Scientists are warning that a little-known group of microbes called free-living amoebae may pose a growing global health threat. Found in soil and water, some species can survive extreme heat, chlorine, and even modern water systems--conditions that ...

Researchers have found that a natural aging-related molecule can repair key memory processes affected by Alzheimer's disease. The compound improves communication between brain cells and restores early memory abilities that typically fade first. ...

Pancreatic cancer may evade the immune system using a clever molecular trick. Researchers found that the cancer-driving protein MYC also suppresses immune alarm signals, allowing tumors to grow unnoticed. When this immune-shielding ability was ...

NASA is moving into a new phase of space exploration, with major progress across human spaceflight, science missions, and advanced technology. In just one year, the agency has launched multiple crewed and science missions, test-flown new aircraft, .. ...

Falling space junk is becoming a real-world hazard, and scientists have found a clever new way to track it using instruments already listening to the Earth itself. By tapping into networks of earthquake sensors, researchers can follow the sonic booms ...

A distant Sun-like star suddenly went dark for months, stunning astronomers who quickly realized something massive was passing in front of it. Observations revealed a gigantic disk of gas and dust filled with vaporized metals, swirling around an ...

Chronic inflammation may be quietly reshaping the colon and making it more vulnerable to early-onset colorectal cancer. Scientists found that colon tissue in younger patients was stiffer, even in areas that appeared healthy, suggesting these changes ...

Aging immune cells may be sabotaging the body from within. Researchers found that macrophages produce a protein that locks them into a chronic inflammatory state, making infections like sepsis more deadly in older adults. Turning off this signal ...

People with spinal cord injuries often lose movement even though their brains still send the right signals. Researchers tested whether EEG brain scans could capture those signals and reroute them to spinal stimulators. The system can detect when a .. ...

Locust swarms can wipe out crops across entire regions, threatening food supplies and livelihoods. Now, scientists working with farmers in Senegal have shown that improving soil health can dramatically reduce locust damage. By enriching soil with ...
