However, the ability to target genes using RNAi during pre-adult stages is limited in the major human malaria vector Anopheles gambiae. We describe an RNAi protocol to reduce gene function via direct injection during pupal development.<h2 class="jove_title"><a href="https://www.jove.com/video/54034">Spotting Cheetahs: Identifying Individuals by Their Footprints</a></h2>Zoe C.

2016: This Year in JoVE

Welcome to <a href="http://www.jove.com/">JoVE</a>'s Year in Review, where we highlight some of the most interesting video protocols of the past year.
In January 2016 JoVE started out with a bang...or rather, it didn't need to...as <a href="http://www.jove.com/eng">JoVE Engineering</a> gave us a protocol for the production of <a href="http://www.jove.com/video/53473/production-of-synthetic-nuclear-melt-glass">synthetic nuclear melt glass</a>. This is a valuable tool for forensic study of post-detonation, without the boom.
February was a treasure of a month for JoVE - not only did we publish our 6000th article, but in <a href="http://www.jove.com/chem">JoVE Chemistry</a> we showcased research on <a href="http://www.jove.com/video/53388/a-simple-method-for-size-controlled-synthesis-stable-oligomeric">gold nanoparticles</a> from the laboratory of a Nobel Prize winner.
In March, <a href="http://www.jove.com/biology">JoVE Biology</a> described <a href="http://www.jove.com/video/53738/rnai-trigger-delivery-into-anopheles-gambiae-pupae">RNA interference</a> in the malaria vector Mosquito Anopheles gambiae, through direct pupal injection. This promising research may pave the way for the next generation of mosquito-borne disease control.
April heralded the launch of a new Science Education collection - <a href="http://www.jove.com/science-education/chem">Chemistry</a>. Here, we unveiled protocols covering the fundamentals of general, organic, and Inorganic chemistry - giving students the chance to explore lab techniques, common equipment, and core theories of Chemistry.
Shhh! In May, <a href="http://www.jove.com/enviro">JoVE Environment</a> profiled a novel technique for tracking and <a href="http://www.jove.com/video/54034/spotting-cheetahs-identifying-individuals-by-their-footprints">identifying individual cheetahs</a> from just their footprints...allowing researchers to better monitor and protect Africa's most endangered large Felid.
June gave us the new Science Education <a href="http://www.jove.com/science-education/clinicskills">Clinical Skills</a> collections, providing a foundation for performing physical examinations of patients including the assessment of vital signs, and basic external and internal evaluations.
In July, <a href="http://www.jove.com/neuro">JoVE Neuroscience</a> was buzzing with cool science. We showcased research into the taste <a href="http://www.jove.com/video/54233/a-novel-behavioral-assay-to-investigate-gustatory-responses">perception of honeybees</a> to different nutrients and toxins and how this influences the feeding behavior of these critical pollinators.
<a href="http://www.jove.com/med">JoVE Medicine</a> got to the heart of the matter in August...profiling a new method to help investigate <a href="http://www.jove.com/video/54295/intracoronary-acetylcholine-provocation-testing-for-assessment">angina</a> and identify constrictions in coronary arteries.
September launched three new JoVE Journal sections covering Genetics, Cancer Research, and Biochemistry.These new collections include groundbreaking research into topics as diverse as genetic engineering of unconventional <a href="http://www.jove.com/video/54371/genetic-engineering-an-unconventional-yeast-for-renewable-biofuel">yeast strains for biofuels</a>...mass spectrometry for <a href="http://www.jove.com/video/54420/species-determination-quantitation-mixtures-using-mrm-mass">meat authentication</a>...and mixed cell culture models to mimic <a href="http://www.jove.com/video/54429/a-mimic-tumor-microenvironment-simple-method-for-generating-enriched">tumor microenvironments</a>.
In October, JoVE <a href="http://www.jove.com/i2">Immunology and Infection</a> took us behind the scenes in a Biosafety Level 4 facility. In a four article series, we showed how researchers operate <a href="http://www.jove.com/video/53602/safety-precautions-operating-procedures-an-bsl-4-laboratory-3">aerobiology chambers</a>...use <a href="http://www.jove.com/video/52317/safety-precautions-operating-procedu">safety suits</a> and <a href="http://www.jove.com/video/53600/safety-precautions-operating-procedures-an-bsl-4-laboratory-2-general">biosafety cabinets</a>...and perform <a href="http://www.jove.com/video/53601/safety-precautions-operating-procedures-an-bsl-4-laboratory-4-medical">medical imaging</a> in an environment containing life threatening diseases like the Ebola virus.
November's <a href="http://www.jove.com/behavior">JoVE Behavior</a> explored...um...oh yes...memory.Our authors showed that <a href="http://www.jove.com/video/54790/using-pharmacological-manipulation-high-precision-radio-telemetry-to">turtles</a> actively use memory and recall to find their seasonal habitats, and not simply environmental cues.
Finally, in December, <a href="http://www.jove.com/bioengineering">JoVE Bioengineering</a> helped us to see things more clearly, with a new technique for performing <a href="http://www.jove.com/video/54774/three-dimensional-super-resolution-microscopy-f-actin-filaments">3D super-resolution microscopy</a> of individual cell structures and components.
This Year in Review was just a sampling of more than 1100 video-articles that JoVE published in 2016. Browse the <a href="http://www.jove.com/archive">JoVE archives</a> for thousands of other videos, and come back each week to see brand-new material in <a href="http://www.jove.com">JoVE: The Journal of Visualized Experiments</a>
