Art and music for the birds

... of bird listen to and replicate human song. “My interest with the piece was to get us to think about the impact we have on the other species around us,” she adds. The bird listening stations are part of the exhibition “Inside/Outside: Habitat” on view at the Abington Arts Center’s Sculpture Park in Jenki...

Soils offer new hope as carbon sink

...uels. "So it is not surprising there is so much interest in a technology to create clean energy that also locks up carbon in the soil for the long term and lifts agricultural production," he said. The trials at Wollongbar have focused on the benefits of agrichar to agricultural productivity. "When ap...

Envisat captures first image of Sargassum from space

...d influence on climate, making them major areas of interest for climate modellers. The discovery was made using the MERIS maximum chlorophyll index (MCI) which provides an assessment of the amount of chlorophyll in vegetation to produce detailed images of chlorophyll per unit area. MERIS is uniquely suit...

Undergraduate research shows leaderless honeybee organizing

... of the colony’s workers. Though it is of great interest to researchers studying social behavior, a great mystery still remains regarding how bee societies effectively direct and coordinate complex operations without a central controlling intelligence. Pierce’s finding is part of an ongoing research effort...

Understanding why C. difficile causes disease -- it's hungry

...he toxins out. The last two genes are of greatest interest to Sonenshein and his colleague, Bruno Dupuy from the Institut Pasteur. One codes for a protein, known as R, that is necessary for the expression of the first three genes and the other codes for a protein called C that prevents R from acting. A ...

Amphibians in losing race with environmental change

...note in their report. Amphibians are of particular interest because their physiology and complex life cycle often exposes them to a wider range of environmental changes than other species must face ?they have permeable skin, live on both land and water, their eggs have no shells. In the face of these chall...

Survival of the rarest: Fruit flies shed light on the evolution of behavior

...s of the foraging gene. This gene is of particular interest because it is also found in many organisms, including humans. The new study appears in the May 10 issue of the journal Nature. "There's considerable genetic variation in nature and we haven't been able to explain why it persists, since natural sel...

DOE JGI sets 'gold standard' for metagenomic data analysis

...ts, compare their dataset from their metagenome of interest against the simulated metagenome, and receive guidance as to which are the optimal tools for analysis. "Having such a tool at hand for the first time now, the community can not only compare the methods, but can also ask the question, why is this m...

Spud origin controversy solved

...y adapted. “The results of these studies are of interest not only to evolutionists but also for breeders. Years of effort were made to artificially recreate the European potato from Andean landraces yet it may have originated from Chile,?said Spooner. “If the true origin of the European potato was from Chi...

Herpes infection may be symbiotic, help beat back some bacteria

...nfections, Virgin made a discovery that piqued his interest in the possibility that latent infections might confer unrecognized benefits. "We found evidence that the mouse immune system controls latent herpes infections in part by increasing production of a protein hormone called interferon gamma," Virgin ...

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

...ed their attention to the oceans in the 1970s, and interest grew in manganese nodules that exist on the surface of the ocean floor. However, high projected costs and the regulatory restrictions on deep sea mining in international waters through the United Nations Convention on the Law of the Sea (UNCLOS) have...

No magic tomato? Study breaks link between lycopene and prostate cancer prevention

...st prostate cancer, spurring commercial and public interest in the antioxidant. Antioxidants protect against free radicals, highly reactive atoms and molecules that can damage DNA and other important molecules in the cell. Since free radical damage increases with age, there has been a long-held suspicion in t...

Uniform language for describing genes of pathogenic and beneficial microbes

...e Ontology (PAMGO) project, a recently-established interest group of the worldwide Gene Ontology Consortium. The GO Consortium has been working since 2000 to develop a common language of terms that can be used to describe how individual genes function in diverse organisms. The PAMGO project is supported by t...

Deconstructing brain wiring, one neuron at a time

...ld be used to map the connections of cell types of interest or even of single cells. The solution came from a conversation between Callaway and John Young, Ph.D., a Professor in the Infectious Disease Laboratory, and co-author of the study. When Callaway described the problem, Young immediately suggested the ...

Researchers wake up viruses inside tumors to image and then destroy cancers

...ps the virus begin to reproduce. This kinase is of interest because researchers know its "sister" kinase, the one produced by the herpes simplex virus, can be imaged by an injected radiolabeled chemical (FIAU), which can then be imaged using a gamma camera. "To perform molecular-genetic imaging, we have a...

Sandia researchers take new approach to studying how cells respond to pathogens

...s on rare cell types." Proteins in the cells of interest are tagged with fluorescent molecules, essentially colored dyes. The dyes range from green to red and give researchers the opportunity to track proteins and see, for example, the dynamic cellular production of proteins or protein-binding processes in...

Gene found for rare disorder may reveal new pathway in mental retardation

... In the current study, mutations in two genes of interest cause mental retardation, but with less pronounced facial features and none of the limb defects, such as missing hands or fingers, that are hallmarks of classical cases of CdLS. The genes play important roles in early development, and when mutated, c...

Mine runoff continues to provide clues to microbial diversification

...with a limited number of members. Of particular interest to DOE is how this effort relates to its Genomes to Life program, which is focused on identifying and characterizing the molecular machines of life. This study helps extend the initial studies of microbial isolates growth in carefully controlled labo...

Discovery could lead to better control of hemorrhagic fever viruses

... South America, the viruses are of U.S. government interest because of their potential as bioterrorism agents. All four are classified as NIAID Category A Priority Pathogens and must be handled in Biosafety Level 4 containment facilities. The researchers, led by Hyeryun Choe, PhD, of Children's Hospital Bo...

Loss of a universal tRNA feature reported

...n aminoacyl-tRNA synthetase. It will be of special interest to examine if the loss of this tRNA feature has resulted from the presence of an RNase P enzyme that is no longer capable of catalyzing abnormal cleavage at the -1 position in the tRNAHis precursor. It will also be revealing to see how different amin...
