Radiation Analysis Software

For emergencies involving radiation, decision-makers must have a means to swiftly assess the situation. Having analysis tools that can quickly and reliably make sense of radiation data is of the essence.

An acknowledged objective of critical-care medicine is a timely, accurate, readily deployable, cost-effective, and, importantly, safe means of assessing and/or monitoring critical...

NASA Ames Research Center has developed a novel, low-cost, self-contained guidance system for small payload operators. Small satellites are becoming ever more capable of performing valuable missions for both...

Overt symptoms of many diseases often do not manifest until days after a person’s initial exposure to the causative pathogen, typically a virus or bacteria. By then, the disease may...

Plastic Material Works as a Heat Conductor

Plastics are excellent insulators, meaning they can efficiently trap heat — a quality that can be an advantage in something like a coffee cup sleeve. But this insulating property is less desirable in products such as plastic casings for laptops and mobile phones that overheat, in part, because the...

Two-photon lithography (TPL), a high-resolution 3D printing technique, is capable of producing nanoscale features smaller than 1/100 the width of a human hair. The technique could enable X-ray...
