Scientists demonstrated that, contrary to what had been assumed for several years, colour variations among female macaques do not precisely indicate the time of ovulation. On the other hand, dominant female macaques, who usually have greater reproductive success, have darker hindquarters.
Researchers have found that a gene known as AEBP1 may play a central role in the development, severity and potential treatment of liver disease, according to a study by Temple University, the Geisinger Obesity Institute and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope. One of the study's major findings is that AEBP1 regulates the expression of a network of at least nine genes related to fibrosis: AKR1B10, CCDC80, DPT, EFEMP1, ITGBL1, LAMC3, MOXD1, SPP1, and STMN2.
A computational simulation suggests that insects may be capable of using the properties of light from the sky to determine their compass direction with an error of less than two degrees. Evripidis Gkanias of the University of Edinburgh, U.K., and colleagues present their findings in PLOS Computational Biology.
Spaying or neutering large-breed dogs can put them at a higher risk for obesity and, if done when the dog is young, nontraumatic orthopedic injuries, reports a new study based on data from the Morris Animal Foundation Golden Retriever Lifetime Study. The spay/neuter study was published today in the journal PLOS ONE.
Giving credence to the saying, 'While the cat's away, the mice will play,' a new study indicates that pumas and medium-sized carnivores lie low when they sense the presence of humans, which frees up the landscape for rodents to forage more brazenly.
University of Guelph researchers have become the first to access data on more than 19 million cats and have learned that most cats continue to put on weight as they age.
Feline hyperthyroidism is the most common endocrine-related disease of older cats, and its prevalence has skyrocketed since the first case was diagnosed in 1979. At the same time, new household flame retardants were introduced, and recently, scientists have suspected a link. Now, researchers reporting in ACS' Environmental Science & Technology have associated hyperthyroidism with another class of flame retardants, using silicone pet tags similar to the popular wristbands that many people wear for charitable causes.
Data from the Morris Animal Foundation Golden Retriever Lifetime Study shows that inbreeding depression, the result of breeding closely-related individuals, reduces litter sizes in purebred golden retrievers.
A sulphur-crested cockatoo named Snowball garnered YouTube fame and headlines a decade ago for his uncanny ability to dance to the beat of the Backstreet Boys. Now, researchers reporting in Current Biology on July 8, 2019 are back with new evidence that Snowball isn't limited in his dance moves. Despite a lack of dance training, new videos show that Snowball responds to music with diverse and spontaneous movements using various parts of his body.
Climbing the social ladder is a ruff business for dogs, new research shows.
