Two young scientists break down plastics with bacteria

Once it's created, plastic (almost) never dies. While in 12th grade Miranda Wang and Jeanny Yao went in search of a new bacteria to biodegrade plastic -- specifically by breaking down phthalates, a harmful plasticizer. They found an answer surprisingly close to home.

Programming bacteria to detect cancer (and maybe treat it)

Liver cancer is one of the most difficult cancers to detect, but synthetic biologist Tal Danino had a left-field thought: What if we could create a probiotic, edible bacteria that was "programmed" to find liver tumors? His insight exploits something we're just beginning to understand about bacteria: their power of quorum sensing, or doing something together once they

What will humans look like in 100 years?

We can evolve bacteria, plants and animals — futurist Juan Enriquez asks: Is it ethical to evolve the human body? In a visionary talk that ranges from medieval prosthetics to present day neuroengineering and genetics, Enriquez sorts out the ethics associated with evolving humans and imagines the ways we'll have to transform our own bodies if we hope to explore and
