Young mice seemingly attempt to revive an anaesthetised cage mate by grooming and biting it and will even pull aside the tongue to clear its airway ...

After one mouse was rendered unconscious following a woozy dose of anaesthesia, several first-aider mice were seen piling in ...

Jan. 28, 2025 — 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.

The researchers conducted a series of tests that involved presenting mice with two companions: a familiar cage mate that was under anesthesia and another mouse that was conscious and moving around.

In a lab at the University of Southern California, a mouse notices something is wrong. Its cage mate lies motionless, unresponsive. Without hesitation, the mouse begins to sniff, groom, and then — ...

In the lab, the researchers let some female mice mate with a male they were interested in, while others were set up in "arranged" matings. The researchers then tested the babies immune systems.

not just mice, with a transmitter and receiver for genetic information that could influence mate choice.

For this research, the scientists therefore required mice with a genetic makeup that was as consistent as possible. A breakthrough was achieved in 1909 when researchers managed for the first time to ...
