Proving the universe seems like a gargantuan task, but we might have a chance to do so with exascale computers.

Mining is a messy process. It takes a lot of effort to break open rocks to get the materials needed to keep our current technological level on earth. The march of technology has produced some massive leaps and bounds in communication and quality of life improvements. However, most of these are predicated on the availability of difficult-to-find elements.

Earth shifted from an anaerobic atmosphere to an aerobic one early in its life. However, for a long time, the question as to how it got there was still unresolved.

Diapers are not what you'd think about first when you consider recycling. The CBC estimates the number at billions of disposable diapers entering landfills in North America. With this much waste, recycling these absorbent plastics might seem like a good idea. The super-absorbent material inside diapers is made up of long-chain polymers. Unfortunately, they don't get put into recycling bins because the composition of these materials is too complex to break down and recycle traditionally. The problem with diapers is that we haven't found a way to recycle them into something useful. At least, until now.

Do we have a nitrogen emergency? Most people aren't aware of the role nitrogen plays in our atmosphere. According to NASA, Nitrogen makes up about 78% of our atmosphere. Despite being so prevalent, we give it relatively little thought. We've spent years worrying about carbon dioxide and its impact on the environment that nitrogen has slipped by relatively unbothered. Yet nitrogen pollution is a significant enough problem to demand attention from the United Nations.

One of the things that scientists rely on to accurately predict climate change is the amount of carbon sequestered underground. Carbon dioxide in the air leads to increased global warming, exacerbating climate change. When plants have a lot of access to carbon dioxide, they photosynthesize more. Scientists have assumed for a long time that this led to a high concentration of carbon sequestered under the ground. As plants took in this carbon dioxide, they transformed it into compounds and organic structures such as roots and leaves, which would add to the amount of carbon stored underground.
