The story is about two mice named Sniff and Scurry, and two little men named Hem and Haw.
FORBES: Change Happens. Embrace It. Enjoy It. Look Forward To It.
Unlike the two mice, which run on AAs, the T650 has a rechargeable battery, which you can re-juice over USB.

The two mice, having prepared for this day, recognize the need to go find new cheese and they run off through the maze in search of new cheese.

The two species of mice were successively bred, and those hybrids built long, two-tunnel burrows like oilfield mice - showing that the behaviour is a "dominant" trait.
Logitech just announced two wireless mice and an external trackpad, all optimized to support gestures in Windows 8.

In a study published in the May issue of Nature Genetics, researchers at Princeton University disrupted the epigenetic imprints on several mice genes by crossing two related strains of mice.
Researchers put two groups of mice on the same high-calorie diet.
However, the researchers managed to produce two healthy baby mice from heated sperm, and genetic analysis suggested that no damage to the DNA had been suffered.
Besides, the two researchers say, mice and rats are especially susceptible to cancer.
The researchers exposed both groups of mice to two types of stress.
They infected mice with two bacteria that are both common in lung infections - Pseudomonas aeruginosa and Staphylococcus aureus - and sampled their breath after 24 hours.
They charted changes in the genetic activity in two groups of ageing mice, one group on a standard diet and the other whose diets have been cut to 76% of the standard diet.
But Dr Craig Venter, the president of Celera, said in a newspaper interview on Friday that his company had already sequenced the genomes of three different strains of mice, two of them to 90% completion, and was perplexed by the new public initiative.
The mice the two independent labs used were several generations distant from the original strain or grown from preserved embryos, and in that interval, any number of changes could have happened in gene sequences or to affect how the animal uses the gene.
The Buck Institute's Dr. Kennedy led a team earlier this year that found that another form of rapamycin was effective in increasing the life spans and improving symptoms in mice with two different diseases caused by other mutations in the progeria-connected Lamin A gene.
They found that two of these versions protected mice against the toxin.
The best experimental model is the mouse, but infected mice may take two years to show signs and symptoms of prion diseases.
In an experiment at Johns Hopkins, in 2010, mice were confronted with two levers, one that dispensed a treat after being pressed only once, another that required fifteen presses before it released a similar snack.
The mice were split into two groups.

Mice with a mixture of the two genes were found to be protected against S. typhi infection.
To make absolutely certain, the team used two different strains of parasite in different groups of mice.
To figure out why, they employed a more systematic approach, activating two specific genes called NOTCH and AKT in the mice.
But in September, two independent groups reported that the same strain of mice, bred from animals furnished by the Brose lab, do not show any social deficits.
We also prefer our mice to have an extra shortcut button or two, so the Whirl certainly disappoints to that end.

And as we become more and more accustomed gestures, mice, and the single-point, two-dimensional actions they demand, make less and less sense.
These showed that unless the two tones were sufficiently separated in time, only one electrical signal, rather than two, was generated by the brains of the affected mice in response.
The studies, one on mice and one on people, have identified two hormones that seem to fine-tune the perception of sweetness, and thus regulate the intake of sugar independently of the previously known mechanism of satiation that is located in the brain.
ECONOMIST: Hormones influence how sensitive taste buds are to sugar
Those who received bacteria from the bypass mice, lost a significant amount of weight in two weeks but the others saw no change.
BBC: Bacteria find 'key to treating obesity without surgery'
We can always replace equipment, we can always replace reagents, we can even replace mice, but replacing an experiment that took you two years to complete is really tedious.
