Researchers look ahead to the potential uses and benefits of a technology that has been more than 20 years in the making.

Ancient humans painted scenes in Indonesian caves more than 45,000 years ago, but their art is disappearing rapidly. Researchers are trying to discover what’s causing the damage and how to stop it — before the murals are gone forever.

Blood plasma protein data was combined with machine learning models for a simple method to determine differences in organ-specific aging; the study provides a basis for the prediction of diseases and aging effects using plasma proteomics.

Planet-altering climate ‘tipping points’ are looming — but positive behavioural and economic shifts could result in runaway benefits for the climate. Plus, scientists race to save ancient cave paintings and how the clumsy use of AI is fuelling the reproducibility crisis.
