Genes Have Harnessed Physics to Help 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.
Loops of DNA Equipped Ancient Life To Become Complex
New work shows that physical folding of the genome to control genes located far away may have been an early evolutionary development.
Origami Patterns Solve a Major Physics Riddle
The amplituhedron, a shape at the heart of particle physics, appears to be deeply connected to the mathematics of paper folding.
How One AI Model Creates a Physical Intuition of Its Environment
The V-JEPA system uses ordinary videos to understand the physics of the real world.
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.
New Math Revives Geometry’s Oldest Problems
Using a relatively young theory, a team of mathematicians has started to answer questions whose roots lie at the very beginning of mathematics.
To Understand AI, Watch How It Evolves
Naomi Saphra thinks that most research into language models focuses too much on the finished product. She’s mining the history of their training for insights into why these systems work the way they do.
A Simple Way To Measure Knots Has Come Unraveled
Two mathematicians have proved that a straightforward question — how hard is it to untie a knot? — has a complicated answer.

The Quantum Mechanics of Greenhouse Gases
Earth’s radiation can send some molecules spinning or vibrating, which is what makes them greenhouse gases. This infographic explains how relatively few heat-trapping molecules can have a planetary effect.
