Sperm migration in the genital tract: computer simulations identify factors for success
During mating in wildlife species, males transfer millions of sperm into the female genital tract. On the way to the egg cell the sperm have to pass through the genital tract. Very few of the sperm cells actually succeed in…

Red Dead Redemption 2 teaches players about wildlife
Players of the popular game Red Dead Redemption 2 learn how to identify real American wildlife, new research shows. The game, set in the American West in 1899, features simulations of about 200 real species of animals. The new study,…
Zoo amphibians were on display while humans were locked away
While the UK was in lockdown, certain species of captive amphibians became more visible, a new study suggests. The COVID-19 pandemic forced the closure of zoos across the UK for several months from March 2020, with gradual re-openings from summer…
‘Smart collar’ could prevent tapeworms in dogs
Dogs infected with echinococcosis play a major role in spreading tapeworms across human populations around the world. Now, researchers have developed a “smart collar” which gradually delivers a steady dose of a deworming drug to dogs. The collar successfully reduces…

Researchers overcome winking, napping pigs to prove brain test works
URBANA, Ill. – If you’ve ever been to an eye doctor, there’s a good chance you’ve felt the sudden puff of air to the eye that constitutes a traditional test for glaucoma. It’s no one’s favorite experience, but the puff…
Arctic seabirds are less heat tolerant, more vulnerable to climate change
The Arctic is warming at approximately twice the global rate. A new study led by researchers from McGill University finds that cold-adapted Arctic species, like the thick-billed murre, are especially vulnerable to heat stress caused by climate change.
