Dreamcast originals, but will be updated with high-definition graphics, surround sound, online leaderboards, and Achievement and Trophy support." Kotaku has a list of other titles they hope to see — what game(s) would you like Sega to bring back?

Al writes "Researchers at Microsoft and the University of California, San Diego have developed a network adapter that lets a computer enter sleep mode without disrupting the network connection. The adapter, dubbed Somniloquy (meaning to talk in one's sleep), consists of a gumstix running embedded Linux, 64MB of RAM and a 2G SD memory card, connected via USB. The adapter keeps the network connection going and the researchers have also developed a simplified IM client and bittorrent client that carry out more complicated tasks autonomously, only waking the computer if, for example, an actualy IM is received or a download is completed."

A new study has shown that even sperm can be superficial. Researchers found that males of many animal species, including humans, can adjust the speed and effectiveness of their sperm by regulating the amount of seminal fluid they produce during copulation. The determining factor on that amount of fluid seems to be whether the male finds the female attractive.
