Policing "The Police"
Anticipating a report to be released in May criticizing the music industry for its carbon footprint, industry leaders have met in London to discuss reducing the environmental impact of big tours like The Police and U2.
Anticipating a report to be released in May criticizing the music industry for its carbon footprint, industry leaders have met in London to discuss reducing the environmental impact of big tours like The Police and U2. "Imagine U2 clambering on to a train to take them to a sold-out stadium; Keith Richards swigging from a bottle of organic, Fairtrade booze while Bon Jovi recycle their post-gig waste. Unlikely as it sounds, it may yet come to pass as rock'n'roll's tradition of painting the town red fades to an ethical shade of green. Polluting private jets, excessive dressing room demands and arena-busting tours are no long sustainable, according to the biggest study so far on the effect of the live music industry on our environment. In recent years, musicians such as U2, Kasabian and Madonna have been criticised for the size of their carbon footprint due to the huge scale of their tours. Notwithstanding Sting's personal enviro-activism, his group, the Police, was recently condemned as "the dirtiest band in the world" in an NME survey, because of the size and length of their 2007 reunion tour. The report, which will be published in May, is the first to map the carbon footprint of live music – from platinum-selling rock stars and orchestras to theatre groups and pub bands. Although it doesn't name and shame, it does blame performers for releasing about 540,000 tonnes of greenhouse gases every year."
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.
