A step towards quantum gravity

Solving Einstein’s equations by using quantities that apply across all space and time coordinates could enable physicists to eventually find their ‘white whale’: a quantum theory of gravity.

Concise synthesis of pleurotin

Chemists report a concise synthesis of pleurotin by way of the Diels-Alder reaction and a radical epimerization. Their late-stage intermediate intersects a milestone 1988 synthesis, reducing the total number of steps needed. The new method could yield …
