One species, many genomes

...nged or are lost relative to the reference genome, direct sequencing of the genome of wild strains will allow the detection of new genes. The plan is to decipher the genomes of at least 1001 Arabidopsis varieties. A new instrument, with which the entire genome of a plant can be read in just a few days, is a...

Researchers discover inherited mutation for leukemia

...rtance of the gene in the pathogenesis of CLL, and direct us to target this gene with therapies that might re-activate it." The findings also provide evidence that some genes might contribute to cancer even when they are not silenced entirely. "This inherited change is remarkably subtle," says co-pr...

Undergraduate research shows leaderless honeybee organizing

...ll remains regarding how bee societies effectively direct and coordinate complex operations without a central controlling intelligence. Pierce’s finding is part of an ongoing research effort in Schneider’s lab aimed at understanding the mechanisms of leaderless societal management – in particular, the impor...

Nurtured chimps rake it in

... effects on their cognitive development, and offer direct comparisons with early experience, issues of attachment, and preschool education for human infants and children,” The authors conclude that the differences in performance between the three groups are directly attributable to the significant effect...

Plastic that grows on trees

...glucose is the initial stock. In fact, attempts at direct glucose conversion created so many impurities that it was simpler to start with the fructose, less common in nature than glucose. Zhang and his team, working with a high-throughput reactor capable of testing 96 metal halide catalysts at various te...

Potato wart eyed as risk to potato production

...to plant health or to plant products. Although direct losses from potato wart may be insignificant when first detected, indirect economic losses resulting from zero-tolerance regulations for potato wart can be devastating to growers. Indirect economic losses become especially evident in potato productio...

CU study reveals why starling females cheat

...opulation mate with extra-pair males and gain both direct (like additional helpers) and indirect benefits (like better genes for the offspring), but that they do so in different contexts," said Dustin Rubenstein, a former Cornell graduate student in neurobiology and behavior and now a research associate at ...

Gene therapy study shows safety and statistically significant improvement in Parkinson's disease

...al for Parkinson’s disease and the first report of direct gene transfer into a patient’s own brain cells for any adult neurodegenerative disease. The open label Phase 1 study, conducted in 12 patients with advanced Parkinson’s disease demonstrated both a lack of adverse events related to the gene therapy ...

Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin

...duced by the embryonic mouse pancreas were used to direct adult stem cells to begin developing, or "differentiating," into islet-like cells. As they grew these adult stem cells in the laboratory, the researchers conducted other tests in which the cells to be engineered showed evidence of a characteristi...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...ilor-made genes into cells that can, for instance, direct cells to build more of a needed protein. To deliver the genes into cells, researchers use harmless viruses called vectors, which have evolved to invade human cells and insert their DNA. In designing the new therapy, Kyrkanides’ team chose to work fir...

Eavesdropping comes naturally to young song sparrows

Protein enables discovery of quantum effect in photosynthesis

... Good vibrations "We have obtained the first direct evidence that remarkably long-lived wavelike electronic quantum coherence plays an important part in energy transfer processes during photosynthesis," said Fleming, the principal investigator for the study. "This wavelike characteristic can explain t...

Amphibians in losing race with environmental change

...mphibians lay their eggs in shallow, open water in direct sunlight to provide a more oxygenated environment, increase growth rate of larvae and reduce predation. But the increased levels of UV-B radiation in today's sunlight, due to erosion of the Earth's ozone layer, is causing mutations, impaired immune s...

Corals -- More complex than you?

...r understand coral disease. There may also be a direct payback, in the sense that, by exploring the ancestral immune genetic repertoire of corals and how it functions in a simple animal, we will gain new insights which will help in the battle against human disease, he adds. The richness of the coral g...

8 plants from South Africa may hold potential for treating high blood pressure

...colic and restlessness in young children. The most direct discovery is the 1993 finding that large doses of popular garlic preparations significantly decreased the diastolic blood pressure in human patients 5-14 hours after the dose with no significant side effects. In addition, wild and cultivated garlic p...

Dr Manning added: "Laser scanning allowed the rapid, high resolution, 3D digital mapping of an otherwise inaccessible site. The computer-generated trackways we have created preserve imp...
