'NanoPen' may revolutionise electronics sector, medical diagnostic testsSeptember 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.
Americans prefer taller presidential candidates in difficult times: StudyAugust 19th, 2009 LONDON - An American study conducted by social psychologists at Coastal Carolina University in Conway, South Carolina, suggests that the country's presidents get taller when the going gets tough. Lead researcher Terry Pettijohn looked at the heights, ages and facial attributes of the 11 elected US presidents over the past 75 years, and compared them with economic and social indicators such as unemployment and birth rates.
Monkeys, humans recognise faces the same wayJuly 13th, 2009 WASHINGTON - Rhesus monkeys and humans recognise faces the same way, according to the latest research. The study provides insight into the evolution of the critical human social skill of facial recognition, which enables us to form relationships and interact appropriately with others.
Soon, face recognition computers that can see through disguisesJuly 8th, 2009 WASHINGTON - Florida Atlantic University engineers in Boca Raton are working on a superior new face recognition technique that can see through disguises. Lin Huang, from the university's Department of Engineering, says that every face has special features that define people, yet faces can also be very similar.
New analytical technique to recognize archaeological material and fake masterpiecesJuly 2nd, 2009 WASHINGTON - Dutch researcher Laurens van der Maaten has developed a new analytical technique that enables the computer to recognize archaeological material and fake works of art. According to a report in www.physorg.com, the technique not only enables the computer to better interpret the content of photos and images, but also of data.
New technique to detect metabolites from a single drop of bloodJune 19th, 2009 WASHINGTON - A single drop of blood could soon be able to identify various blood related metabolites-such as sugars, fatty acids, amino acids and other organic substances-from plant or animal tissue samples. Scientists at the Max Planck Institute for Chemical Ecology in Jena and their colleagues from the Czech Academy of Sciences in Prague have developed a new method to quickly and reliably detect metabolites from only a drop of blood.
Detecting sulphur in just one hair could help nab a terroristMay 28th, 2009 WASHINGTON - In a new study, scientists have come up with a method that could be used to nab terrorists, by detecting how proportions of isotopes in a chemical like sulphur vary throughout the length of a single hair. The mid-term objective is to be able to use these methods to track the geographical movements of people, including international crime suspects and victims.
Scientists unveil simpler-to-manufacture 'broadband' cloaking technologyMay 21st, 2009 WASHINGTON - Purdue University researchers claim that they have created a new type of invisibility cloak that works for all colors of the visible spectrum, making it possible to cloak larger objects than before. Research leaders Vladimir Shalaev and Anne Burnett say that their new design may also pave the way for practical applications in "transformation optics"-such as the creation of "hyperlenses" for microscopes 10 times more powerful than those existing presently; computers and consumer electronics that use light instead of electronic signals to process information; advanced sensors; and more efficient solar collectors.
Jennifer Garner blames Ben Affleck for daughter's messy hairApril 18th, 2009 WASHINGTON - Hollywood actress Jennifer Garner has revealed that the person responsible for her daughter Violet's messy hair is her father Ben Affleck. Jennifer says that Ben is the one who takes Violet to school, and does her hair by simply tying to barrettes.
Simple process makes thin nanoribbons for conductive productsApril 16th, 2009 WASHINGTON - Scientists at Rice University, US, have uncovered a room-temperature chemical process that splits carbon nanotubes to make flat nanoribbons, which can be used to create basic elements for aircraft, flat-screen TVs, electronics and other conductive products. The technique makes it possible to produce the ultrathin ribbons in bulk quantities.
Overheating laptops may soon be historyApril 14th, 2009 WASHINGTON - Although laptops are getting smaller and easier to use day by day, they still get overheated causing circuits to melt and the hardware to fail. But, such problems may soon be history.
Scientists reveal new way to make narrower chip patternsApril 12th, 2009 WASHINGTON - An Indian-origin researchers at the Massachusetts Institute of Technology (MIT) has come up with a new way for etching extremely narrow lines on a microchip by exposing it to certain wavelengths of light. Research engineer Rajesh Menon and his colleagues call the new technique absorbance modulation.
Hidden exoplanet seen by scientist in Hubble's archivesApril 2nd, 2009 WASHINGTON - A scientist has identified an exoplanet that went undetected in Hubble images taken in 1998. The scientist, David Lafreniere of the University of Toronto, Ontario, Canada, detected the planet that was hidden in Hubble images taken with the telescope's Near Infrared Camera and Multi-Object Spectrometer (NICMOS) in 1998.
How to improve individual decision-makingMarch 12th, 2009 WASHINGTON - Researchers at the University of Basel have designed a new technique that could assist individual decision-making. Numerous studies have shown that a crowd of people usually gives more accurate responses to questions compared to a mere individual.
Not two months in job and Obama going greyMarch 6th, 2009 NEW YORK - The job is telling on Barack Obama. The 47-year-old president is going grey in less than two months in the White House.
