Arrow worms, or chaetognaths, are strange ocean predators that have puzzled scientists for more than a century. They have transparent, torpedo-shaped bodies, sharp grasping spines near their mouths, ...

Bananas are a staple for millions, yet their production is threatened by limited genetic diversity and breeding challenges. In a major advance, researchers analyzed over 2,700 triploid banana hybrids ...

Using a molecular technique known as the comet assay, researchers tracked oxidative DNA damage and repair in seeds stored for 2, 5, and 12 years under cold dry genebank conditions. Their findings ...

The genetic code acts as life’s instruction manual, telling cells how to build proteins from DNA and RNA. Though it's a marvel of molecular precision, the path it took to evolve remains unclear. Fresh ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...
