Up next, an entirely different kind of food problem. Recycling paper and plastic, as you know, is an effective way to save money and energy. So why not recycle all the uneaten food that goes to waste? And there is an awful lot of it. Forty percent of the food in the U.S. today goes uneaten, which means Americans are throwing out the equivalent of 165 billion - with a B - billion dollars worth of food each year. But that's not all. Food waste, as it decays in landfills, also produces methane, which is a potent greenhouse gas.

This is SCIENCE FRIDAY. I'm Ira Flatow. Over 115,000 Americans are currently waiting for an organ transplant, and most of them are in need of a kidney. Now, what if we could just create a kidney for them in the laboratory? One of my next guests has experimented with printing out organs using an inkjet printer, but instead of ink, he uses cells.

Mathematician Ian Stewart joins the Science Friday Book Club meeting to discuss Edwin Abbott's classic Flatland. The book, published in 1884 under the pseudonym "A. Square," tells the story of a two-dimensional world where women are straight lines and men are polygons.

Salt — it's the ultimate condiment. It's the only rock we eat, and it makes our food taste better. There are dozens of varieties, from hand-harvested Himalayan pink to plain-old kosher, to various herb-infused blends. But, as we report a lot around here, when we eat too much, it can be bad for our health.

Before we go slow, let's go fast, so fast you can't go any faster. That would be light in a vacuum, traveling at 670 million miles per hour ...

Light, of course, can slow down. When light passes through water, it loses speed. A diamond is an even better speed bump. It can slow a beam of light by 40 percent.

But moving on, you and I are going pretty fast right now, though we don't notice. The planet we're on is zipping around the sun at 66,000-plus miles per hour ...

A man-made bat cave in Tennessee is looking for tenants. An hour northwest of Nashville, the artificial cave is built to give thousands of bats a haven from a devastating infection called white-nose syndrome.

Millions of bats in the Northeast have died from the infection since it first showed up a few years ago. The culprit is an invasive fungus that grows in caves. When bats hibernate inside, they wake up with faces covered in white fuzz and often wind up starving or freezing to death.

There's some big news out today about one of the most sensitive issues in medicine: Who's next in line for a transplant?

The United Network for Organ Sharing, or UNOS, a nonprofit in charge of distributing organs, wants to revamp the system for distributing the most sought-after organ — kidneys — for the first time in 25 years.

A federal court has awarded a Denver man $7.2 million in a lawsuit he filed against a popcorn maker and a grocery store for selling him microwaved popcorn that made him sick.
