Once upon a time, you could crack open a radio, a telephone, a lawnmower, even a car, take it apart and figure out how it worked. No more. Pretty much everything we use these days comes with computer chips, which you can't really take apart. (I mean, you can, but all you'll find inside are a bunch of 1's and 0's with no obvious logic.) So car mechanics can snap a new chip into an engine, wait till it whirs and watch the gears come to life, but do they know what's going on in there? For most of us, chips are "black boxes." They work, but we don't know why.

The latest results, from 2012, show that U.S. students ranked below average in math among the world's most-developed countries. They were close to average in science and reading.

Commemorating the 25th World AIDS Day a day late, President Obama announced an initiative Monday to find a cure for HIV infections that would be funded by $100 million shifted from existing spending.
"The United States should be at the forefront of new discoveries into how to put people into long-term remission without requiring lifelong therapies — or better yet, eliminate it completely," Obama said at a meeting in the Eisenhower Executive Office Building next to the White House.
