Scientists have discovered a new mechanism that cells use to control the transport of fats between different cellular compartments, a process vital for maintaining healthy cell function. They identified a protein called Hoi1 that acts as a guide, directing fat-transport machines to the right location at the cell’s membrane, which is crucial for managing cholesterol levels.

An analysis of fish populations shows that marine heatwaves have opposite effects depending on location: they can boost fish numbers in colder, northern regions but cause declines in warmer, southern areas. This reveals how climate change is reshaping ocean ecosystems in complex, location-specific ways, with major implications for fisheries and biodiversity.
