Science News: To mask data transferred between a sender and a receiver, researchers have developed a cloaking device that creates holes in time and space. Joseph Lukens of Purdue University in West Lafayette, Indiana, and colleaguesâmdash;whose paper was published online in Natureâmdash;manipulated the flow of photons so that minute gaps occurred in the light wave. They then injected an electrical signal, consisting of binary data, that went undetected because the data bits passed through the gaps. Such a device could advance the field of secure communications by concealing transmissions from potential eavesdroppers.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
