Lab mice kept in cool cages grow tumors faster than those living in balmier conditions.

Mice living in cages with temperatures of about 30° Celsius had better control of tumor growth than rodents kept at about 22°, the mandated temperature for lab mice. When kept in warmer cages, the lab mice had more killer T cells active in the diseased tissue and fewer cells that suppressed the immune system, scientists report November 18 in the Proceedings of the National Academy of Sciences.
