Making bike-sharing work

Bike-sharing is a way for cities to cut their greenhouse gas emissions while limiting urban congestion. But bikes have to be available when and where people want them. A new approach can help by ensuring bikes are in the right place at the right time.

Eavesdropping on whales in the high Arctic

The Earth’s oceans are crisscrossed with roughly 1.2 million km of fibre optic telecommunication cables — enough to girdle the planet 30 times. Researchers have now succeeded in using fibre in a submarine cable as a passive listening system, enabling them to listen to and monitor whales.

Better cyber security at sea

Drug dealers have tricked shipping cargo tracking systems to think drugs are “bananas” and unknown actors have jammed GPS signals in northern Norwegian waters. Fixing these problems requires understanding how seafarers themselves perceive cyber risks — so they can do a better job protecting themselves and their vessels.

Blocking the sun to control global warming

It sounds like something out of a bad science fiction movie — artificially blocking sunlight to keep global warming from overheating the Earth. Nevertheless, a small cadre of researchers is studying the option — so that if humankind ever needs to use it, it will be an informed decision.

Is it always right to save lives? A radical proposal

In neonatal medicine, there is a grey area where professionals may be uncertain whether it is in the child’s best interests to start life-saving treatment. Without it, the infant dies. But the treatment can also do great harm. One of the foremost duties of medicine is often said to be to “do no harm”. But how much of a burden on the infant is acceptable? At what point is the hope simply too small to justify action?

Icebreaker in ice

What kind of sea ice is that? Ask Knut!

A new app under development is using deep learning and artificial intelligence to classify different kinds of sea ice. People snapping photos during Arctic cruises and uploading them to the new app could someday help prevent Titanic -scale disasters.
