Cilia are thin, eyelash-like extensions on the surface of cells. They perform a wide variety of functions, acting as mechanosensors or chemosensors, and play a crucial role in many signaling pathways......»»
Examining the effect of climate change media reports on stock returns
Climate change is the defining crisis of the 21st century. United Nations Secretary-General Antonio Guterres called it a "crisis multiplier", while renowned naturalist Sir David Attenborough described climate change as "the biggest threat to security.....»»
New experimental research measures the speed of molecular charge migration for the first time
To discover how light interacts with molecules, the first step is to follow electron dynamics, which evolve at the attosecond timescale. The dynamics of this first step have been called charge migration (CM). CM plays a fundamental role in chemical r.....»»
