I have a new article just out, published as a Rapid Communication in Physical Review B. The work is a computational study co-authored with Duncan Mowbray and Mathias Ljungberg from San Sebastian, Spain, and Paola Ayala from Vienna. As described in the post about my recent review article, X-ray photoelectron spectroscopy is an extremely useful tool for studying… Continue reading Calculating the graphene C 1s core level binding energy — Mostly Physics

Ganymede Looks Glorious in New Images from NASA’s Juno Mission
The photos from a historic flyby of our solar system’s largest moon are starting to roll in. On Monday (June 7), NASA’s Juno probe zoomed within just 645 miles (1,038 kilometers) of Jupiter’s enormous satellite Ganymede, which is bigger than the planet Mercury. It was the closest any probe had come to Ganymede since May 2000, when NASA’s Galileo… Continue reading Ganymede Looks Glorious in New Images from NASA’s Juno Mission
Single Cells Evolve Large Multicellular Forms in Just Two Years
Imagine, then, that every time a new cluster forms, its experience recapitulates this process, with the same differences in the environments of the inner and outer cells driving the same divergent responses. You begin to see how the story of what was once a unicellular creature can be rewritten, its body a palimpsest of what… Continue reading Single Cells Evolve Large Multicellular Forms in Just Two Years
Why We Don’t Know the Animal Origins of the Coronavirus
Over the past century, many notable viruses have emerged from animals to cause widespread illness and death in people. The list includes the pathogens behind pandemic influenza, Ebola, Zika, West Nile fever, SARS and now COVID, brought on by the virus SARS-CoV-2. For all of these microbes, the animal species that served as the original source… Continue reading Why We Don’t Know the Animal Origins of the Coronavirus
We Are Beast Machines – Issue 107: The Edge
I have a childhood memory of looking in the bathroom mirror, and for the first time realizing that my experience at that precise moment—the experience of being me—would at some point come to an end, and that “I” would die. I must have been about 8 or 9 years old, and like all early memories… Continue reading We Are Beast Machines – Issue 107: The Edge
Neuroscience Weighs in on Physics’ Biggest Questions – Issue 107: The Edge
For an empirical science, physics can be remarkably dismissive of some of our most basic observations. We see objects existing in definite locations, but the wave nature of matter washes that away. We perceive time to flow, but how could it, really? We feel ourselves to be free agents, and that’s just quaint. Physicists like… Continue reading Neuroscience Weighs in on Physics’ Biggest Questions – Issue 107: The Edge
Saved from Shuckers, Oysters Fight Rising Seas
NEW YORK HARBOR—It’s an odd scene in New York Harbor. On the banks of tree-lined Governors Island, a small group has gathered to watch a tiny gray boat anchor itself in the water. Two figures lean over the side of the vessel, their red life vests standing out against the slate waves. Each clutches several… Continue reading Saved from Shuckers, Oysters Fight Rising Seas
The Spiritual Consciousness of Christof Koch – Issue 107: The Edge
Consciousness is a thriving industry. It’s not just the meditation retreats and ayahuasca shamans. Or the conferences with a heady mix of philosophers, quantum physicists, and Buddhist monks. Consciousness is a buzzing business in neuroscience labs and brain institutes. But it wasn’t always this way. Just a few decades ago, consciousness barely registered as a… Continue reading The Spiritual Consciousness of Christof Koch – Issue 107: The Edge
These Alternative Economies Are Inspirations for a Sustainable World
Scientific American June 2021 Making peace with the biosphere will require building communities and relationships that are focused on protecting life—human and nonhuman No one in her village faced food shortages during the lockdowns, nor did they suffer from COVID-19, Moligeri Chandramma assured me through an interpreter this past March. A farmer in the drylands… Continue reading These Alternative Economies Are Inspirations for a Sustainable World
Why People Feel Like Victims – Issue 99: Universality
In a polarized nation, victimhood is a badge of honor. It gives people strength. “The victim has become among the most important identity positions in American politics,” wrote Robert B. Horwitz, a communications professor at the University of California, San Diego. Horwitz published his study, “Politics as Victimhood, Victimhood as Politics,” in 2018.1 He focused… Continue reading Why People Feel Like Victims – Issue 99: Universality
