Ocean climate predicts elk population in Canadian Rockies

...ern North America, but Hebblewhite is a pioneer in working with NPO values. "It's important to figure out what climate change means to us in terms we can understand," he said. "The more we know, the more we can do to produce the outcomes we desire and prevent the ones we don't." In 2002, Hebblewhite won th...

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments

... for this process." PK2 accomplishes this task by working with its corresponding cell receptors, which are part of the G protein-coupled receptor (GPCR) family. GPCRs are proteins found in a cell's membrane and play a critical role in transferring signals from outside of a cell to the molecular machinery wi...

Diabetic nerve therapy shows 'striking' results

...rica. Scientists at The University of Manchester, working with colleagues at American biotech firm Sangamo BioSciences Inc, have discovered a way of stimulating genes that prevent nerve damage caused by the disease. Professor David Tomlinson, who is leading the research in Manchester, says the study has ma...

Researchers find first evidence of venom system in extinct mammal

...just shows you that no matter how long you've been working on something, you can still learn a lot just by uncovering one little piece of information," Fox added. "And we're fortunate that we are able to work where we do; central Alberta is one of the richest areas of the world to uncover the types of fossil...

Scientists reveal how disease bacterium survives inside immune system cell

... emerging infectious disease, and Dr. Borjesson is working to understand how it affects blood cells -- and neutrophils in particular. "Few people know about this pathogen, but it is important because it is transmitted by ticks and causes disease in both animals and humans," Dr. Borjesson says. Neutrophils, ...

Achilles heel of the herpes virus possibly found

...redits the persistence of research team members in working with the genomic library and culture of human and pig cells, especially U-M doctorate graduate Aleida Perez and postdoctoral fellows Qingxue Li and Pilar Perez-Romero. Perez-Romero is first author of one of the two new papers, and a co-author on the ...

Biologists determine genetic blueprint of social amoeba

...ome also allowed Rolf Olsen, a postdoctoral fellow working in Loomis' laboratory, to generate a tree of life and show that amoebozoa, the group to which Dictyostelium belongs, evolved from the common ancestor of eukaryotes (the group of organisms that contain all animals, plants, algae, protozoa, slime mold ...

Newly discovered genetic disease sheds light on body's water balance

...findings about the two patients to the laboratory, working with colleagues to isolate the genetic mutations responsible for their disruption in water balance. They found that each infant has a different mutation in a specific gene, AVPR2, that encodes the V2 receptor (V2R) for vasopressin, a hormone that in...

Self-assembled DNA buckyballs for drug delivery

...g material, constructing geometric shapes and even working mechanical devices. Now Cornell University researchers have made DNA buckyballs -- tiny geodesic spheres that could be used for drug delivery and as containers for chemical reactions. The term "buckyballs" has been used up to now for tiny spherica...

Researchers identify new genes that regulate aging

... lifespan doubles when one gene is prohibited from working properly, and inhibition of another gene increases the length of life by 20%. The genes discovered affect a wide variety of activities, including insulin signaling, metabolism, and dietary regulation. Genes involved in insulin signaling are particul...

Anthrax inhibitors identified by Burnham team

...eatment for anthrax," said Dr. Pellecchia. "We are working on refining the chemical structure of the compound with the goal of achieving an even more potent and selective drug that should exhibit a higher degree of protection against anthrax." This research was supported by grants from the National Institut...

Wild grasses and man-made wheats advance research capabilities

...bnormalities. The second part of Rudd's research, working with synthetic or man-made hexaploid wheats, provides a more accessible bridge to the wild species, he said. Most synthetic hexaploid wheats are crosses between Durum (pasta-type) wheat, which has two genomes or sets of chromosomes, and Aegilops Tau...
