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.

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.

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.

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.

Note: We've updated the headline on this post for the sake of clarity. To be clear, it's the apple and pear tree blossoms that get sprayed with antibiotics, not the fruit itself.

Apples and especially pears are vulnerable to a nasty bacterial infection called fire blight that, left unchecked, can spread quickly, killing fruit trees and sometimes devastating whole orchards.

Bitcoin, the digital currency that trades outside the control of central banks and international borders, reached new heights Tuesday, surpassing the $200 mark for the first time. That level comes just five days after bitcoin approached $150, a development that Mt.Gox, the largest exchange service for the currency, deemed to be "epic."

Bitcoin's rise has been sharp. It was only two months ago that exchange rates put a single bitcoin's value at around $20.

Google announced Tuesday that its Google Fiber project would be hitting Austin, Texas, next. The company says Austin, famous for its South by Southwest festival, is a "mecca for creativity and entrepreneurialism, with thriving artistic and tech communities."

Google Fiber is the tech giant's blazing fast Internet service, with current rates at 1 Gpbs, about 100 times faster than your typical cable broadband Internet service. It debuted in Kansas City in 2012.
