Researchers from Martin Luther University Halle-Wittenberg (MLU) and the Max Planck Institute of Biophysical Chemistry in Göttingen haben developed nano-sized probes that can measure temperature differences in living cells. These probes enable scientists to better understand how cells produce heat and how this impacts cellular processes. These first response differences inside cells help scientists better understand how heat production happens and how it's regulated in living systems, opening new avenues for research on cellular processes that involve temperature changes such as fever, inflammation, and even cancer development.
