Two recent research papers published in Science and PNAS have reignited the debate on Down syndrome, gene editing, and the ethical limits of biomedical research. While one of the studies analyzed the molecular alterations in fetal brain development in fetuses with trisomy 21 obtained [...]
The possibility of genetically modifying human beings no longer belongs solely to the realm of science fiction. Rapid advances in gene-editing techniques such as CRISPR have generated intense scientific, ethical, and social debate about the limits of intervention in human [...]
CRISPR gene editing has evolved over the past decade from an experimental tool to a therapeutic platform with clinical trials in multiple areas: hematology, oncology, and rare, infectious, and metabolic diseases. In 2025, over 65 clinical trials evaluated CRISPR technologies or [...]
In Canada, the insistence on promoting euthanasia or “Medical Assistance in Dying” (MAiD) has reached the point of being repeatedly offered to patients who do not suffer from terminal illnesses. A representative example of this worrying trend is the case [...]
The recent death of J. Craig Venter prompts a reflection on the legacy of one of the most influential figures in the contemporary genomics revolution. From the intense scientific rivalry that marked the Human Genome Project to the development of synthetic biology, his career [...]
Tattoos have ceased to be a simple aesthetic expression and have become the object of growing scientific and health concerns. New epidemiological studies link certain inks and their accumulation in the body to an increased risk of lymphoma and skin [...]
A recent study published in PNAS presents a breakthrough in Down syndrome research by optimizing a strategy to silence the extra chromosome 21 (primarily responsible for the disorder) through integration of the XIST (X-inactive specific transcript) gene using CRISPR-Cas9 technology. This approach, [...]
Recently, the President of Uruguay, Yamandú Orsi, signed a decree regulating Law No. 20.431, which regulates euthanasia and the right to a dignified death, recognizing the possibility for individuals to request it in accordance with the provisions of the law. [...]
On March 26, the IOC published a document outlining its new policies regarding the participation of transgender women in Olympic competitions. These new regulations will apply starting with the Los Angeles Olympic Games in 2028 and are not retroactive. The [...]
International experts analyzed at the Catholic University of Valencia the possibilities, limits and bioethical challenges posed by gene editing and the creation of organoids. On April 20, the Bioethics Observatory at the Catholic University of Valencia (UCV) held its annual [...]
Gamete donation in assisted human reproduction is a topic that generates considerable debate in bioethics, centered mainly on the discussion of how to accommodate the wishes of the intended parents while respecting the rights of the children, who should always remain the [...]
A recent study presents a systematic review of clinical observational studies and preliminary studies analyzing the possible relationship between COVID-19 vaccination and the prevalence of different types of cancer. Among its conclusions, it states that the evidence collected in the [...]
