From one gene switch, many possible outcomes

A team of researchers has discovered that subtle changes in a lipid-binding region can dramatically alter the function of transcription factors in plants. By swapping the START domains of two near-identical paralogs, PHB and CNA, the researchers demonstrated that this single change could rewrite developmental instructions.

Q&A: What fossils reveal about ancient Australian forests and fire

Fossil evidence from Australia and South America challenges prevailing narrative that eucalypt forests are under siege from expanding rainforests. The study suggests that fire became a feature of these vegetation interactions in Australia around five million years ago, making large-scale fire interventions unnecessary.

Opioids interfere with cancer immunotherapy but these drugs could help

New research from the University of Pittsburgh found that opioids can suppress the immune system and reduce the effectiveness of immunotherapy for head and neck cancer. However, peripherally restricted OPRM1 antagonists (PAMORAs) may block opioid-induced immunosuppression and improve response rates to immune checkpoint inhibitor therapy.
