This fundamental study combines in vitro reconstitution experiments and molecular dynamics simulations to elucidate how membrane lipids are transported from the outer to the inner membrane of ...

“You can see these gray wells — they’ve been abandoned,” said Rob Klenner, a former oil and gas engineer who is now GreenFire’s chief executive, pointing to a diagram of the site where ...

The other way to keep nitrogen in the ground is fertiliser. Keeping this cycle going in a sustained manner is what organic agriculture has been about for the last 11,000-odd years. Composting ...

Recent research from the Eve Appeal showed that half of women aged 26-35 were unable to label a diagram of the vulva ... changes over the menstrual cycle. How do you keep this fluid factory ...

This is especially true in the Arctic Ocean, where geographic and climatic factors contribute to a particularly complex nitrogen cycle. Arrigo et al. review current knowledge of how nitrogen ...

But that nitrogen influx has disrupted Earth’s natural nitrogen cycle. Today, nitrogen pollution is causing overshoot of several planetary boundaries. Nitrates pollute waterways, causing ...

But how can agriculture affect the nitrogen cycle? How has it managed to reach a breaking point? To feed the world, isn’t intensive agriculture best? Let’s take stock of the situation.

In its reactive forms however, it becomes accessible and creates impacts at each stage of the nitrogen cycle, moving through the air into the soil and living organisms. Molecular nitrogen (N 2) is ...
