Pies: It is a myth that dogs are color blind

The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of wolves. Also called the domestic dog, it was selectively bred during the Late Pleistocene by hunter-gatherers. Dogs and the modern gray wolf share a common ancestor. Dogs were the first species to be domesticated over 14,000 years ago, before the development of agriculture, though genetic studies suggest the domestication process may have begun over 25,000 years ago. Due to their long association with humans, dogs have gained the ability to thrive on a starch-rich diet that would be inadequate for other canids. Dogs have been bred for specific behaviors, sensory abilities, and physical traits. Dog breeds va…

Gene therapy for color blindness is an experimental gene therapy of the human retina aiming to grant typical trichromatic color vision to individuals with congenital color blindness by introducing typical alleles for opsin genes. Animal testing for gene therapy began in 2007 with a 2009 breakthrough in squirrel monkeys suggesting an imminent gene therapy in humans. While the research into gene therapy for red-green colorblindness has lagged since then, successful human trials are ongoing for achromatopsia. Congenital color vision deficiency affects upwards of 200 million people in the world, which represents a large demand for this gene therapy.

Hating Women: A Constitution of Hate in Plain Sight.. In April 2023, the U.K. government announced that misogyny would not be categorized as a hate crime stating that this "may prove more harmful than helpful." This article argues that before and beyond hate crime, misogyny, understood as the hatred of women (from the Greek misein [hate] gynae [women]), is the foundational logic of our legal, social, and political order in the west. This constitution of hate relies on the active dehumanization, exploitation, and ownership of women's bodies by the institution of white men through making women the object of the "colonization of the everyday." This exhausting hatred is enacted through repetiti…

Horse vision through two lenses: Tinbergen's Four Questions and the Five Domains.. To improve human-horse interactions and reduce the risk of injury, it is essential to adopt an equi-centric perspective that prioritizes how horses perceive their environment. This review focuses on the equine visual system, both because it is the most studied of the horse's senses and because misunderstandings about how horses see can lead to unsafe or unsustainable handling. By applying two complementary frameworks, namely Tinbergen's Four Questions and the Five Domains model, we examine equine vision from both a biological and a welfare-oriented perspective. We explore the anatomical and functional feature…

In Greek mythology, Actaeon (; Ancient Greek: Ἀκταίων Aktaiōn) was the son of the priestly herdsman Aristaeus in Boeotia, and a famous Theban hero. Through his mother Autonoë he was a member of the ruling House of Cadmus. Like Achilles in a later generation, he was trained by the centaur Chiron. He succumbed to the fatal wrath of Artemis (later his myth became attached to tales of Artemis' Roman counterpart Diana), but the surviving details of his transgression vary: "the only certainty is in what Aktaion suffered, his pathos, and what Artemis did: the hunter became the hunted; he was transformed into a stag, and his raging hounds, struck with a 'wolf's frenzy' (Lyssa), tore him apart as th…

Color vision (CV), a feature of visual perception, is an ability to perceive differences between light composed of different frequencies independently of light intensity. Color perception is a part of the larger visual system and is mediated by a complex process between neurons that begins with differential stimulation of different types of photoreceptors by light entering the eye. Those photoreceptors then emit outputs that are propagated through many layers of neurons ultimately leading to higher cognitive functions in the brain. Color vision is found in many animals and is mediated by similar underlying mechanisms with common types of biological molecules and a complex history of the evo…
