Insects inspire ink for 4D printing Objects made through additive manufacturing can display iridescent colors that change in response to humidity. Christine Middleton Tonga eruption whipped up the atmosphere The volcano triggered waves with unprecedented speed and longevity that reached as high as the ionosphere. Andrew Grant FROM THE VAULT: August 1975 Magnetic fields of the human body Developments in ways to measure the extremely weak magnetic fields emanating from organs such as the heart, brain and lungs are leading to important new methods for diagnosing abnormal conditions. David Cohen Webinar Live webinar: Cryogenic Raman imaging and spectroscopy This presentation will describe cryogenic Raman imaging before providing application examples that demonstrate its ability to take molecular characterization right to the edge of absolute zero, with full polarization control and in high magnetic fields. Register now. Topological insulator without the insulating states A fractal structure can support topologically protected transport along its many edges. Heather M. Hill You might have missed Commentary: How to determine the right conditions for alien life To develop best practices for evaluating the habitability of extraterrestrial environments, astrobiologists should learn from the work of ecologists studying life on Earth. Abel MÉndez Webinar Live Webinar: Simulating Metamaterials with COMSOL Multiphysics® Metamaterials and metasurfaces have received an increasing amount of interest in academia and industry over the past twenty years. This is because specifically designed metamaterials can control electromagnetic waves in previously unprecedented ways. This degree of electromagnetic control goes beyond what is possible when using conventional materials. In this webinar we will cover the basics of metamaterials and metasurfaces and demonstrate how their behavior can be simulated using COMSOL Multiphysics®. Register now. FROM THE JULY MAGAZINE Building a ship in a bottle for neutrino science In a former gold mine in South Dakota, an international particle-physics experiment will delve into the unexplained matter–antimatter imbalance that gave rise to the universe.
