Astrobiologists are focused on resolving two central questions to understand the environmental and chemical limits of life. By understanding life's boundaries, they intend to identify possible biosignatures in exoplanet atmospheres ...
Nanoparticles can be used as substrates for computation, with algorithmic and autonomous control of their unique properties. However, scalable architecture to form nanoparticle-based computing systems is lacking at present. ...
(Phys.org)—Neurons might not be able to send signals as fast as electrons in wires or photons in fiber, but what if they can communicate using miniature sonic booms? That would be quite a revolutionary discovery. A group ...
(Phys.org) —Defining the essential character of the action potential of neurons has proven to be an elusive task. As typically happens, the biggest advances seem to have been made early on. In this case it was Hodgkin and ...
Membrane separations have become critical to human existence, with no better example than water purification. As water scarcity becomes more common and communities start running out of cheap available water, they need to ...
