Scouring the genome of a wild Mexican potato, scientists have discovered a gene that protects potatoes against late blight, the devastating disease that caused the Irish potato famine.

The discovery of the gene and its cloning by scientists at the University of Wisconsin-Madison was reported today (July 14) in online editions of the Proceedings of the National Academy of Sciences (PNAS).

The identification of the gene, found in a species of wild potato known as ´ Solanum bulboca

United Nations-led development efforts in some of the poorest and most remote parts of the globe are being guided by images from space.

The ESA-backed UNOSAT consortium is providing an average of five new satellite-derived maps or data products to UN agencies and non-governmental organisations every week.
The poor Nicaraguan highlands municipality of Matagalpa is just one site among many where UNOSAT-supplied geographical information system (GIS) tools are being used in develop

Astronomers looking for planetary systems that resemble our own solar system have found the most similar formation so far. British astronomers, working with Australian and American colleagues, have discovered a planet like Jupiter in orbit round a nearby star that is very like our own Sun. Among the hundred found so far, this system is the one most similar to our Solar System. The planet’’s orbit is like that of Jupiter in our own Solar System, especially as it is nearly circular and there

In less than a month, researchers at USC’s Information Sciences Institute and collaborators nationwide have built one of the world’s best systems to translate Hindi text into English and query Hindi databases using English questions.

This effort was part of the “Surprise Language” project, a test of the computer science community’s ability to create translation tools quickly for previously unresearched languages sponsored by the Defense Advance Research Project Agency (DARPA). The ex

Web users are picky and impatient, typically visiting only the first three results from a query, with one in five searchers spending 60 seconds or less on a linked Web document, according to Penn State researchers.

“People make instantaneous judgments about whether to stay on a site, and if a site doesn’t the give the right impression, users will bypass it,” said Dr. Jim Jansen, assistant professor in Penn State’s information sciences and technology (IST). “A page has to be well-d

Lawrence Berkeley National Laboratory (Berkeley Lab) scientists have developed the world’s first x-ray computed tomography (CT) scanner capable of examining entire core samples at remote drilling sites. The portable device, which employs the same high-resolution imaging technology used to diagnose diseases, could help researchers determine how to best extract the vast quantities of natural gas hidden under the world’s oceans and permafrost.

The scanner images the distribution of gas hydrate
