(PhysOrg.com) -- New research in the U.S. has discovered that fruit fly larvae have a series of photoreceptors covering the body that can detect light even when their primitive "eyes" are covered or removed.
(Phys.org) —People have long heard that carrots are good for their eyesight, and strong evidence exists that eating fish also provides health benefits.
