Forward this email  View in your browser THE WEEK IN PHYSICS: 13–17 JUNE Magnetic field induces spatially varying superconductivity Strontium ruthenate may exhibit an exotic superconducting state composed of electron pairs with nonzero momentum. Heather M. Hill Permafrost is an undefined variable in the climate equation Russia is home to the bulk of the Arctic's permafrost. The country's invasion of Ukraine jeopardizes a new initiative to pin down how thawing will impact climate change. David Kramer Advertisement Silicon Carbide --- Top Choice for High Temperature Wear Several grades of this material optimize wear performance for bearings and other parts requiring extreme precision in high acceleration or aerospace applications. Insaco specializes in precision machining SiC where thermal conductivity or strength at high temperatures and low density are key. Learn more. FROM THE VAULT: February 1976 Scientists with a secret While the Nazi war machine was gearing up, a few physicists realized that a fission chain reaction was feasible—would they be able to get all groups to agree to hold back publication? Spencer R. Weart Webinar Live Webinar: Designing Biomimetic Colloidal Assembly of Active Materials How does nature build materials that make cells move, divide, and multiply? Pushing everything away from equilibrium by consumption of fuels might be the answer! During this webinar, we will show how to take these fuel-dependent processes and translate them to synthetic colloidal systems in a quest for new dynamic materials. Register now. Commentary: How to determine the right conditions for alien life To develop best practices for evaluating the habitability of extraterrestrial environments, astrobiologists should learn from the work of ecologists studying life on Earth. Abel Méndez A triatomic molecule is laser cooled and trapped With the advance from two atoms to three—and even more—the molecules amenable to ultracold techniques may start to resemble ones most chemists recognize. Johanna L. Miller Webinar Live webinar: Cryogenic Raman imaging and spectroscopy This presentation will describe cryogenic Raman imaging before providing application examples that demonstrate its ability to take molecular characterization right to the edge of absolute zero, with full polarization control and in high magnetic fields. Register now. FROM THE JUNE MAGAZINE Photonic waveguides shed their cladding The slimmed-down conduits avoid cross talk between adjacent channels by using materials that support different wave modes.
