Tiny critters: Though all smaller than a millimeter in size, four critters highlighted by Neatorama are much larger in effectiveness. When there is no oxygen around to speak of (or to breathe in), shewanella inhales the likes of uranium and chromium. The bacterium exhales the toxic metals with a few…

The recent expansion of hydraulic fracturing across the nation has set off a debate among oil and gas industry officials and conservationists and environmental scientists. During a recent House Space, Science and Technology Committee hearing, Congressman John Sarbanes (D-MD) outlined the points of contention: “You have one group that’s got long experience with hydraulic fracturing [contending] it’s very safe” and…

International interest and investment in nanotechnology is growing—said panelists in this morning’s public forum in Washington, D.C. hosted by RTI International—and development and commercialization of this technology need to meet societal expectations. That is, explained moderator Jim Trainham of RTI, the public is concerned with understanding and controlling nanotechnology since, if it cannot be controlled, the technology is not considered…

Scientists have found what appears to be the stress signals of a lake ecosystem that is on its way to collapse. Stephen Carpenter of the University of Wisconsin, Madison and colleagues carefully monitored the food web in a Wisconsin lake as they gradually introduced largemouth bass into the ecosystem. The researchers noticed a shift in the algae populations that were…

This post contributed by Terence Houston, ESA Science Policy Analyst Is your neighborhood capable of weathering a flood? Would you still be able to drink tap water after such an event? Are the levees, dams, bridges and storm drains in your town capable of coping with a potential flood? The United States Geological Survey (USGS)–at least for the time being–…

Pollution is not limited to toxic chemicals in the air and water—light pollution in urban environments, for example, has been shown to affect the mating rituals of some birds. Research has also shown that noise pollution in the oceans alters the behavior and communication of marine life such as dolphins and whales that depend on sound for daily activities. And…

“Parc National La Visite is one of the few remaining refuges for Haiti’s once-remarkable biodiversity. It is also the only refuge for over 1,000 desperately poor families, the poorest people I have encountered anywhere on this planet. Naked children with bloated stomachs stood next to pine-bark lean-tos and waved shyly to me as I walked through the forest. Their parents…

This post contributed by Monica Kanojia, Administrative Assistant/Governance for ESA. Amphibians have been around for hundreds of millions of years. They have survived numerous extinction events and yet somehow, in the past two decades, their numbers have been in severe decline. The population changes have been linked to many factors, including climate change and disease, habitat destruction and water pollution….
