New Find From Joint BioEnergy Institute Could Help Reduce Biofuel Production Costs
In the search for technology by which economically competitive biofuels can be produced from cellulosic biomass, the combination of sugar-fermenting microbes and ionic liquid solvents looks to be a winner save for one major problem: the ionic liquids used to make cellulosic biomass more digestible for microbes can also be toxic to them. A solution to this conundrum, however, may be in the offing.(more…)
Marine science majors conduct field research with horseshoe crab census
Wearing sneakers and rain boots, University of Delaware freshmen got their feet wet as marine biologists recently while counting horseshoe crabs along the Delaware Bay. The students participated in a monitoring effort to gain firsthand experience in field research with their fellow marine science majors.
“Where else can you go on a Saturday night to count horseshoe crabs?” freshman Will Goldman said. (more…)
Thanks to the generosity of three professional meteorite hunters, the UA Lunar and Planetary Laboratory will own three samples of a rare kind of meteorite leftover from the earliest beginnings of the solar system.
To the untrained eye, the black, smooth-edged lump that is sitting under a glass cover looks similar to a piece of charcoal. But to scientists Dante Lauretta and Ed Beshore from the University of Arizona Lunar and Planetary Laboratory, it is one of the most intriguing stones they have ever seen.
“This meteorite is the oldest rock you’ll ever find on Earth. In fact, it formed 50 to 60 million years before the Earth even existed,” said Lauretta, who is a professor of planetary science and principal investigator of NASA’s OSIRIS-REx mission, which will send a spacecraft to return a sample from an asteroid in 2023.

Discovery ultimately could lead to better climate understanding and prediction
COLLEGE PARK, Md. Is Earth really a sort of giant living organism as the Gaia hypothesis predicts? A new discovery made at the University of Maryland may provide a key to answering this question. This key of sulfur could allow scientists to unlock heretofore hidden interactions between ocean organisms, atmosphere, and land — interactions that might provide evidence supporting this famous theory.(more…)
Robert Abramovitch of MSU’s Department of Microbiology and Molecular Genetics is using a synthetic biosensor that glows green in response to conditions that mimic human tuberculosis infection. He will screen for compounds that target chronic TB infection and may help shorten therapy or treat multidrug-resistant TB, which does not respond well to existing antibiotics. (more…)
For two molecules on blind date, new method predicts potential for attraction or repulsion
Krzysztof Szalewicz, professor of physics and astronomy at the University of Delaware, and Rafal Podeszwa of the University of Silesia Institute of Chemistry in Poland have developed and validated a more accurate method for predicting the interaction energy of large molecules, such as biomolecules used to develop new drugs.
The research is reported as a communication in the April 27 issue of the Journal of Chemical Physics, which is the most highly cited journal in atomic, molecular and chemical physics according to Thomson Reuters. The journal is published by the American Institute of Physics. Despite appearing at the end of April, the paper was on the list of the 20 most-read articles in JCP for that month. (more…)
ANN ARBOR, Mich.— A hidden facet of a math problem that goes back to timeworn Sanskrit manuscripts has just been exposed by nanotechnology researchers at the University of Michigan and the University of Connecticut.
It turns out we’ve been missing a version of the famous “packing problem,” and its new guise could have implications for cancer treatment, secure wireless networks, microelectronics and demolitions, the researchers say.
Called the “filling problem,” it seeks the best way to cover the inside of an object with a particular shape, such as filling a triangle with discs of varying sizes. Unlike the traditional packing problem, the discs can overlap. It also differs from the “covering problem” because the discs can’t extend beyond the triangle’s boundaries. (more…)
Team members of NASA’s Mars Science Laboratory mission took a test rover to Dumont Dunes in California’s Mojave Desert this week to improve knowledge of the best way to operate a similar rover, Curiosity, currently flying to Mars for an August landing.
The test rover that they put through paces on various sandy slopes has a full-scale version of Curiosity’s mobility system, but it is otherwise stripped down so that it weighs about the same on Earth as Curiosity will weigh in the lesser gravity of Mars. (more…)
