These glowing kittens may hold an important clue in the fight against AIDS in felines... and people.
Researchers with the Mayo Clinic are modifying genes in cats and say they're quite impressed with the results.
They say they inserted genes from a monkey into cats' eggs before fertilization. The genes are known to block FIV infections, similar to HIV in humans. The team also placed a jellyfish gene in the cats for tracking purposes. That's what makes the resulting kittens glow green.
Researchers say early tests show these kittens' modified cells kept FIV infections from spreading.
