When two mice breed, the offspring is a mouse. When that offspring breeds, its offspring is a mouse. When that offspring breeds... And the process continues. Point mutations do not change this fact in any significant way over the short haul. Carl Sagan, in "The Dragons of Eden," put ...
Often, the mechanism is not even conserved between closely related taxa. For example, in mammals such as mouse, cow or rhesus monkey, the paternal mtDNA undergoes a reduction in the sperm but is fully degraded only later during early embryogenesis (i.e. after initially biparental...
However, in rods, the amplitude of the single-photon response substantially exceeds the cellular noise level and is reliably detectable above that noise. How has this been beneficial to the organism? By permitting the evolution of retinal circuitry that can process these single-photon events, ...
Mice have long been used as models for human diseases. From the modeling experiments using human protein sequences, along with the high conservation of this protein structure across species, the precise molecule that caused infertility in mice likely functions the same way in humans. "What is rea...

theAPCminmouse model, which is used for studying familiar predisposition to colon cancer, has increased incidence of colon polyps, which are considered a pre-malignant stage of colon cancer. However, the number of polyps varies strongly depending on the background strain that is used. By performi...

The obesity related mitochondrial experimental changes in mouse oocytes can be prevented and rescued with CoQ10. Some of the underlying changes were lower levels of ATP and citrate [194]. In pregnant Holstein heifers, selenium supplementation can increase progesterone levels [195]. A similar effect...
In the present study, we developed an isoform-specific real-time PCR method to selectively measure the mRNA expression of mouse, human and rat α-SMA and ß-actin as well. Moreover, we demonstrated the significance of the inaccuracy caused by the use of non-specific α-SMA or ß-actin...
The simplified graphical interface of the Apple II (in comparison to other products, many of which didn't even have a screen) and the creation of the first effective mouse (designed in conjunction with product-design firm IDEO) are ex- amples of how great design made these new technologies...
