The First Kill and the Conquest of Outer Space 413

When I watched "2001: A Space Odyssey" for the first time, directed by Stanley Kubrick, I must have been around 12 to 14 years old. Obviously, I understood absolutely nothing. I watched it driven purely by my affinity for science fiction, more specifically for the theme of space. However, when I watched it again almost 20 years later, already graduated as a biologist, I arrived at an understanding of the first act that I believe few people have had. At least that was my perception, since none of the people I spoke to about it saw the connection that I am about to present. There is a striking scene in the film that I call “The Cut”: the abrupt transition from the first to the second act, in which an ancestral primate of humankind, holding a bone, throws it into the air, and the camera follows the bone as it rises until the director cuts to a space station in a future time. The message I perceived was that, at the moment these hominids began to consume meat, since before that they gathered seeds, ate roots and vegetables alongside herbivorous animals, there was a significant change that, in my view, represented an evolutionary leap. When an individual noticed the skeleton of an animal, there was a long, robust bone, probably a femur. He picked up this bone and began to manipulate it until he discovered that it could be used as a weapon. Wisely, the director alternates scenes of this individual testing the new weapon with scenes of him killing an animal that lived among them, followed immediately by scenes of them feeding on the meat of that slaughtered animal. We know that, among all sources of protein, meat has the highest protein content in the diet, and it is very likely that this increase in protein intake in the diet of our ancestors enabled an increase in brain mass and, consequently, an increase in cranial volume. This can be observed by comparing skulls of other closely related primates, such as chimpanzees, gorillas, and orangutans, and even fossil skulls that have been found. This difference is evident, allowing us to conclude that this was what propelled us evolutionarily in relation to our relatives within the primate order. It is clear in the scenes that, in addition to using the bone as a tool to kill prey, it was also used as a weapon to attack other groups or to defend against them, since behavior related to dispute and conquest has always been part of our construction as a biological species. And what is the relationship between all of this and the famous “cut” at the end of the film’s first act? It is that, at the moment our ancestors began to feed on meat, a process of brain enlargement began, which led to an increase in intelligence, an essential condition that would later make possible the conquest of outer space, as shown in the abrupt cut from the scene of the bone being thrown into the air to a space station in orbit. Well, this was my free interpretation of that important moment in the film. For this reason, I invite everyone to take a careful look at the messages that are conveyed, whether in films, songs, or works of art in general. The author has the need to communicate something through their art.

What is the most expensive liquid on Earth? 6805

Imagine a liquid so precious that just a small droplet could be worth more than a diamond. This isn’t a scene from a science fiction story; it’s reality, and the liquid is scorpion venom. Scorpion venom is potentially the most expensive liquid on Earth, with prices soaring to millions of dollars for just one gallon. But what makes it so incredibly valuable? Scorpions, those small, often feared creatures, carry in their tails a venom used for defense and hunting. Extracting this venom is a meticulous and often hazardous task. Specialists must carefully ‘milk’ the scorpions, a process that involves stimulating the scorpions to release their venom, which is then collected drop by drop. This labor-intensive method, combined with the venom’s scarcity, drives its high cost. But the price tag is not just due to the danger and difficulty of extraction. The real treasure of scorpion venom lies in its composition and potential to revolutionize medicine. Scorpion venom is a cocktail of numerous compounds, including peptides and proteins, each with specific effects. For instance, chlorotoxin, found in the venom of the deathstalker scorpion (Leiurus quinquestriatus), shows promise in targeting cancer cells, making it a beacon of hope for new cancer treatments. Another component, called scorpine, has been studied for its antimicrobial properties and its potential to combat malaria. Researchers are intrigued by how these compounds can lead to breakthroughs in drug development. Imagine a new kind of painkiller derived from scorpion venom that could offer relief without the side effects of current medications, or innovative treatments capable of combating autoimmune diseases and even halting the spread of cancer. These are not just hopeful speculations but real possibilities being explored in labs around the world. The process of transforming venom into medicine is complex and involves identifying and isolating the active components, understanding their mechanisms of action, and then synthesizing them in forms suitable for medical use. Despite the challenges, the potential health benefits drive scientists and pharmaceutical companies to invest in this research. This intricate dance of danger, rarity, and medical promise makes scorpion venom more than just an expensive liquid; it’s a symbol of the incredible potential hidden in nature, awaiting discovery. In a world where answers to some of our biggest health challenges might be found in the most unexpected places, scorpion venom stands as a testament to the wonders of the natural world and human ingenuity’s boundless curiosity.
