Measuring the bite force of tiny nematodes using nanoparticle technology
Microgauges allow simultaneous electrophysiology and opto-mechanical imaging of feeding forces in living C. elegans. Credit: Nature (2025). DOI: 10.1038/s41586-024-08331-x A team of materials scientists, physicists, mechanical engineers, and molecular physiologists at Stanford University has developed nanoparticle technology that can be used to measure the force dynamics inside living things, such as worms as they chew on their food. In a…

Scientists uncover insights into neuron function by measuring two key signals simultaneously in living animals
When triggered by odor, C. elegans olfactory neurons undergo rapid changes in membrane potential and intracellular calcium ion levels, leading to fluctuations in the fluorescence intensity of membrane potential sensors and calcium ion sensors. Researchers at Kyushu University measured these changes simultaneously using high-speed capture under a microscope and subsequent image processing, showing that the two signals encode different information…

Controlling light while measuring trapped ion qubits
AQM characterization scheme. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-50864-2 Quantum information is fragile and often difficult to protect during experiments. Protecting qubits from accidental measurements is essential for performing controlled quantum operations, especially when protocols such as quantum error correction involve measurements or resets that corrupt the state of neighboring qubits. Current methods for protecting atomic qubits from disturbances waste…
