Beattie, M.S., UCSD Department of Pediatrics and the Whittier Institute, said that "it will be rather simple now to develop a specific defined medium that allows for the ma...

Scientists develop new color-coded test for protein folding

...ology, we believe it will eventually be useful for testing other, more complicated proteins," Zare said, noting that a gold nanoparticle sensor could turn out to be a quick and inexpensive way for doctors to identify antibodies and other signs of infection in the blood stream. Over the next few months, he an...

The research was supported by grant from the NIH and a Howard Hughes Medical Institute predoctoral fellowship to Casey graduate student Ann M. Winter-Vann, the first author of the study. "This is the first s...

Tiny scaffolding allows stem cells to become working fat cells

...ach might have commercial applications as a way of testing new drugs. "Small, three-dimensional cell colonies could be grown on multi-well assay plates and be used to test dozens of compounds at the same time," he explained. "Since these cells better resemble how cells function in living tissue, they would ...
