The thick and tangy history of ketchup
Have you ever thought about the history of ketchup? This tangy, sweet, slightly spicy condiment can add zest to any meal. But how did it become so widely loved, and how long has it been around?
How monsoons help clean up the air
Monsoons are intense storms that can cause flooding and bring strong winds and heavy rain in the southern U.S. However, they also clean the atmosphere by removing harmful particles and cooling the temperature. Have you experienced the benefits of monsoons on the air you breathe?
Is there an element lighter than hydrogen?
Scientists recently discovered an even lighter element than hydrogen, and it could revolutionize chemistry. This new finding challenges the previous belief hydrogen is the simplest element with just one proton and electron. So what does this mean for the scientific community as a whole?
The science of love
Love is a complex and intricate emotion. We all yearn for love, but the pain can be overwhelming when it’s lost. While it’s true that it originates in the chemistry of our brains, can science honestly explain love? Does it involve more than just chemical reactions?
Can you freeze your body and come back to life?
James Bedford was the first person cryogenically frozen after his death, way back in 1967. His hope was that someday advanced technology would enable him to be thawed and brought back to life. Was his optimism well founded? Will we ever achieve the capability to revive cryogenically frozen individuals?
Why we're losing so many satellites
A ton of new satellites were launched into orbit in 2022. Unfortunately, many of them were damaged by things outside of our control. Now scientists are left wondering, how do we protect satellites from harm and what’s responsible for the damage in the first place?
The surprisingly old tech airlines use
Recent winter storms caused chaos for airlines and passengers, with thousands of canceled flights and stranded travelers. Outdated IT systems were the real issue — not the weather. Why are airlines relying on such old systems?
Things that were discovered by accident
The path of science is often a slow one, taking years of research and effort to bring ideas to life. Every once in a while, luck strikes and something new is suddenly born. And you won’t believe it, but some of the most important inventions in history were actually discovered by mistake.
A day in the life of a stealth bomber pilot
You’ve probably heard of the U.S. fleet of stealth bombers and their reputation as some of the most feared airplanes in the sky. As tools of destruction, they’ve been striking fear into our enemies for years. Have you ever wondered what it takes to be a pilot of one of these beasts? It takes a lot more than just guts.
Does this Leonardo da Vinci invention actually work?
Leonardo da Vinci didn’t just create iconic artwork like the Mona Lisa and the Vitruvian Man. He was also a brilliant inventor, constantly sketching his wildest ideas in his notebooks. From a helicopter to a sound recorder, his sketches are nothing short of impressive. But imagine if someone brought one of those sketches to life today. Would it work?
Video doorbell solves murder, TikTok cancer scam, best apps for seniors
Plus, watch out for this dangerous app, three quick computer tricks, why vintage video games are making a comeback, the richest dog in the world and a weird new way to make money.
Why scientists are creating liquid robots
Robots assemble cars, fly planes and build tiny, complex machinery. But anything too small is tough because robots can only get so tiny. That’s why scientists are developing liquid robots made of liquid metal, capable of fitting anywhere. You won’t believe how this cutting-edge technology works.
Stealing baseball signs using machine learning
Baseball may seem like a maze of statistics and numbers, but one tradition remains a mystery — the hand signals a third base coach uses to indicate a steal. Imagine if a simple app could predict the runner’s next move. That’s exactly what one computer engineer tried to do.
The science of fun
The joy we experience when we’re having a blast is phenomenal! Our brains release a multitude of chemicals that make us want to repeat the fun activity over and over again. We’re not the only creatures who engage in play just for fun, either.
How trees control the weather
There’s nothing quite like the smell of the trees while you’re walking through the forest. The compounds that make up that smell do more than just smell good. Those molecules actually aid in the creation of clouds and play a huge role in weather patterns around the world. But how?
The history and insane engineering of modern submarines
When you think of powerful military weapons, you probably think of an aircraft carrier or a nuclear weapon. Don’t forget about the modern submarine, which is truly the behemoth of modern military strategy. The power behind these silent titans will blow your mind.
Recreating gecko skin for robots
Geckos can climb walls and hang from ceilings with ease. They do this without using any adhesive or fine hair, instead relying on their incredibly complex feet. These little creatures can grip flat surfaces and even support their entire bodies with only one toe. What if scientists could recreate these feet for use in robotics?
Controlling lightning using lasers
Humans have been using lightning rods to protect buildings and people from the devastating power of lightning for hundreds of years. But we still can’t defend things like airplanes and boats. Scientists are now trying a new technology to guide lightning to a safe place — and even to trigger lighting at will.
How they de-aged Harrison Ford for 'Indiana Jones' 5
The trailer for “Indiana Jones and the Dial of Destiny” is out and it’s turning a lot of heads. There are short glimpses of a young Harrison Ford, and it’s not archival footage. It’s actually a whole new CGI technology created just for this movie. But how does it work?
