Mutations in SARS-CoV-2 Nsp1 are critical determinants of viral pathogenicity in mice

Severe Acute Respiratory Coronavirus 2 (SARS-CoV-2) nonstructural protein 1 (Nsp1) dampens the host immune response by shutting off host gene expression, a strategy that has remained evolutionary conserved among a diverse range of coronaviruses (CoVs). Residues important for SARS-CoV-2 Nsp1 mediated host shutoff have been incompletely defined. We have generated and characterized the ability of…

Flightless beetles evolved distinct snail-hunting shapes on Japan's largest island

Islands are widely recognized as natural laboratories of evolution. The ocean restricts movement among islands, allowing isolated populations to adapt to different environments and, at times, diverge into new species.

Scientists map the microscopic roots of chaos in dusty plasma using supercomputer simulations

Research Matters Staff Writer(s) Jammu 17 Aug 2026 Researchers have achieved a breakthrough in understanding the chaotic world of turbulence by tracking the movement of millions of individual particles in a specialised state of matter known as dusty plasma.

Scientists map microscopic origins of turbulence in dusty plasma using supercomputer simulations.
Understanding dusty plasma turbulence could improve plasma containment in nuclear fusion reactors.
