Brightening prospects of using fluorescent nanotubes in medical applications

... ways to use them in clinical applications.” The figure of merit for fluorescence is quantum efficiency: the ratio of the number of photons of light that a device emits to the number of photons it absorbs in the process. The VINSE team reports that they can produce populations containing trillions of nano...

'Smart' mice teach scientists about learning process, brain disorders

...ning than their normal cousins, and are quicker to figure out that their environment has changed, a team led by researchers at UT Southwestern Medical Center has found. The results, appearing today in the online edition of the journal Nature Neuroscience , reveal a new mechanism of learning in the brain...

For many insects, winter survival is in the genes

...erance in insects." He said the next step is to figure out the unique functions of each heat-shock protein. "We assume it's not simply redundancy in the system, but that each protein makes a unique contribution somehow," Denlinger said. "This protective mechanism is much more complex than we envisione...

Brain's white matter -- More 'talkative' than once thought

...Bergles and his team studied nearby nerve cells to figure out where the glutamate might be coming from. By forcing single nerve cells to become excited one at a time, they discovered that as electrical impulses are carried along the nerves, glutamate is released and causes electrical signals in the OPCs....

Anthrax paralyzes immune cells with lethal toxin, UF research shows

... Southwick said. "In an individual cell, you can't figure out where the actin is assembling and what's controlling it. But Listeria seems to use the same pathways that a cell uses to crawl. So anything that blocks Listeria we predict would also block neutrophils from crawling. And that's what we found."...

Newborn neurons like to hang with the 'in' crowd

...s Toni, Ph.D., who headed the current study. To figure out how the newcomers do it, the Salk researchers injected a virus carrying the gene for green fluorescent protein into the hippocampus, a brain region harboring neural stem cells that give rise to new neurons. Newly born neurons infected with virus ...

HIV survival improves if patients stay in care

...sits in all four quarters. "The next step is to figure out how to get them to stay in care," said Giordano. He plans to look for ways to intervene in this process. He is now studying a group of people who are newly diagnosed with HIV in Houston to evaluate the effects of knowledge about the disease socio...
