More than 500 workers at Japan's, Keihin Electric Express Railway, must have their faces scanned each morning to determine their optimum smile. The "smile scan" analyzes a smile based on facial characteristics, from lip curves and eye movements to wrinkles. After the program scans you, it produces a smile rating that ranges from zero to 100 depending on the estimated potential of your biggest smile. If your number is sufficient, you can go about your day grinning like a maniac. If your smile number is too low the computer will give you a message such as, "lift up your mouth corners" or "you still look too serious." Every morning employees receive a printout of their daily smile which they are expected to keep with them throughout the day.

GrrlScientist writes "One of the most contentious issues among scientists who study the evolution of birds is identifying precisely when the modern birds (Neornithes) first appeared. This is due to conflicts between the fossil record and molecular dating methodologies. But there is another way to address this discrepancy. Because the evolution of parrots and cockatoos reflects the evolution of the birds (Aves) themselves, studying the psittaciformes offers compelling insights into this mystery. Further, because psittaciformes generally are not migratory and because they tend to occupy discrete ranges, their ancient patterns of diversification are easier to discern than for many other taxonomic orders of birds that have dispersed widely."

An anonymous reader writes "Rahul Sood, HP's CTO of gaming, argues that the days of a market that wants PCs running three $500 GPUs is history; he argues that it's really a tough or impossible sell. '... let's face it, high-end hardware has delivered diminishing returns in terms of value. This is why you don't see ridiculous offerings like Quad SLI and 2-kilowatt power supplies coming from our company.' But don't the ideas of customization and market pricing for components tend to undercut that? Is the gaming PC dead?"

merg717 writes "Six weeks ago, the Gonzo Scientist challenged researchers around the world to interpret their Ph.D. research in dance form, film the dance, and share it with the world on YouTube (Science, 10 October, p. 186). By the 11 p.m. deadline this past Sunday, 36 dances — including solo ballet and circus spectacle — had been submitted online." The vitamin D dance is particularly strange.

After the first announcement on 1997-04-27 and over eleven years of fresh start after fresh start, Duke Nukem Forever finally comes to your system. At least if your system is an Xbox 360. Jon Siegler, the webmaster of 3D Realms, confirms this on their site: "As has been reported around the net today, we can confirm that the game has indeed passed final certification with Microsoft on Friday the 15th of August (on our first try, no less). That means the game is done — it is now in the hands of Microsoft." Update: 08/19 10:47 GMT by T : Several readers have written with a correction: this announcement is actually about Duke Nukem 3D, rather than Duke Nukem Forever.
