First: in mice, raised on a doxycycline-containing diet. Second: if I've understood correctly, there's no idea about what causes Alzheimer, which would reduce the significance of finding reduced levels of tau. Third: there was physical vibration at 40Hz. This cannot be reproduced with headphones or earplugs, let alone a computer speaker. The experiment used a 12 inch sub-woofer (at undocumented levels, but I assume that the levels for humans must exceed those for mice). 40Hz might not even be suitable for humans if the effect stems from oscillations in the physical brain matter rather than electrical. Four: the number of subjects per condition is very low, and the variance is high. The individual data points can be seen on the graphs, and don't give me much confidence. E.g., 2 mice in the grid hang condition failed immediately, but the other 2 performed in the lower range of the other group. Don't get your hopes up.
