New emergency towing equipment allows rescue helicopters to fly farther and in worse weather

In the Lofoten archipelago off Norway’s northern west coast, a rescue helicopter circles over a cruise ship. Soon, two people and a large bag are lowered onto the deck. Then a line is launched over to the coast guard ship that is right next to it. The cruise ship is ready to be towed. Fortunately, this is only an exercise to test the new equipment and not a real emergency.

Light environment in fish farms hinders salmon’s sleep rhythms

What happens when you disrupt a fish’s natural rhythm? The use of light in fish farms can stress the fish and prevent them from sleeping or developing properly. New research now makes it possible to measure light from the fish’s point of view. This could greatly improve fish health.

Underwater robots that are always on call

More than 70 per cent of the Earth is covered by oceans. An increasing amount of critical infrastructure is being installed on the seabed. Sabotage and accidents increase the need for inspection and monitoring. These measures are currently very expensive, but the hope is that they can soon be carried out by robots that are permanently stationed on the seabed.

This technology makes it possible to be a seafarer—on land

Uncrewed vessels that navigate themselves and notify operators when they need support from shore-based navigators. However, such ships also require an international regulatory framework. Now, the first version is in place, largely thanks to Norwegian research.

Thermal resistivity (heat resistance) describes how much a material resists heat conductivity. Soil materials like sand, crushed stone and other masses around power cables have great importance for the cable's current-carrying capacity. Photo: Kristian Solheim Thinn, SINTEF.

Supercharging our grid: How to free up 20% more power

Implementing effective monitoring measures could yield much more energy from the cable network – all without digging a single new trench. Just a dream scenario? No, it is entirely possible, say researchers.

A strange humming phenomenon

Do you occasionally hear a low buzzing or humming sound that doesn’t have a clear source? Then you’re among the estimated 2-4 per cent of the world’s population who hear this. Scientists have been trying to figure out for decades where this sound comes from.

Preventing wildlife collisions in new ways

Wildlife fences and wildlife crossings are expensive – and they have mixed results. Now researchers have studied what is needed to prevent cars and trains from colliding with animals.

The impact of microplastics on ocean carbon uptake

Marine microplastics affect algae’s ability to grow and photosynthesize. Researchers have now calculated what impact this has on the greenhouse effect and the ocean’s ability to absorb carbon dioxide.

Recycling old clothes into new fabrics

Huge amounts of clothing are simply discarded, and almost nothing goes to reuse or recycling. But with sensors and artificial intelligence, textile waste can be sorted so carefully that far more could be recycled – and turned into new clothing.

Body weight affects your gut microbiota

Your body weight and genes influence the types of bacteria you have in your gut. In turn, this appears to affect the risk of developing conditions such as coeliac disease and haemorrhoids.

Exercise: a very little goes a long way

Don’t have time to exercise because of a busy schedule? Or are you simply not very motivated? You’ll be pleased to learn that just 10 minutes of exercise every other day is all it takes. However, you really need to exert yourself during those 10 minutes.

An autonomous “flying” boat

This past winter, people in Trondheim have caught glimpses of a boat that seems to fly over the water out on the fjord. Many have also taken part in test trips. NTNU researchers have investigated what it will take for people to trust a boat that runs almost without a crew on board.
