The ocean twilight zone could store vast amounts of carbon captured from the atmosphere – but first we need an internet of deep ocean sensors to track the effects

The ocean twilight zone could store vast amounts of carbon captured from the atmosphere, but first we need a 4D monitoring system to ensure ramping up carbon storage does no harm.

The ocean twilight zone could store vast amounts of carbon captured from the atmosphere – but first we need to build a 4D system to track what's going on down there

An ocean scientist describes plans for an ‘internet of the ocean,’ with sensors and autonomous vehicles that can explore the deep sea and monitor its vital signs.

Moon lacked a magnetic field for nearly all its history – new research resolves mystery sparked by rocks brought back on Apollo

Without a magnetic field, the Moon’s surface is exposed to solar wind. These could have been depositing resources like water and potential rocket fuel on the Moon’s surface for billions of years.

Anti-nutrients – they're part of a normal diet and not as scary as they sound

Anti-nutrients naturally occur in food and can block the amount of other nutrients available for your body to use. But their effects aren't all bad, which is why they're undergoing an image makeover.
