Time-tested magnesium oxide: Unveiling CO₂ absorption dynamics

Magnesium oxide is a promising material for capturing carbon dioxide directly from the atmosphere and injecting it deep underground to limit the effects of climate change. But making the method economical will require discovering ...

Control over friction, from small to large scales

Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, even at large scales, ...

Putting sound waves to work to create safer public spaces

The risk of hearing loss does not come just from loud machinery or other obvious noise. It can also affect people in public environments like theaters and concert halls. Absorbing this excess sound to make public environments ...

Model shows how fish synchronize tail fins to save energy

Researchers from Tohoku University have developed a model that simulates the motion of fish tail fins. The model uncovers the underlying mechanisms behind a commonly observed phenomenon in fish: how they synchronize the movement ...
