mouse : any of numerous small rodents (as of the genus Mus) with pointed snout, rather small ears, elongated body, and slender tail — Webster

Mouse, plural mice, is a small rodent characteristically having a pointed snout, small rounded ears, a body-length scaly tail and a high breeding rate. The best known mouse species is the common house mouse (Mus musculus). It is also a popular pet. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter.
Species of mice are mostly found in Rodentia, and are present throughout the order. Typical mice are found in the genus Mus.
Mice are typically distinguished from rats by their size. Generally, when someone discovers a smaller muroid rodent, its common name includes the term mouse, while if it is larger, the name includes the term rat. Common terms rat and mouse are not taxonomically specific. Scientifically, the term mouse is not confined to members of Mus for example, the deer mouse.
Domestic mice sold as pets often differ substantially in size from the common house mouse. This is attributable both to breeding and to different conditions in the wild. The best-known strain, the white lab mouse, has more uniform traits that are appropriate to its use in research. — Wikipedia
Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus Rattus. Other rat genera include Neotoma (pack rats), Bandicota (bandicoot rats) and Dipodomys (kangaroo rats).

Chromosomal speciation in wild house mice

A new look into the genomes of natural populations of the common house mice by a team of researchers suggests that large-scale chromosomal rearrangements play an important role in speciation.

In a new study, researchers have discovered how the protein PP2A can inhibit tumor growth in mice. The protein turns off an enzyme that stimulates cell growth, thus inhibiting the development of cancer.

As inevitable fellow travellers on the bodies of astronauts, spaceships, or equipment, terrestrial microorganisms will undoubtedly come into contact with extraterrestrial environments. Researchers now describe how bacteria can survive on an 'extraterrestrial diet', which affected their pathogenic potential.
Cell reproduction dogma challenged
on May 22, 2020 at 6:51 pm
Meiosis is essential to sexual reproduction. For almost 15 years, it has been commonly held that retinoic acid, a molecule derived from vitamin A, triggers meiosis in mammalian germ cells. Yet new research demonstrates that meiosis in mice begins and proceeds normally even in the absence of retinoic acid. These findings set the stage for new research in the field of reproductive biology.

on May 21, 2020 at 3:26 pm
Researchers used a genetic database of more than 47,000 people in Estonia to identify a gene linked to thinness that may play a role in resisting weight gain in metabolically healthy thin people. They show that knocking out this gene results in thinner flies and mice and find that expression of it in the brain may be involved in regulating energy expenditure.

The microbes that inhabit our bodies are influenced by what we eat, drink, breathe and absorb through our skin, and most of us are chronically exposed to natural and human-made environmental contaminants. Scientists review the research linking dozens of environmental chemicals to changes in the gut microbiome and associated health challenges.

Cat parasite reduces general anxiety in infected...
on January 14, 2020 at 3:00 pm
The cat parasite Toxoplasma gondii is known to cause infected rodents to lose their fear of feline predators, which makes the mice easier to catch. Predators then spread the parasites through their feces. But this so-called fatal feline attraction theory is flawed, suggests a study publishing January 14 in the journal Cell Reports. Rather than exhibiting a loss of feline-specific fear, infected rodents actually show a decrease in general anxiety and reduced aversion to a wide range of threats.

For most humans, life on these jagged islands off the coast of San Francisco would be a nightmare: Waves lash the shore with treacherous force, the stench of guano fills the air, and the screech of seagulls is so loud that resident scientists wear earplugs to bed.
Two new species of 'tweezer-beaked hopping rats'...
on June 6, 2019 at 2:00 pm
Just about everybody loves peanut butter. We put it on sandwiches and in candy, we use it to trick our dogs into taking their heartworm pills, and, when we have to, we bait mouse traps with it. But, as scientists learned when trapping rodents in the mountains of the Philippines, peanut butter isn't for everyone. A highly distinctive (weird-looking) group of rodents sometimes called "tweezer-beaked hopping rats" don't care for peanut butter, but love earthworms. Armed with this knowledge (and […]

on March 25, 2019 at 12:20 pm
A house proud mouse, considerately tidying up the workbench of the shed in which it lives, has been captured on video and shared online. The mouse pops out of a box, picks up some screws, nail clippers and a metal chain and carries them back into the box. It's tempting to think the mouse is cleaning up its home in the same way that a human would. Of course, in biology, things are rarely that simple.
