Chemistry Solutions: Capturing Multi-Step Syntheses With Video

51039 Miller Urey Origin of Life on Earth Experiment

Editor’s Picks! Associate editor, Emily Watershighlights four videos demonstrating JoVE’s effectiveness in communicating classic and complex Chemistry.

Emily Waters JoVE ChemistryWaters: The chemistry section launched last year, and so I wanted to highlight a range of what we have. I’ve picked a couple traditional chemistry methods and two newer techniques. I think these videos are all pretty cool, and they show the range of what JoVE videos can capture.

800+ Institutions Have Contributed to JoVE. How Does Yours Compare?

JoVE Contributing Institutions Map

Putting JoVE’s contributing institutions on the map.

Here’s a glimpse at an often overlooked feature of JoVE—our map of contributing institutions! We take pride in the breadth and diversity of our content and contributors, and this map visualizes the scale and range of those contributions.

As of this post, we have content from institutions in 47 U.S. states, more than 40 countries, and six continents. (Our videos have even featured footage filmed in Antarctica, although none of our contributing institutions are based there.) Read more…

From Bench to Bedside: Translational Research Trends

50475 A Modified Heterotopic Swine Hind Limb Transplant Model for Translational Vascularized Composite Allotransplantation (VCA) Research

Editor’s Picks! Senior science editor, Dr. Nandita Singh, shares four of her favorite videos from our Clinical and Translational Medicine section.

Clinical and Translational Medicine

Dr. Singh: The development of clinical therapies has not kept pace with the explosion in basic research. In the past decade, however, many in vivo and in vitro animal models have been developed to translate basic scientific research into clinical therapeutics. Thanks to these models, patients are closer to benefitting from the discoveries made in the field of biomedical research. These models range from regenerative therapeutics, cancer cures to organ transplant.

Muscle Function, Cognitive Decline and Aging—This month in JoVE!

This Month In JoVE February 2014

Don’t miss this sneak-preview highlighting the novel research techniques coming your way this month in JoVE!

In this short video, we explore behavioral genetics with a modified 1970s Drosophila flight assay; examine muscle function in aging and dystrophia in terms of “calcium sparks“; share a novel method for developing new treatments for voice and speech disorders by way of lab-borne polyps; and more.

JoVE Saves a Michigan State Lab Thousands

Carrie Northcott Michigan State

“Traditionally all surgical techniques have been passed down from person to person. And it hasn’t been until JoVE and others that they’ve been able to be videotaped and shared.” – Dr. Carrie Northcott

The Problem — While at Michigan State University (MSU), before publishing in JoVE, Dr. Carrie Northcott decided to film a surgical technique she had learned as a post-doctoral student for her lab. That technique, catheter implantation, had proven itself to be a frustrating procedure for her students to learn—even after watching her demonstrate it first hand. “Without a video or anything we’ve had variable success rates,” said her colleague, Core Research Facilities Manager, Brian Jespersen, “Often they can be below 40%.”  Dr. Northcott hoped that her homemade video would address her reproducibility problem by allowing her students to repeatedly watch the procedure.

Environmental Scientists, Feast Your Eyes

JoVE Environment

In this weeks Editor’s Picks collection, associate editor of JoVE’s Environment section, Elizabeth Sheeley, tells us how she developed her passion for environmental science and highlights four of her favorite videos from her section.

Why study environmental science? For Sheeley, it all began with a denitrification research project she did during her undergraduate studies on Plum Islands in eastern Massachusetts—a large ecological study site where scientists research the effects of nutrient loading. Read more…

Investigating the Origins of Life

Miller-Urey experiments study the abiotic synthesis of organic compounds by creating an environment similar to that of the early earth. An electric discharge is applied to a mixture of gases representing the early earth’s atmosphere and lightening. This is done in the presence of a liquid water reservoir, representing the early oceans, as well as with an apparatus simulating evaporation and precipitation.

JoVE introduces a 21st century adaptation of the Miller-Urey origin of life experiments.

Earlier this week, we published a modern approach to the famous 1953 experiment by Dr. Stanley Miller (then a graduate student at the University of Chicago) and Dr. Harold Urey that explored one of the most intriguing research questions facing scientists today—the origin of life on earth. Read more…
