A “health centre” for juvenile salmon
The condition of the water in salmon hatcheries can tell us a great deal about when and why outbreaks of disease occur. Now, SINTEF researchers are about to expose the water’s secrets, both to prevent suffering in fish and to save the aquaculture industry a great deal of money.
Infidelity can be forgiven – but at a cost
Most people who have been unfaithful do not believe it when their partner says they forgive them. And the fact that men often don’t realize that emotional infidelity is a problem just feeds the conflict.
This ingenious approach not only binds CO2, but also improves the soil
If 4,000 Norwegian farms and nurseries produced biochar and mixed it with the soil, we could halve CO2 emissions from the agricultural sector. This entirely natural approach also produces more robust and healthy plants.
How can people and predators coexist?
Predators and people have lived side by side since time immemorial in the Serengeti National Park region in Tanzania. But strong population growth is leading to greater conflicts.
Why aren’t house sparrows as big as geese?
A group of researchers spent twelve seasons making some house sparrows bigger and others smaller. Their experiment yielded some important answers.
The enigma of early Norwegian iron production
Ancient Norwegians made top-quality iron. But where did the knowledge to make this iron come from? An NTNU professor emeritus may have solved this riddle.
Gunnerus Sustainability Award goes to pioneering researcher
Carl Folke, a groundbreaking researcher in his field, has been awarded the Gunnerus Sustainability Science Award for 2017.
What happens at home also comes to school
The relationship children have with their parents can sometimes influence the relationship they have with their teachers. Now we know more about why.
Reveals the real greenhouse gas footprints of reservoirs
When hydropower reservoirs traps organic matter, it leads to higher local greenhouse gas emissions. But the emissions are not increased but displaced. A new tool calculates the real greenhouse gas footprints of reservoirs.
Stress in the nest can have lifelong effect
Why do some sparrows hatch six chicks while others don’t hatch any? How does upbringing affect the remainder of their lives? Physiological stress in the nest can actually affect birds’ DNA and possibly their lifespan.
Human Evolution in the Sea at Bioko
Did some of our human features evolve while our ancestors were living in water? The aquatic ape theory has been disregarded by paleoanthropologists, but it deserves another chance.
Avian songsters
Bird songs have many functions, but their main purpose is to attract a mate. Some of the best avian singers are described below.
The astronaut’s extra nose
How do we protect astronauts in space from breathing dangerous gases? A German-Norwegian hi-tech optical gas sensor provides a solution.
Snake robots in space
Norwegian researchers are investigating how a snake robot might carry out maintenance work on the International Space Station (ISS), study comets, and explore the possibility of living and working in lava tunnels on the Moon.
Fuel of the future
Heavy-duty trucks will soon be driving around in Trondheim, Norway, fuelled by hydrogen created with solar power, and emitting only pure water vapour as “exhaust”. Not only will hydrogen technology revolutionize road transport, it will also enable ships and trains to run emission-free.
Earth to ISS: Norway calling
Norway has direct contact with the ISS space station. Now CIRiS – the Centre for Interdisciplinary Research in Space – is opening a new control room.
Norway leads the way in CO2 capture
This week, scientists from all over the world meet in Trondheim to learn about the technology of CO2 capture.
Astrophysics a field for great discoveries
As a child, Professor Myrheim wondered what the far side of the Moon looked like. Trondheim’s Starmus festival will welcome a trio who has actually been on the moon, and the astrophysicist is excited to hear their lecture. “Perhaps it’s the magic of childhood that lingers on,” he says.
Moonwalkers three
Just 12 Americans have set foot on the lunar surface, and of those, only six are still alive. Three—Buzz Aldrin, Charlie Duke and Harrison “Jack” Schmitt — will be in Trondheim at the Starmus Science Festival to talk about the future of humankind in space.
Two prestigious awards for research on interfaces
Two international professional organizations recognize PhD research that could improve everything from weather forecasts to the prediction of volcanic eruptions.
Climate change, ocean diversity and women in science
Science has made great strides since Svante Arrhenius, the Swedish Nobel Laureate who in 1896 first determined that carbon dioxide from human activity could warm the planet. The same progress hasn’t been made in increasing the number of women in the sciences.
Award-winning science communicator “not surprised” that Trump pulled out of Paris climate agreement
This year’s winners of the Stephen Hawking Medal for Science Communication 2017 were announced yesterday at a press conference in New York. The winner of the science communicator award is astrophysicist Neil deGrasse Tyson. The medal itself will be awarded on 20 June during the Starmus Science Festival in Trondheim.
Will send a giant sunflower into space
Imagine a firefly fluttering near a floodlight. Can you see it? Not unless you shade the light coming from the glare of the lamp. This is where the sunflower screen enters the picture.
