Wi-Fi Proof Security Paint | DevicePedia.com

Are you concerned about the neighbours stealing your bandwidth? Maybe if you buy things online or access your bank account you are worried about security. Well fear not because researchers have developed an unlikely sounding way of protecting your Wi-Fi. They have developed a special kind of paint which contains an aluminium and iron oxide capable of absorbing radio waves, which includes Wi-Fi. The paint has been developed by the University of Tokyo and they claim it won’t be especially expensive.

By using the paint you are effectively shielding the walls with magnetic particles and so you could also block electromagnetic radiation from outside. Apparently paints blocking lower frequencies have been available for a while but this is the first to block up to 100 GHz and researchers are working on a paint that can absorb over 200 GHz. One of the best potential uses for this would be to coat the inside of movie theaters and prevent mobile phone signals from getting through.

G-7 Avoids Dollar Criticism, Warns Against Volatility

03.10.09

By Simon Kennedy and Mark Deen

Oct. 3 (Bloomberg) -- Group of Seven finance chiefs stopped short of singling out the weaker dollar for criticism and stuck to their mantra that “disorderly” swings in currencies threaten economic growth.

“Excess volatility and disorderly movements in exchange rates have adverse implications for economic and financial stability,” G-7 ministers and central bankers said in a statement after talks today in Istanbul. Officials welcomed China’s “continued commitment” to a more flexible currency, which they said would promote balanced global growth. The statement repeated language used at the last G-7 in April.

The group met at the end of a week in which policy makers from France to Canada signaled concern that a sliding dollar risks impeding their recoveries from the deepest global recession since World War II. The dollar has dropped 14 percent against a basket of seven currencies since early March.

“Following the escalated rhetoric, investors may have been braced for some escalation in language,” said Sophia Drossos , co-head for global foreign exchange strategy at Morgan Stanley in New York. “Since we didn’t get it, I look for the trend of dollar weakness to reassert itself.”
