A readers asks two 3D-printing veterans: "What is your advice to someone starting out with additive manufacturing?"

Energy demands are increasing as consumer, industrial, and data communications markets require greater power distribution.

The most dense solid-state memory ever created could soon exceed the capabilities of current computer storage devices by 1,000 times using a new technique. The same technology was used to manufacture atomic-scale circuits, allowing for quickly removing or replacing single hydrogen atoms. The technology...

In recent years, anti-penetration materials have been more widely used for armor, bulletproof vests, and micrometeoroid and orbital debris protection layers for space-suits, space vehicles, and structures....

A compact and portable system is used to monitor and store real-time measurements of stray energy through a pyrotechnic firing circuit using infrared technology. The infrared sensor is mated to the NASA Standard Initiator simulator, and is calibrated such that the current input through the...

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...

Mars is the ultimate destination for NASA's human exploration program. In Situ Resource Utilization (ISRU) is a key technology required to enable such missions. The goals of using resources available at the exploration site are to reduce launch and delivered mass, reduce risk and cost, enable...
