Not long ago, a rare form of iron was found in oceanic crust worldwide dating to about 3.5 million years ago. Astronomers at the time noted that would be consistent with a relatively nearby supernova explosion. Now, another groups of scientists have the same substances incorporated into bacteria dating to the same time: Columbus …

Chalk one up for religious intolerance. Pakistan’s only Nobel Prize winner, Abdus Salam, who pioneered theoretical work leading to the God-damn particle, worships the wrong God, or the wrong prophet, or something.

But the news is likely to be … a little more certainty that the elusive mass lending weirdo particle exists and lives at 125 GeV. Whether the findings will go beyond that is unclear. But it’s still a BFD, because the Higgs …

And by hot I mean 7 trillion degrees. That’s the temperature reached by the Relativistic Heavy Ion Collider or RHIC. Actually 7.2 trillion °F to be precise, making it the hottest temperature acheived by humans, and hotter than anything else we know of in the universe since the first nano-nano second after the bang.

If alien solar systems have giant planets that migrate in close to their star, there won’t be any earthlike planets farther out. At least that’s what a new survey of exosolar systems suggests:
