Dark Matter Gets a Reprieve in New Analysis
A strange glow coming from the Milky Way’s center was thought to be due to ordinary pulsars. But a new look at a years-old study shows that dark matter might still be responsible.
Scientists Discover Nearly 200,000 Kinds of Ocean Viruses
New work raises the estimated diversity of viruses in the seas more than twelvefold and lays the groundwork for a better understanding of their impact on global nutrient cycles.
A New Approach to Multiplication Opens the Door to Better Quantum Computers
Quantum computers can’t selectively forget information. A new algorithm for multiplication shows a way around that problem.
Viruses Have a Secret, Altruistic Social Life
Researchers are beginning to understand the ways in which viruses strategically manipulate and cooperate with one another.
In Quantum Games, There’s No Way to Play the Odds
These games combine quantum entanglement, infinity and impossible-to-calculate winning probabilities. But if researchers can crack them, they’ll reveal deep mathematical secrets.
Goals and Rewards Redraw the Brain’s Map of the World
Two new studies show that the brain’s navigation system changes how it represents physical space to reflect personal experience.
Sum-of-Three-Cubes Problem Solved for ‘Stubborn’ Number 33
A number theorist with programming prowess has found a solution to 33 = x³ + y³ + z³, a much-studied equation that went unsolved for 64 years.
Galaxy Simulations Offer a New Solution to the Fermi Paradox
Astronomers claim in a new paper that star motions should make it easy for civilizations to spread across the galaxy, but still we might find ourselves alone.
The Physics Still Hiding in the Higgs Boson
No new particles have been found at the Large Hadron Collider since the Higgs boson in 2012, but physicists say there’s much we can still learn from the Higgs itself.
