Intense laser light modifies the pairing of electrons

The quantum-mechanical exchange interaction between electrons, a consequence of the Pauli exclusion principle, can be specifically modified with intense infrared light fields on time scales of a few femtoseconds, as time-resolved ...

While some insects are declining, others might be thriving

Observations of abundance changes in one group of insects—for example grasshoppers—say very little about how other types of insects, such as flies, are doing, even in the same place. This is because different groups of ...
