Research agencies have ordered UK scientists to improve the way they use animals in experiments. The organisations have warned that too often poorly designed projects testing new medicine for strokes, cancer and other conditions have produced meaningless results while wasting animals’ lives. In some cases, researchers have undervalued the importance of the number of animals needed to test a new medicine in an effort to control the costs of their study. As a consequence, their small scale studies have lacked the power to identify biological effects in the drugs under investigation.
These unreliable results mean that the lives of the animals involved have been wasted, along with scientists’ time and resources. In other words, the overuse of animals in experiments has led to unnecessary as well as pointless loss of their lives.
The problem of poorly designed studies has been under investigation for two years and culminated last week when the Research Councils announced changes to guidelines for those carrying out research using animals. Scientists will now have to show that their work will produce physiological insights as well as generate statistically valid data; otherwise they will lose their funding.
A neuroscientist of Edinburgh University pinpointed that these guidelines should be welcomed by the scientific community, although it has taken a long time to introduce them, adding that there has been an increasing awareness that the results of some animal experiments are not in fact very strong.
