Researchers discover hidden SARS-CoV-2 'gate' that opens to allow COVID infection Posted: 19 Aug 2021 08:30 AM PDT Unprecedented visualizations of SARS-CoV-2 have allowed researchers to discover how the virus enters and infects healthy human cells. Supercomputing movies have revealed how glycans -- molecules that make up a sugary residue around the edges of the SARS-CoV-2 spike protein -- act as infection 'gates' that open to allow access to our cell's receptors. |
Home-grown semiconductors for faster, smaller electronics Posted: 19 Aug 2021 07:27 AM PDT 'Growing' electronic components directly onto a semiconductor block avoids messy, noisy oxidation scattering that slows and impedes electronic operation. A new study shows that the resulting high-mobility components are ideal candidates for high-frequency, ultra-small electronic devices, quantum dots, and for qubit applications in quantum computing. |
