Using Social Media the Right Way
Martin Belam's account of the BBC's Social Media Summit, including hostile questions over Al Jazeera's role in the Arab spring uprisings and why the NYT has social media right.
What's the Latest Development?
The BBC's recent Social Media Summit has many talking, including Martin Belam, who blogs on some of the more interesting aspects. These include social media research showing that whilst time spent on news sites is staying relatively static, that spent on social media destinations is rapidly increasing. He was also impressed by Al Jazeera's Esra Dogramaci, in her response to "hostile questioning" over the station’s role in the Arab spring uprisings.
What's the Big Idea?
Belam was also interested in Liz Heron's take on social media use by the New York Times. "She also made the excellent point that journalists seem to have found a natural home on Twitter, which makes it easy sometimes for our social media strategies to ignore the much bigger potential reach and wider engagement on Facebook."
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.
