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 ...
Nearly half of the human genome is composed of genetic parasites—transposons, plasmids, viruses, and other genetic elements that have one thing in common: they don't make any beneficial contributions to their hosts, and ...
(Phys.org)—For the first time, researchers have simulated particles that can spontaneously self-assemble into networks that form geometrical arrangements called Archimedean tilings. The key to realizing these structures ...
In 2002, Secretary of state Donald Rumsfeld made a statement regarding weapons of mass destruction that today is still well known. He famously parsed the evidence (or lack thereof) into "known knowns, known unknowns, and ...
(Phys.org)—As humans, we have a strong sense of fairness that often causes us to go out of our way to punish an unfair person, even when such an action comes at a cost to ourselves. This desire for fairness is epitomized ...

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).
How a new method of inferring ancient population size revealed a severe bottleneck in the human population which almost wiped out the chance for humanity as we know it today.
