Potent possibilities for parasite attack

...cked up another surprising finding: the team could assign a function to only one-third of the 200 genes restricted to one or two of the species. "The genome sequences have given us a short-cut to a small number of largely novel genes," explained Dr Chris Peacock, first author on the report. "Given their...

Darwin's famous finches and Venter's marine microbes

...raditional computer. The Salk scientists could assign over half of all GOS sequences to known protein families, and discovered that certain protein profiles are more popular in the ocean or on land. For example, gram-positive bacteria are best known for their hardy spores, but this ability has been enti...

UBC researchers reveal dwarf aquatic plants' hidden ancestry

...upled with a critical re-examination of anatomy to assign these plants to their proper place in the plant evolutionary family tree." Graham and his PhD students Hardeep Rai and Jeffery Saarela, who is now a research scientist at the Canadian Museum of Nature, show that Hydatellaceae are actually closely ...

New study aims to stop sepsis in its tracks

...over a two- to three-year period. It will randomly assign patients to Rivers' protocol or to the existing "usual care" approach, which does not include such aggressive resuscitation. It will then follow all the patients for a full year after their recovery to detect any long-term differences in health and m...

New path from estrogen to survival in breast cancer cells described

...24 issue of the journal, Nature Cell Biology, they assign roles to a number of genes and proteins thought to play a part in breast cancer cell survival, and in the process, have identified potential molecular drug targets. "It's a very complex story, but we have been able to bring together a number of bas...

Surprising symbiosis: Glassy-winged sharpshooter eats with friends

...ll. To really understand the system, you've got to assign the different bits of DNA to organisms. This study shows why." For this particular insect-bacteria trio, genome-based reconstructions of metabolic activity suggest that the two resident bacteria are close neighbors, residing next door within host ti...

First-ever genomic test predicts which lung cancer patients need chemotherapy to live

...thor of the study being reported. Physicians now assign each patient to a clinical "stage" based on the size of the patient's tumor, whether it has invaded lymph nodes and whether it has spread to other organs. They use this staging method to prescribe the best treatment options. But staging parameters ar...

A catalogue of proteins

... Previous analyses had shown that certain proteins assign themselves clearly to particular cell organelles. When the scientists took the protein complex apart, these proteins were used as markers. Proteins which appear together with these marker-proteins could now also be assigned their proper place in the ...

Stanford/Packard scientist's data-mining technique strikes genetic gold

...ed to write software now that will help scientists assign the proper concepts to each experiment." Microarray experiments allow researchers to compare the expression patterns of tens of thousands of individual genes over time in diseased and healthy cells, or in many other experimental conditions. Each exp...

Attention shoppers: Researchers find neurons that encode the value of different goods

...ified neurons that encode the values that subjects assign to different items. The activity of these neurons ...fferent foods, we combine all these attributes--we assign a value to each available item," says Camillo Padoa-Schioppa, PhD, HMS research fellow in neurobiolo...

Warbling whales speak a language all their own

...to break down the elements of the whale's song and assign an abstract symbol to each of those elements. Suzuki wanted to see if he could design a computer program that enabled scientists to classify the structure of the whales' songs. He used the program to analyze structural characteristics of the humpb...

Technique offers new view of dynamic biological landscape

...i array profiles (E-MAP), has already been used to assign new functions to known genes, to uncover the roles of previously uncharacterized proteins, and to define how biochemical pathways and proteins interact with one another. E-MAP will enable new understanding of how genes and proteins function in the ...

Flies on speed offer insight into the roles of dopamine in sleep and arousal

...modulation of neuronal activity and the ability to assign proper saliency (or relevance) to sensory stimuli. ...

MicroRNAs play a big part in gene regulation - and evolution

...unctions of targets, the authors could furthermore assign a biological function to 70% of all microRNAs. "For the first time [this study] compares gene regulation of microRNAs between insects and vertebrates and thus allows insights into the importance and function of microRNAs across huge evolutionary time...

Fleshing out the genome

...e genes, or 48 percent, but they could confidently assign exact biochemical functions for only 16 proteins, or 3 percent. Finally, they introduced a seven-category system for annotating genomic proteins, ranked according to a functional assignment's precision and confidence. Kolker said that "a big part of...
