NINscope, a versatile miniscope for multi-region circuit investigations.

Miniaturized fluorescence microscopes (miniscopes) have been instrumental to monitor neural signals during unrestrained behavior and their open-source versions have made them affordable. Often, the footprint and weight of open-source miniscopes is sacrificed for added functionality. Here, we present NINscope: a light-weight miniscope with a small footprint that integrates a high-sensitivity image sensor, an inertial measurement unit and an LED driver for an external optogenetic probe.

Inertial shear force and the impact on facilities for the International Space Station.

Inertial shear force is a surface force that is generated in centrifuges especially with attached samples on flat surfaces and plays a significant role in gravitational and space research. The magnitude of this force is proportional to the radius of the centrifuge and surface area of the sample compartment. In gravitational research we want to study the impact of weight onto a system.

Microgravity and bone cell mechanosensitivity.

The capacity of bone tissue to alter its mass and structure in response to mechanical demands has long been recognized but the cellular mechanisms involved remained poorly understood. Bone not only develops as a structure designed specifically for mechanical tasks, but it can adapt during life toward more efficient mechanical performance. Mechanical adaptation of bone is a cellular process and needs a biological system that senses the mechanical loading.
