The week in physics: Threats to dark skies; Shaking suspensions; Lander resigns

Dark-sky advocates confront threats from above and below Forward this email  View in your browser THE WEEK IN PHYSICS: 7–11 FEBRUARY Webinar Live Webinar: Extreme sensitivity charge detection with lasers Although laser-induced avalanche breakdown of air was observed soon after the first demonstration of the laser, its ability to drive exponential charge growth has only recently been harnessed as an ultra-sensitive charge detection technique. I will describe our work making this possible. Register now. Solid sorbent captures carbon A new zinc metal–organic framework physically snatches carbon dioxide from wet gas, even in humid conditions. Alex Lopatka Dark-sky advocates confront threats from above and below Astronomers are working to reduce the impact on the night sky of artificial lighting and swarms of shiny satellites. Rachel Berkowitz FROM THE VAULT: February 1975 Crystallography and the future With synchrotron sources as well as new detectors, materials and techniques, this 60‐year‐old discipline continues to capture the interest of solid‐state physicists. André Guinier Science adviser Eric Lander resigns over verbal abuse of staff The US's top science official submitted his resignation after subordinates went public with their complaints that he had created an atmosphere of intimidation. William Thomas Webinar Live Webinar: Spectroscopy of color centers in silicon Color centers in Silicon are emerging as quantum information systems operating at telecom wavelength, compatible with large scale fabrication methods and fiber optic networks. The webinar will explain their fabrication, properties and technologies for spectral characterization. Register now. How vibrating a dense suspension prevents it from jamming Intuitively, you'd expect shaking a thick slurry stuck in a pipe could free it. But what's the physics behind the process? Charles Day New books: February 2022 A listing of newly published books spanning several genres of the physical sciences. Webinar Live Webinar: Deterministic single-photon sources for photonic quantum technology Photonics offers a scalable approach to the most daring quantum applications: quantum computers or the quantum internet. The webinar describes deterministic photon source for the generation of high-quality single-photon and multi-photon entanglement and the roadmap to applications. Register now. FROM THE FEBRUARY MAGAZINE Astrochemistry in the terahertz gap New capabilities are enabling laboratory spectroscopists to acquire more molecular spectra that advance our chemical understanding of the universe.
