Powerful ‘Machine Scientists’ Distill the Laws of Physics From Raw Data
Researchers say we’re on the cusp of “GoPro physics,” where a camera can point at an event and an algorithm can identify the underlying physics equation.
Why ‘De-Extinction’ Is Impossible (But Could Work Anyway)
Several projects are aiming to bring back mammoths and other species that have vanished from the planet. Whether that’s technically possible is beside the point.
In Test Tubes, RNA Molecules Evolve Into a Tiny Ecosystem
When researchers gave a genetic molecule the ability to replicate, it evolved over time into a complex network of “hosts” and “parasites” that both competed and cooperated to survive.
Where Do Space, Time and Gravity Come From?
Einstein’s description of curved space-time doesn’t easily mesh with a universe made up of quantum wavefunctions. Theoretical physicist Sean Carroll discusses the quest for quantum gravity with host Steven Strogatz.
Think of a Number. How Do Math Magicians Know What It Is?
Mathematical magic can seem like mind reading. Your job is to reveal the secret behind these four tricks.
Physicists Pin Down How Quantum Uncertainty Sharpens Measurements
Throwing out data seems to make measurements of distances and angles more precise. The reason why has been traced to Heisenberg’s uncertainty principle.
Mathematicians Coax Fluid Equations Into Nonphysical Solutions
The famed Navier-Stokes equations can lead to cases where more than one result is possible, but only in an extremely narrow set of situations.
Secrets of the Moon’s Permanent Shadows Are Coming to Light
Robots are about to venture into the sunless depths of lunar craters to investigate ancient water ice trapped there, while remote studies find hints about how water arrives on rocky worlds.
What Happens When We Give Animals Our Diseases?
While it’s understandable to focus on the diseases affecting humans, it’s important to study how our illnesses may affect animals.
