If the fate of carbon is a test that planet Earth is taking right now, one of the answer keys is likely to be found in soil, where microorganisms—which account for nearly 15 percent of global biomass, by some estimates—eat, store and respire carbon and other nutrients. As Earth warms, how these microbes change the way they live will have potentially big consequences for where the carbon goes.
Now, a team… Read more
As the threat of global warming grows—and with it, the specter of more extreme conditions such as wildfires, droughts and tropical storms—cities across the U.S. are developing policies to reduce their emissions of greenhouse gases, chiefly carbon dioxide (CO2). Even though many local governments are committed to these goals, however, the emissions data they have… Read more
Evolutionary biologists have long puzzled over how new traits emerge in nature, largely because much of the evolutionary information available is from the distant past. To learn more about how genes influence evolution, these researchers study organism phenotypes—the observable characteristics of an organism that are influenced by genetics and… Read more
Native Americans have the lowest rate of university enrollment and graduation rates of any group in the United States—and in STEM fields, they represent only 0.5 percent of students nationwide. Another major hurdle for Native American populations is health-related. Those living on tribal lands experience a disproportionate rate of environmentally-associated health issues such as… Read more
St. Lawrence Island, just south of the Bering Strait in Arctic Alaska, is one of the most isolated places on the planet. Wild, mountainous and remote, the island is inhabited by 1,600 indigenous Yupik Eskimos who subsist by hunting and fishing.
Although the island’s natural environment may appear pristine, residents are exposed to high levels of persistent organic pollutants—toxic chemicals that remain in the… Read more
A new paper published in PLOS Pathogens by a team of researchers comprised of Bruce Hungate and Ben Koch from Northern Arizona University; Lance Price from George Washington University and the Translational Genomics Research Institute; and Gregg Davis and Cindy Liu from George Washington University outlines the critical need for further research into the nature of colonizing opportunistic pathogens, or… Read more
