Experiment resolves long-standing iron-spectrum discrepancy Forward this email  View in your browser THE WEEK IN PHYSICS: 30 JANUARY–3 FEBRUARY Advertisement It's Always Safer to have Backup Get the added safety of a backup system when handling hazardous and/or expensive gases and vapors. KNF LeakTight pumps offer ultra-low leak rates of <6×10-6 mbar L/sec and a safety back-up diaphragm, plus safeguards against intrusion contamination. Flow rates from 15 – 290 L/min. Options include explosion-proof motors and material choices. Learn more. Ionocaloric refrigeration makes its debut Adding salt to a material lowers its melting point and removes heat. New research makes that process reversible and produces an efficient cycle under an applied voltage. R. Mark Wilson Experiment resolves long-standing iron-spectrum discrepancy New measurements of two emission lines that are widely studied by x-ray astronomers finally match theoretical predictions, just in time for the launch of a new telescope. Daniel Garisto Live webinar Actions to Advance Equity, Diversity, and Inclusion in Physics Across science, many groups of people continue to be underrepresented, and representation gaps appear set to persist for a long time. For example, it is projected to take 258 years to reach gender parity in physics. What factors lead to disparities in representation? What are the challenges faced by equity-deserving groups? Why should we be motivated to effect change? What can we do? Register Now. FROM THE VAULT: September 2014 What we know and don't know about tornado formation Forecasters would love to predict violent weather with more accuracy and longer lead times. Researchers are helping them by unraveling the science behind the complex sequence of events that lead to tornadoes. Paul Markowski and Yvette Richardson Did polluted skies influence Impressionist art? Over the 19th century, the color contrast of some painters' works dropped as industrial emissions rose. Heather M. Hill Behind the Cover: February 2023 Clogging can take place whenever a suspension of discrete objects flows through a confined space. R.
