Four World Cup gold medals — and a baby

Marit Bjørgen was a world-class athlete at the top of her career — and then she decided to have a baby. How did that change her ability to train — and her performance afterwards?

Envisioning a future where all the trees in Europe disappear

Global climate change is already affecting the globe, as demonstrated by the shrinking polar ice cap, melting glaciers and cities in the grips of longer, more intense heat waves. Now a team of researchers has conducted a radical thought experiment on how extreme land use changes could influence future climate.

New study estimates the carbon footprints of 13,000 cities

Many see cities as the new front lines of the climate change fight. Identifying the mayors and city councils in cities with the biggest carbon footprints, and the most power to make big changes, could mobilize a wave of reinforcements.

Exploring new uses for existing antiviral drugs

Broad-spectrum antiviral drugs work against a range of viral diseases, but developing them can be costly and time consuming. Testing existing anti-viral drugs for their ability to combat multiple viral infections can help.

When a hole in the ice is a big problem

When your airport runway is located at 72 degrees south latitude and more than 4000 kilometres from the nearest major city, it better be in tiptop shape. But in Antarctica, where most runways are made of snow or ice, holes can be a big problem.

Land under water: Estimating hydropower’s land use impacts

One of the key ways to combat global climate change is to boost the world’s use of renewable energy. But even green energy has its environmental costs. A new approach describes just how hydropower measures up when it comes to land use effects.

Shedding light on zooplankton in the dark

We know that tiny marine creatures in the Arctic respond to weak light from the Moon or the northern lights during the polar night. Now researchers have learned that artificial light from research vessels can also have a negative effect.

How very low birth weight affects brain development

Children born with very low birth weights are at an increased risk of cognitive, emotional and behavioral problems throughout their lives. But what exactly happens in the brain to cause these problems?

Consumer choices for the climate

The gift-giving season is upon us, and perhaps you’re wondering how to give gifts that won’t wreck the climate. Help is on the way.

NOTES

Heat and efficiency in fuel cells

Hydrogen fuel cells can store and supply electricity, but are still developing as a technology. NTNU researchers are helping advance this approach to making the transition to environmentally friendly energy.

One hundred years of producing energy — from water

The 1969 discovery of oil at the Ekofisk field in the North Sea transformed Norway into an internationally important energy nation. But long before black gold was being pumped from the Norwegian Continental Shelf, Norway’s economy was fuelled by a different kind of energy: hydropower.

Controlling problem ice — by cracking it

Most efforts to control ice build-up on structures like wind turbines and solar cells involve creating a surface that repels water. But Norwegian researchers have engineered a different approach that allows ice to form on a surface, but then causes it to crack off.

Living with zero-emission technology

How does technology change people, and how do people change in response to technology? Sixteen people volunteered to live in a high-tech, zero-emission house to help researchers answer those exact questions.

Brewing Viking beer — with stones

When archaeologist Geir Grønnesby dug test pits at 24 different farms in central Norway, he nearly always found thick layers of fire-cracked stones dating from the Viking Age and earlier. Long ago, Norwegians brewed beer using stones.

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.

Finding life — and farming minerals — deep under the sea

Japanese researchers have access to the largest scientific vessel ever constructed, one that has a 120 metre tall derrick capable of drilling to 7500 metres below the seafloor. They’re using it to hunt for life deep under the seafloor and explore for mineral deposits at the bottom of the ocean — topics that are of great interest to Norwegian researchers.

VIEWPOINTS

Water reservoirs save lives and create value

While there is considerable opposition to dams and reservoirs in the Western world, reservoirs built to store water during the rainy season so it can be used during the dry season can save lives and secure values when the rains fail.

A force more deadly than polar bears

You might think that polar bears— and the potential for attack— are the biggest danger on the Norwegian island archipelago of Svalbard. But avalanches kill far more people on Svalbard than polar bears ever have.

Martin’s world

Visualizing oil reservoirs or tectonic plates under the seafloor requires lots of computing power and the imagination to envision what the data are showing you. That’s Martin Landrø’s work world. But he’s also fascinated by how teachers from a century ago taught their students about the Earth and the way it moves around the sun.
