This Week in Physics - Shining Light on Electron Microscopy

This Week in Physics Magazine — September 26, 2022 Viewpoint Shining Light on Electron Microscopy Herman Batelaan – September 26, 2022 A new method that uses laser light to both generate and shape electron beams could improve the resolution of electron microscopy. Research News Countdown to DART Impact September 20, 2022 In a first-of-its-kind test for planetary defense, NASA's DART spacecraft is scheduled next week to crash into an asteroid and alter the celestial body's course. Focus How Cells Move through Narrow Spaces September 20, 2022 Experiments demonstrate that biological cells actively change shape to respond to their surroundings when moving in confined regions. Focus Optimizing Flow Speed is Essential for the Gut September 23, 2022 Fluid dynamics simulations suggest that the varying flow speed inside the small intestine maximizes nutrient absorption while minimizing excess bacteria. Research News Plant-Based Strategy for Harvesting Light September 21, 2022 A new photodetector design borrows its light-gathering architecture from plants, offering a potential path to more efficient solar cells. synopsis Disordered Systems Mimic Genetic Evolution September 20, 2022 A bacterial genome's evolution under changing drug concentrations displays effects of memory formation and mimics how disordered solids respond to external forces. synopsis Information as Thermodynamic Fuel September 21, 2022 A "filtering" algorithm allows information engines to perform efficiently even when they are subjected to high noise. synopsis New Qubit Enters the Quantum-Computer Arena September 22, 2022 A new type of superconducting qubit could solve a "crowding" problem that hinders the development of superconducting quantum computers with large numbers of qubits. synopsis Wind Farms Perform Under Pressure September 23, 2022 Simulations show that negative wind shear can reduce the power output of wind farms. 1 Physics Ellipse, College Park, MD 20740 © 2022 American Physical Society | All rights reserved View Email Online You are receiving this message because you signed up to receive Physics Magazine email alerts or are a member of APS.
