Crowding-induced stress gives mackerel the blues

Researchers have succeeded in showing that mackerel turn blue when under stress. This new knowledge will better enable our fisheries to safeguard fish welfare and will optimise catch quality into the bargain.

A failed democratic experiment?

This is how the democratic process is described in several of the former Soviet states that won their freedom starting in the 1990s. Now researchers want to propose new ways of building democracy.

Companies need to report their climate risks

Regulators across the globe regularly require publicly traded companies to tell their stockholders about potential financial risks. A March proposal from the US Securities and Exchange Commission (SEC) would require companies to disclose the risks that climate change poses to their financial health. Adopting the rule is an important step for the climate, researchers say.

Will Industry 5.0 herald the revenge of the humans?

The fourth industrial revolution (Industry 4.0) put automation, digitalisation and robotisation very much in the driving seat. But something was missing. The introduction of Industry 5.0 will hand control back to you and me.

‘Bio-batteries’ enable us to store solar and wind energy

Up until now it has been a challenge to store the energy we generate when the sun is shining and the wind is blowing. But researchers at a laboratory in Trondheim in Norway have succeeded in doing just this – and entirely without any form of advanced battery technology.

How useful or necessary is homework?

This topic is one of several addressed in an updated Norwegian Education Act that is currently out for comments. Several researchers are sceptical about the benefits of homework.

Why there is still hope for our planet

Is it too late to save our planet? Professor Jianguo Liu is the newest winner of The Gunnerus Award in Sustainability Science. He offers us some hope.

How terrorism affects our attitudes

Some types of terrorist acts affect people much more than others. Islamist violence apparently produces the strongest counter-reactions.

How does light impact our school pupils?

Did you know that light is a factor that affects both learning and the psychological development in school children? The right kind of light can boost performance in reading, writing and maths, and suppress restlessness and aggression.

Is it really selfish to complain about electricity prices?

Norwegians are not necessarily being selfish by wanting to go back to the good old days of cheap electricity. Nor do people think it is acceptable to use the situation for some to enrich themselves at the expense of others, says the researcher.

Making bike-sharing work

Bike-sharing is a way for cities to cut their greenhouse gas emissions while limiting urban congestion. But bikes have to be available when and where people want them. A new approach can help by ensuring bikes are in the right place at the right time.

Algorithms can prevent online abuse

The number of abuse cases against children via the internet has increased by almost 50 per cent in five years, according to the Norwegian Broadcasting Corporation. Researchers at NTNU in Gjøvik have developed algorithms that can help detect planned online grooming by analysing conversations.
