New Nanotech Fabric Never Gets Wet 231

holy_calamity writes "New Scientist reports on a simple coating for polyester that renders it unwettable — even after two months underwater it emerges dry to the touch. Water cannot attach to the new fabric thanks to nanostructured filaments and a structure that traps a constant air layer. One potential use is for low-drag swim wear."

IBM's Teri-is-a-Girl-and-Terry-is-a-Boy Patent 277

theodp writes "The USPTO has granted IBM a patent for utilizing naming conventions to assign gender-based avatars for instant messaging. A user named Teri, IBM explains, would be given a girl avatar, while a user named Terry would be provided with a boy avatar. The three IBM 'inventors' were stymied by users named Pat, who as a result will be assigned a 'generic, genderless human figure image as his or her avatar.' Way to honor that significant-technical-content patent pledge, Big Blue!"

Fuel Efficiency and Slow Driving? 1114

vile8 writes "With the high gas prices and ongoing gas gouging in my hometown many people are trying to find a reasonable way to save gas. One of the things I've noticed is people driving exceptionally slow, 30mph in 45mph zones, etc. So I had to take a quick look and find out if driving slow is helpful in getting better mileage. I know horsepower increases substantially with wind resistance, but with charts like this one from truckandbarter.com it appears mileage is actually about the same between 27mph and 58mph or so. So I'm curious what all the drivers out there with the cool efficiency computers are getting ... of specific interest would be the hemis with MDS; how do those do with the cylinder shutoff mode at different speeds?" Related: are there any practical hypermiling techniques that you've found for people not ready to purchase a new car, nor give up driving generally?
