A peregrine falcon.   Thanks to two rich Saudi princes two falcons have had their genomes sequenced.  It was in one of these falcon genomes that we first identified the leptin gene.

The Elusive Bird Leptin: And Now for the Rest of the Story…

Last week the headlines read “elusive bird hormone found” and “discovery of the elusive leptin in birds.”   It has been great to see so much interest … [Continue reading...]

A "young" crater on Mars.  This is a young crater about 30 feet (9 meters) in diameter. How young? The blocks of material ejected from the crater-digging impact sit on top of the sand ripples near the crater. This suggests, from the estimated age of the area's sand ripples, that the crater was formed within the past 100,000 years. The dark sand inside the crater attests to the mobility of fine sand in the recent era in this Meridiani Planum region of Mars.  Image credit NASA/JPL-Caltech

Here is an example of an ash layer from one of the cores of Lake Suigetsu.  This ash layer is more than 1cm thick (the varves are less than 1mm each) and is composed almost almost pure volcanic glass. The purity suggests that it resulted from ash falling from the sky into this very placid lake and quickly sinking to the bottom.  This image is from the Suigetsu web page:

one of my favorite strange fossil elephants.  Like many fossil species this one had two sets of tusks. One of the upper jaw and one on the lower jaw but in this case the lower jaw is greatly extented and the two lower tusks probably acted like shovels.  Image credit: Wired / Tomasz Jedrzejowski
