The science of ‘stuff’, Chemistry seeks to understand what things are made of, and how these constituents behave. This involves studying the interactions between atoms and the larger structures they form, predicting further interactions, and deriving practical applications of this knowledge.

Due to the highly versatile nature of carbon and the way it interacts with the other elements, chemistry is traditionally divided into three main subdisciplines. The first is organic chemistry: the study of molecules built around a framework of carbon, hydrogen and oxygen atoms. The second subdiscipline is inorganic chemistry, which is the study of all of the remaining chemicals and their interactions. Finally, physical chemists crunch numbers to analyse the inherent properties of chemical reactions and apply the laws of physics to chemical phenomena. These three subdisciplines overlap, combine and are applied to many different fields to produce a range of branches impacting on practically every aspect of the world around us.

We've published 17 articles and 25 specialist blog posts about chemistry so far, featuring 340 unanswered chemistry questions! But we're not done yet as there are still plenty of ongoing chemistry research areas to write about, so come back soon!

“Ice Age Mars” –Challenges a Once ‘Warm and Wet’ Red Planet
3rd August, 2020
  “Mars once was wet and fertile. It’s now bone dry,” said Cosmos host, Neil deGrasse Tyson, “Something bad happened on Mars. I want to know what happened on Mars so that we may prevent it from happening here on Earth.” Mars is crisscrossed with distinctive tracks of big, long-dead rivers but scientists still don’t […] The post “Ice Age Mars” …

New Zealand wants to build a 100% renewable electricity grid, but massive infrastructure is not the best option
30th July, 2020
Janet Stephenson, University of Otago A proposed multibillion-dollar project to build a pumped hydro storage plant could make New Zealand’s electricity grid 100% renewable, but expensive new infrastructure may not be the best way to achieve this. New Zealand’s electricity generation is already around 80% renewable, with just over half of that provided by hydro power. The government is …

Entropy
Entropy or disorder, is a scientific measure of things spreading out, of uncertainty, or of the information required to describe something. Entropy always increases, so what impact does it have on our universe, our materials, and our concept of exist

Pregnancy
There are many unknowns when it comes to pregnancy, and many accepted phenomena are still unexplained, or simply attributed to "hormones" or "the placenta" (a complex and poorly understood organ!)

Plastics
What happens to plastic when it gets disposed of into the environment, and how might it affect us?

If a keystone species is lost, the entire ecosystem can collapse.

Particles
On scales too small to see are weird and wonderful particles. Their bizarre properties make up the world around us, yet we hardly know a thing about them!

Extraterrestrial life
The search for alien life catches many people's imagination and has always been a very public branch of science. So with all this investigation, why has our search revealed nothing? Are we truly alone in the Universe?

Vision
Vision is arguably a human's primary sense - we use it to spot danger and navigate our environment. Despite this, there is still plenty we don't know about how this sense works.

Senses
Our senses allow us to explore and interact with the world around us. Even the simplest living organisms have some way to sense their environment - and some animals can sense in ways we can't even imagine!

Vaccines
There are many open questions surrounding vaccines – but perhaps not the first questions that come to mind. Vaccines do not cause autism, but there are many things we don’t know about them, such as why some wear off.

Microbiome
The ecosystem in your gut – how the microbiome might affect what we eat, what illnesses we get and whether we gain weight easily. How to change your microbiome and why it's such a fuzzy business.

Pain
Pain, while unpleasant, is vital for our survival. But in many cases it can get out of hand, and limit people's activity and quality of life. More needs to be understood about pain before we can develop ways to help people with chronic conditions.

Smell
Smell is probably the least well understood of our five main senses, despite playing a huge role in our lives and impacting our well being more than we realise.

Immune system
Our immune systems are vital for our survival as they protect us from bacterial, viruses and other pathogens that could cause us harm. But sometimes, they can go wrong, and cause damage to our bodies.

Water
Water is vital for our survival, but how much do we really know about it?

Thermodynamics
Thermodynamics is very successful at describing the way energy interacts with itself and matter – but every now and then a paradox will pop up, or someone will spot an event which no one has an explanation for yet.

Climate change
Scientists agree that human activities are causing climate change, but the finer details are still unknown.
