From dengue to Ebola, laboratories in Asia and Africa are using sequencing technology and skills acquired during the pandemic to track endemic diseases quickly.
Plants have immune systems that defend them against various disease-causing microbes. One virus targets plant hormone receptors to help it to infect plants. As a defence, a plant has evolved an immune receptor that mimics hormone receptors, recognizes a virus-encoded protein and triggers immune defences.
Estimating the number of deaths attributable to COVID-19 around the world is a complex task — as highlighted by one attempt to measure global excess mortality in 2020 and 2021.
Cost-of-living crises, labour shortages and the impact of global politics on research collaborations were among the challenges faced by working scientists in a tumultuous year.
Atmospheric methane concentrations rose unexpectedly during the lockdowns of 2020. It now seems that this was due to warm, wet weather in the Northern Hemisphere and, ironically, a slowdown in air-pollutant emissions.
Discover our pick of the best science shots of 2022. Plus, a nuclear-fusion lab achieves ‘ignition’ and nine sites that could describe a new geological epoch.
The therapeutic options available to treat ovarian cancer need improvement. Data that reveal the cellular, molecular and mutational landscape as such tumours grow and spread might aid efforts to develop new targeted therapies.
Microorganisms in the gut produce molecules that activate sensory neurons, stimulating exercise-associated reward circuits in the brain. This newly discovered pathway in mice affects motivation for prolonged exercise.
