JWST Spots Giant Black Holes All Over the Early Universe
Giant black holes were supposed to be bit players in the early cosmic story. But recent James Webb Space Telescope observations are finding an unexpected abundance of the beasts.
Risky Giant Steps Can Solve Optimization Problems Faster
New results break with decades of conventional wisdom for the gradient descent algorithm.
Two Students Unravel a Widely Believed Math Conjecture
Mathematicians thought they were on the cusp of proving a conjecture about the ancient structures known as Apollonian circles. But a summer project would lead to its downfall.
Even Synthetic Life Forms With a Tiny Genome Can Evolve
By watching “minimal” cells regain the fitness they lost, researchers are testing whether a genome can be too simple to evolve.
Exoplanets Could Help Us Learn How Planets Make Magnetism
New observations of a faraway rocky world that might have its own magnetic field could help astronomers understand the seemingly haphazard magnetic fields swaddling our solar system’s planets.
Selfish, Virus-Like DNA Can Carry Genes Between Species
Genetic elements called Mavericks that have some viral features could be responsible for the large-scale smuggling of DNA between species.
New Calculations Show How to Escape Hawking’s Black Hole Paradox
Inside of a black hole, the two theoretical pillars of 20th-century physics appear to clash. Now a group of young physicists think they have resolved the conflict by appealing to the central pillar of the new century — the physics of quantum information.
Ninth Dedekind Number Found by Two Independent Groups
The numbers count a variety of seemingly unrelated mathematical structures.
How Genetic Surprises Complicate the Old Doctrine of DNA
For over a century, biologists have had to contend with a complicated picture of genetics, which they’ve only recently begun to understand.
