A new study shows that the number of "dead zones" -- areas of seafloor with too little oxygen for most marine life -- has increased by a third between 1995 and 2007. Dead zones are now "the key stressor on marine ecosystems" and "rank with over-fishing, habitat loss, and harmful algal blooms as global environmental problems." View the full article

The search for what causes a debilitating shell disease affecting lobsters from Long Island Sound to Maine has led one Marine Biological Laboratory visiting scientist to suspect environmental alkyphenols, formed primarily by the breakdown of hard transparent plastics. View the full article

Human activities are cumulatively driving the health of the world's oceans down a rapid spiral, and only prompt and wholesale changes will slow or perhaps ultimately reverse the catastrophic problems they are facing. View the full article

Devastating declines of amphibian species around the world are a sign of a biodiversity disaster larger than just frogs, salamanders and their ilk, according to researchers from the University of California, Berkeley. (2008-08-13) View the full article

Researchers have harnessed the sensitivity of days-old fish embryos to create a tool capable of detecting a range of harmful chemicals. By measuring rates of oxygen use in developing fish, which are sensitive to contaminants and stressful conditions, the technology could reveal the presence of minute levels of toxic substances before they cause more obvious and substantial harm. It could be used as an early warning system against environmental contamination or even biological weapons. View the full article

In the waters surrounding Woods Hole, Massachusetts, the warty comb jelly, Mnemiopsis ledyi, lives out its days, bumping against eel grass and collecting small crustaceans with its sticky tentacles. The delicate creature, which resembles a small jellyfish without the stinger, is just another member of the food web here on the Western Atlantic coast. View the full article

Massachusetts fisherman once considered the New England whelk or ?conch? as nothing more than bycatch. Although demand existed for the large-shelled snail, traditionally used for cooking in East Asian cultures, it could more easily be trawled in the waters around South America, the Caribbean and Asia, making conch unprofitable in the Northeast. This turned around in the 1980s, however, when overfishing of whelk quickly transformed the small New England conch fishery into a multi-million dollar industry. View the full article

Elephant seals are helping scientists overcome a critical blind-spot in their ability to detect change in Southern Ocean circulation and sea ice production and its influence on global climate. View the full article

Long a problem in the western US, the New Zealand mud snail currently inhabits four of the five Great Lakes and is spreading into rivers and tributaries, according to researchers. These tiny creatures out-compete native snails and insects, but are not good fish food replacements for the native species. View the full article

Marine biologists have just completed a pioneering research effort in Hawaii to measure the biology and behavior of some of the most poorly understood whales on Earth. During the study, for the first time, scientists attached listening and movement sensors on marine mammals around realistic military operations. View the full article

Researchers have discovered a marine compound off the coast of Key Largo that inhibits cancer cell growth in laboratory tests. Largazole, named for its Florida location and structural features, seeks out a family of enzymes called histone deacetylase. Overactivity of certain HDACs has been associated with several cancers such as prostate and colon tumors, and inhibiting HDACs may activate tumor-suppressor genes that have been silenced in these cancers.
