Life With Longer Genetic Codes Seems Possible — but Less Likely
Life could use a more expansive genetic code in theory, but new work shows that improving on three-letter codons would be a challenge.
Newly Measured Particle Seems Heavy Enough to Break Known Physics
A new analysis of W bosons suggests these particles are significantly heavier than predicted by the Standard Model of particle physics.
Mitochondria Double as Tiny Lenses in the Eye
The optical properties of mitochondrial bundles in the retina may improve how efficiently the eye captures light.
Father-Son Team Solves Geometry Problem With Infinite Folds
The result could help researchers answer a larger question about flattening objects from the fourth dimension to the third dimension.
Dennis Sullivan, Uniter of Topology and Chaos, Wins the Abel Prize
The American mathematician invented entire new ways to understand shapes and spaces.
A New Tool for Finding Dark Matter Digs Up Nothing
Physicists are devising clever new ways to exploit the extreme sensitivity of gravitational wave detectors like LIGO. But so far, they’ve seen no signs of exotica.
An Antimatter Experiment Shows Surprises Near Absolute Zero
An experiment conducted on hybrid matter-antimatter atoms has defied researchers’ expectations.
Machine Learning Reimagines the Building Blocks of Computing
Traditional algorithms power complicated computational tools like machine learning. A new approach, called algorithms with predictions, uses the power of machine learning to improve algorithms.
Math’s ‘Oldest Problem Ever’ Gets a New Answer
A new proof significantly strengthens a decades-old result about the ubiquity of ways to represent whole numbers as sums of unit fractions.
