Massachusetts General Hospital in Boston has disciplined three child psychiatrists for failing to declare payments worth millions of dollars from drug companies. The most prominent, Joseph Biederman, pioneered drug treatment for bipolar disorder in children. The three have apologised and say their "mistakes were honest ones". A backlash has begun against a proposal to replace the constant pi. Tau supporters say their constant, equal to two pi, makes calculations simpler.
