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

Encyclopædia Britannica

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).

Rats are typically distinguished from mice by their size. Generally, when someone discovers a large muroid rodent, its common name includes the term rat, while if it is smaller, its name includes the term mouse. The common terms rat and mouse are not taxonomically specific. — Wikipedia

  • Social support promotes rehab participation in...
    on October 3, 2022 at 5:27 pm

    A research finding in mice that the drug gabapentin improved rehab compliance after spinal cord injury led scientists to a related, unexpected discovery: Injured mice that didn't receive gabapentin and declined to exercise by themselves were willing to hop on the treadmill when presented with a group rehab option.

  • 'Mystery gene' matures the skeleton of the cell
    on September 30, 2022 at 12:40 am

    Scientists have managed to track down one of the 'mystery genes' -- the gene that ensures that the final form of the protein actin is created, a main component of our cell skeleton.

    on September 29, 2022 at 5:34 pm

    New research in animal models show it's possible to create a compound that hits the same exact target as psychedelic drugs hit -- the 5-HT2A serotonin receptors on the surface of specific neurons -- but does not cause the same psychedelic effects when given to mice.

  • New zika vaccine shows promise in animal models

    on September 27, 2022 at 6:43 pm

    Cycles of a diet that mimics fasting appear to reduce signs of Alzheimer's in mice genetically engineered to develop the illness, according to a new study. Short cycles of a low-calorie diet that replicates fasting appeared to reduce inflammation and delay cognitive decline in mouse models of Alzheimer's disease; initial data indicates diet's safety in Alzheimer's patients.

  • Disarming the immune system's lethal lung response
    on September 23, 2022 at 8:53 pm

    Neutrophils are the body's first line of defense against infection. But if too many attack for too long, they can damage the tissues they're meant to protect. In the lungs, this damage can lead to acute respiratory distress syndrome, the leading cause of death due to COVID-19. Researchers have found that using a drug to inhibit a protein called PTP1B can prevent lethal lung inflammation in mice. This discovery may lead to better treatments for severe inflammatory conditions like sepsis and […]

    Engineers have developed microscopic robots, called microrobots, that can swim around in the lungs, deliver medication and be used to clear up life-threatening cases of bacterial pneumonia. In mice, the microrobots safely eliminated pneumonia-causing bacteria in the lungs and resulted in 100% survival. By contrast, untreated mice all died within three days after infection.

    It is now possible to deliver therapeutics based on short interfering RNAs to hepatocytes; however, new delivery solutions are necessary to target additional organs. In a new report now published in Nature Biotechnology, a team of researchers including Kirk M. Brown, Jayaprakash K. Nair, and Maja M. Manas, led by Vasant Jadhav at Alnylam Pharmaceuticals Cambridge MA, U.S., discussed the safe conjugation of 2'-O-hexadecyl (C16) to small interfering RNAs (siRNAs) for potent and durable silencing […]

    A study led by scientists at the Universitat Autònoma de Barcelona (UAB) and University of Kent uncovers how the genome three-dimensional structure of male germ cells determines how genomes evolve over time. Published in Nature Communications and carried out in rodent species, the study shows that the distinctive events occurring during egg and sperm cell production have a different impact on genome evolution and opens new research paths into the genetic origin of genome structure in all […]

    A study published in Frontiers in Veterinary Science reveals the presence of murine coronavirus—the murine hepatitis virus or M-CoV—in mice of the Canary archipelago (Spain) that could have reached the islands by maritime transport from the European continent. This is the first ecoepidemiological study to examine the presence of coronaviruses that circulate in mice and rats of the natural and urban environment of the islands of La Palma, El Hierro, Tenerife and Lanzarote.
