Scientists have identified a microbe capable of interpreting a single piece of genetic code in two completely different ways.

The origin of eukaryotes traced from Asgard archaea, revealing how complex cells evolved and led to animals, plants and ...

Biologists are confronting a problem they thought they had mostly solved: what, exactly, counts as life. A wave of ...

Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

Researchers uncovered a microbe that treats one stop codon as both a termination signal and an amino-acid instruction, revealing surprising genetic flexibility that may inspire new ways to influence ...

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” ...

Clearing aged cells from blood vessels could help reduce inflammation, improve blood sugar levels and counter insulin resistance, a mouse study finds. When you purchase through links on our site, we ...

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 method could one day become a treatment for infertility A decade of further research needed, scientists say The process overcomes an obstacle that stymied previous attempts Significant safety ...

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 ...
