How receptors govern inflammatory pain
...they said, there had been no studies that explored what
role the receptors played in whole animals. To study that role, the researchers genetically altered mice to lack one or another type of key component, or subunit, of the AMPA receptor protein. Knocking out one type of subunit, called GluR-A, would en...
Study shows stem cells can preserve vision
... needed in the damaged retina and had changed into what
looked like normal retinal cells. The scientists also found that many of the cone cells that were on the verge of dying before the transplant appeared to regain or retain their function. The researchers speculated that the transplanted cells were sec...

is or isn't a crossing in a given image. They used this technique to analyse 196 images and it proved successful in detecting whether there was a crossing present in 194 of them. In the two images where the system made a mistake, it said there wasn'...

Diamonds are a urologist's best friend
....' In addition to urinary catheters there are also what
are known as ureter splints (stents), which are inserted from the bladder right up to the kidney. For example, in ureteroliths or cases of cancer they ensure that the urine can be discharged without obstruction from the kidney to the bladder,' Dr. La...

science has come to recognize--mitochondria are quite dynamic and change shape in response to nutritional and hormonal cues. But we are the first to report that mitochondria essentially remodel their own membranes, and thereby their physical properti...

Scientists achieve self-assembly of spider silk fiber in insect cells
...avior of the proteins they produced as compared to what
occurs in nature shows a high level of sophistication in the spider fibers. It seems that the protein ADF-4 makes it possible for the rapid production of fiber, while the other protein, ADF-3, regulates production and prevents early fiber production,...

Livestock grazing study finds moderate grazing beneficial to Great Basin plant communities
... not the longest, study of its kind." To determine what
effects the grazing of large ungulates--cattle and sheep, for example--have had on such things as the amount and variety of vegetation, the research team conducted in 2001 to 2002 a meticulous examination of the ecologies both inside and outside the ...

the significance of low magnesium is, but there are some indications that it may be important to the bacteria's ability to survive in white blood cells or outside of the host in soil or water," Groisman says. When scientists transplanted the Salmonel...
