Not enough COVID-19 tests? No problem, we’ll make them!
The story of what happened when a molecular biologist, some engineers and PhDs and postdocs from NTNU and St Olavs Hospital put their heads together to design a completely different kind of coronavirus test.
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.
Divers discover new species in Ørlandet municipality
The new species of nudibranch, Dendronotus yrjargul, is named after the municipality where it was found.
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.
How Darwin can help us with cancer and corona
Why do some organisms evolve and others don’t? The answer could help in the fight against both cancer and corona.
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.
Does Norway’s future lie at the bottom of the sea?
Low oil prices have fueled the debate about which industries Norway should develop and live on in the future. In the government’s revised national budget, the extraction of seabed minerals emerges as a clear investment area.
Mystery of the blunt-tipped beetle penis
It took seven years, countless beetle penis field investigations, and hours upon hours on hands and knees in coastal wetlands. This is the story of all the research that has to happen before a new species can finally get its official name.
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.
