A set of cellular biology and molecular-engineering breakthroughs points to faster ways to see—and measure—complex biological systems. EPFL researchers developed CenSpark, a fluorescent probe that illuminates centrioles and cilia in living cells across species, enabling improved visualization of cell division, development, and immunity-related biology. At the imaging and molecular-organs level, EPFL’s work complements other visualization efforts, including high-resolution microscopy approaches that map nanoscale organization in cancer cell nuclei. These tool advances aim to translate previously hard-to-observe structures into tractable experiments for drug discovery. The net effect is incremental but important: better imaging agents and measurement platforms can shorten target validation cycles by clarifying where key processes occur in live systems.
