New cell-scale robots can sense their environment, compute decisions, and move independently without magnetic or ultrasonic control systems.

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 ...

A cutting-edge therapy using base-edited immune cells is offering a major breakthrough for patients with one of the toughest forms of blood cancer, T-cell acute lymphoblastic leukaemia. By precisely ...

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 ...

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 ...

During Earth’s early days, bacteria developed a self-destruct strategy for detecting and destroying phages before they’re able to take over the cell’s machinery. While this does wonders for our immune ...

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 ...

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 ...

Ever since we started holding our cell phones up to our ears, there have been concerns that the radio waves they emit could cause cancer. While this makes sense in a Black Mirror kind of way—and some ...
