Galactic archaeologists trace the evolution of the Milky Way Forward this email  View in your browser THE WEEK IN PHYSICS: 7–11 NOVEMBER Galactic archaeologists trace the evolution of the Milky Way Improved methods of estimating the ages of stars, combined with new precision position and velocity data, are yielding insights into the major events that shaped our galaxy billions of years ago. Rachel Brazil Martian concrete could be tough stuff Construction materials on the red planet would inevitably differ from their counterparts on Earth. But researchers are starting to get an idea of their potential mechanical properties. Johanna L. Miller Webinar Live Webinar: Innovative Femtosecond Lasers for Multiphoton Applications With advances in ultrashort pulses in the sub 50 fs regime, fiber-based femtosecond lasers have become a cost-efficient laser source for multiphoton applications. In this webinar we introduce femtosecond fiber laser technology and explore different applications in biomedical imaging, polymerization as well as in-line quality screening via terahertz spectroscopy.

But because the top quark is so massive, it eluded experimental detection for nearly two decades. Dmitri Denisov and Costas Vellidis Advertisement Call for Submissions: NASA StarShade Undergraduate Challenge NASA's Hybrid Observatory for Earth-like Exoplanets team is seeking undergraduate students to design and construct an orbiting starshade that could help examine extreme exoplanets from an Earth-stationed observatory. Students are encouraged to form teams from their local departments or universities. The deadline for phase 1 submissions is 12/15. Learn more. Keeping time with highly charged ions A new optical clock is less sensitive to outside influences and more sensitive to the ions' nuclear structure. Heather M. Hill Gravitational lens brings an ancient supernova into view Analysis of the 11.5-billion-year-old explosion, revealed in archival Hubble telescope data, helps constrain the populations of massive stars in the early universe. Andrew Grant Webinar Hands-On Superconducting Qubit Characterization Webinar This webinar will introduce essential methods used in superconducting qubit characterization, including qubit spectroscopy, single-shot readout, and Rabi oscillation measurements. Through tutorials and demonstrations, we will lead you from theory to practical, experimental measurements that are carried out on real qubits in a dilution refrigerator. Register now. FROM THE NOVEMBER MAGAZINE Time-reversed laser absorbs nearly all light A simple design overcomes a substantial limitation on potential applications for coherent perfect absorbers. Heather M.
