Extended Heredity book: An interview with the authors. Nongenetic inheritance approach

Should mendelian gene-centric view of heredity be completed by nongenetic inheritance factors? Extended Heredity: A New Understanding of Inheritance and evolution is a fantastic new book by Russell Bonduriansky and Troy Day about the role of nongenetic inheritance in evolution....

German Ethics Council statement about germline intervention overlooks current use of embryos in this line of research

Last year, the birth of the first genetically modified babies shook the world (see HERE). The German Ethics Council now presents a comprehensive ethical investigation into possible interventions in the genome of human embryos or germ cells. The Council does not deem the human...

In which measure people who feel happy or sad with the meaning of their lives are due exclusively to genetic factors?

Genetic determinism controversy. Can it determine the meaning of our life? If despite genetic macrodata it is difficult to identify somewhat complex disorders, some studies have dared to probe traits as diffuse as the propensity to crime, muscle power or academic performance. One...

First genetically modified babies case in China. Bioethics appraoch after latest offical investigations

After the statement from Chinese geneticist Jiankui He that he and his team had achieved the birth of the first genetically modified babies (that our Observatory covered extensively, see HERE), the Chinese government ordered an official investigation that has now confirmed the...

US authorizes the use of CRISPR directly in the patient’s body, until now the trials was made in cells extracted of the patient

Hopes and and concerns The first clinical trial involving the use of the gene editing tool CRISPR directly in the patient (see more ) has been approved in the United States. The trial aim to treat a congenital blindeness will include around 15 patients, adults and children, in...

Large-scale genetic studies do not include a racially and ethnically diverse population that greatly affects global health

A large study published in Cell titled The Missing Diversity in Human Genetic Studies affirms that the majority of studies of genetic association with disease have been performed in Europeans, what has a negative effect in global health, and proposes solutions (read entire...

Around the debate of CRISPR human experiments. New global registry is proposed and a moratorium in reproductive germline editing

There’s an “urgent need” to create a transparent global registry that would list all experiments related to human genome editing, an expert committee convened to advise the World Health Organization (WHO) said today. The international committee of 18 researchers and bioethicists,...

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...
