(Phys.org)—A new study by a team of chemists in Greece has added credence to a theory that suggests that humans differentiate smells by sensing molecular vibrations, rather than through simple binding to receptors. In their ...
(Phys.org)—An international team of scientists has taken the next step in creating nanoscale machines by designing a multi-component molecular motor that can be moved clockwise and counterclockwise.
