This isn't a painting. It's not from a movie. It's not a strange astronomical event. This is real — what you can see when certain helicopters in Afghanistan touch down on sandy ground, raising dust, causing mysterious arcs of light to loop and dance through the air.
This doesn't always happen. "The halos usually disappear as the rotors change pitch," wrotewar photographer Michael Yon. "On some nights, on this very same landing zone, no halos form." How come?
In a long-awaited chronicle of its involvement in the prosecution of the late Internet activist Aaron Swartz, Massachusetts Institute of Technology officials released a 180-page report saying administrators never "targeted" the programmer and committed no wrongdoing.

The dazzling array of food options at the Googleplex campus in Mountain View, Calif. — 25 cafes at last count — is the much-cited example of tech world food perks.

Fewer than 10 percent of all mammal species are monogamous. In fact, biologists have long disagreed over why monogamy exists at all. That's the subject of two studies published this week — and they come to different conclusions.
Animals that leave the most offspring win the race to spread their genes and to perpetuate their lineage. So for most mammals, males have a simple strategy: Mate with as many females as possible.
"Monogamy is a problem," says Dieter Lukas, a biologist at Cambridge University. "Why should a male keep to one female?"

At Margaret O'Keefe's farm in East Texas, they grow high-quality Bermuda grass. The fields are flat and vibrant green, surrounded by woods of a darker, richer green. The family loves this land. O'Keefe inherited it from her mother, who divided it among eight children.
"She used to call it 'enchanted valley,' " O'Keefe says.
But her "enchanted valley" also lies in the path of the Crosstex NGL Pipeline.
