Large-scale supercomputer simulations at the atomic level show that the dominant G form variant of the COVID-19-causing virus is more infectious partly because of its greater ability to readily bind to its target host receptor in the body, compared to other variants.

Professor Junsuk Rho's research team at POSTECH develops wearable gas sensors that display instantaneous visual holographic alarm.

South Korea's Ulsan National Institute of Science and Technology (UNIST) has proposed a satellite-aided drought monitoring method that can adequately represent the complex drought conditions into a single integrated drought index.

What are the most effective ways to leverage and augment smartphone capabilities? Helpful guidelines are provided in a critical review of emerging smartphone-based imaging systems recently published in the Journal of Biomedical Optics (JBO).

University of California Berkeley researchers initiated a collaboration that gathered engineers from different universities worldwide to create a photonic MEMS switch using a commercially available complementary metal-oxide-semiconductor (CMOS) fabrication process without modification. The use of this well-known microfabrication platform represents a huge step toward industrialization because it is compatible with most current technologies, cost-effective, and suited for high-volume production.

New research in Science Advances provides template for developing directly-acting antivirals with novel modes of action, that would combat COVID-19 by suppressing the SARS-CoV-2 viral infection. The study focused on the macrodomain part of the Nsp3 gene product that SARS-CoV-2 uses to suppress the host cell's natural antiviral response. Viruses that lack it cannot replicate in human cells, suggesting that blocking it with a drug would have the same effect.
