Quick identification needed to save Florida's citrus industry from devastating disease

... Proper identification and eradication methods are needed to reduce the amount of crop loss caused by this disease, say plant pathologists with The American Phytopathological Society (APS). Citrus greening is a bacterial disease that affects the phloem system of citrus plants causing the infected trees to y...

NASA satellite data provides rapid analysis of Amazon deforestation

...al images. While high resolution imagery is still needed when estimating the total area of deforestation or when identifying small clearings, "the most exciting finding of this study is that it shows MODIS can permit regional analyses of land cover in a matter of days, a substantial reduction in effort in ...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

...esolution models of the ribosome structure will be needed to design targeted drugs, Frank said. ...

Immune system has evolved to prevent autoimmune disease

...ies the immune system could use to reduce the time needed to create an effective B cell. In addition, these methods also could produce antibodies that are more apt to bind with disease cells. The upshot would be an immune system that responds faster and more effectively against disease."This should help us ...

Techniques available to detect soil that inhibits destructive soybean pest

...e-eating microbes, Westphal said. Further study is needed on how microbial communities function in order to determine conditions that contribute to nematode development. Westphal was able to confirm the nematode supressiveness of soil by using treatments to eliminate soil organisms and other elements that ...

Stolen gene allows insect virus to enter cells

...mined how baculoviruses took the evolutionary leap needed to become the nasty bugs they are today. In the study, reported in the July 1 issue of the Journal of Virology, BTI researchers Gary Blissard and Oliver Lung investigated whether a fruit fly gene, called an f gene, had originally moved from an insec...

Researchers discover key to human embryonic stem-cell potential

... cell growth, they also repress a key set of genes needed for an embryo to develop. This key set of repressed genes produce additional transcription factors that are responsible for activating entire networks of genes necessary for generating many different specialized cells and tissues. Thus, Oct4, Sox2,...

Discovery that bacterium is phosphate gourmet key clue to what makes it most social of bacteria

...dependent signalling pathway to find the phosphate needed for consumption, and so the other two pathways found in M. xanthus simply did something else. In collaboration with Prof Mitchell Singer of the University of California at Davis, Dr Whitworth found that in fact the bacterium was using all three pathw...

Disease association research is the main reason why the group from Calit2 and ICSI opted to identify tag SNPs across the entire NCBI database and make all of them...

Software 'agents' could help unmask reality of disease clusters

...ect individual privacy can destroy the information needed for geographical analyses, making it impossible to address many important public health concerns," said Dr Maged Boulos, from the School for Health at the University of Bath. "Some of the solutions used to preserve confidentiality, such as centralis...

An essential regulator of body weight revealed

... mice whose NPY/AgRP neurons produced the molecule needed to recognize and take up that toxin. Then, by administering diphtheria toxin to these animals, the scientists could destroy NPY/AgRP neurons without causing other harm. Once they'd eliminated those neurons, the scientists monitored precisely how muc...

"Many of these evolutionarily conserved microRNA targets are known to be active in the processes of cell proliferation, development, and cancer," says Farh.
