The molecule-sized devices activated the same calcium-based cellular signaling mechanism in a live organism, causing whole-body contraction in a fresh-water polyp, or Hydra vulgaris. "This is the ...

Yale scientists have discovered a family of immune proteins, which they describe as a “massive molecular machine,” that could affect the way our bodies fight infection. Our immune system mobilizes ...

(Nanowerk News) One of the main ways cells “talk” to each other to coordinate essential biological activities such as muscle contraction, hormone release, neuronal firing, digestion and immune ...
