Lakes are getting more and more algae blooms. This is a big problem. When algae die, they sink to the bottom. There, they rot and use up all the oxygen. This creates a bad environment for many creatures. But some worms, like Limnodrilus hoffmeisteri, can handle this mess. These worms burrow around,
Scientists have found a key protein in the sticky stuff that holds together sludge granules in seawater. This protein might be the reason these granules stay strong and can remove phosphate from water. The granules were grown in a special reactor using seawater and acetate, a common carbon source. T
Tiny plastic pieces, called microplastics, come in different shapes and types. Scientists wanted to see how these tiny plastics move through sand. They looked at two kinds: polystyrene (PS) and polyethylene terephthalate (PET). PS was in tiny spheres, while PET came in both spheres and fragments. T
A huge legal fight just ended quietly. Meta's big bosses, including Mark Zuckerberg, agreed to settle a case that could have cost them billions. Shareholders were mad about privacy issues that led to big fines. They wanted the leaders to pay up personally. But now, the trial is over, and no one is s
Scientists have created special tiny wires, called nanowires, that are really good at turning CO2 into useful stuff. These wires are made of two metals, palladium and copper, arranged in a unique way. The special thing about these wires is that they have tiny surfaces that are under stress, which ma
Ever wondered if machines can understand human emotions? Scientists have been working on this idea for a while. They used a special brain scanner called fNIRS to read emotions. This scanner is not like the big ones you see in hospitals. It is smaller and can be worn on the head. The study involved
Friction is a force that we feel every day. It is the reason why things slow down or stop when they slide. Scientists have known for a long time that friction between two dry surfaces does not change with speed. But what if there are many points of contact, and each one moves at a different speed? T
Brain-computer interfaces (BCIs) are like translators between our brains and machines. They need to be super accurate to be useful. But, using just one type of model to read brain signals isn't always the best. That's where hybrid models come in. They combine different types of models to get better
Coffee is a popular drink, but it can have a negative impact on dental work. Specifically, it can cause color changes and make the surface rougher over time. This is especially true for resin composites, a material often used in fillings and other dental treatments. Preheating is a common technique
Researchers have found a new way to shape semiconductor surfaces. They used a simple cracking method on GaAs substrates. This avoids expensive photolithography and etching steps. The method creates tiny, precise V-shaped grooves. The key is a thin layer of nickel. By changing its thickness, they co
