Two plant species invent the same chemically complex and medically interesting substance

Researchers at the Max Planck Institute for Chemical Ecology elucidated the biosynthetic pathway of ipecacuanha alkaloids in two distantly related plant species. The study reveals that both species developed the same pathway independently, with a surprising twist: the first step does not involve an enzyme, but occurs spontaneously.

Low vs. High blood pressure avoidance in non-cardiac surgery: Neurocognitive outcomes unchanged

A large international study has found that managing low and high blood pressure in non-cardiac surgery has no significant impact on in-hospital delirium or cognitive changes one year after surgery. The study included 2,603 patients undergoing non-cardiac surgery and compared two strategies for mean arterial pressure targeting.

Scientists say next few years vital to securing the future of the West Antarctic Ice Sheet

A study published in Communications Earth & Environment suggests that a four-meter global sea level rise could be triggered if the West Antarctic Ice Sheet collapses, with temperatures just above present-day levels being sufficient to trigger collapse. Immediate actions to reduce emissions could still prevent this catastrophic outcome.
