ANN ARBOR— A dollop of hair gel might not look like much, but Michigan Engineering researchers have found that it’s a labyrinth of chambers and domes, constructed by the particles inside. These structures allow the gel to hold its shape and determine how much pressure it can withstand before it starts to flow.
While manufacturers currently use trial and error to develop gels with a particular degree of solidity, this discovery could provide a way to design gels for particular applications. (more…)
The Utica Shale contains about 38 trillion cubic feet of undiscovered, technically recoverable natural gas (at the mean estimate) according to the first assessment of this continuous (unconventional) natural gas accumulation by the U. S. Geological Survey. The Utica Shale has a mean of 940 million barrels of unconventional oil resources and a mean of 208 million barrels of unconventional natural gas liquids.
The Utica Shale lies beneath the Marcellus Shale, and both are part of the Appalachian Basin, which is the longest-producing petroleum province in the United States. The Marcellus Shale, at 84 TCF of natural gas, is the largest unconventional gas basin USGS has assessed. This is followed closely by the Greater Green River Basin in southwestern Wyoming, which has 84 TCF of undiscovered natural gas, of which 82 TCF is continuous (tight gas). (more…)
A fossil unearthed in Great Britain may end a long-running debate about the mollusks, one of life’s most diverse invertebrate groups: Which evolved first, shelled forms like clams and snails, or their shell-less, worm-like relatives?(more…)
EAST LANSING, Mich. — Research by Michigan State University astronomers has scientists re-thinking the fates of black holes, particularly in groups of stars known as globular clusters.(more…)
An online study of eligible voters around the country revealed that preferences for whites over blacks among the least politically-partisan voters are strong enough to have substantial impact on their presidential candidate preference.
Among these voters, race biases against Barack Obama could produce as much as a 20 percent gap in the popular vote in a contest that would otherwise be equal. (more…)
A lot is up for grabs this November in America—the presidency of the United States, for one. Not to mention a third of U.S. Senate seats, all seats in the U.S. House, and state-level amendments on issues ranging from voter ID to same-sex marriage (Minnesota has both on the ballot).
But almost six million Americans will sit this one out because of something they’ve done. They’re felons—perpetrators, at some point in their lives, of a serious crime. (more…)
