...even when researchers uncover a new piece of data, it isn't always clear what it means. That's very much the case with a new paper about methane emissions, published Thursday in Science. Based on a series of expeditions to the margins of the Arctic Ocean by ship and helicopter, University of Alaska researcher Natalia Shakhova and her colleagues report that methane, a greenhouse gas that is 30 times more effective in trapping heat in the atmosphere than carbon dioxide, is bubbling up from the continental shelf and leaking into the atmosphere. The estimated total: 8 teragrams - that...
...Titanic enjoyed a whopping 48.3% edge; on the Lusitania it was a smaller but still significant 10.4%. The most striking survival disparity - no surprise, given the era - was determined by class. The Titanic's first-class passengers had a 43.9% greater chance of making it off the ship and into a lifeboat than the reference group; the Lusitania's, remarkably, were 11.5% less likely.

...grinding of an iceberg - would also be likelier to spark panic. Finally, there was the simple fact that everyone aboard the Lusitania was aware of what had happened to the Titanic just three years earlier and thus disabused of the idea that there was any such thing as a ship that was too grand to sink - their own included...
...fact that the two vessels did sink is an unalterable fact of history, and while ship design and safety protocols have changed, the powder-keg nature of human behavior is the same as it ever was. The more scientists learn about how it played out in disasters of the past, the more they can help us minimize loss in the future...
...Steve Irwin was later joined by two more vessels from the Sea Shepherd's fleet: The high-tech stealth boat Ady Gil, which sunk in the Southern Sea following a collision with whaling boat on Jan. 6., and the Bob Barker, a ship that survived a collision on Feb. 6 and is currently exchanging rancid-butter bombs with water canon fire from the whalers. On Feb. 15, New Zealander Pete Bethune, the former captain of the Ady Gil crew, boarded Japan's Shonan Maru 2 in the middle of the night, presented the skipper with a $3 million invoice...
