Laser technology confines light inside a resonator containing a gain medium, a material with quantum properties that can amplify light. As laser resonators are generally far larger than the wavelength of light, lasing inside ...
Earth's complex systems interact between atmospheric, terrestrial, hydrological, cryological (ice and snow) and biological processes in feedback loops. Understanding their relationships is important for modeling their future ...
Researchers have 'hacked' the earliest stages of photosynthesis, the natural machine that powers the vast majority of life on Earth, and discovered new ways to extract energy from the process, a finding that could lead to ...

Darwinian evolution is the process by which natural selection promotes genetic changes in traits that favor survival and reproduction of individuals. How fast evolution happens depends crucially on the abundance of its "fuel": ...

The formation of air bubbles in a liquid appears very similar to its inverse process, the formation of liquid droplets from, say, a dripping water faucet. But the physics involved is actually quite different, and while those ...
