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

Bird flu’s surprising heat tolerance has...
on November 28, 2025 at 12:37 pm
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.

The first center for dispersing sterile screwworm flies from U.S. soil in decades opened Monday in Texas, part of a larger effort to keep the flesh-eating parasite they spawn from crossing the Mexican border and wreaking havoc on the American cattle industry.

Paleontologists at the Canadian Museum of Nature have recently been studying the skeletal remains of a rhinoceros. This might not sound remarkable at first, but what makes these remains fascinating is that they were found Devon Island in the Canadian Arctic.
Moving closer to 'true' equine IVF for clinical...

Three years ago, Penn Vet researchers reported a major breakthrough in equine assisted reproduction. Katrin Hinrichs, Harry Werner Endowed Professor of Equine Medicine, and colleagues developed a technique that would allow successful conventional in vitro fertilization (IVF) with horses. In conventional IVF, the sperm does its job of finding and fertilizing a mare's egg, or an oocyte, in a Petri dish. Developing a method to motivate stallion sperm to do this—let alone do it consistently—had […]
