Theory and experiment disagree on alpha particles Electron-scattering experiments on excited helium nuclei open questions about the accuracy and sensitivity of state-of-the-art nuclear models. Heather M. Hill New project aims to shrink the x-ray free-electron laser Led by Arizona State University, the NSF-funded initiative is expected to increase researchers' access to the XFEL's unique capabilities. David Kramer Live webinar Live webinar—Quantum Measurement and Why It's a Problem Quantum mechanics has been our most successful fundamental theory of nature since the 1920s, but we still don't fully understand what the theory actually says. Sean Carroll will discuss what the problem is, why it is important, and how a better understanding could help us with other pressing problems in physics. Register Now. FROM THE VAULT: March 2019 Venus is not Earth's closest neighbor Calculations and simulations confirm that on average, Mercury is the nearest planet to Earth—and to every other planet in the solar system.

Birefringent nanospheres help give a shrimp its bright white stripe Researchers use cryo-scanning electron microscopy to peer beneath the shrimp's transparent cuticle to study pigment cells. Jennifer Sieben JWST images the disk around a young star Containing dust and debris akin to an asteroid belt, the disk of Fomalhaut is evidence of a complex and active planetary system. R. Mark Wilson Live webinar Live webinar—Quantum Materials: From Characterization to Resonator Measurements Understanding and addressing materials losses is key to implementing the next generation of quantum technology. In this webinar, you will learn how low-noise measurements with lock-in amplifiers can help you optimize your materials. Register Now. FROM THE MAY MAGAZINE The cloud dynamics of convective storm systems Through a combination of idealized simulations and real-world data, researchers are uncovering how internal feedbacks and large-scale motions influence cloud dynamics.
