Molecular tests for TB

A potential game-changer in the tuberculosis epidemic was how the tuberculosis community viewed rapid molecular tests for tuberculosis and tuberculosis drug resistance. This was 12 years ago, with the launch of Xpert MTB/RIF, which gives results in les…

Protecting species for the good of global climate

Until now, measures to protect climate and biodiversity have often been developed in parallel. However, this is now considered outdated because many approaches can protect both climate and biodiversity. Scientists have now assessed the role of the pote…

Learning chemical networks give life a chiral twist

A study shows that the preference of biological molecules for left or right-handedness — a hallmark of living matter — could emerge spontaneously as prebiotic chemical networks adapt to optimize energy harvesting. The proposed mechanism of symmetry b…
