Spotlight on UCORE projects

The National Science Foundation-funded Undergraduate Catalytic Outreach and Research Experience (UCORE) program ran from 2007 to 2012 and involved 132 students from six different community colleges in Oregon. During the five years of the UCORE program, groups of three to six community college students from each campus spent 10 weeks in the summer on the University of Oregon campus, working on projects alongside graduate students and faculty in chemistry, geological sciences and physics research groups. Listed below are some of the projects in which the students were involved.

Apollo science, 40 years later: Scientists reopen a lunar cold case

Today’s lunar scientists are like detectives who reopen old criminal cases and examine them anew with modern instruments and techniques like DNA analysis. Armed with data and analytical techniques not available in the 1970s, scientists are re-examining Apollo moon rocks and learning more than ever before about our nearest celestial neighbor.

Releasing a flood of controversy on the Colorado River

Since the completion of the Glen Canyon Dam in 1963, the once warm and muddy Colorado River has run clear and cold, with a drastically altered ecosystem. A new plan to release regular, intentional floods — to resupply sediment and restore species habitat — aims to reverse the damage done to the Grand Canyon’s natural systems over the last 50 years.

Sinkholes: Florida grapples with the wonders of the not-so-deep

This story was printed in August 2010. In response to the tragic sinkhole event in Tampa, Fla., on March 1, we are reposting this story.

Sinkholes are a natural part of Florida’s landscape, forming when rainwater levels fluctuate. They've occurred naturally for millions of years and they haven’t been a big problem for humans until recently: Florida’s population has increased from fewer than 8 million in the 1970s to just shy of 20 million today — and farmers, snowbirds and Mother Nature have begun to engage in an increasingly acrimonious water war. The addition of humans to the landscape has made the situation increasingly volatile. Now, sinkholes open up seemingly — or literally — overnight. When a sinkhole opened up in a cow pasture, few people cared, but now if one opens up under somebody’s house or under Interstate 4, we pay attention.

Setting sail on unknown seas: The past, present and future of species rafting

The 2011 Japanese tsunami set adrift tons of debris, some of it carrying live plants and animals that landed in North America more than a year later. It isn’t the first time species have traveled the globe on ersatz rafts, and it won’t be the last. But it is concerning.

Drinking toilet water: The science (and psychology) of wastewater recycling

Would you drink water that came from a toilet? The imagery isn’t appealing. Even knowing that the water, once treated, may be cleaner than what comes out of most faucets, many people are disgusted by the idea. But in places like Singapore and Namibia, limited supplies of freshwater are being augmented by adding highly treated wastewater to their drinking water. As climate change and population growth strain freshwater resources, such strategies are likely to become more common around the world, and in the United States.

The dangers of solar storms: That which gives power can also take it away

Were a massive solar storm to strike Earth, the impacts could rival or exceed the worst natural disasters humans have ever faced. In last month’s issue of EARTH, we explored what is known about solar activity, the sun and its interaction with Earth. This month, we examine the possible effects of solar activity and the vulnerability of power grids and satellites, as well as what is being done to reduce that vulnerability.

How strong was the Carrington Event?

NASA has described the magnetic field of the coronal mass ejection (CME) associated with the 1859 Carrington Event, the largest solar storm ever detected, as “extremely intense” relative to other CMEs. The amount of plasma it ejected is difficult to estimate, but more important in determining its strength is how fast it arrived.

Superquakes, supercycles, and global earthquake clustering: Recent research and recent quakes reveal surprises in major fault systems

A number of recent big earthquakes around the world have humbled many earthquake researchers. The March 2011 magnitude-9 superquake off Tohoku, Japan, and the December 2004 magnitude-9-plus temblor off Sumatra were both far larger than what scientists expected those fault systems to produce. Based on these quakes, and on recent research that contradicts long-held paradigms, it is becoming clear that the types and sizes of large earthquakes that a given fault system is capable of producing remain poorly known for most major fault systems.

Travels in Geology: Famous fossils and spectacular scenery at British Columbia's Burgess Shale

Of all the famous fossil localities in the world, perhaps none is as widely celebrated as British Columbia’s Burgess Shale. High in the Canadian Rockies, the Burgess Shale contains some of the oldest and most exquisitely detailed fossils of early life on Earth. Visiting the Burgess Shale requires some preparation — you must hire a guide and hike 22 kilometers at high elevation — but for a fossil enthusiast, the payoff is worth every step.
