Voices: The confounding economics of natural disasters

In the hours (not days) after the enormous earthquake hit Japan on March 11, before it was even known that the Fukushima power plant had been badly disabled and well before the scope of the mortality and damage had been assessed, the Japanese yen rapidly appreciated in value. The G7 nations moved to quickly stabilize the yen — not to prevent it from falling, but to prevent it from further appreciating.

Voices: What does "The Nation's Report Card" tell us about science education?

In President Barack Obama’s State of the Union speech in January, he emphasized the need for more scientists, mathematicians and engineers in the U.S. workforce. But the latest national assessment of science education in the U.S. appears to offer little hope for our next generation of scientists. Still, the results provide some insight on the state of science education in this country — information that we can use to improve our schools.

Voices: Nuclear plants and natural disasters: Fukushima's fallout

Before it happened, it was hard to imagine that a combined megaquake and tsunami in Japan could cascade to a nuclear disaster. Yet that’s exactly what happened at the Fukushima Daiichi (Number 1) nuclear power plant, 220 kilometers northeast of Tokyo, last month. This incident has put Japan’s nuclear policy in the spotlight, but its implications go far beyond a single country.

Voices: What happened at Fukushima?

The Fukushima Daiichi power plant located in the port town of Okuma in the Fukushima Prefecture, northeast Japan, has six boiling-water-type nuclear reactors supplied by General Electric (units 1, 2 and 3), Toshiba (units 3 and 5) and Hitachi (unit 4) for

Strategies to meet our water and energy needs: Insight from a Texas "Treemap"

"This is our generation’s Sputnik moment,” declared President Barack Obama in the 2011 State of the Union address, challenging the nation to pursue a future of cleaner energy.

As we did a generation ago, we now face significant challenges — challenges that need to be met sooner rather than later to protect and grow our economy, build energy autonomy and preserve our resources for future generations. These challenges center on two resources: energy and water.

Tracking trace elements and isotopes in the oceans

A report from the GEOTRACES cruise across the Atlantic

For decades, scientists have been trying to piece together the enormously complicated puzzle that is the ocean. They have collected many different kinds of information, from trace elements like iron to tritium isotopes, from many different parts of the ocean. Bringing together these disparate pieces to form a more complete picture is crucial to understanding how human activities, the marine food web, the global carbon cycle and the circulation of seawater are all interconnected.

Geomedia: Zombie Science? New Madrid and "Disaster Deferred"

During the winter of 1811-1812, three strong earthquakes between magnitude 7 and 8 rocked the New Madrid seismic zone, which runs through parts of eastern Missouri and northeastern Arkansas. The quakes opened deep fissures, destroyed forests and lakes, and produced intense ground shaking that liquefied the soil, turning the land to the consistency of jelly across an area of 10,000 square kilometers.

Bacteria back from the brink

Thousand- and million-year-old microbes found living in salt crystals:  Could they also exist on other planets?

In 1993, “Jurassic Park” thrilled the world with the idea that dinosaurs could be resurrected from bits of DNA preserved in mosquitoes trapped in ancient amber. In the 18 years since the movie came out, scientists have been finding that parts of this scenario are closer to reality than anyone ever imagined.

The rise of community remote sensing

If you ask someone involved in community remote sensing to define the emerging field, the most likely response will be a chuckle followed by “That’s a hard question to answer…”
