Tiny Bubbles
Time for a mild science catfight over hot bubbles.When the force of sound waves implode tiny bubbles within a liquid at room temperature, the surface of the bubble can reach temperatures at least 25,000 degrees Fahrenheit, more than twice as hot as the surface of the sun, scientists reported this month.I can feel the sizzle from here. It feels....sassy.
The center of such a bubble may be even more astonishingly hot.
The only known attempt to reproduce the Oak Ridge experiment was by Dr. Seth Putterman of the University of California, Los Angeles, whose the work was financed by an unusual source, the BBC. For an episode of its "Horizon" science series that focused on the Oak Ridge experiment, the BBC gave Dr. Putterman $70,000 to try to replicate it.Rowr!

But his experiment saw no sign of the fusion-generated neutrons that had been reported.
Dr. Rusi P. Taleyarkhan, the head of the Oak Ridge experiment, said there were notable differences between his set-up, which cost close to $1 million, and the one put together by Dr. Putterman. "Sometimes you get what you pay for," said Dr. Taleyarkhan, now a professor of nuclear engineering at Purdue.

His work was not "financed by an unusual source, the BBC", his work was financed by British taxpayers.
