'Classic example' of sexual dimorphism in fossil record actually shows nuance between males and females

For decades, paleontologists have held up uintatheres as a prime illustration of sexual dimorphism, or the tendency for males and females of a species to be physically different. Notable for their large size, prominent horns ...

One quantum material, two superconducting states: Stretching helps explain conflicting experiments

Unconventional superconductors can host unusual electronic states, but understanding what drives their superconductivity becomes difficult when different forms of order coexist. The kagome metal CsV3Sb5 has become a particularly ...
