Asexual reproduction, in which females reproduce without males by cloning themselves, has been documented in multiple species ...

Bumblebees bring pollen from one flower to another, allowing the plant to fertilize their seeds. Salmon travel upstream to meet with other fish from the river and fertilize their eggs. Elephants mate ...

A team of stem cell scientists successfully spawned mice from two male parents that reached adulthood, a significant step, but they still have to figure out the mechanics of the gene modification. In ...

A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse -- a mouse with two male parents -- that lived until adulthood. Their results ...

Sharks, skates and rays adapt their growth and reproduction to changing food availability, a new study reveals.

For the first time, scientists have created a bi-paternal mouse – that is, a mouse with two male parents – which survived until adulthood. The breakthrough represents a huge step forward in the field ...

The researchers even coined a word for it, xenoparity, meaning “foreign birth”. It pushes the boundaries of what we mean by ...

In one of the largest studies of cancer susceptibility across bird species, researchers describe an intriguing relationship between reproductive rates and cancer susceptibility. In one of the largest ...
