While a couple of drinks is said to improve your memory, you still run the risk of damaging your liver due to excessive drinking (come on, who drinks just one mug anyway?).

British scientists from New Castle University developed a technique to create a "mini liver" the size of one pence piece. The Lilliputian liver will be further developed to create a full-sized and fully functioning liver. The mini liver came into existence when a tissue was created from blood taken from umbilical cords of babies a few minutes after birth.

At its current stage, the mini liver will be used to test new drugs and at the same time lower the number of animal experiments. That's hitting two birds with one stone mini liver.

In the long run, lab-grown livers could be used for liver transplants - a welcome news to hundreds of Britons who wait in line each year for a brand-spanking-new liver.

More than the excuse to engage in a drinking spree, the breakthrough will introduce a way to test new drugs. It could iron out difficulties before administering new drugs to humans. While UK Transplant welcomes the "Eureka moment", it still believes that the obvious way for people to help is by adding their names to the organ donor list.
