When Popular Science

Every year since 1988, Popular Science has highlighted the innovations that make living on Earth even a tiny bit better. And this year—our 35th—has been remarkable, thanks to the successful deployment of the JWST, which earned our highest honor as the Innovation of the Year. But it’s just one item out of the 100 stellar technological accomplishments our editors have selected to recognize. The list below represents months of research, testing, discussion, and debate. It celebrates exciting inventions that are improving our lives in ways both big and small. These technologies and discoveries are teaching us about the nature of the universe and treating diseases, but they’re also giving us better ways of entertaining and expressing ourselves. With 10 categories spanning from aerospace to sports and outdoors, the list is a doozy. We’ve got Naval fighter jets on the big screen and TikTok filters on your phone. There’s gear to help you explore the great outdoors, and devices to help you improve your health and home. We’ve got gadgets galore, a very long suspension bridge, and an EV with a range of 747 miles. So buckle up, and explore the winners below. When we wrapped last year’s Best of What’s New awards, the staff wasn’t certain about what lay ahead. COVID-19 vaccines on their way into the public’s arms sparked hope, but signs of a looming supply-chain pinch left us wondering about the potential of the year in innovation to come. So, as we gathered to debate the winners, we were to be, well, underwhelmed. But what we found instead inspired quite the opposite reaction: Faced with the challenges of limited resources, a chip shortage, and an ongoing pandemic, engineers, developers, and scientists did a lot with what they had. Across all our 10 categories, gains in efficiency showcased our collective drive to optimize our world. A new hair-washing system creates a luxurious lather with less water, a spin on steelmaking spits out a mere fraction of the carbon, a clever AI plans airline routes for maximum efficiency, and a simple riff on a remote control zaps the need for disposable batteries. And, all the while, our push against the pandemic netted gains in prevention, testing, and treatment that will form the backbone of our resistance to the disease for years to come. To earn a spot among the 100 technologies on this list—a roundup we’ve argued over annually since 1988—every winner convinced us of its role on our shared path to a healthier, safer, smarter, and happier tomorrow. Across all our 10 categories, gains in efficiency showcased our collective drive to optimize our world.
