A recent study on Border Collies confirms older dog can be taught new tricks, although younger individuals learn faster.
A new study suggests nurse sharks have the lowest metabolic rate of any shark species. This means they don't have as great an impact on their ecosystems as large predators do.
A new study from McMaster University challenged Charles Darwin's long-standing theory of female choice. Rather than females being drawn to males that have the most vibrant tail feathers or best dance moves, researchers suggest that, once aroused, courtship displays have no bearing on a female's mate preference.
Reed warblers have set up a "neighborhood watch" to protect their nests from invasive cuckoos, who lay their eggs in local nests for others to raise. When reed warblers spot a cuckoo, they mob it and emit alarm calls that alert neighbors a cuckoo is at large and they should monitor their eggs closely. This has greatly benefited warblers, but cuckoo populations appear to be suffering.
When darkness falls, bats emerge from their cave dwellings to forage, relying on the echos of their own calls to locate prey. A new study suggests bats avoid noise overlap in large groups by increasing the volume, duration and repetition rate of their own unique signals.
For the first time ever Chinese scientists have created genetically modified monkeys with a human gene for autism. The primates displayed asocial behavior, including becoming stressed when looked in the eye. Researchers from the Institute of Neuroscience in Shanghai hope their findings help treat the disorder in humans.
A lost sloth recently found itself stranded in the middle of a busy road in Ecuador, unable to make it to the other side. Transport officials quickly came to the animal's rescue, and after being checked out by a veterinarian, the sloth has been returned to the wild.
A recent study of carnivorous animals foiund that those with large brains (relative to their body size) are better at solving problems than smaller-bodied individuals. Of the 140 animals tested, bears were the most successful at retrieving their favorite snacks from inside a secured metal box.
Not all lizards are able to change the color of their skin to blend in with their surroundings. Therefore Aegean wall lizards, for example, camouflage by choosing rocks that best match the color of their backs, thus ensuring they are able to remain hidden from avian predators.
Sea slugs have colorful patterns to ward off predators -- but when that doesn't work they defend themselves using toxic chemicals they gather from their environment.
Researchers found that prairie voles show empathy by grooming or consoling another individual that appears to be distressed. This could be a major breakthrough for better understanding of psychiatric disorders in humans, including autism spectrum disorder (ASD) and schizophrenia.
The Basking Shark Satellite Tagging Project opened up a new finding: The Sea of the Hebrides off the west coast of Scotland may be a hot spot for basking sharks feeding, breeding and migrating in the summer.
Humans, of course, do Zumba and Cross-Fit and many other things to stay fit. However, researchers investigating animals' active lifestyles are wondering whether they too work out to maintain perfect figures.
Snowshoe hares typically shed their brown summer coats to blend in with the snowy scenery of the winter. However, when there is no snow, these mismatched animals have no place to hide and increase their chances of being spotted by a predator.
In the face of a challenge, practice makes perfect for grey squirrels. Researchers from the University of Exeter found that squirrels were able to quickly learn which lever to either push or pull to release food from a closed box when they remained persistent.
