Dear Reader,
Astronomers know surprisingly little about the structure of the Milky Way galaxy, but recently they produced the best map yet of our cosmic home. Today's lead story, featured on the cover of our April issue, explains what we're learning from this new view. Next up, some scientists say repopulating the Arctic with large herds of animals—the type that roamed the region thousands of years ago—could prevent permafrost from thawing out, even as temperatures rise. And lastly, a new technique can send ultrasonic waves through solid objects. This could enable hackers to avoid obstacles and perform more invasive tasks like stealing text messages and making calls from a stranger's phone. As a reminder, we are providing free access to all of our COVID-19 coverage as we continue to follow the pandemic. |
