Whether they annoy you or fulfill your nerdy collection habit, achievements have spread across the gaming landscape and are here to stay. The Xbox Engineering blog recently posted a glimpse into the creation of the Xbox 360 achievement system, discussing how achievements work at a software level, and even showing a brief snippet of code. They also mention some of the decisions they struggled with while creating them: "We are proud of the consistency you find across all games. You have one friends list, every game supports voice chat, etc. But we also like to give game designers room to come up with new and interesting ways to entertain. That trade-off was at the heart of the original decision we made to not give any indication that a new achievement had been awarded. Some people argued that gamers wouldn't want toast popping up in the heat of battle and that game designers would want to use their own visual style to present achievements. Others argued for consistency and for reducing the work required of game developers. In the end we added the notification popup and its happy beep, which turned out to be the right decision, but for a long time it was anything but obvious."

Created by Lauren Theis and Lila Kerr, the ingenious DIY centrifuge is cobbled together using a salad spinner, some plastic lids, combs, yogurt containers, and a hot glue gun. The simple and easily-replicated design could be an invaluable tool for clinics in the developing world, enabling them to separate blood to detect diseases like anemia without electricity."

Stoobalou writes with this excerpt from Thinq.co.uk: "A new study has shown that brain training games do little to exercise the grey matter. Millions of people who have been prodding away at their Nintendo DS portable consoles, smug in the knowledge that they are giving their brains a proper work-out, might have to rethink how they are going to stop the contents of their skulls turning into mush."

From the article: 'Today proud Mr Smith said: "The midwife had checked Emma earlier in the day but contractions started up again at about 8pm so we called the midwife to come back. But then everything happened so quickly I realized Emma was going to give birth. I wasn't sure what I was going to do so I just looked up the instructions on the internet using my BlackBerry."'"
