Happy Holidays!

Sorry, I don’t know who to credit for that, I got it from a Facebook post…

Getting cells to revert to a stem-like state – creating so-called induced pluripotent stem (iPS) cells – was a true revolution, but the technique invented in 2006 is only half the game. The first challenges include getting enough adult cells to undergo the “reprogramming” in culture to be of use and removing those traces of…

Scientists have now determined the complete mitochondrial genome sequence of Aoluguya reindeer (Rangifer tarandus). I wonder if the sequence will hold any more clues as to why Rudolph’s nose is so red and bright. Although according to this prior blog entry perhaps it was the other 8 reindeer who were different… Source: Ju Y, Liu H, Rong M,…

Spend a Day With Some of the Nation’s Most Exciting Innovators at X-STEM!

As Dean Kamen, inventor of such amazing technologies as the the Segway human transporter and one of the world’s most advanced robotic arm prostheses, often says: “Our nation is enamored with sports and entertainment, but how can we groom kids to become as passionate about innovation?” At the Festival’s fascinating all-day X-STEM Symposium, presented by MedImmune…

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. Although the researchers did not test propolis on balding mice, they did find faster hair growth in mice that had been shaved or waxed, which is somewhat…

New research from Vanderbilt University shows that hummingbirds and insects have a lot in common…when it comes to flying at least. The researchers placed nontoxic paint on the wing of a ruby-throated hummingbird at 9 different spots then videotaped the animal flying at 1,000 frames per second with 4 cameras simultaneously. 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)? This remarkably quick development is a result of years of selective breeding. The average turkey in 1929 was only about 13 pounds, whereas modern turkeys average around 30 pounds with much of the weight centered in…

Ask the Experts: Growing new limbs

A reader sent me the following question: “How does a lizard grow a new tail?” This was a very timely question as new research has shed light on this very phenomenon. A team of experts at Arizona State University led by Dr. Kenro Kusumi and colleagues have been studying limb regeneration in lizards.   The…

Dear Readers, Find below an interesting press release I may as well share verbatim: The rapidly melting ice sheets on the coast of West Antarctica are a potential major contributor to rising ocean levels worldwide. Although warm water near the coast is thought to be the main factor causing the ice to melt, the process…
