Most common lung cancers may begin in newly discovered cells

...said first author Carla Bender Kim, a postdoctoral fellow in the lab of senior author Tyler Jacks, a Howard Hughes Medical Institute investigator at Massachusetts Institute of Technology. "Cancer cells can continue to divide many times. Likewise, stem cells can divide over the lifespan of the organism. Also...

Say what? Bacterial conversation stoppers

...nces -- between co-mingling species. Postdoctoral fellow Karina Xavier mixed E. coli, beneficial bacteria that live in the human gut, with Vibrio harveyi, a marine species that naturally glows in the dark in the presence of a crowd. In the test tube, AI-2 production by either species turned up the ma...

'Jumping genes' contribute to the uniqueness of individual brains

...lls all over the brain in our mice," says research fellow and co-author M. Carolina N. Marchetto, "because then we knew it happened in vivo and couldn't be dismissed as a tissue culture artifact." Transposable L1 elements, or "jumping genes" as they are often called, make up 17 percent of our genomic DNA b...

Researchers create infectious hepatitis C virus in a test tube

...rst author Brett Lindenbach, Ph.D., a postdoctoral fellow in Rice's lab. "Our method replicates and produces virus particles that can infect new cells, initiating replication in them and leading to the production of more virus particles." Although little is know about the HCV life cycle, researchers think ...

Brain size may depend upon how neural cells are cleaved

...stitute investigator Li-Huei Tsai and postdoctoral fellow Kamon Sanada, both at Harvard Medical School, published their findings in the July 15, 2005, issue of the journal Cell. The researchers drew on studies by other researchers that showed that the orientation of cleavage planes in dividing neural proge...

Primate virus jumps species barrier to humans for first time in Asia

...f human disease yet. However, Jones-Engel and her fellow researchers warn that there are other primate viruses known to be harmful that could jump the species barrier. They don't want people to be afraid of coming in contact with macaques or other primates, but they do urge people to be cautious and carefu...

Hopkins scientists uncover 'tags' that force proteins to cell surface

...ght-building-block-long protein bits, postdoctoral fellow Sojin Shikano uncovered 65 that forced a normal protein to leave the cell's protein-building factory and go to the cell surface. By searching sequences of known human proteins, the researchers then identified those that use variations of the most pot...
