Akbari1,21<a href='/institutions/NA-North-America/US-United-States/CA-California/261-University-of-California'>Department of Entomology and Riverside Center of Disease Vector Research, Institute for Integrative Genome Biology, University of California, Riverside</a>, 2Section of Cell and Developmental Biology, Division of Biological Sciences, University of California, San DiegoMicroinjection of Nasonia vitripennis embryos is an essential method for generating heritable genome modifications. Described here is a detailed procedure for microinjection and transplantation of Nasonia vitripennis embryos, which will greatly facilitate future genome manipulation in this organism.<h2 class="jove_title"><a href="https://www.jove.com/video/56737">Diffuse Reflectance Spectroscopy: Getting the Capillary Refill Test Under One's Thumb</a></h2>Joakim Henricson1,2, Rani Toll John1,3, Chris D.

Here's a look at what's coming up in the December 2017 issue of JoVE: The World's Premier Video Journal.
From a flurry of fantastic articles for December, we begin with a customizable MRI guided focused ultrasound treatment for patients with essential tremor. In JoVE Medicine, our authors describe patient selection, equipment setup, sonication, and post treatment follow-up. The exciting results show that patients experienced both short- and long-term reductions in their tremors, beginning immediately after treatment.
Next, JoVE Neuroscience loops in to the circulatory system. Here, our authors describe a protocol that uses diffuse polarization spectroscopy to improve the clinical usefulness of the capillary refill test. The capillary refilling response is measured quantitatively using videos, in contrast to traditional methods that rely on visual observation. Compared to naked eye observations, this method allows for more accurate monitoring of circulation in critically injured or ill patients. 
In a gem of an article, from JoVE Developmental Biology, our authors demonstrate a procedure for microinjecting developing jewel wasps Nasonia vitripennis. The test embryos were removed from their parasitized host pupae, and successfully injected with CRISPR/Cas9 molecules. This procedure overcomes significant challenges in working with jewel wasp embryos and will allow future research groups to perform genome modifications in this and similar organisms. 
Our final article heats things up, with laboratory experiments simulating the formation of a lava-phase following a nuclear reactor core meltdown. In JoVE Chemistry, our authors heat real nuclear fuel, cladding, and containment materials to temperatures beyond 3,000 degrees Kelvin. These experiments answer key questions related to core meltdown, and contribute to the prevention of severe accidents in nuclear power plants. That's hot science!
