Mathematical Analysis of Fruit Fly Wings Hints at Evolution’s Limits
A painstaking study of wing morphology shows both the striking uniformity of individuals in a species and a subtle pattern of linked variations that evolution can exploit.
To Learn More Quickly, Brain Cells Break Their DNA
New work shows that neurons and other brain cells use DNA double-strand breaks, often associated with cancer, neurodegeneration and aging, to quickly express genes related to learning and memory.
Computer Scientists Discover Limits of Major Research Algorithm
The most widely used technique for finding the largest or smallest values of a math function turns out to be a fundamentally difficult computational problem.
Physicists Create a Bizarre ‘Wigner Crystal’ Made Purely of Electrons
The unambiguous discovery of a Wigner crystal relied on a novel technique for probing the insides of complex materials.
