(55958)
We all fawned over this protocol in the <a href="https://www.jove.com/video/56059/protocol-for-assessing-relative-effects-environment-genetics-on">August</a> issue of JoVE <a href="https://www.jove.com/journal/environment">Environment</a>. Here, our researchers relocated wild white-tailed deer to controlled habitats to examine the effects of environment and genetics on development. (56059)
In <a href="https://www.jove.com/video/56288/a-test-bed-to-examine-helmet-fit-retention-biomechanical-measures">September</a>, JoVE Science Education continued its impressive growth trajectory and released 5 new collections covering topics in <a href="https://www.jove.com/science-education/chem">Chemistry</a> and Biology. Over in the video journal, our authors in JoVE <a href="https://www.jove.com/journal/bioengineering">Bioengineering</a> gave us a smashing protocol for simulating high speed collisions with bicycle helmets. (56288) 
Then, JoVE <a href="https://www.jove.com/journal/neuroscience">Neuroscience</a> got a move on in <a href="https://www.jove.com/video/56402/automated-gait-analysis-in-mice-with-chronic-constriction-injury">October</a> with an automated gait analysis for mice with nerve injuries. Here, our authors had mice strut their stuff on a glass runway to illuminate their footprints for the camera. (56402)
During <a href="https://www.jove.com/video/56591/wind-tunnel-experiments-to-study-chaparral-crown-fires">November</a>, JoVE <a href="https://www.jove.com/journal/engineering">Engineering</a> really turned up the heat as our authors described wind tunnel experiments that simulate forest fires in chaparral shrubs. (56591)
Finally, in <a href="https://www.jove.com/video/54807/laser-heating-radiance-spectrometry-for-study-nuclear-materials">December</a> JoVE finished the year with a bang. Not only did we publish our 7,000th video but in JoVE <a href="https://www.jove.com/journal/chemistry">Chemistry</a> our authors showcased laboratory experiments designed to simulate a nuclear reactor core meltdown and improve the safety of nuclear power plants - that's actually pretty cool.
