Untangling Twinning What Science Tells Us About the Nature of Human Embryos by Maureen L. Condic

Scientists and philosophers have long struggled to answer the questions of when human life begins and when human life has inherent value. The phenomenon of identical (monozygotic) twinning presents a significant challenge to the view that human life and human personhood begin at conception.

Stem cells used to model a two-week-old human embryo
Researchers have used stem cells to create models that resemble human embryos at two weeks old, but bypass the earliest developmental stages — paving the way for studies that are not possible in human embryos.

BMBF conference
#HumanEmbryos in #MedicalResearch:
Taboo? - Justifiable? - Chance?

In the workshop "Framework of research on and with human pluripotent stem cells and human cellular entities (-oids)", key issues and framework conditions of new legislative initiatives were intensively discussed. Afterwards, Dirk Lanzerath presented the outcomes to the plenary and the Ministry.

Human embryos in medical research: Taboo? - Justifiable? - Opportunity? - DLR Gesundheitsforschung

Research on early embryos and cell structures generated in laboratories offer new perspectives for health research and medicine. Meanwhile ethical questions arise. A conference provides the opportunity for critical reflection and discussion.

Developing human embryos imaged at highest-ever resolution
Non-invasive imaging approach could lead to innovations in embryo screening.
Researchers have captured the most-detailed images yet of human embryos developing in real time, using two common laboratory tools — fluorescent dyes and laser microscopes.

What the Law and Bioethics Tell Us About Synthetic Human Embryos

A synthetic embryo can now be constructed from very early pre-embryonic cells – without the need for an egg or sperm. These were initially created in mice. In April, Chinese researchers created synthetic monkey embryos. Last month, the first synthetic human models were reportedly created. This development throws a moral monkey-wrench into the current moratoria on embryonic research after 14 days. But there are more problems ahead.

Exclusive: Breakthrough could aid research into genetic disorders but raises serious ethical and legal issues

The Guardian
Do human embryos and cancer share the same starting fuse?

At the moment of fertilization, the genes in the fertilizing sperm and egg are switched off. For a new embryo to develop, they must be switched on—but how?
