Why in news
Researchers at the Indian Institute of Science (IISc) discovered that perchlorate, a toxic chemical in Martian soil, promotes the formation of stronger bricks by stressed bacteria.
Background
The study, published in PLOS One, used a native bacterial strain from Bengaluru soil to build space bricks from synthetic Martian or lunar soil. The bacteria produce more proteins and calcium chloride-like precipitates when exposed to perchlorate.
