New study traces Io's volcanic tides

PhysOrg — “The magma in Io’s crust takes time to flow,” said Francis Nimmo, a geophysicist at the University of California Santa Cruz and co-author on the new paper. “If you squeeze and stretch the crust rapidly, nothing happens; but if you squeeze and stretch it more slowly, the magma has time to move far enough to fill a volcanic conduit, causing an eruption. It’s similar to the way you can run on wet sand, but if you walk slowly your feet sink.”

A study in Elkhorn Slough reveals the increasing threat of climate change to salt marshes.

Monterey County Weekly — Between crabs burrowing into the marshes and rising oceans, a recent study led by Elkhorn Slough National Estuarine Research Reserve in collaboration with NOAA’s National Estuarine Research Reserve System found that it is not crabs alone that are potentially causing problems for the nation’s salt marshes.

Sea of Galilee earthquakes triggered by excessive water pumping

Science Magazine — Researchers have long known that humans can cause earthquakes by injecting fluid into the ground—a technique used in hydraulic fracturing, or fracking, to break open rocks and release natural gas or petroleum. Pumping water into geothermal vents to generate steam for heating and electricity has also triggered temblors. But earthquakes set off by pumping fresh water out of underground aquifers haven’t received much attention, says study co-author Emily Brodsky, a seismologist at the University of California, Santa Cruz. “This is not the first example of groundwater extraction triggering earthquakes, but it’s uncommon,” she says.

NMR structure of a key anticoagulant protein may help prevent thrombosis

Medical Xpress — A collaboration between researchers from Brazil and the United States may open new avenues for the treatment of thrombosis, the leading cause of death among cancer patients. In a study to be published in Blood, the scientists describe the Ixolaris structure, an important anticoagulant protein found in tick saliva, and its interaction with Factor Xa, a key enzyme in the process of blood clotting.
