Dolphins See While Blindfolded
A study has found that blindfolded dolphins can pick up on the actions of other dolphins, even imitating their actions.
A study has found that blindfolded dolphins can pick up on the actions of other dolphins, for instance imitating their actions. Whether through echolocation, sonar or other means is still unclear. Dr. Kelly Jaakkola, director of the nonprofit marine mammal research center, said the research to better understand dolphin intelligence will surely help further their conservation. She said such study may also be helpful in better grasping the complexities of human intelligence. "It's human nature to care more about animals we perceive as intelligent. So the more we can showcase that intelligence we give people a way to connect, to care and therefore conserve."
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.
