| Molecular secrets of ancient Chinese herbal remedy discovered Posted: 12 Feb 2012 04:27 PM PST Researchers have discovered the cellular target for a two-thousand-year-old herbal remedy known as Chang Shan. The bioactive compound, called febrifugine, triggers a stress-response pathway that tells cells to conserve resources and eliminate unnecessary functions, which in turn blocks the production of dangerous, disease-causing immune cells.  |
| A mitosis mystery solved: How chromosomes align perfectly in a dividing cell Posted: 12 Feb 2012 04:25 PM PST Although the process of mitotic cell division has been studied intensely for more than 50 years, researchers have only now solved the mystery of how cells correctly align their chromosomes during symmetric mitosis.  |
