Humans are edging closer and closer to telepathic communication where one human communicates with another purely from thinking. Wait… what’s that you say? We are already there?! Like something out of a sci-fi thriller neuroscientists in Europe and America demonstrated the viability of direct brain-to-brain communications in humans.
“Brain-to-brain (B2B) communication system overview.
On the left, the BCI subsystem is shown schematically, including electrodes over the motor cortex and the EEG amplifier/transmitter wireless box in the cap. Motor imagery of the feet codes the bit value 0, of the hands codes bit value 1. On the right, the CBI system is illustrated, highlighting the role of coil orientation for encoding the two bit values. Communication between the BCI and CBI components is mediated by the internet.” (Photo credit: Grau et al. 2014)

“To build a city at the bottom of the sea! Insanity. But where else could we be free from the clutching hand of the Parasites? Where else could we build an economy that they would not try to control, a society that they would not try to destroy? It was not impossible to build Rapture at the bottom of the sea. It was impossible to build it anywhere else.”
Andrew Ryan, Bioshock
Rapture, a city beneath the sea, the crowning achievement of Randian industrialist Andrew Ryan. This atmospheric world of technological wonder and urban decay serves as the setting for one of the greatest video games of all time, Bioshock. The player, finding themselves stranded at sea in a fiery plane crash, makes their way towards a lonely lighthouse, descends into the sunken, desolate city, and unlocks the mysteries surrounding the creation and destruction of a most unusual city.
Rapture. From Bioshock.
Though many questions are answered as the player journeys into the heart of Rapture, collecting audio diaries of its residents along the way, one question still eludes: How deep is Rapture and where, exactly, is it?

In a very basic sense there is a general dichotomy in the grouping of organisms on this planet as either a plant or as an animal. Myself, like most of the rest of you, belong to the animal group, but there are those organisms out there that exists on the boundary; one in particular is the sea slug, Elysia chlorotica.

It’s around about this time of year when people begin to question their New Year’s resolutions to commit to better health. You know what I am talking about. Right after NYE the number of people at the gym swells to an unholy number of hopeful fitness do-gooders. Yet without fail, by the end of the month the gym population begins to stabilize back to its pre New Year’s resolution numbers. But maybe, just maybe, this article will convince you to stick with your commitment to better health, change your DNA regarding your approach to fitness, and keep on exercising! Because exercise, as a new study has found, does just that. Exercise changes the shape and functioning of our genes, an important step on the way to improved health and fitness!

Finally, President Obama’s state of the union called out Congress’s problem with climate change. Their denial is merely a symptom of overall scientific ignorance, a simply medieval issue that has temporarily stalled many great nations’ progress throughout history. Yet, President Obama’s points about climate change and it’s relevance to the nation gives one hope that there is a small smoldering ember of collaborative-driven leadership buried under piles of Benghazi reports, and it couldn’t come a moment too soon. The USA has stalled its scientific and technological growth at a key time in global history and is already generations behind the modern world in technological advancements to protect its people against a rising threat – the ocean.
Let me present you with a case study. I live in Zeeland in the Netherlands, and this area is protected by the world-famous Oosterschelde surge barrier; a 9km system of dams, movable concrete slabs, and artificial islands. The Oosterschelde is one of many ocean barriers strategically placed along the Dutch coast and has been deemed one of the Seven Wonders of the Modern World by the American Society of Civil Engineers. During storm events, the Oosterschelde’s massive concrete slabs shut and cut off Zeeland’s waterways from the surge of the North Sea.

Last month, a team of marine scientists (which included Andrew and I) published a paper pointing out that intentionally killing the largest and most fecund members of IUCN Red List Threatened species is not a good thing and could be easily stopped (by stopping record awards entirely for these species or moving to a catch and release model)
Our recommendations were not universally supported by scientists, and we received criticism from respected colleagues largely in the form of “this isn’t a particularly big problem, no serious people care about it.” There was also an official response from the IGFA to this effect, which we issued an official response to. Sure. It isn’t the biggest problem in the world, but it is a problem. And you’d be hard-pressed to find a conservation problem that’s easier to solve.
A petition created by the Blue Planet Society based on our recommendations has, as of this writing, surpassed 6,000 signatures from all over the world, including many from scientists, fisherman and professional conservation activists. The paper has also been widely discussed on social media
Presented here are some quotes from scientists, fishermen and conservationists supporting our recommendations. While this support does not inherently mean that the issues we raise are important, it certainly shows that lots of serious people care about it.

Dr. Andrew Wright is a British marine biologist that has been working on the science-policy boundary around the world for over a decade. His experiences have led him to champion a better communication of science to policy makers and the lay public. His research has included a population viability analysis for the vaquita, sperm whales bioacoustics and the impacts of noise on various marine mammals. Andrew is currently working on several projects, most relating to investigating either sleeping behaviour or chronic stress in wild cetaceans. He is also spearheading efforts to bring more marketing techniques into conservation outreach.
Dr. Naomi Rose is the marine mammal scientist for the Animal Welfare Institute (AWI). She handles AWI campaigns to protect wild and captive marine mammals and is a member of the International Whaling Commission’s Scientific Committee. She has published popular and scientific articles, authored book chapters, and lectures annually at several universities. She participates in workshops and task forces at the international, national and state level.

What you are looking at is not a prop from a science fiction movie, but a very earthly (or more accurately marine) wildlife organ that is causing Mexico quite a bit of trouble. It’s the swim bladder of the totoaba fish. Unrelated to bladders with which people are more familiar, it is a collagen-rich organ that the fish fills with air in order to remain buoyant in the water column and save energy when swimming. It is, quite literally, a bag of hot air. This one is dried and ready for shipping – it is prized as a delicacy in China, where it is believed to rejuvenate skin and (of course) act as an aphrodisiac. (more…)
