As a professor of astronomy and physics, Priyamvada Natarajan doesn’t balk at taking risks. She has modeled the upper limits of “monster” black holes and analyzed the consistency of dark matter. As a theorist, she notes, intellectual risk is par for the course.(more…)
UCLA researchers are now able to peer deep within the world’s tiniest structures to create three-dimensional images of individual atoms and their positions. Their research, published March 22 in the journal Nature, presents a new method for directly measuring the atomic structure of nanomaterials.
“This is the first experiment where we can directly see local structures in three dimensions at atomic-scale resolution — that’s never been done before,” said Jianwei (John) Miao, a professor of physics and astronomy and a researcher with the California NanoSystems Institute (CNSI) at UCLA. (more…)
A University of Delaware oceanographer has stumbled upon an unusual aid for studying local waterways: radioactive iodine. Trace amounts of the contaminant, which is used in medical treatments, are entering waterways via wastewater treatment systems and providing a new way to track where and how substances travel through rivers to the ocean.(more…)
*Nearly Half of UK Smartphone Users Access News At Least Once Each Month*
LONDON, UK, 22 March 2012 – comScore, Inc., a leader in measuring the digital world, today released an overview of mobile news access across the five leading European markets (France, Germany, Italy, Spain and the United Kingdom) using the comScore MobiLens service. The study showed that nearly 37 percent of smartphone users in EU5 reported accessing news sites via an app or browser in January 2012, showing an increase of 74 percent over the past year. For EU5 smartphone users who accessed news sites on a near-daily basis, the growth rate was even stronger at 82 percent. The UK showed the highest penetration with nearly half (46.8 percent) of smartphone users reporting having accessed news sites at least once in the past month. (more…)
HONOLULU – A species of lizard is now extinct from the Hawaiian Islands, making it the latest native vertebrate species to become extirpated from this tropical archipelago.
The copper striped blue-tailed skink (Emoia impar) — a sleek lizard with smooth, polished scales and a long, sky-blue tail — was last confirmed in the Na’Pali coast of Kauai in the 1960s. But repeated field surveys on Kauai, Oahu, Maui and Hawai’i islands from 1988 to 2008 have yielded no sightings or specimens. (more…)
*Berkeley Lab Researchers Show the Way Forward for Improving Organic and Molecular Electronic Devices*
Future prospects for superior new organic electronic devices are brighter now thanks to a new study by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). Working at the Lab’s Molecular Foundry, a DOE nanoscience center, the team has provided the first experimental determination of the pathways by which electrical charge is transported from molecule-to-molecule in an organic thin film. Their results also show how such organic films can be chemically modified to improve conductance.
“We have shown that when the molecules in organic thin films are aligned in particular directions, there is much better conductance,” says Miquel Salmeron, a leading authority on nanoscale surface imaging who directs Berkeley Lab’s Materials Sciences Division and who led this study. “Chemists already know how to fabricate organic thin films in a way that can achieve such an alignment, which means they should be able to use the information provided by our methodology to determine the molecular alignment and its role on charge transport across and along the molecules. This will help improve the performances of future organic electronic devices.” (more…)
A multi-year report says the UA is a driver in the state’s economic development, but more coordination is needed among schools, business and the Legislature.
The University of Arizona and the state’s other colleges and universities have what it takes to produce the expertise needed to improve Arizona’s economy, says an international agency that has been monitoring the region for several years. (more…)
UD study assesses ocean use off Delaware, Maryland and New Jersey coasts
The Center for Carbon-Free Power Integration (CCPI) at the University of Delaware has issued a new report about ocean use off the coast of Delaware and parts of Maryland and New Jersey. The study addresses viable places to locate offshore wind farms, taking into account biological, ecological and other considerations. The report includes feedback from interested groups who attended a November 2011 workshop, as well as input from experts.
“This report demonstrates that the ocean is already active with ecological and human activity,” lead-author Alison Bates said. “It shows what government regulators ought to consider in planning for offshore wind development and the beginning of a way forward for offshore wind developers and existing users to accommodate one another.” (more…)
