The safety tests that the government says will no longer use animals by the end of this year include the practice of giving ...

Animal experiments in the UK peaked at 4.14 million in 2015 driven mainly by a big increase at the time in genetic modification experiments. By 2020, the number had fallen sharply to 2.88 million as ...

In most developing tissues, signals called morphogens act like lighthouses, guiding nearby cells toward their fate and ...

Nature has managed to miniaturize the exact same vital organs and cram them into a less than one-centimeter-long frog. By Andrew Paul Published Sep 9, 2024 3:21 PM ...

Animal breeding has traditionally focused on improving mean trait performance; however, contemporary research increasingly highlights the significance of genetic variation not only in trait means but ...

We applaud the government’s bold new strategy working towards ending the suffering of animals in laboratories and promote ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...

Nature gave the world the dire wolf 2.6 million years ago, and then, through the hard hand of extinction, took it away—some 10,000 to 13,000 years ago when the last of the species died out. Now, the ...

When pandas eat their bamboo diet, they absorb small pieces of genetic material from the bamboo into their bodies, just like we do with the plants we eat. RNA is a single-stranded molecule made of the ...

Collectively, populations of Acanthocyclops vernalis, a species complex of freshwater copepods, are remarkably similar as to morphology and DNA content, despite variability in chromosome number.

Beagles are often used in laboratory animal testing. They are considered balanced, friendly to humans, and able to endure a lot. PETBOOK reports on the suffering they endure and what happens to the ...
