Valar Atomics Says It’s the First Nuclear Startup to Achieve Criticality
A Trump administration pilot program aims for three nuclear startups to reach a key milestone by July 4, 2026. Valar Atomics says it’s the first to do so—but it had some help.
Climate Change Made Hurricane Melissa 4 Times More Likely, Study Suggests
Unusually warm ocean temperatures fueled one of the worst hurricanes on record. New research finds climate change increased the storm’s likelihood.
In Orbit You Have to Slow Down to Speed Up
Driving a spacecraft around a planet isn’t anything like driving on a planet. A physicist explains orbital navigation.
How to Follow the Trajectory of Comet 3I/Atlas
The interstellar comet 3I/Atlas reached its closest point to the sun. Here's how to follow the rest of its journey away from our solar system.
Physicists Create a Thermometer for Measuring ‘Quantumness’
“Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it.
Hurricane Melissa Has Meteorologists Terrified
The storm, which is set to make landfall in Jamaica on Tuesday, has stunned meteorologists with its intensity and the speed at which it built.
No, ICE (Probably) Didn’t Buy Guided Missile Warheads
A federal contracting database lists an ICE payment for $61,218 with the payment code for “guided missile warheads and explosive components.” But it appears ICE simply entered the wrong code.
How Genes Have Harnessed Physics to Grow Living Things
The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development.
Teachers Get Death Threats After MAGA Claims Their Halloween Costumes Mocked Charlie Kirk
A Turning Point USA official inaccurately claimed a high school's math department wore Halloween costumes that mocked Charlie Kirk. Those teachers are now facing a flood of online attacks and death threats.

Nancy Mace Curses, Berates Confused Cops in Airport Meltdown: Police Report
At an airport in South Carolina on Thursday, US representative Nancy Mace called police officers “fucking incompetent” and berated them repeatedly, according to an incident report.
The ‘10 Martini’ Proof Connects Quantum Mechanics With Infinitely Intricate Mathematical Structures
The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number theory to explain quantum fractals.
