Explanation
This comic features a scientist presenting a newly created molecule to colleagues. The molecule has one end region and two cold regions, and was shaped to produce electric haptic sensations -- essentially, it would cause the sensation of being "gently vibrated." When asked if there's any reason to think it has any practical use, the scientist says "just one" -- and then protests erupt, with people saying "projects like this are a waste of money!" The final panel reveals the punchline: "Does that name... you guys hold on, first let me be in the world's smallest protest" -- implying the molecule is essentially a molecular-scale vibrator. The humor lies in the contrast between the dry, technical scientific presentation and the obvious (but unstated) sexual application of a molecule designed specifically to vibrate pleasantly on contact.
