Acoustic method could quickly catch counterfeit coins.
You might assume that counterfeiters only bother with high-value bank notes, but there is a chance that some of the coins jangling around in your pocket right now are fake. If Mototsugu Suzuki gets his way, it may be that jangling that gives them away.

Suzuki, a researcher at the Tokyo Metropolitan Police Department’s Criminal Investigation Laboratory in Japan, has developed a way of examining coins based on the sound they make.

The traditional method of spotting a fake coin is to look at it — very closely.

A study by Swiss scientists revealed that the flu virus can survive on banknotes for more than two weeks.

Yves Thomas, head of the National Influenza Research Centre at Geneva University Hospital was asked by a Swiss bank to carry out the study.

Scientists have long known that various types of germs and bacteria can survive on paper currency, but most medical experts had thought that the flu virus usually only spreads through airborne transmission. The new research revealed that certain strains of flu virus, especially the H3N2 variety, can remain active and alive for up to 17 days, as compared to the more benign H1N1 influenza A virus that lasts only a matter of hours.

“Our studies have convinced us that it is possible to catch flu from banknotes, but the chances are very, very slim and there is no cause for concern among the general population. All the same time , bank employees and others who have to handle large quantities of notes daily could be at risk” said Thomas. Continued

WITH THE DARK RECESSION CLOUDS SWEEPING across the newscape, gold is gaining more fans. Last week, it hit a record price of $904 an ounce before sliding back below $900.

Most investment pros agree that gold should constitute a sliver of any well-balanced portfolio — no more than 10% at any time. But how should you invest in the metal?

A recent study done by three finance professors and an executive at the Chartered Financial Analyst Institute in Virginia finds that the best way is not to hold bullion, or even to own the popular exchange-traded funds, such as the StreetTRACKS Gold Shares (ticker: GLD) or Central Gold Trust (GTU). No, sir. The best gold investments are those heavily fee-laden burros of Fundland, the gold-oriented funds. Read Full Story
