Germs Taken to Space Come Back Stronger and Deadlier

The germ Salmonella was put on a space shuttle and sent into space because scientists wanted to see how space travel has an affect on germs. Researchers found that 167 genes had changed in the salmonella that went into space. They say that the germs change genetically because they sensed that they were in new environment. When they fed mice the germs from space they were three times more likely to get sick and die than the mice that were fed germs that didn’t go into space.

Doctors Create Schizophrenic Mice

It is reported that scientists have created the world’s first schizophrenic mice so that they could have a better understanding of the illness and be able to develop treatments. The mice were created by modifying their DNA to mimic a mutant gene first found in a Scottish family with a high incidence of schizophrenia. The egg cells of mice were genetically changed by injecting a gene associated with schizophrenia into their DNA. The eggs were fertilized and grown into baby mice using surrogate mothers.

The mice’s brains were found to have features similar to humans with schizophrenia, such as depression and hyperactivity.
