Grades shouldn’t be introduced too early
Assigning marks in Grade 7 can have negative effects. A new study shows that the practice can affect pupils’ academic performance and how they experience the transition to secondary school.

Mapping the conflict between farming and biodiversity
A new study provides the most detailed dataset yet on the biodiversity footprint of food. The results can lead to more sustainable diets.
New video offers a peek into Lake Mjøsa shipwreck
The discovery of what may be Mjøsa’s oldest known shipwreck to date drew international attention just before last Christmas. The researchers have now secured a video of “Storfjorden I.”
Pupils are making circular art for Oslo’s first ‘energy-plus’ school
Recycling is the guiding principle behind the new Voldsløkka school and Culture Centre. Pupils are taking part in an art project as their contribution to the research project called ARV.
Data is just as important as the electricity we generate from the sun and wind
During his visit to Norway earlier this year, Bill Gates was keen to emphasise the innovation that will be needed to reduce the costs of mitigating climate change. One place to start is to educate more experts in the field of data processing.
Gaining a better overview of life on earth
Approximately 47 000 different species have been identified in Norway – and there are probably many more. A new tool can help us gain a better overview.
Winter salting caused the crash – not the steel
Speciality steels made the headlines in 2021 following a serious car accident. Normally, alloys of this type corrode very slowly, but they must not be used to construct barriers along roads that are salted in winter. At other places on the road network, the same steels offer long lifetimes and cost savings.
To avoid a battery crisis, more of us should share small, lightweight EVs
Fossil fuel vehicles gulp down petrol, and electric cars gobble up minerals. The battery industry is so ravenous for lithium as a raw material that researchers believe the demand could threaten climate goals.
Sexually active women are not judged more harshly than men
It’s not true that women are subjected to sexual double standards, researchers say. Most people tend to be more liberal than they think other people are. But not all behaviour is OK.
Predicting how CPR will work minutes ahead
After examining 298 patients with cardiac arrest, researchers found that ECG markers can provide a clue as to how the treatment is working — as much as four to five minutes into the future.
Supergenes helped bring alien plant to Norway
The plant is called common ragweed, and if you are allergic to pollen, you should probably pay extra close attention. This is one of the invasive plants that supergenes have brought to Norway.
All you need to know about saving a life out in the cold
Why are cold temperatures so dangerous if you have an accident? And why is it that cold temperatures enable some patients to survive without permanent harm?
150 hydrogen-powered trucks ready to roll on European roads
Haulage truck and fuel manufacturers have joined forces with researchers to make heavy transport across Europe more climate-friendly. And all thanks to having SINTEF ‘behind the wheel’.
There are easier ways of integrating solar power into the energy system
We need the electricity generated by solar panels in order to meet our climate change mitigation targets. But solar power must be integrated rationally and fairly – something that can only be achieved with effective regulation.
Tracking whales as they cruise the Arctic
For the first time ever, researchers have been able to track eight fin whales in near real time for five hours, as they swam along a stretch of fibre-optic cable line in the Arctic. The breakthrough suggests that fibre-optic cable networks could be harnessed to help prevent whale deaths by ship strikes.
The Middle Ages here and now
Medieval times may seem dusty and distant, but we are surrounded by the Middle Ages in many different ways in our daily lives.
Electric car batteries are difficult to recycle – at least for now
Electric cars are a growing market, and so are the large batteries they use. Often these batteries are difficult to recycle. But help is on its way.
Artificial intelligence could secure the power supply
Managing hydropower production is complicated. Artificial intelligence can help ensure that we don’t run out of power.
We know that carbon capture from the atmosphere is possible. But how do we get there?
Direct Air Capture (DAC) technologies offer new opportunities for getting closer to our climate change mitigation targets. However, we still have a long way to go before DAC can be fully rolled out as a mitigation measure.
The New Atlantis – more and more of the world is underwater
Most of our planet is underwater – and steadily more will be underwater in the years to come. What do we really know about the underwater world?
When will we see a ‘Spotify’ for spare parts?
Vessel components are being transported all around the world when just a simple datafile would suffice.
When your house spreads gossip about you
Security holes in our smart devices are difficult to detect. Is it possible to automate the search for vulnerabilities? Researchers at NTNU in Gjøvik are on the case.
Bacteria could make salmon healthier
Bacteria-free fish fry put researchers on the track of how they could make fish more disease resistant.
Carbon capture using sunlight and mirrors
Researchers are planning a solar energy plant that will capture ‘concentrated sunlight’ using mirrors. The plant will also be distinctive because it will generate both electricity and heat, which can be used to capture carbon dioxide.
