What Does A Black Hole Sound Like?
Sept. 9, 2003: Astronomers using NASA’s Chandra X-ray Observatory have found, for the first time, sound waves from a supermassive black hole. The “note” is the deepest ever detected from any object in our Universe. The tremendous amounts of energy carried by these sound waves may solve a longstanding problem in astrophysics.
The black hole resides in the Perseus cluster of galaxies located 250 million light years from Earth. In 2002, astronomers obtained a deep Chandra observation that shows ripples in the gas filling the cluster. These ripples are evidence for sound waves that have traveled hundreds of thousands of light years away from the cluster’s central black hole.
“The Perseus sound waves are much more than just an interesting form of black hole acoustics,” says Steve Allen, of the Institute of Astronomy and a co-investigator in the research. “These sound waves may be the key in figuring out how galaxy clusters, the largest structures in the Universe, grow.”

That thing you see in this person abdomen is part of her skull.
The abdomen in question belongs to former “Mrs. Idaho” Jamie Hilton. Back in June, Hilton was involved in a devastating accident, and had to undergo emergency brain surgery. In the process, her doctors removed 25% of her skull so that her severely swollen brain would have room to return to its normal size. Fully intending to reattach the skull fragment later, Hilton’s doctors stowed it away inside her stomach, where her body would keep it nourished until she was ready to have it reattached.
In the weeks ahead, Hilton recovered marvelously, all while missing a full quarter of her skull. She wore a helmet to help prevent further injury.
By mid-July, Hilton’s swelling had subsided enough for doctors to remove the fragment from her abdomen and put it back in place with the aid of some titanium screws and plates. It’s been over two months since her second surgery, and seems to be doing incredibly well, telling the New York Post that the only lasting effect seems to have been a change in her tastebuds and the loss of her sense of smell.
As for her head, it’s back to its normal shape, albeit with a pretty awesome-looking scar.
You can read more about Hilton’s remarkable healing process over on her blog, where she and her husband have catalogued the entire ordeal. For more information on the surgery that Hilton had performed (decompressive hemicraniectomy), check out this post by Bradley Voit, who wrote about the procedure in detail when Congresswoman Gabby Giffords had it performed back in January 2011.
Fuck yeah, modern medicine!

MEDICINE IS SO COOL.
This is amazing, inspiring, and ahhh! so many feels!
With the science world all abuzz in anticipation of tomorrow’s official announcement from CERN in regards to its hunt for the Higgs, some of you may be wondering, “what’s a Higgs?” And for that matter, what’s a boson?
The video above, released a couple of months ago by the talented Jorge Cham at PHDcomics, gives a entertaining run-down of subatomic particles, how they interact and how, if it exists — which, by now, many are sure it does — the Higgs relates to them.
It’s the 7-minutes course in particle physics you’ll wish you had taken in college (unless you’re a particle physicist in which case… well, you’d still probably have enjoyed it.)
This is absolutely pathetic.

Hey Heartland: not only do many average people ‘believe’ in global warming, but so do 97% of climate scientists.

Can one person experience love more deeply than another? That’s what The Stanford Center for Cognitive and Neurobiological Imaging and filmmaker Brent Hoff set out to understand when they hosted the 1st Annual Love Competition. Seven contestants, ranging from 10 to 75 years of age, took part. And they each spent five minutes in an fMRI machine, thinking deeply about love and allowing the imaging technology to measure activity in their dopamine, serotonin and ocytocin/vasopressin pathways. If you think this sounds unromantic, you’ll want to reserve judgment. Though science may be the explicit focus here, the film has a touching human dimension to it. (via openculture.com)
