Cracking the code to sea cucumber farming
Sea cucumbers are internationally known as a superfood, as they contain many healthy substances. They are highly sought after by both Chinese restaurants and health food manufacturers. However, many sea cucumber species are threatened with extinction, so researchers want to farm them commercially – on land.
Video games do not lead to, or increase, ADHD
Children with ADHD play more video games than other kids do, but gaming does not cause or worsen the condition. Nor do electronic games cause anxiety or depression.
A revolution in vaccine development – but will we all benefit?
By manipulating the “instruction manuals” that control cell function in our bodies, we will soon be able to combat many diseases, including the new coronavirus outbreak. However, in the worst scenario, such innovations will only benefit the rich.
Instagram makes it easier to exercise
People who followed researchers’ motivational posts on Instagram got more enjoyment out of their training sessions. Just a couple of minutes over the course of four weeks was enough to make a difference.
Is your child getting enough sleep?
Children who get the least sleep have the greatest risk of developing mental health issues.
Abandoned cropland helps make Europe cooler
As nations prepare to mitigate climate change, decision makers need to understand how land use fits into the climate equation. A new study looked at land use changes over two decades and found a major shift from cropland to forests. That change made western Europe cooler.
China’s rapid development of solar and wind power
Chinese authorities are investing heavily in green energy. The country has become a world leader in solar and wind power. This rapid expansion was made possible by the approach taken by authorities.
Preparing ourselves for extreme events
As wildfires raged through the Swedish forests in 2018, a new set of European resilience management guidelines for dealing with crises was demonstrating its potential usefulness to decision-makers. Applying these recommendations can save many lives and protect major infrastructure assets during cross-sectoral accidents and crises.
Following sea trout minute by minute
Sea trout populations have declined sharply. Researchers have studied the life of sea trout by means of acoustic telemetry tags and listening stations. Now they know more about what we need to do to protect the sea trout population.
Your sewage is valuable muck
A world without phosphorous is a world without life. But phosphorous is a finite resource, so researchers are recovering it from sewage.
A new thermal insulation bag will save lives
It is very likely that the human body develop hypothermia following an accident. Maintaining a patient’s body temperature on the way to hospital can be crucial to survival. The prototype of a new and improved solution is now ready.
State’s large investments smarter than many people think
From the press coverage, you might expect only wasted time and projects built over budget when the government invests in roads, buildings and other large projects. But the state — in Norway, anyway — doesn’t do a bad job after all.
More people and fewer wild fish lead to an omega-3 supply gap
Omega-3 fatty acids are essential components of healthy diets for both humans and fish. The dramatic increase in fish farming worldwide has boosted the demand for omega-3 fatty acids so much that today’s supply can’t meet demand. Reducing waste and finding new sources can help.
PAI – a training tool to keep you young
Research from NTNU is now being integrated into millions of smartwatches worldwide. You work on a single training goal, and the fitness tracker tells you if you reach that goal. It may be the key to staying healthy.
Fitness calculator can reveal a lot about your health
NTNU’s Fitness Calculator was developed in 2013. It was able to reveal your body’s real age and how long you could expect to live. Now it turns out that it can tell you much more about your health.
Vision may be the real cause of children’s problems
Do you have poor motor skills or struggle to read, write or solve math problems? Maybe it’s really because of how your brain interprets what it sees.
The most beautiful solar cells are inspired by nature
Organic solar cells are usually less effective than silicon solar cells. But there is still a market for them – and they’re beautiful and exciting.
Your plane travel destroys polar bear habitat
A group of polar bear researchers wants you to do more than worry about the fate of these beautiful animals. They’ve calculated how much summer sea ice is melted per metric tonne of CO2 emissions. Then you can decide if the flight you’re planning to take is worth destroying polar bear habitat.
Diabetes prediction tool overestimates risk and creates unnecessary anxiety
The FINDRISC questionnaire has been used extensively to predict a person’s degree of risk for getting type 2 diabetes, but new findings show that it does not adequately identify the most vulnerable individuals.
Making beer super fast from ancient Norwegian yeast
The distinctly Norwegian beer-brewing yeast kveik reduces fermentation time drastically. That’s a huge advantage, according to NTNU PhD candidate Christian Schulz.
Making future transport more climate friendly
The world’s transportation network is constantly growing. “Green asphalt” and sustainable bus transportation will ease the environmental impact of future transport routes.
New mechanism allows the immune system to detect and respond to HIV
Nearly 40 million people were living with HIV in 2017, the UN says, with just over half taking antiretroviral therapy. These drugs have cut AIDS-related deaths by more than half since the 2004 peak, but the disease cannot be cured. A new mechanism uncovered by a Norwegian research group could improve the chances of developing one.
Ocean acidification a big problem — but not for coral reef fish behaviour
Several high-profile studies report that ocean acidification will affect coral reef fish behaviour enough to jeopardize their survival. One research team looked more deeply at this assertion — and found it is simply not true.
