a, We levitate a 500-μm silica sphere in an acoustic trap above a silica target plate. b, Charge is measured by applying a frequency-swept electric field, E(t), and extracting the

The new MultiQ-IT prototype can cool, trap, filter, and redirect over a billion ionssimultaneously, dramatically improving dynamic range and signal-to-noise. Credit Lori Chertoff/The Rockefeller University Editor’s note: with recent speculation

Eimission spectra of 3I/ATLAS taken with BFOSC and YFOSC. For clarity, the full spectral range is divided into three panels with different vertical offsets to emphasize specific features. The left

With the Munsell Soil Colour Chart the cores are described visually in colour and structure as acurately as possible. Photo: Diekamp@ECORD_IODP3_NSF Credit Diekamp@ECORD_IODP3_NSF The goal of this expedition went far

Collisions between leftover planetesimals drives the redistribution of mass between bodies of different sizes, generating a so-called collisional size-frequency distribution (SFD) dominated, in number, by the smallest bodies. The Earth
