Women have stronger immune systems than men -- and it's all down to X-chromosome related microRNA Posted: 27 Sep 2011 04:23 PM PDT As anyone familiar with the phrase "man-flu" will know women consider themselves to be the more robust side of the species when it comes to health and illness. Now new research seems to support the idea. The research focuses on the role of MicroRNAs encoded on the X chromosome to explain why women have stronger immune systems to men and are less likely to develop cancer.

Removal of fibroids that distort the womb cavity may prevent recurrent miscarriages, study suggests Posted: 27 Sep 2011 04:23 PM PDT Researchers have found the first, firm evidence that fibroids are associated with recurrent miscarriages. They have also discovered that if they removed the fibroids that distorted the inside of the womb, the risk of miscarriage in the second trimester of pregnancy was reduced dramatically -- to zero.

This knowledge may eventually help scientists and clinicians correct these misfires.

Biochemists identify new genetic code repair tool Posted: 27 Sep 2011 09:46 AM PDT Researchers recently reported finding a new class of DNA repair-makers. To ensure the integrity of the genetic material, cells are equipped with a "molecular toolkit" for repairing DNA damage. The toolkit is composed of a variety of different molecules -- called enzymes -- that have evolved to repair different types of DNA damage. Researchers have now discovered a new class of enzymes in that superfamily that lack the ability to repair uracil.
