Scientists at Stanford Medicine have discovered a treatment that can reverse cartilage loss in aging joints and even prevent arthritis after knee injuries. By blocking a protein linked to aging, the therapy restored healthy, shock-absorbing cartilage ...

Researchers report that vagus nerve stimulation helped many people with long-standing, treatment-resistant depression feel better--and stay better--for at least two years. Most participants had lived with depression for decades and had exhausted ...

Scientists have uncovered why people with chronic kidney disease so often die from heart problems: damaged kidneys release tiny particles into the bloodstream that actively poison the heart. These particles, produced only by diseased kidneys, carry . ...

Researchers have identified a key molecular interaction that accelerates Parkinson's disease by damaging the brain's energy systems. They designed a new treatment that intercepts this harmful process, protecting brain cells and restoring their ...

Quantum computers could revolutionize everything from drug discovery to business analytics--but their incredible power also makes them surprisingly vulnerable. New research from Penn State warns that today's quantum machines are not just futuristic . ...

After the Big Bang, the Universe entered a long, dark period before the first stars formed. During this era, hydrogen emitted a faint radio signal that still echoes today. New simulations show this signal could be slightly altered by dark matter, ...

Astronomers have captured the most dramatic view yet of a planet losing its atmosphere, watching the ultra-hot gas giant WASP-121b for an entire orbit with the James Webb Space Telescope. Instead of a single stream of escaping gas, the planet is ...

When you're short on sleep and your focus suddenly drifts, your brain may be briefly slipping into cleanup mode. Scientists discovered that these attention lapses coincide with waves of fluid washing through the brain, a process that usually happens ...

Ibuprofen may be doing more than easing aches and pains--it could also help reduce the risk of some cancers. Studies have linked regular use to lower rates of endometrial and bowel cancer, likely because the drug dampens inflammation that fuels tumor ...

Researchers have found a reliable way to grow helper T cells from stem cells, solving a major challenge in immune-based cancer therapy. Helper T cells act as the immune system's coordinators, helping other immune cells fight longer and harder. The .. ...
