Internet Opens Elite Colleges to All
Gilbert Strang is a quiet man with a rare talent: helping others understand linear algebra. He's written a half-dozen popular college textbooks, and for years a few hundred students at the elite Massachusetts Institute of Technology have been privileged to take his course.

Circumventing International Censorship
As Internet censorship continues in countries such as China and Burma, efforts to circumvent it are growing more sophisticated. Researchers at the Citizen Lab at the University of Toronto are adding new capabilities to one such project, called Psiphon, in hopes of expanding its reach in censored countries.

Intel's Ultrasmall Flash Hard Drive
The chip, also known as a solid-state hard drive, competes with similar chips from Samsung, which store data in gadgets such as Apple's iPod nano and iPhone. But the Intel chip comes with a standard electronics controller built in, which makes it easy and inexpensive to combine multiple chips into a single, higher-capacity hard drive.

'Retrospective rubber' remembers its old identities
The material, described in the journal Advanced Materials, forms a new class of shape-memory polymers, which are materials that can be stretched to a new shape and will stay in that form until heated, at which time they revert to their initial shape.

Does Your Vote Count? Only If it's Early
It really is the early bird that gets the worm, at least in politics. New research out of Brown University shows that the American political process through which we choose the President is "front loaded," with voters in the early primaries having much more clout than voters in later primaries.

Intel Looks Beyond Silicon
Intel has developed a new kind of transistor, made of a material other than silicon, that has the potential to be faster and use less electricity than today's chips. And, crucially, the new transistors are economical and could be fabricated using existing manufacturing facilities because they can be built directly on top of standard silicon wafers.
