Cortisol is a steroid hormone made from cholesterol in the two adrenal glands above each kidney. It is best known for its role in the ‘fight or flight’ response and how, in stressful situations, it can increase the body’s energy production temporarily.
In the US, out of 5 million people living with Alzheimer’s, 3.2 million of these are women  and I thought that this was due to women living longer than men collectively but this gap between living ages of men and women is not substantial enough to be the whole story; Alzheimer’s is a disease that can last for as long as 20 years before the individual passes away and so the life expectancy of 5-8 years doesn’t add up. Continue reading “Why Are Women More Likely to Get Alzheimer’s?”
Norovirus is a stomach bug most common during winter time and is aptly named the ‘winter vomiting bug.’ It causes the deaths of 200,000 a year but this risk is limited to those that are immunosuppressed or the very young/old as they have trouble remaining hydrated.
The symptoms of norovirus appear after two days after infection and last for about the same amount of time. I would assume, in the same way that flu is a virus more common as we get closer to Christmas, norovirus is more stable in cold air and low humidity which allow the virus to remain in the air for longer, survive for longer, increasing the chance of a person inhaling the virus.

What do you think is the next biggest mankiller? Also, why do you think that men drink more than women? Happy Movember!

Prior to this blog post, the only female Nobel Laureate in chemistry that I knew of was Marie Curie and I didn’t know that there were any in the field of medicine. This may have just been my ignorance but now I know all of them and have been empowered because of it. Continue reading “Female Nobel Prize Winners in Chemistry and Medicine/Physiology”
Complex Regional Pain Syndrome was first described by Ambroise Pare who reported that after blood-letting King Charles IX, who had persistent pain. This fits into what can trigger the disorder: burns, cuts, surgical procedures, sprains. In the past CRPS was linked with the word causalgia which depicts a burning sensation.
About 1 in 3,800 people a year are diagnosed with CRPS and 7% of people who experience in one limb will later experience it in another limb.
It’s a miracle that women are able to form a person from a ball of cells which can then be pushed out of a hole that is tiny in comparison. Therefore, I decided to research what it is that makes this reproduction possible.
The story that all teenage girls are taught during sex-education classes is that women can give birth because they have wider hips and women that have slightly smaller hips are now more commonly told that they can’t have a natural birth or that their natural birth will be more laboured or longer in duration is slightly untrue.

Mitochondria are the organelles that release ATP, which is how energy is stored in living things and allows whole organisms, like the human body to function which is pretty impressive for such a microscopic (literally) body. In eukaryotic cells, usually cells that have a nucleus or other organelle such as a plant or animal cell but not bacterial cells, there are about 1,000 mitochondria in each cell and the knowledge we now have in the features and functions of the organelles are due to access to electron microscopy.
The discovery of mitochondria was in 1886 when Richard Altman used dye to identify, although Continue reading “Mitochondria- Nature’s Bank”
