A chemical signature recorded on the ear bones of Chinook salmon from Alaska’s Bristol Bay region could tell scientists and resource managers where they are born and how they spend their first year of life. This bone, called an otolith, accumulates layers as a fish grows, similar to trees. These “growth rings” are produced throughout […]

So what’s the big deal about successfully growing Arctic cod in a laboratory? It represents another step forward toward understanding how these “bellwether” fish in the Arctic marine ecosystem may fare with a warming ocean and climate change. It also opens up a new frontier to study cod development in a laboratory setting. Up until […]
SALT LAKE CITY – University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber. The hot rock in the newly discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand […]
