Most widely used organic pesticide requires help to kill

...cases of human septicemia, so if this mechanism is shared by Bt and toxins produced by human pathogens, the implications could be far greater in medicine than in agriculture," Handelsman says. ...

How many genes does it take to learn? Lessons from sea slugs

...c Kandel, M.D., of Columbia University in New York shared the Nobel Prize in Physiology or Medicine for his work using Aplysia as a model of how memories are formed in the human brain. Despite its simple nervous system - Aplysia has about 10,000 large neurons that can be easily identified, compared with ...

K-Staters design and build a low-cost remote sensing tool for environmental studies

...hinstock, the remote sensing tool will meet a need shared by thousands of environmental scientists worldwide. For just a few thousand dollars, researchers will have a way to collect data for small ecosystem sites at low altitudes and at very slow speeds. Until now, climate research has required costly, pilo...

Biologists find regions of rice domestication

...nge of rice and looked for DNA sequences that were shared by both wild and domesticated types. These two ma...laborators concentrated on finding genetic markers shared by both cultivated and wild rice types that ranged from 800 to 1,300 base pairs. Cultivated rice h...

Joslin discovers signs of residual islet cell function in people with long-term type 1 diabetes

...physiological, clinical, genetic and other factors shared by the Medalists. The study being presented at the ADA meeting is part of the second phase of the Joslin 50-Year Medalist Study that is assessing these factors in 326 patients with more than 50 years of insulin-dependent diabetes. It evaluated a su...

Computational analysis shows that plant hormones often go it alone

...es to a publicly available database, where data is shared by colleagues investigating diverse biological questions. "The data was there but nobody had compared the effects of different growth hormones on gene expression side by side," says Nemhauser. The amount of data analyzed by the Chory group was eno...

Nicotine exposure during development leads to hearing problems

... is mimicking the action of acetylcholine on their shared receptors and increasing responsiveness to sound if those receptors had not been previously damaged. ...

NHGRI announces latest sequencing targets

...i-cellular groups of organisms (fungi and animals) shared a single-celled ancestor. This project targets ten of the earliest branches of animals and fungi along with some of their single-celled relatives providing, for the first time, comprehensive data to fill gaps in our understanding of animal and funga...

How can identical twins be genetically different?

...ion patterns of 11 pairs of monozygotic twins, who shared the same egg and were genetically identical, but only one of them had RA. They found three new genes that were significantly over-expressed in the twin with RA compared to the one without the disease. This is the first report for RA that examines gen...

UF scientists discover evolutionary origin of fins, limbs

...rical pairs of fins on the animal sides, showing a shared developmental mechanism in completely different locations, according to Renata Freitas and GuangJun Zhang, co-authors of the paper and graduate students in UF's zoology department. Extending their genetic analysis to the lamprey - a living relic fr...

Researchers map out networks that determine cell fate

...operty of mixed lineage transcriptional priming is shared amongst different kinds of stem cells, then resolving these mixed-lineage states will invariably involve counteracting repressors." In collaboration with colleague Aaron Dinner, the research team also formulated a mathematical model that depicts the...

Genomatix technology facilitates de novo identification of new renal disease associated genes

...rmatics approaches allow rapid characterization of shared promoter structures which can be used to find novel interacting molecules. Here, these principles are applied to a set of genes linked to the unique functional unit of the glomerular slit diaphragm. An evolutionarily conserved promoter model was gene...

Researchers identify genes in fruitflies that may shed light on human cancer spread

...e difficult to study because their functions are shared by other genes; and some that are well understood for their roles in other cellular functions but without this study would not have been obvious candidate genes in cell migration. The results help these researchers as well as others in the field by p...

Common molecular 'signature' identified in solid tumors

...t in human cancer, had a hunch that there might be shared patterns of miRNA among certain cancers. Under his direction, researchers looked for miRNA activity, or expression, in 540 samples of lung, breast, stomach, prostate, colon and pancreatic tumors and in the normal tissue surrounding them. Using micr...

Study finds 60 new genes controlled by DNA snippet

... function. Miano's screen required that CArG boxes shared by humans and mice be included in his expanded version of the CarGome. CArG boxes identified by the computer screen were then tested to see if they indeed interacted with SRF and changed the behavior of genes as predicted. This approach resulted in ...

Evolution mystery: Spider venom and bacteria share same toxin

...oxins had previously been noted, but this uniquely shared structural bit is best explained by these toxins being more closely related to each other than they are to any other known protein. "That one structural detail--which resembles a plug or cork at the end of a barrel-shaped enzyme--is evidence that t...

Anemone genes reveal versatile building blocks for body plans

...ew findings, scientists are now studying how these shared genes are used by radial and bilateral animals to learn how different body plans are determined and built at the molecular level, and how they arose during evolution. The work is reported in the March 7th issue of Current Biology by David Matus and...

Alzheimer's found to be mostly genetic

... due to non-shared environmental causes. Risk from shared environments, such as childhood settings that were the same for both twins, was statistically negligible. Genetic risk for Alzheimer's was the same for men and women after controlling for age. The study is notable for its careful approach to Alzhe...

Lizard 'third eye' sheds light on evolution of color vision

...parison method used by the parietal eye is not one shared by humans, it does reveal one potential step in the evolution of color vision, the Hopkins researchers say. Human light-reception cells responsible for color vision are called cone cells or photoreceptors, and they contain only one kind of pigment p...

Report finds cruise industry is protecting the precious places it visits

... Business (CELB). From Ship to Shore examines the shared responsibilities among cruise lines, governments, civil society groups and shore operators to manage the growth and expansion of the cruise industry into sensitive ecosystems. The report also profiles leadership examples of how these stakeholders are...
