00:46 Designing new antivenoms to treat snakebites

Researchers have shown that machine learning can quickly design antivenoms that are effective against lethal snake-toxins, which they hope will help tackle a serious public health issue. Thousands of people die as a result of snakebites each year, but treatment options are limited, expensive and often difficult to access in the resource-poor settings where most bites occur. The computer-aided approach allowed researchers to design two proteins that provided near total protection against individual snake toxins in mouse experiments. While limited in scope, the team behind the work believe these results demonstrate the promise of the approach in designing effective and cheaper treatments for use in humans.

13:53 Earth breaches 1.5 °C climate limit for the first time

News broke last week that in 2024, Earth’s average temperature climbed to more than 1.5 °C above pre-industrial levels for the first time. Although this is only a single year so far, we discuss what breaking this significant threshold means for the 2015 Paris climate agreement and what climate scientists understand about the speed that Earth is heating up.
