AbstractHeterogeneous reactions of NO2 on particulate matter have been considered an important source of HONO (Nitrous acid) in the troposphere, whereas its contribution is controversial due to the lack of uptake coefficient of NO2 (γNO2) on the surfaces of ambient particulate matter (PM). Here we investigate the the γNO2 to form HONO and its evolution based on long-term comprehensive field observations (2019–2023) in Beijing and a random forest model with Shapley additive explanations.

Thirsty cockatoos get the hang of fountainsA flock of sulphur-crested cockatoos (Cacatua galerita) in western Sydney have learned to operate drinking-water fountains. The behaviour is made possible by the dexterity of the cockatoos’ feet, which gives them an edge over other brainy birds such as crows (Corvus corone) at this kind of task, says behavioural ecologist Vladimir Pravosudov.

AbstractDrought is one of the most common and complex natural hazards affecting the environment, economies and populations globally1,2,3,4. However, there are significant uncertainties in global drought trends4,5,6, and a limited understanding of the extent to which a key driver, atmospheric evaporative demand (AED), impacts the recent evolution of the magnitude, frequency, duration and areal extent of droughts.

The cancer cells of some men feature a striking mutation: their Y chromosome is missing altogether. Now, tantalizing research suggests that this mutation can spread ‘contagiously’ from tumour cells to immune cells, which lose their cancer-fighting prowess after their Y chromosome disappears. The evidence for the contagion mechanism is not definitive.
