Patrick Walsh and Amy Pederson from the University of Edinburgh, UK, together with Erin Mccreless from the University of California, Santa cruz, noticed that the related wild white-footed mouse (Peromyscus leucopus)

whether the mice truly prefer being near the smelly stuff Their first finding was that, like sheep,

they could not distinguish between the droppings of parasitised and healthy mice. But the second finding was a complete surprise:

the mice were more likely to choose to spend their time in an enclosure containing faeces than in a clean one.

they preferred cotton previously used by other mice to unused cotton for nest-building. Perhaps most surprising the mice even preferred parasitised cotton balls to clean ones.

These preferences also applied to their foraging behaviour. The mice were no less likely to eat seeds that were found near faecal material oe

whether infected or not oe than to eat seeds that were clean. In a way, the mice were the opposite of the sheep.

Neither animal could distinguish parasitised from healthy droppings yet sheep responded by playing it safe,

while the mice took a gamble. The crucial question is why? At first glance, their actions might seem like a bad idea, given the high costs of becoming infected.

What is really interesting is domesticated that rodents, such as mice and rats bred for laboratory use

or for the pet trade, do avoid faeces. As wild reindeer and primates also avoid faeces,

Walsh and colleagues believe that for their wild mice, the presence of faeces from other mice at a potential nesting location

or near food suggests safety from predators. When the wrong move could land you between the teeth of a bigger animal,

from mice to brown bears, shake their bodies when wet oe the frequency being directly related to their size.

A mouse on the other hand has such a small frame, it needs to shake proportionally faster to generate the same forces to break the surface tension of water on its fur oe up to 33 times per second,

as well as adding a few of their own into the mix oe a colleague's pet rat called Coco, a pygmy hedgehog,

The first guinea pig was, well, the hedgehog. It didn't work. It looked spectacular surrounded by falling water droplets but ultimately, even in slow motion,

Then it was the turn of the rat and the dog oe both are found across much of the world and in wet and cold environments.

his team is using a similar approach to engineer mice with traits of naked mole rats. The odd-looking rodents live dozens of years instead of a handful like mice.

They are impervious to cancer and do not feel pain from acids. To endow ordinary lab mice with these traits Church will try to partially rewrite the genomes of mouse stem cells.

However, he admits that creating a passenger pigeon from the stem cells of an ordinary pigeon would involve a massive scale up of the same technologies.

For instance, a recent study found that making a chimeric rhesus monkey oe a process needed to resurrect a monkey species from frozen cells oe is much trickier than a mouse."

Dr Seralini concluded that rats which ate the GM maize had statistically significant signs of liver and kidney damage.

#Japanese scientists create 581 clones from the same mouse Scientists clone 581 mice from one mouse.

They have managed to push the technique to new limits by cloning 581 mice all from a single original cell.

The first was a genetically identical mouse produced in 1979. Shortly thereafter the first genetically identical cows

scientist have used SCNT to clone other mammals including cat, dog, deer, horse, mule, ox, rabbit and rat.

the authors of the current work were able to clone a mouse to the sixth generation but just barely.

For example, a series of cloned mice were shown to express an RNA molecule that inactivated one of the female s X chromosomes.

When the RNA molecule was removed cloning efficiency of the mice increased nearly ninefold. Based on previous work, the Japanese researchers sought to improve their cloning efficiency by using a chemical called trichostatin A that inhibits the powerful epigenetic protein histone deacetylase.

the inhibitor allowed them to produce 581 mice through 25 rounds of SCNT cloning. The mice were healthy

and were able to reproduce. What s more the cloning success rate did not decrease with each generation.

Without it, young mice face long-lasting consequences, including several signs of inflammatory bowel diseases (IBD).

Although the team only looked at mice, Kaetzel notes that several studies have found that breastfed babies are less likely to develop IBD later in life.

Mice and humans eventually make SIGA for themselves but in our earliest days of life,

When Rogier engineered mutant mice that couldn t produce SIGA in their milk, he found that their pups grew up with peculiar guts.

As a mouse grows up, its gut microbes interact with its own gut cells to create a sealed barrier that keeps foreign material out of the deeper intestinal tissue.

But if newborn mice can t get SIGA from their mothers, their intestinal barriers are porous

When you take them out of an adult mouse and culture them, you ll find no bacteria.

These early changes persisted into adulthood and left the mice permanently susceptible to inflammation, even if they could eventually make SIGA for themselves.

These mice had altered two sides of this triangle, says Kaetzel. They didn t get enough SIGA (a host factor),

It worked on rats anyway. But researchers say in humans coffee might enhance the sexual experience only among people who are not habitual users.

Since the 1950s when researchers cloned a frog scientists have cloned dozens of animal species including mice cats sheep pigs and cows.

With mice researchers were able to use thousands of eggs and conduct many experiments to work out these problems Lanza said.

In addition researchers can't simply apply what they've learned from cloning mice or cows to cloning people.

In mice this isn't a problem because the embryo that is ultimately created is able to make these proteins again.

One explanation in vogue in the early 1980s was that the mysterious circle patterns were produced accidentally by the especially vigorous sexual activity of horny hedgehogs.

They put six rats in a pen and monitored individual neurons while the rats explored.

The neurons they were watching lie in a part of the brain called the entorhinal cortex. It sits in the lower part of the brain near its intersection with the brain stem.

Â As a rat walked around the enclosure a neuron in the entorhinal cortex fired;

the rat walked a little more and the neuron fired again. When the team mapped out all the points in the enclosure that had lit up a particular neuron they found that these weren't just random signals:
