have developed a new model to study an early stage of human development, using human embryonic stem cells. The model resembles some key elements of an embryo at around 18-21 days old and allows the researchers to observe the processes underlying the formation of the human ...
Researchers have created a model that may explain the complexities of the origins of life. Their work, which appears in theJournal of the Royal Society Interface, offers new insights into how RNA signaling likely developed into the modern "genetic code." "Our model shows that today'sgenetic co...

but the team from Imperial were able to get the same results from a small sample of blood. Stem cells provide another option but they require careful reprogramming and monitoring to ensure they turn into the right cell type. The cells from blood form spontaneously when placed in the right env...
Earth supports a breathtaking range of geographies, ecosystems and environments, each of which harbors an equally impressive array of weather patterns and events. Climate is an aggregate of all these events averaged over a specific span of time for a par
