Researchers at UC San Diego who last year genetically engineered bacteria to keep track of time by turning on and off fluorescent proteins within their cells have taken another step toward the construction of a programmable genetic sensor. The scientists recently synchronized these bacterial “genetic clocks” to blink in unison and engineered the bacterial genes [...]

Romance may happen every day, but finding true love in London is as rare as aliens in the galaxy, says one London-based economist.
Peter Backus, a teaching fellow of economics at the University of Warwick, has calculated that he has a 0.00034 percent chance of finding love in the British capital using the same “Drake” equation [...]

An exotic type of symmetry — suggested by string theory and theories of high-energy particle physics, and also conjectured for electrons in solids under certain conditions — has been observed experimentally for the first time.
An international team, led by scientists from Oxford University, report in a recent article in Science how they spotted the symmetry, [...]
