Since 1859, more than 325,000 oil and gas wells have been drilled in the state, and many areas still bear the scars of strip-mining for coal. Now the latest energy boom in on. Thousands of feet below the surface are the Marcellus and Utica shale formations and their largely untapped reserves of natural gas.
Deep shale gas is tapped through the process known as hydraulic fracturing, or fracking, and since 2004 nearly 3,000 of these new wells have been drilled in Pennsylvania. That’s just a tiny fraction of the state’s conventional oil and gas wells. However, because shale gas is so deep and fracking involves handling massive amounts of water, shale gas development leaves a bigger footprint on the landscape than does conventional drilling.
The latest issue of CSA News explores the potential impact of fracking on Pennsylvania’s forests as well as how the most troubling effects might be avoided or mitigated. Researchers have found, for example, that the heaviest gas development is occurring in the Susquehanna River basin—the source of more than half the water flowing into the embattled Chesapeake Bay. And nearly 25% of shale gas wells have gone into Pennsylvania’s last remaining tracts of unbroken, “core” forest, which is among the last intact forest in the entire Northeast, as well.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
