...Exact details of which artists will be performing, however, remain fuzzy, with only legendary former Led Zeppelin guitarist Jimmy Page 100% confirmed. The list of invitees constitutes a roll call of the industry's biggest names: Beyoncé, Coldplay, Green Day, Kanye West, Lady Gaga and a host of lesser-known performers from Africa, Asia and the Americas. Garson is well-known in the industry - among other things, he has been executive producer of the Billboard Music Awards and the World Music Awards - and he appears confident the big names will show up. The all-day event is scheduled...
...classical computer trying to do an exact simulation of a complex process would just blow up,” White said...
Still, even these planetary finds are unlikely to be exact copies of Earth, and for a very simple reason. Kepler spots faraway planets by watching them transit, or pass in front of, their stars, blocking out a little bit of light and making the star slightly dimmer. The five planets just announced orbit very close to their suns, which is the reason they're so ridiculously hot. That proximity also means they move very fast, completing three or even more transits in the first round of observations - which is just the kind of data stream the Kepler team prefers...
...marks since at least the 1970s. But until the late '90s, epigenetic phenomena were regarded as a sideshow to the main event, DNA. To be sure, epigenetic marks were always understood to be important: after all, a cell in your brain and a cell in your kidney contain the exact same DNA, and scientists have long known that nascent cells can differentiate only when crucial epigenetic processes turn on or turn off the right genes in utero...
Through genetic analysis, the Science team was able to confirm that the tumors being spread from devil to devil were the same - genetically identical, exact clonal copies. Using genetic sequencing technology, the team also uncovered the tumors' transcriptome, which means the set of genes that are activated in tumors. Those activated genes best matched those of Schwann cells, which gave the team a clue as to where the disease originated - that's important because devils are unusually susceptible to a number of different cancers, and a quick diagnosis before the facial tumors get out of control would be helpful...
