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.

Saw this somewhere else and felt the need to post it cause no one else ever really tells you this stuff
My mom never really noticed. She noticed when she was breast feeding my little brother and blood started coming out instead of milk.
My mom said she felt and saw a little lump in the shower. She was lucky enough she found it at stage 2
My mom had a mammogram. The radiologist thought the spots were just regular calcium deposits.
Turns out it was triple negative breast cancer that had spread to her lymph nods. Mastectomy, radiation and chemo saved her life.
This could SAVE a life.
