El Niño played a key role in Pacific marine heatwave, as did potentially climate change
The Northeast Pacific's largest marine heatwave on record was at least in part caused by El Niño climate patterns. And unusually warm water events in that ocean could potentially become more frequent with rising levels of greenhouse gases. (2016-07-12)

Metal-ion breakthrough leads to new biomaterials
Metals such as iron and calcium play a crucial role inside the human body, so it's no surprise that bioengineers would like to integrate them into the soft, stretchy materials used to repair skin, blood vessels, lungs and other tissue. (2020-09-30)

Marine sediment microbial fuel cells get a nutritional boost
Discarded crab and lobster shells may be the key to prolonging the life of microbial fuel cells that power sensors beneath the sea, according to a team of Penn State researchers. (2007-06-04)

Depression-era drainage ditches emerge as sleeping threat to Cape Cod salt marshes
Cape Cod, Massachusetts has a problem. The iconic salt marshes of the famous summer retreat are melting away at the edges, dying back from the most popular recreational areas. The erosion is a consequence of an unexpected synergy between recreational over-fishing and Great Depression-era ditches constructed by Works Progress Administration in an effort to control mosquitoes.

Extinct sea scorpion gets a Yale eye exam, with surprising results
Poor peepers are a problem, even if you are a big, bad sea scorpion. One minute, you're an imperious predator, scouring the shallow waters for any prey in sight. The next, thanks to a post-extinction eye exam by Yale University scientists, you're reduced to trolling for weaker, soft-bodied animals you stumble upon at night. (2014-07-10)

From guts to glory: The evolution of gut defense
Gut 'missing link' shows how mammals evolved to live with their microbes. (2018-08-24)

Injectable 'smart sponge' holds promise for controlled drug delivery
Researchers have developed a drug delivery technique for diabetes treatment in which a sponge-like material surrounds an insulin core. The sponge expands and contracts in response to blood sugar levels to release insulin as needed. The technique could also be used for targeted drug delivery to cancer cells. (2013-07-17)

Queen conch shell suggests new structure for ceramics
CWRU researchers report in the June 29 (2000-07-10)

Sunlight, PCB exposure enhance skin cancer chances
Sunlight and PCB exposure can hit you where you least expect it. The combination enhances the development of non-melanoma skin cancer on parts of the body not directly exposed to the sun, according to a University of Illinois study. (2002-03-21)

To push or to pull? How many-limbed marine organisms swim
Couinter-intuitively, small marine animals don't use their limbs or propulsors to push themselves through the water while swimming. Instead, their appendages create negative pressure behind them that pulls the animal through the water, scientists from the Marine Biological Laboratory report. (2020-11-24)

Where the wild things go... when there's nowhere else
The presence of endangered cats and primates in swamp forests might be seriously overlooked. Princeton research concludes that swamp forests beg further exploration as places where endangered species have preserved their numbers -- and where humans could potentially preserve them into the future. (2013-02-28)

Biomimetic micro/nanoscale fiber reinforced composites
For the first time, through a programmed and consecutive 'brushing-and-laminating' assembly strategy, macroscopic 3-D bulk biomimetic twisted plywood structural materials with comprehensive mimicry of structural and mechanical characteristics of their natural counterparts are successfully fabricated from 1D micro/nanoscale building blocks under mild conditions. As expected, they achieve excellent mechanical properties superior to many natural, artificial and engineering materials. More importantly, the proposed assembly strategy is high-efficient, scalable and material-independent. (2018-08-10)

New study takes the shine off magpie folklore
Magpies are not attracted to shiny objects and don't routinely steal small trinkets such as jewelry, according to a new study. (2014-08-15)

MCA applauds council action to protect Northern Bering Sea habitat
Action to close over 130,000 square miles of the Northern Bering Sea to bottom trawling is an important step for the health of Alaska's oceans ecosystem and the seafood industry, MCA executive director David Benton said today. The North Pacific Fishery Management Council took the action during a meeting today in Sitka to protect waters that are important for fish stocks, crab, and other species like gray whales, walrus and eiders.

Predator or not? Invasive snails hide even when they don't know
The specific cues that trigger an animal's natural defense vary depending on the species and its history in the ecosystem, a new University of Washington study finds. (2017-01-24)

Seafood mislabeling is having negative impacts on the marine environment
As the most globally traded food commodity, seafood production and its supply chains are often complex and opaque. Contemporaneous with the increase in seafood consumption, evidence of mislabeling has become ubiquitous. Yet, little is known about the consequences of seafood mislabeling. New research by Advanced Conservation Strategies and colleagues show that conditions exist for mislabeling to generate negative impacts on marine populations and to support consumption of products from poorly managed fisheries.

New fossils demonstrate that powerful eyes evolved in a twinkling
Palaeontologists have uncovered half-a-billion-year-old fossils demonstrating that primitive animals had excellent vision. An international team led by scientists from the South Australian Museum and the University of Adelaide found the exquisite fossils, which look like squashed eyes from a recently swatted fly. (2011-06-29)

Animals keep viruses in the sea in balance
A variety of sea animals can take up virus particles while filtering seawater for oxygen and food. Sponges are particularly efficient. That was written by marine ecologist Jennifer Welsh from NIOZ this week, in a publication in Nature Scientific Reports. This Monday, Welsh will defend her thesis at the Free University of Amsterdam, through an online connection. (2020-03-27)

Gulf of Maine marine ecosystem may have entered new phase
For most of the past 4,500 years, cod was king in the Gulf of Maine's coastal waters. Today, cod have given way to the Jonah crab with potential long-term consequences for coastal fisheries, according to a University of Maine research report published in the journal Ecosystems. (2004-08-03)
