NewScientist 29.6. 2012 by Sara Reardon. IT IS the ultimate in subsea communications: bacteria living in sulphurous mud beneath the seabed respire by transforming themselves into long, insulating cables and shuttling electrons from one to another. This phenomenon has now been imaged for the first time, allowing us to see how some microbes pull off...

PhysOrg: As plants began to transition from aquatic habitats to dry land some 500 million years ago, their needs changed. Those primitive ancestors of modern plants were ill-equipped to survive in a dry, sunlight-blasted world. But gradually, they evolved enzymes that let them synthesize new kinds of chemicals to protect them from the threats of...
