Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye—called the cornea—can heal from minor scratches within a single day. The brain is not one ...

Scientists in Melbourne have discovered how tiny electrical pulses can steer stem cells as they grow, opening the door to new improved ways of creating new tissues, organs, nerves and bones. Dr. Amy ...

Texas A&M researchers found a way to make stem cells produce double the normal number of mitochondria using nanoflower particles. These energized stem cells then transfer their surplus “power packs” ...

A new study shows, for the first time, that cow cells can naturally become immortal—continuing to divide indefinitely without genetic modification or any abnormal transformation. This overturns ...

The immune system has a tough job: When a tiny virus invades one of our cells, that cell must detect it and, within minutes, decide what to do. If the cell quickly self-destructs, that will prevent ...

Mary Brunkow, Fred Ramsdell, and Shimon Sakaguchi were awarded the 2025 Nobel Prize in Physiology or Medicine on Monday for their collective work in the discovery of specialized immune cells that roam ...

The Nobel Prize in Medicine was awarded on Monday to three scientists for discovering how a particular kind of cell can stop the body's immune system from attacking itself. The discovery of these ...

In a proof-of-concept experiment, scientists demonstrated that you can create and fertilize human eggs in the lab using sperm, genes from skin cells, and the "shells" of existing egg cells. When you ...

Scientists have used human skin cells to create fertilizable eggs capable of producing early embryos, an advance that could expand possibilities for fertility treatment, according to new research. The ...

Cancer cells can brainwash their neighbors. Like the CIA deploying secret agents to turn an enemy, tumors use a similar strategy to manipulate nearby cells. The tumors’ agents are mitochondria, the ...

UC Davis researchers Gant Luxton, Daniel Starr and Xiangyi Ding have used tiny fluorescent particles to study what is going on inside the cells of Caenorhabditis worms. They found that the cells are ...

Scientists have developed a groundbreaking cryo-optical microscopy technique that freezes living cells mid-action, capturing ultra-detailed snapshots of fast biological processes. By rapidly ...
