Faster Photons Could Make Data Totally Secure
Transferring data using light passed along fiber optic cables has become increasingly common over the past decades, but each pulse currently contains millions of photons. That means that in principle, a portion of these could be intercepted without detection. Secure data is already encrypted, but if an...

Antiferromagnetic-Based Memory Processes Data at Terahertz Speeds
Data travels down fiber-optic cables at frequencies of several terahertz. As soon as the data arrives on a PC or television, this speed must be throttled down to match the data processing speed of the device components; this speed currently is in the range of a few hundred gigahertz...

When it comes to the “smell test,” the nose isn't always the best judge of food quality. Now in a study appearing in ACS’ journal Nano Letters, scientists...
Briefs: Communications
First responders often have trouble communicating with each other in emergencies. They may use different types of radios, they may be working in rural areas lacking wireless coverage, or they may be...
Briefs: Sensors/Data Acquisition
Artificial intelligence (AI) has been used to teach wireless devices to sense people's postures and movement, even from the other side of a wall. RF-Pose uses a neural network to analyze radio...
Briefs: Communications
For wireless networks that share time-sensitive information on the fly, it's not enough to transmit data quickly: that data also needs to be fresh. Consider the many sensors in your car. While it may...
Briefs: Communications
Researchers at NASA's Marshall Space Flight Center have devised a method for the creation of crystal-free non-oxide optical fiber preforms. Non-oxide fiber optics are extensively used in...

Video Distribution & Storage Unit (VDSU)
Engineers at NASA Goddard Space Flight Center’s Satellite Services Projects Division (SSPD) have designed a high-performance, space-qualified video distribution and storage unit for Restore-L, a spacecraft that will rendezvous, grasp, refuel, and relocate client spacecraft. While previous...
Briefs: Manufacturing & Prototyping
Demands for improved computer processing power have led researchers to explore both new processes and other materials beyond silicon to produce electronic components....
Briefs: Materials
Power electronics used for routing, control, and conversion of electrical power traditionally utilize silicon semiconductors. These systems tend to be bulky, require active cooling, and are inadequate for...
Briefs: Automotive
Vanadium dioxide’s unique properties make it ideally suited for outperforming silicon and giving rise to a new generation of low-power electronic devices. This compound can be...
Briefs: Sensors/Data Acquisition
Microphones, from those in smartphones to hearing aids, are built specifically to hear the human voice — humans can’t hear at levels higher than 20 kHz, and microphones max out at...
Briefs: Data Acquisition
Leaders of teams such as first responders must maintain situational awareness to effectively react, coordinate, and respond to circumstances that can often become hazardous. Effective communications...
