Biotech Is The New Nanotech

Not only could we use algae as a new fuel source soon, but we also might use it to create better nanotechnology. Diatoms, tiny phytoplanktons, come encased in a unique cell wall made out of silica, which has pores and channels that increase its surface area dramatically. Using the existing complexity of these natural structures in nature could be a cheap way to make "lab-on-a-chip" systems for micro-analysis... without any industrial chemical processes.

Freakishly Huge Algae Bloom in London

Massive algae blooms killed seals, birds and sea lions on the California coast earlier this yea because algae exudes a toxin called domoic acid. When these blooms got out of control, aquatic animals would ingest the toxin because the fish they eat had been nibbling on these super-blooms. But those algae blooms were nothing compared to this one, seen in London's Hyde Park last year.

It's an art installation by Tony Heywood, called Super Algal Bloom. Covered in jewels, the algae is inspired by microscopic pictures of the same kinds of algae that killed seals in California. Don't worry - no animals were harmed in the making of this freaky macro-micro scientific art. Photo by CARL DE SOUZA/AFP/Getty Images.
