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 ...
Research led by Duke University, Durham, has discovered a situation-dependent traffic jam in mRNA translation caused by RNA hairpins leading to higher translation of upstream start codons (uAUGs).
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": ...

(PhysOrg.com) -- Swiss scientists have proposed that if robots could evolve through natural selection the result would be robots that would help each other, cooperate, and be capable of hunting. Their experiments follow on ...
New research from the University of Warwick reveals that words like "sex" endure in our language in a "survival of the fittest" way, similar to natural selection.
