The week in physics: Hydrogen production; Insight on Mars's core

Solar-powered hydrogen production scales beyond the lab. Forward this email View in your browser THE WEEK IN PHYSICS: 24–28 APRIL Advertisement Faster Laser Communication with Steering Mirrors Responding to the higher data transmission rates demand, communication via laser beams, terrestrial, ground-to-satellite, and satellite-to-satellite is opening up new possibilities. Different technologies are available to provide the speed and precision needed to keep laser beams stabilized and pointed in the right direction, making sure they reach their targets exactly, over thousands of miles. See our solution. Solar-powered hydrogen production scales beyond the lab Researchers navigated the gulf between lab demonstrations and commercial-scale feasibility by solving a series of engineering-design challenges. Alex Lopatka Data from NASA's InSight sharpen our look at Mars's core The lander's seismometer resolved the seismic signals of a meteorite impact and a marsquake—both having originated from the planet's far side. R. Mark Wilson Live webinar Live webinar: The Physics of Active Matter Birds flock. Bees swarm. Fish school. These remarkable examples of natural collective behavior inspired researchers to study active matter—matter made not of atoms and molecules but of entities that consume energy to generate their own motion and forces. This unusual class of nonequilibrium systems can exhibit remarkable self-organization. Register Now.

Alex Lopatka You might have missed The drought of experimental neutrons in the US nears its end The NIST research reactor will resume operations this spring before shutting down again in about a year for upgrades. 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.
