cat : : a carnivorous mammal (Felis catus) long domesticated as a pet and for catching rats and mice — Webster
Cat (Felis catus, or Felis silvestris catus, literally “woodland cat”), often referred to as the domestic cat to distinguish from other felids and felines, is a small, typically furry, carnivorous mammal. It is often called house cat when kept as indoor pet or feral/feral domestic cat when wild. It is often valued by humans for companionship and for its ability to hunt vermin. There are more than seventy cat breeds recognized by various cat registries.
Cats are similar in anatomy to the other felids, with a strong flexible body, quick reflexes, sharp teeth and retractable claws adapted to killing small prey. Cat senses fit a crepuscular and predatory ecological niche. Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. They can see in near darkness. Like most other mammals, cats have poorer color vision and a better sense of smell than humans. Cats, despite being solitary hunters, are a social species, and cat communication includes the use of a variety of vocalizations (mewing, purring, trilling, hissing, growling and grunting) as well as cat pheromones and types of cat-specific body language. — Wikipedia

Neurotoxocarosis (NT) occurs in humans when larvae of the Toxocara roundworm migrate into the central nervous system. That infection is accompanied by a complex molecular signaling cascade, including changes to anti-inflammatory lipid molecules, researchers now report.
The dark giraffe, the new dark horse
on September 26, 2019 at 2:58 pm
Darker male giraffes have been found to be more solitary and less social than their lighter-colored counterparts, according to new research. A long-term study revealed that the color of male giraffes' spots more strongly relates to their patterns of social association, rather than their age, as previously thought.
What wolves' broken teeth reveal about their lives
on September 24, 2019 at 6:31 pm
An evolutionary biologist has spent more than three decades studying the skulls of many species of large carnivores -- including wolves, lions and tigers -- that lived from 50,000 years ago to the present. She reports today the answer to a puzzling question.
Cats are securely bonded to their people, too
on September 23, 2019 at 3:12 pm
Cats have a reputation for being aloof and independent. But a study of the way domestic cats respond to their caregivers suggests that their socio-cognitive abilities and the depth of their human attachments have been underestimated. The findings show that, much like children and dogs, pet cats form secure and insecure bonds with their human caretakers.

Despite huge advances in science over the past century, our understanding of nature is still far from complete. Not only have scientists failed to find the Holy Grail of physics—unifying the very large (general relativity) with the very small (quantum mechanics) – they still don't know what the vast majority of the universe is made up of. The sought after Theory of Everything continues to elude us. And there are other outstanding puzzles, too, such as how consciousness arises from […]

App endgame: Detect dyslexia earlier
on October 8, 2019 at 3:42 pm
Dyslexia makes reading a struggle for millions of people, but the learning disability is rarely diagnosed before age seven. Now, a team of educators and scientists led by UConn professors has made a game-like app that could help teachers identify younger kids at risk.
