How adult fly testes keep from changing into ovaries

Posted: Published on November 14th, 2014

Nov 13, 2014 New research in flies shows how cells in adult reproductive organs maintain their sexual identity. The study, publishing online on November 13 in the Cell Press journal Developmental Cell, also identified a mutation that can switch the cells' sexual identity. The findings could lead to new insights on how to alter cells for therapeutic purposes. Sperm and eggs are made from germ cells, but instructions from their neighboring support cellscalled somatic cellsare also essential for their development. By studying the formation of sperm in fruit flies, which is remarkably similar to the process that occurs in people, investigators serendipitously found a mutation that gave testes a very unusual appearance. "Rather than becoming sperm, germ cells were stuck at an early stage, and they were surrounded by support cells that looked suspiciously like those belonging in an ovary," says senior author Dr. Erika Matunis of The Johns Hopkins School of Medicine. Her research team found that the mutation blocked the function of a specific gene in the stem cells that becomes support cells in the testis, causing the fruit flies to change from a male to a female identity. The research is the first to show that adult … Continue reading

The structure of cartilage noted in the Quran

Posted: Published on November 14th, 2014

Information about the stages of human development inside the mothers womb is provided in the verses of the Quran. It is said in verses that the bones form first in the womb, muscles then appear and surround these bones: ... then formed the drop into a clot and formed the clot into a lump and formed the lump into bones and clothed the bones in flesh; and then brought him into being as another creature. Blessed be Allah, the Best of Creators! (Surat Al-Muminun, 14) Until recently, the bones and muscles were thought to develop together inside the womb. However, advances in the science of embryology, which studies development inside the womb, have revealed that this is incorrect and the description in the Quran is absolutely correct. Microscopic examination also shows that development in the womb takes place exactly in line with the description in verses. Cartilage forms first in the embryo after which this cartilage tissue turns into bone. Subsequently, muscle cells are selected from the tissue around the bones and come together around them. As we have seen, the findings of modern embryology are in complete agreement with the stages of human development revealed in the Quran. Cartilage … Continue reading
