Gaming their way to sustainable development

Researchers wanted to involve local people living around Kenya and Tanzania’s Serengeti-Mara parks in developing a sustainable future for them and the parks. They developed a board game to get people talking to the researchers — and to each other. That game has now won an international award.

Testing CO2 transport on the laboratory roof

When scientists carry out experiments to investigate safe and efficient CO2 transport on the roof of the thermal power engineering laboratories at Trondheim, Norway, the noise they make will sound like a jet engine.

Svalbard reindeer populations rebounding from centuries of hunting

As reindeer go, the animals living on the Norwegian arctic archipelago of Svalbard might not be Santa’s first choice. They’re a smaller subspecies of their common mainland relatives, and to save energy they basically never run. But because they were nearly exterminated from Svalbard around 1900 — and were then protected in 1925 — the animals provide unique insights into how conservation can help species thrive.

Moose: like having wild livestock in the woods

Moose prefer to browse on deciduous trees. Then conifers take over and affect the species diversity in the forest. One researcher contends that Norwegian wildlife management is not good enough to address what happens in the wake of these large herbivores.

Computer video simulation can limit flooding

Floods are expensive and at times dangerous. But what if a computer disaster simulation game could show politicians and local people what potential floods in their town would look like?

Six years into the ice — and beyond

The Arctic’s once impenetrable ice cap is melting away, with profound consequences for everything from ocean circulation patterns to fish numbers and diversity. The Nansen Legacy Project, including NTNU biologists, chemists and engineers, is working to better understand what these changes mean for the Barents Sea and the Arctic Basin

How cancer breaks down your muscles

A solid tumour can cause muscle cells in the body to self-destruct. Many cancer patients die from the consequences. Now researchers are discovering more about how cancer cells in a tumour can take control of muscle cell wasting and trigger a chronic, serious condition.

Conflicting consequences of climate change for Arctic geese

Climate change is the big wild card when it comes to the survival of many Arctic species. A new study shows that climate change will be both good and bad for Svalbard barnacle geese populations — although the balance may tip depending upon the severity of future temperature increases and how other species react.

Predicted skewed waves – and found them

He solved a 127-year-old physics problem on paper and proved that off-centred boat wakes could exist. Five years later, practical experiments proved him right.

seaweed

Seaweed and kelp are more than food

Algae cultivation is popular, but good uses for the raw material are still lacking. Researchers in Norway are set to do something about this, with the goal of fully using this resource.

Sun and wind in a box

Renewable energy is fine, but often it’s needed at times other than when the wind is blowing or the sun makes an appearance. The energy needs to be stored – and a new method is on the horizon.

$180 million to go toward mapping world’s species

We can’t take care of the Earth’s species unless we know what species exist. A collaborative project that will help us know more is being launched in Trondheim during The Big Challenge science festival.

Planting the seeds for a bioliterate tropical country

Ecologist Daniel H. Janzen has spent virtually all of his half-century career trying to catalogue and understand the creatures in a patch of dry tropical forest in northwestern Costa Rica. Little did he realize his efforts would evolve into building a sea-to-summit conservation area — and a drive to inventory all million species in the country in partnership with the Costa Rican government.

How you can help the insect world

Many insect species are struggling. But all of us can help them, whether we live in an apartment or in a house with a garden.

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.

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.

How do species adapt to their surroundings?

Several fish species can change sex as needed. Other species adapt to their surroundings by living long lives — or by living shorter lives and having lots of offspring. The ability of animals and plants to change can sometimes manifest in apparently extreme ways.
