The field of brain-machine interfaces has made great leaps in its understanding of the brain, how its codes and interprets information and how to use that knowledge to "connect" brains and machines.

In this article, David Schwarz, graduate student in the Nicolelis Lab at Duke, one of the world leaders in brain-machine interfaces, explains some recent advances in the field, what they mean and the road ahead.

In this article, part of our collaboration with El Nuevo Día, Wilson González Espada explains what happens when technology jumps ahead of science and launches products that have not been tested for safety. Some examples include X-rays, the pigment green of Paris, radioactive materials sold as energy boosters and recently, some pain medications that ended up having adverse cardiovascular effects.
