The Usefulness of a Memory Guides Where the Brain Saves It
New research finds that the memories useful for future generalizations are held in the brain separately from those recording unusual events.
New Codes Could Make Quantum Computing 10 Times More Efficient
Quantum computing is still really, really hard. But the rise of a powerful class of error-correcting codes suggests that the task might be slightly more feasible than many feared.
Quaking Giants Might Solve the Mysteries of Stellar Magnetism
In their jiggles and shakes, red giant stars encode a record of the magnetic fields near their cores.
Math Proof Draws New Boundaries Around Black Hole Formation
For a half century, mathematicians have tried to define the exact circumstances under which a black hole is destined to exist. A new proof shows how a cube can help answer the question.
Risky Giant Steps Can Solve Optimization Problems Faster
New results break with decades of conventional wisdom for the gradient descent algorithm.
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.
Ninth Dedekind Number Found by Two Independent Groups
The numbers count a variety of seemingly unrelated mathematical structures.
