HIV Protein Switch May Help Virus Squeeze into Host Cell Nucleus

HIV Protein Switch May Help Virus Squeeze into Host Cell Nucleus

by Ken Chiacchia | Feb 21, 2025 | Bridges-2, Science Highlights

The pointed end of HIV’s outer viral shell, its capsid, helps it squeeze into host cells’ nuclear pore. A team from Pitt has simulated the virus in PSC’s Bridges-2 to show how a twist in a critical protein may help it shoehorn in. Based on a figure from Yang DT et al....
Large-Scale Evolution Simulations on PSC’s Neocortex Tackle Questions about Hypermutator Evolution

Large-Scale Evolution Simulations on PSC’s Neocortex Tackle Questions about Hypermutator Evolution

by Ken Chiacchia | Feb 5, 2025 | Neocortex, Science Highlights

In real life, mutants can arise when their DNA changes to give them an advantage over the rest of the population. A team from the University of Michigan used simulations on PSC’s Neocortex to find out why beneficial mutants rarely come to dominate real...

Penn State Team Uses AI to Predict Dozens of Undiscovered Metal Nanoparticles

Penn State Team Uses AI to Predict Dozens of Undiscovered Metal Nanoparticles

by Ken Chiacchia | Nov 25, 2024 | Bridges-2, Science Highlights

Certain numbers of metal atoms can assemble into stable nanoparticles with symmetrical, crystalline shapes. Even more interesting are the irregular or unstable shapes that arise with the numbers in between. Adobe Stock 261656757 New Structures, Simulated and Studied...
