By studying samples from carbon-rich meteorites, scientists with NASA's Goddard Space Flight Center say they have discovered that the building blocks of life can be created and maintained in extreme heat, not just in cooler conditions as had previously been believed. In a Friday press release, the U.S. space agency reports that experts from the Greenbelt, Maryland facility's Astrobiology Analytical Laboratory studied 14 samples and discovered "minerals that indicated they had experienced...

Highlights new research, and offers solutions for a nitrogen-soaked world The nitrogen cycle has been profoundly altered by human activities, and that in turn is affecting human health, air and water quality, and biodiversity in the U.S., according to a multi-disciplinary team of scientists writing in the 15th publication of the Ecological Society of America´s Issues in Ecology. In “Excess Nitrogen in the U.S. Environment: Trends, Risks, and Solutions,” lead author Eric...

Interdisciplinary panel reviews US nitrogen pollution trends, risks, and mitigation strategies Nitrogen is both an essential nutrient and a pollutant, a byproduct of fossil fuel combustion and a fertilizer that feeds billions, a benefit and a hazard, depending on form, location, and quantity. Agriculture, industry and transportation have spread nitrogen liberally around the planet, say sixteen scientists in the latest edition of ESA's Issues in Ecology series, "Excess Nitrogen in the U.S....

A team of researchers at the California Institute of Technology (Caltech) has devised a new method for making complex molecules. The reaction they have come up with should enable chemists to synthesize new varieties of a whole subclass of organic compounds called nitrogen-containing heterocycles, thus opening up new avenues for the development of novel pharmaceuticals and natural products ranging from chemotherapeutic compounds to bioactive plant materials such as morphine. The...

Nitrogen derived from human activities has polluted lakes throughout the Northern Hemisphere for more than a century and the fingerprint of these changes is evident even in remote lakes located thousands of miles from the nearest city, industrial area or farm. The findings, published in the journal Science Dec. 16, are based on historical changes in the chemical composition of bottom deposits in 36 lakes using an approach similar to aquatic archeology. More than three quarters of the...
