Japanese chin dogs had some of the highest rates of brachycephalic obstructive airway syndrome in the study. 

These 12 Popular Dog Breeds Are at Risk of Breathing Problems Related to Their Short Snouts, a New Study Suggests

Past research on brachycephalic obstructive airway syndrome—a chronic, hereditary disease associated with flat faces—has focused mainly on just three breeds

Based on Andrewsarchus’ skull size and the skull-to-body-size ratios of other hoofed predators called mesonychids, scientists estimated in 1924 that the beast was more than 12 feet long and about 6 feet tall. Reassessments of Andrewsarchus’ evolutionary tree, however, suggest this estimate is inaccurate.

This Giant Carnivore Ran on Hooves. Scientists Are Investigating Its Massive Skull and Crushing Teeth to Decipher the Beast’s True Nature

For more than a century, paleontologists have been piecing together how the mysterious predator Andrewsarchus is related to other mammals, like the extinct “hell pigs” and “wolves with hooves”

Researchers are developing A.I.-based facial recognition tools to identify individual bears.

How Do Researchers Identify Individual Bears in the Wild? They Could Soon Do It Through A.I. Facial Recognition Technology

Such tools could help scientists track population sizes or recognize aggressive animals that have attacked humans

Chacma baboons (Papio ursinus) get jealous of their siblings' grooming sessions. 

Like Humans, Baboons Get Jealous of Their Siblings

A new study found that young baboons try to interrupt their mother when she is grooming a sibling

Bird flu devastated a colony of northern gannets, seabirds almost the size of albatrosses, on Bass Rock in Scotland. Researchers working with the birds are holding onto hope that the breeding population will slowly build the colony back.

After a Devastating Bird Flu Outbreak, Scotland’s Seabirds Are Slowly Recovering—and So Are the Scientists Who Witnessed Their Decline

The world’s largest colony of northern gannets was decimated by bird flu in 2022. Now, as their numbers climb again, researchers are collecting data to understand the virus’ lasting effects
