Meet the hybrid micro-robot: The tiny robot that is able to navigate in a physiological environment and capture targeted damaged cells      (via sciencedaily.com) 

Researchers have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms -- electric and magnetic. The micro-robot is able to navigate between different cells in a biological sample, distinguish between different types of cells, identify whether they are healthy or dying, and then transport the desired cell for further study, such as genetic analysis.

New type of entanglement lets scientists 'see' inside nuclei      (via sciencedaily.com) 

Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement between dissimilar particles -- something rare in quantum studies.

Visualizing spatial distribution of electric properties at microscales with liquid crystal droplets      (via sciencedaily.com) 

Existing sensor probes for microelectrical devices can measure only their average electric properties, providing no information on their spatial distribution. Liquid crystal droplets (LCDs) -- microscopic droplets of soft matter that respond to electric field -- are promising in this regard. Accordingly, researchers recently visualized the electric field and electrostatic energy distribution of microstructured electrodes by recording the motion of LCDs under an applied voltage, making for high detection accuracy and spatial resolution.

New invention: The oxygen-ion battery      (via sciencedaily.com) 

An oxygen-ion-battery has been invented, based on ceramic materials. If it degrades, it can be regenerated, therefore it potentially has an extremely long lifespan. Also, it does not require any rare elements and it is incombustible. For large energy storage systems, this could be an optimal solution.

Imaging the proton with neutrinos      (via sciencedaily.com) 

The interactions of the quarks and gluons that make up protons and neutrons are so strong that the structure of protons and neutrons is difficult to calculate from theory and must be instead measured experimentally. Neutrino experiments use targets that are nuclei made of many protons and neutrons bound together. This complicates interpreting those measurements to infer proton structure. By scattering neutrinos from the protons that are the nuclei of hydrogen atoms in the MINERvA detector, scientists have provided the first measurements of this structure with neutrinos using unbound protons.
