W.M. Keck Foundation funds study of friendly microbes

...velop new approaches for isolating, sequencing and analyzing the genomes of "friendly" bacteria that inhabit the intestine and identifying the natural metabolic products that they synthesize in their native gut habitats. The W.M. Keck Foundation, established in 1954 by the late W.M. Keck, founder of the Super...

Neuronal 'traffic jam' marks early Alzheimer's disease

...roaches, said Goldstein. The researchers are also analyzing more brain tissue samples from humans with Alzheimer's disease, to confirm their findings of the early transport defects and their effects on neuronal death. ...

The secret lives of whales

...oned that by taking biopsy samples from whales and analyzing their contaminant loads, he could map levels of pollutants in different ocean. “The oceans act as a conveyer belt carrying contaminants across the globe and depositing them in the fats of seafood,?says Payne. Now in the final year of a five-year glob...

Scientists discover unique microbe in California's largest lake

... scientistsstudied the DNA of the new organism. By analyzing sequence data for thesmall subunit ribosomal RNA gene, which encodes part of the cell'sprotein synthesis machinery, they demonstrated that chlorophylld-producing blue-green algae (more technically known as cyanobacteria)have acquired a piece of DNA f...

MSI releases 'moleculizer' - a new approach to simulation of intracellular biochemical networks

...ry molecularbiology research, aiding scientists in analyzing data and in testinghypotheses with simulated outcomes before testing them experimentally.The predictive capabilities of computer simulations can also aidbiologists in viewing cellular activity over a period of time, bytaking advantage of the power of...

Scientists document complex genomic events leading to the birth of new genes

...RanBP2-like, GRIP domain-containing proteins). By analyzing the gene order around the RanBP2 and GCC2 genes, Bork's team was able to reconstruct the genomic rearrangements leading to the formation of the ancestral RGP locus. These events included a combination of duplication, inversion, partial deletion, and ...

PANTHER Protein Classification System Database 5.0

The PANTHER system database ispublicly available without restriction athttp://panther.appliedbiosystems.com.Today’s announcement coincides with the publicatio...

New RNA polymerase discovered in plants

... noticed the evidence for a fourth polymerase when analyzing gene sequences after Arabidopsis thaliana , the "laboratory rat" of the plant world, was sequenced in 2001. It originally looked to him like an alternative form of either Polymerase I (Pol I), which makes the largest of the ribosomal RNAs, Pol II whi...

RNA project to create language for scientists worldwide

...ion technology merge. Methods he has developed for analyzing and classifying RNA structures have been adopted internationally to advance RNA structure prediction and simulation and RNA sequence analysis. His work is supported by the National Institutes for Health and the American Chemical Society. Leontis des...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

...pens several avenues of new research. For example, analyzing the sequence and location of these CNEs may help point the way to other non-coding elements that remain undiscovered. It is also likely that mutations in these critical sequences cause human diseases. Studying how such mutations drive development ast...

World's largest rainforest drying experiment completes first phase

Scientists with The Woods Hole Research Center are analyzing the surprising results of the first phase of a drydown experiment occurring in the Amazonian rainforest. From January 2000 to July 2004, rainfall was excluded from a one-hectare (2.2 acre) plot in the middle of the Tapajós National Forest, in Brazil...

Great White shark evolution debate involves WSU Lake Campus geology professor

...mpaglio. "However, our research, which is based on analyzing fossils of several hundred shark teeth, shows that the Great White shares more similarities with the mako shark." He added that because sharks regularly replace their teeth, it is relatively easy to obtain tooth samples through fossil field work alon...

Nanoscale Diagnostic Sets Sights on Alzheimer's

...r-code amplification (BCA) technology, researchers analyzing fluid from around the brain and spinal cord have detected a protein linked in recent studies to Alzheimer's disease. Interesting application Read more about the bio-bar-code technology : - Gold nanoparticles and bio-bar codes bring sensitive DNA ...

Researchers make gains in understanding antibiotic resistance

...ing atomic structure of the proteins is deduced by analyzing the pattern of diffraction of the x-rays. Steitz's group used ribosomal subunits from the primitive archaebacterium Haloarcula marismortui (Hma), which is found in the Dead Sea. They chose Hma ribosomes for their studies because they crystallize wel...

Study: 'homemade' gene expression technology unreliable

Technology for analyzing gene expression must be standardized among laboratories and across platforms around the world to support this age of human genome exploration, an Oregon Health & Science University researcher says. Otherwise, scientists using DNA microarrays, al...

Scientists journey to southern Africa to unravel the secret world of elephant communication

...ssment of the elephants' behavior. Although still analyzing data from the 2004 experiment, O'Connell-Rodwell is able to make a few preliminary observations: "The data I've seen so far suggest that the elephants were responding like I had expected. When the '94 warning call was played back, they tended to clum...

Researchers discover underwater volcano

...Nafanua and assisted researchers in collecting and analyzing data. These students also created and maintained an in-depth web site related to the cruise where they posted reports, maps, photos and videos from submersible dives. Also, the students and scientists aboard the ship participated in the first ever st...

One gene links newborn neurons with those that die in diseases such as Alzheimer's

...ts allowed male finches to sing to a female before analyzing the birds' brain neurons. As predicted, the expression of UCHL1 in replaceable neurons, but not in nonreplaceable ones, increased in birds that were singing. "These findings suggest that rising levels of UCHL1 may be associated with a reduced risk o...

Protein prevents detrimental immune effects of bacterial sepsis

...host. Damazo et al. studied this balancing act by analyzing the effects of the bacterial toxin LPS on normal and annexin 1 knockout mice. Annexin 1 was chosen because it appears to be involved in the resolution phase of the immune response: its expression on white blood cells impairs their ability to bind blo...

Man-made wetland's effectiveness similar to natural marsh

... studied the wetland for two years, collecting and analyzing water samples twice each month. They tested the samples for concentrations of phosphorus, nitrates and several other chemicals. The researchers also gathered data on water flowing into the wetland from rain and snowfall and from ground sources. They...
