An international team of scientists led from Sweden's Karolinska Institutet has for the first time mapped all the genes that are activated in the first few days of a fertilized human egg. The study, ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

New study finds microgravity disrupts sperm and embryo development, raising concerns about human reproduction in space.

Over the past few decades, growing evidence has challenged the belief that inheritance is governed solely by DNA sequences. Scientists now recognise the crucial role of epigenetic inheritance – the ...

A team of researchers from Tohoku University, the National Center of Neurology and Psychiatry, and National Yang Ming Chiao Tung University has uncovered a novel molecular mechanism through which ...

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...

Learn how microgravity could affect sperm, fertilization, and embryonic development in space.

Konstanz researchers identify an enzyme that plays a role in the migration of cells in our body—not only during normal tissue formation and wound healing, but also when tumor cells metastasize. This ...

The United States’ announcement of building a residential base on the Moon within 10 years has drawn attention, amid research suggesting that human settlement in space across generations may be ...
