Happy FSF! As some of you may know (and for those who don’t), I study the bottom of the ocean, and I do so primarily using innovative technology to image the seafloor (e.g., Wormcam). The interesting work I’ve conducted has resulted in me having the opportunity to present my work to a larger lay audience, in the form of a TEDx presentation.

I am giving my TED talk with my good buddy and colleague Steve Sabo. In our talk, “A Picture is Worth a Thousand Worms”, Steve & I will illustrate the significance of the ocean floor through advancements in underwater camera technology and data visualization, making complex science more accessible for everyone.

Pollination. I think most people understand why this is important (or maybe I should say, I hope). To put it simply, the process of pollination facilitates reproduction in plants by transferring pollen from one plant to another. In the terrestrial world, this can be mediated by physical forcing (e.g., wind) or by animals (e.g., insects) – and its why people are freaking out about the loss of bees due to pesticides (because they are a primary pollinator), but I digress. Until relatively recently, pollination by animals was not thought to occur in the ocean. Unlike on land, where most flowering plants rely on creatures to carry pollen, plant reproduction in an aquatic world was surmised to rely exclusively on currents and tides. However, a team of researchers led by marine biologist Brigitta van Tussenbroek revoked the long standing paradigm that pollen in the sea is transported only by water, discovering and documenting the process of zoobenthophilous pollination (a term they coined).

In today’s FSF we bring you both a jaw dropping, and somewhat terrifying cinematic visualization of how bacteria evolve resistance to antibiotics, and overtime can become super bugs immune to any antibiotic treatment. A concise and detailed description is presented below:
This stunning video of evolution in action captures how bacteria with no resistance to an antibiotic can in a very short time become resistant to concentrations of more than a thousand times the initial concentration. Other scientists have documented this phenomenon before, but never with such vivid clarity as that provided by Michael Bay and Roy Kishony of Harvard University.
A great white shark nursery in the North Atlantic that was discovered in 1985 south of Cape Cod in the waters off Montauk, New York has received renewed attention due to the increased activity of white sharks off cape cod in recent years. The nursery was first documented in 1985 by Casey and Pratt who deduced the presence of a nursery based on the number of juvenile sightings and landings in the area. This work was followed up recently by OCEARCH (an organization dedicated to generating scientific data related to tracking/telemetry and biological studies of keystone marine species such as great white sharks), which tagged and tracked nine infant great whites to the nursery, located a few miles off Montauk.

The oceans belong to all of us. With this simple statement in mind, the Oceanography for Everyone (OfE) project was launched with the goal of making ocean science more accessible. One of the biggest hurdles in conducting ocean science is instrumentation costs, and 4 years ago the OfE team began trying to make one of the most basic ocean science tools, the CTD (a water quality sensor that measures Conductivity-Temperature-Depth), cheaper… much, much cheaper!
Recently a team of scientists on a deep sea expedition in the Northwestern Hawaiian Islands aboard the R/V Okeanos Explorer made a monumental discovery… pun intended. While exploring the depths of the seafloor in Papahānaumokuākea Marine National Monument, with their remotely operated vehicles (ROV) Seirios and Deep Discover, they discovered and documented the largest sponge ever observed on this planet… or any planet for that matter.

Do you ever get that feeling that you are being watched? I imagine that is what the ospreys at the nesting platform at the Virginia Institute of Marine Science (VIMS) must feel, if they notice at all. These birds have a camera that is trained on their nest 24/7 during the osprey breeding season (generally from mid-March to October).

Ospreys are unique among North American raptors for their diet of live fish and ability to dive into the water to catch them. As a result of their life history strategies, osprey nests occur around nearly any body of water: saltmarshes, rivers, ponds, reservoirs, estuaries, and even coral reefs. The placement of OspreyCam at VIMS provides us with an around-the-clock window into the world and “family” dynamics of these amazing birds. We are able to watch as a mating pair cohabit their nest and use it to rear their young. As you can imagine, once the chickies hatch, things get quite interesting in the osprey nest!

The interwebs have been going crazy the past few days with the recent announcement that scientists have for the first time detected gravitational waves, the ripples in the fabric of space-time that Einstein predicted a century ago. In terms of scientific advancement, to quote Joe Biden, “This is a big fucking deal!” Bigger than the discovery of the subatomic Higgs boson particle (i.e., the god particle), and it has been suggested this discovery is comparable only to “Galileo taking up the telescope and looking at the planets.” – Penn State physics theorist Abhay Ashtekar

Every year modern medicine brings more and more surprises. It really does seem that the limitations of man’s achievements are solely limited to our creative ability to dream what is possible. This week we bring you the bionic eye. As part of an ongoing trial at Oxford’s John Radcliffe Hospital surgeons implanted a micro electric chip into a patients eye restoring part of her sight.
In response to unprofessional behavior by another scientist, a marine science colleague recently stated that they were so used to bad behavior in their area of research that they just accepted it as normal, and that they basically had “Stockholm syndrome”. Sadly this all too common, that unprofessional behavior in some fields and areas is so common (whether it be academic bullying and hazing, plagiarizing and stealing ideas and data, or sexism and harassment see The Dark Side of Academia) that it becomes the accepted norm. This is particularly prevalent in fields that are small and insular.
Stockholm, despite its associated syndrome, is really quite lovely
