This small device developed at Los Alamos National Laboratory uses the truly random spin of light particles as defined by laws of quantum mechanics to generate a random number for use in a cryptographic key that can be used to securely transmit information between two parties. Quantum key distribution represents a foolproof cryptography method that may now become available to the general public, thanks to a licensing agreement between Los Alamos and Whitewood Encryption Systems, LLC. Los Alamos scientist developed their particular method for quantum cryptography after two decades of rigorous testing inside of the nation's premier national security science laboratory.

This image was created using data from the Relativistic Electron-Proton Telescopes on NASA's twin Van Allen Probes. It shows the emergence of a new third transient radiation belt. The new belt is seen as the middle orange and red arc of the three seen on each side of the Earth.

NASA's Mars rover Opportunity captured this view southward just after completing a 338-foot (103-meter) southward drive, in reverse, on Aug. 10, 2014.

On the nano assembly line, tiny biological tubes called microtubules serve as transporters for the assembly of several molecular objects.

A new research platform uses a laser to measure the "nanomechanical" properties of tiny structures undergoing stress and heating, an approach likely to yield insights to improve designs for microelectronics and batteries. Clockwise from upper left, graphics of the instrument setup, and at bottom right a scanning electron microscope image of the tiny silicon cantilever used in the research.

NASA's C-20A Earth science research aircraft with the UAVSAR slung underneath its belly lifts off the runway at Edwards Air Force Base on a prior radar survey mission.

Tunable spin Hall angle device based on GaAs through field induced intervalley repopulation

Cortex regions that showed increased connectivity with a part of the brain’s memory hub (left), or hippocampus (red arrow), following magnetic stimulation at sites over the left parietal cortex (blue arrow). Researchers linked improved performance on an associative memory task to the boost in connectivity.

This image proves that Nf-Trip suppresses tumor growth of HCC orthotopic model.
