Genetics links whale to two different ocean basins

... of inter-oceanic exchange of individuals. Using a method of genetic capture-recapture of genotypes constructed of microsatellite markers, the researchers identified an individual whale sampled in Gabonese waters in 2002 that had been first seen (and sampled) with its mother in Madagascar waters in 2000. Po...

Change in gene may be underlying molecular defect in some colorectal cancers

... 50% to 94% of colorectal tumors, depending on the method of detection, and normal-appearing colon mucosa up to 10 cm away from the tumor had detectable MGMT methylation. In addition, the authors detected MGMT methylation in the normal colon mucosa of several subjects who did not have cancer. "Because a lo...

Hanging baskets of sex and death help fruit growers

...is is wasteful both of time and resources. By this method the moth themselves spread the virus in a very targeted way to other moths and prevents loss of populations of other beneficial insects such as the red spider mite which would occur if growers used pesticides. Extended virus life - The virus does no...

After the yeast is gone bacteria continue to develop flavor of sparkling wine

...earcher on the study. The traditional Champenoise method of sparkling wine production requires addition of sucrose and yeast strains to the base wine for a second fermentation in the bottle in which the wine is sold. The secondary fermentation produces carbon dioxide which dissolves in the wine and is perc...

Nanoscale method for investigating living systems

...lectrical and computer engineers has devised a new method for investigating living systems on the molecular .... These artificial portals or pores could enable a method of investigating living systems by means of semiconductor technology that until now could be theoriz...

No small feat: First ever gene therapy success for muscular dystrophy achieved

...e defective in CMD, and applying a newly developed method for "systemic" gene delivery, the Pitt researchers...ry ?a single infusion into the abdominal cavity ?a method the authors only recently described and which they used for the first time in this study to transfer...

New processing method reduces peanut allergenicity

...the allergenicity of peanuts that one fermentation method reduced the detectable level of major allergenic proteins like Ara h1 and Ara h2 by as much as 70 percent without causing any adverse effects on sensory quality of the final product. "It is hoped that careful control of the process conditions may en...

Carnegie Mellon cyLab researchers work to develop new red tide monitoring

...indings to homeland security where we may use this method to track the bioterrorism activities pertaining to the nation's waterways." Cai said his NASA/ESTO-funded research team is developing a spatiotemporal data mining system to track harmful ocean objects from NASA's SeaWiFS satellite images and NOAA's ...

New law for resolution allows unprecedented sharpness in fluorescence microscopy

...t confining the solution itself mechanically. This method may substantially improve the analysis of pharmaceutical active ingredients and protein interactions in cells in future. Original work: [1]Hell, S. W. Strategy for far-field optical imaging and writing without diffraction limit. Phys. Lett. A 326(1...

Enzyme affects hypertension by controlling salt levels in body

...ypertension, abbreviated PHA II, but until now the method by which it affected blood pressure was unclear. By studying animal and human cells in culture, UT Southwestern researchers determined that WNK1 interacts with and activates another enzyme, SGK1, which is well known to lead to the activation of sodiu...

NYU biologists map out early stages of embryo formation

...ic approaches including RNA interference (RNAi), a method for studying the function of genes in vivo, the researchers were able to develop a first-draft diagram for the early embryo at the molecular level, describing how its components fit together both physically and logically. "These results point to a h...

Vaccine targets tumors where they live

...ersity manipulate the local tumor environment as a method for improving systemic anti-tumor immunity. This concept has been suggested in mouse models but had not established in the clinical setting. The data represent the first clinical trial to directly inject a vaccinia virus expressing the B7.1 costimula...

New plant DNA libraries provides massive boost to world's plant researchers

...y "restriction enzymes" to cut up the DNA but this method may preferentially select only certain regions of DNA and exclude other regions from the final plant "library". The techniques used by the Warwick researchers remove this limitation and make the plant's entire DNA available to researchers. The new p...

New tooth enamel dating technique could help identify disaster victims

...etermine a person's age at the time of death. The method could help in the identification of victims of Hurricane Katrina and other large-scale disasters. The new technique, developed by researchers at Lawrence Livermore National Laboratory (LLNL) and the Karolinska Institute in Sweden, determines the amo...

Scavenger cells could be key to treating HIV-related dementia

...he results. Dubbed phylodynamic analysis, this new method links traditional ways of studying the virus to give researchers a more comprehensive understanding, which Salemi says is crucial to analyzing the ever-changing disease. "If we really want to understand what happens to a person infected with this di...

Scientists find a maturity gene in fly

...ds: conventional "knockout" technology and a newer method in which the gene was "silenced." By showing what happened when the gene was disabled, the researchers determined the normal gene has two key functions: * DHR4 determines when metamorphosis should begin, when the fly should begin changing from ...

Elusive salamanders have role in developing new sampling models

...elhimer said. "So for us, our task is to develop a method to make field sampling techniques more accurate and efficient. With that information, we can improve our models, and we should be able to do a better job of predicting the type and location of suitable habitats plus minimize unnecessary and time-cons...
