Clean water eliminated effects of discharged drugs in fish
The discharge of pharmaceutical drugs is a major problem around the world, but a new study of the freshwater fish burbot shows that there is hope.

What makes everyone sick?
The world’s best-known doctor is coming to the Big Challenge to talk about the world’s biggest challenge, and one that thousands of scientists are trying to figure out: what makes us sick? Norway is among the challenge participants.
Why you should care about better fibre optics
Fibre optic research can give us better medical equipment, improved environmental monitoring, more media channels – and maybe better solar panels.
Passion trumps love for sex in relationships
When women distinguish between sex and the relational and emotional aspects of a relationship, this determines how often couples in long-term relationships have sex. Passion plays a significant role.
How stores can throw out less food
Grocery stores throw out 75 000 tons of food annually. By adding date tagging to the barcode, food waste could be dramatically reduced, say two NTNU students.
How a black pig created an entire industry
Black Iberian pigs rooting for acorns under an idyllic grove of trees in a sunny landscape. This is the myth of the Spanish Ibérico ham.
How you can help the insect world
Many insect species are struggling. But all of us can help them, whether we live in an apartment or in a house with a garden.
Migrants are their country’s best and brightest
People who choose to emigrate are those with the best education, new research shows. This flies in the face of popular opinion.
Higher weight increases risk of psoriasis
The higher a person’s BMI, the greater the chance of getting psoriasis. But researchers are still uncertain as to why.
New nanomaterial to replace mercury
Ultraviolet light is used to kill bacteria and viruses, but UV lamps contain toxic mercury. A newly developed nanomaterial is changing that.
Reindeer adapt to climate change by eating seaweed
The arctic archipelago of Svalbard is already experiencing dramatic effects from climate change. A new study shows how these changes can force wild reindeer to graze on seaweed, a strategy that increases their likelihood of survival— and is recorded in their poop.
The women behind the periodic table
Textbooks and media can give the impression that the periodic table was the work of one man, but did you know that many of the contributors behind nature’s most important system were women?
What do the animals in stave church ornamentation signify?
The richly decorated portal at Urnes stave church has often been interpreted in light of paganism. That’s wrong, according to a new stave church study.
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.
Men sometimes act less interested in sex – in order to get it
In a new study, women said they acted a little more interested in sex than they really were. Men are the ones who apparently play cool most often.
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.
Kavli Institute researchers discover new type of brain cell
Researchers at NTNU’s Kavli Institute for Systems Neuroscience have found specialized brain cells that help us navigate in space.
Toss it if it’s 481 years old – but not if it’s a year older
Norway conserves archaeological finds from 1537, but not when they’re from 1538 or later. That means we know less about people’s everyday lives during the last 481 years.
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.
EU consumption results in high carbon emissions from tropical deforestation
A sixth of all emissions resulting from the typical diet of an EU citizen can be directly linked to deforestation of tropical forests. Two new studies shed light on this impact, by combining satellite imagery of the rainforest, global land use statistics and data of international trade patterns.
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.
