Simulations show extreme opinions can lead to polarized groups

In recent years, chaos theory and other forms of computational modeling have sought to leverage findings in the social sciences to better describe—and maybe one day predict—how groups of people behave. One approach looks ...

DNA Lego bricks enable fast rewritable data storage

Do urban fish exhibit impaired sleep?

Melatonin controls the body clock—high melatonin levels make us feel tired in the evening. However, the hormone also plays an important role in animals' biological rhythms. Artificial light at night—light pollution—can ...
