Living with salt

... environments. The proteins they investigated were isolated from halophilic (salt-loving) microorganisms from the Dead Sea. After determining the 3-D structures for several halophilic proteins, researchers were able to explain how these proteins not only cope with high salinities, but are actually "addicted" ...

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

... sensory characteristics of Cava. The researchers isolated 617 microbial strains from two Cavas, after 9 to 17 months of bottling. No yeasts were isolated after 10 months of bottling. Gram-negative and Gram-positive bacteria were isolated from both wines....

Researchers find molecule that inhibits regrowth of spinal nerve cells

...search fellow, they cultured neurons together with isolated ephrin-B3 and confirmed that the molecule activated the neuron's receptors. They then cultured normal myelin together with the neurons and got the same results. However, when they cultured neurons with myelin from which the ephrin-B3 had been remove...

New tools used to control foodborne hepatitis A outbreaks related to green onions

...k, however, was identical to one or more sequences isolated from northern Mexican residents infected with hepatitis A virus. The researchers concluded that the sources of the green onions served in restaurants in Tennessee and Georgia were three farms in northern Mexico. Dr. Amon and colleagues credited the...

Solution to 'legionella'

...). A wide range of trials were carried out in this isolated and secure system in order to determine the efficacy thereof. Regarding the technology developed, it consists of a system based on low-intensity, high-frequency ultrasounds which, together with the introduction of micro-bubbles of air, produce an ef...

Learning how SARS spikes its quarry

...nings of information needed -- if a new virus were isolated -- to make predictive guesses about infectivity, so that we can better give advance warning." He also noted that laboratory studies indicate that the fragment of the spike protein they used could provide the basis of a vaccine against SARS, since i...

Birds and bats sow tropical seeds

...'s a way of providing connection between existing, isolated trees, remnants and fragments and large tracts growing along rivers in rain forests," he said. "I think what it will show is that the replanting that almost everybody does in (tropical regions) is an extremely inefficient way to maintain and promote...

Genetic link confirmed between Polynesians and indigenous Taiwanese

...anese aboriginal populations have been genetically isolated from mainland Chinese for 10,000 to 20,000 years, and that Polynesian migration probably originated from people identical to the aboriginal Taiwanese. Further research will be necessary to precisely determine the origins of the aboriginal Taiwanese; ...

Drug resistant avian influenza viruses more common in Southeast Asia than North America

Picky female frogs drive evolution of new species in less than 8,000 years

...nce." The yet-to-be-named species arose after two isolated populations of the green-eyed tree frog reestablis...sand years, this behavior created a reproductively isolated population - essentially a new species - that is unable to mate with either of the original frog pop...

Volunteers sought for avian flu vaccine study

...i Pasteur from an inactivated H5N1 avian flu virus isolated last year. "It's similar to the concept of the regular flu vaccine that people get every year, but it's targeted to this novel type of flu," Edwards said. Because the study is beginning at the start of this year's influenza season, all participants...

Grasshopper love songs give insight into sensory tuning

...rs first played various snippets of white noise to isolated grasshopper auditory nerves and measured the electrophysiological signals reflecting the reactions of the auditory neurons to those sounds. These experiments revealed the distribution of stimuli called the "optimal stimulus ensemble" (OSE) that allow...

Emerald Spectre haunts Ontario's ash forests

A new study shows that while we're winning isolated battles, we could well lose the war to prevent the devastating spread of the emerald ash borer in eastern Canada and the United States. It's a failure that would cost billions of dollars in lost timber and ornamental trees, and dramatically change th...

Studies on human genome variation provide insight into disease

...oning," explains Larionov. "Using this method, we isolated the SPANX region from 200 individuals by recombination in yeast." Based on their results, the authors speculate that predisposition to prostate cancer ?at least in some individuals ?is determined by the specific architecture of the SPANX gene ...

Gene therapy reverses genetic mutation responsible for heart failure in muscular dystrophy

...be the case. "The AAV-8 we used in this study was isolated from monkeys, so we are very hopeful it will be able to deliver the genes before the human immune system produces antibodies to block it. In addition, we used a muscle-specific promoter in the virus, which also should lower the risk of any potential ...
