Causes of non-infectious diseases learning outcomes: Do non-infectious diseases cause more deaths than infectious diseases? According to the World Health Organization (WHO), non-communicable diseases (NCDs) such as heart disease, cancer, and diabetes, are responsible for approximately 71% of all deaths globally. Infectious diseases such as HIV/AIDS, tuberculosis, and malaria are responsible for approximately 25% ofContinue reading “Causes and effects of non-infectious disease”

Introduction to chemistry
We all want to make stuff. But, fundamentally we are just converting matter into more useful forms. That is what chemistry is all about understanding matter aka stuff so we can alter it to make our lives better. This introduction to chemistry is the first in our free interactive textbook to take you up toContinue reading “Introduction to chemistry”
Basic stoichiometry problems
Stoichiometry can be a tricky concept to grasp – but it shouldn’t be. The reason everyone gets stuck on it is because they treat the concept of a mole as a new concept. The mole is a unit of measurement used by chemists to communicate the quantity of chemicals they have. It is no moreContinue reading “Basic stoichiometry problems”
Chameleon Peptides: Changing themselves or pharma?
Chameleons change colour by using specialized cells in their skin called chromatophores. These cells contain pigments such as melanin and carotenoids. By expanding or contracting the chromatophores, chameleons can change their colour. This means they can change how they look in response to the environment. In a similar fashion there are a class of moleculesContinue reading “Chameleon Peptides: Changing themselves or pharma?”
Allotropes matter: A backbone breaking Carbon discovery
A recent discovery of a new carbon allotrope (E Meirzadeh, et al., 2023) has shaken the scientific community. It will have potential implications for the folks dabbling in the quantum computing realm 🖥️. But first, we have to be reminded more then we are taught: Allotropes are different forms of the same chemical element with differingContinue reading “Allotropes matter: A backbone breaking Carbon discovery”
Prevention of non-infectious diseases – HSC Biology
Understanding the prevention of non-infectious diseases, also known as non-communicable diseases is critical for HSC biology but more importantly for your well-being in general. Wisdom is having a long-term outlook. It is being able to identify the non-immediate consequences of immediate actions. That is why wisdom is prevention. Preventing non-infectious diseases is like playing a gameContinue reading “Prevention of non-infectious diseases – HSC Biology”
Is Jurassic world possible? Crispr, cloning and hybrids
Don’t worry we ain’t going to be dropping spoilers in here. But… After the success of Jurassic world dominion and it’s ability to capture the imaginations of the masses, we thought it would be a good idea to break down the science behind the cloning of humans and dinosaurs. After reading this the answer toContinue reading “Is Jurassic world possible? Crispr, cloning and hybrids”
History of acid and bases
Chances are you don’t know the history of acid and bases. You think just because you haven’t had to know about them before or you have forgotten about them, then they simply don’t matter all that much. Understanding the history of scientific discovery changes the way you see the present. It offers you a glimpseContinue reading “History of acid and bases”
Integral calculus questions and answers
Use these integral calculus questions and answers to make sure you go well on your exams. We often find our students can do these questions fairly fast and save a significant portion of time in the exam. You should see your accuracy improve significantly after completing 5 to 10 of these questions and marking yourContinue reading “Integral calculus questions and answers”
Perflubron Liquid breathing: Is it time to blow off air?
In second year of undergraduate, we walked into what we thought would be a standard anatomy class. But what we didn’t expect to see were to pairs of lungs open on the bench. One infant size. The other much larger. Much darker. The pearly white of the infants lung contrasted with the polluted adults lung.Continue reading “Perflubron Liquid breathing: Is it time to blow off air?”
