Plastics leach toxins
Plastic contains thousands of chemicals. Until now, we haven’t known if these leach into the environment to any great extent. Now we know that they do.
A natural gem is being destroyed by plastic
Mausund and the Froan Nature Reserve are located in an archipelago far out to sea along the Trøndelag county coast, but they are not exactly pristine. About 25 per cent of the soil in the area contains plastic.
What is nature worth?
Climate change is not the greatest threat to the diversity of species on Earth. The main problem is that animal and plant habitats are disappearing.
Ski wax chemicals alter animals’ brains and livers
New research confirms that fluorinated compounds in ski waxes affect organs in mice.
Is weight loss harmful to tiny top athletes?
Shorebirds burn a lot of fat during their long migrations. This can release toxic chemicals that accumulate in fat cells.
Which species will be our urban neighbours?
All over the world, people are moving out of rural areas, and cities are growing. What will be the impact on resident species that live in these cities? Which will be our new plant and animal neighbours, which will have to leave town, and what does that mean for us humans?
A robotic microplankton sniffer dog
The microscopic, free-floating algae called phytoplankton — and the tiny zooplankton that eat them — are notoriously difficult to count. Researchers need to know how a warming climate will affect them both. A new kind of smart, lightweight autonomous underwater vehicle (LAUV) can help.
How a small fish coped with being isolated from the sea
A 12 000-year-old stickleback shows how species adapt.
Darwin had Galapagos finches. Norway has… house sparrows?
Uncommon lessons learned from the world’s most widespread bird.
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.
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.
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.
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.
No disadvantages to having kids early
Maturing and reproducing early hardly has any downsides. If you’re a wild boar, that is.
Bats not a threat to public health, but important for ecosystems
Bats have received a lot of negative attention, but the chances are slim that the virus that causes COVID-19 was transmitted from bats to humans. The world needs bats – in ecosystems, for pollination and for seed dispersal. On top of that, they keep harmful insects in check around our homes, on farms and in cities.
A tiny arctic shrub reveals secrets of plant growth on Svalbard
It’s not easy being a tiny willow on the wind-and snow-blasted islands of the Norwegian territory of Svalbard. It turns out that Salix polaris, the polar willow, handles these tough conditions by growing as best it can in response to July temperatures — a response that researchers recorded all over the archipelago.
Here’s how to recognize early spring birds
With some practice, you can learn to recognize some of the most common birds in northern Europe by their songs.
Arctic light pollution affects fish, zooplankton up to 200 metres deep
If artificial light shines into the Arctic Ocean during the polar night, does it matter? A new paper in Communications Biology says the answer to this is a strong yes.
Your plane travel destroys polar bear habitat
A group of polar bear researchers wants you to do more than worry about the fate of these beautiful animals. They’ve calculated how much summer sea ice is melted per metric tonne of CO2 emissions. Then you can decide if the flight you’re planning to take is worth destroying polar bear habitat.
