To Russia Without Love
Russia is threatening stop American families from adopting Russian orphans after a Tennessee family sent its adopted Russian son back to Moscow unaccompanied, save for a written letter.
Russia is threatening stop American families from adopting Russian orphans after a Tennessee family sent its adopted Russian son back to Moscow unaccompanied, save for a written letter. "Russia threatened to suspend all child adoptions by U.S. families Friday after a 7-year-old boy adopted by a woman from Tennessee was sent alone on a one-way flight back to Moscow with a note saying he was violent and had severe psychological problems. The boy, Artyom Savelyev, was put on a plane by his adopted grandmother, Nancy Hansen of Shelbyville. 'He drew a picture of our house burning down and he'll tell anybody that he's going to burn our house down with us in it,' she told The Associated Press in a telephone interview. 'It got to be where you feared for your safety. It was terrible.'" Russian Foreign Minister Sergey Lavrov called the actions by the grandmother 'the last straw' in a string of U.S. adoptions gone wrong, including three in which Russian children had died in the U.S."
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.
