A fresh wave of biology research is making headlines. First, scientists have uncovered why drinking alcohol can be especially harmful to the liver: alcohol triggers the body to produce its own fructose, a type of sugar, which then fuels liver damage. The study suggests that cutting out sugar, not just alcohol, could be key to protecting liver health. Next, a team led by Academician Lu Lin has painted a detailed picture of sleep problems across China. Their review reveals how common sleep disorders are, the biggest obstacles to better sleep health, and practical strategies the country can adopt to improve rest for millions of citizens. In cancer research, Lei Qunying’s group discovered that a molecule called acetyl‑CoA acts as a signal that controls the recycling of damaged mitochondria (mitophagy). This signaling pathway also explains why some tumors resist drugs that target the KRAS gene. The finding opens the door to new combination therapies that could overcome this resistance. Finally, a collaborative paper from the Chinese Academy of Sciences and Lanzhou University traces the intertwined journeys of dogs and humans over the past ten thousand years, showing how the two species migrated together and influenced each other’s evolution. These studies together highlight the diverse ways modern biology is reshaping our understanding of health, disease, and our shared history with animals.
