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.

Study Confirms: Forms of HIV Can Cross from Chimps to Humans
Lincoln, Nebraska, July 22, 2016 - No one knows exactly how it happened. It may have entered through a cut or bite wound, the blood of a chimpanzee seeping into an exposed fingertip or forearm or foot. But in the early 1900s, probably near a West African rainforest, it's thought that a hunter or vendor of bush meat - wild game that can include primates - acquired the first strain of a simian immunodeficiency virus that virologists consider the ancestor of HIV.

Researchers Build Molecule That Could Significantly Reduce Brain Damage in Stroke Victims
Research teams separated by 14 hours and 9,000 miles have collaborated to advance prospective treatment for the world's second-leading cause of death. University of Nebraska-Lincoln chemists partnered with medical researchers from the National University of Singapore to develop a molecule that can inhibit an enzyme linked with the onset of stroke.

A New Form of Frozen Water?
Lincoln, Neb., Feb. 12, 2016 -- Amid the season known for transforming Nebraska into an outdoor ice rink, a University of Nebraska-Lincoln-led research team has predicted a new molecular form of the slippery stuff that even Mother Nature has never borne. The proposed ice, which the researchers describe in a Feb. 12, 2016 study in the journal Science Advances, would be about 25 percent less dense than a record-low form synthesized by a European team in 2014.

Conductive Concrete Could Keep Roads Safer in Winter Weather
Lincoln, Neb., Jan. 22, 2016 -- A 200-square-foot slab of seemingly ordinary concrete sits just outside the Peter Kiewit Institute as snowflakes begin parachuting toward Omaha on a frigid afternoon in late December. The snow accumulates on the grass surrounding the slab and initially clings to the concrete, too. But as the minutes pass and the snow begins melting from only its surface, the slab reveals its secret: Like razors, stoves and guitars before it, this concrete has gone electric.

X-ray Vision? Laser-derived X-ray Method Finds Hidden Nuclear Materials
Lincoln, Neb., Dec. 21, 2015 -- Physicists at the Diocles Extreme Light Laboratory at the University of Nebraska-Lincoln have demonstrated that their unconventional laser-based X-ray machine could provide a new defense against nuclear terrorism. In proof-of-principle experiments, the UNL scientists used the laser-driven X-ray source to produce an image of a uranium disk no bigger than a stack of three nickels and hidden between 3-inch steel panels.

Children Who Take ADHD Medicines Have Trouble Sleeping, New Study Shows
Lincoln, Neb., Nov. 23, 2015 -- Stimulant medications for attention-deficit/hyperactivity disorder (ADHD) cause sleep problems among the children who take them, a new study from the University of Nebraska-Lincoln concludes. The study addresses decades of conflicting opinions and evidence about the medications' effect on sleep.
