Monitor Detects White Blood Cell Levels
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...

Auto-Zero Differential Amplifier
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...

Polymer-Based 2D-to-3D Transformable Surfaces
Technologies using stretchable materials are increasingly important. Yet, in general, it is not possible to control how they stretch with much more sophistication than inflating balloons. A method was developed that allows the calculated transformation of 2D stretchable surfaces into targeted 3D shapes.
