This Week in Physics — The Cost of Sending a Bit Across a Living Cell

This Week in Physics Magazine — August 7, 2023 Viewpoint The Cost of Sending a Bit Across a Living Cell Artemy Kolchinsky – August 7, 2023 Calculations of the minimum energy a cell requires to transmit a signal between two internal components could help scientists understand how energy and information combine to produce living systems. synopsis Record-Breaking Detection of Solar Photons August 3, 2023 Measurements of the highest-energy radiation from the Sun ever seen highlight the need for better solar models. Research News Self-Healing Metal Observed August 3, 2023 Researchers observe a metal with self-healing nanocracks, which form when the material is subjected to a force and then retreat. Focus Radar Resolution Gets a Boost August 2, 2023 A low-frequency radar method with improved resolution could aid in the detection of landmines and archeological objects. synopsis Standard Model Stays Strong for Leptons August 2, 2023 New data from observations of B-meson decay again vindicate the standard model of particle physics. Video Magnetic Microdisks Don't Always Reciprocate August 4, 2023 A model system of floating disks can be tuned to execute a variety of behaviors by controlling the interactions between the disks. synopsis Knotted Networks Form Cellular Safety Nets August 4, 2023 Simulations show that the topology of biopolymer "tangles" controls how biological cells resist deformation. synopsis Watching a Quantum System Thermalize August 1, 2023 Atoms trapped in a one-dimensional optical lattice can mimic how—in a basic quantum field theory—massive particles reach, or fail to reach, thermal equilibrium. 1 Physics Ellipse, College Park, MD 20740 © 2023 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.
