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.
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.
For the first time ever, researchers have been able to peek deep into the mantle of the Earth under an ultraslow mid-ocean ridge, where they have been able to observe mantle melting and growth of the Earth’s crust.
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.
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.
Twenty-five years ago, African wild dogs (Lycaon pictus) disappeared from Serengeti National Park. A firestorm of debate followed when one researcher claimed that handling by scientists was the cause. New research refutes that claim and offers another explanation.
Climate change in the Arctic means more winter rain, and consequently more rain falling on snow. The result can be a buildup of ice under the snow, which can wreak havoc with arctic ecosystems.
As much as 20 per cent of jet fuel burned in Norway in 2030 could be biofuel made from the country’s forest residues. This alone could cut greenhouse gas emissions from Norway’s aviation sector by 17 per cent.
Our carbon emissions are much higher than are needed for us to have happy, healthy lives. But cutting these emissions requires us to think differently about how we measure growth and progress.
Even the most basic moves in life, like getting out of bed in the morning, require far more coordination than one might think. Neuroscientists may have just uncovered key aspects of how the brain controls body posture during these kinds of everyday movements.
The oceans are teeming with ever-increasing numbers of jellyfish. These squishy sea creatures can ruin fishing and discourage tourists. But one research group wants to turn this nuisance into pay dirt.
Lakes choked with algae and marine “dead zones” result from too many nutrients in the water. The traditional culprit is agriculture, which relies on fertilizer to boost plant growth. But the production of consumer goods, like clothing, is also a major — and growing — contributor.
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?
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.
A new database gives researchers — and potentially policymakers — the ability to see how global trade affects environmental impacts.
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.
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 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.
Excess CO2 in the atmosphere is making the oceans more acidic. Some studies show that’s bad news for fish, including commercially important species. But not all fish respond the same way.
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.
May-Britt Moser and Edvard I. Moser have been awarded Norway’s Grand Cross of the Order of St. Olav.
If you want to be as fast or as strong as the world’s most decorated female winter Olympian ever, you’ll have to train a lot — more than 900 hours a year. But don’t worry — most of that training will be low intensity.
Global warming and political decisions are opening the Arctic and its frosty seas to increased development. But what will happen if that expansion results in oil spills in the frozen ocean?
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.
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?
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.
The secrets of St Olav’s shrine and Nidaros Cathedral have drawn pilgrims for nearly a thousand years. Curious researchers have also made the journey, eager to solve the mysteries locked up in the cathedral’s stones.
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.
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.
A series of first-ever maps shows regional-scale differences in carbon footprints in the EU. The maps can help guide local and regional policies designed to cut greenhouse gas emissions.
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.
