38% of Downloaders Paid For Radiohead Album 562

brajesh sends us to Comscore for a followup on the earlier discussion of Radiohead making $6-$10 million on their name-your-own-cost album "In Rainbows" — with the average price paid being between $5 and $8. Comscore analyzes the numbers: "During the first 29 days of October, 1.2 million people worldwide visited the 'In Rainbows' site, with a significant percentage of visitors ultimately downloading the album. The study showed that 38 percent of global downloaders of the album willingly paid to do so, with the remaining 62 percent choosing to pay nothing... Of those who were willing to pay, the largest percentage (17 percent) paid less than $4. However, a significant percentage (12 percent) were willing to pay between $8-$12, or approximately the cost to download a typical album via iTunes, and these consumers accounted for more than half (52 percent) of all sales in dollars."

Submission + - Optical Tweezers pick up cells

RealGene writes: MIT assistant professor Matthew Lang and graduate student David Appleyard have developed optical tweezers
that allow them to move, control and measure objects placed on a silicon chip.
As a demonstration of the system's versatility, they set it up to collect and hold 16 tiny living
E. coli cells at once on a microchip, forming them into the letters MIT.

Submission + - MIT's mini tractor beam

An anonymous reader writes: MIT scientists have developed a way to use light to grab and move minuscule particles on a microchip. The research could lead to fine-grained biological sensors and other precisely built nanoscale devices. Optical tweezers have been used on transparent media — like a microscope slide — that let the light shine through and hold objects in a tractor beam-like embrace. (This is possible because light's individual photons transfer minuscule amounts of force to particles they hit.) What's new in the optical tweezer from MIT's Matt Lang and David Appleyard is the use of infrared light. Unlike visible light, the infrared does not bounce off the silicon used as the basis for microchips. That means that MIT's optical tweezer can be used not just for study but to build structures on the surface of chips. Lang and Appleyard proved their technique by getting 16 live E. coli cells to spell out "MIT" on a chip.
