For-Profit College Scandal

The Big Money shines light on for-profit colleges that take federal money but use far more revenue for recruitment and marketing than for educating their students—a higher education crisis?

The Big Money shines light on for-profit colleges that take federal money but use far more revenue for recruitment and marketing than for educating their students—a higher education crisis? "As it stands now, for-profit schools are one of the economy’s embarrassments for believers in free markets. They have every incentive to skimp on the costs of education while collecting as much they can in tuition by encouraging students to max out their loans. Making them share the risks of those education loans makes them responsible for their failures. If you want for-profits to deliver a better profit, it’s the natural free-market approach."

How to make a black hole

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.

  • There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
  • CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
  • Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
  • Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
