Our human history is measured in a sequence of “epochs”, periods of time defined by events or advancements. Today, we are entering the epoch of climate change. In this era, Lindsay Graham acknowledges that climate change is real and humans are causing it. Conversations finally turn away from “Do we need to do anything?” to “What are we going to do now?”
This question terrifies conservative political parties across the globe. “What are we going to do now?” cannot be answered by old techniques aging politicians are comfortable with. The beginning of the climate change epoch is the end of their political/economical relevance just as the DVR was the death of Laser Disc. We cannot save our economies and address these new challenges by using strategies developed 30+ years ago during a completely different environment. (more…)

Many of the U.S. state-level shark fin bans which make it illegal to buy, sell, or possess shark fins include exemptions for smooth and spiny dogfish, i.e. by far the most common species of sharks caught by U.S. fishermen. Some of these fisheries have significant conservation concerns associated with them. Much of this fishing is not currently subject to catch limits or other basic management
You would never know that most locally caught sharks are not affected at all by fin bans by reading most of the action alerts that some conservation organizations send out to encourage ocean lovers to support these laws, by following most of the media coverage of these laws, or by reading most people’s excited posts after these laws pass. Many of these inaccurately say that shark fin bans “protect all sharks.”
I have a request to make to the conservation organizations supporting these laws, journalists covering them, and the shark and ocean lovers celebrating when they pass. If you want to support laws with an exemption for dogfish sharks, that’s fine, but let’s have an open and honest discussion about why you are doing this instead of just acting like it isn’t happening.

So you’ve just spent the last few years of your life working on your research project, and now in front of you, you have the final thesis, all smartly bound with a rather dashing cover that would not look out of place in Mr Darcy’s library, with your thesis title and your name glistening in silver or gold lettering. You have a sense of achievement. It has been a difficult labor, but finally your baby has been born, and you cradle it in your arms lovingly as you walk it to the library, and hand over your precious bundle of academic joy to the librarian. They take it from you and head back to the dusty shelves where theses of thousands of past graduate students have accumulated, the place where your dissertation will go to…to die.

North Carolina is well known for both its distinctive barrier islands (making Pamlico Sound the largest lagoon in the U.S.) and highly productive fisheries. Both of these features exist in large part because North Carolina sits that the point where two of the largest ocean currents in the Atlantic meet. From the north, the Labrador Current meanders from the Arctic Circle along the Canadian, New England, and Mid-Atlantic shorelines and crashes into the Gulf Stream at Cape Hatteras, deflecting this warm current off its own shore-hugging course from the south and out across the Atlantic Ocean. Aside from literally defining the shape of the Outer Banks, the collision zone represents the boundary between temperate waters to the north and subtropical waters to the south. This presence of this border means that, depending on the time of year and local weather conditions, you can catch just about any marine fish native to the Northwest Atlantic Ocean off of the Outer Banks.

Author’s note: The following blog post is an adaptation of a professional development training workshop that I gave to our lab’s interns. It is intended to serve as an introductory guide for advanced undergraduate and beginning graduate students who have never published a scientific paper before. It’s a combination of advice I’ve received from teachers, colleagues, and training workshops. This advice has worked well for me personally in the fields of marine ecology and conservation; as of this writing I have 14 published papers and have served as a peer reviewer for 26 different journals. However, there are lots of other strategies out there, and you should seek them out and figure out what works best for you, particularly if you’re in a radically different academic discipline.
Part 1: What is a scientific paper?
The process of writing and publishing peer-reviewed scientific papers can be confusing and intimidating to beginning students, who may know that these papers are professionally important but not how to create their own. Different in scope, style, and significance from a class term paper or thesis, these papers are formal, technical writeups of a scientific research project or idea. They are written by scientists or technical experts, and peer-reviewed by other scientists or technical experts who (ideally) provide constructive criticism.

BuzzFeed: the epitome of unnecessary hyperbole and an amalgam of often unoriginal content. I’ve long been convinced that this website is a waste of time and that it parrots bullshit in exchange for pageviews. Imagine my surprise, then, when I saw a recent article headlined, “17 Things Only Chronic Mosquito Victims Will Understand.”For a brief moment I was encouraged, hopeful even, that BuzzFeed might have turned a page and published something worth reading. You, wise reader, likely know this this turned out. Below I present 17 things which I think are actually worth knowing relevant to mosquitoes.

Earlier today, the New York Times reported that actor Leonard Nimoy had died at the age of 83. Coming just two days after the death of Genie Clark, this means that I’ve lost two of my childhood heroes in one week. I’ve already briefly written about what Genie meant to me and to my friends here and here and am quoted here, but Leonard Nimoy’s impact on me is a little harder to explain. I hope our readers will indulge me in an unusually personal post.
I’ve been a big fan of science fiction, something I’ve always loved sharing with my mother, since I was a kid. A world where science and intellect and technology, not brute force, are used to solve problems holds obvious appeal. To a kid who grew up struggling with some anti-Jewish discrimination, the diversity featured on shows like Star Trek was inspiring. People that were different didn’t have to hide their differences and lay low and try to avoid standing out in a crowd of people different from you, like I did. Not only did the main characters not tease and attack each other because they were different, but this behavior was actively portrayed as a problem on several episodes. The Federation wasn’t successful despite including different cultures and religions and even species, they were successful because of it. The environmental conservation message in Star Trek plotlines like “the Voyage Home” made a budding young conservation biologist relate to it even more.

You have probably heard that as the global climate changes due to human influence the sea surface is going to rise and the oceans will get warmer and more acidic. The bit about the oceans increasing in acidity is particularly troubling because it implies calcium carbonate based organisms (oysters, snails, corals, etc.) will simply dissolve in this future dystopian acid-ocean (that is a bit of an oversimplification, but you get the idea).
Ocean acidity is determined by measuring the pH, which relates acidity based on the number of hydrogen ions found in the water. So long story short, as more and more carbon dioxide (CO2) is emitted into the atmosphere, it in-turn fluxes into the oceans forming carbonic acid which results in the release of hydrogen ions lowering the pH. Simple logic would suggest that this spells bad news for calcifying organism (poor Mr. Snail).

Dr. Mickey von Dassow is a biologist who studies how biomechanics affects development-environment interactions. He received his PhD in Integrative Biology at UC Berkeley, studying how fluid flow affects colonial marine animals. As a postdoc (U. of Pittsburgh), he studied the mechanics of tissue movements that shape amphibian embryos. Currently he is a guest research scientist at the Duke Marine Lab, and works primarily on sea urchin embryos.

Can everyone do scientific research? I hope to convince you the answer is “yes.” I’m trying to develop an online platform (http://IGoR.wikidot.com) to help amateur scientists and other science enthusiasts do their own scientific research, while at the same time helping experienced scientists tap into the skills and creativity of a broader community. I hope you’ll love the idea and want to help me spark IGoR to life*.
Currently, the vast majority of scientific research is done by professionals supported by big institutions, such as universities, government labs, or corporations. It’s difficult for even a trained and experienced scientist to find the resources and time to do research without this backing. There are pockets of science where amateurs frequently make substantial contributions (e.g. amateur astronomy and taxonomy). However, it wasn’t that long ago that the majority of science was done by people – such as Darwin and Wallace – who were outside academia. In fact, the great intellectual revolutions that created modern science were not started by trained scientists: there were no trained scientists at the time!
