(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.
A new method of creating laser pulses, more than 1,000 times as powerful as those currently in existence, has been proposed by scientists in the UK and South Korea.
