...around distant stars in the mid-1990s, they were baffled. Many of these early discoveries involved worlds as big as Jupiter or even bigger - but they orbited their stars so tightly that their "years" were just days long. Nobody could imagine how a Jupiter or anything like it could form in such a hostile location, where the radiation of the parent star would have pushed the light gas - which makes up most of such a planet's mass - out to the farthest reaches of the solar system before it could ever coalesce. (See the top 10 scientific discoveries...
...rather, it was a problem - but Mac Low and his collaborators may have solved it. In a paper recently submitted to the Astrophysical Journal, they say that the old, Earth-destroying theory was generally accurate but lacked some key details - ones that both reshape theories about how planets form and, oh yes, allow the planet we know best to exist.

...Leap Year Day - Feb. 29, once every four years. But the plane she takes is rerouted to Wales, and she must travel by turbulent boat, crowded bus, creaky old Renault, unpredictable train and occasionally on foot to reach her beau. Meanwhile she discovers true love in the form of Declan (Matthew Goode), an Irish innkeeper she hates at first sight...
...traits we pass on to our children, they are actually very active in our lives every day, regulating how various cells in our bodies behave. In the brain this can be especially powerful. Any significant experience triggers changes in brain genes that produce proteins - those necessary to help memories form, for example. But, says the study's lead author, Ian Maze, a doctoral student at Mount Sinai School of Medicine, "when you give an animal a single dose of cocaine, you start to have genes aberrantly turn on and off in a strange pattern that we are still trying...
...Although Evangelical influence over the DUP has waned in recent years, Evangelical congregations - particularly those in rural Northern Ireland - still form the backbone of the party founded by the Rev. Ian Paisley in 1971. The couple's standing among these devout members is now likely to deteriorate. "The Robinson affair will be difficult for core DUP supporters," says Gladys Ganiel, a lecturer at Trinity College Dublin and author of a book on Evangelicalism in Northern Ireland. "It certainly doesn't hurt to talk about your faith in public in Northern Ireland politics, and no one has done that more than...
