One of the biggest challenges in the scientific response to the coronavirus pandemic is how little is known about the pathogen and the disease it causes. Our coverage over the past week reflects this search for understanding in a few stories, including one on asymptomatic spread and another exploring the role of genetics in the symptoms and severity of COVID-19.
To understand how the Bluetooth-based system for contact tracing works – and the privacy implications – I recommend this deep dive. And for something totally different, results of a research study, with video, on the impact of road building on Asia’s tiger population.
