Cells are dynamic, fast-changing, complex, tiny, and often hard-to-see in environments that don’t always behave in predictable ways when exposed to external stimuli. Now, researchers led by Lukasz Bugaj of the School of Engineering and Applied Science have found new ways to modulate cell activity remotely.
