Sea urchins are often enjoyed fresh, but what happens when they're left at room temperature? Scientists decided to find out by studying two types of sea urchins, Strongylocentrotus nudus and Strongylocentrotus intermedius. They kept them at a cozy 25°C (that's about 77°F) with some humidity for 48 h
Bayesian statistics is a powerful tool for making sense of data. It helps us understand the uncertainty around our estimates. But what happens when our models are not perfect? This is called model misspecification. In such cases, Bayesian posteriors may not accurately reflect the true uncertainty. M
Bacteria and our bodies are in a constant battle. One sneaky bacteria, Simkania negevensis (Sne), has found a way to mess with our body's defense system. This bacteria causes respiratory diseases and hides inside our cells. It has tools to break down our body's defenses, but scientists are still fig
Innovation doesn't just happen by chance. It often starts with the right environment. Groups, big or small, play a big role in making this happen. They can create spaces where new ideas can grow. But how exactly do they do this? First, groups can bring people together. When different minds come tog
Esophageal fistulas, or holes in the esophagus, can happen due to cancer, injuries, or medical treatments. These fistulas can cause serious problems, and while metal stents can help block them, they can also cause issues like migration or bleeding over time. A new kind of stent has been created to
In the world of materials science, there's a new kid on the block that's causing quite a stir. This isn't your average material; it's a fibrous aerogel that's as light as a feather and tough as nails. Imagine a material that can handle temperatures hot enough to melt most things, yet is so light it
Scientists have been experimenting with different materials to help bones heal better. They've created a new type of material that combines calcium phosphate with tiny amounts of sodium, magnesium, and zinc. This mix is then heated to a high temperature to make it strong. They also added a ceramic
Air pollution is a big problem. Factories, cars, and cities are pumping out nasty gases like NO2, NH3, and H2S. These gases are bad for people and the planet. To fight this, we need good gas sensors. These sensors act like guards, alerting us when pollution levels get too high. One type of sensor t
Robots are now helping doctors treat tumors in a tricky spot behind the throat. This area is called the parapharyngeal space. Doctors use a special kind of robot surgery called TORS. It lets them operate through the mouth. This is less invasive than cutting through the neck. A recent study looked a
Insects can be a big problem. They spread diseases. Scientists have a plan. They want to use radiation to sterilize them. Then, release them into the wild. This is called the sterile insect technique (SIT). The goal is to reduce the insect population. A special machine was tested. It's called the P
