Scientists have been working hard to improve targeted drug delivery by using the acidic environment in tumors. They focus on changing the active sites of drugs, like hydroxyl groups, to enhance stability, lower toxicity, and boost how well the drug hits its target. But the problem lies in making the
Imagine trying to measure something tiny, like the ions in your body, but your tools aren't good enough. That's what scientists have been dealing with. They need better ways to track ions inside living things, and current tools just don't cut it. They're too big, too stiff, and can't monitor multipl
Ever wondered how doctors quickly check for liver and heart diseases? Scientists have been busy creating a special tool called a biosensor. This sensor measures the amount of a key protein called aspartate aminotransferase (AST) in your blood. AST is like a signal that something's wrong in your hear
A tiny molecule called (E)-2-Hexenal, or E2H, plays a big role in how ripe fruits are and how long they last. But there aren't many easy ways to detect this molecule. A group of scientists has come up with a clever solution: a color-changing sensor. This sensor uses a special material that changes c
Ever considered how powerful it can be to have someone who shares your perspective on life? Research has shown that this shared reality can make life feel more meaningful. Uncertainty is a part of life, but with a partner who understands your view, that uncertainty can fade. Studies on couples, thos
Imagine if robots could feel and sense the world around them like humans do. That's what scientists have been working on with a new flexible sensor. This sensor is like a tiny, smart patch that can detect pressure, temperature, and even magnetic fields. It's made of a flexible coil on a polyimide ba
Eleven months after Ingenuity, a helicopter on Mars, made its last flight, engineers and scientists from NASA and a private company involved in its creation have found the probable cause of its crash. The problem? The chopper's sensors didn't see enough detail on Mars' smooth surface to figure out i
Ever wondered how your ankle stability might be related to what's happening in your brain? A recent study dug into this question. Researchers looked at people with chronic ankle instability (CAI) and those without it. They asked both groups to do a simple foot exercise called dorsi-plantarflexion, w
In the world of biosensing, enzymes often struggle with stability and efficiency. They can easily break down, and the substances they work on may decompose before the job is done. Scientists have found a clever way to fix this by trapping two essential enzymes, glucose oxidase and horseradish peroxi
Ever thought about how ants and plants hang out together? It's all about mutual benefit. Some plants make sweet treats called extrafloral nectaries (EFNs) for ants. In return, ants guard the plants against hungry critters. But what happens when it gets hot? A study in Brazil's Caatinga dry forest fo
