In the world of medicine, tiny tools are making a huge difference. Scientists are using super-small technologies to fight diseases and deliver medicines in smarter ways. These tiny tools, called nanotechnology, are like tiny robots that can target specific parts of the body. This means medicines can work better and cause fewer side effects. But that's not all. Scien...
Our brains are like sneaky editors. They don't just show us what's out there. They tweak it, sometimes without us even knowing. Ever seen something out of the corner of your eye and then questioned if it was really there? You're not alone. Scientists have been trying to figure out how much our brains mess with what we see. In one experiment, people were shown a qui...
Kissing is a universal behavior seen in many species, from humans to animals like wolves and polar bears. Recent research suggests that this act of affection has been around for a very long time, dating back to around 21. 5 million years ago. Scientists believe that the common ancestor of humans and great apes likely engaged in kissing, and even Neanderthals may have...
Cancer is a tricky puzzle. Scientists have been using a special tool called the Reactome Graph Database to understand it better. This tool helps them see how different genes work together in the body. They looked at 862 genes that cause cancer and 324 genes that cause other diseases but often show up in cancer patients too. These genes are like players in a big game...
Neanderthals have always fascinated scientists, especially their unique facial features. One big question has been why their noses stuck out so much. Some thought it was because they lived in cold places, but a new study says that might not be the whole story. Deep inside a cave in Italy, there's a Neanderthal fossil called the Altamura Man. This fossil is super wel...
Creating new drugs is tough and expensive. Right now, scientists use flat cells or animals to test drugs, but these methods don't always work well for humans. That's where new tech comes in: tiny, 3D versions of human organs, called organoids, and special chips that mimic how organs work. These tools could make drug testing better, safer, and faster. Organoids are l...
When winter arrives, ice becomes a common problem. To tackle this, people often use ice melts. Two popular choices are calcium chloride and sodium chloride. Both work by lowering water's freezing point, but they do so in different ways. Sodium chloride, or rock salt, is widely used. It disrupts the hexagonal structure of ice, preventing it from forming. However, it'...
Deep inside a cave in southern Italy, a remarkable discovery has been made. The Altamura Man, a Neanderthal fossil trapped in rock, has given scientists their first-ever look at a Neanderthal's nasal cavity. This is a big deal because these delicate bones usually don't survive in fossils. Researchers used special technology to study the nasal cavity without even tou...
Aluminum has always been a popular choice for making things light and strong. But what if it could be even stronger? That's where single-walled carbon nanotubes (SWCNTs) come in. These tiny tubes are incredibly strong and have a large surface area, making them perfect for reinforcing materials. The challenge has always been mixing these tubes with aluminum. Old meth...
A comet named 3I/ATLAS has been making headlines since its discovery on July 1, 2025. This comet is special because it's only the third interstellar visitor we've seen in our solar system. But what's really got scientists buzzing is its strange behavior near the sun. It's speeding up in a way that gravity alone can't explain, and it's glowing with a bright blue light...
