Physical systems evolve at a particular speed, which depends on various factors including the system's so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that ...
Deep inside all matter in the universe, electrons are buzzing around and behaving as if they are twirling around on their axes like spinning tops. These "spinning" electrons are fundamental to quantum physics and play a central ...

The transport of mercury ions across intestinal epithelial cells can be studied for toxicology assessments by using animal models and static cell cultures. However, the concepts do not reliably replicate conditions of the ...
How would our world be viewed by observers moving faster than light in a vacuum? Such a picture would be clearly different from what we encounter every day. "We should expect to see not only phenomena that happen spontaneously, ...
