Week in Review: Synthetic Coral Could Remove Toxic Metals, Octopus Genome Discoveries, and More!


1. Synthetic Coral Could Remove Toxic Heavy Metals


Image result for coral reefScientist from Anhui Jianzhu University in China published a study in the Journal of Colloid and Interface Science on a new material that could help remove pollutants from the ocean. The new material mimics coral and can help remove toxic metals like mercury, lead, and arsenic from the ocean. Removing these metals would not only be beneficial to the health of the ocean but also to humans. The World Health Organization reported that "between 1.5 and 17 in every thousand children living in selected subsistence fishing populations showed cognitive impacts caused by the consumption of fish containing mercury".

2. Octopus Genome Offers Insights Into Oddballs

  A recent report in the journal Nature reported one the complexity of the genetic code of the California two-spot octopus, scientific name is octopus bimaculoides. Scientists studied the species to understand how they are able to regrow lost arms, change the color of their skin, and travel through the ocean using jet propulsion. Surprisingly, the octopus genome was made us of 150-160 genes which is more than what was expected in invertebrates. The arm's suckers were a particular point of interest and reviews the gene activity that is similar to signaling between neurons in other animals. Read more...

3. Meet the Echo Seeker

Every week we discuss some of the deep water discoveries of  unmanned vehicles (UAV) but, do you really know what this technology looks like? Boeing has recently released information on their Echo Seeker submersible. Because of the extreme pressure, the design and function of this vehicle is significantly different from the defense contractor's  space vehicles. The UAV can submerge to depths of 20,000 feet and can perform 3 day long missions. Read more...

4. India Could Lead on Climate Change




“India can show that you can be better off with basic needs fulfilled and a sustainable lifestyle,” says the Ambassador. Picture shows a solar thermal power plant in Aburoad, Rajasthan.
As the world prepares for the UN Framework Convention on Climate Change (UNFCCC) in Paris at the end of this year, nations have prepared their proposals to change the energy policies. India is one nation that has already started the transformation. The country has embraced more sustainable lifestyle models, development into renewable energy, and increased access to energy and cleaner development.  Read more...

5. Is This The Biggest Great White Shark Ever Filmed?

This week, off of the coast of Mexico's Baja California, Guadalupe Island, biologist Mauricio Hoyos Padilla filmed a 20 foot great white shark. The average length of a great white shark is any where between 12 to 14 feet long. Padilla also believes the shark was pregnant which is always a positive considering the extremely low population numbers. To see the video recorded click here...

6. Watch This Leaping Great White Shark Get Some Serious Air

We have to admit, our mathematical minded members of Sea Save nerded out a bit when we came across this article. This insane video shows a shark launch itself out of the water like a missile coming out of a submarine. Wired did some of the math and determined that the shark, approximately 7.5 feet, launched itself at a velocity of 17.5 mph! That's extremely fast. See the video here...

7. Humans Used Up a Year Worth of Natural Resources in Under 9 Months

According to the Global Footprint Network, humans had consumed an entire year's worth of natural resources already this year. Resources reviewed include space, food, fiber, timber, and many more. Based on the current consumption rate, humans would require 1.6 planet earths to support this lifestyle.  Read more...
