No, said airline security, you can't take this bottle onboard. It exceeds the 100 milliliter limit; it's forbidden.
But wait, said professor Martin Birchall of Bristol University. This is a medical container. Inside is a trachea, a carefully constructed human windpipe, seeded with 60 million stem cells from a very sick woman in Barcelona. We have just 16 hours to get it into her body. We pre-arranged this.
We have no record of your request, said the airline.
The famous paintings on the walls of caves in Europe mark the beginning of figurative art and a great leap forward for human culture.
But now a novel method of determining the age of some of those cave paintings questions their provenance. Not that they're fakes — only that it might not have been modern humans who made them.
The first European cave paintings are thought to have been made over 30,000 years ago. Most depict animals and hunters. Some of the eeriest are stencils of human hands, apparently made by blowing a spray of pigment over a hand held up to a wall.

After Moody's became the second ratings agency to downgrade Spain's sovereign debt, the country's borrowing costs skyrocketed to record highs.
"The interest rate — or yield — on the country's benchmark 10-year bonds rose to a record 6.96 percent in early trading Thursday, its highest level since Spain joined the euro in 1999 and close to the level which many analysts believe is unsustainable in the long term," the AP reports.
A day after getting approval for a financial rescue he vowed Spain would never need, Prime Minister Mariano Rajoy said it was his idea all along.
"No one pressured me into this. I pushed for it myself, because I wanted a line of credit," Rajoy said. He refused to call it a "bailout." He called it a "victory" instead.
Most Spaniards don't buy that. In a poll published Sunday, 78 percent of respondents said they have "little or no" faith in Rajoy and his ruling conservatives. That's just six months after they won elections in a landslide.
