Catalyst cleans up CO2 better with different preparation

An international research team led by Bert Weckhuysen (Utrecht University) and Sara Bals (University of Antwerp) has shown that a promising catalyst for clearing CO2 becomes significantly more active and selective if its ...

Structure of hepatitis B virus mapped

Using a newly developed method, Utrecht University researchers have mapped the structure and composition of the hepatitis B virus. The researchers were able to map the structure by spraying the virus.

Can a computer chip have zero energy loss in 1.58 dimensions?

What if we could find a way to make electric currents flow, without energy loss? A promising approach for this involves using materials known as topological insulators. They are known to exist in one (wire), two (sheet) and ...

Intensified ice sheet movements do not affect rising sea levels

Meltwater is rapidly increasing the tempo of glacial movements on the rim of the Greenland ice sheet. Over the long term, however, this process is interrupted as meltwater drains away via broad channels, as a result of which ...

Climate change tipping points may be too simple a concept

We regularly hear warnings that climate change may lead to 'tipping points': irreversible situations where savanna can quickly change into desert, or the warm gulf stream current can simply stop flowing. These cautions often ...

Microfossils shed light on the long fossil record of euglenoids

Hiding in the shadows, euglenoids are a fascinating group of single-celled protists that are neither plant nor animal. Plants photosynthesize, and animals eat. Euglenoids do both. Spiraling along the murky bottoms of shallow ...
