'Lying mirror' uses structured surfaces to conceal optical information
Mirrors normally reveal what is placed in front of them, even when their curvature distorts a reflection. Researchers at the University of California, Los Angeles (UCLA) have introduced a different optical concept: a "lying mirror" that hides information carried by an input image
Scientists twist crystal layers and reshape matter from within
Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up. Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a
Could understanding leaf surfaces lead to new ways to prevent crop disease?
Fungal diseases that affect grain crops can be devastating to global agriculture and food security. Fungicides are the most common preventive measure, but as fungal diseases become more prevalent, the pathogens become increasingly resilient.
