How we conquered the deadly smallpox virus
10,000 years ago, a lethal virus emerged in northeastern Africa. This airborne virus targeted the skin cells, bone marrow, spleen, and lymph nodes of those infected. Symptoms included high fevers, vomiting, and rashes, with a mortality rate of 30% among sufferers during the second week. Survivors were marked by lifelong scars and scabs. This was the advent of smallpox.

AN ARTIFICIAL HEART
Imagine going to bed with a backpack. Today I bring you the most famous historical event that happened for 555 days time would dare to be this guy for even a day. Would you dare playing basketball on an Artificial heart. Let's dive in fellows: This guy named Stan Larkin, a 25-year-old Michigan resident, lived 555 days without a human heart transplant.(How stunning is this). He carried a gray backpack with a power source for an artificial heart pumping in his chest. In November 2014, Larkin's real heart was removed from his body and replaced with a device that allowed him to stay home instead of in a hospital while waiting for a transplant. Human organs grown in pigs may help transplant patients, and the total artificial heart finally arrived in May 2016. Larkin recovered from his procedure at the University of Michigan Frankel Cardiovascular Center and returned home the following week. In 2016, there were about 4,000 patients nationwide waiting for human heart transplants, and many of these patients have weak hearts that could cause critical organs to fail while they are waiting.

Voyage Through the Cosmos: From Our World’s Pale Blue Dot to the Physical Limits of the Universe
# Exploring the Cosmic Scale: From the Earth to the Observable UniverseIn the vastness of space, our beautiful planet the Earth is placed at a very unique position. From the perspective of space science, dramatic reality begins as one moves ‘out there’ into the galaxy and the universe. The Earth as referred to by Carl Sagan as the ‘pale blue dot’ is the background against which all human actions unfold. From this cosmic dust, and without any more preamble, we set off through distances defining our solar system and the universe beyond. In case of the solar system, the closest entity to us is the moon and its average distance is approximately 384000 Kilometers. To put this distance into perspective, imagine driving at a speed of 100 kilometres per hour for over 160 days to get to our moon companion. The observers are left with the impressions of how small the place to live is and that it is endangered with extinction when observing the Earth from the Moon. Farther away we have the Sun—the star that provides light and heat—at a distance of approximately 150 million meters or about one astronomical unit (AU). The time taken by the light to get to the Earth from the Sun is 8 minutes and 20 seconds, which makes one appreciate the size of the solar system. Not only is the sun the source of life in this planet but also the point of reference when searching for the rest of the universe. Mars is the fourth planet of the solar system and the distance between it and the Earth varies due to Mars’ elliptical movement around the sun. Even at its nearest position, Mars is a mere fifty-four million miles from the earth. So, the average distance from the sun reaches 6 million kilometers while the maximum distance is 401 million kilometers. If each area were to move as fast as a commercial airplane, then a trip to Mars will take decades, arguing about the challenges of space exploration.

Understanding Discomfort: A Psychological Experiment
Understanding Discomfort: A Psychological Experiment Imagine being asked to put your hand into a bucket of cold water. Sounds simple, right? Now, imagine you have to keep it there for an unknown duration while rating your discomfort on a scale. This is part of an experiment replicating a study by Daniel Kahneman and Barbara Fredrickson from 1993, investigating how we perceive and remember discomfort. Participants were told that the experiment aimed to compare pain perception between the dominant and non-dominant hands. But that wasn't the true purpose. The real focus was on how the participants would recall their experience of pain. Participants submerged one hand in 14°C (57°F) water for 60 seconds. They were asked to rate their discomfort in real-time, describing sensations like stinging, aching, and numbness. After the trial, they took a 15-minute break and then repeated the process with the other hand. What the participants didn't know was that the two trials were different. One trial ended after 60 seconds, while the other continued for an additional 30 seconds with the water warming slightly to 15°C (59°F). This slight increase in temperature reduced the discomfort, but it was still uncomfortable. The big question was: Which trial would they prefer to repeat? Surprisingly, most participants preferred the longer trial, even though it involved more time in discomfort. In our small-scale replication, seven out of twelve people chose the longer trial. In the original study, about 70% preferred it. This seems odd, right? Why would anyone prefer more discomfort? It turns out our brains play a trick on us. Kahneman and Fredrickson found that our memories of experiences are shaped by two key moments: the peak (the most intense part) and the end. This is known as the peak-end rule. To understand this better, Kahneman and his colleagues conducted another study. They showed students short and long versions of pleasant and unpleasant videos. They found that the length of the video had little effect on how positively or negatively it was remembered. Instead, the most intense and the final moments had the biggest impact. This concept of duration neglect means that the length of an experience doesn’t affect our memory of it much. What matters are the peak moments and the ending. For example, if a vacation has a few really great days and ends on a high note, you'll remember it fondly, regardless of how long it was. This idea also applies to negative experiences. If a medical procedure ends with a period of less discomfort, patients are likely to remember the whole experience more positively. In a 2003 study, Kahneman tested this with colonoscopy patients. Those who had an extra three minutes of less painful discomfort at the end rated the experience as less unpleasant and were more likely to return for follow-up procedures. This phenomenon extends to everyday life. For instance, if you finish a workout with a pleasant cool-down rather than a tough sprint, you’re more likely to remember the workout positively. Similarly, if you end a shopping trip with a treat, like a cheap hot dog at Ikea, the whole trip feels better. Even significant life events are influenced by the peak-end rule. A study showed that people rated a shorter life ending at 30 as more desirable than a longer life ending at 35, if the extra years were less fulfilling. The ending heavily influences our perception of the entire experience. Understanding this can help us create better memories. To make vacations more memorable, focus on having a few peak experiences and ending on a high note. In day-to-day life, ending activities with something pleasant can improve our overall perception. This insight isn't just an interesting psychological quirk; it has practical applications. It can improve our health, relationships, and overall happiness by helping us create better memories. In conclusion, our perception of experiences is shaped more by key moments and how they end than by their overall duration. By focusing on creating strong positive peaks and pleasant endings, we can enhance our memories and make life more enjoyable.
