Innovative Way to Understand Nature of an Entire Tiny Particle

University of New Hampshire

New research from the University of New Hampshire has led to the development of a novel technique to determine the surface area and volume of small particles, the size of a grain of sand or smaller. Due to their tiny size, irregular shape and limited viewing angle, commonly used microscopic imaging techniques cannot always capture the whole object’s shape often leaving out valuable information that can be important in numerous areas of science, engineering and medicine.

Forget the Red Hot Blob: Volcanic Zircon Crystals Give a New View of Magma

Michigan Technological University

The classic red teardrop of magma underneath a volcano peak is too simplistic. Magma chambers are chemically and physically complex structures that new evidence, published this week in Science, suggests may be cooler and more solid than expected.

Death by Volcano?

Washington University in St. Louis

The discovery of anomalously high levels of mercury in rocks from the Ordivician geological period has led to a new interpretation of the ensuing mass extinction. A sequence of disturbances may have led to catastrophic cooling by reflective sulfate aerosols injected into the atmosphere by massive volcanism. The finding is important since aerosol cooling is under consideration as a way to temper global warming.

Eruptions Examiner

University of Iowa

University of Iowa volcanologist Ingrid Ukstins spent two weeks collecting samples from Yasur, a continuously erupting volcano on Tanna, an island in the remote South Pacific archipelago of Vanuatu, to study its chemical composition and determine how the gasses it produces may be affecting people who live nearby.

Volcano Breath: Measuring Sulfur Dioxide From Space

Michigan Technological University

A number of volcanoes around the world continuously exhale gases. Of these, sulfur dioxide is the easiest to detect from space and now researchers have created the first global map of SO2 plumes from volcanoes.

National Geographic Supports Volcano Research in Chile

Boise State University

As planning continues for humanity’s first visit to Mars, scientists still have much to learn about the planet’s physical makeup. By comparing current satellite images to similar shots of Earth, they are coming to understand how volcanic activity shaped the Red Planet, and extrapolating lessons learned to address concerns closer to home.
