The research team of the Public University of Navarre (Basque Country), under the supervision of professor Ramon Gonzalo Garcia of the department of Electric and Electronic Engineering, is participating in a project of the European Space Agency. The final objective is the design of a camera that, working in the range of millimetric frequencies, will be able to obtain images send by different bodies, for example, stars.
The project named “Photonic antenna front-ends: Photonic crystals: Mater
JASON II reaches most of the world ocean floor and sends data ashore via the Internet
A new generation of remotely operated vehicle (ROV) capable of routine operation to depths of 6,500 meters (21,320 feet) and communicating its data back to shore via the Internet has been developed by the Woods Hole Oceanographic Institution (WHOI). The vehicle, JASON II, recently completed its first science cruise off the coast of Washington and Oregon and is currently at sea in the Pacific wo
A large study comparing trucks fueled by natural gas with others fueled by diesel found the natural gas vehicles produced only a quarter of the carbon monoxide emissions and half the oxides of nitrogen emissions of their diesel counterparts.
The study was conducted using package trucks operated by United Parcel Service (UPS), which has the nation’s largest private compressed natural gas (CNG) fleet. The study compared the operations, maintenance, performance, and emissions characteristics
Microchips may be small, but their impact on our world has been huge. And this impact goes beyond the obvious effects of e-mail, cell phones and electronic organizers: A new study shows that the “environmental weight” of microchips far exceeds their small size.
Scientists have estimated that producing a single two-gram chip — the tiny wafer used for memory in personal computers — requires at least 3.7 pounds of fossil fuel and chemical inputs. The findings were reported Oct. 25 on the Web si
Researchers studying the Hedgehog signaling pathway have identified small molecules that could form the foundations of exciting new treatments for Parkinsons disease and certain cancers.
New research published in Journal of Biology – the open access journal for exceptional research – has identified small molecules that are able to stimulate or block the Hedgehog signalling pathway, which is essential to the development, maintenance and repair of cells in the human body. The pot
NASA scientists using satellite data have shown that shifts in rainfall patterns from one of the strongest El Niño events of the century in 1997 to a La Niña event in 2000 significantly changed vegetation patterns over Africa.
Assaf Anyamba and Compton Tucker of NASA’s Goddard Space Flight Center, Greenbelt Md., and Robert Mahoney of Global Science and Technology Inc (GST) analyzed satellite derived images of vegetation from 1997 to 2000. They noticed regions of above normal “greenness” ov
