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

Modified CRISPR-Cas9 gene editing scissors are enabling researchers to make alterations to the genetic material of single-cell organisms that are indistinguishable from natural mutations. This method is making it possible to develop a (harmless) experimental live vaccine for the widespread parasite Toxoplasma gondii.

Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process—and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in such a battle, not every part of a catalyst participates in the reaction. But what if one could convince the unengaged parts of a catalyst to get involved? Chemical reactions could occur faster or more efficiently.

When it comes to getting a three-dimensional look at cells in the human body, it is not much different than figuring out precisely where a firefly is in a field at night. We can tell which direction it is in, but it is challenging to know how far away it is.

A new study, involving the University of Cambridge and led by the Pirbright Institute, has identified key genetic changes in SARS-CoV-2—the virus that causes COVID-19—that may be responsible for the jump from bats to humans, and established which animals have cellular receptors that allow the virus to enter their cells most effectively.

Micro-CT scanning and digital reconstructions have been used to compare the skulls of the Tasmanian tiger (thylacine) and wolf across their early development and into adulthood, establishing that not only did the thylacine resemble the wolf as adults, but also as newborns and juveniles.
