1. JALAPENOS: IS IRRADIATION ONLY FOR RABBIT FOOD?

At the end of a long day do you find yourself dreaming of a big bowl of iceberg lettuce? I don't either. However, the FDA is finally allowing lettuce and spinach to be irradiated at levels that protect against salmonella and E. coli. I don't know what took them so long. The culprit in the most recent salmonella outbreak, however, wasn't salad greens or tomatoes, it was jalapeno peppers. That's more serious. Capsaicinoids in jalapenos trigger the release of endorphins in the brain. Endorphin junkies are forced to deal with shady jalapeno pushers. Irradiation is the safest and most effective sanitation technology that isn't used. In the UK the "natural food" lobby is led by Prince Charles. In the U.S., we have no such excuse.

2. LUNACY: HAS ANYONE THOUGHT THIS THROUGH?

This week, according to today's Science magazine, Senator Obama supported the Bush plan to return humans to the Moon. Replay Apollo? Not exactly; Obama wants a more international effort. You can see how well that worked with the ISS. Meanwhile in Cape Canaveral, McCain was backing the Bush plan to build a successor to the shuttle. Of course, he was in Florida, and that's what politicians all say when they're in Florida, but he did not favor returning to the Moon.

3. BASIC RESEARCH: HAS BELL LABS HIT BOTTOM?

Fifty years ago Bell Labs was the greatest basic research lab the world had ever seen or perhaps ever would see. Enlightened managers recruited top graduates and enforced an absolute rule: their work had to be very relevant to the phone business, or it had to be very, very good. There was no in between. Bell Labs became a national treasure, capturing 6 Nobel prizes and revolutionizing communications. But as Geoff Brumfiel observes in yesterday's Nature, relevant work continues but basic science is all but gone. The cruelest blow came in 2002 at the hands of young German physicist, Jan Hendrik Schoen. He seemed to be able to make a thin layer of organic dye molecules assemble an electric circuit that behaved like a transistor. It's still not clear how much was illusion and how much was delusion, but it wasn't real. (WN 27 Sep 02)

4. ERROR: NORMAN BORLAUG'S 1970 NOBEL PEACE PRIZE.

It has been pointed out to me that I have twice given the date as 2003, which isn't even close. He was awarded the prize in 1970. I was assigned the penance of commenting on the contribution of alcoholic beverage production to atmospheric CO2. It is not clear that there is a contribution. CO2 is a product of fermentation, but CO2 was extracted from the atmosphere to synthesize the sugar.
