Nature 2002: "Second law broken. Researchers have shown for the first time that, on the level of thousands of atoms and molecules, fleeting energy increases violate the second law of thermodynamics. [...] They found that over periods of time less than two seconds, variations in the random thermal motion of water molecules occasionally gave individual beads a kick. This increased the beads' kinetic energy by a small but significant amount, in apparent violation of the second law." http://www.nature.com/news/2002/020722/full/news020722-2.html
Scientific American 2002: "Second Law of Thermodynamics Violated. [...] ...the water molecules interacted with the bead in such a way that energy was transferred from the liquid to the bead. These additional kicks used the random thermal motion of the water to do the work of moving the bead, in effect yielding something for nothing. For periods of movement lasting less than two seconds, the bead was almost as likely to gain energy from the water as it was to add energy to the reservoir, the investigators say." https://www.scientificamerican.com/article/second-law-of-thermodynam/
The key fact is the enormous duration of the thermal kick - up to two seconds. You may not know the physical mechanism (in 2002 scientists didn't know it) but there can be no doubt that the second law of thermodynamics is violated - hence the straightforward titles.
I have discussed this and other violations of the second law (which are, surprisingly, commonplace) in my comments here:
Nature 01 November 2017: "The new thermodynamics: how quantum physics is bending the rules. It would take a foolhardy physicist to dare attempt to break the laws of thermodynamics. But it turns out that there may be ways to bend them." http://www.nature.com/news/the-new-thermodynamics-how-quantum-physics-is-bending-the-rules-1.22937
