Plastic upcycling method turns food packaging into faster-degrading materials

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

Antarctica's Ross Ice Shelf and the West Antarctic Ice Sheet may have been far smaller during one of Earth's most recent warm periods, according to a new study that traced the origin of ancient dust preserved in Antarctic ice. Previous modeling studies suggest that the melting of the West Antarctic Ice Sheet could raise global sea levels by between three and five meters.

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.
