500 million years of errors: Brachiopod shells record shadow of arms race in ancient oceans
A study of fossils from the Paleozoic Era, collected across the world, reveals that ancient brachiopods were little bothered by predators. However, the rare predation traces left on brachiopod shells by unknown assailants coupled with a subtle increase in their frequency through time may be the shadows on the wall that show killers were in the... view more...

Deep in the ocean, a clam that acts like a plant
How does life survive in the black depths of the ocean? At the surface, sunlight allows green plants to "fix" carbon from the air to build their bodies. view more (2007-02-21)
Scientists: New phylum sheds light on ancestor of animals, humans
Genetic analysis of an obscure, worm-like creature retrieved from the depths of the North Atlantic has led to the discovery of a new phylum, a rare event in an era when most organisms have already been grouped into major evolutionary categories. view more (2006-11-03)
Ocean temperature predicts spread of marine species
Scientists can predict how the distance marine larvae travel varies with ocean temperature - a key component in conservation and management of fish, shellfish and other marine species - according to a new study from the University of North Carolina at Chapel Hill. view more (2006-12-26)
Sea Grant warns of dumping seafood
In its latest outreach campaign, MIT Sea Grant has developed an educational pamphlet to encourage people not to release or dump live and fresh seafood and seafood waste into the wild. view more (2006-06-22)
Overfishing great sharks wiped out North Carolina bay scallop fishery
Fewer big sharks in the oceans led to the destruction of North Carolina's bay scallop fishery and inhibits the recovery of depressed scallop, oyster and clam populations along the U.S. Atlantic Coast, according to an article in the March 30 issue of the journal Science. view more (2007-03-30)
Exxon Valdez oil found in tidal feeding grounds of ducks, sea otters
Seventeen years after the Exxon Valdez ran aground in Alaska's Prince William Sound, compelling new evidence suggests that remnants of the worst oil spill in U.S. history extend farther into tidal waters than previously thought, increasing the probability that the oil is causing unanticipated long-term harm to wildlife. view more (2006-05-16)
MBL Scientists Find Evidence of RNA in Organelle Essential to Cell Division
Despite more than a century of study, scientists know relatively little about the inner workings of centrosomes—organelles essential to cell division in humans and animals. view more (2006-06-07)
Asphalt flows from deep-sea volcanoes
New kind of volcano discovered in the Gulf of Mexico Underwater volcanoes that spew asphalt instead of lava: they were discovered in the Gulf of Mexico during an expedition of the research vessel SONNE, led by Prof. Gerhard Bohrmann of the DFG Research Center Ocean Margins. On these volcanoes the multinational team of scientists encountered a... view more... (2004-05-17)
Overfishing large sharks impacts entire marine ecosystem, shrinks shellfish supply
Fewer big sharks in the oceans mean that bay scallops and other shellfish may be harder to find at the market, according to an article in the March 30 issue of the journal Science, tying two unlikely links in the food web to the same fate. view more (2007-03-30)
Paleontologists learn how not to become a fossil
The best way to avoid becoming a fossil is to be small and live in deep, tropical waters. So say four paleontologists who have published a detailed, global study of clam preservation. view more (2006-04-13)
Ocean floor geysers warm flowing sea water
An international team of earth scientists report movement of warmed sea water through the flat, Pacific Ocean floor off Costa Rica. The movement is greater than that off midocean volcanic ridges. The finding suggests possible marine life in a part of the ocean once considered barren. view more (2008-09-23)
Major international study warns global warming is destroying coral reefs and calls for 'drastic actions'
If world leaders do not immediately engage in a race against time to save the Earth's coral reefs, these vital ecosystems will not survive the global warming and acidification predicted for later this century. That is the conclusion of a group of marine scientists from around the world in a major new study published in the journal Science on Dec.... view more... (2007-12-26)
Ancient whale fall from California's Año Nuevo Island one of youngest, most complete known
A fossilized whale skeleton excavated 20 years ago amid the stench and noise of a seabird and elephant seal rookery on California's Año Nuevo Island turns out to be the youngest example on the Pacific coast of a fossil whale fall and the first in California, according to University of California, Berkeley, paleontologists.

Are walruses right-handed?
Walruses are 'right-flippered', according to research published this week in BMC Ecology. The first study of walrus feeding behaviour in the wild showed that the animals preferentially use their right flipper to remove sediment from buried food. This is the first time that any aquatic animal has been shown to prefer using one flipper to the other... view more... (2003-10-17)
Risk factors in contracting cancer of the endometrium
The risk of having endometrial cancer increases with obesity, thyroid alterations, hypercholesterolemia and mellitus diabetes. The probabilities of contracting this disease are also increased in those women who have a family history of this type of cancer and also with the consumption of animal fat, visceras and smoked fish. This is what Pamplona... view more... (2005-05-25)
Study reveals predation-evolution link
The fossil record seems to indicate that the diversity of marine creatures increased and decreased over hundreds of millions of years in step with predator-prey encounters, Virginia Tech geoscientists report in the Proceedings of the National Academy of Science. view more (2007-09-11)
Edible bivalves as a source of human pathogens: signals between vibrios and the bivalve host.
Clams, mussels and oysters are important vehicles for the transmission of enteric diseases when consumed raw or undercooked. Vibrio species, including human pathogens, are particularly abundant in bivalve tissues, where they can persist even after cleaning procedures, thus representing a potential risk for human health. Although different... view more... (2005-05-25)
New map outlines risk of zebra mussel invasion
The spread of two invasive alien freshwater mussel species - the zebra mussel and the quagga mussel - appears to be controlled in part by calcium levels in streams and lakes and a new risk assessment based on water chemistry suggests the Great Plains and American Southwest could be next in line for invasion. view more (2007-12-04)
Rare albino ratfish has eerie, silvery sheen
A ghostly, mutant ratfish caught off Whidbey Island in Washington state is the only completely albino fish ever seen by both the curator of the University of Washington's 7.2 million-specimen fish collection and a fish and wildlife biologist with more than 20 years of sampling fish in Puget Sound. view more (2007-09-25)
