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.
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.
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.
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.
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.
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.
An Invasive Disease-Carrying Mosquito Has Spread to the Rocky Mountains
The Aedes aegypti mosquito that can carry dengue, yellow fever, and Zika was thought to be too reliant on a hot and wet climate to survive in the Mountain West. But now, a population is thriving in Western Colorado.
Unpicking How to Measure the Complexity of Knots
Two mathematicians have proved that a straightforward question—how hard is it to untie a knot?—has a complicated answer.
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.
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.
Can a Hydroelectric Dam Really Make the Days Longer?
By shifting water to a higher elevation, the giant Three Gorges Dam caused the Earth to spin more slowly.
How Do Metal Detectors Work?
What sneaky invisible forces enable these instruments to locate buried treasure?
