there is boron on mars — another sign the red planet could have hosted life

nasa's mars rover curiosity has discovered boron in gale crater — new evidence that the red planet may have been able to support life on its surface in the ancient past. boron is a very interesting element to astrobiologists; on earth, it's thought to stabilize the sugary molecule ribose. ribose is a key component of ribonucleic acid (rna), a molecule that's present in all living cells and drives metabolic processes. but ribose is notoriously unstable, and to form rna, it is thought that boron is required to stabilize it. when dissolved in water, boron becomes borate, which, in turn, reacts with ribose, making rna possible. [boron found on mars for first time by curiosity (video)] in a new study published in the journal geophysical research letters, researchers analyzed data gathered by curiosity's chemcam (chemistry and camera) instrument, which zaps rocks with a powerful laser to see what minerals they contain. chemcam detected the chemical fingerprint of boron in calcium-sulfate mineral veins that have been found zigzagging their way through bedrock in gale crater, the 96-mile-wide (154 kilometers) crater that the rover is exploring. these veins were formed by the presence of ancient groundwater, meaning the water contained borate. the find raises exciting possibilities, the researchers said. "because borates may play an important role in making rna — one of the building blocks of life — finding boron on mars further opens the possibility t...
