Containing Asia’s coasts is out best bet for plastic-free ocean

Plastic bags, bottle caps and plastic fibres are among the myriad of micro plastic debris that wash out into the Pacific Ocean. These get ingested by the marine life like fish, mammals and birds which are dying from choking, intestinal blockage and starvation. Moreover, some are toxic pollutants that are absorbed, transported, and consumed in the food chain eventually reaching humans. The most effective way to contain microplastics is to raise floating nets around Asia’s coats, not around the Great Pacific Garbage patch, researchers reckon.

High-resolution spectroscopy could revolutionize seawater uranium capture

New imaging techniques might revolutionize the technologies currently used to capture uranium from seawater, as researchers gain a better understanding of the way the compounds that bind the atoms interact with them.

How some fish use polarized light to make themselves invisible to predators

You’d think there’s not much a little fish can do to hide from predators in open waters. But when rocks, algae and other marine nooks and crannies are nowhere to be found, fish turn to manipulate the physical interactions of light to balance the scale. For instance, some open ocean fish species employ specialized skin cells that reflect polarized light. This reflection is most effective, not coincidentally, at the ‘chase angle’ or from the predator’s point of view. It’s so effective that the US Navy is funding work that might shed light how exactly some fish do this and how this can be applied to make submersibles equally inconspicuous.
