Antibacterial clays could fight superbugs

Clays with antibacterial properties found near Crater Lake in Oregon could eventually lead to new agents in the fight against antibiotic-resistant superbugs like methicillin-resistant Staphylococcus aureus, better known as MRSA, according to a new study.

Geologic Column: What geoscientists can learn from TED Talks

TED talks have become an international — and Internet — phenomenon. The presentations are pithy, conversational, focused and entertaining; they are often inspirational and sometimes very personal. Geoscientists — whether presenting conference papers, classroom lectures or presentations for general audiences — can learn a lot from TED talks, especially from the structure and guidance applied to preparing the talks.

Comment: Preparing for the volcano in your backyard: New Zealand sets an example

Preparing and planning for a potential volcanic eruption can help communities cope with fallout and manage the human response when eruptions do happen. Auckland, New Zealand, is working on just such a plan that can serve as an example to other cities facing potential volcanic hazards now or in the future.

Mineral Resource of the Month: Strontium

Strontium occurs commonly in nature, ranking as the 15th most abundant chemical element on Earth. Only two minerals contain sufficient strontium, however, to be used commercially to produce strontium compounds: Strontianite (strontium carbonate) has a higher strontium content, but celestite (strontium sulfate) is by far the most abundant strontium mineral.

Down to Earth With: Ecologist Chris Field

Last summer, the American Geophysical Union honored Chris Field, founding director of the Carnegie Institution’s Department of Global Ecology, with its annual Roger Revelle Award, which recognizes “outstanding contributions in atmospheric sciences, atmosphere-ocean coupling, atmosphere-land coupling, biogeochemical cycles, climate or related aspects of the Earth system.”

Geomedia: Books: Are we causing a sixth extinction?

Last year, Elizabeth Kolbert released her latest excellent book. Her previous volume, “Field Notes from a Catastrophe,” set a high bar for accessible, accurate science writing about environmental issues, but in my opinion, “The Sixth Extinction” surpasses it in several regards. Readers of this magazine will appreciate its solid geologic grounding and perspective, with entire chapters devoted to the end-Ordovician and end-Cretaceous extinctions, as well as sections on the principles of evolution and Earth history. Climate change, the focus of her earlier book, looms large here too, though it is just one of the many threats to the survival of our biosphere that Kolbert covers.

Geocorps America: Putting geoscientists to work on federal lands

GeoCorps America has been putting geoscience students, recent graduates, and professional and retired geoscientists to work on short-term projects on federal lands since 1997. Today, GeoCorps encompasses projects in more than 60 national parks, 15 national forests and 15 public lands; and it is still growing.
