A University of Colorado at Boulder research team say their discovery of shorelines on Mars is an indication of a deep, ancient lake there and a finding with implications for the discovery of past life on the Red Planet.

Estimated to be more than 3 billion years old, the lake appears to have covered as much as 80 square miles and was up to 1,500 feet deep, roughly the equivalent of Lake Champlain bordering the United States and Canada, said CU-Boulder Research Associate Gaetano Di Achille, who led the study. The shoreline evidence, found along a broad delta, included a series of alternating ridges and troughs thought to be surviving remnants of beach deposits.

Scientists who discovered a beaked, plant-eating dinosaur in China called Limusaurus inextricabilis ("mire lizard who could not escape") say it demonstrates that theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought.  Even more, they write in Nature that it offers important evidence about how the three-fingered hand of birds evolved from the hand of dinosaurs.

It's easy to get lost in a eukaryotic cell. Proteins need to be in the right place at the right time to carry out their functions, but the cell is a crowded place, and the layout isn't exactly simple. Fortunately, the cell has a fairly sophisticated transportation system: if you need to head out of the cell, take the secretory pathway; if your job is to regulate genes, the nuclear shuttle will take you where you need to go.

Some mammoths remained part of British wildlife long after they were believed (scientifically) to have become extinct, according to research published today in the Geological Journal.

Analysis of both the bones and the surrounding environment in Shropshire, England provide the most geologically recent evidence of woolly mammoths in western Europe, they say.
