Quantum mechanics drives photosynthesis - you lost me at quantum

-Everyone has heard of photosynthesis - a process used by green plants to convert sunlight into electrochemical energy at an efficiency of nearly 100%.
-Although the overall pathway and major players are known for this process, the nitty-gritty details have eluded scientists, until now.
-Physical chemists at UC Berkeley observed 'entanglement' (a distinctive property of quantum mechanical systems) in the light harvesting complex in plants.
-Importance: huge step towards developing (a) artificial photosynthesis systems as renewable, non-polluting electrical energy sources and (b) quantum-based technologies e.g. quantum computers which are potentially thousands of times faster than conventional computers.

Want to get smarter? Then take a nap

• A midday nap could refresh the mind and actually make you smarter.
• A simple experiment showed that young adults who took a nap in the early afternoon after a rigorous study session improved their learning capacity in the early evening during another study sesh compared to those who didn’t nap and got worse at learning.
• "It's as though the e-mail inbox in your hippocampus is full and, until you sleep and clear out those fact emails, you're not going to receive any more mail. It's just going to bounce until you sleep and move it into another folder," said Matthew Walker, assistant professor of psychology and lead investigator at UC Berkeley.
• Many would argue that napping for such a short period of time doesn’t actually help because you never enter REM sleep.
• However, this study backs the notion that Stage 2 non-REM sleep, which occurs after deep sleep (non-REM) but before the dream state (REM), is vital for memory capacity.
• After all, we spend 50% of the night in this Stage 2 transition stage so it makes perfect sense that it plays a crucial role in a healthy mindset.
