The U.S. Supreme Court took up the subject of lying on Wednesday.

Specifically at issue was the constitutionality of a 2006 law that makes it a crime to lie about having received a military medal. But the questions posed by the justices ranged far beyond that — from advertising puffery to dating lies.

That's a 12.76-carat pink diamond that was found at Rio Tinto's Argyle diamond mine in Western Australia. The mine said it is the biggest of its kind found in the country, which is a big deal because that mine produces 90 percent of the global market diamond supply.

The Supreme Court engaged in a lively debate Wednesday when it heard oral arguments in a case testing whether the 2006 Stolen Valor Act is constitutional. The law makes it a crime to lie about military honors.

The Supreme Court has officially declined to decide one of its bigger cases of the term: whether or not doctors, hospitals and other health care providers can sue a state to challenge cuts in the Medicaid health program for the poor.

Terrance W. Gainer, the Senate Sergeant at Arms, sent an email to congressional staff saying that a Senate State office and House District office received a mailing yesterday and a Senate State office received a letter today. Gainer said the letters were postmarked in Portland and the substance was found to be harmless.

Remember last year, when we reported that Italian scientists claimed to have broken the speed of light? Remember the mystical implications of that? The possibility that Einstein was wrong? That our very basic idea of physics was challenged? The idea that you could be shot before a bullet left a gun?

Then you also remember that our friend and astrophysicist Adam Frank warned that these results should be looked at with great suspicion.

Peter Gleick is not just any scientist. He got his doctorate at the University of California, Berkeley and won a MacArthur "genius" award. He is also an outspoken proponent of scientific evidence that humans are responsible for climate change.

And earlier this week, he confessed that he had lied to obtain internal documents from the Heartland Institute, a group that questions to what extent climate change is caused by humans.
