Nanoplastic omnipresent in rural and remote surface waters

Over the past few decades, tiny pieces of plastic have found their way, via the air, to remote places on Earth. This is the worrying conclusion drawn by researchers from Utrecht University and other institutes published in ...

Protons are likely smaller than previously believed

A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. The discrepancy surprised the scientific community; some researchers even believed that the Standard ...

Approaching the Heisenberg limit

A football is not a quantum particle. There are crucial differences between the things we know from everyday life and tiny quantum objects. Quantum phenomena are usually very fragile. To study them, one normally uses only ...

Reliably measuring whether rivers or lakes run out of air

Wastewater carries large quantities of organic substances into the rivers and lakes, leading to heavy growth of bacteria and oxygen deficiency. Measurement methods have so far been incapable of measuring this organic pollution ...

Using quantum measurements to fuel a cooling engine

Researchers at the University of Florence and Istituto dei Sistemi Complessi, in Italy, have recently proved that the invasiveness of quantum measurements might not always be detrimental. In a study published in Physical ...

River levels tracked from space

The 4,300 kilometer Mekong River is a lifeline for Southeast Asia. If this mighty river system bursts its banks, flooding can affect the lives and livelihoods of millions of people. A new method developed by a team of researchers ...
