Women who suffer repeated unexplained miscarriages can be helped to have babies if preimplantation genetic diagnosis (PGD) is carried out on their embryos before they are placed in the womb.
Ms Carmen Rubio told the European Society of Human Reproduction and Embryology annual conference in Vienna today (Monday 1 July) that her research showed that chromosomal abnormalities (aneuploidies) in the embryos were important causes of unexplained recurrent miscarriages (RM) and implantation failure (IF). She and her colleagues had achieved normal pregnancy rates and a decreased risk of miscarriage in women with these conditions by screening the embryos for chromosomal abnormalities during IVF and transferring only the normal embryos to the women’s wombs.
Ms Rubio, co-ordinator of the PGD programme at the Instituto Valenciano de Infertilidad, Valencia, Spain, said: "We know already that non-inherited abnormalities in the number of chromosomes is a common cause of miscarriage and that embryos which fail to implant successfully during IVF and ICSI often have these abnormalities as well. We wondered whether chromosomal abnormalities, produced while the male or female sex cells are being formed, or during the early development of the embryo, might be an important factor in women with RM or IF."

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
