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).

Primate brain size does not predict their...
on September 25, 2020 at 3:33 pm
A research team has systematically investigated the cognitive abilities of lemurs, which have relatively small brains compared to other primates. Conducting systematic tests with identical methods revealed that cognitive abilities of lemurs hardly differ from those of monkeys and great apes. Instead, this study revealed that the relationship between brain size and cognitive abilities cannot be generalized and it provides new insights into the evolution of primates.

A new study suggests that star-shaped brain cells known as astrocytes could be as important to the regulation of sleep as neurons. The study builds new momentum toward ultimately solving the mystery of why we sleep and how sleep works in the brain. The discovery may also set the stage for potential future treatment strategies for sleep disorders and neurological diseases and other conditions associated with troubled sleep.

Scientists are planning for Phase 1 human trials of a vaccine they developed by using CRISPR gene-editing technology to mutate the parasite that causes leishmaniasis, a skin disease common in tropical regions of the world and gaining ground in the United States.

During pregnancy in mice, the billions of bacteria and other microbes that live in a mother's intestines regulate key metabolites, small molecules that are important for healthy fetal brain development, biologists report. Scientists had not known until now whether the maternal gut microbiota influenced brain development during critical prenatal periods.
Gut microbiome plays important role in sleep...
on September 23, 2020 at 4:48 pm
Obstructive sleep apnea (OSA) affects more than one billion people worldwide. Evidence suggests OSA can alter the gut microbiome (GM) and may promote OSA-associated co-morbidities, including diabetes, hypertension and cognitive problems. Researchers have discovered how OSA-related sleep disturbances affect the gut microbiome in mice and how transplanting those gut bacteria into other mice can cause changes to sleep patterns in the recipient mice.
New mouse model of tau propagation
on September 23, 2020 at 4:46 pm
Accumulation of assembled tau protein in the central nervous system is characteristic of Alzheimer's disease and several other neurodegenerative diseases, called tauopathies. Researchers have now established a new mouse model of tau accumulation and propagation in brain. Single intracerebral injection of synthetic tau filaments induced by dextran sulphate into wild-type mice caused seeding of endogenous tau, followed by spreading to distinct areas in a time-dependent manner.

Scientists have found that the 'segmentation clock' -- a genetic network that governs the body pattern formation of embryos -- progresses more slowly in humans than in mice because the biochemical reactions are slower in human cells. The differences in the speeds of biochemical reactions may underlie differences between species in the tempo of development.
Could breadfruit be the next superfood?...
on September 17, 2020 at 4:28 pm
A fruit used for centuries in countries around the world is getting the nutritional thumbs-up from a team of researchers. Breadfruit, which grows in abundance in tropical and South Pacific countries, has long been a staple in the diet of many people. The fruit can be eaten when ripe, or it can be dried and ground up into a flour and repurposed into many types of meals.
New path to neuron regeneration after spinal cord...
on September 16, 2020 at 3:35 pm
The astrocytic glial cell has the unique ability to form scar tissue around damaged neurons. The presence of scar tissue is associated with inhibitory effects on the regrowth of mature neurons that are damaged by spinal cord injury. Recent evidence suggests, however, that these inhibitory effects are reversible, and in new work, scientists show that astrocytic glial cells can in fact play a major role in facilitating neuron repair.

Humans, like other animals, have the ability to constantly adapt to new situations. Researchers have utilized a mouse model to reveal which neurons in the brain are in command in guiding adaptive behavior. Their new study contributes to our understanding of decision-making processes in healthy and infirm people.

Maureen Murray, V03, director of Tufts Wildlife Clinic and clinical associate professor at Cummings School of Veterinary Medicine, has been studying rodenticide exposure in birds of prey for over a decade. Exposure to rodenticides occurs when people use these chemicals to kill unwanted pests. Mice and rats, or possibly other animals, eat the poison, and then the birds eat the poisoned prey.

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.
