Measuring Protein Movements With Nanosecond Resolution Mar 19, 2010
13, 2008) Scientists have characterized a mechanism that allows for asymmetrical cell division during meiosis in oocytes. By tracking chromosome movement in live mouse oocytes, they have discovered that. (Science Daily)
Large-scale transcriptome data reveals transcriptional activity offission yeast LTR retrotransposons Mar 12, 2010
Transcriptome data collected during meiosis suggests that transcription of solitary LTRs is correlated with the transcription of nearby protein-coding genes. Conclusions. (BioMed Central)
Advance in Asexual Plant Reproduction Mar 9, 2010
In apomixis, reproductive cells retain the full complement of chromosomes, rather than losing half their genes via meiosis, as happens in sexual reproduction ... Instead of carrying half of the species' chromosomes, they carried the full complement of genetic material -- implying that they had not undergone meiosis. (Science Daily)
African Pygmy Mice: Females Are XY Feb 25, 2010
(May 17, 2005) Cornell University researchers Stephanie Correa, Elizabeth Adkins-Regan and Patricia Johnson have published a study that found that several bird species use progesterone during the first meiosis to. . (Science Daily)
First Discovery of the Female Sex Hormone Progesterone in a Plant Feb 7, 2010
(May 17, 2005) Cornell University researchers Stephanie Correa, Elizabeth Adkins-Regan and Patricia Johnson have published a study that found that several bird species use progesterone during the first meiosis to. (May 26, 2009) Researchers have just defined the reproduction cycle of the Spanish Lynx. (Science Daily)

Although mitosis and meiosis both involve cell division, they transmit genetic material in very different ways. What happens when either of these processes goes awry. (Nature News Service)
Nature Reviews Genetics Jan 10, 2010
Meiosis is a necessary part of gamete formation and sexual reproduction. It has been examined extensively in yeast but, although key components are evolutionarily conserved, studies in mammals are revealing important differences, and such work will enable progress towards the treatment of human infertility.
