What sweat and saliva tell us

Sugars come in all shapes and sizes. We need them for energy and we enjoy them, but complex variants may also be used as medicine.

The universe is decaying much faster than thought. This is shown by calculations of three scientists at Radboud University on the so-called Hawking radiation. They calculate that the last stellar remnants take about 10^78 years (a 1 with 78 zeros) to perish. That is much shorter than the previously postulated 10^1100 years (a 1 with 1100 zeros). The researchers publish their findings, with a wink and dead-seriously, in the Journal of Cosmology and Astroparticle Physics.

A new study reveals that nearly 70% of climate adaptation plans in European cities contain significant inconsistencies, severely limiting their effectiveness in addressing rising climate risks. "As Europe warms twice as fast as other continents, this 'adaptation gap' poses growing threats to the 75% of Europeans who live in cities", says UT researcher and lead author Diana Reckien.

Nitrous oxide is known as the gas used in whipped cream cartridges or as an anaesthetic in hospitals. But it's much more than that. This potent greenhouse gas is also released from biological wastewater treatment plants (WWTPs), posing a real threat to our climate. PhD candidate Nina Roothans (TU Delft), who recently graduated cum laude, has identified practical strategies to reduce nitrous oxide emissions. Her groundbreaking work has now been published in Nature Water .
