Since 2006, JoVE has brought high quality video articles to the biological sciences community. Currently, JoVE publishes high quality scientific video protocols in the areas of neuroscience, general biology, bioengineering, immunology and infection, clinical and translational medicine, and applied physics.

Today, February 4, 2013, JoVE proudly launches its 7th section: JoVE Chemistry. Following its successful introduction of video publications for the biological and physical sciences, JoVE received numerous requests for a chemistry counterpart. In response, the journal is launching a new section, JoVE Chemistry dedicated to visualized publication of experiments across different areas of chemistry research including organic chemistry, chemical biology, electrochemistry, and polymer chemistry, among others. Check out our Chemistry announcement here:

“Similar to research in biology and physics, experimental research in chemistry suffers from a lack of reproducibility that can be solved by visualized publication. Therefore, it is natural to expand JoVE‘s novel publication approach to chemistry as well”, says Moshe Pritsker, the CEO and co-founder of JoVE.

Today marks an important day in JoVE’s history. Today JoVE, The Journal of Visualized Experiments, published two articles in partnership with the United States government’s Defense Threat Reduction Agency (DTRA). JoVE is proud to present the work from Temple University’s Dr. Chris Schafmeister and State University of New York Buffalo’s Dr. David Pawlowski and Dr. Richard Karalus.

The support of scientists conducting research for DTRA has significant ramifications for identifying, treating, and preventing the outbreak of defense threats. DTRA exists to safeguard America and its allies from weapons of mass destruction (WMD), including chemical, biological, radiological, nuclear weapons and high-yield explosives (CBRNE), by providing capabilities to reduce, eliminate, and counter the threat and mitigate its effects. Because the techniques and technologies developed in DTRA sponsored laboratories promise a safer world and will benefit from distribution in a highly visual format, DTRA has sponsored the research and publication of their scientists in JoVE.

JoVE Judo in Science NOW

On Tuesday, JoVE published a fascinating article on how energy is used during complex sports, such as judo and other martial arts. Previous research on exercise science has focused on sports that can be easily recreated in the lab, such as running and cycling, but these Brazilian scientists have found a completely unique way of studying more complex sports.

Science NOW picked up the story and did an excellent job of explaining how the researchers did it:

The Science of Judo

Martial arts are exhausting, as anyone who’s traded a few punches, kicks, or throws can attest. But where exactly does the energy come from? Every form of exercise uses a different combination of the body’s metabolic systems for energy. Cyclical sports such as running and cycling are relatively easy to replicate with exercise machines in a laboratory, but that’s harder to do with more unpredictable sports such as martial arts. So a team of Brazilian researchers have taken the lab into the dojo to study the energy requirements of the Japanese art of judo.

Three different systems convert food to energy. During long periods of moderate exercise, aerobic metabolism does most of the work, using oxygen to turn sugar into energy, water, and CO2. Running a marathon or cycling for 100 miles, therefore, is almost entirely aerobic. For shorter, more intense exertion, or when the oxygen runs out, muscles can break down sugar anaerobically, although that system is far less efficient and produces muscle-burning lactic acid as a byproduct. Lastly, for very short bursts of energy, such as a 10-second sprint, muscles can rely on another type of anaerobic system: they use up energy-storing compounds, called phosphagens, in muscular tissues.

JoVE Makes an Impact in Canada

As many of you know, JoVE appeared on CTV National News this past weekend. Though JoVE was founded in and operates out of Cambridge, MA we are an international journal, with video-articles published from 35 countries, including over 100 articles from researchers across Canada.

The CTV news story did an excellent job of explaining why this is so significant. Despite the huge advances in scientific innovation, academic publishing has barely changed in the past 300 years. JoVE is the world’s only peer reviewed, PubMed-indexed journal publishing all of its content in both text and video format. This makes research more accessible, and easier to teach, learn and understand.

Scientists Upload Research to YouTube-Inspired Journal

A science journal that broke the mold of academic publishing with a YouTube-inspired approach to sharing new studies is celebrating its fifth year with a growing Web audience.

The Journal of Visualized Experiments, or JoVE, is an online, peer-reviewed and indexed scientific journal that highlights the latest research on everything from plankton cells to human diseases.

What makes JoVE different from some 25,000 scientific journals published worldwide is that it presents information in video format. Subscribers can watch scientists perform and discuss experiments, show off new lab techniques and browse through microscope slides.

Jellyfish Strokes Come To Life With Laser Vision

New Scientist TV posted a new video explaining how an underwater laser imaging device makes it possible to study jellyfish in their natural environment.

SCUVA was developed by Dr. Kakani Katija Young and Dr. John Dabiri to study the effect of jellyfish and other organisms on ocean mixing. The technique was published in the October issue of JoVE and can be found here.

A night dive isn’t usually ideal for spotting marine life, unless you’re using a new underwater laser imaging device. The SCUVA system shown in this video, developed by bioengineers Kakani Katija of the Woods Hole Oceanographic Institution in Falmouth, Massachusetts and John Dabiri from the California Institute of Technology, works best in darkness. In this clip, it’s being used to visualise the wake produced by jellyfish.

The device was developed by adapting technology used in the lab for open waters. After finding a good subject, a diver observes exhaled bubbles to determine the overall current.  Suspended particles are then illuminated by a laser, so that a high-definition camera can capture how they move. Later, a computer programme uses the video to track the particle motion and deduce the flow around the animal.

The system is allowing researchers to better investigate marine animal behaviour, as well as their natural environment. Collaborator Sean Colin of Roger Williams University is currently using the device to study how invasive comb jellyfish use a delicate feeding current to sneak up on prey. The unique camera could also be used to help determine the effect of migrating sea organisms on ocean mixing.

Last Friday, Kalliopi Monoyios  featured research in JoVE on her Scientific American blog, Symbiartic.

Though her blog generally focuses on the intersection between science and art, our SCUVA experimental video was so visually compelling, it fit right in with the rest of her posts.

I Heart Copepods. You should, too.

Dr. Kakani Katija and her colleagues published a paper this week in JOVE that shows off a cool new device they’ve developed to record fluid motion caused by the movements of animals in their native habitats using a laser and a hand held video recording device they’ve dubbed SCUVA (self-contained underwater velocimetry apparatus). The device illuminates particles in the water and records their motion as an animal moves through the field of view. The video footage can then be plugged into software that tracks each particle’s movement, creating a neat diagram of vectors around the traveling organism. The device is particularly significant because it allows data to be collected in situ rather than in a lab where native conditions and behavior are difficult if not impossible to recreate. The resulting stills are visually intriguing, but the video clips contained in the author interview are even better.

On Monday our CEO, Moshe Pritsker, went to Harvard University to demonstrate JoVE at an “eScience” workshop co-hosted by Microsoft.

The workshop featured live demonstrations of 20 technologies that could enhance scientific research. The Harvard Crimson covered the workshop and focused on JoVE:

“eScience” Is New Frontier

“We think the traditional paper-format research publication is very unproductive,” Pritsker said.

“People can get lost reading the content they are not familiar with,” he said.

Pritsker said the platform has three parts—introduction, animation and experimental procedures—corresponding to the abstract, experimental design, description of the results, and other components found in a conventional research paper. With JoVe, scientists can more easily communicate temporal aspects of their results, such as change in a given metric over time—a result integral to many life science experiments.

“We think JoVe can overcome the inherent limitations of traditional, static print journals, thereby adding an entirely new parameter to the communication of experimental data and research results,” Pritsker said.

We are pleased to announce that Thomas Jefferson High School for Science and Technology is the first post-secondary school to subscribe to JoVE.

Though JoVE  has video articles showing basic experimental procedures, the majority of the content showcases cutting edge technology out of Ivy League schools— not the level of research one would usually associate with the high school curriculum.

“We’re just not your typical high school,” explains Dr. Andrea Cobb, Lab Director at Jefferson, listing off some of their equipment, “we have a DNA sequencer, mammalian cell culture facilities, we just got environmental growth culture facilities. We have a lot of toys. Stuff I didn’t even have when I was in grad school.”

Dr. Cobb, who teaches both biotechnology and microbiology at Jefferson, requested a subscription to JoVE because she thinks it will help her students learn to use the schools advanced equipment.

“This way they can see a procedure and practice it over and over again,” she said. “A picture is worth a thousand words and a video is worth a thousand teachers.”
