'Super-fans' are most irked by queue-jumpers. People were equally peeved whether someone cut in front or behind, and cutters who jumped beside a friend were less likely to attract scorn."

Khemisty writes "Back in grade school you were probably taught the importance of warm-up exercises, and it's likely you've continued with pretty much the same routine ever since. Science, however, has moved on. Researchers now believe that some of the more entrenched elements of many athletes' warm-up regimens are not only a waste of time but are actually bad for you. The old presumption that holding a stretch for 20 to 30 seconds — known as static stretching — primes muscles for a workout is dead wrong. It actually weakens them. In a recent study conducted at the University of Nevada, athletes generated less force from their leg muscles after static stretching than they did after not stretching at all. Other studies have found that this stretching decreases muscle strength by as much as 30 percent. Also, stretching one leg's muscles can reduce strength in the other leg as well, probably because the central nervous system rebels against the movements."

CheshireCatCO writes "The first pictures from yesterday's flyby of Enceladus are now public. At closest approach, Cassini was set spinning to cancel out the apparent motion of Enceladus so as to capture unsmeared images during the 40,000-mph flyby. Although it wasn't clear that this would work (errors in pointing could easily have made the cameras miss their targets), the maneuver panned out beautifully, producing spectacular images of the surface. Images show the 'tiger stripes' at the south pole, including at least one location that has been identified as a source of a jet, as well as considerable vertical relief, easily visible thanks to the low sun-angle near the south pole at present. Processed, enhanced images should follow shortly."

Spuddly writes with links to Daniel Philips and his work on the Ramback patch, and an analysis of it by Jonathan Corbet up on LWN. The experimental new design for Linux's virtual memory system would turn a large amount of system RAM into a fast RAM disk with automatic sync to magnetic media. We haven't yet reached a point where systems, even high-end boxes, come with a terabyte of installed memory, but perhaps it's not too soon to start thinking about how to handle that much memory.

miowpurr writes "A new X-Prize for ultra fuel efficient cars has been announced. The winning car must 'carry four or more passengers and have climate control, an audio system and 10 cubic feet of cargo space. They also must have four or more wheels, hit 60 miles per hour in less than 12 seconds and have a minimum top speed of 100 miles per hour and a range of 200 miles. Those that qualify will race their vehicles in cross-country races in 2009 and 2010 that will combine speed, distance, urban driving and overall performance.'"

Stony Stevenson writes "Researchers in the US have developed a microchip fan with no moving parts that operates silently and generates enough wind to cool a laptop computer. The solid-state fan, developed with support from the US National Science Foundation (NSF), is touted as the most powerful and energy efficient fan of its size. The device produces three times the flow rate of a typical small mechanical fan and is one-fourth the size. The technology has the power to cool a 25W chip with a device smaller than one cubic-cm and can someday be integrated into silicon to make self-cooling chips, according to the researchers."
