Melaninized fungi use ionizing radiation for energy

Blogging about Peer-Reviewed ResearchA recent paper in PLoS One entitled Ionizing Radiation Changes the Electronic Properties of Melanin and Enhances the Growth of Melanized Fungi describes some pretty amazing results that have gotten some press lately. The lead author, Dr Dadachova, spoke on NPR’s Science Friday last week about how melanized fungi are able to use ionizing radiation for energy as seen in the enhanced growth in their experiments.

While this is the first report of such as result, the fact that innovation occurs wherever there is free energy is not surprising. As mentioned by Arturo Casadevall this story in the spring when he was gave a seminar at Berkeley, marine organisms that live near undersea hydrothermal vents have been able to photosynthesize the infrared light emitted from the vent. He discussed the radiation utilization of melanized fungal work at the end of his talk, and said that it has been an epic process to get it published — that this work had been in review for four years at several high profile journals, but I guess that it was controversial enough to not be accepted there. I guess Nature and Science get it now since they wrote news briefs…
