Scientists solve 30-year-old mystery of mutant mouse's kidney woes

...kidney collecting duct epithelium. His lab also is looking for other genetic factors that contribute to renal diseases. ...

Fire ant-attacking fly spreading rapidly in Texas

... control system." Gilbert and his colleagues are looking at the fire ant-fly relationship in parts of Argentina that are similar to habitats in Texas. "It is rewarding to see the first species expanding over more than four million acres of Texas," says Gilbert, "but we've failed miserably in parts of Tex...

Stem cell expansion

...tible to infections. Consequently, researchers are looking for ways to expand HSCs prior to transplantation. HOXB4 is known to be involved in stem cell maintenance and had shown some promise for stem cell expansion in mice. To investigate the potential of HOXB4 treatment for HSC expansion before transplantat...

Parasitic plants sniff out hosts

Parasitic plants do not haphazardly flail about looking for a host but sense volatile chemicals produced by other plants and identify potential hosts by their emissions, according to a team of Penn State chemical ecologists. "We are interested in how plants respond to their environment, and have looked a...

Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere

...tists searched genome fragments of these plankton, looking for specific gene sequences that would show how the plankton use sulfur compounds. "This breakthrough in the microbial physiology of DMSP metabolism opens the door to understanding the biology and ecology of this globally important process," said W...

With record resolution and sensitivity, tool images how life organizes in a cell membrane

...use cell membranes are not pure materials. ''We're looking at mixtures of things, and we want to be able to s...of each type of lipid resided in an area. ''We're looking for lateral organization of some sort believed to be present in membranes,'' Boxer said. ''There is ...

Epstein-Barr virus might kick-start multiple sclerosis

...S-like disease," said Edwards. "So we knew we were looking at the right population of T cells." The next step will be to determine how these over-reactive immune cells trigger the destruction of the myelin sheathing that insulates nerve cells. "The broadened response of the T cells could lead them to recog...

Ghost protein leaves fresh tracks in the cell

...ubreuil and his UIC co-workers have spent a decade looking at different types of cells -- mostly epithelial -- trying to learn what cues tell spectrin where to assemble in cells. They use the fruit fly as their test animal because its genetic makeup has many striking similarities to humans. "In our study, ...

Mayo Clinic Cancer Center: Harnessing the measles virus to attack cancer

...in patients using measles to kill cancer. "We are looking at better ways to treat some of the most lethal ca...c Cancer Center's Molecular Medicine Program began looking into it, resulting in the current study and other related projects. "Mayo is the perfect place to ...

Mobile DNA part of evolution's toolbox

... reports to grow. "It's a very exciting time to be looking at the human genome, because there's an enormous amount of DNA that we know is important, but we don't yet know what it's doing." ...

Nice guys do finish first in lizards' evolutionary race

.... Side-blotched lizards spend their year on earth looking to reproduce, and their strategies have lessons about evolution. An article in the May 9 edition of the Proceedings of the National Academy of Sciences provides the first genetic evidence of a trait that the animals recognize and use ?even if that tr...

High-tech research shows cocaine changes proteins and brain function

...researcher used technology so advanced it was like looking for differences in brain tissue with "floodlights" rather than a "flashlight," he said. Hemby and his colleagues analyzed thousands of proteins from brain tissue obtained from individuals who died of cocaine overdose and compared these "protein profi...

New angiogenesis finding may help fight cancer growth

...ow Soumen Paul, began the new study, they were not looking into angiogenesis. Instead, they were studying a p...of Chemistry. Bresnick and his collaborators are looking further into how the molecule works in human cells and in mouse models of angiogenesis. Eventual...

Light-sensitive photoswitches could restore sight to those with macular degeneration

...with other molecules that can force shape changes, looking for improved ways to attach shape-changing molecules to proteins, developing means to shuttle these photoswitches into cells, building artificial genes that can be inserted into a cell's DNA to express the photoswitches in the correct cell, and searc...

Coffee makes us more likely to say 'yes'

If you're looking for a way to make someone say 'yes', coffee can help. Moderate amounts of caffeine can have an impact on the extent to which we can be persuaded, finds research published today in the European Journal of Social Psychology. The Australian researcher...

The appearance of your hands can reveal your age, study finds

Copying nature could save us energy, study shows

...engineering challenges. Researchers are currently looking at the desert cockroach (to develop a new kind of dehumidifier technology), insect sense organs (for structural health monitoring) and the egg-laying organ of a wood-wasp (for a new type of steerable endoscope). "Evolution has sculpted animals, inse...

OHSU study says stem cell 'fusion' occurs in tumors

...lls fused. One test to prove cell fusion involved looking for the presence of Y chromosomes, or male-characteristic DNA, within the female donor cells marked with a green fluorescent protein. About 60 percent of the epithelial cells were positive for both donor and recipient cell markers. A second test conf...

UBC researchers find stroke death channel

...oke, but nobody knew the exact process ?so we went looking for the death channel. And we found it," says Roger Thompson, a UBC Psychiatry post-doctoral Fellow who made the discovery, along with graduate student Ning Zhou and Psychiatry Prof. Brian MacVicar, all members of the Brain Research Centre at UBC Hos...

New understanding of parasite cell structures may provide treatments for serious tropical diseases
