Washington, Sept 26 : Lying comes easy to office-goers when they use email for communication – even more so than the traditional pen-and-paper, suggests a pair of new studies.

According to the studies, workers have a tendency to lie more often in e-mail rather than in more traditional kinds of written communications, like pen-and-paper.

And surprisingly, the studies show that people actually feel justified when lying using e-mail.

Washington, September 26: Biologists at the Massachusetts General Hospital in Boston, U. S., have shown that it is possible to reprogram adult cells back to an embryonic state without using viruses that can leave dangerous copies of cancer-causing genes in the cells' chromosomes.

Research leader Konrad Hochedlinger has already done just that with adult mouse cells in his lab.

His work raises hope that the cells, known as "induced pluripotent stem cells" (iPS cells) can be made safe for transplantation into people.

The reprogramming technique was pioneered by Shinya Yamanaka of Kyoto University in Japan, who used retroviruses carrying four separate genes that effectively wipe the developmental slate of an adult cell.

United Nations, Sept 26: The US’ strikes on Pakistani soil were not eliminating terrorists, but actually serving to empower the forces against which Pakistan and America were fighting together, Pakistan President Asif Ali Zardari said in his UN address in New York last evening.

Washington, Sept 26 : Scientists at the University of California, Santa Barbara have created a new nanoscale process that will ultimately help make computers smaller, faster, and more efficient.

The scientists have for the first time devised a technology, called block co-polymer lithography, to make square, nanoscale, chemical patterns -- from the bottom up -- that may be used in the manufacture of integrated circuit chips as early as 2011.

Led by Craig Hawker, materials professor and director of the Materials Research Laboratory at UCSB, with professors Glenn Fredrickson and Edward J. Kramer, the researchers have developed a novel process for creating features on silicon wafers that are between five and 20 nanometers thick.

Washington, Sept. 26: Democratic presidential candidate Barack Obama and his party colleagues have blasted Republican rival John McCain for backing out of talks aimed at finding a solution to the current meltdown on Wall Street.

Aides and officials attending a White House Summit meeting here on Thursday said the discussion ended badly, with Democrats fuming at House Republicans over their refusal to drop objections to the administration’s 700 billion dollar bail out proposal.

Washington, September 26 : Researchers at Massachusetts Institute of Technology (MIT) have opened the door for significant improvements in the fuel efficiency of cars and aeroplanes by solving a century old engineering problem regarding how fluids—such as gasses and liquids—move. 

The researchers say that their new mathematical and experimental work can help predict where the airflow around a vehicle cannot keep up and will detach from it, a phenomenon scientifically known as aerodynamic separation.

Fluid flows affect everything in our world, from blood flow to geophysical convection, and, thus, engineers constantly seek ways of controlling separation in such flows to reduce losses and increase efficiency.
