Cold exposure in mice activates brown fat to deny tumours glucose, and the future of extreme heatwaves.

00:45 How cold temperatures could starve tumours

A team of researchers have found that exposing mice to the cold could starve tumour cells of the blood glucose they need to thrive. They showed that the cold temperatures deprived the tumours of fuel by activating brown fat – a tissue that burns through glucose to keep body temperature up. The team also showed preliminary evidence of the effect occurring in one person with cancer, but say that more research is needed before this method can be considered for clinical use.

11:24 The future of extreme heatwaves

Climate scientists have long warned that extreme heat and extreme heatwaves will become more frequent as a result of climate change. But across the world these events are happening faster, and more furiously, than expected, and researchers are scrambling to dissect recent heatwaves to better understand what the world might have in store.
