Scientists Debate Arsenic-Based Life Discovery
Reading
Scientists found tiny things in a lake. These things were bacteria that used arsenic to grow. Arsenic is bad for most living things on Earth.
This discovery made people very excited and curious. If true, life could exist in new places. It might even mean life is possible on other planets too.
Other scientists tried to do the same experiment. They could not get the same results. Some think the first experiment had small errors in it.
The journal \"Science\" took back the research paper. They did this because the results were not correct. The journal did not think the scientists cheated or did anything wrong.
The scientists who did the work disagree with the journal. They still believe their data is good. They think it is normal to argue about science findings.
