New drones check ships for cracks and rust

Inspecting ship tanks and storage spaces underwater is a challenging task for humans. A start-up company that originated at NTNU is manufacturing autonomous drones that can take over the job – and do it more cheaply.

Carbon capture is cheaper than ever

According to a new report, many years of research effort have resulted in significant reductions in the cost of full-scale carbon capture and storage.

Finding ways to use less salt on snowy roads

It’s springtime in much of the northern hemisphere, although spring snowstorms are still possible. When that happens, salt trucks and ploughs help make roads safe. But road salt can be bad for the environment, and can rust cars, bicycles and other metal. New research shows that salt use can be safely — and substantially — cut in certain circumstances.

When the extreme becomes the norm: Svalbard reindeer cope with dramatic climate change

Climate change is increasing the likelihood of extreme winter rain events in the Arctic. These kinds of winter storms on Norway’s Svalbard archipelago can cause a thick cap of ice to cover the forage that reindeer eat. You’d think that more frequent rain-on-snow events would spell the end for these arctic animals — but you’d be wrong.

Teaching on Mount Everest and Mars

In the virtual world, inaccessible places become accessible. NTNU uses virtual reality – or VR – technology to create new teaching methods.

How do species adapt to their surroundings?

Several fish species can change sex as needed. Other species adapt to their surroundings by living long lives — or by living shorter lives and having lots of offspring. The ability of animals and plants to change can sometimes manifest in apparently extreme ways.

Well-known drug has less risk for preterm delivery in PCOS

Metformin significantly reduces the risk of late miscarriages and preterm births for women with PCOS. But the drug does not work to prevent gestational diabetes, according to a large Nordic study from NTNU and St. Olavs hospital.

Tourism, aquaculture and offshore accidents with Blueye

Blueye is an underwater drone that got its start at NTNU. The drone can be used for serious purposes – such as when it mapped damage to the Norwegian frigate Helge Ingstad – or for entertainment, such as showing cruise passengers the underwater landscape.

Ocean life in 3-D: Mapping phytoplankton with a smart AUV

Phytoplankton form the base of the marine food chain but are notoriously difficult for scientists to account for — a little like trying to identify and count motes of dust in the air. A truly independent underwater vehicle shows it can do the job.

Basic safety measures will save lives in tunnels

What has to happen to facilitate more effective rescues from tunnel fires? Researchers have been investigating how 80 research subjects wearing VR glasses reacted in a virtual tunnel fire. Their conclusion is that basic measures can save lives.

Electric motors go to print

Even electric motors can be made more environmentally friendly. A Norwegian start-up company is on it.

Making artificial intelligence understandable for the rest of us

Humans have developed machines that can learn on their own. Machines using artificial intelligence develop “behaviours” based on their interpretation of data. But we know less about how they teach themselves. Professor Harald Martens has created the start-up company Idletechs to develop a technology that will make artificial intelligence more understandable for the rest of us.

C-sections by trained health officers a safe alternative

Sierra Leone has few doctors and even fewer surgeons to serve its seven million people. Since 2011, a non-profit group called CapaCare has been training community health officers to perform basic lifesaving surgeries. A new study shows the programme is working well when it comes to the most common surgery in the country — Caesarean sections.
