International discussion has been proposed about ethical use of embryoids, human embryo-like organoids in experiments

An article published in Nature, signed by notable personalities in the area of bioethics, discusses the ethical implications of embryoids (organoids) or embryo models, in vitro cell aggregates that model various regions of the embryo to allow their study. These studies are framed...

Human–animal hybrid advisability. Human brain gene introduced into monkeys that seems to increase their intelligence

“Genetic changes should not be introduced in higher animals, as this raises bioethical uncertainties.” Chinese scientists have recently produced transgenic monkeys by introducing a human brain gene into the animals during their embryonic development (produci...

Russian scientist is waiting for the approval of the government to produce babies with a modified genome

Denis Rebrikov, a Russian molecular biologist, has made public his intention to modify the genome of human embryos and then implant them in women to produce genetically modified babies as soon as he can obtain the necessary permits, according to the journal Nature (see HERE)....

Promising experiment with CRISPR. It corrects a lung disease in mouse fetuses but this research still has certain limitations

One step forward in the possibility of applying CRISPR in utero to correct diseases The CRISPR gene editing tool has been applied in utero in mice to correct a mutation that causes a lethal lung disease in mice. These experiments, published recently in Science Translational...

New possibilities increase the identification of fetal chromosomal anomalies

New possibilities open up in the study of the fetal genome In a recent Editorial in The Lancet, the author discusses an article published in the same journal (see HERE), which describes the study of the fetal genome after birth to detect if there are abnormalities that can...

Could CRISPR gene editing tool eradicate entire species? Spanish Institute releases a campaign to eradicate cockroache

Could cockroaches enter in the category of endangered species? Researchers at the Institute of Evolutionary Biology in Barcelona want to use the CRISPR gene editing tool to eradicate cockroaches. The strategy would consist of expanding a harmful genetic trait (sterility) in the...

International Congress in Madrid debates about “Transhumanism and genetically altering people”

Genetic manipulation, which until now only took place with food, is now possible in humans. Additionally, there are electronic devices that can improve intellectual capacities and put an intense ethical debate on the table. Scientists, specialist in bioethics, jurists,...

Anonimity of gametes donation current legislation has come under increased scrutiny. Bioethical approach

“In contemporary culture young people have strong moral claims to know their genetic identities”. Determining whether gamete donation, especially of semen, should be anonymous is an open bioethical debate that still remains unresolved (read HERE our report). Furthermore, from a...

Bioethics of artificial genomes. New method to produce minimal genomes is discovered. Does it really create life?

On 1 April this year, the journal PNAS published an interesting article in which Swiss researchers described how they obtained a minimal artificial genome. Obtaining minimal genomes, which contain only the genes that are essential to maintain the life of an organism, are one of...

Another molecular revolution. The atlas of human embryonic development

We publish the full text of the article published in the Civica magazine last January (Spanish version HERE) that we consider of great bioethical interest. By now, at this advanced stage of biology in which we find ourselves, no one should doubt that each human individual, each...
