International scientists set up a rescue plan for the last three northern white rhinos (Ceratotherium simum cottoni) on Earth. The goal is to use the remaining three rhinos and tissue samples from ...

Similar to humans, planarians have brains, similar organs, and stem cells, so they are often used as model organisms for basic research. In addition, it is known that planaria has totipotent stem ...

Researchers have discovered, for the first time, a common molecular pathway that is used by both normal stem cells and cancer stem cells when they reproduce themselves. Researchers at Stanford ...

For the first time, scientists said Thursday that they had bred mice with two genetic fathers, steering around biological hurdles that would otherwise prevent same-sex parents from having offspring.

1. In many basal metazoans, both somatic and reproductive functions are performed by cellular derivatives of a single multipotent stem cell population. Reproduction can drain these stem cell pools, ...

Research by Austrian geneticists has raised the possibility that stem cells[1] could be isolated from amniotic fluid – the protective 'bath water' that surrounds the unborn baby. Geneticist Professor ...

Dr. Mark Hughes likes to startle audiences by declaring that sex may become outdated as a means of human reproduction. His field will replace it with technology, he submits. "It is going to be, 'Sex ...

In the intricate science of reproduction, the creation of offspring has long relied on the union of sperm and eggs, whether naturally or through assisted techniques like in vitro fertilization. Both ...
