Some manmade chemicals feature bonds so strong they could last forever. And that's a life-threatening problem.
In a uranium-based compound once dismissed as boring, scientists watched superconductivity arise, perish, then return to life under the influence of high magnetic fields.
Precise determination of hemoglobin sequence and subunit quantitation from human blood for diagnosis of hemoglobin-based diseases.
Scientists will be able to apply the technique to characterize similar molecules, helping develop vaccines and drugs to treat bacterial infection.
Researchers have discovered a new method to create encapsulated carbon nanomaterials that contain fluorine. Known as fullerenes, these nanocages are promising candidates for clean energy applications.
Water samples collected from the heart of Africa contain clues about carbon cycling worldwide.
Molecular fossils of chlorophyll (called porphyrins) more than 1.1 billion years old find suggest that photosynthesis began 600 million years earlier than previously established.
Vincent Salters joins the elite ranks of American Geophysical Union fellows.
Protein oxidative damage is a common occurrence in a number of diseases, including cancer, neurodegenerative, and cardiovascular disease. Yet, little is known about its contribution to these illnesses. We developed a new technique, utilizing an infrared laser in combination with a mass spectrometer, to selectively identify sites of oxidation in complex protein mixtures. This sensitive and rapid platform may outperform current techniques and thus shed light on the involvement of oxidative damage in each of these diseases.
Members of a sprawling science team piece together the puzzle of biochar, a promising tool in the fight against global warming.
