New Issue: May 2026 Read the Issue Dear Friend of Scientific American, If watching the Artemis II mission has you daydreaming about visiting space, I have good news: Orbital tourism is getting closer to reality. You can find out how in the new issue of Scientific American, which includes a special look at the science of luxury, from the long road to space hotels to the cutting‑edge chemistry behind high‑end fragrances.    Our cover story explains how here on Earth, medical researchers are tackling their own moonshot: A quarter of the people admitted to hospitals for heart attacks and strokes don’t exhibit expected risk factors, and cardiologists don’t know why. But new research points to a hidden culprit for heart disease and could lead to innovative treatments.     You’ll also learn why birds—and only birds—survived the asteroid impact that wiped out every other dinosaur in the end-Cretaceous mass extinction. You’ll join the biologists who are racing to understand the mysterious collapse of America’s freshwater mussels. And you’ll visit the high-tech labs where researchers are investigating materials with strange magnetic properties that could change physics and upend computing.     Science starts in unexpected places. I hope this issue takes you somewhere new.   You can enjoy the full issue with up to 47% off a subscription, an exclusive offer just for you. ​ Chase wonder, catch truth, David M. Ewalt Editor in Chief
