Making quantum cryptography truly secure

Quantum key distribution (QKD) is an advanced tool for secure computer-based interactions, providing confidential communication between two remote parties by enabling them to construct a shared secret key during the course ...

The physics of animation

From drawings to computer animation, the magic of cartoon movies allows audiences to explore a fantastical and imaginary world. To make animated characters life-like on the big-screen, the laws of physics have to be taken ...

For computer chip builders, only one way to go: Up

In the race to build a faster computer chip, there is literally nowhere to go but up. Today's chip surfaces are packed with the tiniest electronic switches the laws of physics allow, but Intel Corp. says it is blowing past ...

Fire ants assemble as a 'super-organism' (w/ video)

The ants may go marching one by one, but they end up forming a superstructure of thousands -- and together they can form a raft that stretches the boundaries of the laws of physics, according to new research released today. ...

Dynamic systems in living cells break the rules

There is considerable interest in understanding transport and information pathways in living cells. It is crucial for both the transport of, for example, medicine into cells, the regulation of cell life processes and their ...

Best yet test of Lorentz invariance

The more crucial a physical law is, the more important it is to keep testing it. One of the most important laws formulated in the last century or so is Albert Einsteinэs principle of invariance, which says that there ...

Bringing down the electric grid

Last March, the U.S. Congress heard testimony about a scientific study in the journal Safety Science. A military analyst worried that the paper presented a model of how an attack on a small, unimportant part of the U.S. power ...
