• Resumen

  • This report from Nature summarizes two breakthroughs in "green" chemistry: A rechargeable Mg battery that might one day become an environmentally benign replacement for our current car batteries, and new polymers that greatly improve the solvent properties of supercritical CO2. Another article highlighted in this column confirms that fresh apples contain oxygen radical scavengers that are more potent than pure vitamin C. Finally, DNA-fueled molecular tweezers are featured that take advantage of the specific interactions between complementary strands of DNA to bring about opening and closing of this nano-device.
