However, 400 years later, scientists now believe that they could bring the dodo back to life through cloning of some of its closest living relatives.Scientists recently published a paper which identified the overall genomic structure of dinosaurs. The team achieved this by tracing the ancestors (祖...
This process, dubbed periodic cooking, was tested in real-life experiments alongside traditional hard-boiled, soft-boiled, and sous vide eggs. The results were analyzed for texture, taste, and chemical composition using advanced techniques such as Nuclear Magnetic Resonance and High-Resolution Mass...
