All over social media, there are articles discussing radio signals from other galaxies and stellar systems. The number one rule in astrophysics and cosmology is - IT IS NEVER ALIENS. A lot of radio signals can be interpreted and can have natural sources; rapidly rotating neutron stars, supermassive black holes and so on. So how … Continue reading Extraterrestrial Contact Series Part 1 – The Wow! Signal.

Since the first use of penicillin in 1942, antibiotic resistant bacteria have started to evolve. Usually, resistance develops quickly (a few years after drug introduction). This means that bacterial infections that once were benign could become deadly (back to how bacterial infections were prior to antibiotics). However, there are a few plans that could help … Continue reading How can we combat antibiotic resistance?
Surgery is a growing field. New technologies and methods for carrying out procedures are constantly evolving, making surgery much more safer and result in higher success rates. However, in the past, this wasn't at all the case. All aspects of medicine weren't as advanced and were completely different, including surgery.

Viruses can harm us, one example being COVID-19. This is because viruses can not replicate or live by themselves. So they insert themselves into host cells (our cells) and use the host’s organelles and machinery to replicate. Once replicated, they burst out of the cell by cytolysis, killing the cell in the process. As a … Continue reading How viruses help kill bacteria.
Your body needs to be able to regulate its water levels to prevent cells from getting damaged. Due to osmosis, if your body has too much water, your body cells will swell up and burst. On the other hand, if your body doesn’t have enough water, cells will shrivel up and die. Thankfully, as a … Continue reading The Kidneys and Controlling Water Levels
What are telomeres? Telomeres are caps at the end of our chromosomes that protect our DNA from damage. They are made up of the same short DNA sequence repeated over and over again, with the same sequence of bases. They are important for a cells because without them chromosomes would stick together and would not … Continue reading Telomeres and why we age.

However, there a numerous disadvantages to these traditional vaccines: They … Continue reading Vaccination delivery through a pill.
There are three types of radiation: alpha (α), beta (β) and gamma (γ) radiation, which all have different properties due to their structure. Radiation is emitted from radioactive isotopes (isotopes are different versions of the same element with the same number of protons but a different number of neutrons, so they have the same atomic … Continue reading The Three Types of Radiation
