EARTH Magazine: The Most Dangerous Fault in America

EARTH Magazine

From EARTH Magazine, 05/23/2016  --  When people think of dangerous faults in America, the the San Andreas probably comes to mind first. But another potentially greater threat lurks in the East Bay region of Northern California, just a stone's throw from San Francisco and the tech hub of Silicon Valley: the Hayward Fault. In the June issue, EARTH Magazine guest author Steven Newton lays out just what is at risk, and what to expect when an earthquake strikes on what may be the most dangerous fault in America.

EARTH Magazine: Did the Medieval Warm Period Welcome Vikings to Greenland?

EARTH Magazine

From EARTH Magazine, May 16, 2016  --  What is known: Vikings sailed to Greenland. They homesteaded there for a few hundred years, and likely experienced multiple famines. Many died. Some returned to European shores. And all of this happened during a time in Europe known to geoscientists as the Medieval Warm Period. The warmer, milder conditions that defined this time eventually ended too. 

EARTH Magazine: Growth Rings in Rocks Reveal Past Climate

EARTH Magazine

From EARTH Magazine, May 5, 2016  --  For years, scientists have used mineral, sediment and ice layers, deposited intermittently throughout geologic time, to track the global climate record. These can come from caves, lakes, the oceans and ice sheets. But over the course of the last decade a new method has been developed that presents an opportunity for geoscientists to assess global climate history in almost any arid landscape.

NSF: Researchers find that Earth may be home to 1 trillion species

National Science Foundation

From NSF, May 2, 2016  --  Largest analysis of microbial data reveals that 99.999 percent of all species remain undiscovered

Earth could contain nearly 1 trillion species, with only one-thousandth of 1 percent now identified, according to the results of a new study.

The estimate, based on universal scaling laws applied to large datasets, appears today in the journal Proceedings of the National Academy of Sciences. The report's authors are Jay Lennon and Kenneth Locey of Indiana University in Bloomington, Indiana.

2016 Teacher Appreciation Week - a message from the National Science Foundation

National Science Foundation

During Teacher Appreciation Week, the National Science Foundation wants to acknowledge and celebrate the amazing commitment and profound work of STEM teachers across grades preK-12. Attached is a letter from the Assistant Director of the Directorate for Education and Human Resources at the National Science Foundation, Joan Ferrini-Mundy, who is taking the time to recognize the wonderful pool of dedicated STEM teachers we have here in Pennsylvania and across the United States.

 

EARTH Magazine: Where Fire Freezes - All Eyes, Ears and Instruments on Iceland’s Volatile Volcanoes

EARTH Magazine

From EARTH Magazine, 03/31/2016  --  Iceland is located in the North Atlantic straddling a mid-ocean ridge and possibly riding over a Hawaiian-style hot spot. This makes it is a prime geological environment for volcanoes: Iceland has more than 100 volcanoes, 33 of which are active. Iceland is also home to examples of every type of volcano on Earth, each with its own eruptive pattern. Thus, the island nation presents a special challenge to volcanologists as well as serving as an ideal natural laboratory for studying how volcanic processes evolve.
