In Fake Universes, Evidence for String Theory

If string theorists can show that their framework is the only consistent theory of quantum gravity, does that make it true even without tangible evidence?


Game Theory Calls Cooperation Into Question

A new solution to the prisoner’s dilemma, a classic game theory scenario, has created new puzzles in evolutionary biology.


Breakthrough DNA Editor Born of Bacteria

Interest in a powerful DNA editing tool called CRISPR has revealed that bacteria are far more sophisticated than anyone imagined.


Joint Dust Analysis Deflates Big Bang Signal

No definitive evidence for cosmic inflation is found, but support remains strong for the theory even as critics highlight its shortcomings as an explanation for how and why the universe began.


Networks Reveal the Connections of Disease

Disease is the result of failure somewhere along the line in a complex dance of biological components. Now statistical physicists are using enormous databases of medical records to study connections between illnesses.


Quantum Computing Without Qubits

A quantum computing pioneer explains why the near future of quantum computation may lie in simulators, not general-purpose quantum machines.


A Proof That Some Spaces Can’t Be Cut

Mathematicians have solved the century-old triangulation conjecture, a major problem in topology that asks whether all spaces can be subdivided into smaller units.


Scientists Conjure Curves From Flatness

Researchers have found a set of rules for imbuing flat surfaces with curvature, enabling them to form a virtually unlimited range of three-dimensional structures.
