Horse Dictionary (Horses and Horse Information)

Encyclopedia

Horse is one of two extant subspecies of Equus ferus. It is an odd-toed ungulate mammal belonging to the taxonomic family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature, Eohippus, into the large, single-toed animal of today. Humans began domesticating horses around 4000 BC, and their domestication is believed to have been widespread by 3000 BC. Horses in the subspecies caballus are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated, such as the endangered Przewalski’s horse, a separate subspecies, and the only remaining true wild horse. — Wikipedia

Science

Mammalogy is the study of mammals – a class of vertebrates with characteristics such as homeothermic metabolism, fur, four-chambered hearts, and complex nervous systems. Mammalogy has also been known as “mastology,” “theriology,” and “therology.” The major branches of mammalogy include natural history, taxonomy and systematics, anatomy and physiology, ethology, ecology, and management. — Wikipedia

    on February 25, 2026 at 9:01 am

    Horses have a vocal trick no one fully understood until now. Scientists have discovered that when a horse whinnies, it produces two completely different sounds at the same time. One is a deep tone created by vibrating the vocal folds, similar to how humans sing. The other is a high-pitched whistle generated inside the larynx, something never before confirmed in a large mammal. This rare ability, known as biphonation, likely helps horses send multiple emotional signals in a single call.

    Researchers discovered why bird flu can survive temperatures that stop human flu in its tracks. A key gene, PB1, gives avian viruses the ability to replicate even at fever-level heat. Mice experiments confirmed that fever cripples human-origin flu but not avian strains, especially those with avian-like PB1. These findings highlight how gene swapping could fuel future pandemics.

    Coccolithophores, tiny planktonic architects of Earth’s climate, capture carbon, produce oxygen, and leave behind geological records that chronicle our planet’s history. European scientists are uniting to honor them with International Coccolithophore Day on October 10. Their global collaboration highlights groundbreaking research into how these microscopic organisms link ocean chemistry, climate regulation, and carbon storage. The initiative aims to raise awareness that even the smallest […]

    In the long battle to create an effective HIV vaccine, scientists have made a major leap forward. A new study shows that a series of vaccines can coax the immune system to produce powerful antibodies capable of blocking a wide range of HIV strains -- including those that are typically the hardest to stop.

    A quick heart trace taken during a warm-up trot could identify racehorses at risk of cardiac arrhythmias during high-intensity exercise, according to a new study led by the University of Surrey. The screening method analyzes short, routine electrocardiogram (ECG) recordings that could be used to help prevent cardiac events in otherwise healthy horses, where no obvious signs of arrhythmia have been detected.

    Bacteria are a major cause of infections and death in hospital settings, due—in part—to the rising incidence of antibiotic resistance. In the United States, antibiotic-resistant bacteria are involved in more than 2 million infections and cause 23,000 deaths annually. There's a growing need for new options that can both treat infections and limit resistance.

    Scientists from National Taiwan University (NTU) and Linkou Chang Gung Memorial Hospital (CGMH) have developed a precision-engineered nanoplatform to conquer glioblastoma (GBM), the most aggressive and deadly form of brain cancer. Treating glioblastoma is notoriously difficult due to its diffuse infiltration, the formidable blood-brain barrier (BBB), and a highly complex tumor microenvironment. A major component of this protective microenvironment are cancer-associated fibroblasts […]
