After a person takes the psychedelic compound psilocybin, some of their brain networks dissolve — especially the one involved in the perception of self, space and time. Changes to the connections to this network can last for weeks.

Compounds containing copper have long been targeted in the search for high-temperature superconductivity, but experiments performed at extreme pressures suggest that nickel-based materials might also be candidates.

Can forest-degradation thresholds be identified to assess whether logged sites have conservation value? A long-term multi-species study reveals the effects on biodiversity when tropical forests are logged at differing intensities.

How plants sense their orientation in relation to gravity and steer their root and shoot growth accordingly is not fully understood. The discovery of key steps needed for this process fills in some of the gaps in our knowledge.
