The Wright brothers invented the first powered, sustained airplane in 1903. Their first plane was called the Flyer. How many horsepower did the plane have?
Despite its modest horsepower, the Wright Flyer made history on December 17, 1903, when it achieved the first powered, sustained, and controlled flight in Kitty Hawk, North Carolina. The flight lasted just 12 seconds and covered 120 feet (37 meters), but it marked the beginning of modern aviation. By the end of the day, the brothers had made four flights, with the longest lasting 59 seconds and covering 852 feet (260 meters).
Lake Natron is a hypersaline and highly alkaline lake located in East Africa. Most life cannot survive there. Which of the following fish can survive in the lake?
Did you know that Lake Natron's water is so caustic that it can burn the skin and eyes of most animals? Yet, the alkalinity tilapia not only survives but thrives here! This fish has evolved special proteins in its blood and unique kidney functions to handle the extreme alkalinity and salinity. It’s like a real-life "superfish" that defies the odds, making it a perfect example of how life can adapt to even the most extreme environments.
What is/was the Caspian Sea Monster?
The Caspian Sea Monster was a groundbreaking Soviet-era aircraft known as the Lun-class ekranoplan. It was a hybrid vehicle that operated as a ground effect vehicle (GEV), meaning it flew just above the surface of water or land, using the aerodynamic phenomenon called ground effect to achieve lift. This unique design allowed it to travel at high speeds while carrying heavy loads, making it a fascinating blend of an airplane and a ship.
Which of the following types of Keratin is the one found in human hair, nails, skin etc?
Keratin is one of the toughest biological materials in nature, which is why human hair and nails are so durable. In fact, hair is so strong that a single strand can support up to 100 grams (3.5 ounces) of weight! This strength comes from the disulfide bonds in keratin, which create a robust, cross-linked structure.

Due to the bone and vascular structure of owls they are able to rotate their heads about
If humans tried to rotate their heads as far as owls do, we’d likely cut off blood flow to our brains or damage our spinal cords. But owls can do it effortlessly, thanks to their evolutionary adaptations. This ability is especially useful for hunting, as their eyes are fixed in their sockets (they can’t move their eyes like humans can). Instead, they rely on their flexible necks to scan their environment and pinpoint prey with incredible precision.
These kinds of clouds are thought to form when there is significant instability in the atmosphere, often due to the interaction of two air masses with different temperatures and humidity levels. What is this type of cloud called?
Asperatus clouds are characterized by their undulating, wave-like appearance, often resembling a turbulent sea in the sky. Asperatus clouds are rare and were only officially recognized as a distinct cloud type in 2017 by the World Meteorological Organization.
Mice are used in human research because they have similar DNA to humans. What percentage of working DNA do humans share with mice?
Humans and mice share a surprisingly high percentage of their working DNA, also known as coding DNA or genes. Specifically, humans and mice share approximately 90% of their working DNA. This remarkable genetic similarity is one of the key reasons why mice are widely used in biomedical research to study human diseases, test drugs, and understand biological processes.
According to the Mayo clinic, coffee has a dehydrating effect on the body while tea does not.
It doesn't matter if you drink coffee or tea-it's the CAFFIENE that can cause dehydration. According to the Mayo clinic, consuming more than 500 milligrams of caffiene can cause dehydration.

An electrical outlet consumes power even when nothing is plugged into it.
An electrical outlet itself does not consume power when nothing is plugged into it, but certain devices or appliances that are left plugged into the outlet can still draw power, even when they are turned off. This phenomenon is known as "phantom load" or "vampire power."
According to a research study done at Beihang University in China, how fast can a woodpecker peck?
If a woodpecker's beak moves about 6 inches (15 cm) during each peck, and it pecks 20 times per second, the tip of its beak could reach speeds of around 15 mph (24 km/h). This is a rough estimate, but it gives you an idea of how fast and forceful their pecking motion is!
Can you tell the difference between a Jaguar and a Leopard? Which of the pictures below is a Jaguar?
1. Jaguar / 2.. Leopard
Mohair is a silky textile product that is considered one of the most luxurious fibers on Earth. What animal does Mohair come from?
Mohair, the luxurious and silky textile fiber, comes from the Angora goat. Despite the name, it’s important not to confuse Angora goats with Angora rabbits, which produce angora wool. Mohair is prized for its softness, sheen, and durability, making it a highly sought-after material for high-end clothing, blankets, and textiles.
