Last Saturday, SpaceX launched their first manned mission. Astronauts Bob Behnken and Doug Hurley are now aboard the ISS.

So it's one week too late to say Bob and Doug take off, eh?

Quote:The main motivation for this article is that the broader community has decided that Reviewer 2 is a monster. A Google search for “Reviewer 2” produces the interdisciplinary Facebook group “Reviewer 2 Must Be Stopped!” (which has over 9,000 members), a blog entry entitled “How Not to Be Reviewer #2,” and countless images combining almost every visual meme imaginable. In academia, it is fair to say that Reviewer 2 is the ultimate boogeyman. He is Pennywise the Clown, combined with el chupacabra, wrapped in the Blair Witch.

Quote:The lack of iron group elements in SDSSJ1240+6710 suggests that the star only underwent a partial supernova before the nuclear burning died out.

Lead author Professor Boris Gänsicke, from the department of physics at the University of Warwick, UK, said: "This star is unique because it has all the key features of a white dwarf but it has this very high velocity and unusual abundances that make no sense when combined with its low mass.

"It has a chemical composition which is the fingerprint of nuclear burning, a low mass and a very high velocity; all of these facts imply that it must have come from some kind of close binary system and it must have undergone thermonuclear ignition. It would have been a type of supernova, but of a kind that that we haven't seen before."

He said his team's discoveries complement and confirm the current mix of pre-Clovis sites in North and South America, providing evidence of human presence on the continent as old as 26,500 years ago and possibly even to 30,000 years ago.

The discoveries also suggest a great diversity in culture and technologies, he said. "That is what always happens when we find pre-Clovis sites; their artefacts never look the same. We are adding to the vast cultural diversity and provide new arguments that humans were here at least since the beginning of the last glacial maximum (LGM, between 26,500 and 20,000 years ago)," he said.
