The week in physics: Seagrass sounds; Non-line-of-sight cameras; Hidden water & earthquakes

Hidden water puts the brakes on earthquakes Forward this email  View in your browser THE WEEK IN PHYSICS: 9–13 AUGUST Advertisement Secure Transfer of Costly and Dangerous Gases KNF leak-tight pumps transport and evacuate costly, high purity, and dangerous gases. Featuring ultra-low leak rates of <6×10-6 mbar L/sec and a safety back-up diaphragm, plus safeguards to prevent intrusion contamination. Flow rates from 15 – 290 L/min. Options include inter-diaphragm monitoring, explosion-proof motors, and material choices. Learn more. The sound of seagrass In seawater, seagrass influences the speed of sound in a way that could serve as a diagnostic of ecosystem health. Charles Day Hidden water puts the brakes on earthquakes When extinct undersea volcanoes are shoved beneath adjacent tectonic plates, they can carry trapped seawater with them. Johanna L. Miller FROM THE VAULT: January 2015 Journalists debunk vaccine science denial Both before and after the Disneyland measles outbreak, most reporters have forthrightly exposed "anti-vaxxers." Steven T. Corneliussen Webinar LIVE WEBINAR: Superconducting circuits, Hamiltonian engineering of qubits and the Kerr-cat metapotential This webinar will discuss how the commercial availability of key technologies including robust cryogenic environments enable the exploration of quantum computation with circuits. We will focus on efforts performed at Yale on the so-called Kerr-cat qubit which presents clear advantages over similar superconducting qubits. Register now. Non-line-of-sight camera gets a resolution boost A pair of tightly synchronized and tuned lasers provide photons that are precisely detected at the picosecond scale. Alex Lopatka Behind the Cover: August 2021 This month's cover captures the flow of material from a protoplanetary disk to the surface of the star at its center. R. Mark Wilson and Heather M. Hill Webinar LIVE WEBINAR: Qubit control and measurement solutions to accelerate quantum computing applications Learn how to design and operate a qubit control setup working directly at microwave frequencies without IQ mixer calibration, using a simple Python interface to control the measurement instruments. Register now. FROM THE AUGUST MAGAZINE The structures of protoplanetary disks Astronomical observations of gas, dust, and rocky material in the disks from which planets emerge help refine theoretical ideas about how they form.
