New glass-ceramic emits light when under mechanical stress
Researchers have created a new glass-ceramic that emits light in response to mechanical stress, a property known as mechanoluminescence. With further development, the new material could be used to create a light source that is switched on by mechanic.....»»
Western media outlets are trying to fix their coverage of Africa. Is it time African media did the same?
Quick question: what do these titles have in common? A Dark Continent Seeking Light; Sure, Ebola is Bad. Africa has Worse, or; Magic and Cannibalism in the African Jungle. You guessed it—they're all about Africa. But the most correct answer is they.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
