DNA Study Indicates Neandertals & Humans Interbred
 
[url=http://www.aolnews.com/science/article/neanderthals-and-humans-interbred-scientists-say/19467237]Scientists Discover New Proof of the Neanderthal Within[/url]:

[i]It turns out there really is a little caveman in a lot of us.An international team of scientists has for the first time decoded the complete Neanderthal genome, and the results, to be reported in the May 7 issue of Science, offer new insights into our closest evolutionary relatives and an exciting new way to explore the genetic basis of what makes humans unique. But the big news? The scientists also found evidence that humans and Neanderthals interbred. And the results of that prehistoric coupling can be found in most people's DNA.[/i]

C-Diff Goes Airborne
 
[url=http://www.nytimes.com/2010/05/25/health/25infect.html?src=me&ref=health]New Way Bacterium Spreads in Hospital[/url]
[quote]Health care workers and patients have yet another source of hospital-acquired infection to worry about, British researchers are reporting.

Clostridium difficile, a germ that causes deadly intestinal infections in hospital patients, has long been thought to be spread only by contact with contaminated surfaces. But a new study finds that it can also travel through the air.

The researchers emphasized that there is no evidence that C. difficile can be contracted by inhaling the germs. Rather, they float on the air, landing in places where more people can touch them.

The bug is commonly spread by contact with infected feces, and the British scientists said the new study made it even more urgent to isolate hospital patients with diarrhea as soon as possible — even before tests confirm a C. difficile infection.

“We don’t want people to wait for the confirmation,” said the study’s senior author, Dr. Mark H. Wilcox, a professor of medical microbiology at the University of Leeds. [b]“By then, the cat’s out of the bag.”[/b][/quote]

My favourite metaphor :poop:

As for the bolded text, he meant:
"By the time the cat is out of the bag, the horse has bolted".

[QUOTE=ewmayer;216227]... "the shit has hit the fan" ...[/QUOTE]Erm, do you mean that the unwanted brown pungent waste matter has hit the rotating air displacement device?

:threadhijacked:

So now we need a thread to enumerate all the possible expansions of "the shit has hit the fan".

[QUOTE=cheesehead;216551]"Giant airplane-mounted telescope sees first light!"[/QUOTE]Finally. I was sad that the [URL="http://en.wikipedia.org/wiki/Kuiper_Airborne_Observatory"]KAO[/URL] was taken out of service to help fund this. The importance of having a major telescope that one can move to a specific ground track is huge.

"BREAKING: Another Jupiter impact?"

[URL]http://blogs.discovermagazine.com/badastronomy/2010/06/03/breaking-another-jupiter-impact/#comments[/URL]

[quote][I][Update (19:00 Mountain time): [B]CONFIRMED[/B]! [URL="http://www.unmannedspaceflight.com/index.php?showtopic=6626&view=findpost&p=160510"]A poster on the Unmanned Space Flight forum reports[/URL] that another amateur astronomer, [URL="http://astro.christone.net/"]Christopher Go[/URL] (link goes to home page, no news there yet) has confirmed Anthony Wesley's observation and [URL="http://astro.christone.net/jupiter/jupiterimpact.wmv"]also has video[/URL]. Though I'm having some trouble playing it, I did see the flash in the video. I think it's safe to call this one real!]


[/I][I][UPDATE 2: Wesley [URL="http://jupiter.samba.org/jupiter/20100603-203129-impact/jupiter-fireball-20100603.avi"]has put up his video[/URL], and it's [B]very[/B] cool. The impact is, um, pretty obvious. Bright, too, which makes me think this was a significant object. I'm very surprised at how quickly it brightens and fades, though; I'd expect the flash from the object itself to last a few seconds, and then to see some sort of glowing plume. Perhaps the object itself was a small comet or a loosely packed asteroid -- a so-called "rubble pile " -- which fell apart and vaporized while still high in the atmosphere. I'm guessing, so I'll wait and see what the experts say soon.[/I]]

In what turns out to be a major coincidence, Anthony Wesley, an amateur astronomer in Australia, [URL="http://www.iceinspace.com.au/forum/showthread.php?t=61965"]is reporting[/URL] that he recorded another impact on Jupiter! This time he has video of the impact, which he claims was quite bright and lasted about two seconds.[/quote]
