Press releases are a uniformly terrible means of communication, and press releases about science are worse because they lack all of the science. I guess they’re not quite as bad as newspaper articles about press releases about science, but that’s not saying much. Anyway, you have to read the paper; nothing else matters.

But it’s no good reading the press release.
