Fearless Mouse and Glow in the Dark Cats

TOKYO - The age-old animosity between cats and mice could be a thing of the past with genetically modified mice that Japanese scientists say show no fear and shed new light on mammal behavior.

Scientists at Tokyo University say they have used genetic engineering to successfully switch off a mouse's instinct to cower at the smell or presence of cats — showing that fear is genetically hardwired and not learned through experience, as commonly believed.

SEOUL (AFP) - South Korean scientists have cloned cats by manipulating a fluorescent protein gene, a procedure which could help develop treatments for human genetic diseases, officials said Wednesday.

In a side-effect, the cloned cats glow in the dark when exposed to ultraviolet beams.
