This afternoon, JoVE was highlighted on PRI’s The World radio broadcast. CEO Moshe Pritsker addressed how science was broken but that sharing methods via video can help alleviate the strain of trying to replicate others’ results. To learn more about what sparked the need for a modern way to communicate scientific methods, you can read the complete article found here.
In this episode, “Ask Adam about Grad School” takes on oral exams, and not the dental kind.
Science’s Entrance into the Age of the “Talkies”
This is a guest post by Adam Ruben, PhD. The opinions expressed are his own.
Scientific journals are great—they communicate technical results, postulate new theories, and help cure insomnia. But the Journal of Visualized Experiments is different. JoVE represents a new breed of scientists, a generation aware that if a picture is worth a thousand words, a video is worth a thousand words plus a pop-up ad.
As we approach the one-year anniversary of JoVE’s 2500th video article, let’s examine the history of scientific results distributed by digital video:

We spend one third of our lives sleeping. “If sleep doesn’t serve an absolutely vital function, then it is the greatest mistake the evolutionary process ever made” – Professor Emeritus Dr. Allan Rechtschaffen, University of Chicago. As a parent I instinctively make sure that my children get enough hours of sleep, but then stay up late working. Turns out I am not doing myself any favors.
Scientists presenting their research at the Society for Neuroscience (SFN) 2012 annual meeting in New Orleans report that even a 20% daily sleep deficit is sufficient for loss in cognitive function, impairs memory and alters the normal behavior of brain cells. According to Ted Abel, University of Pennsylvania, loss of only 20% of daily sleep deprivation impairs spatial memory consolidation. Furthermore, according to Gina Poe, University of Michigan, Ann Arbor, adequate sleep is critical for strengthening incompletely learned memories and integrating the old and new information into a coherent memory. Sleep is necessary for strengthening the synapses for the formation of memories as well as weakening the synapses for “inconsequential” memories, e.g. where you parked your car.
According to Dr. Giulio Tononi, University of Wisconsin, Madison, “Sleep synaptic strength is globally renormalized to a basal level that is energetically sustainable and beneficial for memory and performance. Sleep is the price we pay for plasticity.” He also states that if we are sleep restricted, small parts of our brain may fall asleep even though we think we are completely awake. As a consequence we may make mistakes.
Clearly there are consequences as we continue to burn the midnight oil and surely I should sleep as I have an early morning flight to catch to go back home. Make sure to check out JoVE at booth 143 tomorrow and tell us about your research.
During my time as an undergraduate, I developed a care for the environment and an interest in how science and engineering can help preserve the planet. Oddly enough, my organic chemistry professor was a key influence, as he was involved in spreading the message about green chemistry. Green chemistry is chemistry that, by design, is inherently safer for human health and the environment. All of the students in my classes learned the 12 principles of green chemistry and enacted these through student projects and weekly laboratory experiments. We came to see that by designing and performing our experiments with certain principles in mind, we were able to make less of an impact on the environment, while still learning all about alkenes, alkynes, ketones, and aromatics. By including green chemistry in my chemical education, I learned that you don’t necessarily have to be studying environmental science to make a positive impact on the planet, and that these principles can be applied to many aspects of life.
Reflecting on this now, I not only see how important this perspective is for daily life, but for all of scientific exploration. Both those conducting and reporting all forms of scientific research can make an impact in greening science. In addition to clearly-defined organizations that are using green chemistry for scientific and planet impact, like the WarnerBabcock Institute for Green Chemistry, JoVE plays a key, but not often realized role, in this movement of green science. Hearkening back to the 12 principles of green chemistry, the very first principle is: Pollution Prevention-it is better to prevent waste than treat and clean up waste after it has formed.
