Frontline: The Warning

Frontline: The Warning

As head of the Commodity Futures Trading Commission [CFTC], Brooksley Born became alarmed by the lack of oversight of the secretive, multitrillion-dollar over-the-counter derivatives market. Her attempts to regulate derivatives ran into fierce resistance from then-Fed Chairman Alan Greenspan, then-Treasury Secretary Robert Rubin and then-Deputy Treasury Secretary Larry Summers, who prevailed upon Congress to stop Born and limit future regulation.

Summers and Geithner got it wrong then and they’re working for Obama now. We have no regulation on any of this stuff yet and the ratings agencies that rated all of this junk AAA aren’t regulated either.

Obama, are you listening? Summers and Geithner have to go.

Doctors Disagree About Effectiveness, Cost of Stents

Doctors Disagree About Effectiveness, Cost of Stents

I heard this piece the other day on All Things Considered. It’s very well produced by Chana Joffe-Walt and beautifully illuminates why cutting healthcare costs is difficult. Two cardiologists disagree on whether stents are over used. Listen to the piece, it’s only 4 minutes long.

One of their biggest disagreements concerns stents, tiny metal tubes that cardiologists use to open clogged arteries and relieve chest pain. Studies show that cardiologists sometimes use stents in scenarios where research would indicate they are unnecessary.

Topol says he believes as many as 20 percent of all stents aren’t really needed. He notes that annually, 1.2 million patients undergo a stent procedure. “Undoubtedly, that’s more than we need to do,” he says.

Sitting in the same California hospital, Teirstein says he’s not convinced by the research Topol leans on. Teirstein is an ardent believer in the technology and puts in an average of seven stents a day. “I definitely have a bias towards stents,” he says. “I have a lot of experience with stents. I’ve seen patients do so much better.”

What if Twitter is leading us all astray in Iran?

What if Twitter is leading us all astray in Iran?

Joshua Kucera speculates on how misinformation can pass through Twitter at the speed of light.

The same “neutral” technology that makes it possible to track many points of view also makes it possible for misinformation to distort the aggregate view or feel of all of the information together.

The wisdom of crowds may have a limit and that limit may have something to do with the speed at which information flows: too fast and there’s no time to think and consider it, too slow and it dies.
