A new imaging method takes snapshots of atomic nuclei smashing together in high-energy collisions to help physicists better understand their shapes. Nuclei can take on a variety of forms, which can be tricky to predict: some are rigid and some fluctuate between several. The new method tracks the momentum of thousands of particles that result from collisions and matches the results with models to "roll back the clock to infer the shape of the nuclei", says physicist Jiangyong Jia.
Researchers and environmental advocates want governments to offer financial incentives to farmers who use 'regenerative' practices to climate-proof farmland. They say that by improving soil health, crops can be made more resilient to drought and extreme weather. Practices such as rotating crops between fields can boost the diversity of microbes in the soil, helping it to retain nutrients and absorb water. Farmers who spoke to Nature say that regenerative agriculture does work, but it can take a few years of implementing it before farms start to see a profit.
