It fits on a fingertip: Noblella pygmaea is a midget frog, the smallest ever found in the Andes and among the smallest amphibians in the world. Only its croaking was to be heard from the leaves on the mossier ground of the “elfin forests” in the highlands of Manu National Park, before German and Peruvian herpetologists discovered the tiny little thing in south-eastern Peru.  

The popular name of the new species is fitting: Noble’s Pygmy Frog has an average length of 
On the eve of the Passover holiday, researchers from the University of Haifa reveal an exceptional and exciting archaeological discovery that dates back to the time of the People of Israel's settlement in the country: For the first time, enclosed sites identified with the biblical sites termed in Hebrew "gilgal", which were used for assemblies, preparation for battle, and rituals, have been revealed in the Jordan valley.
Saturn's largest moon, Titan, may have a subterranean ocean of hydrocarbons and some topsy-turvy topography in which the summits of its mountains lie lower than its average surface elevation, according to new research. 

Titan is also more squashed in its overall shape—like a rubber ball pressed down by a foot—than researchers had expected, said Howard Zebker, a Stanford geophysicist and electrical engineer involved in the work. The new findings may help explain the presence of large lakes of hydrocarbons at both of Titan's poles, which have been puzzling researchers since being discovered in 2007. 
The latest data from NASA and the University of Colorado at Boulder's National Snow and Ice Data Center show the continuation of a decade-long trend of shrinking sea ice extent in the Arctic, including new evidence for thinning ice as well.

The researchers, who have been tracking Arctic sea ice cover with satellites since 1979, found that the winter of 2008-09 was the fifth lowest maximum ice extent on record. The six lowest maximum events in the satellite record have all occurred in the past six years, according to CU-Boulder researcher Walt Meier of NSIDC.

Researchers at Eindhoven University of Technology (TU/e) have developed an entirely new method for starting chemical reactions. For the first time they used mechanical forces to control catalytic activity – one of the most fundamental concepts in chemistry. This allowed them to initiate chemical reactions with mechanical force. This discovery paves the way to developing materials capable of repairing themselves under the influence of mechanical tension. The results of their research were published in Nature Chemistry.

As science fiction plot lines go, the unintended consequences of yielding tasks too complicated or dangerous for human hands to computers and robots is a popular one. Yet real life scientists are increasingly doing just that, creating automated systems and devices that can not only help collect, organize and analyze scientific data, but that are also able to intelligently and independently draw up new hypotheses and approaches to research based on the data they receive.

Writing in Science, David Waltz of the Center for Computational Learning Systems at Columbia University and Bruce G. Buchanan of the computer science department at the University of Pittsburgh discuss this 'brave new world' of scientific research and its implications for the way science is conducted.
