Tech Xplore / A light-sensitive compound enables heatless membrane modulation in photoswitches

Optical technologies that can be used to modulate neuronal activity are opening up exciting possibilities for research in neuroscience and biology. Optical tools allow neuroscientists to excite and inhibit neurons or areas ...

Phys.org / Compact dark object search: Scanning Earth's core with superconducting gravimeters

Physics theory suggests that the universe is made up in great part by a type of matter that does not emit, absorb or reflect light, and hence cannot be observed using conventional detection methods. This type of matter, referred ...
