question 18: what's the smallest thing we can possibly build?

Scientists have a new box of toys. With new 'spectacles' and precision instruments they can not only see into the smallest of things but can also alter what they see. They can build molecules that didn't exist before, change ones that need improving. What does design at molecular level – nanotechnology – actually imply?  Read more

question 22: who cares about species death?

The finest source of inspiration for the pharmaceuticals industry is neither costly chemistry laboratories nor scientific journals. It's actually Nature herself, in particular the wealth of species in the tropics, that gives scientists ideas for medicines and treatments.  Read more

question 30: can we become our own doctors?

A simple saliva test at home in the morning and you can decide for yourself whether you need antibiotics. An implanted sensor that keeps a check on your blood sugar and fats. One day we'll be amazed at how little we used to know about what goes on inside us.  Read more

question 31: can stem cells cure Parkinson's disease?

What did the late Pope John Paul II have in common with former world boxing champion Mohammed Ali and actor Michel J Fox? Answer: Parkinson's disease. New stem cell research is giving the sufferers hope – but when will they get a treatment that works?  Read more

question 33: are you keeping up with your nano clock?

The nano clock – sounds like science fiction? In fact, both you and I have always been controlled by nano clocks. The world's smallest clock is actually also the world's oldest. All organisms that depend on sunlight also need something to measure time...  Read more
