Terahertz technology is an emerging field that promises to improve a host of useful applications, ranging from passenger scanning at airports to huge digital data transfers. Terahertz radiation sits between the frequency bands of microwaves and infrared radiation, and it can easily penetrate many materials,...

University of Utah researchers developed a high-speed camera system that spent the past two winters photographing snowflakes in 3D as they fell – and they don’t look much like those perfect-but-rare snowflakes often seen in photos. NASA and the U.S. Army helped fund development of the camera,...

Purdue University researchers have created a new tool to detect flaws in lithium-ion batteries as they are being manufactured, a step toward reducing defects and inconsistencies in the thickness of electrodes that affect battery life and reliability. The electrodes, called anodes and...

NASA, the U.S. Agency for International Development (USAID), the U.S. State Department and Nike have issued a challenge to identify 10 game-changing innovations that could enable fabric systems to enhance global economic growth, drive human prosperity and replenish the planet's resources.

The X-47B Unmanned Combat Air System demonstrator (UCAS-D) completed its first ever carrier-based catapult launch from USS George H.W. Bush off the coast of Virginia. The unmanned aircraft launched from the deck, executed several planned low approaches to the carrier, and safely...

Researchers at the U.S. Naval Research Laboratory flew their fuel-cell-powered Ion Tiger unmanned aerial vehicle (UAV) for 48 hours and 1 minute using liquid hydrogen fuel in a new, NRL-developed, cryogenic fuel storage tank and delivery system. This flight shatters their previous record of...

Advanced biofuels – liquid fuels synthesized from the sugars in cellulosic biomass – offer a clean, green and renewable alternative to gasoline, diesel and jet fuels. Bringing the costs of producing these advanced biofuels down to competitive levels with petrofuels, however, is a major...

Researchers at NASA's Langley Research Center in Virginia are studying ways to prevent the remains of insect impacts from adhering to the wing of an aircraft in flight. The research is serious, and positive results could help NASA's aeronautical innovators achieve their goals for improving...

Scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have reported the first fully integrated nanosystem for artificial photosynthesis. While “artificial leaf” is the popular term for such a system, the key to this success was an...

A new design tool interprets gestures, enabling designers and artists to create and modify three-dimensional shapes using only their hands as a "natural user interface," instead of keyboard and mouse.

NASA scientists are currently working on the first practical field test toward proving the possibility of warp drives and faster-than-light travel. Thanks to a loophole in the theory of relativity, a ship could theoretically travel in such a way that the universe moves around it, allowing it to reach faraway planets very...

Scientists recently unveiled a new genre of tiny, biocompatible electronic devices that could be implanted into the body to relieve pain or battle infection for a specific period of time, and then dissolve harmlessly. These “transient electronics,” described at a meeting of the...

NASA is one of the top research entities in the world, producing technologies that range from electronics and new materials, to state-of-the-art robotics and sensors. Readers of NASA Tech Briefs get a firsthand look at these new technologies every month. But how many of you have had the chance to go behind the scenes at...

If quantum computers are ever to be built, qubits will have to be made more robust and more numerous. Qubits, the quantum equivalent of the bits used in conventional computers, can easily lose their orientation in a process called decoherence when confronted with a noisy environment....

Engineers at NASA's Ames Research Center and amateur radio operators around the world collaborated to reconstruct an image of Earth sent to them from three smartphones in orbit. The joint effort was part of NASA's nanosatellite mission, called PhoneSat.

Researchers at MIT and Sandia National Laboratories have used transmission electron microscope (TEM) imaging to observe, at a molecular level, what goes on during a reaction called oxygen evolution as lithium-air batteries charge. The reaction is thought to be a bottleneck limiting further...

Robots can continually discover and refine their understanding of objects, say researchers at Carnegie Mellon University’s Robotics Institute. The Lifelong Robotic Object Discovery (LROD) process, developed by the research team, enabled a two-armed, mobile robot to use color video, a Kinect depth camera, and...

Scientists of the Max Planck Institute for Evolutionary Anthropology and the Senckenberg Research Institute in Frankfurt, together with dental technicians, have digitally analyzed modern human teeth using finite element analysis to evaluate the biomechanical behavior of teeth under...

Sandia National Laboratories researchers Lisa Deibler and Arthur Brown had a ready-made problem for their computer modeling work when they partnered with the National Nuclear Security Administration’s Kansas City Plant (KCP) to improve stainless steel tubing that was too hard to meet...

A team of researchers at the San Diego Supercomputer Center (SDSC) and the Department of Electronic and Computer Engineering at the University of California, San Diego, has developed a highly scalable computer code that promises to dramatically cut both research times and...

As consumers increasingly use cheaper, smaller tablets and smartphones, a recent IDC report showed that PC sales are down 14% year over year, and Apple's desktop sales are flat. PCs are still more powerful than competing computing devices, and still have a prominent role in the enterprise, but...

Using bundles of vertical zinc oxide nanowires, Georgia Tech researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense...
