"Very Unreal and Fantastic": Electric Cables Created by Bacteria
November 10, 2012
Researchers discovered bacteria at the ocean floor that conduct electrons at distances more than a centimeter through elaborate cables.
Mighty Mitochondria Conduct Energy Exquisitely
October 7, 2011
None of us could live without mitochondria. These are the power centers ubiquitous in eukaryotic cells. They contain molecular machines in factories whose jobs are to generate and conduct electrical currents. The currents run turbines that packetize the energy in molecules of ATP, which are then used by most processes in the cell. New discoveries continue to fascinate scientists with how mitochondria work. Some scientists use their energy to find ways Darwinian evolution could build the machinery of life.
Rubisco “Highly Tuned” for Fixing Atmospheric Carbon
June 22, 2006
Rubisco sounds like a brand of cracker or something, but it’s actually an air cleaner your life depends on. It’s an enzyme that fixes atmospheric carbon for use by photosynthetic microbes and plants. In doing so, it sweeps the planet of excess carbon dioxide – the greenhouse gas implicated in discussions of global warming – […]
