Scientists have discovered a novel type of resonant nanocavity that serves as a 'jail for photons'. The cavity confines light in all three dimensions (3D) simultaneously by exploiting a surrounding photonic band gap crystal nanostructure as the 3D jail's bars. more

Dental and heart experts are set to publish joint recommendations for medical and oral health professionals and patients. more

Usually, soft-bodied species like spiders aren't fossilized in rock like animals with bones and teeth. More often, ancient spiders and insects are more likely to be discovered preserved... more
