    Updated: 2011-12-28 01:24:09
    The Moon and Venus make a pretty pair, don’t they? I took this shot myself an hour ago as I write this, about 17:00 local time here in Boulder. I used my cell phone camera, then in Photoshop cropped it to 610 pixels wide (the biggest my blog width will allow) and blurred it a [...]

  • The Genetical Theory of Natural Selection | Gene Expression

    Updated: 2011-12-27 23:15:25
    I flog R. A. Fisher’s The Genetical Theory of Natural Selection a fair amount on this site. You don’t need to understand everything in the book, nor do you have to agree with everything in it, but it is a great point of departure toward understanding evolutionary genetics. I’ve noted that you can get it [...]

    Nodding syndrome, a disease that has sickened more than a thousand children in northern Uganda since the summer, is named for its most distinctive symptom: involuntary, at times violent bobbing of the head, like someone repeatedly nodding yes or snapping out of a doze. Outbreaks of nodding syndrome cropped up in South Sudan this summer, [...]

    If you live in the Northeast, chances are you’ve had a disappointingly balmy December so far (the snow seems to have taken a wrong turn somewhere and wound up over Texas instead). But when the air gets that snap and you  reach for the wool socks, Emily Eggleston at Scientific American has a few factoids [...]

    Updated: 2011-12-23 20:48:54
    Scientists studying satellites orbiting the planet have come to an astounding conclusion: Earth has multiple moons at any given time, the MIT Technology Review reported. Mikael Granvik, along with colleagues at the University of Hawaii, first discovered a mysterious body orbiting the Earth in 2006. The object -- or RH120 as it was known -- turned out to be a tiny asteroid just a few meters across. Moreover, it was a natural satellite just like our moon.

    Updated: 2011-12-09 21:44:17
    The Barringer meteorite crater - known popularly as "Meteor Crater" - near Winslow, Ariz., was formed some 50,000 years ago in the flat-lying sedimentary rocks of the Southern Colorado Plateau in Arizona. Now, scientists are using the crater to study mysteries near and far. This out-of-the-blue geological feature is considered a prime example of a young, well-preserved and well-documented simple impact ...

The planet, Kepler 22-b, lies about 600 light-years away and is about 2.4 times the size of Earth, and has a temperature of about 22C. It is the closest confirmed planet yet to one like ours - an "Earth 2.0".

    Astronomers have found 18 new alien planets, all of them Jupiter-size gas giants that circle stars bigger than our sun, a new study reports. The discoveries increase the number of known planets orbiting massive stars by 50 percent. The exoplanet bounty should also help astronomers better understand how giant planets form and grow in nascent alien solar systems, researchers said.
