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.
There is a U.S. flag on the Moon, but in the future, countries may start to turn access to the Moon and asteroids into serious wealth.

Current trends suggest that powerful nations are defining the rules of resource use in space and satellite access in ways that will make it hard for developing nations to ever catch up.
Early Earth on the left, had seas infused with life-enhancing iron, whereas Earth today, seen on the right, does not.

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.
Traces of radioactive iron from the ocean floor, Antartica and the Moon reveal several waves of dust from distant stars over the past 10 million years.
From orange juice, to tea and coffee, to alcohol — different drinks can have different effects on iron absorption. This is worth thinking about if your iron levels are low.
The spread of tawny crazy ants may be driven, in part, by their need for calcium. The calcium-rich limestone bedrock of the lower U.S. Midwest may provide ideal conditions for populations to explode.
These compounds occur naturally in a number of healthy foods, including legumes and whole grains.

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.
Building renewable energy infrastructure involves mining for materials such as lithium, graphite and cobalt. If not done responsibly, that could cause huge environmental damage.
The food we eat influences our bodies’ immune responses to infection. So focusing on nutrition is one thing we can do to help protect ourselves in the face of the coronavirus threat.
Legumes are a good source of calcium.

The first step is to take an iron supplement to give your iron stores an immediate boost, then you want to investigate the cause and possibly work on your diet.
Furious winds keep the McMurdo Dry Valleys in Anarctica free of snow and ice. Calcites found in the valleys have revealed the secrets of ancient subglacial volcanoes.

Melting ice from Antartica could feed vast plankton blooms, trapping carbon in the ocean. To understand this complex mechanism, researchers looked at volcanoes deep under glaciers.
No, not that type of iron overload – haemochromatosis, when your body absorbs too much iron.
