Clear braces are a popular choice for straightening teeth. They are made from different materials. But how do they hold up under heat and cold? A recent study looked into this. It tested three types of clear aligner materials. The goal was to see how heat and cold cycles affect their strength. Firs
Ever wondered how scientists tell one monkey species from another? It's not as easy as it sounds. Rhesus macaques, often used in research, share their homes with other primates. This makes it tough to identify them just by looking at hair or poop samples. The problem? These species look alike, and s
Genetic research is crucial for understanding human health. Yet, not everyone is eager to join these studies. A recent study looked into why some people, especially those from diverse backgrounds, are hesitant to take part. The study involved over 2, 000 people from different ethnic and racial back
Alzheimer's disease is a complex puzzle. One key piece? Tiny powerhouses in our cells called mitochondria. These little guys usually help cells stay alive and healthy. But in Alzheimer's, they're not working right. Why? Because calcium, a crucial messenger in cells, is out of balance. Calcium is li
In the world of tiny creatures, the Pacific oyster, Crassostrea gigas, has a clever way to protect itself from harmful microbes. It uses a special protein called CgC3 to tag and trap invaders. This protein can stick to various sugars and microbes, acting like a sticky note that marks the bad guys fo
People need certain things to live well. Things like homes, hospitals, schools, and fun places. But not everyone can get to these easily. Some people live close to them. Others have to travel far. This is a big problem. A recent study looked at this issue. They made a big list of places that give t
Freezing stuff without damaging it is a big deal. Think about ice cream. If it melts and refreezes, it gets all grainy. Now imagine that happening to cells or even organs. Not good, right? Scientists have been working on ways to freeze and thaw things without causing damage. They've come up with som
Viruses are everywhere. They are the most common living things on our planet. Yet, we know very little about them. A new project called VIRE is changing that. It is like a big map of viruses from all over the world. This map includes over 1. 7 million viral genomes. These genomes come from more than
Polymer science is making waves in health tech. Imagine gadgets that stick to your skin, heal themselves, and even break down safely. These are not sci-fi ideas but real advancements in plastic bioelectronics. Unlike old-school silicon tech, these new devices are soft, stretchy, and bendy. They fit
Lithium-sulfur batteries are a big deal. They can store a lot of energy, but they have a problem. The stuff inside them, called lithium polysulfides, moves around too much. This makes the batteries wear out faster. Scientists are trying to fix this by making better catalysts. These are like helpers
