Synthetic genetic clock keeps accurate time across a range of temperatures Posted: 04 Apr 2014 11:04 AM PDT A long-standing challenge in synthetic biology has been to create gene circuits that behave in predictable and robust ways. Mathematical modeling experts and experimental biologists have now created a synthetic genetic clock that keeps accurate time across a range of temperatures.

New algorithm aids in both robot navigation and scene understanding Posted: 04 Apr 2014 11:03 AM PDT Suppose you're trying to navigate an unfamiliar section of a big city, and you're using a particular cluster of skyscrapers as a reference point. Traffic and one-way streets force you to take some odd turns, and for a while you lose sight of your landmarks. When they reappear, in order to use them for navigation, you have to be able to identify them as the same buildings you were tracking before -- as well as your orientation relative to them. A new algorithm for determining the orientation of objects could aid robots in navigation, scene understanding.

New study on the crime risk on London Underground Posted: 04 Apr 2014 11:00 AM PDT A criminologist who has been working closely with authorities in London to cut crime on one of the world's busiest transport systems will appear before a House of Commons select committee to describe his findings.  Dr Andrew Newton is also forming links with overseas experts so that their research can make public transport systems around the world safer places to travel.
