New nanomaterial to replace mercury

Ultraviolet light is used to kill bacteria and viruses, but UV lamps contain toxic mercury. A newly developed nanomaterial is changing that.

Reindeer adapt to climate change by eating seaweed

The arctic archipelago of Svalbard is already experiencing dramatic effects from climate change. A new study shows how these changes can force wild reindeer to graze on seaweed, a strategy that increases their likelihood of survival— and is recorded in their poop.

The women behind the periodic table

Textbooks and media can give the impression that the periodic table was the work of one man, but did you know that many of the contributors behind nature’s most important system were women?

New drones check ships for cracks and rust

Inspecting ship tanks and storage spaces underwater is a challenging task for humans. A start-up company that originated at NTNU is manufacturing autonomous drones that can take over the job – and do it more cheaply.

Carbon capture is cheaper than ever

According to a new report, many years of research effort have resulted in significant reductions in the cost of full-scale carbon capture and storage.

Finding ways to use less salt on snowy roads

It’s springtime in much of the northern hemisphere, although spring snowstorms are still possible. When that happens, salt trucks and ploughs help make roads safe. But road salt can be bad for the environment, and can rust cars, bicycles and other metal. New research shows that salt use can be safely — and substantially — cut in certain circumstances.

When the extreme becomes the norm: Svalbard reindeer cope with dramatic climate change

Climate change is increasing the likelihood of extreme winter rain events in the Arctic. These kinds of winter storms on Norway’s Svalbard archipelago can cause a thick cap of ice to cover the forage that reindeer eat. You’d think that more frequent rain-on-snow events would spell the end for these arctic animals — but you’d be wrong.

Teaching on Mount Everest and Mars

In the virtual world, inaccessible places become accessible. NTNU uses virtual reality – or VR – technology to create new teaching methods.
