Forward this email  View in your browser THE WEEK IN PHYSICS: 24–28 MAY Advertisement Turbopumps for light gases New HiPace 350 and 450 turbopumps for 300 to 700 l/s applications provide high pumping speed for light gases. The integrated HiPace electronic drive unit provides a wide range of communication interfaces, without increasing the size. Remote and sensor functionalities enable pump data to be analyzed for optimum process monitoring during operation. HiPace turbopumps combines low weight and a small footprint, while a rugged bearing design ensures reliability with the pumps running maintenance-free for up to 5 years. Dune auroras shine light on atmospheric dynamics Their alternating pattern likely indicates a connection with waves in the upper mesosphere. Christine Middleton Commentary: The publication pandemic The open-access movement has spawned predatory journals that are proliferating, expanding, and damaging science. Paul Newton and Katepalli Sreenivasan Advertisement Innovate with NRO Research & Development Funding The National Reconnaissance Office Director's Innovation Initiative (DII) program funds cutting-edge, high-risk research to discover innovative concepts that transform overhead intelligence capabilities for future national intelligence needs. The program seeks the brightest minds and breakthrough technologies from industry, academia, national laboratories, and U.S. government agencies. FROM THE VAULT: December 2003 Stern and Gerlach: How a bad cigar helped reorient atomic physics The history of the Stern–Gerlach experiment reveals how persistence, accident, and luck can sometimes combine in just the right ways. Bretislav Friedrich and Dudley Herschbach Webinar Live webinar: Novel sources of tunable laser light Widely tunable continuous-wave optical parametric oscillators (CW OPOs) have matured into versatile laser light sources - how and why? We'll take a closer look at CW OPO design principles, critically examine performance highlights and limitations, and showcase some exciting real-world applications. Register now. Large systems can be controllably entangled and limitlessly measured A mechanical oscillator has quantum properties that can be directly observed. Rachel Berkowitz Companies and government agencies propose nuclear reactors for space The technologies could help the US Space Force monitor the region between Earth and the Moon. Sarah Scoles Webinar Live Webinar: Juno at Jupiter A NASA spacecraft in orbit about Jupiter is yielding new and surprising information about our solar system's dominant planet. We probe the deep interior with gravity and magnetic measurements and the atmosphere through microwaves, infrared and visible light images. We also explore Jupiter's aurora and polar magnetosphere and take astonishing pictures and will visit some Galilean moons. Register now. FROM THE MAY MAGAZINE One frog species finds a solution to the cocktail party problem A mechanism in the lungs of tree frogs helps filter incoming noise and other amphibian sounds from the calls of their own species.
