New technology will identify sources of plastic in the ocean
Plastic trash gets cleaned up along our beaches. But it’s also important to find out where the plastic comes from. A Norwegian app will soon be able to do this.
Building trust in robots to measure, monitor, and regulate the ocean
A new partnership between the Centre for the 4th Industrial Revolution Ocean and the Norwegian University of Science and Technology (NTNU) has been established to establish trust in ocean data collected from autonomous underwater vehicles.

Shedding light — on the polar night
The polar night is dark — if you’re a person. But not if you’re a krill or a seabird or a fish. In the first episode of NTNU’s new English-language podcast, 63 Degrees North, learn how researchers discovered that there’s more than enough light in the polar night for the tiny creatures who live there.
Abandoned cropland should produce biofuels
More biofuels are needed to counteract climate change. But producing them shouldn’t diminish food production or wilderness areas. The solution may be to grow more grass on recently abandoned cropland.
Skinnier but resilient geese thriving in the high Arctic
Barnacle geese in the Arctic have been on a diet. So many now migrate to northern breeding grounds that in some places there’s less food to go around. The good news is that it doesn’t seem to restrict their population growth — yet.
Global warming is faster than evolution
If global warming happens too quickly, not all species will be able to adapt in time.
NTNU researcher wins ERC Consolidator Grant
The EU has awarded two million euros for research on how animals are coping with climate changes.
Species more likely to die out with rapid climate change
The great tit and other birds can adapt to changes in their food supply as a result of climate change, but they run into trouble if the changes happen too quickly.
Losing ground in biodiversity hotspots worldwide
Agriculture is eating into areas that are important in protecting some of the most biologically diverse places on the planet. Most of this new agricultural land is being used to grow cattle feed.
Water fleas on “happy pills” have more offspring
Dopamine can trigger feelings of happiness in humans. Water fleas that are exposed to dopamine-regulating substances apparently gain several advantages.
Bioplastics no safer than other plastics
Bioplastics contain substances that are as toxic as those in ordinary plastics.
Battling harmful insects by understanding their sense of smell
The larvae of cotton bollworm attack our food. But the adults pollinate plants. So how can we stop them from destroying crops without using poison? Researchers in Trondheim are on the case.

Red fox displaces Arctic fox thanks to littering
Red foxes are moving to the mountains to feed on trash along roadsides. This is bad news for the endangered Arctic fox.
Inbreeding detrimental for survival
Inbred birds don’t live as long and have fewer offspring than non-inbred birds. Inbreeding is equally harmful regardless of where the birds live.
Panthera leo’s family tree takes shape
Once upon a time, lions were the world’s most widespread mammals. Now we know more about their genealogy – and that could make it easier to help the species survive.
