New streetlamps could improve your view of the stars. A new paper published in the journal Optics Express describes a system for focusing light from streetlamps directly on the area required, with almost no light leakage horizontally or vertically. Conventional street lamps scatter up to 20% of their energy away from where it is required, not only wasting power but also leading to light pollution which obscures your view of the night sky. The proposed LED lamp uses a lens to limit where the light is projected, with a reflecting cavity to recyle light that would otherwise be wasted. The team thinks the system would use between 10 to 50% less power to illuminate a section of road than current LED streetlamps, which are already more efficient than regular lamps. A prototype is being developed and is hoped to be completed this October.

I’m pretty sure that when Death comes for him, Christopher Lee will be waiting with a knife, and I’m not betting on Death in that fight. Didn’t you read what that said? He is Death.   Not only did Christopher Lee tell Peter Jackson he didn’t have to imagine the sound of being stabbed, he worked with the sound designers to make it as realistic as possible from his own memory.
