The scientific dogma that only mother’s mitochondria is inherited has been questioned which could could affect various major lines of investigation

This discovery has been a shock for those fields that are based on this “dogma” of biology, such as the study of human evolution or the development of nuclear transfer techniques Until very recently, it was thought that mitochondria, small cellular components...

Single-cell sequencing tool opens up promising possibilities in life cycle and biomedical research

In life cycle the biologic synchronous web that shape it is still a mystery, now a new avenue of research is open Every plant, animal and fungus is made up of an intricate amalgam of cells. Each cell type has its own unique function, life cycle, and reaction to its environment....

Same-sex parents produced in mammals. Mouse pups obtained from “exclusively” male or female pairs

See video below Scientists have managed to produce mouse pups , i.e. bimaternal or bipaternal, in experiments that have been published in Cell Stem Cell. In the aforementioned study, fertile mice were obtained from two females, and mice from two males were born from surrogate...

Legal aspects to take into account in the case of genetically modified babies in China

INTRODUCTION The news has come to light in numerous media: Chinese researcher He Jiankui and his team at SUSTech (Southern University of Science and Technology of China) in Shenzhen have produced the first two genetically-modified human beings using the CRISPR-CAS9 technique...

Scientific institutions are trying to devise global safeguards to stop rogue gene-editing of human embryos

Some U.S. researchers knew of a Chinese scientist’s intentions to implant edited embryos but were unable to stop him. A recent article makes an update of the measures that the scientific community is implementing to avoid implantation of edited embryos. It says  Now, nearly two...

Will be anonymous’ sperm donation a thing of the past? IVF people claims for their right to know

Thanks to DNA tests and the internet but mainly to the mobilization of IVF people to defend their right to know the identity of their biological parents, many persons could find their biological parents despite the fact that the law that protects the anonymity of gamete donor is...

CRISPR-mediated therapeutic editing corrects a genetic disease in mice’s fetuses. May it pave way in humans?

Researchers at the Children’s Hospital of Philadelphia Institute (CHOP) and the University of Pennsylvania have published the first proof-of-concept demonstrating the possibility of using CRISPR gene editing to cure diseases in utero (Nature Medicine). Using this strategy, they...

“Gene-edited babies” in China. What has said the coinventor of CRISPR technique, Jennifer Doudna?

Jennifer Doudna said, “It is a matter of when and where the gene editing technology will be used in human embryos”. As we commented HERE a Chinese scientist claimed he has used the CRISPR gene-editing science to produce two infants who will be resistant to HIV...

Cocaine effects and overdose successfully treated with CRISPR gene editing in mice

Researchers at the University of Chicago have used the CRISPR gene editing tool to treat cocaine addiction in mice, and suggest that it will be feasible to use this treatment in people. Methodology. Producing an artificial enzyme  The study, published in Nature Biomedical...

Current knowledge does not justify universal genetic tests for newborns, scientists and ethicists affirms

As discussed in an article in The Lancet, Francis Collins, director of the United States National Institutes of Health – NIH, said in 2014 that “over the course of the next few decades, the availability of cheap, efficient DNA technology will lead to a medical...
