One of the major side effects of chemotherapy is a sharp drop in white blood cells, which leaves patients vulnerable to dangerous infections. Chemotherapy patients usually receive a dose every 21 days. After each dose, their white blood cell levels fall and then gradually climb again. Doctors usually only...

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...

For the more than 1 million Americans who live with Type 1 diabetes, daily insulin injections are literally a matter of life and death. And while there is no cure, a new device may help manage the disease.

Space environments are particularly harsh for the high-strength fibers NASA relies on for soft structures. Kevlar, Nomex, Nylon, and other synthetic fibers are broken down by exposure to the combination of vacuum, atomic oxygen, and ultraviolet radiation. Glass fiber offers unique advantages for...

Hot foods are psychologically pleasing. Food heating systems are currently part of the astronaut feeding program. An electrical method of heating foods during dispensing in space uses magnetic induction heating. The process is up to 95% efficient in converting...

Current engines and combustors run at high temperature, which leads to problems of engine knocking, soot and NOx emissions, and difficulty in combustion control. On the other hand, low-temperature combustion and fuel...

Engineers in the NASA Goddard Space Flight Center Instrument Electronics Development Branch have developed a chopper-stabilized auto-zero amplifier capable of amplifying signals with extremely small amplitude originating from a thermopile-based infrared (IR) sensor. The instrument is self-adjusting in that it...

A mobile health technology was developed to monitor and predict a user’s psychological status, and to deliver an automated intervention when needed. The technology uses smart-phones to monitor the user’s location and ask questions about psychological status throughout the day.

Most autonomous vehicles have been tested out in city environments, where tech companies like Google can build intricate 3D maps that lay out the exact position of every lane, curb, off-ramp, and street sign. But what about areas with less definable features, like country roads or a desert? An...

There is plenty of moisture in the air — Professor Swee Ching Tan wants to harvest the humidity and put it to good use.

A reader asks: Will it be the OEMs or the Tier-1 and Tier-2 suppliers who will be purchasing 3D metal printing machines?

Digital technologies are bringing big data, automation, and mobile capabilities to processes like IT, HR, sales, and marketing, but what is the hold-up with product development? Has your product development process been modernized and “digitized?”

Though a flexible solar cell offers exciting, new ways of powering vehicles, clothing, and other smart technologies, manufacturing the photovoltaic component is a challenge.

Simulation tools offer insight into the physical processes of heavy-duty engines. But what about natural wear and tear?

Researcher Jaana Vapaavuori answered an additional question regarding the future of flexible solar cells.

A recent Tech Briefs TV video demonstrated an artificial-intelligence system developed by MIT researchers. The "RF-Pose" teaches wireless devices to sense people's movement, even from the other side of a wall. See the system in action.

Just because it's computer simulation doesn't mean it's virtual prototyping. Our expert explains.
