Center for Physiology and Biophysics: News of the Day
  1. Flies smell through a Gore-Tex system
    Scientists have gained important insights into how the nanopores that allow the fruit fly to detect chemicals in the air, and has identified the gene responsible for their development.

  2. Cell-killing proteins suppress listeria without killing cells
    New research shows that key proteins known for their ability to prevent viral infections by inducing cell death can also block certain bacterial infections without triggering the death of the host cells.

  3. Making a fast ion transporter
    An international team of researchers reveals an ion transport mechanism of sodium/proton antiporter by simulating its motion. Based on the simulations, they now design a faster transporter by making mutation on ''gate'' of the transporter.

  4. New deep-learning approach predicts protein structure from amino acid sequence
    A scientist has used a form of artificial intelligence known as deep learning to predict the 3D structure of effectively any protein based on its amino acid sequence. This new approach for computationally determining protein structure achieves accuracy comparable to current state-of-the-art methods but at speeds upward of a million times faster.

  5. Bacteria harness viruses to distinguish friend from foe
    Bacterial cells that normally colonize our guts can distinguish themselves from other bacterial species using what's traditionally considered their enemy -- a virus. Researchers report that some bacteria use viruses that have infected them (i.e., phages) for self-recognition and thereby show greater fitness, repelling competitors that lack this adaptation.

  6. Of quirky channels and a fond farewell

    This final installment of Generally Physiological concerns F-selective channels, a surprising role for a tryptophan in determining channel identity, and a farewell note from the Executive Editor of The Journal of General Physiology.

(a) Bordetella pertussis...
