Researchers at the Department of Cell Biology, Physiology and Immunology at Universitat Autònoma de Barcelona (UAB) are the first to have cloned mice in Spain. Cloe, Cleo and Clona are three female brown-coloured mice and were born respectively on 12 May, 3 June and 10 June.

Two previously identified pathways associated with aging in mice are connected, say researchers at the Stanford University School of Medicine.

On December 9, 1968, Douglas Engelbart, the director of Stanford Research Institute's (SRI) Augmentation Research Center, took the stage and gave what has since become known as "the mother of all demos." A number of ideas in use today were first demonstrated that day, including including hypertext , object addressing and dynamic file linking, as well as video conferencing. But the idea that people most held onto, was the mouse.

When I wrote about Microsoft's new BlueTrack optical sensor system, introduced on Tuesday for their upcoming Explorer Mouse with BlueTrack Technology and Explorer Mini Mouse with BlueTrack Technology(whew, those are mouthfuls!), I said they definitely weren't gaming mice. Well, Microsoft had something in its pocket for Wednesday: their first wireless gaming mouse, and it will feature the BlueTrack system.

"Big things come in small packages," the saying goes, and it couldn't be more true when discussing the mouse. This little creature has become a crucial part of human history through its contributions in understanding human genetics and disease.

Mouse mothers-to-be have a remarkable way to protect their unborn pups. Because the smell of a strange male's urine can cause miscarriage and reactivate the ovulatory cycle, pregnant mice prevent the action of such olfactory stimuli by blocking their smell.

Scientists at the University of Liverpool have found that female mice avoid mating with inbred males by ‘sensing’ the diversity of a protein type in their urine.

Scientists at the University of Liverpool have discovered that mice rely on a special set of proteins to recognise each other. Previous study assumed that another set of genes that influence smell in vertebrates might be used by animals that identify each other through scent.

Three years ago, "ultraconserved elements" were discovered in the genomes of mice, rats, and humans. These are DNA sequences 200 base pairs in length or longer — some are over 700 base pairs long — showing 100-percent identity among the three species. They have been perfectly conserved since the last common ancestor of mice, rats, and humans, which lived some 85 million years ago.

For mice, carbon dioxide often means danger - too many animals breathing in too small a space or a hungry predator exhaling nearby. Mice have a way of detecting carbon dioxide, and new research from Rockefeller University shows that a special set of olfactory neurons is involved, a finding that may have implications for how predicted increases in atmospheric carbon dioxide may affect animal behavior.

Blocking a single protein with an experimental drug prevented and treated both type 2 diabetes and atherosclerosis in laboratory mice that had been fed unhealthy diets and were genetically predisposed to these common killers, according to an article published online at Nature on June 6, 2007.

Researchers at the Johns Hopkins School of Medicine and their colleagues have found that mice simply expressing a human light receptor in addition to their own can acquire new color vision, a sign that the brain can adapt far more rapidly to new sensory information than anticipated.
