A recent paper in the Journal of Physical Oceanography details the specific challenges posed by the many millions of tons of plastic dumped into the ocean every years. The findings indicate that solving the problem may have complicating factors beyond just raw scale (4.8 million to 12.7 million metric tons of dumped in 2015 alone). Read about the research on EurekAlert!.

Video: New Princeton University research proves that ocean currents can move particles like phytoplankton and plastic debris all the way across the world in significantly less time than previously thought. Find out how in this video and on EurekAlert!.

ASU researcher says now is the time to prioritize endangered species
Currently, resources allocated to recover endangered species are insufficient to save all listed species, and with a scarcity of funds what is needed to be effective is a more analytical approach that can bring clarity and openness to resource allocation, argues Leah Gerber, an Arizona State University conservation biologist.

Fish and insects guide design for future contact lenses
Making the most of the low light in the muddy rivers where it swims, the elephant nose fish survives by being able to spot predators amongst the muck with a uniquely shaped retina, the part of the eye that captures light. In a new study, researchers looked to the fish's retinal structure to inform the design of a contact lens that can adjust its focus.

Carbon from land played a role during last deglaciation
As the Earth emerged from its last ice age several thousand years ago, atmospheric carbon dioxide increased and further warmed the planet. Scientists have long speculated that the primary source of this CO2 was from the deep ocean around Antarctica, though it has been difficult to prove. A study published this week confirmed that theory.

How the brain detects short sounds
For humans to understand speech and for other animals to know each other's calls, the brain must distinguish short sounds from longer sounds. By studying frogs, University of Utah researchers figured out how certain brain cells compute the length of sounds and detect short ones.

Desert cactus purifies contaminated water for aquaculture, drinking and more (video)
Farm-grown fish are an important source of food with significant and worldwide societal and economic benefits, but the fish that come from these recirculating systems can have unpleasant tastes and odors. To clean contaminated water for farmed fish, drinking and other uses, scientists are now turning to an unlikely source -- the mucilage or inner 'guts' of cacti. Researchers will be presenting their latest findings at the 251st National Meeting of the American Chemical Society.

Lake Huron's Chinook salmon fishery unlikely to recover due to ongoing food shortage
Lake Huron's Chinook salmon fishery will likely never return to its glory days because the lake can no longer support the predatory fish's main food source, the herring-like alewife, according to a new University of Michigan-led computer-modeling study.

Satellites and shipwrecks: Landsat satellite spots foundered ships in coastal waters
Using data from the NASA/USGS Landsat 8 satellite, researchers have detected plumes extending as far as 4 kilometers (about 2.5 miles) downstream from shallow shipwreck sites.

Evidence in the Cassia Hills of Idaho reveals 12 catastrophic eruptions
Ancient super-eruptions west of Yellowstone, USA, were investigated by an international initiative to examine the frequency of massive volcanic events. Yellowstone famously erupted cataclysmically in recent times, but these were just the latest of a longer succession of huge explosive eruptions that burned a track from Oregon eastward toward Yellowstone during the past 16 million years.

Conservation sea change
Beyond the breakers, the ocean is like the Wild West. While not completely lawless, its vastness and remoteness make it hard to observe and more difficult to manage human activity.

Small brain is good for the immune system -- if you are a fish
Having a small brain may provide immune benefits, at least if you are a guppy. A new study published in the journal Proceedings of the Royal Society shows that guppies with smaller brains have stronger immune responses than guppies with larger brains.
