A regulatory network analysis of phenotypic plasticity in yeast

...ty' refers to the ability of genetically identical organisms to alter their phenotype in response to an environmental change. For example, genetically identical plants grown in sun versus shade will soon look very different from one another. It turns out that some species are more plastic than others. Until no...

VUMC researchers find drug-resistant bacteria MRSA a growing threat

... for well child visits and they have the resistant organisms in their noses." Creech says the next mystery to be solved is why MRSA is increasing in healthy people. "This study tells us there are a lot of children walking around with MRSA who are healthy, but we are also seeing this germ cause infections. W...

Diabetes, hypertension and many cancers arise when these simple, nearly ubiquitous molecules bind incorrectly or not all. Mapping their location on proteins should allow researchers to block aberrant bin...

American Society for Microbiology to host 105th General Meeting in Atlanta

...obiological sciences. Microbiologists study living organisms and infectious agents, and their work is critical to health, agriculture, the environment and biotechnology. Many accomplishments in the microbiological sciences have significantly affected our lives, such as the development of treatments for infect...

Plants defy Mendel's inheritance laws, may prompt textbook changes

...bits of DNA that help identify and locate genes in organisms - to determine whether a plant carried normal or mutant copies of the genes. "It seems that these hothead-containing plants keep a cryptic copy of everything that was in the previous generation, even though it doesn't show up in the DNA, it's not in ...

Scientists identify genetic pathways essential to RNA interference

...abidopsis thaliana, both of which are common model organisms for biological research. The process interrupts the usual transfer of instructions from double-stranded DNA, through single-stranded messenger RNA and finally into proteins. Short, double-stranded pieces of RNA bind to the complementary messenger R...

Same mutation aided evolution in many fish species, Stanford study finds

...f evolution has other tricks up its sleeve to push organisms towards an optimal form for their environment. Other Stanford researchers who participated in the study include graduate students Pamela Colosimo, PhD, first author on the study, and Kim Hosemann; technician Sarita Balabhadra; undergraduate Guadalupe...

Researchers identify cause of 'early bird' sleep disorder

...een in humans with FASPS. So, studies of all three organisms -- flies, mice and humans -- "will help us understand the similarities and differences" in how the gene works in different settings, in different genetic backgrounds, he said. Experiments can be done in mice and flies, with results applying to humans...

The transparent organism: EMBLEM and Carl Zeiss give labs a unique look at life

...-dimensional films of the inner workings of living organisms at a much higher level of detail than ever before. One innovation of SPIM is the illumination of a sample from the side rather than along the traditional view of the microscope lens. This eliminates a problem that has plagued three-dimensional micros...

Natural tumor suppressor in body discovered by UCSD medical researchers

...n a wide variety of chemical signaling proteins in organisms ranging from yeast to humans. Once they found PHLPP, which they discovered was expressed throughout the body, the scientists used biochemical and cellular studies in human and other mammalian tissue to determine that PHLPP levels are markedly reduc...

In a paper titled "The Impact of Insecticides and Herbicides on the Biodiversity and Productivity of Aquatic Communities," published in the journal Ecological ...

New miniaturised chip dramatically reduces time taken for DNA analysis

...NA sensors include: detecting genetically modified organisms in food, either in basic ingredients or in prepared food; identifying people, either to establish blood relations or to find criminal evidence; and testing the toxicity of different drugs to establish what damage they may cause to the DNA molecule of...

"If there is not sufficient light, the spread of the phage might be decreased, which could undermine the efficiency of phage treatment." Ying Jia hopes that the research will lead to a better understanding of the relationship between ...

For sardine and anchovy, El Nio events do not always have the same effects

Satellite images give a better picture of sediment transport

...y particles can come from the activities of marine organisms (biogenic origin). These muds of marine origin, more compact, are more difficult to put into suspension. Accurate indications of the sedimentary particles' biogenic or terrigenous nature should therefore lead to improve further the precision of predi...

An (ecological) origin of species for tropical reef fish

...ay. An ecological speciation model for coral reef organisms may spur the development of a more synthetic treatment of speciation on land and sea. Coral reefs, like tropical forests, express an extreme of life's capacity for variation. Yet high biodiversity in tropical seas foil evolutionists' attempts to expl...
