Boron Detected on Mars Could Have Once Supported Life

UNITED NEWS INTERNATIONAL (UNI) — Scientists say they’ve found a clue that Mars might have once supported life.

According to a new report published in the journal Geophysical Research Letters, NASA’s Curiosity rover detected traces of the chemical element boron.

When dissolved in water, boron helps form ribonucleic acid, or RNA, which is a part of every living thing. Some scientists think RNA is the very first starting point of life as it decodes and expresses genes from DNA.

Study author Patrick Gasda said, “Without RNA, you have no life… The presence of boron tells us that … these chemical reactions could have occurred.”

This is the second time boron has been linked to the Red Planet. A Martian meteorite with traces of boron was found in Antarctica four years ago.

Some say the discovery supports the theory that life started on Mars and was carried to Earth on an asteroid.
