* "Unable to verify referring url. Please go back and try again" Problem Logging In?

If you get an "Unable to verify referring url. Please go back and try again" error when you try to log in, you need to be sure you are accessing the board with a url that starts with "https://ecauldron.com".  If it starts with https://www.ecauldron.com" (or "http://www.ecauldron.com") you will get this error because "www.ecauldron.com" is not technically the same website as "ecauldron.com". Moving to the more secure "https" means it is more picky about such things.

NASA: "Building blocks of life" found on Mars.

Curiosity's latest data reveal that the watery lake that once filled Mars’s Gale Crater contained complex organic molecules about 3.5 billion years ago. Hints of them are still preserved in sulfur-spiked rocks derived from lake sediments. Sulfur may have helped protect the organics even when the rocks were exposed at the surface to radiation and bleach-like substances called perchlorates.
Not conclusive. But.

Oh, and:

In addition to ancient carbon, Curiosity has caught whiffs of organics that exist on Mars today. The rover has periodically sniffed Mars’s atmosphere since it landed, and in late 2014, researchers using these data showed that methane—the simplest organic molecule—is present in Mars’s atmosphere.

Methane’s presence on Mars is puzzling, because it survives only a few hundred years at a time, which means that somehow, something on the red planet keeps replenishing it. “It’s a gas in the atmosphere of Mars that really shouldn’t be there," says NASA Jet Propulsion Lab scientist Chris Webster.
