Life under Arctic ice

Ever wonder what lies beneath the polar ice? Turns out several researchers did as well. This past July a team of scientists led an expedition designed to image life under sea ice. The video below was captured with the Nereid Under Ice (NUI) vehicle and shows brown algae living on the bottom of sea ice…

Will bees save us from baldness?

  Propolis is a resin-like compound honeybees collect to coat their hives. New research suggests that this compound may increase hair growth as observed in studies of mice.

New research from Vanderbilt University shows that hummingbirds and insects have a lot in common…when it comes to flying at least.

Using 3D simulations of…

Creating Healthier Turkeys

Did you know that the typical Thanksgiving day broad-breasted white turkey develops in as little as 136 days (on average)?

Here is a list of things to do after you have installed Ubuntu 14.10 Utopic Unicorn. There is some discussion of whether or not you should upgraded to 14.10 here, but the short version is, for most people an upgrade from 14.04 is not necessary but not a bad idea, and an upgrade from any…

Last summer we were driving up north, in our Prius, and one of those coal rollers tailgated us for a while, then passed us. On the right. On the median. Jerk. When we were trying to decide whether or not to buy a Prius, last winter, I looked into the usual things one looks into.…
