Submission + - Engineer Designs His Own Heart Valve Implant (popsci.com)

nametaken writes: In 2000, Tal Golesworthy, a British engineer, was told that he suffers from Marfan syndrome, a disorder of the connective tissue that often causes rupturing of the aorta. The only solution then available was the pairing of a mechanical valve and a highly risky blood thinner. To an engineer like Golesworthy, that just wasn't good enough. So he constructed his own implant that does the job better than the existing solution--and became the first patient to try it.

Heroic Engineer Crashes Own Vehicle To Save a Life 486

scottbomb sends in this feel-good story of an engineer-hero, calling it "one of the coolest stories I've read in a long time."

He knew a busy intersection was just ahead, and he had to act fast. Without consulting the passengers in his minivan — 'there was no time to take a vote' — Innes kicked into engineer mode. 'Basic physics: If I could get in front of him and let him hit me, the delta difference in speed would just be a few miles an hour, and we could slow down together,' Innes explained."

But yesterday at an exoplanet meeting in Turin, Italy, Switzerland-based astronomers announced that they could find no trace of the prized planet in their observations of the same planetary system.
