Microsoft Open Technologies: Same Old, Same Old?
Well the shock had barely worn off from the recent news that Microsoft is among the Linux kernel's biggest contributors when another mind-bending announcement was made on a closely related theme. The development this time? None other than Microsoft's declaration last week that it was creating a wholly owned subsidiary devoted to forging closer ties with the open source community. Is it a dream? A nightmare?

'Dancing With The Stars' Latin Night Belongs To William Levy
Latin soap star compared to James Bond after Argentine tango Monday.

With Monday as Latin night on ABC's reality hit show "Dancing With the Stars," it should have been Latin soap star William Levy's week, right? It was.
As the actor and his pro partner Cheryl Burke took on the Argentine tango, Levy played every bit the part of a Latin lover with dance skills, wearing an unbuttoned tuxedo shirt. The judges thought he hit all the right marks — and with a twisted ankle to boot. Carrie Ann Inaba said the actor looked like a "Latin-dancing James Bond." 29/30
Here's how everyone else fared:
Katherine Jenkins and Mark Ballas
Tying Levy at the top was opera singer Jenkins, who also danced the Argentine tango. The judges thought she was perfection and gave her one point shy of a perfect score for her efforts. Head judge Len Goodman said, "This, for me, was like a rose: It had beauty ... but underneath was sharp." 29/30
Maria Menounos and Derek Hough
The TV journalist salsa'd her way to a great performance. The judges told her their dance was passionate, hot and had just the right amount of spice. The pair's routine ended with a hot kiss on the lips. "I don't think you needed the kiss! The salsa is all about the illusion of passion. Don't go at it right in front of us," Inaba said. 27/30
Donald Driver and Peta Murgatroyd
The NFL hot shot danced the Argentine tango, and the judges praised him for his control and execution. Judge Bruno Tonioli said he did a "fantastic job." 27/30
Roshon Fegan and Chelsie Hightower
The Disney star pulled off a routine that wasn't exactly G-rated. But he kept it clean. Goodman told him he moved like "a young guy with his first car." Inaba joked that he was "sexy in a Disney way." 26/30
Jaleel White and Kym Johnson
The childhood TV star danced the samba and bared a pretty impressive six-pack in the process. The judges were impressed by his moves, with Goodman telling him, "Your bum was going like you were chewing toffee." 24/30
Gladys Knight and Tristan MacManus
The soul legend shook her stuff to the samba, and even though the judges were lukewarm on it, they still praised her. Tonioli told her she was magic, while Goodman said her moves were "simple, but effective." 22/30
Melissa Gilbert and Maks Chmerkovskiy
Gilbert did the salsa — a tough feat considering she was injured last week. In her rehearsal segments, she danced around in a neck brace and hard hat. The judges liked her stick-to-itiveness, and Inaba told her it was wonderful to see her gain confidence. Tonioli said she lacked an element of control. "I saw excellent parts and parts that weren't so good," Goodman said. 21/30
Gavin DeGraw and Karina Smirnoff
The pop singer rounded out the bottom. He said in his rehearsal segment that he hoped to continue relying on votes from his fans to keep him in the game. He danced the samba, and the judges weren't too impressed with his moves. "I don't know whether to laugh or cry," Tonioli said before adding, "I actually enjoyed it." The other judges said it was missing key elements. 19/30

Space Shuttle Discovery salutes Washington on historic final flight
As historic flights go, this has to be right up there with the best of 'em. Space Shuttle Discovery performed a final fly-by over the capital, and created a trail of excited spotters as it did so. Perched atop a Boeing 747, the iconic craft was flying at a relatively low 1,500 feet according to NASA. Pictures of the voyage have been popping up on social media and image sharing sites as it headed in from the west, before coming to its final resting place at a special off-shoot of the Smithsonian Institute's National Air and Space Museum near Dulles Airport. Have you spotted Discovery? Be sure to add links in the comments if you do.

Doctors find clue in quest to predict heart attack

WASHINGTON (AP) ? Too often, people pass a cardiac checkup only to collapse with a heart attack days later. Now scientists have found a clue that one day may help doctors determine if a heart attack is imminent, in hopes of preventing it.
Most heart attacks happen when fatty deposits in an artery burst open, and a blood clot then forms to seal the break. If the clot is too big, it blocks off blood flow.
The problem: Today's best tests can't predict when that's about to happen.
"We don't have a way to get at whether an artery's going to crack, the precursor to a heart attack," said Dr. Eric Topol, director of California's Scripps Translational Science Institute.
Wednesday, Scripps researchers reported a new lead ? by searching people's blood for cells that appear to flake off the lining of a severely diseased artery.
Topol's team measured high levels of those cells, deformed ones, floating in the blood of 50 people who'd just had a heart attack. The research is reported in the journal Science Translational Medicine.
Next, Topol said his team soon will begin needed studies to learn how early those cells might appear before a heart attack, and if spotting them could allow use of clot-preventing drugs to ward off damage. Some San Diego emergency rooms will study an experimental blood test with chest-pain sufferers whose standard exams found no evidence of a heart attack, he said.
Don't expect a test to predict heart attacks any time soon ? a lot more research is needed, caution heart specialists not involved with the study. But they're intrigued.
"This study is pretty exciting," said Dr. Douglas Zipes of Indiana University and past president of the American College of Cardiology. It suggests those cells are harmed "not just in the minutes prior" to a heart attack, he said, "but probably hours, maybe even days" earlier.
"It's a neat, provocative first step," added Dr. William C. Little, cardiology chief at Wake Forest Baptist Medical Center. "But it is not a biomarker ready for prime time."
About 935,000 people in the U.S. have a heart attack every year, according to government figures. Doctors can tell who's at risk: People with high blood pressure and cholesterol, who smoke, have diabetes, are overweight or sedentary.
But there's no way to tell when a heart attack is imminent. Tests can spot that an artery is narrowing, or if a heart attack is under way or already has damaged the heart muscle. They can't tell if the plaque inside arteries is poised to rupture.
So it's not that uncommon for someone to suffer a heart attack shortly after passing a stress test or being told that their chest pain was nothing to worry about.
Wednesday's study, funded by the National Institutes of Health, investigated cells shed from the endothelium, or the lining of blood vessels, into the bloodstream. They're called "circulating endothelial cells."
First, Topol's team paired with Veridex LLC, a Johnson & Johnson unit that makes technology used to find cancer cells floating in blood. Could it find these cardiovascular cells, too?
The team took blood samples from 50 heart attack patients ? before they had any artery-disturbing tests or treatments ? and from 44 healthy volunteers. They counted lots of the endothelial cells floating in the heart attack victims' blood, and very little in the healthy people's blood.
The big surprise: The cells in the heart patients were grossly deformed. "Sick cells," is how Topol describes them.
The study couldn't tell when those abnormal cells first appeared ? and that's key, said Wake Forest's Little. It's not clear how many heart attacks happen too suddenly for any warning period.
But Topol theorizes there are plaques that break apart gradually and may shed these cells for up to two weeks before the heart attack. He cites autopsy studies that found people's arteries healed several plaque ruptures before the final one that killed them.
Topol said Scripps and Veridex have filed for a patent for a blood test to detect the abnormal cells.
