According to researchers at the Advanced Cell Technology biotech company, there are, as of now, no known barriers between us and the first cloning of a human baby, for reproductive purposes. They are now confident that they can clone humans not only for stem cells (when the embryo only lives a few days before being d... |

Although surprising, the new discovery confirms once again that freezing the embryos after fertilization does not harm them in any way. During a study regarding children born both as a result of conventional In Vitro Fertilization and through IVF using frozen embryos, Anja Pinborg of the Copenhagen University Hospita... |

Sexual reproduction may be a lot of fun, but it's far from being perfect when it comes to combining the genetic material of the parents, sometimes leading to incurable genetic diseases. However, genetically engineered children could literally be born perfect in a couple of years in the UK, by replacing defective... |

Are you eager to know the sex of your unborn child? Normally, you have to wait 4-5 months until ultrasound scanning can tell you that but, now, it is possible that you wait a shorter period of time. Many women are not even aware they're pregnant at the date when this new method can already tell them if it's... |

A new organism develops inside the woman's womb due to the placenta, a special organ for delivering food and oxygen from the mother to the fetus. A new research made at the Stanford University School of Medicine and published in the journal Genome Research has revealed the first genetic clues about the ancient o... |

We all start as egg cells. And after being fertilized, based on the information of the sex chromosomes, the new developing organism must turn into a male or a female. A new research published in "Journal of Clinical Investigation" shows that testosterone, the male hormone, is responsible for turning an embryo into a ... |

During the womb development, nipple will grow on front and the spine in the back. A team at the University of Auckland has also found why, in a research published in Nature Cell Biology. The gene Runx2 was already known to control bone development, but the researchers led by Dr Maria Flores, senior research fellow of... |

Common knowledge says that a child has two parents. But what about three biological parents? A team at the Newcastle University has created human embryos containing DNA from two women and a man, a technology that one day could be a therapy for couples, for getting kids free of genetic diseases. Still, these embryos a... |

Everybody is now focusing on the British research forecasting male-free reproduction. The team at the University of Newcastle has achieved proto-sperms from human female bone marrow cells. Many already think of lesbian couples conceiving their own children, possessing DNA 100% coming from both women, not 50% from one... |

Having an addiction problem? Well, this may mean that your mother did not eat well after conceiving you. A new research published in the journal "Addiction" shows that children whose mothers passed through a period of famine are prone to addictions later in life. The team from the Dutch mental health care organizatio... |

You already know this: the sex chromosome from your father dictated your sex: boy for Y, girl for X. It's the same case with all the mammals. The mother will always come with an X chromosome. But in reptiles, there are neither sex chromosomes, nor sex portions on the chromosomes. All the eggs have the potential ... |

A cloned Scarlet Johanson may be the dream of any man and a Californian company has just made the first step toward this purpose: for the first time, scientists have achieved cloned human embryos using DNA extracted from adult skin cells, as reported in the Stem Cells journal. "That's an important first step tow... |

In the end, there may be no need to kill human embryos for getting stem cells, as two teams have achieved embryonic stem cells from human skin cells. The newly induced pluripotent cells could turn into various cell types of the human organism. "The advantage of using [such] reprogrammed skin cells is that any cells d... |

The 2004 South Korean claim regarding human cloning proved false. Meanwhile, a team at the Oregon National Primate Research Center in Portland could have achieved the cloning of monkey embryos and the extraction of stem cells from them, a huge step towards human cloning. The research could be published soon in the sc... |

They may not produce eyes that have the color you prefer, but researchers have found a method of generating eyes starting with stem cells. At least eye tissues (like retina) could replace damaged parts in cataract, glaucoma, macular degeneration and other ocular conditions that impair vision, leading even to blindnes... |

We do not know when women will start to bear chimp offspring to save their species, but a Japanese team has already obtained trout from salmon parents. This could be crucial for saving many endangered species of fish.The team inserted germ cells (precursors to sperm and egg cells) from male trout (sperm precursor cel... |

Women already say that man is an appendix of the penis. As sex toys already replace the penis, only the sexual function remains. And when this will be gone, too, what will be men's fate? If amongst vertebrates, only sharks and some lizards have been known to reproduce without requiring sperm for fertilization, a... |

Couples undergoing IVF are struggling for years to have a baby and when this happens, it comes in a number bigger than 1, in at least 40 % of the cases. In fact, the latest cases of sextuplets are the result of IVF treatments. But the issue is that multiple pregnancies have worse outcomes and in many cases these bab... |

What seemed to be a great problem could turn into a boon: couple that have children through in vitro fertilization (IVF) apparently have them ...bigger and healthier! Previously, it was known only that these children have a low risk of developing congenital abnormalities. In the first long-term research monitoring th... |

There are organisms on Earth that can live without oxygen. Such is the case of archebacteria, that live in extreme environments that lack oxygen, like geysers, black smokers, oil wells, bottom of the lakes or oceans. They represent a basic stage, when the Earth lacked oxygen. Other organisms can live in anoxic enviro... |

The day when we will see the man-animal mutants from the Ninja Turtles on the streets is approaching. British ministers have allowed the creation of human-animal hybrid embryos for scientific purposes. Last year, a ban proposal made researchers fear that medical breakthroughs will be stopped. The research involving h... |

They say a mother is more than a father. That is true, as a mother invests more of its biology in the offspring anyway. During egg development (oogenesis), the mother deposits in it large amounts of messenger RNAs (mRNAs) and proteins. These mRNAs take over after the sperm did its job to orchestrate the emergence of ... |
