Distinct extracellular matrix states uncouple collagen accumulation from pathological fibrosis in Duchenne muscular dystrophy

Fibrosis severity is routinely inferred from collagen abundance, although whether collagen quantity determines pathological fibrosis remains unclear. In Duchenne muscular dystrophy (DMD), chronic muscle injury and inflammation drive extracellular matrix accumulation, making these processes difficult to disentangle. We exploit sarcospan overexpression in mdx mice, a model of DMD (mdxTG), which…

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.
