The emergence of exotic diseases such as Ebola and SARS (severe acute respiratory syndrome) in people has prompted intensive research into new drug treatments, and this is indirectly bringing benefit to cats.
Mucosal melanoma arises in non-skin locations such as sinuses, nasal passages and mouth. The research team sequenced the genomes of mucosal melanoma tumours from 46 humans, 65 dogs and 28 horses and discovered a handful of genes that were commonly mutated in all species. These genetic similarities point to the drivers of the disease -- key information that will lead to using biologically relevant drug targets.
Male butterflies have genes which give them a sexual preference for a partner with a similar appearance to themselves, according to new research. In a study publishing Feb. 7 in the open-access journal PLOS Biology, a team of academics from the University of Cambridge, in collaboration with the Smithsonian Tropical Research Institute in Panama, observed the courtship rituals and sequenced the DNA from nearly 300 butterflies to find out how much of the genome was responsible for their mating behavior.
The cleaner wrasse fish (Labroides dimidiatus), responds to its reflection and attempts to remove marks on its body during the mirror test -- a method considered the gold standard for determining self-awareness in animals. The finding, publishing on Feb. 7 in the open-access journal PLOS Biology, suggests that fish might possess far higher cognitive powers than previously thought, and ignites a high-stakes debate over how we assess the intelligence of animals that are so unlike ourselves.
Background noise is usually regarded as a nuisance that masks important sounds. But noise can convey information about important environmental conditions and allow animals to make informed decisions. When bat researchers played rain sounds for two different species of bats, both species chose to delay emergence from their roosts.
Syrian hamsters are golden-haired rodents often kept as house pets. Cold and darkness can cause the animals to hibernate for 3-4 days at a time, interspersed with short periods of activity. Surprisingly, the hibernation spurts of these cute, furry creatures could hold clues to better treatments for Alzheimer's disease (AD), according to a recent study in ACS' Journal of Proteome Research.
Sand fiddler crabs that reside in a burrow usually prevail if challenged by another, intruding crab, provided their claw pinching strength is similar to that of the competing crab, a study suggests.
A gene defect identified in Karelian Bear Dogs causes a severe bone disease. A gene test has been developed for diagnostic and breeding purposes.
Larger dogs have better short-term memory and self-control than smaller breeds, according to research led by the Arizona Canine Cognition Center at the University of Arizona.
In a first-of-its-kind study, scientists at the University of Missouri have helped advance a patient-specific, precision medicine treatment for bone cancer in dogs. By creating a vaccine from a dog's own tumor, scientists worked with ELIAS Animal Health to target specific cancer cells and avoid the toxic side effects of chemotherapy, while also opening the door for future human clinical trials.
