Glucose derived redox equivalents preserve PKA activity and glucagon secretion during hypoglycaemia

The release of glucagon from pancreatic alpha cells is a core component of hypoglycaemic counter regulation. Several mechanisms regulate glucagon release including paracrine control by neighbouring cell types, and changes in extracellular glucose. While the inhibitory effect of glucose on glucagon secretion is well established, the exact way in which glucose metabolism contributes to alpha cell…

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.
