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.
New website allows data sharing for upcoming Climate Panel report
NTNU researchers are playing a leading role in a new IPCC report. One way they’re helping is collecting data on a website created and operated by the university.
A simple way of describing friction — by making it complicated
We all know what friction is — but it turns out to be very difficult to describe. Researchers have simplified a commonly used, century-old model for use at the nanoscale — by making it more complicated.
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.
Norway to start broad-based testing by month’s end using NTNU test kits
Norway’s Ministry of Health and Care Services confirmed Friday that it will roll out coronavirus test kits developed by researchers from NTNU and St Olavs Hospital by the last week of April/early May. The kits will more than triple Norway’s testing capacity during the rollout.
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.
Thinking outside the box of fossils
During the time of Darwin, anthropogeny was the study of human origins. Its sub-discipline paleoanthropology has since taken over, which focuses on fossils found in dry parts of Africa. These fossils don’t tell us much about why or where humans actually evolved.
Abandoned cropland helps make Europe cooler
As nations prepare to mitigate climate change, decision makers need to understand how land use fits into the climate equation. A new study looked at land use changes over two decades and found a major shift from cropland to forests. That change made western Europe cooler.
Following sea trout minute by minute
Sea trout populations have declined sharply. Researchers have studied the life of sea trout by means of acoustic telemetry tags and listening stations. Now they know more about what we need to do to protect the sea trout population.
The most beautiful solar cells are inspired by nature
Organic solar cells are usually less effective than silicon solar cells. But there is still a market for them – and they’re beautiful and exciting.
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.
Trees struggle when forests become too small
As forest areas shrink and become fragmented, many tree species face problems. They often rely on animals that can no longer disperse their seeds effectively.
Making beer super fast from ancient Norwegian yeast
The distinctly Norwegian beer-brewing yeast kveik reduces fermentation time drastically. That’s a huge advantage, according to NTNU PhD candidate Christian Schulz.
Climate change fuels Australia’s enormous wildfires
Bushfires are a normal part of the cycle of nature in Australia. But not like this. And it is going to get worse.
Ocean acidification a big problem — but not for coral reef fish behaviour
Several high-profile studies report that ocean acidification will affect coral reef fish behaviour enough to jeopardize their survival. One research team looked more deeply at this assertion — and found it is simply not true.
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 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?
Insect or virus? How plants know
How can plants defend against different threats to their cell walls?
