Article Synopsis
- Researchers observed pure biogenic new particle formation (NPF) driven by highly oxygenated organic molecules (HOMs) in a peatland in southern Finland, indicating a possible mechanism for aerosol formation similar to pre-industrial times.
- The study found that meteorological conditions created an "air pocket" at night, allowing NPF to initiate solely from biogenic HOM, providing a rare look at a pristine atmospheric environment.
- This research offers insights into how pre-industrial aerosols were formed, helping improve our understanding of the effects of aerosols on climate today and in the future, especially as air pollution mitigation efforts may return conditions closer to those of the past.
Tick-borne diseases are among the challenges associated with warming climate. Many studies predict, and already note, expansion of ticks' habitats to the north, bringing previously non-endemic diseases, such as borreliosis and encephalitis, to the new areas. In addition, higher temperatures accelerate phases of ticks' development in areas where ticks have established populations.

The trigger of the outbreak has been ascribed to the activation of spores due to permafrost thaw that was accelerated during the summer heat wave. The focus of our study is on the dynamics of local environmental factors in connection with the observed anthrax revival.

Article Synopsis
- Atmospheric reactions during haze days contribute to 80-90% of aerosol mass in Beijing, with over 65% of haze particles originating from new particle formation (NPF).
- Haze formation accelerates when the growth of newly formed particles is enhanced, indicating that nearly all haze episodes stem from NPF due to declines in primary particle emissions in recent years.
- Reducing the growth rate of fresh particles can delay haze buildup by 1-3 days and potentially halve the annual number of haze days, achievable by targeting specific gas-phase precursors like dimethyl amine, ammonia, and sulfur oxides.
