July/August 2025 Read the Issue Dear Friend of Scientific American, Our expanded summer issue is here! For the cover feature, chief multimedia editor Jeffery DelViscio spent several weeks in the harsh icescape of Greenland, where he followed researchers drilling underneath a flowing ice tongue called the Northeast Greenland Ice Stream. If the ice sheet melts, much of the water will drain through this tongue into the ocean—an extremely worrying prospect.    The future of fashion is all about sustainability. Journalist Jessica Hullinger shows how organizations have launched creative initiatives to source fibers sustainably and to extend the lifetimes of purchased clothing. Plus, a color-coded consumer graphic can help you make better choices for your closet, and the Earth.    Also tucked in this issue, astronomer Yvette Cendes dives into a black hole mystery. Scientists wonder why these behemoths burp out some of their meals long after scarfing down star-filled snacks.    Children who show aggressive, callous and unemotional behaviors are at risk of developing psychopathy. Science writer Maia Szalavitz describes new treatments that can help these children grow into thriving adults.      Testosterone supplements are all the rage for men of a certain age. But do they live up to the hype? Science journalist Stephanie Pappas digs into the benefits and risks.   If you're interested in finding treasure this summer, you could get inspiration from metal detectorists who have brought the hobby to a professional level, particularly in Denmark. In this feature, meet some of these enthusiasts and see their sparkling discoveries.  To read the full issue and save 30%, consider a Digital subscription today!
