A recent study found that wolves and dogs can learn where to find food by observing a human or dog demonstrator. This suggests that the ability to learn from others was already present in wolf ancestors, which prehistoric humans could then build on. The researchers' findings provide new insights into the domestication of dogs.
Scientists have found a protein called UCP1 that burns energy and produces heat in the body. Activating this protein using fatty acids may lead to a new way of triggering fat burning and could potentially help with weight loss.
A study found that scent marking increases males' mating and reproductive success, as females prefer to mate with males who deposit more conspicuous scent marks. However, surprisingly, female mice tend to socialize with lower-marking males, suggesting a complex relationship between scent marking and social behavior.
Researchers found that fatter dormice increase metabolic rate more frequently and spend more time at normal body temperature during hibernation, minimizing negative effects. This strategy enables dormice to maximize total hibernation time while maximizing survival chances.

However, gentle drafts can significantly affect temperature readings, rendering diagnoses unreliable. To achieve accurate results, veterinarians should perform thermography in draft-free surroundings.
In a study of cichlids, researchers found that parents adopt fry from other families to protect against predators, while also delivering their own young for adoption. This strategy ensures the survival of at least some offspring in a species highly predated.

A whole-genome sequence of the fruit fly Drosophila mauritiana has been completed, revealing high genetic diversity across its chromosomes. The researchers identified two large regions with conserved sequences and propose that these may be the result of intragenomic conflict, potentially acting as 'speciation genes'.
Researchers found that male toads storing sperm during the breeding season produced sperm with higher motility than those kept under natural conditions without females. Frequent mating also appeared to slow down sperm senescence, a process affecting sperm quality with age.
Researchers studied zebrafish mating behavior and found that males change color during courtship, while females do not, supporting the hypothesis that body coloration plays a role in zebrafish courtship. The study also revealed differences in color properties between wild-derived and domesticated strains of zebrafish.
Swans are found to have more common hip joint problems than previously believed, with CT scans revealing lesions in all five examined birds. The injuries likely occur during landing on hard surfaces, and the study suggests that computerized tomography is a better diagnostic tool for avian patients.
