But originally, much of the med
2、icine developed in the last century came from natural sources: plants or bacteria. Now, a group of scientists in Great Britain are hoping to develop a medicine from poisonous insects. They are researching whether the deadly venom（毒液）of some insects can work against bacteria.Venom tech laboratoryAbou
3、t 400 insects live in plastic containers in the Venomtech laboratory. Each container has an image of a skull and crossbones. The images warn that a bite from the insects inside can be anything from painful to deadly.The venom from these insects contains hundreds of chemical components. Each componen
4、t has a different target and effect. Medical researchers separate the venom into its component parts. Then they create a library of those components, looking for the ones that could be turned into new drugs. “Some of them we found can kill bacteria, like E Coli, so theyre very relevant at the moment
5、 where modern medicines are failing. And were also finding venom that is changing and killing cancer cells.”Finding new ways to kill bacteria is important to researchers. One reason is that people have used antibiotics (抗生素)so much that some bacteria can now resist it. For example, tuberculosis used
6、 to be curable with antibiotics. Now it is not. How do they get the venom out? To get as much venom as possible, researchers feed the insects well and then put them to sleep temporarily.

Researchers separate the venom into hundreds of proteins. Each protein contains between one and five different molecule

So far，the trackers show that he swam nor
