One of the four ingredients in the genetic recipe that scientists in Japan and the U.S. followed last year to persuade human skin cells to revert to an embryonic stem cell state, is dispensable in ES cells, thanks to the presence of molecular alliance between specific group of key proteins known as transcription factors, a research team led by Genome Institute of Singapore under the Agency for Science, Technology and Research reports in current issue of Nature Cell Biology.

Chemical peels using either alpha-hydroxy acid or beta-hydroxy acid are both highly effective in treating mild to moderately severe facial acne, researchers at the Saint Louis University School of Medicine have found - the first study to compare the two different types of acid peels as therapies for the skin disorder.

The compound sulforaphane whose natural precursors are found at high levels in broccoli and other cruciferous vegetables has been hailed for its chemopreventive powers against cancer.

Researchers at the University of Pennsylvania School of Medicine have found that hair follicles in adult mice regenerate by re-awakening genes once active only in developing embryos. These findings provide unequivocal evidence for the first time that, like other animals such as newts and salamanders, mammals have the power to regenerate. These findings are published in the May 17 issue of Nature.
