The magical reindeer nose

Every schoolchild knows about Rudolph the Reindeer and his magic red nose. But Rudolph’s real-life counterparts really do have a magic nose. The colder it is, the better it is in keeping the animals warm and hydrated.

Researching the dark side of microplastics

Minute particles of plastic, called microplastics, are everywhere. An international research team is now about to investigate how toxic microplastics are to marine animals such as plankton, crabs and fish, and to find out if such plastics accumulate in the food chain.

Charting riches in the ocean depths

The deep sea contains mineral riches that offers a new frontier for research and exploration — and a new way to employ Norway’s deep sea expertise.

Kon-Tiki2 expedition in Heyerdahl’s wake

The Kon-Tiki2 expedition aims to both reinforce and challenge Heyerdahl’s theories – and NTNU will gather unique research material from the major oceans that the expedition crosses

Timing is everything for renewable energy use

There’s no time to waste in shifting to renewable energy sources if we are to avoid dangerous climate change. That’s especially true when it comes to bioenergy, which causes a temporary increase in CO2 levels that is later removed as replacement biostocks grow.

Uncovering secrets of ice that burns

Methane hydrates can be seen as a potential energy source or as a dangerous source of methane – a greenhouse gas that is 20 times more potent than CO2. With the help of a supercomputer and an interdisciplinary team, scientists have uncovered important details about their stability if they are disturbed by human-induced or natural forces.

Turning political pledges into action on climate change

Beginning on 30 November, the nations of the world will gather in Paris to discuss a new global agreement on climate change. But what will it take to transform international political will into real action to curb global warming?

Many memories, many rooms

2014 NOBEL PRIZE: The brain has an enormous capacity to store memories and to keep memories from getting mixed up in part because of how these memories are stored in the hippocampus, researchers from NTNU’s Kavli Institute for Systems Neuroscience have shown.

Extreme weather in the Arctic causes problems for people, wildlife

The last week of January 2012 brought wild weather to the Norwegian arctic island archipelago of Svalbard and its largest town, Longyearbyen. A new cross-disciplinary study provides a comprehensive look at the effects of this extreme weather event on everything from town infrastructure to the natural environment.

A new solution to an age-old equation can improve ship efficiency

It’s been this way for 127 years— the V-shaped wake pattern behind a ship moving in a straight line always has the same central angle. But a Norwegian armed with a pen and a piece of paper has discovered that in certain situations, a boat’s wake can actually be found in front of the boat.

Capturing false hormones

They damage our ability to reproduce, and they pollute the natural environment. Yet chemicals known as hormone mimics can be found in consumer goods. Eventually they end up in our water. But we now have a way of capturing them.

The secret life of the sea trout

Armed with special acoustic tags, a team of researchers is following 50 individual fish for as long as seven months to learn more about their life – and death — in Norwegian fjords.

Secrets of the High North

The Norwegian arctic island archipelago of Svalbard offers scientists the chance to investigate some of the most intriguing – and perplexing – puzzles facing the high north.
