No-chemicals solar powered bug killer seeks Europe expansion
Scientists find how plants grow to escape shade
Mild mannered though they seem, plants are extremely competitive, especially when it comes to getting their fair share of sunlight. Whether a forest or a farm, where plants grow a battle wages for the sun's ...
How to prevent earthquake damage: make buildings invisible
New design for a metamaterial could be far more efficient at capturing sunlight than existing solar cells
Metamaterials are a new class of artificial substances with properties unlike anything found in the natural world. Some have been designed to act as invisibility cloaks; others as superlenses, antenna systems ...
