How Phosphorus Boosts Nickel-Iron's Oxygen Evolution

Scientists have long known that nickel-iron catalysts are great at producing oxygen from water, especially in alkaline conditions. But how they do it so well was a mystery—until now. A recent study looked at a special catalyst, nickel-iron phosphide (NiFeP), which is super active and stable. It only

Understanding and Managing Complicated Bacterial Infections in the Blood and Heart

Gram-positive bacteria, like Staphylococcus aureus, Streptococcus, and Enterococcus, are commonly behind bloodstream infections and heart inflammations. "Complicated bacteremia" is a term doctors use for S. aureus infections that spread to other parts of the body. This requires longer treatment and

Why Biliary Tract Cancer is Often Caught Late

Biliary tract cancer, or BTC, starts in the bile ducts inside the liver (intrahepatic cholangiocarcinoma), the main ducts near the liver (extrahepatic cholangiocarcinoma), or the gallbladder (gallbladder cancer). Because symptoms are often vague and there are no routine screenings, most patients don

TriFocal Lens: Seeing Near, Far, and In-Between

Everyone dreams of perfect vision. But what if a lens that promises just that also comes with some downsides? Let's talk about the PanOptix trifocal intraocular lens (IOL), which is designed to give clear vision at all distances — near, intermediate, and far. It's great for tasks like reading, worki

From Einthoven's Discovery to Modern Heart Health: A Century of Progress

A hundred years ago, Willem Einthoven changed the way we understand our hearts. He was awarded the Nobel Prize for figuring out how to read the heart's electrical signals, a process we now call electrocardiography. This method lets us see the heart's activity on the body's surface, which is pretty a

Unleashing the Power of Chiral Phosphorus: A New Way to Make Complex Molecules

Imagine trying to build a complex, three-dimensional structure using specific building blocks. That's what scientists do when they create chiral phosphorus compounds. These molecules have a specific shape, much like a left or right hand. Although methods to craft these structures exist, their true p

CsCuCl3 Microcrystals in Solar Fuel Production

We all know that lead-based metal halide perovskites are great at converting light into electricity. But they're also toxic, which holds them back from wider use. What if there's a safer alternative? Scientists have been exploring a series of perovskite microcrystals called CsCuClxBr3-x. This time,
