An assessment of sensitivity to increasing temperature for thousands of insect species in mountainous terrain reveals a risk of insect biodiversity loss in tropical lowlands.

Metastasis occurs when cancer cells spread to other organs and escape elimination by the immune system. Analysis reveals that these cells resist killing by immune cells by harnessing stress-hormone signalling through the glucocorticoid receptor, suggesting a potential therapeutic target for preventing metastasis.
