Washington - With the US and global economy in turmoil, it was the trials and tribulations of a budding small business owner, "Joe the plumber," that took centre stage in the final debate between US presidential candidates Barack Obama and John McCain.
Battling for the vote of ordinary middle-class Americans just three weeks before the general election, both candidates apparently decided the economic woes facing the country were embodied in Joe Wurzelbacher, a man who made an appearance at an Obama election rally in Ohio.
Joe, who was first raised in Wednesday night's debate by McCain, had complained at the rally that he could not afford to buy his own plumbing business because of Obama's plan to tax wealthy Americans.
Washington, Oct 16 : Using surface-enhanced Raman spectroscopy (SERS), scientists have now demonstrated that gold and silver nanostars are more effective than commonly used nanorods and nanospheres for chemical and biological sensing and imaging.
The National Institute of Standards and Technology (NIST) researchers found that gold and silver nanostars improved the sensitivity of SERS 10 to 100,000 times that of other commonly used nanoparticles.
The uniquely shaped nanoparticles exhibit optical qualities that enable them to be used in a range of applications from disease diagnostics to contraband identification.
Washington - US presidential candidates Barack Obama and John McCain clashed on free trade and its value to a sputtering US economy during their last television debate of the election campaign.
Republican nominee McCain said Wednesday that opening up trade would foster millions of jobs in the United States but acknowledged that re-education programmes for US workers losing their jobs would have to be improved.

Washington, Oct 16 : Albert Einstein''s theory of relativity has survived a neutrino test, which was conducted by physicists trying to disprove the premise.
The physicists were working to disprove "Lorentz invariance" - Einstein''s prediction that matter and massless particles will behave the same no matter how they''re turned or how fast they go.
The test of Lorentz invariance, conducted by MINOS Experiment scientists, started with a stream of muon neutrinos produced at Fermilab particle accelerator, near Chicago, and ended with a neutrino detector 750 meters away and 103 meters below ground.
As the Earth does its daily rotation, the neutrino beam rotates too.
