While toilet bowls are designed such that the contents are supposed to flush downward, scientists have known for decades that ...

Now a new term is gaining attention: nanoplastics. These particles are even tinier than microplastics – so small that they’re invisible to the naked eye. Nanoplastics are a type of ...

This year's winners of the Nobel Prize for physics collectively discovered and described a phenomenon that appears to defy common sense. Fewer notions could be so intuitively valid as the following: ...

"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic ...

How tiny plastic particles enter the atmosphere is an important question, as airborne microplastics are a potential health threat. Using a global chemical transport model, researchers have provided ...

"The smaller the particles, the more they can bypass biological ... of Co-Ingested Arsenic and Boscalid in an In Vitro Triculture Small Intestinal Epithelium Model, Microplastics (2025).

When a person breathes in smoke, pollutants and other small particles in the smoke get trapped in the mucus and phlegm. This can cause these substances to turn a much darker color. Smoke can also ...

This adaptability makes the sensor more robust to fabrication imperfections and enhances its capability to detect extremely small particles. Key features of the new sensor include ...
