For decades, Americans were surrounded by lead from car exhaust, factories, paint, and even drinking water, often without realizing the damage it caused. By analyzing hair samples preserved across generations, scientists uncovered a striking record . ...

Arctic sea ice helps cool the planet and influences weather patterns around the world, but it is disappearing faster than ever as the climate warms. Scientists have now developed a new forecasting method that can predict how much Arctic sea ice will ...

New research suggests that Epstein-Barr virus may actively provoke the immune system in people with multiple sclerosis. Scientists found large buildups of virus-targeting immune cells in the nervous systems of MS patients, far more than in their ...

Researchers have discovered a previously unknown enzyme that plays a crucial role in fat production. By blocking it, they stopped weight gain, reduced liver damage, and lowered harmful cholesterol levels in animal studies. The finding opens the door ...

Inspired by the shape-shifting skin of octopuses, Penn State researchers developed a smart hydrogel that can change appearance, texture, and shape on command. The material is programmed using a special printing technique that embeds digital ...

Colorectal cancer has long baffled scientists because, unlike most tumors, patients often do better when their cancers are packed with immune-suppressing regulatory T cells. New research finally explains why. Scientists discovered that these T cells ...

Quantum computers struggle because their qubits are incredibly easy to disrupt, especially during calculations. A new experiment shows how to perform quantum operations while continuously fixing errors, rather than pausing protection to compute. The ...

Scientists at Keck Medicine of USC are testing an experimental stem cell therapy that aims to restore the brain's ability to produce dopamine, the chemical whose loss drives Parkinson's disease. The early-stage clinical trial involves implanting lab ...

New research using rhesus monkeys suggests that the brain's relationship with alcohol may begin forming long before a person ever takes a drink. Scientists found that exposure to alcohol before birth reshaped the brain's dopamine system, a key player ...

Scientists in Australia have uncovered a clever new way to fight some of the most dangerous drug-resistant bacteria by targeting a sugar that exists only on bacterial cells. By designing antibodies that recognize this unique sugar, researchers were . ...
