Why Are Only Some Cells ‘competent’ to Form Cancer?

Medical researchers report that melanoma formation depends on something called 'oncogenic competence,' which is the result of a collaboration between the DNA mutations in a cell and the particular ...

Mountaintop Mining Causes 40% Loss of Aquatic Biodiversity

Using environmental DNA scans of Appalachian streams, researchers found that the effects of mountaintop coal mining in West Virginia are even more widespread than previously reported: Streams from ...

Protruding Eyes, Mouth Make Stingrays More Hydrodynamically Efficient

Researchers detail how the protruding eyes and mouths on simulated stingrays affect a range of forces involved in propulsion, such as pressure and vorticity. They created a computer model of a ...

Hundreds of Cape Fur Seals Entangled in Fishing Lines and Nets Every Year

Fishing line and nets are having a major impact on Cape fur seals, the most common marine mammal observed around the coastline of South Africa and Namibia, where they are endemic. The first results ...

Cloud Shadows Cue Mini-Migrations

A new study shows that zooplankton swim up and down repeatedly within the ocean's twilight zone due to subtle changes in daylight intensity, with implications for deep-sea ecology and the ...

Developing Enhanced Fish Vaccines With Nanocellulose

Scientists are developing new fish vaccines using nanocellulose produced from Maine's wood pulp industry. Nanocellulose poses no known harmful effects to fish tissue and is unlikely to cause ...

Mystery of the Seadragon Solved

The genome of the seadragon, a very unusual fish, has been decoded. Seadragons (Phyllopetryx taeniolatus) live off the coast in western and southern Australia. Evolutionary biologists have now found ...

Protecting Largest, Most Prolific Fish May Boost Productivity of Fisheries

Management of many of the largest fisheries in the world assumes incorrectly that many small fish reproduce as well as fewer large ones with similar total masses, a new analysis has found. That can ...

The Arctic Ocean’s Deep Past Provides Clues to Its Imminent Future

As the Arctic Ocean warms and sea ice shrinks, will the newly exposed sea surface see a plankton population boom and a burgeoning ecosystem in the open Arctic Ocean? Not likely, say a team of ...

A new study has uncovered the engineering secrets behind what makes fish fins so strong yet flexible. The research could one day lead to new designs for robotic surgical tools or even airplane wings ...

‘Sticky Questions’ Raised by Study on Coral Reefs

A new study on the impact of climate change on coral reefs is raising sticky questions about conservation. It found coral in more polluted and high traffic water handled extreme heat events better ...

Shark Diversity Unaffected When the Dinosaurs Were Wiped Out, Study Finds

A global catastrophe 66 million years ago led to the extinction of all non-avian dinosaurs, and large marine reptiles like mosasaurs and plesiosaurs. But what happened to the sharks? According to a ...

What to Call Seafood Made from Fish Cells

Food companies, regulators, marketers, journalists and others should use the terms 'cell-based' or 'cell-cultured' when labeling and talking about seafood products made from the ...

Climate Change ‘double Whammy’ Could Kill Off Fish Species

New study of 150 million years of fish evolution provides first evidence to support scientific theory that commonly-eaten fish species will become smaller as waters warm under climate change. ...

The 'Phytoplankton Factory' -- From Nutrients to Algae Growth

Phytoplankton are the foundation of ocean ecosystems: like rainforests, they consume carbon from the atmosphere, form the basis of the marine food web and have a decisive influence on fish abundance ...

Overfishing and Other Human Pressures Are Severely Harming Many Marine Protected Areas Around the World, Study Finds

A new study points to a strong 'edge effect' in marine protected areas (MPAs), sharply reducing by 60 percent the fish population living up to 1 - 1.5 km within the MPA. This significantly ...

Plastic Creates 'Evolutionary Trap' for Young Sea Turtles

Plastic pollution creates an 'evolutionary trap' for young sea turtles, new research shows. After hatching on beaches, sea turtles travel on currents and spend their early years in the open ...

Buffer Zones, Better Regulation Needed to Prevent Agricultural Pollution in Rivers, Streams, Review Finds

Greater buffer zones around bodies of water and more consistent enforcement of water protection regulations are needed to reduce agriculture-based pollution in the Western U.S., a recent review has ...

eDNA Effective in the Calculation of Marine Biodiversity

For almost 20 years, researchers have conducted detailed censuses of the majestic kelp forests off Santa Barbara. By counting fish species and placing them in the context of their environmental ...

Cultural Biases Impact Native Fish, Too

From art to religion to land use, much of what is deemed valuable in the United States was shaped centuries ago by the white male perspective. Fish, it turns out, are no exception. A study explores ...

Targeted Removals and Enhanced Monitoring Can Help Manage Lionfish in the Mediterranean

New research represents one of the first studies to examine the effectiveness of targeted lionfish removals from both an ecological and a socio-economic ...

Who Eats the Invaders?
