Researchers uncover potential biosignatures on Mars

A new study has revealed chemical signatures of ancient Martian microbial life in the Bright Angel formation, a region of Jezero Crater known for its fine-grained mudstones rich in oxidized iron and organic carbon. The findings suggest that early microorganisms may have played a role in shaping these rocks through redox reactions.

Tip tricks control reactions in a single molecule

Scientists have developed a method to control chemical reactions in a single molecule by applying voltage pulses, resulting in unprecedented selectivity. By fine-tuning the voltage, researchers can interconvert different products formed during the reaction.

Switched-on DNA

An ASU-led team has developed the first controllable DNA switch, allowing for reversible control of electricity flow within a single molecule. The modified DNA helix can conduct electricity and is reversibly controlled using an anthraquinone group.

How solvent molecules cooperate in reactions

Researchers discovered that solvent molecules can significantly impact the formation of an ether molecule, even when they don't directly participate in the reaction. A second methanol molecule is essential for the reaction to occur, indicating that solvent molecules are not just bystanders but rather assistants.

Pushing a single-molecule switch

Researchers activate a single molecule switch using an atomic-force probe, revealing the need for precise positioning and chemical reactivity. The study's findings could lead to new control of chemistry at the atomic level.
