Is Particle Physics Dead, Dying, or Just Hard?
Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.
Using AI, Mathematicians Find Hidden Glitches in Fluid Equations
A $1 million prize awaits anyone who can show where the math of fluid flow breaks down. With specially trained AI systems, researchers have found a slew of new candidates in simpler versions of the problem.
Distinct AI Models Seem To Converge On How They Encode Reality
Is the inside of a vision model at all like a language model? Researchers argue that as the models grow more powerful, they may be converging toward a singular “Platonic” way to represent the world.
How Dad’s Fitness May Be Packaged and Passed Down in Sperm RNA
Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has become impossible to ignore.
Cryptographers Show That AI Protections Will Always Have Holes
Large language models such as ChatGPT come with filters to keep certain info from getting out. A new mathematical argument shows that systems like this can never be completely safe.
Mixing Is the Heartbeat of Deep Lakes. At Crater Lake, It’s Slowing Down.
The physics of mixing water layers — an interplay of wind, climate and more — makes lakes work. When it stops, impacts can ripple across an ecosystem.
First Shape Found That Can’t Pass Through Itself
After more than three centuries, a geometry problem that originated with a royal bet has been solved.
The Game Theory of How Algorithms Can Drive Up Prices
Recent findings reveal that even simple pricing algorithms can make things more expensive.
How the Brain Moves From Waking Life to Sleep (and Back Again)
Neuroscientists probing the boundary between sleep and awareness are finding many types of liminal states, which help explain the sleep disorders that can result when sleep transitions go wrong.
