Study reveals how social relationships transform bird flocks
Flocks of birds may appear to move with a single mind, but new research shows jackdaws stick with their mates—even though it harms the flock.

A team of researchers at the University of Tokyo has found that large numbers of pedestrians meeting in crosswalks tend to follow the Lévy walk process. In their paper published in Journal of the Royal Society Interface, ...
Oxygen in the form of the oxygen molecule (O2), produced by plants and vital for animals, is thankfully abundant in Earth's atmosphere and oceans. Researchers studying the history of O2 on Earth, however, know that it was ...

Electrical resistance is a simple concept: Rather like friction slowing down an object rolling on a surface, resistance slows the flow of electrons through a conductive material. But two physicists have now found that electrons ...
