One way in which scientists use carbon isotopes found in fossils to identify the sites of ancient rain forests may not work as expected.

A new project will investigate the relationships between tectonics, climate and the evolution of humans’ primate ancestors in Kenya’s Turkana Basin.
The “walking rock” track suggests that a massive volcanic winter may have frozen the tropics during the dawn of the dinosaur age.
Scientists have long determined what extinct animals ate by analyzing carbon isotopes locked inside their fossil teeth. But a new study shows that in many cases, they may be plugging the wrong numbers into their equations. The findings may change some views of how mammals, including us, evolved.
Paleontologists Are Unzipping Our Genes
Recently, paleontologists have used genomics to delve into the lives of ancient humans. These studies have capitalized on futuristic techniques to reveal the genealogy, travel plans and sex lives of our ancestors.
Earth Institute field researchers study the planet on every continent and ocean. Projects are aimed at understanding the fundamental dynamics of climate, geology, ecology, human history and more. Here is a partial list of upcoming expeditions.
Dennis Kent, a leading expert in the history of earth’s magnetic field, has been elected to the American Academy of Arts and Sciences. Other members of the 2012 class include U.S. Secretary of State Hillary Rodham Clinton, playwright Neil Simon, Hollywood director Clint Eastwood and Amazon founder Jeffrey Bezos.
In 1968, 14-year-old Paul Olsen of suburban Livingston, N.J., and his friend Tony Lessa heard that dinosaur tracks had been found in a nearby quarry. They raced over on their bikes. “I went ballistic,” Olsen recalls. Over the next few years, the boys uncovered and studied thousands of tracks and other fossils there, often working into the night. It opened the… read more
