The Proton Radius Puzzle May Have Been Solved

The Proton Radius Puzzle May Have Been Solved

Protons are the fundamental subatomic particles. Under the Standard Model, we know that protons are composite particles with three valence quarks, which, along with neutrons, form hardons.

The Search For Dark Matter Continues

The Search For Dark Matter Continues

Dark matter is one of the most fascinating concepts in physics and is thought to account for 85% of the universe’s matter. They have been so talked about that they have taken on a semblance of fact, even though at this stage their presence is purely hypothetical.

Understanding Quantum Primacy And How We Got There

Understanding Quantum Primacy And How We Got There

A quantum computer is a remarkable device. While, at current, it's still limited in its application, we now know that it can be faster than the fastest computers we currently have access to.

How Microbes Can Mine Rocks In Space (And How It Could Save Earth)

How Microbes Can Mine Rocks In Space (And How It Could Save Earth)

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.

Preserving The World's Biodiversity Outside Of Conservation Areas? It's Possible

Preserving The World's Biodiversity Outside Of Conservation Areas? It's Possible

Conservation areas have been one of the most successful methods for the modern world to ensure we preserve biodiversity. By declaring areas as protected, the biodiversity (both flora and fauna) is safe from hunting. Even in these areas, however, the problem of illegal hunting and poaching exists. Protected and conservation areas are the best attempt we currently have to keep the world's biodiversity alive.

From Diapers To Sticky Notes - A Revolution In Recycling

From Diapers To Sticky Notes - A Revolution In Recycling

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.

Correlation Between Underground Carbon Stores And Above-Ground Plant Biomass

Correlation Between Underground Carbon Stores And Above-Ground Plant Biomass

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.
