When we come across intriguing facts, such as the idea that our feelings of happiness can stem from endorphins produced by our central nervous system, we often overlook the scientists who spent years uncovering these truths. Let’s delve into some fascinating discoveries and the remarkable women who made them possible.
The Misinformation Effect highlights how our memories of events can become distorted over time, especially when new information interferes with our original recollections. A key figure in this field is American psychologist Elizabeth Loftus. In 1990, she provided expert testimony in a case where a woman recalled a childhood memory of a murder during therapy, which was the only evidence in the case. This led Loftus to explore whether vivid memories could be implanted through suggestion. In one study, she asked participants to remember getting lost in a mall as children. Astonishingly, 25% of them believed they had experienced this event, even creating detailed but false memories. Loftus has since testified in over 250 cases, significantly advancing our understanding of the unreliability of memory.
At the ends of our DNA strands are tiny structures called telomeres, which protect our chromosomes. Each time a cell divides, telomeres shorten, and shorter telomeres are linked to aging and mortality. In 1984, Australian scientist Elizabeth Blackburn was instrumental in discovering telomerase, an enzyme that repairs telomeres. Blackburn and her colleagues received a Nobel Prize in 2009 for this groundbreaking work. Her research has revealed that many illnesses, such as heart disease, are associated with shortened telomeres, potentially transforming our understanding of disease and aging.
By 2050, it is estimated that 1 in 85 people will be affected by Alzheimer’s Disease. However, promising research has shown that two molecules from a native Indian plant can alleviate Alzheimer’s symptoms and reverse brain plaque buildup. Indian scientist Vijayalaxmi Ravindranath conducted a study in 2012 demonstrating these effects in mice. Although this research is still in its early stages, it offers hope, especially since current medications are synthetic and only slow the disease’s progression.
We know that endorphins can lead to feelings of euphoria, thanks to American neuroscientist Candace Pert. In 1972, as a graduate student, she discovered the brain’s opiate receptor, where the body’s natural painkillers and endorphins interact with cells. This discovery has deepened our understanding of how our bodies manage pain and pleasure.

When you hear an interesting fact like “our euphoric feelings can come from our central nervous system producing endorphins,” you might not consider the scientists who dedicated years of research to make that discovery. In this video, we’ll explore the scientists behind these important findings.
The Misinformation Effect refers to how our recollection of events can become less accurate over time due to information received after the event interfering with our original memory. One notable figure in this area is American psychologist Elizabeth Loftus. In 1990, Loftus provided expert testimony in a case involving a woman who recalled a childhood memory of a murder, which was uncovered during therapy and served as the sole evidence in the case. This prompted Loftus to investigate whether vivid memories could be implanted through suggestion. In one of her studies, she asked participants to recall a time they got lost in a mall as children, and 25% of them came to believe they had genuinely experienced that event, even creating detailed memories that were not part of the discussion. Loftus has since testified in over 250 cases, contributing to our understanding that memories are not as reliable as we might think.
There are small structures at the ends of our DNA strands called telomeres, which protect our chromosomes. Each time our cells divide, telomeres shorten, and over time, shorter telomeres are linked to aging and mortality. In 1984, Australian scientist Elizabeth Blackburn played a key role in discovering telomerase, an enzyme that repairs telomeres. Blackburn and her colleagues were awarded a Nobel Prize for this discovery in 2009. Her research has shown that many illnesses are associated with shortened telomeres; for instance, individuals with heart disease tend to have shorter telomeres compared to those without the condition. This discovery may change how we understand illness.
It is predicted that by 2050, 1 in 85 people will be affected by Alzheimer’s Disease. However, research has shown that two molecules derived from a native Indian plant can alleviate symptoms of Alzheimer’s and reverse plaque buildup in the brain. Indian scientist Vijayalaxmi Ravindranath conducted a study in 2012 that demonstrated these effects in mice. While this research is still in its early stages, it offers hope, especially since current medications are synthetic and only slow the progression of Alzheimer’s.
Additionally, we understand that the production of endorphins leads to feelings of euphoria because American neuroscientist Candace Pert discovered the brain’s opiate receptor in 1972 as a graduate student. This receptor is where the body’s natural painkillers and endorphins interact with cells.
