Taking Aim With Nanoparticle PEBBLEs

...he targeted cell and shoot reactive oxygen species into it, setting off "an avalanche of damage," said Kopelman. By staying outside the cell, PEBBLEs avoid a problem that thwarts many chemotherapy drugs. "The really bad cancer cells get immune to chemotherapy drugs ?they pump the drugs back out," Kopelma...

ASU researchers finds novel chemistry at work to provide parrot's vibrant red colors

...ble, and then focused on "deconstructing the color into its component parts." McGraw said an interesting aspect of the five polyenal lipochromes that provide the red in parrots, is that the pigment is found only in the bird's feathers and nowhere else in the body of the bird, indicating that parrots manu...

While several laboratories have attempted to grow stem cells in alternative cultures, problems have remained. In some cases, human feeder layers were developed b...
