The trajectories of life-bearing meteorites from Earth.

Some Japanese researchers did the math on the fate of the billions of tons of rocks and water that were tossed into space when Earth was hit by an asteroid 65M years ago. It turns out that much of that material probably bore life, and it wound up not just on the Moon, but also on on Mars and the moons of Jupiter and Saturn. Some of the ejecta (about 1,000 rocks) would have even wound up on an Earth-like planet orbiting a red dwarf star, located 20 light years away. This math tells us that life would only have needed to evolve at 25 sites throughout the Milky Way for these sorts of spores from those planets to have seeded the entire galaxy with life. 

Finally, a link has been shown between pesticides and colony collapse disorder.

It’s been hypothesized that pesticides are the source of the global collapse of bee populations, but there had been no controlled experiments demonstrating correlation. A French government group performed just such an experiment and found that, indeed, colonies exposed to low levels of imidacloprid (a common, Bayer-developed insecticide) failed to thrive. They were 100–200% more likely to die while away from their nests, possibly because imidacloprid damages their ability to navigate back.

  • ThinkProgress: The Conservative Recovery Teeters Into Recession
    17,000 new jobs were created by the private sector last month. 17,000 jobs were eliminated by the public sector last month. Bummed by last month's flatlining of job growth? Thank a congressman.
  • New York Times: Rep. Shelley Berkley’s Cause Is Often Her Husband’s Gain
    She's a strong supporter of (admittedly much-needed) better funding of kidney-care facilities. He's making a fortune on it as a nephrologist. If you ask her, it's just the darnedest coincidence. If you ask an ethicist, it's just plain wrong.
  • List of Virginia Caves
    The most extensive cave system in Virginia is Butler-Sinking Creek, in Bath County, at seventeen miles of total passages. The deepest is 786 feet—that's measured from the highest point to the lowest point—at Burns Cave, in Highland County. That's more than half again as deep as Virginia's tallest building is tall, the 38-story Westin Virginia Beach Town Center

  • Wikipedia: Bunyip
    There's a widespread Australian Aboriginal belief in the "bunyip," a terrifying, water-dwelling mythological creature. It's theorized that these stories arose from occasional discoveries of fossilized bones from any of the many enormous prehistoric marsupials that could be found wandering around Australia until about 40,000 years ago.
  • New York Times: Where Pay for Chief Executives Tops the Company Tax Burden
    A study of the Fortune 100 has found that at least 25 of them paid their CEO more last year than they paid in federal taxes. eBay, Boeing, GE, and Verizon all made the list. This makes it rather difficult to takes seriously claims of excessive taxation of major U.S. businesses.

  • IBM Many Bills: A Visual Bill Explorer
    IBM is doing some really interesting work with legislation here. In my own work on Richmond Sunlight, I've long treated the text of the bill as a black box, doing very little with the text of bills. IBM demonstrates here that there's actually some valuable data to be gleaned from the actual words within the bill. Their interface is lousy—the site is hard to use—by I really admire their original thinking.

    My grandfather kept up with his grandchildren—and we kept up with him—via Facebook until shortly before his death last year. My grandmother had photos and status updates cherry-picked from Facebook and e-mailed to her—delivered via her HP Presto e-mail printer—until her death last month. Of course, the ability to assign grandparents (and grandchildren) to a specific group to limit access is helpful, too—kids need not share everything with their elders.

  • The Washington Post: The shocking truth about the birthplace of Obama’s policies
    Ezra Klein's sensationalist headline aside, it's a fact that the president's agenda is substantially consistent with standard Republican positions in the early nineties. Cap-and-trade, an individual mandate for healthcare, and mixing tax increases and spending cuts for deficit reduction—all sensible conservative positions that Republican leaders are hysterically insisting are the stuff of communism. Conservatives eager to pretend that Obama is a "socialist" or a "Marxist" have tacked so far to the right—giving the president a wide berth—that they're left with Donald Freaking Trump as the most likely get to the the Republican nomination.

  • Discover: Sex, Ys, and Platypuses
    Instead of the XY/XX chromosomes that most mammals have, the platypus has a much more complicated sex chromosomes: five pairs instead of one. The male platypus is XYXYXYXYXY. That's the biggest number of sex chromosomes of any vertebrate. Man, platypus is weird. And so are the others.
  • Christian Science Monitor: Pepsi bottles—no more plastic
    PepsiCo is testing out a plant-based plastic bottle, with the intention of converting all of their bottles from the now-standard polyethylene terephthalate. Coca-Cola says they're doing the same thing. What I'd like to know is whether this material will biodegrade, or if it can be composted. I hope that, at least, it can be recycled, although I'm dubious of municipalities' ability to add a new class of recycling to their systems.
