Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

...ically damaged cells. The researchers thought that getting a working version into the cancer cells would increase the effectiveness of chemotherapy and radiation, which cause such damage in the course of treatment. In preclinical work, Chang and her group found that the nanoparticle-p53 therapy enhanced c...

Researchers know what you were about to say; fMRI used to detect memory storage and retrieval

... a common frustration. "An every-day strategy for getting at lost memories involves using a part of a memory to pull out the entire thought, much like when you try remember where you put your keys last night," Polyn said. "If you recall that you were washing dishes, that might trigger associated memories, ...

Bacterial protein mimics host to cripple defenses

...e biochemical clues to what AvrPtoB was doing, but getting the three-dimensional crystal structure was really key," Martin explained. To find that structure, Martin and Abramovitch worked with collaborators at Rockefeller University. The structure of AvrPtoB revealed that the protein looks very much like a u...

Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning

... have been able to shed light in that black box by getting a particular class of insects to expose the key underground carbon traffic system - by eating it. The University of Warwick team worked with researchers from Aberdeen, Lancaster and Sheffield, to try and establish if plant associated fungi - arbulsc...

New battery technology helps stimulate nerves

...based compounds, scientists -- and patients -- are getting a significant new charge out of the tiny lithium batteries used in implantable devices to help treat nervous system and other disorders. The lithium battery is the workhorse in implantable devices -- stimulators used to jump start the heart and help...

Overfishing may drive endangered seabird to rely upon lower quality food

...d nests," he said. "But it's possible that they're getting a double whammy. Not only are they losing their nesting habitat, they're also experiencing a degraded prey environment." The researchers pointed out that the U.S. Fish and Wildlife Service has recently decided to start the process to remove the marb...

Engineered Stem Cells Show Promise For Sneaking Drugs Into The Brain

... diseases and other neurodegenerative disorders is getting medicine to the right place in the brain. The brain is a complex organ with many different types of cells and structures, and it is fortified with a protective barrier erected by blood vessels and glial cells -- the brain's structural building block...

Worms know bad food when they smell it

Scientists crack code for motor neuron wiring

...pinal cord injuries, much attention has focused on getting the axons of cortical neurons to grow past the lesion site and innervate target neurons in distant parts of the spinal cord," he said. "Now, it may be that the spinal cord circuit is still intact -- and there is some evidence to believe this -- so al...
