ケダモノペニス

When it comes to evolution, the drive to reproduce is one of the most powerful forces in animal penis design. Nowhere is this more evident than in the diversity of reproductive organs found across the animal kingdom. From barbed structures that induce ovulation to corkscrew designs that fit only a specific mate, the adaptations in the animal penis are as varied as they are strange. These bizarre shapes and mechanisms aren’t just for show—they serve specific functions to help species overcome obstacles to reproduction, ensuring that sperm reaches its intended target, that competing males don’t stand a chance, and that offspring have the best odds of survival. In this article, … 続きを読む

The natural world is a realm of astonishing beauty and wonder, where countless species engage in intricate dances of survival and reproduction. However, hidden within the realms of nature’s tapestry lies a darker, more gruesome side to the process of procreation. Across various taxonomic groups, some animals display mating rituals that are nothing short of horrifying, where the pursuit of mates takes on a disturbingly violent and even cannibalistic turn. In this exploration of horrifying mating rituals, we delve into the realm of arachnids and insects and the depths of the ocean, where males resort to drastic measures to secure their lineage. From the chilling act of traumatic insemination in … 続きを読む

Tool use, once considered a hallmark of human uniqueness, has emerged as a fascinating aspect that bridges the gap between humans and animals. Long celebrated as a defining feature of human evolution and civilization, the skillful use of tools has proven to be an adaptive strategy employed by both humans and select animal species. From our early ancestors crafting primitive stone tools to modern humans harnessing sophisticated technologies, the significance of tools cannot be overstated in shaping human progress. Yet, in recent decades, observations of tool use in certain animals have challenged the notion of human exceptionalism, revealing intriguing similarities and distinctions between our species and the natural world. This … 続きを読む

According to 50 leading scientists, human-caused global warming has continued to rise at an “unprecedented rate” since the most recent major assessment of the climate system was published two years ago. Global Warming and the Paris Agreement The goal of limiting global warming to 1.5 degrees Celsius above pre-industrial levels is outlined in the Paris Agreement, a global effort to combat climate change. Achieving this goal requires significant reductions in greenhouse gas emissions and widespread adoption of renewable energy sources. While progress has been made in recent years, the Intergovernmental Panel on Climate Change (IPCC) has warned that the world is not currently on track to stay below the 1.5-degree … 続きを読む

Algorithms in ancient times When you think of algorithms, you’re probably thinking of Wall Street supercomputers whizzing around making thousands of calculations and transactions in a fraction of a second or social media companies monitoring your every click and comment, targeting you with ads and polarizing content. The concept of an algorithm however, has been in use by humans for thousands of years in various forms such as instructions for performing tasks, solving problems and making decisions. Ancient civilizations, such as the Greeks and the Babylonians, have used algorithms in their mathematical and construction practices. Euclid, a Greek mathematician, described the Euclidean algorithm for finding the greatest common divisor of … 続きを読む

With World Bee Day coming up, let’s take a closer look at one of the most fascinating bee species on the planet: The killer bee. Origins of Africanized honey bees While their cousins are know to help police catch serial killers, Africanized bees prefer to do the killing themselves. In the 1950s, Brazilian researchers attempted to breed a more productive and disease-resistant honeybee by crossing a European honeybee with a subspecies of African honeybee. This resulted in the creation of Africanized honeybees, also known as “killer bees,” a hybrid species of honeybee. The goal was to create a bee that would be better suited to the subtropical climate of South … 続きを読む

The world may soon be infested with serial killers. As we all know, honey bees play a crucial role in catching the likes of Jeffrey Dahmer, Ed Gein and more. If we don’t act now, the serial killers will prevail. All joking aside, honey bee lifespans are 50% shorter than they were fifty years ago. This decrease in longevity in lab-kept honey bees may be to blame for recent declines in honey production and colony losses. Honey bees’ lifespan decreased by 50% A new study by entomologists at the University of Maryland reveals that the lifespan for individual honey bees kept in a controlled, laboratory environment is 50% shorter than … 続きを読む

If you’ve been bingeing Netflix’ serial killers series and you’re worried you might be living next-door to another Jeffrey Dahmer, you need not worry; he or she probably won’t pick you as their next victim, at least according to science and the study of the humble bumblebee. In order to track down and catch serial killers, police use algorithms created by studying bumblee behaviour. What’s the link? Bumblebees and serial killers have something in common, even if you don’t think so: Both prefer to stay close to home and don’t like to share their address. Now, it might be possible to locate the other by studying their routines. Geography based … 続きを読む
