University of Delaware researchers have discovered a cheap and efficient catalyst for converting water to hydrogen fuel (known as hydrogen evolution), a vital step in making hydrogen a viable and sustainable energy source.

“The rising concerns about carbon dioxide emissions have led to a growing realization that it is not possible to sustain the world’s current development without a substitution of clean and renewable energy,” writes Feng Jiao, assistant professor of chemical and biomolecular engineering and a co-author on the paper published in the current issue of Nature Communications. “Hydrogen is a potential clean fuel for our society.” (more…)

Pesticide Accumulation in Sierra Nevada Frogs

SACRAMENTO, Calif. — A study on frogs in remote Sierra Nevada mountain habitats including Yosemite National Park and Giant Sequoia National Monument, detected concentrations of pesticides in frog tissue that potentially came from California’s Central Valley sources.

“Our results show that current-use pesticides, particularly fungicides, are accumulating in the bodies of Pacific chorus frogs in the Sierra Nevada,” says Kelly Smalling, a research hydrologist with the U.S. Geological Survey and lead author of the study. “This is the first time we’ve detected many of these compounds, including fungicides, in the Sierra Nevada. The data generated by this study support past research on the potential of pesticides to be transported by wind or rain from the Central Valley to the Sierras.” (more…)

Lariats: How RNA Splicing Decisions are Made

Lariats are discarded byproducts of RNA splicing, the process by which genetic instructions for making proteins are assembled. A new study has found hundreds more lariats than ever before, yielding new information about how splicing occurs and how it can lead to disease.

PROVIDENCE, R.I. [Brown University] — Tiny, transient loops of genetic material, detected and studied by the hundreds for the first time at Brown University, are providing new insights into how the body transcribes DNA and splices (or missplices) those transcripts into the instructions needed for making proteins.

The lasso-shaped genetic snippets — they are called lariats — that the Brown team reports studying in the June 17 edition of Nature Structural & Molecular Biology are byproducts of gene transcription. Until now scientists had found fewer than 100 lariats, mostly by poring over very small selections of introns, which are sections of genetic code that do not directly code for proteins, but contain important signals that direct the way protein-coding regions are assembled. In the new study, Brown biologists report that they found more than 800 lariats in a publicly available set of billions of RNA reads derived from human tissues. (more…)
