“with Brian Berzin — Co-Founder & CEO of Thea Energy.
What if we could build a fusion reactor that runs continuously—without the instability issues that have plagued the field for years?
Brian Berzin is the Co-Founder and CEO of Thea Energy (https://thea.energy/), a next-generation fusion company focused on advancing stellarator technology—one of the most promising but historically underexplored approaches to magnetic confinement fusion.
Brian brings a unique combination of deep technical and financial expertise, with a background spanning electrical engineering, venture capital, private equity, and investment banking.
Prior to founding Thea Energy, Brian served as Vice President of Strategy at General Fusion, where he helped shape commercialization strategy and led engagement with global capital markets during a pivotal period for privately funded fusion.
Heterogeneous catalysis—in which catalysts and reactants are of different phases, e.g., solid and gas—is important to many industrial processes and often involves solid metal as the catalyst. Ammonia synthesis, catalytic converters for automobile exhaust, methanol synthesis, carbon dioxide reduction, and hydrogen production are examples of such metal-catalyzed heterogeneous catalysis.
The electronic structure of metal surfaces governs the adsorption of reactants and intermediates, and thus the catalytic activity. For this reason, strain engineering —which tunes the electronic structure of a metal catalyst by stretching or compressing its crystal lattice—has emerged as an important strategy for enhancing catalytic performance. Unfortunately, scientists have not been able to quantify how metal strain influences adsorption energies and reaction barriers across different metal catalysts, thereby limiting the rational design of catalysts with desired properties.
To address this challenge, a research team from the Lanzhou Institute of Chemical Physics (LICP) of the Chinese Academy of Sciences has developed a method to predict how strain modifies adsorption energies and reaction barriers across diverse metal systems. The study is published in the journal Cell Reports Physical Science.
A pair of US researchers have developed a new model to tackle a deceptively simple problem: how a small block of ice melts while floating in calm water. Using an advanced experimental setup, Daisuke Noto and Hugo Ulloa at the University of Pennsylvania have captured the intricate dynamics that underlie this everyday process—work that could ultimately pave the way for more accurate predictions of melting sea ice. The study has been published in Science Advances.
If you place a block of ice in a glass of water, it will float at the surface and gradually melt. While this scenario seems simple at first glance, the dynamics involved are surprisingly complex: even if the surrounding water is completely still, the flow of heat from the warmer liquid into the colder ice generates motion that disrupts the system.
As the ice melts, it can begin drifting, spinning, or even flipping over. In turn, these motions alter the surrounding flow of water and heat, affecting the overall melting rate and making it remarkably difficult for physicists to predict how long the ice will last.
WASHINGTON — NASA modified operations of an astrophysics spacecraft in a decaying orbit to buy more time for a mission later this year that will attempt to raise its orbit.
Do you believe alien life could be completely unlike anything we’ve ever imagined? In this Science Documentary, we explore forms of life that may not need light, oxygen, or even a recognizable body—glowing through chemistry, drifting like gel in endless darkness, or existing as silent, stone-like structures. This Science Documentary follows the latest discoveries as telescopes probe distant worlds for signs of life. And closer to home, beneath thick ice, hidden oceans may already hold the first alien organisms humanity could reach.

An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive stars collapse into black holes—objects with gravity so strong that not even light can escape.
Some very massive stars, however, are expected to become so hot that they are blown apart in a pair-instability supernova—an explosion so intense that the star is completely disrupted, leaving behind no black hole.
First predicted in the 1960s, pair-instability supernovae are challenging to distinguish from more common stellar explosions that leave behind black holes.
A physics grad student waltzed away with the top prize in the 2026 Dance Your PhD contest.
Dance is the art of human movement. It combines motion and spin, energy and balance, synchronization and cadence. Many of these concepts are familiar to physicists—even those who might panic at the mere thought of being on a dance floor. Sofia Papa can give a lesson or two on the connections between physics and dance. A physics graduate student and professional dancer, Papa won the top prize this month in the annual Dance Your PhD contest, run by the journal Science. In the winning video, she and six other dancers mimic the internal workings of a piezoelectric, a type of material that turns atomic movement into electricity.
Papa has always loved dancing. “It was my first way to express myself,” she says. For several years now, she has complemented her physics education with dance training. While the dancing has served as a break from the rigors of studying, she has also used it as a way to work through difficult physical concepts. “I’ve always needed something creative to help understand complex ideas,” she says.
Deep beneath the Earth’s surface, a major physics experiment has reached a critical milestone, enabling detectors to operate at temperatures near absolute zero.
Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck Institute for Extraterrestrial Physics (MPE) has shown that moons around freefloating planets can keep their water oceans liquid for up to 4.3 billion years by virtue of dense hydrogen atmospheres and tidal heating—that is to say, for almost as long as Earth has existed and sufficient time for complex life to develop.
Planetary systems often form under unstable conditions. If young planets come too close, they can fling each other out of their orbits. This creates free-floating planets (FFPs) that wander through the galaxy without a parent star. An earlier study by LMU physicist Dr. Giulia Roccetti had shown that gas giants ejected in this way do not necessarily lose all of their moons in the process. The new study is published in the Monthly Notices of the Royal Astronomical Society.
Tidal heating keeps oceans liquid The ejection does, however, alter the orbits of the moons. They become highly elliptical, such that their distance from the planet constantly changes. The resulting tidal forces rhythmically deform the lunar body, compress its interior, and generate heat through friction. This tidal heating can be sufficient to maintain oceans of liquid water on the surface—even without the energy of a star, and in the cold of interstellar space.
