The week in physics: Oceans from asteroids; Keeping time in space; Additive printing with a twist

Could asteroids have supplied enough water to fill Earth's oceans? Forward this email  View in your browser THE WEEK IN PHYSICS: 12–16 JULY Could asteroids have supplied enough water to fill Earth's oceans? A new numerical study suggests that the answer depends upon how much water is in Earth's mantle. Charles Day Viscoelastic fluids with no strings attached Dispensing a fluid is quick and clean when the nozzle is rotated. Heather M. Hill Webinar LIVE WEBINAR: Quantum Orchestration for Quantum Error Correction Quantum error correction is an essential aspect of superconducting quantum computing, but it faces various control challenges. We will discuss concatenated cat codes and demonstrate how the Quantum Orchestration Platform allows users to overcome these challenges and optimize performance. Register now. FROM THE VAULT: November 1999 Television goes digital The new technology is bringing images of unprecedented clarity into our homes by exploiting the existing bandwidth and pushing signal‐to‐noise ratios almost to their theoretical limits. Louis A. Bloomfield Webinar LIVE WEBINAR: Juggling Dynamics Dynamical prediction and muscle memory allow jugglers to easily control seemingly impossible patterns of motion. This webinar features juggling demonstrations and interactive components in an introduction to the mathematics and physics of juggling from the perspective of stability analysis. Register now. Behind the Cover: July 2021 Hyperaccumulator plants extract metals from soils and incorporate them into their biomass. Our cover shows the chemical elements in live seedlings of one such plant.
