Our job is to ensure that the truth is heard. We must remind the world that every mouse in every lab is real and individual, and that when they call out for an end to their suffering, at a sonic pitch researchers are deaf to, their cry is as meaningful as anything a richly-plumaged bird on the wing can muster.
In a bid to mimic the effects of Parkinson's disease, a London medical research team injected 22 marmoset monkeys with a potent brain poison every day for five days. After the last dose, none was able to move. They sat hunched, mute and rigid in their cages, so severely disabled that they had to be hand-fed. The monkeys were then given the illegal party drug Ecstasy in the hope that it might provide insights into chemical pathways within the brain. None of this research proved beneficial to humans; rendering the suffering of the monkeys valueless. This experiment was part funded by the medical charity Parkinson's UK.
This weekend, millions of Brits will be betting on one of the world's most spectacular sporting events. The Grand National will be watched by about ten million viewers in this country alone - once a year punters will be placing a bet and people who don't normally watch horse racing will be watching the big race.
