Not-for-profit publishers call NIH public access rule a missed opportunity

...id the confusion that would result from publishing two different versions of the same article--an unedited version on PubMed Central and the final version in the journal. "The society publishers' proposal would avoid problems that are bound to occur if there are multiple versions of the same article," s...

Researchers devise way to mass-produce embryonic stem cells

... in a flask and those grown in the bioreactor ?for two key proteins. The presence of these proteins indicates that a stem cell has not differentiated. In the bioreactor experiment, 94 percent of the stem cells tested positive for these proteins, compared to about 85 percent of the cells grown in the flas...

HIV vaccine trial breaks ground for future research

Flocking together: Study shows how animal groups find their way

...ound that group coordination arises naturally from two basic instincts: the need to stay in a group; and ...earchers extended their experiments by introducing two subgroups with differing preferences about which direction to move. The overall group consistently c...

PGA on a tour under the skin

...nthracis, but several differences exist in how the two pathogens use PGA to their advantage. PGA is currently used as an antigen for vaccine production against Anthrax This paper presents PGA as a promising target for drug development aimed at combating these hospital-acquired infections and other illne...

Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert

...e able to detect lichens and bacterial colonies in two areas: a coastal region with a more humid climate and an interior, very arid region less hospitable to life. "We saw very clear signals from chlorophyll, DNA and protein. And we were able to visually identify biological materials from a standard ima...

Reducing malarial transmission in Africa

...rial of 497 children in Uganda treated with one of two leading combination therapies. One regimen was an artemisinin-based combination consisting of artemether and lumefantrine (co-artemether, trade names CoArtem and Riamet). The other was a combination of CQ and SP - currently under consideration in sev...

Advances in the characterisation of the oyster mushroom genes

...runks of trees where the lignin and cellulose ?the two principal components of wood - are being broken down. Degradation of lignin has been studied over the years by a number of research teams that have characterised the genes involved. But nobody, to date, has tackled the degradation of cellulose from a...

Transgenic plants remove more selenium from polluted soil than wild plants, new tests show

Researchers discover chemical compounds that affect plant growth

...h hormone involved in gravitropic responses, while two of the four did not work through known auxin pathways. One of the chemicals resembled pyocyanin a product of bacterial metabolism thought to target yeast cell membranes. With chemical genomics, the team could identify valuable genetic characteristics...

Light therapy may combat fungal infections, new evidence suggests

...of C. neoformans. The Duke team has now identified two genes responsible for that light response. Loss of the same genes also reduces fungal virulence in mice, they reported. Earlier studies had linked the genes to light-sensing in another distantly related fungal lineage, an indication that the fungal ...

Computational Method Speeds Mapping of Cell Signaling Networks

...unknown T-cell signaling interaction that connects two pathways. Prediction is the great strength of Bayesian network analysis--particularly in the post-genomic age when researchers are generating vast amounts of data. The statistical approach requires no prior knowledge of signaling pathways to uncover...

Researchers find new genes necessary to make embryo

The C. elegans study suggests specific cellular roles for these genes, thus providing important clues to how these genes work in humans. The new data also asked allowed the researchers to have a first genome-wide...
