There's a book by the novelist China Mieville that describes two cities plopped one on top of the other. One is large-scale, the other smaller-scale, and while they live in entangled proximity, both cities have the same rule. Each says to its citizens, pay no attention — on pain of punishment — to what the "others" around you are doing. See your own kind. "Unsee" the others.

A 26-part series on genetically modified food was not Nathanael Johnson's idea. And he didn't realize it would take six months, either.

Last year, Johnson was hired as the new food writer for Grist, a website for environmental news and opinion. Grist's editor, Scott Rosenberg, was waiting with an assignment: Dig into the controversy over GMOs.

Big, fierce animals — lions and tigers and bears, for example — are relatively scarce in nature. That's normal, because if you have too many, they'll eat themselves out of prey.

But top predators are now so rare that many are in danger of disappearing. That's creating ripple effects throughout the natural world that scientists are still trying to figure out.

What they're exploring is ecology — the interplay of animals and plants in nature. It's not rocket science. It's harder.

It's Not Magic On The Mountain, It's A Rain-Making Machine

A ground-based cloud-seeding tower at Alpine Meadows ski area near California's Lake Tahoe. It spits out silver iodide particles that are the right size and shape to help precipitation form.

The snowpack in the Mountain West this year is at just a small fraction of its normal level. In fact, 2013 was the driest year ever recorded in many parts of California, and there's little relief in sight. But water managers are trying to squeeze every last raindrop out of Mother Nature with a technology developed in the state more than 50 years ago: cloud seeding.

Space Music: How To Hear Solar Flares From The Moon

Live, from the moon, it's the space weather report: Data from a lunar orbiter is being used to create a music stream that reflects conditions in space. Here, an image created by NASA "visualizers" who used data from 2010 to show the moon traveling across the sun, as happens two or three times a year.

We've been following the coronal mass ejection that headed toward Earth after an intense solar flare was emitted from the sun earlier this week. And now NASA tells us that such events can be heard, in a sense, by tuning in to CRaTER Radio, a "sonification" project that uses data from NASA's Lunar Reconnaissance Orbiter to generate musical sounds and stream them on the Internet.
