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.
So what is “gand” sorcery – really?

Improving occupational safety in aquaculture
Aquaculture used to be a secondary income source for Norwegians. Now it’s become big business. Occupational safety has made steady advances, but some areas clearly still need to improve.
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.
Small birds discern threat level of enemies
Small birds like tits don’t just see that another bird is dangerous. They can also differentiate between species and determine just how much of a threat they are.
Women regret sex less when they take the initiative

Predicting the fate of oil spills in a frozen world
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?
Acclaimed fossils might not depict human evolution
Humans may have evolved relatively recently from isolated chimpanzees, without formation of any fossils. This would mean that since the time of Darwin, the missing-link fossils that people have been looking for simply do not exist.
