Cary Grant's chin may appeal to you and Ingrid Bergman. But that might not be the case among the indigenous people of Australia.
And the idea that a guy's jutting jawline might not cause women the world over to swoon calls into question the notion that some characteristics are pretty much automatic signals of desirability for prospective mates, researchers say.
Scientists reported Wednesday that they had developed a way to measure how much pain people are experiencing by scanning their brains.
The researchers hope the technique will help doctors treat pain better, but the work is also raising concerns about whether the technique might interfere with doctors simply listening to their patients.
Now, when someone is in pain, a doctor has no way to judge its severity except to ask questions, a method that often is inadequate.
On a normal day, Kansas City, Mo., processes more than 70 million gallons of raw sewage. This sewage used to be a nuisance, but Kansas City, and a lot of municipalities around the country, are now turning it into a resource for city farmers hard up for fertilizer.
After the sewage has been processed at a treatment plant, it's piped out to Birmingham Farm on the north side of the Missouri River.
How much oxygen should severely premature infants receive? A study that sought to answer the question has been criticized for not fully informing parents about the risks to their children.
Federal officials say a large study of premature infants was ethically flawed because doctors didn't inform the babies' parents about increased risks of blindness, brain damage and death.
The study involved more than 1,300 severely premature infants at nearly two dozen medical institutions between 2004 and 2009. The infants were randomly assigned to receive two different levels of oxygen to see which was better at preventing blindness without increasing the risk of neurologic damage or death.

Roasted fish on a stick is OK, but wouldn't it be nice to be able to cook up some fish soup?
That's what might have crossed the minds of hunter-gatherers who made the world's first cooking pots. A new analysis of pottery made 15,000 years ago in what's now Japan reveals that it was used to cook seafood, probably salmon.
A few months ago on Radiolab, we did an hour on color, which included a segment on rainbow watching. We imagined a man, a dog, a sparrow and a butterfly all gazing at the same rainbow and we asked: How many colors does each see?

The man whose research led to the world's first test-tube baby more than three decades ago, has died at age 87.
Robert Edwards, who later won the Nobel Prize, began experimenting with in vitro fertilization, or IVF, in the late 1960s. His work, controversial at the time, eventually led to the birth of the world's first "test tube baby," Louise Brown, on July 25, 1978.
Since then, IVF has resulted in about 5 million babies worldwide, according to the European Society for Human Reproduction and Embryology.
