jedrick conner writes: Hewlett-Packard's microneedle technology is used in Hewlett-Packard's patented process for its inkjet cartridges, could soon be used in transdermal patches to deliver time-controlled release of drugs to patients. Still at the prototype stage, the patch will likely be 25 mm square in size and 3 mm thick. It will incorporate an array of microneedles that are between 75 and 100 microns, which will penetrate the top dry layer of the skin, also known as the stratum corneum. Above the microneedles is an array of wells, [and] those wells can hold one or a number of drugs, adding that for the actuation of drugs, the device has "an active mechanism to push the drug through the needle".

Submission + - Most Powerful Star Explosion Observed

necro81 writes: The NY Times is reporting a discovery from a team of researchers about observations of the cataclysmic explosion of a 100- to 200-solar-mass star — the brightest stellar explosion ever observed. The researchers believe that the explosion is similar to the death spasms of the first stars in the universe. Rather than create a black hole, the super-massive star's collapse is believed to have been so energetic as to create unstable electron-positron pairs that tore the star apart before it could collapse into a black hole — seeding the universe with heavier elements.

There's another way to do it. Put him to bed ten minutes earlier every day during the week leading up to the change (or later, depending on which one it is). Then, their system has a chance to get gradually accustomed to the change.
