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
Peptides and salts have a complex relationship. They play a big role in how our bodies work. Think of it like a dance. The way they move and interact changes based on their environment. One peptide, called melittin, was studied with different salts. These salts are part of a group known as Hofmeist
Scientists have found a way to make a powerful microscope work better with tiny drug particles in water. This microscope, called a scanning electron microscope (SEM), usually needs a vacuum to work, but it can also be used to look at things in liquid. The problem is, small drug particles and other o
Nothing, the tech company known for its unique designs, has unveiled its latest phone, the Phone 3. This device marks a significant shift for the company, as it ventures into the high-end smartphone market. The Phone 3 is priced at $799, putting it in direct competition with industry giants like the
Scientists have made a big leap in helping people who can't speak. They've created a brain implant that turns thoughts into speech right away. This isn't just about typing words on a screen anymore. It's about capturing the natural flow of speech, including tone and rhythm. For a long time, people
