You've probably heard about tiny nanoparticles being used to fight bacteria. But what happens when these nanoparticles, like zinc oxide (ZnO) and titanium dioxide (TiO₂), end up in our rivers and lakes? Scientists wanted to find out how they might affect rainbow trout. They exposed the fish to these
Imagine you're a police officer in a tactical group, facing the toughest and riskiest situations. Your heart rate (HR) is usually what's measured to see how hard you're working. But there's another tool that might be better at showing your overall stress level – heart rate variability (HRV). This st
Some federal health agencies have temporarily stopped sharing certain information, like updates on food outbreaks and flu vaccinations. This pause is part of a wider communication break ordered by the Trump administration. It gives the new team time to set up their own way of sharing important healt
Imagine a giant magnet helping to clean wastewater from farms. A team of scientists crafted a clever system using magnets to tackle a big problem: wastewater loaded with antibiotics. The system they designed, called the MC-IFAS, uses magnets to boost the cleaning power of tiny living things in the w
Imagine you're following the story of antibiotic resistance genes as they travel through a wastewater treatment plant. These genes, both inside (intracellular) and outside (extracellular) of bacteria, have different fates. When wastewater arrives at the plant, it carries a mix of these genes. Some a
Trace Cyrus penned an emotional open letter to his father, Billy Ray Cyrus, after his performance at Donald Trump's Liberty Inaugural Ball. The letter highlighted Trace's deep concerns about Billy Ray's health. Trace recalled idolizing his father growing up and feeling disconnected from him now. He
Ever thought about the power hidden in complex networks? They're not just dots and lines; they carry a wealth of information. But analyzing these networks can be tricky, especially when they come with diverse details about nodes and edges. Existing methods often struggle with this complexity. So, l
The Arctic's Hudson Strait is experiencing some big changes due to climate change. It's getting warmer, rivers are discharging more water, and sea ice is melting faster than ever before. This means the area stays ice-free for longer during the summer. Scientists decided to check out the tiny microbe
Scientists in Australia just made a stunning discovery. They found a special protein in the blood of Sydney rock oysters that can kill bacteria and make our current antibiotics work better. This is a big deal because bacteria are getting smarter and tougher, leading to what experts call a "looming g
The future of aging might look a lot different with the help of AI. University students think so too, especially when it comes to using AI service robots in places where older adults live, like long-term care homes. These homes already face staff shortages, and that's where AI robots like Aether cou
