Why we should expect cyberattacks during major events

When Norway’s attention turns to Oslo for the King’s funeral on Wednesday, it creates a vulnerable moment in the digital sphere that hostile actors may seek to exploit. NTNU professor Basel Katt advises people to be alert.

Why making lighter and better batteries takes time

Chinese car manufacturers aren’t the only ones trying to develop new types of batteries. New materials are being tested in Norwegian laboratories to make batteries lighter, cheaper and more environmentally friendly.

Tactical urbanism for a car-free commute

Urban planning is not what it used to be. Researchers now want to use social networks and sensor data to make cities easier to navigate – and preferably on foot.

Designed to tempt: How mini AI lines up carrots to look their best

The researchers teach the packaging machine what is up and down on a snack carrot. The program runs on a small, local PC – not on huge servers in some far away cloud. The goal: To pack quickly, cheaply and attractively – so that consumers like us are tempted by locally sourced, healthy snacks.

Listening to whales – even when they make no sound

A 100-year-old equation and a fibre-optic cable off the coast of Svalbard led researchers to discover they could detect swimming whales — even if they were completely silent. The discovery broadens the tools that biologists could someday use to detect and monitor these marine giants.

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.

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.
