Study Casts Doubt on Climate Benefit of Biofuels from Corn Residue

Published: April 21, 2014.
Released by University of Nebraska-Lincoln  

Lincoln, Neb., April 20, 2014 -- Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change. The findings by a University of Nebraska-Lincoln team of researchers cast doubt on whether corn residue can be used to meet federal mandates to ramp up ethanol production and reduce greenhouse gas emissions.

Africa Could Be the Answer to Delaying 'Peak Grain'
Lincoln, Nebraska, Sept. 28, 2015 -- Agricultural yields could more than triple in a number of African countries, suggesting that tremendous improvements in food security are possible, according to new findings by the Global Yield Gap and Water Productivity Atlas.

Physicists Defy Conventional Wisdom to Identify Ferroelectric Material
Lincoln, Neb., Sept. 17, 2015 - A team of physicists has defied conventional wisdom by inducing stable ferroelectricity in a sheet of strontium titanate only a few nanometers thick. The discovery could open new pathways to find new materials for nanotechnology devices, said Alexei Gruverman, a University of Nebraska-Lincoln physics and astronomy professor who worked on the research.

Study: 2 Major US Aquifers Contaminated by Natural Uranium
Nearly 2 million people throughout the Great Plains and California above aquifer sites contaminated with natural uranium that is mobilized by human-contributed nitrate, according to a study from the University of Nebraska-Lincoln. Data from roughly 275,000 groundwater samples in the High Plains and Central Valley aquifers show that many Americans live less than two-thirds of a mile from wells that often far exceed the uranium guideline set by the Environmental Protection Agency.

Study Is First to Quantify Global Population Growth Compared to Energy Use
Lincoln, Neb., July 24th, 2015 -- If you've lived between the year 1560 and the present day, more power to you. Literally. That's one of several conclusions reached by University of Nebraska-Lincoln ecologist John DeLong, who has co-authored the first study to quantify the relationship between human population growth and energy use on an international scale.

New Study: Roadside Bomb Blasts May Cause More Brain Damage Than Previously Recognized
Lincoln, Neb., June 9th, 2015 -- By accounting for a rush of blood to the head, University of Nebraska-Lincoln engineers have found that blast waves from concussive explosions may put far greater strain on the brain than previously thought. The researchers have authored a study examining, for the first time, how blood vessel networks affect the potential incidence of traumatic brain injury from improvised explosive devices that blanket combat zones throughout the Middle East.

Chemists Strike Nano-gold: 4 New Atomic Structures for Gold Nanoparticle Clusters
Lincoln, April 28, 2015 -- Arranging gold, atomic staples and electron volts, chemists have drafted new nanoscale blueprints for low-energy structure capable of housing pharmaceuticals and oxygen atoms.

Would You Rather Work for Megatron Or Optimus Prime?
Lincoln, Neb., April 27, 2015 -- New research by the University of Nebraska-Lincoln's Peter Harms shows there is more than meets the eye when it comes to the impact of Saturday morning cartoons. The research examines how fantasy-based stories -- specifically those from the popular 1980s "The Transformers" cartoon and movie -- can shape children's perceptions of what behaviors are associated with effective leadership. It also could provide a basis for workplace-training programs.

University of Nebraska-Lincoln, US Navy Develop Next-gen Temperature Sensor to Measure Ocean Dynamics
Lincoln, Neb., April 6, 2015 -- UNL engineers and the U.S. Naval Research Laboratory have designed a next-generation temperature sensor set to improve the measurement of oceanic dynamics that shape marine biology, climate patterns and military operations. The fiber-optic sensor can register significantly smaller temperature changes at roughly 30 times the speed of existing commercial counterparts, said co-designer Ming Han, associate professor of electrical engineering.
