The second law of thermodynamics delineates an asymmetry in how physical systems evolve over time, known as the arrow of time. In macroscopic systems, this asymmetry has a clear direction (e.g., one can easily notice if ...
Depriving a zebrafish of food for six days boosts its chances of winning a fight against a well-fed fish because starvation activates a certain pathway in its brain, neuroscientists at RIKEN have shown. This finding could ...
