How to Beat Bullies
Much of the accepted wisdom on bullying is not only ineffective, it makes things worse. Advice to "just be nice", "don't be a tattletale" and "'just ignore them'" needs revisiting.
Much of the accepted wisdom on bullying is not only ineffective, it makes things worse. Advice to "just be nice", "don't be a tattletale" and "'just ignore them'" needs revisiting. "Bullying: It's been called a national epidemic and it's getting worse. It has been the focus of considerable attention lately as America looks at its widespread, even fatal, impact on youth. But more than media outcry, we need practical tools to combat bullying, empower children, and protect victims." "If we empower our children to stand up for themselves...they're less likely to be victims and more likely to maintain a balance of power."
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.
