Small Cars Are a Big Trend
Environmental friendliness is an added bonus for consumers looking to save money by purchasing cars with smaller engines. American car companies are looking to Europe, says Wired.
Environmental friendliness is an added bonus for consumers looking to save money by purchasing cars with smaller engines. American car companies are looking to Europe, says Wired. "'People used to think that small meant you were sacrificing something,' says Ford’s Sheryl Connelly, who has the cool title of global trends and futuring manager. 'Vast improvements in technology have shifted that paradigm. In a lot of ways, small has become chic.'...Beyond providing consumers with the performance they expect — and the numbers Ford needs to meet tightening fuel economy regulations — Ford says the engines are more cost-effective."
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.
Protected animals are feared to be headed for the black market.
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.
- 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.
