MazeMap navigates the world

The map app started by getting students where they needed to go in Trondheim. Now MazeMap is showing people the way on five continents.

Bigger people will need more food

Food demand is growing as people get bigger. Feeding a population of 9 billion in 2050 will require much more food than previously calculated.

World’s tiniest circuit takes shape

Components are falling into place for the technology of the future. They can provide smaller, faster and cheaper electronics with minimal energy consumption.

Geoengineering, other technologies won’t solve climate woes

The countries of the world still need to cut their carbon dioxide emissions to reach the Paris Agreement’s climate targets. Relying on tree planting and alternative technological solutions such as geoengineering will not make enough of a difference.

Are smoking genes to blame for drinking, too?

Some smokers have genes that predispose them to heavier smoking. Researchers looked at whether those same genes might trigger heavier drinking — and it turns out, they don’t.

When 80 microns is enough

Should you care that scientists can control a baffling current? Their research results could someday affect your daily living.

How plants respond to attacks

Plants have to defend themselves against drought, enemies and disease. But different threats demand different responses. So how do plants know what’s attacking them?

Norwegian public asked to name a species

The moss world will never be the same. The moss Norwegian researchers thought they knew has played a trick on them. In return, researchers are calling on the Norwegian public to name a new species.

Raising better salmon

The aquaculture industry typically selects salmon with the right genes for breeding to provide the freshest and biggest fish. A new method has the potential to produce better results.

Boys still lag behind in reading

When boys start school, they recognise fewer letters and their corresponding sounds than girls do. The difference is just as great at the end of the school year.

In the bullfinch world, she gets to decide

A lot of birdwatchers like the bullfinch. They’ve probably noticed that the female can chase off the more colourful male from the bird feeder. That makes this species different.

Are you at risk for lung cancer?

No, this question isn’t only for people who’ve smoked a lot. Seven factors, including two new ones, can predict whether you have a high risk of developing lung cancer.

Vampire bats’ bloody teamwork

Vampire bats are the only mammals that feed exclusively on blood. The way they manage to do that offers us some remarkable insights into evolution.

What the Vikings put in their pillows

Not too many people are able to identify birds by examining a single feather. But a number of folks need to know that sort of thing, and it can actually save lives.

Is the woolly mammoth really gone for good?

Should we reintroduce animal species that have died out? New technology may offer opportunities that no one could imagine a few decades ago. But the answer may not be as simple as you think.
