A farm in Iowa is going to destroy more than five million of its chickens in an attempt to curb the spread of the highly infectious avian flu.
The U.S. Department of Agriculture confirmed the H5N2 avian influenza outbreak Monday, adding that the agency says that there is little chance that humans could become infected. According to the department's press release:
In Hawaii, a battle is going on over the future of a mountaintop. Native Hawaiians say it's sacred ground, while astronomers say it's the best place in the world to build a massive, 18-story telescope.
This is not simply a story of religion versus science. Activists consider the construction of a giant telescope on the island of Hawaii to be a desecration of their sacred land.
When I was a young astrophysics grad student, I'd return home a couple of times a year. Eating dinner with some of my extended family, one of my great aunts would invariably ask why, at age 28, I was still in school.
I'd tell her about my work studying the evolution of stars — how they're born, how they die. But no matter how poetic or uplifting I tried to make my explanations, she'd always bring the conversation to an abrupt halt with the same question: "So what's it good for?"

"They're running a little late," chides an elderly gentleman, tapping his watch at 12:02 p.m. He's come to this farm near the Danish city of Ikast, along with about 1,500 others, to celebrate what has become something of a national holiday in Denmark. It's the Sunday in mid-April when thousands of organic dairy cows at 75 farms across the country are released into the green fields of spring. At exactly noon. Eh hem.
We associate technology with the shiny and new. But humans have been using technology to change the environment and themselves since at least the lower Paleolithic period, when our ancestors were making stone tools.
Is the technology of today fundamentally different? In particular, does it change the way we think of ourselves or our relationships to each other and the environment? Does it change the way we think about what exists (metaphysics), about what and how we can know about it (epistemology), or about how we ought to live (ethics)?
Last week, as a big storm bore down on Rockford, Ill., students in a Purdue University classroom prepared to track its effects using Twitter.
Using software jointly developed by Purdue, the Department of Homeland Security and the National Weather Service, they huddled around laptops to analyze a tiny sample of the tweets from the storm's immediate vicinity. They were looking for keywords like "damage" or "tornado" and for pictures of funnel clouds.
