Scientists gather in Oregon to decide next steps of mid-ocean ridge exploration
More than 130 ocean scientists from the U.S. and overseas will meet in Newport, Oregon, September 22-24, to plan a new decade of research into the geology, chemistry and biology of Earth's mid-ocean ridge system. (1999-09-17)

From 'science from above' to 'science in the community'
For the first time in the 130-year history of international polar years, people living in polar regions were not just objects of study -- they led studies. (2012-02-18)

Reading the Earth's LIPS
An international team of scientists including University of Sydney geophysicists Professor Dietmar Müller, Dr. Simon Williams and Dr. Maria Seton from the School of Geosciences have found a novel way to 'read the Earth's LIPS' -- its Large Igneous Provinces. Their findings are reported in a Nature Geoscience article in which they show for the first time that LIPS have a close working relationship with underwater mountain ranges called mid-ocean ridges.

Stellar pinwheels at our Galaxy's core
Astronomers have finally learned the identity of a mysterious (2006-08-18)

How the Earth's Pacific plates collapsed
Scientists drilling into the ocean floor have for the first time found out what happens when one tectonic plate first gets pushed under another. The international expedition drilled into the Pacific ocean floor and found distinctive rocks formed when the Pacific tectonic plate changed direction and began to plunge under the Philippine Sea Plate about 50 million years ago.

A study by MSU scientists will help specify the models of the Earth atmosphere circulation
A team of scientists from the Institute of Mechanics, MSU demonstrated how random fluctuations in the rotation speed and noises influence the number of vortexes in the Couette spherical flow. It turned out that the level of noise and the flow regime have a complicated nonlinear correlation between them. The new data will help to develop more exact models of natural flows including the atmospheric circulation. The results of the work were published in the Chaos journal. (2018-08-19)

Dynamic earth processes across time and space
The dynamics of Earth are discussed in this new batch of GSA Bulletin papers posted online April 6. Topics include the link between wildfire-flooding events and the supply of sand to beaches, with specific focus on a coastal California watershed; high-pressure metamorphism in the mountains of northwest China; generation of the Gold Hill shear zone and widespread tectonism in the Appalachian mountain belt; and the nature of magma-filled fractures in the earth.

June GEOSPHERE media highlights
The June issue of GEOSPHERE, published by the Geological Society of America, is now available online. Topics of interest include common ground in the disagreement between mantle plume and lithospheric mantle-lower crust delamination models; a USGS Great Basin Paleontological Database filled with 150 years of fossil data; laser rangefinders versus terrestrial laser scanners and digital cameras in three-dimensional modeling; and contaminant sources of northern Mexico's Rio Conchos, including the effects of human activities.

Platinum cages
John A. Shelnutt and his team at the Sandia National Laboratories and the University of New Mexico in Albuquerque as well as the University of Georgia in Athens has developed a new technique for the production of large porous platinum nanocages with a broad spectrum of potential biomedical, catalytic and optical applications.

Modeling early meteorite impacts on the moon
A detailed reconstruction of meteorite impacts resolves a longstanding problem and gives new insight into how the moon formed. (2019-07-10)

Diamonds found with gold in Canada's Far North offer clues to Earth's early history
The presence of diamonds in an outcrop atop an unrealized gold deposit in Canada's Far North mirrors the association found above the world's richest gold mine, according to University of Alberta research that fills in blanks about the thermal conditions of Earth's crust three billion years ago.

When continents break it gets warm on Earth 
The concentration of carbon dioxide (CO2) in the atmosphere determines whether the Earth is in greenhouse or ice age state. Before humans began to have an impact on the amount of CO2 in the air, it depended solely on the interplay of geological and biological processes, the global carbon cycle. This study shows that the break-up of continents - also known as rifting -- contributed significantly to higher CO2 concentrations in the atmosphere. (2017-11-13)

New treatment for hepatitis C
A statin drug used to lower cholesterol found to stop hepatitis C, especially in patients resistant to standard treatment. (2008-05-14)
