Now that's a vending machine!

Shoppers in Germany will soon be able to buy gold as easily as bars of chocolate after a firm announced plans to install vending machines selling the precious metal across the country.

TG-Gold-Super-Markt aims to introduce the machines at 500 locations including train stations and airports in Germany. The company, based near Stuttgart, hopes to tap into the increasing interest in buying gold following disillusionment in other investments due to the economic downturn.

Gold prices from the machines – about 30 per cent higher than market prices for the cheapest product – will be updated every few minutes. Customers using a prototype "Gold to go" machine at Frankfurt Airport on Tuesday had the choice of purchasing a 1g wafer of gold for €30, a 10g bar for €245, or gold coins. A camera on the machine monitors transactions for money laundering controls.

Thomas Geissler, who owns the company behind the idea, said: "German investors have always preferred to hold a lot of personal wealth in gold, for historical reasons. They have twice lost everything. "Gold is a good thing to have in your pocket in uncertain times."

Entrepreneurs' brains are different

Scientists at Cambridge University have found that entrepreneurs’ brains work differently. Research published this month in Nature Magazine found entrepreneurs' brains are more active in the region responsible for making snappy decisions. These entrepreneurial traits have been linked to the release of dopamine in the brain: the same chemical that swamps your system when you eat chocolate or listen to music. Drugs could be developed to enhance entrepreneurial traits by mimicking these reactions. According to Barbara Sahakian, who headed up the research, entrepreneurs had more developed “medial and orbital sectors of the prefrontal cortex”. But she added that the mental processes required to take greater risks could be taught, or enhanced with drugs.
