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

  • The limits of vision: Seeing shadows in the dark
    on May 23, 2022 at 3:54 pm

    A specific retinal pathway enables mice to detect incredibly dim shadows -- nearly reaching the limit of what's physically possible. The same circuit is in human eyes, which might enable researchers to probe visual diseases at unprecedented resolution.

  • Dietary cholesterol worsens inflammation,...
    on May 19, 2022 at 8:48 pm

    New research suggests high levels of dietary cholesterol make mice sicker when infected with influenza. This study links cholesterol in the diet with exacerbation of a viral infection.

  • Repurposed antibiotic may be an effective...
    on May 19, 2022 at 6:10 pm

    Repurposed drugs may have a speedier path to clinical use because they have already been shown to be safe in people. A new study suggests clofoctol may be an effective treatment for SARS-CoV-2 infections in mice.

  • how one of the X chromosomes in female embryonic...
    on May 19, 2022 at 3:53 pm

    In most mammals, females have two X chromosomes and males have one X and one Y chromosome in each of their cells. To avoid a double dose of X-linked genes in females, one of the Xs is silenced early in the developmental process. This silencing is critical, yet how it happens has been relatively mysterious. Two new studies reveal more about this silencing process and insights that could improve stem cell research.

    on May 17, 2022 at 5:07 pm

    Scientists saw for the first time hallmarks of concussions and other head trauma in the brains of deceased headbutting animals -- muskoxen and bighorn sheep. The results may contradict the commonly-held belief that ramming animals do not suffer brain injuries and support the notion that studies on animals with brains evolutionarily similar to those of humans may help researchers understand and reduce traumatic brain injuries.

    on May 16, 2022 at 2:46 pm

    New gene-editing techniques are shedding light on how hormones impact social behavior in animals and possibly, humans.

  • Microbes help orchestrate how the gut uses its...
    on May 13, 2022 at 4:33 pm

    The microbes that help break down food actually tell the gut how to do its job better, according to a new study in mice. The researchers said it appears that the microbes are able to influence which of the gut's genes are being called into action, and in turn, that interaction might lead to a remodeling of the epithelial cells lining the gut so that they match the diet.

    on May 13, 2022 at 3:32 pm

    Patients prescribed antibiotics in hospital are more likely to get fungal infections because of disruption to the immune system in the gut, according to a new study.

    on May 13, 2022 at 2:35 pm

    A single hormone appears to coordinate the lifespan extension produced by a low-protein diet. Low-protein diets produce beneficial metabolic effects in aged mice, improving metabolic health, reducing frailty, and extending lifespan. These beneficial effects were also apparent when protein intake was reduced in middle-aged mice, even protecting against the detriments of obesity. Importantly, these beneficial effects were lost in mice that lacked FGF21, suggesting that its action in the brain is […]

    on May 12, 2022 at 6:43 pm

    Researchers have equipped gut bacteria with data logger functionality as a way of monitoring which genes are active in the bacteria. These microorganisms could one day offer a noninvasive means of diagnosing disease or assessing the impact of a diet on health. - latest science and technology news stories internet news portal provides the latest news on science including: Physics, Nanotechnology, Life Sciences, Space Science, Earth Science, Environment, Health and Medicine.

    on May 11, 2022 at 9:00 am

    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 […]

    on May 3, 2022 at 4:42 pm

    New ancient DNA analysis has shed light on how the black rat, blamed for spreading Black Death, dispersed across Europe—revealing that the rodent colonized the continent on two occasions in the Roman and Medieval periods.

    As I write this article, a furry blur of a rodent has just scampered across the room and under the couch. It's autumn in Australia and, as air temperatures plunge outside, rodents start seeking the warmth and plentiful food inside our houses.

    on November 30, 2021 at 12:27 pm

    It's no secret that jet lag and night-shift work can wreak havoc on the way our body's internal clock syncs up our daily wake-sleep cycle, known as circadian rhythm, but now researchers say they are a step closer to understanding how the brain creates behavioral rhythms optimized for diurnal, rather than nocturnal, life.

    on November 26, 2021 at 4:59 pm

    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.

    on November 22, 2021 at 3:00 pm

    Monarch butterflies and their close relatives thrive on poisonous milkweed, thanks to genetic mutations that block the effects of the plant's toxins while allowing the poisons to accumulate in the caterpillar or adult insects as deterrents to hungry predators.

    In inland Australia, rabbits have taken a severe toll on native wildlife since they were introduced in 1859. They may be small, but today rabbits are a key threat to 322 species of Australia's at-risk plants and animals—more than twice the number of species threatened by cats or foxes.
