The first complete genus-level dated phylogeny of palms reveals insights into the evolution of rainforests.
The U.S. Environmental Protection Agency (EPA) and other federal agencies are teaming up to document and track potential marine debris generated by the Japan earthquake and tsunami in March.
Slow-moving winter weather systems that can lead to massive snowfalls are more frequent during the decades when the North Atlantic Ocean is warmer than usual, a new NASA study finds. The study demonstrates that the impacts of such systems, which are often fueled by an atmospheric phenomenon known as atmospheric blocking, go far beyond the atmosphere and can trigger changes in ocean circulation.
Scientists braved ticks and a tiger to discover how human activities have perturbed the nitrogen cycle in tropical forests. Studies at two remote Smithsonian Institution Global Earth Observatory sites in Panama and Thailand show the first evidence of long-term effects of nitrogen pollution in tropical trees.
Both climate change and humans were responsible for the extinction of some large mammals, according to research that is the first of its kind to use genetic, archeological, and climatic data together to infer the population history of large Ice-Age mammals.
There’s an unsuspecting culprit contributing to U.S. water pollution: pet poop.

Plants do not have eyes or legs, yet they are able to "see" and move toward and away from light. This ability, called phototropism, is controlled by a series of molecular-level signals between proteins inside and between plant cells. In a paper published in The Plant Cell, University of Missouri scientists report for the first time the elusive role a critical protein plays in this molecular signaling pathway that regulates phototropism in plants.
As the leaves change and temps drop, the crisp autumn air brings a whole new load of waste possibilities with the new season. As opposed to the scorching summer months coupled with UV rays that dry lawns and surge kilowatts of electricity through homes for cooling, fall brings gutter clutter and leaf waste – not to mention high kilowatt usage in parts of the world prone to freezing temps.
The U.S. Environmental Protection Agency (EPA) recently announced funding for Great Lakes Restoration Initiative projects in Northern Michigan totaling $1.1 million.
Research suggests soil environment determines humus depletion, which means the question as to how soils respond to global climate change needs to be readdressed.
Changing human activities coupled with a dynamic environment over the past few centuries have caused fluctuating periods of decline and recovery of corals reefs in the Hawaiian Islands, according to a study sponsored in part by the Institute for Ocean Conservation Science at Stony Brook University.
In a new study, UC Santa Barbara scientists explain how they used DNA to identify microbes present in the Gulf of Mexico following the Deepwater Horizon oil spill, and how they identified the microbes responsible for consuming the large amount of natural gas present immediately after the spill.
As the nation heightens security measures across land, air and sea; any proposed tactic in the effort to ward off hostiles is being employed – including an elite team of 75 bottlenose dolphins and 35 California sea lions trained to defend the nation.

Researchers led by MIT professor Daniel Nocera have produced something they’re calling an “artificial leaf”: Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as an energy source.
A team of Russian veterinary colleagues and health experts from the Wildlife Conservation Society's Bronx Zoo are collaborating to understand how distemper -- a virus afflicting domestic dogs and many wildlife species -- may be a growing threat to Siberian (Amur) tigers.
When a species recovers enough to be removed from the federal endangered species list, the public trust doctrine – the principle that government must conserve natural resources for the public good – should guide state management of wildlife, scientists say.
Coral reefs that have lots of corals and appear healthy may, in fact, be heading toward collapse, according to a study published by the Wildlife Conservation Society and other groups.
The invasive sea squirt, Styela clava, has now been discovered along the Eastern Seaboard as far south as Bridgeport Harbor and poses a significant danger to Connecticut’s $30 million shellfish business, according to field research conducted by Carmela Cuomo, head of the marine biology program at the University of New Haven, and several of her students.
A research team led by LSU professors Fernando Galvez and Andrew Whitehead has published the results of a combined field and laboratory study showing the effects of the Deepwater Horizon oil spill on fish living in Louisiana marshes.
A sorghum hybrid that does not flower and accumulates as much as three times the amount of stem and leaf matter may help the bioenergy industry, according to a study appearing in the Proceedings of the National Academy of Sciences.
