Submission The first image taken with an ultra low field MRI->

KentuckyFC writes: "MRI machines are about to get smaller, much smaller. Most of their bulk is taken up by the huge superconducting magnets required to generate fields of about a Tesla. Now a team at the Los Alamos National Lab in New Mexico has built a machine that can produce images using a field of only a few microTesla. So giant superconducting magnets aren't necessary, a development that has the potential to make MRI machines much smaller, perhaps even suitcase sized. Today, the team has posted sections of the first 3D brain image taken with the device (abstract, pdf)."

Submission MIT researchers develop color changing gel 1

An anonymous reader writes: The researchers at MIT have created a new structured gel that can rapidly change color in response to a variety of stimuli, including temperature, pressure, salt concentration and humidity. Apparently the structured gel can be used as a fast and inexpensive chemical sensor, says Edwin Thomas, a professor of materials Science and engineering at MIT. The gel will be most useful in a food processing plant, where the sensor will be able to indicate whether food that must remain dry has been overly exposed to humidity.

Submission Vista vs. the Gibbon 4

ricegf writes: If you had 7 computers running various versions of Windows and Linux, on which machine would you choose to do most of your work? Rupert Goodwins describes his experience thus: 'So here's the funny thing. I've used Windows since 1.0. I've lived through the bad times of Windows/386 and ME, and the good times of NT 3.51 and 2K. I know XP if not backwards, then with a degree of familiarity that only middle-aged co-dependents can afford each other. Then how come I'm so much more at home with Ubuntu than Vista?'

If it has syntax, it isn't user friendly.
