As the climate changes, scientists are concerned about how well plants and animals will adapt to rapid warming. A new ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

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, ...

Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early ...

Researchers have created a replica of womb lining or endometrium which allowed them to study the implantation of human embryos — process that signals start of a pregnancy. Described in a paper in the ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Molecular mechanism uncovered in mice by UC Santa Cruz researchers reveals how a father’s diet, stress, and other ...
