Scientists reveal new way to make narrower chip patterns

October 6th, 2009 WASHINGTON - New global color maps reveal provocative patterns on the surfaces of Saturn's five innermost large icy satellites, namely, Mimas, Enceladus, Tethys, Dione, and Rhea. These new maps have been presented in a report by Dr.

September 26th, 2009 WASHINGTON - In a new study, scientists have found evidence that climate swings in the northern hemisphere over the past 12,000 years have been tightly linked to changes in the tropics. The scientists found that a prolonged cold spell that caused glaciers in Europe and North America to creep forward several hundred years ago may have affected climate patterns as far south as Peru, causing tropical glaciers there to expand as well.

September 25th, 2009 WASHINGTON - Data from the Moon Mineralogy Mapper (M3), an instrument aboard India's recently ended Chandrayaan-1 spacecraft, along with the Deep Impact spacecraft, has confirmed the existence of water on the surface of the Moon, with scientists explaining the process of its formation. "Water ice on the moon has been something of a holy grail for lunar scientists for a very long time," said Jim Green, director of the Planetary Science Division at NASA Headquarters in Washington.

September 25th, 2009 WASHINGTON - Letter writers of yore had some of the same correspondence patterns as e-mail users today. A new Northwestern University study of human behaviour has determined that those who wrote letters using pen and paper - long before electronic mail existed, did so in a pattern similar to the way people use e-mail today.

September 10th, 2009 WASHINGTON - It is often said that scientists are press shy, and those who aren't, are mavericks. Now, University of Wisconsin-Madison researchers have debunked the theory.

September 3rd, 2009 WASHINGTON - A team of scientists in California have announced the creation of a 'NanoPen' that can simplify the method of laying down patterns of nanoparticles-from wires to circuits-for making futuristic electronic devices, medical diagnostic tests, and other much-anticipated nanotech applications. Writing about their work in ACS' Nano Letters, Ming Wu and colleagues point out that researchers have already developed several different techniques for producing patterns of nanoparticles, which are barely 1/50,000th the width of a human hair.

August 28th, 2009 WASHINGTON - In a new research, scientists have determined that subtle connections between the 11-year-solar cycle, the stratosphere and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, an understanding which would help in predicting the intensity of the Indian monsoon. "It's been long known that weather patterns are well-correlated to very small variations in total solar energy reaching our planet during 11-year solar cycles," said Jay Fein, program director in the National Science Foundation (NSF)'s Division of Atmospheric Sciences, which funded the research.

August 21st, 2009 WASHINGTON - A new study has determined that like police and nurses, cleaner fish on coral reefs wear 'uniforms', which are basically colors and body patterns, to signal their "professions" - a tactic that also helps the fish avoid being eaten by their clients. Several species of small reef fish are known to invite larger fish to stop by "cleaning stations," where the cleaners groom their customers and pick them free of parasites.

August 18th, 2009 WASHINGTON - Scientists have devised a small, cheap, lab-on-a-chip sensor that quickly and accurately identifies sweetness. It can accurately identify the full sweep of natural and artificial sweet substances, including 14 common sweeteners, using easy-to-read colour markers.

June 12th, 2009 WASHINGTON - A new study has determined that an abrupt change in climate, like global warming, can cause a shift in monsoon patterns and hurt agriculture. The study took into account the fact that an abrupt change in climate in the distant past has been associated with a shift of seasonal monsoons to the south, causing more rain to fall over the oceans than in the Earth's tropical regions, and leading to a dramatic drop in global vegetation growth.

June 5th, 2009 WASHINGTON - In a new research, scientists have experimentally demonstrated the advantages that graphene may have over copper for interconnects in future generations of integrated circuits. Researchers at the Georgia Institute of Technology, US, report detailed analysis of resistivity in graphene nanoribbon interconnects as narrow as 18 nanometers.

April 23rd, 2009 WASHINGTON - Scientists from University of California, Davis have developed an ultra small chip that provides breakthrough speeds for a variety of computing tasks. The 167-processor chip, known as AsAP, is fully reprogrammable, extremely energy-efficient, highly configurable.

April 17th, 2009 WASHINGTON - Scientists have studied alligators to analyze what life may have been like for dinosaurs at low oxygen levels of 12 percent during pre-historic times. The scientists chose the alligator as a test subject for the study because they are believed to be the modern relatives of the dinosaurs.

April 8th, 2009 WASHINGTON - Scientists at the University of Liverpool, UK, have discovered a five-sided ice chain structure that could be used to form clouds in the atmosphere and modify future weather patterns. Researchers, in collaboration with University College London and the Fritz-Haber Institut in Berlin, created the first moments of water condensing on matter - a process vital for the formation of clouds in the atmosphere - by analysing how the two interact on a flat copper surface.

April 7th, 2009 WASHINGTON - Bank cards may now be protected against fraud, thanks to a near-field scanner that can accurately detect weak fields. The development of this scanner is a result of the joint efforts made by researchers from the Fraunhofer Research Institution for Electronic Nano Systems ENAS in Paderborn and Continental and Infineon Technologies.
