It is affirmed that intrauterine exposure to a major psychological maternal stress affect son longevity in adulthood There is abundant medical evidence that exposure to adverse circumstances during the first few months of pregnancy can affect the vulnerability of the newborns in...

The human embryo mapped in three dimensions. Technique and bioethical approach

A team of researchers from the Institut Vision in Paris and the Jean-Pierre Aubert Research Centre, under the direction of Alain Chedotal, have managed to map the human embryo  in three dimensions (see HERE the published study), which, they believe, permit better understanding of...

CRISPR. Viable human embryos genetically edited in the USA. Technique and ethical controversies

Numerous complications could go unnoticed in this study On 26th July, the journal MIT Technology Review  announced that the CRISPR technique (see HERE) had been applied in human embryos for the first time in the United States, in a study led by embryologist Shoukhrat Mitalipov of...

Pre-embryo. This term is no longer used in current discussions regarding the nature of the embryo

Everything suggests that the term has been artificially created to justify the use of embryos for IVF and biomedical experiments A recent article has studied the use of the term “pre-embryo” (see “Determining whether the preimplantation human embryo is a living...

Legal status of human-animal chimeras – hybrid embryos

In addition to the biomedical and bioethical problems raised by human-animal hybridization, there are also objective legal problems. A recent article in the Journal of Medical Ethics (2014; 40, 284-285) reviewed this topic following a debate in the United Kingdom (UK) House of...

The amazing finding of senescent cells in embryos. Until now, these cells had been found only in aging tissue

The discovery raises the possibility that the start and end of life are intimately connected The process by which cells cease multiplying is known as senescence. In 1961, biologists Hayflick and Moorehead cryoconserved human fetal cells and found that these divide around 50 times...

Genome sequencing in foetal .This prenatal diagnosis arrises a new level of complexity to medical, family and social decisions

Regardless of the legal judgment that abortion deserves in different countries, any action that may induce or facilitate abortion is ethically unacceptable. In 2012, a technique was developed that enabled the foetal genome to be determined in the first trimester of pregnancy,...

The biological status of the early human embryo. When does human life begins?

“Those who argue that that embryo can be destroyed with impunity will have to prove that this newly created life is not human. And no-one, to the best of our knowledge, has yet been able to do so.” Introduction In order to determine the nature of the human embryo, we need to know...

Is the human embryo a living being of our species?

Few doubts that determining whether the preimplantation human embryo is a living being of our species is one of, if not the most, fundamental issues in modern bioethics. Another thing is whether that living biological being is, or is not, a human person. That, however, is another...

Changes occur in the maternal brain that enhance communication with the unborn child

Changes occur in the brain of pregnant women as a result of the new hormone levels and biological adaptation to them. According to an article published in Nature Neuroscience (see HERE), which essentially translates into a reduction in the volume of grey matter. This appears to...
