Knowing me, knowing flu
Why are some people more vulnerable to flu than others? Sarah Smith, a PhD student at the Wellcome Trust Sanger Institute, describes one reason why in her shortlisted article for the Max Perutz Science Writing Award 2012.
You’re 100 feet below sea level, crammed onto a London tube full of commuters, all breathing in the same stale air. The tickle in your nose is becoming too hard to ignore, but where’s a tissue when you need it? Aaaachhhhhhooo! Oops. You just sent 20,000 salivary droplets hurtling across the carriage. If you’re infected with influenza there could be thousands of viral particles in that sneeze. If everyone in your carriage inhaled a few of these particles, the outcome could be dramatically different for each person. Why? That is where my research matters.

A gene is a sequence of DNA nucleotides (A, T, G or C) that provides the instructions for a cell or virus to assemble a protein, the bricks and mortar of the cell. Read more
