A colossal magma system has been hiding beneath Tuscany

Scientists have discovered an enormous body of magma deep beneath Tuscany, even though the region shows few of the surface clues typically associated with such systems. Using a seismic imaging method called ambient noise tomography, researchers detected approximately 6,000 km3 of volcanic fluids buried 8 to 15 km below the…

Scientists catch a “jumping gene” mid-leap between species

Jumping genes are genetic parasites found in bacteria, plants, animals, and humans. They can be released inside cells as small RNA molecules from ribonucleic acid (RNA), then use specialized mechanisms to insert themselves into new locations within the genetic material. These movements can give cells new traits, making jumping genes…
