Los Alamos’s magnetic algae project so far successful
In New Mexico, Los Alamos National Laboratory researched have genetically engineered “magnetic” algae to investigate alternative, more efficient harvesting and lipid extraction methods for biofuels. Researchers took a gene that is known to form magnetic nanoparticles in magnetotactic bacteria and expressed it in green algae, where a permanent magnet can be used to separate the transformed algae from a solution.
