An AI assistant was supposed to help solve a difficult coding problem, but Google Gemini reportedly ended up doing something far stranger. After repeated failures, the chatbot began describing itself as a failure and eventually repeated the phrase “I am a disgrace” dozens of times. The bizarre exchange quickly attracted attention because Gemini’s language sounded …
A baby tooth can preserve more than a childhood memory. New research suggests that these tiny teeth may also contain clues about long-term exposure to hundreds of chemicals during some of the earliest stages of development. A small pilot study from The University of Texas at San Antonio Health Science Center found significantly higher concentrations …
Alan Alda’s first sign of Parkinson’s disease looked nothing like the symptom most people associate with the condition. Before he experienced the familiar tremors or other movement problems, the actor discovered that he was physically acting out his dreams while asleep, including one incident in which he threw a pillow at his wife. The 90-year-old …
A baby facing a potentially dangerous lung tumor received treatment before birth, giving doctors a chance to reduce the pressure on the developing heart and lungs. The procedure used a thin needle and microwave energy while the baby was still inside the womb. The treatment was performed at 22 weeks of pregnancy after scans showed …
Imagine a single vaccine that could protect you from virtually any type of cancer. Scientists at the University of Florida have taken a bold step toward making that vision a reality. Their newly developed mRNA-based vaccine shows the potential to train the immune system to recognize and destroy cancer cells, regardless of where they appear …
The dream of restoring sight to the blind has long been one of medicine’s most ambitious pursuits. For decades, researchers have searched for ways to bypass the damage caused by retinal diseases such as age-related macular degeneration (AMD) and retinitis pigmentosa, which gradually destroy the photoreceptor cells responsible for capturing light. These conditions rob millions …
Every food choice carries consequences. Some build health. Others chip away at it, minute by minute, meal by meal, until years vanish from expected lifespans. Researchers at the University of Michigan wanted exact numbers. Not vague warnings about unhealthy eating or general advice to choose better foods. They needed precise calculations showing how many minutes …
Two-thirds of the world carries the herpes simplex virus type 1. Most people know it as the source of painful cold sores around the mouth. Few would imagine it could save lives. Scientists at Keck Medicine of USC took HSV-1, stripped away its ability to cause disease, and transformed it into a weapon against advanced …
For centuries, humanity has regarded aging as an inevitable process, a gradual, almost poetic unraveling of life’s fabric. From wrinkled skin to weary hearts, the passage of time seemed an internal affair, a private conversation between cells and their slow decline. Science, too, has followed this intuition, seeking aging’s root causes in the microscopic breakdown …
A discovery that began with a single-celled alga has now earned the 2026 Nobel Prize in Physiology or Medicine. The breakthrough gives researchers an extraordinary way to switch specific nerve cells on and off using light, allowing them to study the brain with a level of precision that was previously out of reach. The technique, …
You can feel perfectly healthy and still have changes happening inside your arteries that you cannot see or feel. A major international study has now found signs of silent atherosclerosis in surprisingly young adults, including people who had no known cardiovascular disease and no obvious symptoms. Researchers examined 16,808 adults between the ages of 18 …
Gray hair is usually one of the clearest signs that our bodies are changing with age. New research, however, suggests that those silver strands may also reveal something much more complicated about the way our cells respond to damage. A study from researchers at the University of Tokyo has uncovered a surprising connection between hair …
