In a quest to understand how the body detects sour taste, the researchers found a proton channel involved in the body’s ability to maintain balance. Scientists at the USC Dornsife College of Letters, Arts and Sciences have discovered an entirely new class of ion channels. These channels let protons (H+ ions) into cells, are important in the inner ear for balance, and are present in the taste cells that respond to sour flavors.

Protons control whether a solution is acidic or basic. They set pH...

Blue Waters numerical relativity simulation of two colliding black holes with the open source, numerical relativity software, the Einstein Toolkit. Authors: R. Haas and E. Huerta (NCSA/University of Illinois); Visualization: R. Haas.

Scientists at the National Center for Supercomputing Applications (NCSA), at the University of Illinois at Urbana-Champaign, have pioneered the use of GPU-accelerated deep learning for rapid detection and characterization of gravitational waves. This new approach will enable astronomers to study gravitational waves using minimal computational resources, reducing time to discovery and increasing the scientific reach of gravitational wave astrophysics. This innovative research was recently published in Physics Letters B.

Combining deep learning algorithms, numer...

AKT isoforms have distinct hippocampal expression and roles in synaptic plasticity. eLife, 2018 DOI: 10.7554/eLife.30640.001

New study sheds light on key protein. For 5 years, the assistant professor of integrative physiology at CU Boulder has been working to better understand a protein called AKT, which is ubiquitous in brain tissue and instrumental in enabling the brain to adapt to new experiences and lay down new memories. Until now, scientists have known very little about what it does in the brain. But in a new paper funded by the National Institutes of Health, Hoeffer and his co-authors spell it out for the first time, showing that AKT comes in 3 distinct varieties residing in different kinds of brain cells and affecting brain health in very distinct ways...
