Scientists have predicted that certain venomous snakes could start moving into new geographies if Earth heats up by 5ºC. Using models to analyse which snake environments are likely to be affected by climate change, Pablo Ariel Martinez was able to predict where these snakes would move to. In this scenario, it’s not good news for Namibia and Niger: the model suggests they will see a major increase in venomous snakes from other countries, which could put a
strain on their public health systems.
Tuberculosis (TB) infections often go undetected – many people don’t know they carry the bacteria until they get severe symptoms of disease. One of the dangers is unknowingly infecting others. What if TB could be diagnosed by an uncomplicated skin test? Chemist Yvette Naude and her team developed a patch that can be stuck to the wrist for a few minutes to pick up TB’s chemical signals from the skin. They explain how it works and why it could be a valuable
weapon against the world’s most deadly infectious disease.
