Scientists are calling for a lunar quarantine facility where samples from Mars, the Moon, and beyond would be examined before being brought to Earth. They warn that even a tiny alien microorganism could have unpredictable effects on Earth's ecosystems. By using robotic handling systems on the Moon...

Too much oxygen can become toxic when mitochondria fail to use it properly, contributing to severe neurological and mitochondrial diseases. Credit: Shutterstock New research suggests that low oxygen levels may help alleviate disease caused by defects in mitochondrial quality control. Oxygen is essential for people—and most other organisms—but more is not always better. When oxygen

Scientists at Lawrence Livermore National Laboratory recreated part of the intense chaos inside a nuclear fireball to better understand how radioactive fallout forms. Their experiments revealed that the way vaporized materials cool can dramatically change the particles that eventually form, especially for volatile elements like cesium...

A four-week diet change was enough to make some older adults appear biologically younger in a new University of Sydney study. Participants who reduced fat intake or shifted toward more plant-based protein showed improvements in key health biomarkers tied to aging. The strongest results came from a lower-fat...

Bacteria are constantly evolving to survive. One major consequence is that many harmful microbes are becoming resistant to antibiotics and disinfectants, creating serious challenges for medicine and public health. But not all bacteria are dangerous. In fact, many are essential to keeping the human body healthy. Now, scientists are exploring whether it may be possible

New chromosome-level evidence suggests Medicago evolution followed a more complex, and surprising path, than previously thought. A long-standing puzzle in plant evolution is starting to come together. Scientists have used a powerful imaging technique to trace how chromosome numbers changed in Medicago, a group that includes alfalfa...

Cells use a surprising “pearling” motion to evenly distribute mitochondrial DNA. This newly uncovered process may be key to understanding major diseases. Credit: Stock A strange bead-like motion inside cells may be the secret to keeping their DNA—and health—in balance. Mitochondria are often described as the power plants of the cell because they produce the

A natural extract from fruit waste may quietly transform everyday foods, offering improved nutritional effects and a more efficient use of resources. Credit: Shutterstock Researchers have developed a method to enhance bread by incorporating compounds from red dragon fruit peel, a commonly discarded by-product. A team led by Professor Zhou Weibiao at the National University
