Jamming links granulation and flow A unified model that describes how powders behave when they get wet could inform industrial processing of such disparate products as gunpowder and chocolate. Christine Middleton Microcombs enhance silicon photonic chips Once integrated, cost-efficient microcombs can be customized for applications ranging from data communication to optical neural networks. Gizem Doğan Webinar Live Webinar: Quantum Steampunk: The Physics of Yesterday's Tomorrow Steampunk—a science-fiction genre that juxtaposes 19th-century settings with futuristic technologies—is coming to life. Cutting-edge quantum information science is revitalizing the Victorian science of energy in the growing field of quantum thermodynamics. Register now. FROM THE VAULT: December 1950 Physics in the watch industry Examining the physical problems besetting watchmakers in their effort to mass produce ever smaller and more accurate time pieces. J. A. Van Horn Advertisement Enter the Anthropocene: Climate Science in the Early 20th Century In the second episode of a 12-week podcast on untold physics history, we discuss the efforts of three scientists—Svante Arrhenius, Guy Callendar, and Charles David Keeling—to figure out exactly what all those fossil fuel emissions might be doing to the atmosphere and the global temperature. Surprisingly, Arrhenius didn't necessarily think that global warming would be such a bad thing? Listen now. In last-minute shuffle, Switzerland hosts virtual International Physics Olympiad The annual competition for high school students went on, but not in Belarus as originally planned. Gizem Doğan CHIPS and Science Act heads to Biden's desk The historic legislation provides more than $50 billion to the semiconductor sector and lays out ambitious expansion plans for some federal science agencies. Mitch Ambrose and William Thomas Webinar Live Webinar: Cryogenic Electron Microscopy and Tomography Cryogenic electron microscopy and tomography have emerged rapidly in the last few years. Researchers are resolving structural features of protein machines, RNAs, and viruses that can be analyzed in terms of functions and dynamics. Tomography is also revealing subnanometer-resolution structures of macromolecules undergoing different biological processes in situ. Register now. FROM THE AUGUST MAGAZINE Einstein would be doubly amazed Quantum-correlated light embodies all the weirdness of quantum physics. Now it is being used to aid in the observation of another exotic phenomenon: gravitational waves.
