Famous Fluid Equations Are Incomplete
A 115-year effort to bridge the particle and fluid descriptions of nature has led mathematicians to an unexpected answer.
New Letters Added to the Genetic Alphabet
Scientists hope that new genetic letters, created in the lab, will endow DNA with new powers.
Decoding the Remarkable Algorithms of Ants
The biologist Deborah Gordon has uncovered how ant colonies search efficiently without central organization, an insight that might improve computer networks.
The Fuzzball Fix for a Black Hole Paradox
By replacing black holes with fuzzballs — dense, star-like objects from string theory — researchers think they can avoid some knotty paradoxes at the edge of physics.
Biologists Invoke the Past in Modern Bacteria
By swapping ancient genes into modern E. coli, scientists hope to tease out the rules of evolution.
A Design Dilemma Solved, Minus Designs
A 150-year-old conundrum about how to group people has been solved, but many puzzles remain.
A Private View of Quantum Reality
Quantum theorist Christopher Fuchs explains how to solve the paradoxes of quantum mechanics. His price: physics gets personal.
A New Theory to Explain the Higgs Mass
One of the greatest mysteries in physics could be solved by a mattress-like axion field that permeates space and time.
Will Computers Redefine the Roots of Math?
When a legendary mathematician found a mistake in his own work, he embarked on a computer-aided quest to eliminate human error. To succeed, he has to rewrite the century-old rules underlying all of mathematics.
