Climate change threatens rare temperate rainforests

A new study warns that climate change could lead to the loss of up to 68% of the world's temperate rainforests by 2100, highlighting the urgent need for action. The UK has a quarter of the world's potential for restoration and is resilient to low and medium amounts of future warming.

How immune cells “sniff out” pathogens

Researchers from the University of Bonn have developed a new method to study immune receptors using a label-free biosensor assay. This approach allows for the detection of specific chemical signals that activate Toll-like receptors (TLRs), which are found on the surface of immune cells and play a crucial role in detecting infections. T...
