About 300 million years ago, volcanic ash buried a tropical forest located in what is now Inner Mongolia, much like it did the ancient Roman city of Pompeii.

QUITO, ECUADOR--Long before the Spanish conquered the Incas in 1533, and centuries before the Incas inhabited this area, the present-day site of Quito International Airport was a marshy lake surrounded by Indian settlements--the Quitus on one shore and the Ipias on the other. Between A.D. 200 and 800 these cultures prospered here, fishing the lake, growing corn, beans and potatoes in the fertile soil, and fermenting an alcoholic drink-- chicha --made of a watery corn broth.

Crickets make a big contribution to the sounds of a summer night. And they’ve been doing so for some 165 million years. Now paleontologists have reconstructed the song of a long-extinct bushcricket--based on its remains.

The Bodele depression at the southern edge of the Sahara is a fearsome, forsaken place. Winds howl through the nearby Tebesti Mountains and Ennedi Plateau, picking up speed as they funnel into a parched wasteland nearly the size of California. Once there was a massive freshwater lake here. Now the lake is a shrunken puddle of its former self. Across most of the landscape, there is nothing.

People have used tobacco for well over a thousand years. And researchers recently found unique physical evidence of the ancient habit. They detected traces of tobacco in a 1300-year-old Mayan container. The work is in the journal Rapid Communications in Mass Spectrometry . [Dmitri V. Zagorevski and Jennifer A. Loughmiller-Newman, " The detection of nicotine in a Late Mayan period flask by gas chromatography and liquid chromatography mass spectrometry methods "]

The transition from single-celled to multicellular organisms was one of the most significant developments in the history of life on Earth. Without it, all living things would still be microscopic and simple; there would be no such thing as a plant or a brain or a human. How exactly multicellularity arose is still a mystery, but a new study, published January 16 in Proceedings of the National Academy of Science s, found that it may have been quicker and easier than many scientists expected.

Theoretical physicist Paul Steinhardt did not expect to spend last summer travelling across spongy tundra to a remote gold-mining region in north-eastern Russia. But that is where he spent three weeks tracing the origins of the world’s only known natural example of a quasicrystal--an exotic type of structure discovered in 1982 in a synthetic material by Dan Shechtman, a materials scientist at the Israel Institute of Technology in Haifa who netted the 2011 Nobel Prize in Chemistry for the finding.
