Scientists have created a better way to see the brain chemical GABA. The new sensor, called iGABASnFR2, is brighter and faster than the first version. It can change its glow quickly when GABA appears, so researchers see signals more clearly. The team made many tiny changes to the protein.
The body’s first line of defense relies on sensors that detect danger signals. One such sensor, cGAS, normally lives in the cell’s fluid part but also shows up in surprising places such as the nucleus, tiny nuclear fragments called micronuclei, mitochondria, and even on the cell surface. When cGA
A group of kids at a school in eastern France recently spotted something odd beside their playground: a skeleton standing upright inside a shallow pit. This find adds to several similar bodies that have been unearthed in the city of Dijon, each positioned sitting with its back to an eastern wall and
In tropical regions, millions of people carry intestinal worms that can linger for years and cause serious health problems. When these worm infections overlap with malaria, the outcome is not simply additive; one disease can change how the other behaves inside the host. Researchers used mice to stu
The chikungunya virus has come back in some overseas areas of France and on the mainland, which worries health officials about a possible spread to French Polynesia. Scientists studied how people mix in the islands and found that certain patterns could let the virus travel more easily. For exa
Research papers sometimes give us conflicting answers about big questions like how Alzheimer’s disease starts in the brain. One paper suggests the APOE4 gene plays a key role, while another says it’s not a big factor at all. The problem isn’t that scientists disagree. The issue is that figuring out
People often wonder how photographers capture stunning images of nature’s hidden moments. One of the most impressive examples is a time-lapse showing a chicken embryo growing inside an egg. The person behind this eye-opening footage is a photographer who has turned tiny, fast-moving creatures into s
A loud explosion-like noise startled people in Cleveland and nearby states one evening. Many wondered if it was an accident or something else. Reports came in from as far as New York and Pennsylvania, describing windows rattling and walls shaking. Some residents thought an explosion had gone off nea
Sports aren’t just about competition—they can also change lives. Programs that use sports to teach teamwork, discipline, and health often struggle to prove their impact. How do we know if these efforts are really working? That’s where measuring success becomes tricky. A review looked at tools to tra
A bright streak across the morning sky startled people in Western Pennsylvania and parts of Ohio. The light, described by locals as a “daylight fireball, ” appeared at about 9 a. m. and was followed by a loud boom that made buildings vibrate. Scientists confirmed the event was caused by a small ast
