Molecular markers identify cell types in the testes of cat species
A science team at the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW), Berlin, and at the University of Texas at San Antonio, USA, has now identified molecular markers for the most important cell types in the testes of domestic cats and endangered cat species. This is the prerequisite to generate male germ cells in the test tube. The research project is funded by an Einstein Junior Fellowship at the Humboldt University of Berlin and by the National Institutes of Health, USA. These findings have been published in the scientific journal "Theriogenology Wild".
Networks in the dog brain
A study on canine brain networks reveals that during mammalian brain evolution, the role of the cingulate cortex, a bilateral structure located deep in the cerebral cortex, was partly taken over by the lateral frontal lobes, which control problem-solving, task-switching, and goal-directed behavior. The study relies on a new canine resting state fMRI brain atlas, which can aid in the analysis of diseases characterized by dysfunctional integration and communication among brain areas.
Breed, age and puppyhood socialization linked to canine personality
While the breed of the dog is the most important factor related to personality, other relevant elements include age and the social environment. According to researchers from the University of Helsinki, both the breeder and the dog owner have an important role in the development of canine personality.
Genetics as conservation tool for endangered chimpanzees
The western chimpanzees of Guinea are threatened by mining activities. Using a novel genetic approach, UZH researchers and an international team have collected information on population size and community structure of the endangered species. These data provide an important baseline to assess the impact of mining.
Why are we avoiding taking our breaks?
To conduct the study, researchers asked 107 employees about their reasons for taking a break and not taking one. They then surveyed another 287 employees twice daily over five days about their sleep quality, fatigue, performance concerns, workload, and the number of breaks they take each day.
There's something about Jaymee Gencher
Currently a Ross University School of Veterinary Medicine student doing her clinical year at Tufts Cummings School of Veterinary Medicine, Jaymee knows that in order to succeed at your goals, the first step is believing in yourself. From solo traveling to moving (to not one, but two!) different countries during vet school, she is embracing her infinite potential. Originally from Toronto, she has literally crossed borders to pursue her ultimate objective: a residency in either oncology or critical care.
