My routine morning jog at sunrise was slightly delayed today by an early television interview on the CBC News Network in Canada. Natalie Kalata asked me for the significance of the sample return from the asteroid Bennu today and I replied: “It feels like touching a piece of sky.” When…

There are many popularizers of science, including journalists, bloggers and those who call themselves “astrophysicists” without writing a single scientific paper for decades. But there are only a few practicing scientists who engage the public in their ongoing research. Just as sport commentators suggest to soccer players how to pass…

My Harvard colleague and 2007 Nobel laureate in Economics, Eric Maskin, invited me last night to dinner in the company of the 2017 Nobel Laureate in molecular biology, Michael Rosbash. As soon as the three of us sat down, Michael said: “The discovery of recombinant DNA changes everything in my…

The absolute silence dominated my routine jog this morning along an empty path, with the rising sun as my only companion. I was struck by how lonely we can be in the company of physical objects, even as magnificent as this giant fusion reactor situated 8.33 light-minutes away. This sense…

Over the past week, I received hundreds of emails inspired by the new findings from the expedition to the Pacific Ocean, as summarized in a new scientific paper, accessible here. Below is a representative sample of these letters to illustrate that innovation in scientific research is worthwhile well beyond the…

Now that we measured the composition of the first recognized interstellar meteor, IM1, can we recreate its material making in the laboratory? The stress tolerated by IM1 before it disintegrated implies that it was tougher than iron meteorites in the solar system. This raises important questions: what was IM1’s melting…
