Ancient dust points to retreat of West Antarctic Ice Sheet during last warm period

Scientists have discovered a way to convert widely used plastics into new materials with distinct properties that degrade more rapidly. Applying this new process to upcycle existing plastics—such as those used for food packaging and in 3D printing—could contribute to tackling global plastic pollution issues, researchers say.

From the Kleines Nesthorn to Pizzo Cengalo, the Alps appear to be crumbling. Permafrost researcher Robert Kenner has penned a summary explaining the role that thawing permafrost and melting glaciers play—or don't play—in this process.

If you live near an interstate or busy roadway in Tampa, you can literally wipe the grime from auto exhaust off your windows. Imagine breathing all that stuff into your lungs. Such pollution is a serious issue as traffic continues to grow and researchers at USF's College of Public Health (COPH) want to improve ways to monitor airborne contaminants and build more robust data on their levels and impact. The information on traffic-related air pollution (TRAP) also may pave the way in planning for c

In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry. This model suggests that every living organism can be traced back to a distant common ancestor. However, viruses—which are not made of cells, but consist only of genetic material—are not part of this traditional cellular tree of life, raising important questions about their origin and evolution.
