Physicists add amplifier to quantum communication toolbox

Quantum encryption using single photons is a promising technique for boosting the security of communication systems and data networks, but there are challenges in applying the method over large distances due to transmission ...

Turning the volume of gene expression up and down

Gene expression can be turned on and off like a switch, or it can be finely adjusted , as with a volume control knob. Dr Garth Ilsley, research scientist in Prof. Nick Luscombe's unit at the Okinawa Institute of Science and ...

An equation to describe the competition between genes

In biology, scientists typically conduct experiments first, and then develop mathematical or computer models afterward to show how the collected data fit with theory. In his work, Rob Phillips flips that practice on its head. ...

Simple mathematical formula describes human struggles

Would you believe that a broad range of human struggles can be understood by using a mathematical formula? From child-parent struggles to cyber-attacks and civil unrest, they can all be explained with a simple mathematical ...

Experimental mathematics: Computing power leads to insights

In his 1989 book "The Emperor's New Mind", Roger Penrose commented on the limitations on human knowledge with a striking example: He conjectured that we would most likely never know whether a string of 10 consecutive 7s appears ...

Researchers develop algebraic model to monitor cellular change

Researchers at New York University's Courant Institute of Mathematical Sciences have developed a novel algebraic model of DNA "hybridization," a process central to most biotechnology devices that monitor changes in cell's ...
