Children exhale significantly fewer potentially infectious particles than adults -- at least this is true for the small respiratory droplets that are predominantly produced in the lungs. Children ...

Hidden organic particles high in the stratosphere may reshape how scientists understand climate, ozone chemistry, and ...

The fields of virology, microbiology, nanoparticles, and extracellular vesicles (EVs) have grown tremendously over the past few years. Viruses, which range in size from 17 nm to ~1.5 µm, small ...

In recent years extracellular vesicles (EVs) have become one of the most studied entities due to their ability to regulate gene expression and alter the function of various cell types. There has been ...

Smaller plastic particles have more effects on neurons, the key information processing cells of the brain, new research from the University of Eastern Finland shows. In the study, neuronal cells were ...

The London Underground is key to the functioning of England’s capital city. Roughly 2 million people use it each day. But it is polluted with small particulate matter from heavy metals, including iron ...

Over the past few years, studies have suggested that plastic particles from bottles, food packaging and waste have been detected in human blood, lungs, placentas, arteries and even the brain. But a ...

Aerosols refer to fine solid or liquid particles suspended in the atmosphere, where they reside typically for days to weeks before falling to the ground or being washed out by rain or snow. They arise ...

Tiny particles such as ice crystals or ash particles tend to oscillate as they settle through the atmosphere. In their experiments, the scientists were able to track non-spherical particles of size ...

We are delighted to invite you to our upcoming Microplastics Symposium 2025: Small particles, big problems. This series of seminars on will focus on the detection and analysis of microplastics, the ...
