An infrared signal thought to reveal how molecules in perovskite solar materials respond to light-generated charges can arise largely from the way light travels through the thin film itself, a new theoretical study shows. Jun Nishida, assistant professor at the Institute for Molecular Science (IMS), Japan, found that light-generated charges alter how infrared light is reflected and transmitted within the film layers, producing sharp features that resemble changes in molecular vibrations even when the vibrations themselves are unaltered.

Some regions may already be living in a 1.5°C warmer world

Regions worldwide may have already experienced around 90%–94% of the warming expected when the global average reaches 1.5°C above preindustrial levels, and 65%–76% of that expected at 2°C of warming. The findings, published in Nature Climate Change, suggest that regional warming

Male lizard 'perfumes' may be more about rivalry than seduction

Animals communicate in ways that are sometimes obvious to us and sometimes almost completely hidden. Bright colors, songs and courtship displays are easy to notice. Chemical signals are different: an animal can leave a message behind long after it has moved away.
