    Tea: the nation’s favourite beverage and a drink synonymous with British culture.

    As one of the 40 million Britons who enjoy a cup a day, “Science of Tea” immediately caught my eye in the festival programme – ‘an evening dedicated to the chemistry and pharmacology behind the nation’s favourite beverage’ – what better way to spend a Friday night in Cheltenham?

    1992, was the year it hit me! As I entered the brave new world of primary education, I remember being startled with the knowledge that we lived on a ball of rock, travelling some 67,000 miles per hour around a massive burning ball of fire. Naturally, this was a pretty terrifying turn of events!

    As the shock subsided, and my terror turned to awe, I was told that the Earth was one of a small group of planets orbiting our local star.

    There was more.

    I usually succumb to three bouts of the common cold a year – once over Christmas, once during exams and the final wild-card infection usually manages to time itself to ruin a holiday.

    Is that normal? Hundreds of people who wanted to know the answer attended an event at The Times Cheltenham Science Festival. Vivienne Parry, host of BBC Radio 4’s Am I Normal?, chaired a panel of researchers who investigate immunity.

    Imagine, suggested Professor Arne Akbar (UCL Division of Infection and Immunity), that you are a pork chop left out in the sun. You might just smell a little on the first day. But over the course of a few days, you would begin to stink and turn to mush as your tissue broke down.

    Regenerative medicine: is the grow-your-own organ era just around the corner?

    What happens if a newt’s leg is cut off? Or a gecko’s tail auto-amputated?

    The cells simply multiply to grow back into exactly what was missing. If a flatworm were cut in two, the two halves would both become new flatworms.

    Unfortunately for humans, this incredible ability to self-regenerate was lost several branches ago on the evolutionary tree. As such, we definitely don’t have the ability to grow a new leg, or a new heart.

    We have to rely on skin grafts and organ transplants, with common risks of rejection, infection and multiple complications. However, according to Professor Mark Birchall and Dr Felicity Mehendale, our regenerative future is just around the corner.
