A recent study conducted at Massachusetts General Hospital found that men expend effort to view attractive female faces, even when they're not part of a social stimulus. The research also shows that areas of the brain previously linked to rewards like food and money respond to facial beauty, but not to attractive male faces.
Researchers discovered that parasitic worms develop normally into adults when in contact with specific immune cells in their host's liver, producing fewer eggs if disconnected. This adaptation allows the worms to thrive by exploiting their host's immune response.
