Technologies That Shape the World: 2018 Edition
“The advocate of industry and enterprise, and journal of mechanical and other improvements”: that mission visually underscored the logo of our very first issue, dated Thursday, August 28, 1845. In the latest installment of Scientific American's delivery on that promise, we bring you this month's cover story, “Top 10 Emerging Technologies of 2018,” a collaboration between Scientific American and… → Read More
Precision Medicine's Promise and Progress
As gene-based therapies move from lab to clinic, how can business and government bridge the gap between availability and access? → Read More
Science at Davos: Nanomachines, the Microbiome and Funding Frontier Research
Having kicked off the week at the 48th annual World Economic Forum meeting at Davos by moderating a panel conversation around the challenges and opportunities for the “Global Science Outlook” in the coming year, I spent today in a series of fascinating discussions that highlighted the power of science to help in advancing discovery and addressing humanity’s grand challenges. A couple of them… → Read More
How Did Life Begin on Earth?
There was light. But then what happened? How did life arise on the third rocky planet orbiting the unremarkable star at the center of our solar system? Humans have been wondering about the answer to that question probably almost as long as we've been able to wonder. In recent decades scientists have made some gains in understanding the conceivable mechanisms, gradually settling on a possible… → Read More

To Boldly Go to the Nearest Star and the Distant Past
Before kindergarten, I was already dreaming about the wonders of interstellar space travel. I saw the Apollo astronauts walk on the moon and enjoyed the weekly exploits of the crew of the Enterprise on the original Star Trek TV episodes. It seemed we'd soon be leaping into that “final frontier.” But the adult me now knows a lot more about how hard it is to explore the cold vastness of space—even… → Read More
After the U.S. Election, What's Next for Science?
Wednesday, November 9, dawned gray and raw in Berlin. I was there to moderate a couple of panels at an annual meeting called Falling Walls. The name and timing celebrate the anniversary of the Berlin Wall's fall, as well as the free exchange of ideas if only we can knock down barriers. I looked forward to a series of inspiring talks about how science, which I have often called the “engine of… → Read More
Ideas to Change the World: From Emerging Technologies to Family-Friendly Policies
It's no secret we at Scientific American are fans of the kinds of bold ideas that can help take humanity to a better future. Recently technology, especially digital, seems to be advancing more swiftly than ever. Noting the trend, even the policy leaders at the World Economic Forum's Davos meeting this year focused on the theme of the “Fourth Industrial Revolution.” Of course, a bane of any given… → Read More
Theory and Truth: Quantum Gravity versus 5 Unassailable Scientific Facts
In 1935 Albert Einstein and his collaborators wrote two papers about what seemed to be vastly different things. One, which he famously later described uncomfortably as “spooky action at a distance,” is quantum entanglement: a surprising connection between objects, such as atoms or subatomic particles, which may be quite far apart. The other is wormholes, shortcuts between distant regions of… → Read More
New Views: See-Through Brains, the World's Science, Enceladus's Oceans
We often casually say that we are “hardwired” to feel certain ways or to have specific responses to events. But what do we really know about that neural wiring? How does it wend through the gelatinlike brain that contains all our hopes and dreams, all that makes us who we are? First of all, the telecom analogy isn't that far off. Our nervous system uses the fibers known as axons to ferry… → Read More
