Scientists study 'talking' turtles in Brazilian Amazon

Turtles are well known for their longevity and protective shells, but it turns out these reptiles use sound to stick together and care for young, according to the Wildlife Conservation Society and other organizations.

New analysis links tree height to climate

What limits the height of trees? Is it the fraction of their photosynthetic energy they devote to productive new leaves? Or is it their ability to hoist water hundreds of feet into the air, supplying the green, solar-powered ...

Scientists fold RNA origami from a single strand

RNA origami is a new method for organizing molecules on the nanoscale. Using just a single strand of RNA, many complicated shapes can be fabricated by this technique. Unlike existing methods for folding DNA molecules, RNA ...

Predicting fracking policy

Hydraulic fracturing is emerging as one of the primary methods of drilling for natural gas, yet is equally controversial in its potential to induce harm to humans and the environment. The uncertainties of the health risks ...

Human contribution to glacier mass loss on the increase

By combining climate and glacier models, scientists headed by Ben Marzeion from the University of Innsbruck have found unambiguous evidence for anthropogenic glacier mass loss in recent decades. In a paper published in Science, ...

Molecular engineers record an electron's quantum behavior

A team of researchers led by the University of Chicago has developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique uses ultrafast ...
