Period-lengthening/-shortening molecules can change the biological clock rhythm. A team of chemists and biologists at the Institute of Transformative Bio-Molecules (ITbM), Nagoya University have succeeded in finding new molecules that change the circadian rhythm in mammals by applying synthetic chemistry methods, which makes use of highly selective metal catalysts.

Fluorescence microscopy of maternal and paternal chromosomes is shown at the first mitosis during the oocyte to embryo transition in the mouse. Researchers in the University of Georgia's Regenerative Bioscience Center are visually capturing the first process of chromosome alignment and separation at the beginning of mouse development. The findings could lead to answers to questions concerning the mechanisms leading to birth defects and chromosome instability in cancer cells.
