Bigger Brains Could Increase Cancer Risk

A new study reports bigger brain size could mean an increased risk of developing brain cancer. The reason, researchers say, is simple. Bigger brains have more brain cells, and thus a greater potential for cell mutations that lead to cancer.

Small Brained Female Guppies Are Not Drawn to Attractive Males

A new study reports female guppies with smaller brain mass can distinguish between attractive males, but do not find them more appealing or choose to mate with them over less attractive guppies. Researchers say the study sheds new light of the link between mate preference and cognitive ability.
