Why it is so hard for humans to have a baby?

New research by a scientist at the Milner Center for Evolution at the University of Bath suggests that "selfish chromosomes" explain why most human embryos die very early on. The study, published in PLoS Biology, explaining ...

The black box behind embryonic development

DNA regulation is a critical process in a cell that allows it to fulfill its function. This process is key during pregnancy, when embryonic cells must develop into all cell types needed to form an embryo. An international ...

Act of sabotage determines mammalian embryonic development

Alternative splicing is a fundamental biological process that allows cells to make many different types of mRNAs and proteins from a limited number of genes. For many animals, including humans, it is a feature that is essential ...

Genes are switched on in the human embryo from the get-go

The finding that some genes are active from the get-go challenges the textbook view that genes don't become active in human embryos until they are made up of four-to-eight cells, two or three days after fertilization.

Researchers receive patent for identifying viable embryos

Since 1978 when the first test tube baby was born, in vitro fertilization (IVF) has become a reasonable option for couples that have trouble getting pregnant. Originally developed to help women with obstructed tubes, the ...
