Every swipe, click, and notification leaves a trace. Over years, these digital footprints add up to a hidden layer of health influences most people never consider. Researchers argue that the time we spend online isn’t just about entertainment—it actively rewires our biology and behavior in ways that
The goal of Safe and Sustainable by Design (SSbD) is to stop bad chemicals from hurting people before they become a problem. Scientists use a new way of looking at all the times we might be exposed to chemicals, called the life‑course exposome. By mixing these ideas, a new workflow has been cr
Genetic studies have shown that a person’s DNA can hint at their chance of developing cancer. Scientists now mix this genetic signal with information about a person’s environment and habits to create a single score that predicts risk. The idea is that both inherited genes and everyday exposures—like
A rare herb used in Chinese medicine has shown promise against a stubborn bird lung disease. Scientists focused on tiny particles that the plant releases, called exosome‑like nanoparticles. These particles carry a small RNA piece named miR159a, which can influence how cells respond to infectio
Scientists have built a new kind of tiny bubble that can sneak into stubborn bacterial layers and burn them away with light. The bubble is wrapped in a sugar shell made of hyaluronic acid, a substance that naturally appears in our skin. When the bubble reaches an infected wound, enzymes called hyalu
Scientists studied a way to help rats with brain damage that mimics human cerebral palsy. They used tiny packages called exosomes, which come from stem cells. These vesicles carry useful signals that can calm inflammation and support brain repair. The team gave the exosomes to rats that had suffere
Scientists use a special method called Hydrophilic Interaction Chromatography to sort molecules that are almost identical but mirror images. These molecules, called positional isomers, can be tricky because they behave almost the same yet need separate identification. The challenge lies in figuring
The Y chromosome has been a hot topic in science for a long time. Some experts think it might vanish, while others believe it will stick around. This debate is important because it makes us think about how life evolves. One scientist, Jenny Graves, said the Y chromosome has lost many of its genes o
Liposomes are tiny, fat-based bubbles that scientists use to deliver medicine. They are like tiny balloons made of the same stuff as cell membranes. These balloons can carry drugs inside them. This is helpful because it lets doctors send medicine exactly where it needs to go in the body. Making the
Melanoma, a tough-to-treat skin cancer, has been a challenge for doctors. It's aggressive and often resists treatment. But here's some good news: scientists have created a smart patch that could change the game. This patch uses tiny needles to deliver medicine right where it's needed. The medicine,
