Lower air pollution levels saved an estimated 5,660 lives in New York State in 2012, compared to 2002 levels, according to a new study.
NASA's Aqua satellite passed over the Sea of Japan and provided forecasters with a visible image of Tropical Storm Francisco as it was transitioning into an extra-tropical cyclone.
In a Plants, People, Planet study, researchers investigated the evolution of the two most prevalent orchid viruses using information representing their global distribution. The study revealed that considerable international trade of cultivated orchids has effectively 'homogenized' the genetic diversity of the viruses. In other words, the two viruses have displayed few genetic differences since their first emergence, across countries and host plants.
Scientists are increasingly warning that prescription drugs can affect wildlife and ecosystems when they find their way into the environment. In a new Environmental Toxicology and Chemistry study, investigators found that the anxiety and depression drug Escitalopram -- at concentrations similar to those measured in the environment -- can inhibit fish foraging and eating behavior.
A study in 18 European countries suggests that current WHO air quality guidelines for NO2 do not provide sufficient protection for children.
After years of federally mandated protection, scientists see signs that this once ecologically fertile area known as the Hawaiian-Emperor Seamount Chain is making a comeback.
Researchers developed a first-of-its-kind, comprehensive model that simulates how environmental factors, including increasing sea temperatures and overfishing, impact levels of methylmercury in fish. The researchers found that while the regulation of mercury emissions have successfully reduced methylmercury levels in fish, spiking temperatures are driving those levels back up and will play a major role in the methylmercury levels of marine life in the future.
Groundwater maintains vital ecosystems and strongly influences water and energy budgets. Although at least 400 million people in sub-Saharan Africa depend on this valuable resource for their domestic water needs, the processes that sustain it and their sensitivity to climatic variability, are poorly understood. IIASA contributed to a study that looked into climate impacts on groundwater in light of changing climatic patterns in Africa.
A famous experiment in 1953 showed that amino acids, the building blocks of proteins, could have formed spontaneously under the atmospheric conditions of early Earth. However, just because molecules could form doesn't mean that the process was likely. Now, researchers reporting in ACS Central Science have demonstrated that energetically feasible interactions between just two small molecules -- hydrogen cyanide and water -- could give rise to most of the important precursors of RNA and proteins.
Marine microbes with a special metabolism are ubiquitous and could play an important role in how Earth regulates climate.
