Presents the latest studies, findings, and innovations related to animals, their behavior, cognition, health, and the environment.
Can a mouse be cloned indefinitely? Decades-long experiment has answers
Repeated cloning from a single mouse failed after 58 generations. Researchers say harmful DNA changes are to blame.
Mosquitoes’ butt cells tell them when to stop biting
Mosquitoes have an appetite dampener in their derrières. When mosquitoes’ bellies are full, special cells in their rectums block their bloodthirst , researchers report March 20 in Current Biology . The finding may unlock a way to stop the insects from biting in the first place.
The push to end animal testing is gaining steam, but technology can’t fill the gap yet
The FDA has released draft guidance that aims to clear up how drug developers can use alternative testing – but that doesn’t mean animal testing in the US is over.
Lab-grown oesophagus restores pigs’ ability to swallow
Engineered tissue could eventually be used for children born with gaps in their alimentary canal, or for adults whose muscles have been damaged by cancer.
Molecule in python blood could pave way for new obesity drugs, scientists say
Pythons follow the ultimate crash diet, swallowing an antelope in a single sitting and then going for months without eating. Now scientists have identified a molecule that appears to be crucial for this metabolic feat, and which they say could pave the way for a new class of obesity drugs.
Butterflies crossing oceans, moths navigating by the stars: unravelling the mysteries of insect migrations
Trillions of insects embark, largely unnoticed, on epic journeys every year across mountain ranges, deserts and seas, and it is only now, as their numbers suffer huge declines, that scientists are tracking their movements.
Platypuses share a surprising fur feature with birds
Platypuses just got weirder. As if a mammal that lays eggs, senses electricity with its bill and fluoresces isn’t enough of a headscratcher, now it appears platypuses also share a feature with birds.
A bonobo’s imaginary tea party hints that apes can pretend
Kanzi would sometimes play with imaginary juice and grapes, just as humans might. The bonobo's ability challenges old ideas about how animals think.
